Deploying Next Generation SP Access Networks with the NCS540/NCS560 Platforms

© 2019 Cisco and/or its affiliates. All rights reserved. Cisco Public

Session Abstract

The NCS540 and NCS560 platforms are the next generation Access routers that extend the IOS XR programmable network to the SP Access. This session will focus on the architectures, deployment use-cases and positioning of these XR enabled routers in the access (Access/Aggregation/5G x-Haul/R-Phy) and provide an overview of the end to end solutions and differentiators for SP access.

Need to reduce overall expenditure, especially OPEX

Simplification and speed “is” innovation

Network complexities contributing to OPEX growth:

More bandwidth, RAN, Access, DC etc.

Monolithic Systems on Purpose-built

Multiple OS

Lacks Elasticity: Increase in provisioning and

management costs

Rigid Architecture: No Service/Network Views

Slow to introduce: Innovation, New capacity and

services

Telco offers Capacity

Service Provider Business ChallengeBandwidth Growth vs. Revenue Growth


Access Network Expectations

1. Higher System Capacity

2. High Data Rates

3. Lower Latency

4. Mass Connectivity

5. Energy Efficient

• 1000x capacity/km2

• 10-100x current 4G rates

• ~ 1ms desired

• 100x connected devices

• 10x Network and Device power savings

• 10x faster time-to-market

• 10x lower cost to serve

Functional Requirements

6. Agile

7. Cost effective

• Super-efficient, cost optimized

• Dynamic resource allocation - Agile

• Scale, High bandwidth and ultra-low latency

• Service Monetization - IoT Capable

• Power efficient

Benefits

• Monetization potential

Recouping 4G investments

• Device availability

• Regulatory issues : Spectrum allocation

• Use case / test data development

Aggregation

Metro/Access Network Domain Core Network Domain Data Center Domain

Limited Cross-domain Automation, Cumbersome Service Assurance

End-to-end service provisioning is lengthy and complex

• Routing protocols are blind to applications (Shortest-path for any traffic)

• Multiple network domains under different management teams

• Manual operations

• Heterogeneous underlay and overlay networks

IPMPLS (LDP, RSVP-TE)

L2VPN

Ethernet

L3VPN VXLAN

Complex E2E Quality of Service (QoS)

Traditional service creation process is a major challenge with explosion of access elements

BRKSPG-2159 11


Access equipment are often installed at places where environmental conditions are not ideal

All these factors make access network more costly to deploy and slow down service turn up

Extreme temperature

• Device must operate in very hot or very cold temperature

Size and power constraints

• Very tight spaces at remote locations

• Power feed is expensive

Lack of protection

• Increase security risks

• Exposed to elements which could impact device operation

BRKSPG-2159 12


Legacy equipment are going to end of life and operators are challenged to keep the TDM network going

How do I migrate my legacy equipment to the 21st

century

BRKSPG-2159 13


Service Providers’ Biggest Access Challenges

“Need optimized hardware platform for size and power

and innovative pricing model.”

“I need something that is easy to

deploy, configure, and monitor.”

“Need a high availability and

secured platform to minimize down

time.”

“l want open standards so I

don’t get locked into a single

vendor solution.”

“I want to migrate my high

touch legacy systems to IP/MPLS

Need to Grow Revenue, Reduce Costs, De-Risk with Security/Compliance and Improve Customer Experience – Faster

• It’s a new way of thinking about licensing being applied to all products

• Provides customers with consolidated software ownership and usage information

NCS 560 / RSP4 – ISSU

• The RSP cards run in 1:1 redundancy model. They talk to each other over backplane directly, managed by IOFPGA.

• The LC slots support different types of interface modules (IM’s) like 16x1G, 8x10G, 2x100G. There is no dedicated CPU on the LCs, and the IMFPGA manages the module in terms of programmability and monitoring.

• IMs bi-cast all ingress packets to both RSP cards, which perform the switching/exception handling.

• Egress traffic from the card that runs Standby XR VM is discarded by the IM, using a hardware MUX logic. The MUX is flipped whenever there is an XR redundancy switchover, so that packets from the new Active RSP starts getting sent out to wire.

• NCS 560 RSP ISSU uses Virtualization (2 VM’s from the Intel CPU)

• With Virtualization, we spawn a second instance, running in parallel with the first instance that executes as part of everyday’ s operations.

• The second instance is the target to which the system is upgraded to, and is said to be V2, while the first instance is said to be V1.

• The V2 instance learns the configuration from V1, as well as the initial operational data (routes, adjacencies, segments, etc.). It is updated in real-time when operational data is changing (route discovery, etc.)

• 1st VM (V1 Active & V2 Standby) = Host OS and Admin VM (aka Calvados VM)

• 2nd VM (V1 Active & V2 Standby )= IOS-XR (Service) VM (aka XR VM)

• The diagrams on the next slides illustrate ISSU from one release to another with:

• Fully Redundant Control / Data Plane

• XR Admin Plane (Calvados VM) has active modules spread across Active & Standby RSP

• Control planes are in sync allowing for stateful switchover

• XR Nodes on both RSPs (XR VM)

• NPU in hot-standby mode

• Each Interface Module connects to both Data Planes of the RSP’s

Calvados VM ISSU consists of three phases: Prepare, Activate & Commit and is done one RP at a time, as shown above:

1. In Prepare phase, new V2 VM get spawned / loaded with new V2 packages on Standby.

2. Post Reload (Activate) of Standby RSP, V2 VM takes control

3. The last final step involves the “Commit” stage, where Host OS and Admin VM are finalized and committed to the system

compatibility checks are done. The v2 VMs are instantiated, XR processes are spawned, configuration is downloaded to the spawned VMs, v2 processes sync with their corresponding v1 instances on the Active RSP VM.

BRKSPG-2159 82


Cisco 5G-Ready TransportSegment Routing - FlexAlgo

• Flex-Algo

• The algorithm is defined by the operator, on a per-deployment basis

• Flex-Algo is defined as

• The minimization of a specified metric: IGP, delay, …

• The exclusion of certain link properties: link-affinity, SRLG, …

• Leverages the SRTE benefits of simplicity and automation

• Automated sub-50msec FRR (TILFA)

• On-Demand Policy (ODN)

• Automated Steering (AS)

• Example

• Operator1 defines Flex-Algo 128 as “minimize IGP metric and avoid link-affinity “green”

• Operator2 defines Flex-Algo 128 as “minimize delay metric and avoid link-affinity “blue”

BRKSPG-2159 83


Cisco 5G-Ready TransportSR for Transport Network Slicing

• Cisco’s SR/Diffserv/VPN is well proven soft slice approach

• TE / Flex Algo can harden the approach

• High Reliability built-in mechanisms: TI-LFA (automated 50msec convergence), ECMP, Anycast SID, backup disjoint paths

• Full programmability and control over the end2end path definition -explicit path that complies with defined network slice constraints

• Simple and limited configuration required @node level with ODN (on demand next hop)– scalable and dynamic network slice life cycle changes (create, modify and delete)

• Provides quasi realtime measurements of link and node metrics to the SDN controller – continuous and automated network slice SLA compliance
