Alibaba’s Predictable Global Network Traffic Steering Service on SRv6

Presented by Yongping Tang (Alibaba) Alibaba global network (AGN) carries traffic between data centers and internet users, providing network services for businesses like cloud and e-commerce. In the past years, we have built up an SR-MPLS TE network and an SDN controller system to steer traffic based on QOS. With our SONiC based SRv6 router, eSR, now a reality, we are evolving our network into SRv6. Our SDN system also starts to provide a new service model called predictable endpoint-network synergy traffic steering. We define our traffic control behaviors as different services with explicit metrics. Business apps running on hosts can subscribe to these services by getting service SIDs. With SRv6's extended header programming ability, hosts at any granularity can get their customized service powered by optimization algorithms running in our control system with accurate traffic behavior result estimation, thus called predictable. This new service model will become our standard solution for new application scenarios.
