Cisco weblog > SP360: carrier provider
As they head to MPLS + SDN + NFV World Congress this week, i'm reminded of conversations I actually fill with service suppliers unseemly the time. They inform me how they necessity complete options to answer their company needs, now not just a slice of a technology stack. They inform me they necessity application that supports an end-to-end structure that's tightly built-in with their OSS/BSS systems, and runs on a full latitude of hardware. And, they necessity it to exist primary to implement and straightforward to use.
it is exactly what they created with Cisco IOS XR. more than 150 provider providers - including one of the greatest net gamers unseemly over the world - fill deployed their subsequent technology containerized/virtualized IOS XR, which is the richest networking stack obtainable in the marketplace, with trade-leading innovations in IP transport (section Routing), IPv6, features (EVPN), Visibility (Streaming Telemetry), security (MacSec), Programmability (Yang), 5G (clocking/synch) and a total lot extra.
Our IOS XR has three leading areas of innovation:
An example of this innovation is IOS XR's aid of Linux containers, which they delivered returned in 2015 with IOS XR 6.0. They architected their IOS XR software stack to hasten in containers and provide aid for client and third birthday party functions in containers too, which is feasible since the utility distribution helping IOS XR is in keeping with Open Embedded Linux. at the identical time, they aligned their deployment and automation capabilities with industry requisites (Netconf/gRPC) as well as server workflows (iPXE, ZTP, Ansible, Chef, Puppet and more). basically, they confirmed IOS XR running as allotment of a Mesos Cluster at MesosCon 2015.
We additionally made bound IOS XR is obtainable on Cisco and service provider silicon across a wide selection of hardware systems, ranging from 1 RU to multi-chassis programs. It runs in a digital shape aspect on confidential x86 compute systems with the entire feature set and a high-performance information airplane. With assist for actual and virtual, IOS XR gives service providers precise choice in their designs, whereas offering a typical operational event end-to-conclusion. they are additionally laser focused on making their application effortless to develop exercise of and enforce. we're designing with ruthless ease in intellect. you can study extra about full IOS XR capabilities on https://xrdocs.github.io or succeed @xrdocs on twitter.
i'm so pleased with their crew for his or her confirmed improvements in application that launched the trade to original heights returned in 2015 and soundless a ways outpaces the rest available on the market nowadays.
if you are attending MPLS+SDN+NFV World Congress develop positive to register for the event online for Cisco's workshop to gain lore of more about IOS XR and meet their consultants.Tags:

6.1. Per-Port UBRL (user-based fee Limiting)
UBRL adopts microflow policing potential to dynamically gain lore of traffic flows and fee confine every exciting movement to someone fee and, as such, is a enormously profitable and efficient policing device, principally on the distribution ayer in a medianet campus network.
UBRL is available on Supervisor Engine V-10GE with NetFlow support. UBRL can exist utilized to ingress site visitors on routed interfaces and is customarily used in environments where a per-user, granular expense limiting mechanism is required, reminiscent of at the distribution layer, to give a second line of policing defense within the campus. dote other policers, UBRL can also exist used to drop or commentary exceeding flows.
A stream is defined via five-tuples (IP source tackle, IP vacation spot tackle, IP protocol field, Layer 4 protocol source, and destination ports), which can exist the identical for each packet within the flow. circulate-primarily based policers succeed a unique policy to discrete flows while not having to specify the virtually-infinite tuple-combinations. UBRL can also exist utilized with source or vacation spot circulation masks; these masks succeed an aggregate microflow policing policy to dissimilar flows sharing the selfsame source or IP destination addresses.
in the per-port UBRL model, a class map fits on a microflow basis and aggregates these through source addresses. Then a policer applies an admixture confine to unseemly microflows sharing a typical supply IP tackle, remarking site visitors in excess of the policing cost.
Remarking is performed by artery of configuring a policed-DSCP map with the international configuration command qos map dscp policed, which specifies which DSCP values are topic to remarking (if out-of-profile) and what these values should exist remarked to (which within the case of scavenger class QoS policies, the remarking cost is CS1/DSCP 8).
UBRL is supported on Layer three interfaces and might exist applied on both a per-port or per-port/per-VLAN-groundwork

6.2. Per-Port/Per-VLAN UBRL (consumer-primarily based expense Limiting)
In distinction with the previous instance, if the campus distribution obstruct is the exercise of a Layer 2/Layer three design, and as such has Layer 2 trunked interfaces (TenGigabitEthernet 1/1 and 1/2) connecting it to the access layer switches, then UBRL can also exist applied on a per-port/per-VLAN groundwork. in this case, divide UBRL guidelines may also exist utilized to each VLAN traversing the trunked interfaces by artery of per-port/per-VLAN UBRL policies as every VLAN is routed in the course of the swap.
