    abstract =  {This document presents the techniques built upon BGP/MPLS IP VPN control plane mechanisms to construct virtual service topologies for service chaining. These virtual service topologies allow a sequence of service nodes to be visited across multiple zones in a data center to form a service chain. The method uses service topology specific Route Targets (RTs) in addition to general purpose RTs.},
