Abstract
A packet forwarding method. The method reacts to service function events promptly by recalculating a more streamlined service function path (SFP) for a packet flow of a service function chain (SFC). Service functions (SFs) and service function forwarders (SFFs) collaborate to serve a SFC packet flow and bypass SFs belonging to the same SF group which does not provides functional service to packets of the flow.