To spotlight policy flexibility, further stages of classification are blanketed in this 2d UBRL instance (which by the artery can also exist utilized to the per-port UBRL model). instead of applying a blanket UBRL policy to unseemly endpoints, divide UBRL polices may also exist applied to various kinds of endpoints or application-and-endpoint-mixtures. as an instance, VoIP from Cisco IP telephones within the VVLAN can exist cost restricted to 128 Kbps, while signaling traffic from these endpoints can exist confined to 32 kbps. in a similar way, TelePresence endpoints within the VVLAN (which trace their media flows to CS4) can exist restricted to 25 Mbps. unseemly other endpoint-generated site visitors within the VVLAN can exist limited to 32 kbps per endpoint.
equivalent coverage granularity can exist applied to the DVLAN policer, if preferred. however in this example, a simplified DVLAN policer is applied to unseemly flows to develop positive that any DVLAN endpoint transmitting at more than 5% capacity (an illustration price) of the entry facet 10/100/a thousand switch ports are discipline to statistics plane policing/scavenger class QoS.
Static DSCP-have faith is configured on the physical ports and the per-port/per-VLAN UBRL policers are utilized to their respective VLANs within the trunked interface.

Per-Port Microflow Policing model
Microflow policing dynamically learns traffic flows and rate limits each and every unique circulation to an individual fee and as such, is a incredibly helpful and productive policing tool, above unseemly at the distribution layer in a medianet campus community.
Microflow policing can exist utilized to ingress site visitors on routed interfaces and is usually utilized in environments where a per-person, granular expense limiting mechanism is required equivalent to those of on the distribution layer which to supply a 2nd-line of policing protection in the campus. dote other policers, microflow policing will also exist used to drop or statement exceeding flows.
Microflow policers are enabled with the police circulate policy-map type-motion command. A saunter is described by 5-tuples (IP supply tackle, IP vacation spot handle, IP protocol field, Layer four protocol supply, and destination ports), which might exist the equal for every packet in the circulation. Microflow policers succeed a unique coverage to discrete traffic flows, while not having to specify the well-nigh-infinite tuple combinations. Microflow policing can even exist utilized with source or destination circulate masks (with the masks src-only and mask dest-best not obligatory key words, respectively). These masks then exercise an admixture microflow policing coverage to distinct flows sharing the identical source or IP destination addresses.
within the per-port microflow policing model, a movement-primarily based policer is utilized with a mask src-most efficacious alternative and applies an aggregate restrict to unseemly microflows sharing a common supply IP handle, remarking traffic in extra of the policing cost.
Remarking is carried out by configuring policed-DSCP maps with the world configuration commands mls qos map policed-dscp regular-burst (which specifies the exceeding remarking action) and mls qos map policed-dscp max-burst (which specifies the violating remarking action, in the case of a twin rate policer). These commands specify which DSCP values are domain to remarking if out-of-profile and what cost these should soundless exist remarked as (which within the case of records aircraft policing/scavenger type QoS policies, this value is CS1/DSCP eight).
even if unique cost policers are used, it is recommended to configure the mls qos map dscp policed max-burst markdown map, because the maximum_burst_bytes parameter for the policer is set to equal to the normal_burst_bytes parameter, until explicitly targeted in any other case. In different phrases, the PIR is set to equal the CIR, until explicitly distinct in any other case, and consequently the exceed-motion policed-dscp-transmit keyword phrases explanations PFC QoS to trace traffic down DSCP values as defined via the policed-dscp max-burst markdown map (and not the policed-dscp standard-burst markdown map).

Per-VLAN Microflow Policing model
In contrast with the outdated instance, if the campus distribution obstruct is using a Layer 2/Layer three design, and as such has Layer 2 trunked interfaces (TenGigabitEthernet 3/1 and 3/2) connecting it to the access layer switches, then microflow policing will also exist applied on a per-VLAN foundation. during this case, divide microflow policing policies will also exist utilized to every VLAN.
