    abstract =  {This document presents techniques built upon BGP MPLS/VPN control plane mechanisms to construct virtual topologies for service chaining. These virtual service topologies interconnect network zones and constrain the flow of traffic between these zones via a sequence of service nodes so that interesting service functions can be applied to such trafic. This document also describes both routing control plane and network orchestration driven approaches to realize these virtual service topologies.},
