Service Function Chaining Based on Segment Routing Using P4 and SR-IOV (P4-SFC) [PDF]

, 2020
Abstract In this paper we describe P4-SFC to support service function chaining (SFC) based on a single P4-capable switch and off-the-shelf components. It utilizes MPLS-based segment routing for traffic forwarding in the network and SR-IOV for efficient packet handling on hosts.