To highlight policy flexibility, further ranges of classification are included in this second microflow policing illustration. incidentally these additions can even exist applied to the per-port microflow policing model. in its station of applying a blanket microflow policer to unseemly endpoints, divide microflow policers may also exist utilized to various kinds of endpoints or application-and-endpoint-combos. as an example, VoIP from Cisco IP phones in the VVLAN can exist policed to 128 Kbps, whereas signaling traffic from these endpoints can exist policed to 32 kbps. similarly, TelePresence endpoints in the VVLAN (which trace their media flows to CS4) may also exist policed to 25 Mbps. unseemly different endpoint-generated traffic within the VVLAN may also exist policed to 32 kbps per endpoint.
similar policy granularity may also exist utilized to the DVLAN policer, if preferred. although in this instance, a simplified DVLAN policer is utilized to unseemly flows to exist positive that any DVLAN endpoint transmitting at greater than 5% capacity (an example value) of the access aspect 10/one hundred/a thousand switch ports are discipline to facts aircraft policing/scavenger type QoS.

in an worry to develop unavoidable genuine quit to conclusion QoS throughout the environment, the voice gateways ought to exist configured to accurately trace manage and bearer traffic sourced from their strategies, together with MGCP, H.323, and SIP.
by using default, MGCP gateways trace bearer site visitors with DSCP EF and manage traffic with AF31. this is not in keeping with existing requisites. here adjustments may soundless exist made to unseemly deployed MGCP gateways.
through default, H.323 and SIP dial-friends trace bearer site visitors with DSCP EF and control traffic AF31. here is no longer consistent with latest requisites. The commemorate changes may soundless exist made to VOIP dial-friends on unseemly deployed H.323 and SIP gateways.
WAN powerful of provider
when you try to assure site visitors service over long distance involving WAN circuits such as factor-to-aspect, MPLS, and Metro Ethernet; then there fill to exist QoS implementation on your WAN gateway of unseemly ends of your location. additionally, your WAN QoS implementation ought to match QoS specification your provider issuer makes exercise of to maintain end-to-end QoS provider.
As illustration, let's insist you fill got aspect-to-factor 1 Gbps Metro Ethernet circuit out of your carrier issuer to interconnect two of your areas. The carrier company has specification that 5 Mbps is unavoidable for class of provider (CoS) priority 5 (EF) site visitors, 5 Mbps is unavoidable for CoS precedence 2; whereas the ultimate bandwidth is freely used for CoS default site visitors.
Let's assume you fill got IP cellphone that uses DSCP EF 5 or CoS 5 of UDP port latitude 16384 - 32767 for voice traffic and makes exercise of DSCP AF forty one (CS three) or CoS 3 of SIP (UDP and TCP port scope 5060 - 5061) and SCCP (TCP port latitude 2000 - 2002) for signalling traffic. within LAN, you typically let these specification as default while setting unseemly LAN change access and trunk ports to well known these traffic. as soon as the site visitors is headed to the aspect-to-element circuit, then in some artery you ought to regulate the traffic specification in case you intend to match your traffic specification with the carrier provider specification.
expect you want to utilize the carrier provider CoS 5 for the voice site visitors, CoS 2 for the signalling, and ultimate bandwidth is utilize for different site visitors equivalent to e-mail, internet, and file sharing. hence because the traffic is ready to fade away one vicinity over the aspect-to-factor circuit to attain your different vicinity, you should map your present CoS 5 site visitors to the provider company CoS 5, map your present CoS three site visitors to the provider provider CoS 2, and map remaining traffic to the carrier company CoS default traffic.
When the traffic is already going over the point-to-factor circuit from one station and arrive at the other place, you necessity set your traffic lower back to its customary specification as a artery to sound your traffic specification. hence because the traffic arrives on the different region, you deserve to map the service company CoS 5 traffic to the original CoS 5 traffic, map the carrier issuer CoS 2 to the original CoS 3, and map terminal traffic as default site visitors.
As you may notice that these WAN QoS mapping happens for your WAN gateway whereas LAN QoS mapping happens on your LAN. Following is one answer how the WAN QoS mapping and configuration gape like. the faith here is that your WAN gateway is a router using GigabitEthernet 0/0/0 port to hook up with the WAN circuit.
for more info involving these QoS commands, select a gape at birthright here Cisco hyperlink.Configuring the Modular trait of carrier

The tips posted here's a summarized edition of the Cisco AVVID QoS Design guide. The grownup who posted here is now not liable for any community complications or any throe led to with the aid of configuring their router to here specification. If unsure, open up a Cisco TAC case which a Cisco Engineer will come by in contact to aid you attach in coerce or troubleshoot your design or concern respectively. You may additionally query the Cisco discussion board neighborhood for any assistance however group accept no liability for any recommendations made which might exist then implemented.
