This study is a rudimentary analysis of segment routing with MPLS (SR-MPLS) use case for service function chaining (SFC) on protocol-independent switch architecture (PISA). Segment routing is a packet forwarding method that leverages both source routing and packet encapsulation. SFC is packet steering through ordered service function (SF) path technique where SFs are firewall, deep packet inspection, network address translation, etc. Goal of this study is to investigate the service function chaining domain use case scenario for PISA data plane incorporating SR-MPLS as transport. We developed program code for SFC domain elements in a programmable protocol independent packet processing (P4) and python languages. The outcome of this study is functionating SFC domain emulation in Mininet environment. Emulation results shows that SR-MPLS makes minimal overhead for all emulated SF paths in generalized proportion of approximately 1/1000 from overall transmission rate. Results also reveal a minimalistic transmission rate dependency on path length in generalized proportion of approximately 1/40 of transmission rate drop between shorter and longer SF paths. It’s evident that SR-MPLS is fit to be used for SFC on PISA switches.
