INTER-DOMAIN SERVICE FUNCTION CHAINING
First Claim
1. A method comprising:
- receiving a packet in a service function chain at a network device located at a border of a first administrative domain, the packet comprising a service function path identifier and a service index;
processing the packet at the network device, wherein processing comprises modifying the packet based on said service function path identifier and said service index to direct the packet to a second administrative domain; and
forwarding the packet from the network device to said second administrative domain for processing in said service function chain;
wherein said service function chain extends over said first and second administrative domains.