The illustration beneath is using a Cisco 79xx IP cell, 2924 swap (12.0(5)XU EN, and a 2600 Router (12.2(11)T IP/FW/IDS PLUS IPSEC 56). exist unavoidable the types of IOS that you simply're working assist the commands used before enforcing in a creation ambiance. It additionally assumes that you are the exercise of divide VLANs for statistics and voice (VLAN a hundred for records, and 101 for voice).
This instance assumes the following community setup:
Configuring the 2924 swap:
The above port configuration allows for both voice and information traffic from divide vlans. Cisco IP phones immediately capitalize 802.1q trunking and 802.1p COS tagging, so that they can tag unseemly outgoing voice traffic with an L2 COS of 5, and a L3 IP precedence of 5. The 'switchport priority prolong cos 0' ensures that unseemly data site visitors has it's L2 COS tag re-classified as 0. this can ensure a computer connected to the phone is not additionally classifying its site visitors.
moreover, if your change supports inline energy, add here to the above configuration: 'energy inline auto'
note:The 'pace auto' command is extremely vital. Cisco IP telephones default to auto-negotiation for accelerate and duplex. If the swap port is determined to 100baseT full-duplex, the IP cellphone immediately sets its port to 100baseT half-duplex, inflicting a duplex mismatch.

subsequent, they create classification maps for each and every type of traffic.
Then create a policy map for the classes:
The policy-map on the router areas unseemly voice site visitors into the priority Queue, which is given 240kbps of bandwidth. unseemly signaling site visitors is in a class-based mostly queue with 16kbps of bandwidth. And unseemly different traffic is queued using Weighted objective Queuing.
To determine how an impecunious lot bandwidth to provide to voice traffic:number of simultaneous calls X eighty (for g711u)variety of simultaneous calls X 11 (for g729)
finally, apply the policy to the interface:

Congratulations to Christina Applegate and her fiancé Martyn Lenoble! The satisfied yoke are expecting their first infant, people studies.
Applegate, 38, and Lenoble, 41, grew to exist engaged on Valentine’s Day after two years of relationship. They haven't set a date for the wedding.
The Married… with babies actress, who underwent a double mastectomy in 2008, recently mentioned that she plans to fill “plenty” of infants: “[I want] loads of babies. smartly, now not loads of miniature ones, but a couple!”
Having laid out my views partially I, let me spin to the exact information concerning hybrids — each from an environmental and fiscal viewpoint.
How effect carbon emissions per mile driven examine for various cars? The Volt is expected to exist “under $30,000” with a 1.0L engine. evaluate this to the Corolla, with a 1.8Lengine (peak hp of 126; 31 mpg) and a cost of $14,four hundred. It’s cost noting that this is within the optimistic, no-gasoline-use scenario for the Volt, computed below along with carbon emissions for the Volt working on cellulosic ethanol and gasoline, and emissions for similar-sized ICE automobiles. questions on the Volt’s exact usage patterns stay: what number of americans will recharge prevalent? how many of total miles can exist on the grid, and what percentage on fuel?2010 2017 2017 (with 50% enlarge in ICE mpg effectivity) automobileCO2 Emissions — grams/ mile month-to-month cost (automobile+gasoline) CO2 Emissions — grams/ mile monthly cost (automobile+gasoline) CO2 Emissions — grams/ mile month-to-month suffuse (vehicle+gasoline) Toyota Prius 238 $490 238 $490 159 $468 GM Volt On electrical energy144 $623 a hundred and forty four $623 144 $623 GM Volt Cellul. E85 – – 55 $641 37 $628 GM Volt gasoline handiest 219 $661 219 $661 146 $641 GM Volt gas+Elec (1:1) 182 $642 181 $642 a hundred forty five $632 Toyota Corolla (ICE Engine) 353 $385 353 $385 235 $353 Toyota Corolla (Hypothetical FFV version) 282 (Corn E85) $387 88 (Cellul. E85) $355 58 (Cellul. E85) $334
notice: A hypothetical “plug-in Prius” with a Volt-sized 16kWh battery would probably suffuse more than the Volt. therefore the above evaluation of a plug-in Volt and a hybrid Prius is unfair to the GM Volt. The monthly can suffuse comprises the month-to-month amortized suffuse of buy (7.5 percent personal loan — fully financed over 5 years) + suffuse of gas (1,000 miles/month). Battery cost of $7,600 (at $400kWh + $1,200 control) in 2010 and $four,000 ($200kWh + $800 handle) in 2017 is covered within the Volt buy rate of $30,000 — these battery can suffuse estimates are forty-60 p.c abate than current estimates of $700-1000kWh and automaker margin is not covered. fuel suffuse assumptions of $0.11c/kWh electrical energy (U.S. typical per EIA) and 5 miles per kwh for the Volt, $3.00 gas can suffuse to consumers (roughly simply the fabric cost of “oil” in gasoline at $100 oil fee, earlier than taxes — actual prices are more likely to exist larger for buyers if oil prices reside high), $2.25 per gallon corn E85 to patrons earlier than taxes ($1.seventy five creation suffuse per gallon), and $1.50 per gallon cellulosic E85 (in keeping with $1.00 construction suffuse before taxes) in 2017. A 25 % mileage discount is used with ethanol (equal to current typical EPA de-rating for E85). doesn't encompass anticipated growth on E85 mileage relative to gasoline or the carbon emissions from battery manufacturing, which can exist more likely to develop Prius and battery numbers about 10-20 % worse on carbon emissions. not one of the fees account for subsides or taxes, which they signify on will exist zero or equal for unseemly technologies by 2017. No car impute alterations are assumed.
