SERVICE PLACEMENT FOR INLINE SERVICES CHAINING WITH MULTIPLE INSTANCES

摘要

A system and method for placing inline services having multiple instances in a service provider network. In one implementation a topology of the service provider network and services to be placed therein are defined. Using service chaining policy requirements the number of service instances etc. as input services and their multiple instances are placed within the network such that an overall network metric is optimized for all subscriber data flows. The implementation uses softwared defined networks (SDN) and OpenFlow.
