Key Takeaways Service Provider Enterprise Financial WEB / Over-The-Top (OTT) Network Engineer Network Operator Network Manger/Director/VP Product Manager Planning Team System Engineer Consulting System Engineer Software Engineer/Manager SDN WAN/MAN Orchestration is deployable and now Segment Routing provides simplicity and scalability by expressing explicit path in the packet Fully automated 0ms protection by is enabled by default Provide first strong step to the Unified Forwarding Plane and to Application Engineered Routing Copyright SDNCentral LLC.

6 WAN / MAN Orchestration using SDN Segment Routing Derek Tay, Jose Liste October 201
7 What is Segment Routing? Source Routing The source chooses a path and encodes it in the packet header as an ordered list of segments The rest of the network executes the encoded instructions without any further per-flow state Segment: an identifier for any type of instruction Forwarding or service Traffic Engineering with Segment Routing Distributed computation or Centralized No extra protocol (e.g. RSVP-TE) No midpoint state

10 Demonstration Objectives In this demonstration you will experience the following: Cisco WAN Automation Engine (WAE) acting as Controller of an MPLS Segment Routing network built with ASR 9000 and XRv devices Programmatic access to Cisco WAE requesting instantiation of traffic engineering policies in the network Path Computation Element (PCE)-initiated Segment Routing Traffic Engineering (SR-TE) policies Automatic re-optimization of existing paths triggered by network topology changes (Link Failures and Link Performance Degradation)
11 Demo Components REST APIs APP WAE WAN Controller PCEP BGP-LS P1 CE1 PE1 PE2 CE2 IS-IS Segment Routing / MPLS network P2 BGP-LS = BGP Link State PCEP = Path Computation Element Protocol
12 Initial State 0 Using MPLS labels propagated via SR ISIS extensions, traffic CE1-CE2 travels over LSP following IGP best path Lo0 SID POP (PHP) P1 20 CE1 PE1 Lo0 SID PE2 Lo0 SID CE2 P2 Lo0 SID IGP metric = RED TE metric = BLUE
13 Application Request 1 APP 4 WAE 2 WAE computes path meeting constraints Path found!!! In-contract == cumulative TE metric = REST API APP requests PATH PE1-PE2 with latency < 4 msec;; or otherwise lowest possible when out-of-contract WAE replies to APP Path found in-contract WAE deploys path onto the network using PCEP Forwarding instructions in SR ERO: Follow IGP path to P2 then follow IGP path to PE2 P CE PE1 POP (PHP) 0 PE2 Lo0 SID CE P2 Lo0 SID POP (PHP) IGP metric = RED TE metric = BLUE
14 6 Link Failure 9 CE1 APP WAE deploys new path onto the network Forwarding instructions in SR ERO: Follow IGP path to P2 then follow low TE metric link P2-P1 then follow IGP path to PE2 Network self-heals in less than 0-msec Fast Reroute (TI-LFA) Optimal backup path No controller involvement!!! PE1 POP (PHP) P1 0 P2 WAE Lo0 SID Adj SID WAE reacts to topology changes Re-optimizes path in the network Path found!!! In-contract == cumulative TE metric = 40 No need to communicate to APP!!! BGP-LS update sent to WAE PE2 Lo0 SID Link Fails CE2 IGP metric = RED TE metric = BLUE Adj SID = Adjacency SID TI-LFA = Topology Independent Loop Free Alternate
15 Link Performance Degradation APP 1 WAE 13 WAE reacts to topology changes Re-optimizes path in the network Path found!!! Out-of-contract == cumulative TE metric = WAE replies to APP Path found out-off-contract WAE deploys new path onto the network Forwarding instructions in SR-ERO: Follow low TE metric link PE1-P1 then follow IGP path to PE2 CE1 POP (PHP) PE P TE DB update is propagated via BGP-LS to WAE PE2 CE2 Adj SID Excessive Link Delay e.g. 60 msec 11 Router adjusts TE metric P2 Lo0 SID IGP metric = RED TE metric = BLUE TI-LFA = Topology Independent Loop Free Alternate
16 Summary In this demonstration you experienced the following: Application programming the Segment Routing network to deliver traffic through WAN Cisco WAN Automation Engine (WAE) acting as a WAN Controller Path Computation Element used to instantiate SR-TE policies Automatic 0ms protection in case of failures Automatic re-optimization of existing paths triggered by network topology changes