The numbers are always estimates, and apples-to-apples comparisons are complicated. especially, they effect not consist of the carbon emissions for battery manufacture amortized over the assumed a hundred,000-mile life of the battery. furthermore, speculation persists that the GM Volt battery may exist leased to consumers — and that the $30,000 expense tag is not inclusive of any leasing expenses. i suspect these errors are material, and develop the electric numbers flaunt materially greater than they are. (Can someone provide a source for an inexpensive estimate?)
The assumptions in the back of this desk are as follows: the Volt receives 5 miles/kwh. Given U.S. electrical grid emissions of about 1.35lbs per kWh (EIA estimates), that offers us a per-mile emissions flush of roughly 0.32 lbs/mile (after adjusting for an electrical roundtrip storage effectivity at 85 % for the battery, and assuming it's running on battery alone) or about one hundred forty four grams of carbon dioxide per mile. On gas on my own (assuming no battery charging from electrical energy) the selfsame car’s emissions would exist 219 grams per mile.
the exercise of best cellulosic ethanol, the selfsame car would fill seventy five p.c lessen emissions, or 55 grams per mile (assuming vans, and many others., supplying biomass, and transportation soundless working on fossil gasoline). we've modeled gasoline emissions for tank-to-wheels to exist 80 % of that from neatly-to-wheels emissions (roughly what the EIA uses). Any aid in refining these numbers can exist preferred.
The percentage of coal within the U.S. grid is anticipated to saunter up, now not down. contrary to most forecasts, I feel they can effect greater than that and confine coal-powered electrical energy to the factor the station its percentage will decline (we fill investments to develop renewable grid electricity cheaper than subsequent-gen IGCC coal vegetation), but the decline may exist gradual given standard power plant lifespans. regardless of what they could wish for — using on photo voltaic or wind power — the reality is likely to exist distinct. For these of you who want to compute photo voltaic PV panels in your roof, its helpful suffuse is between $0.25 (reasonably-priced panels in sunny Arizona?) to $0.50 (Foggy Seattle?) per kWh, based upon your suffuse and the location of the panels. In a number of locations wind can exist most economical, however that could exist for a minute minority of car house owners.
What concerning the can suffuse of driving a mile? when they come by to the incremental clean-grid fees, renewable electricity is anticipated to cost about $0.10-0.15c/kWh (previous to taxes; $0.06-0.10 per kWh brought to utilities) dropped at the customer at any mammoth scale, or about $0.02-0.03 per mile from a automobile of the Volt class. A construction suffuse of $1.00 per gallon of biofuel (i believe lessen costs are probably in 10-15 years) will doubtless outcome in a $1.50 client fee component (ahead of any taxes, which vary with the aid of state), so one would fill to come by 50mpg (very doable; well-nigh the GM Volt fuel-simplest mileage) in a flex-gasoline automobile to come by the selfsame variable cost per mile driven.
yes, I effect forecast — inside the decade — a powerful flex-fuel engine to come by the equal mileage on biofuels as it does on fuel (as an example, an ethanol-in a position engine working at a compression ratio of 16 — ethanol’s greater octane rating means that today’s engines aren't optimized for it). which will boost ethanol mileage via one other 25 p.c, which is not figured into their month-to-month cost reduction calculations. I should soundless exist clear that each one numbers are necessarily approximations, probably to inside 25 percent.
