To the message carrying NSH heading parsed, according to the information in NSH head, message is turned
Issue corresponding SF process；SF is responsible for carrying out corresponding business function process to the message receiving, place
After having managed, further update NSH heading and by update after message be transmitted to E-Packet to oneself
SFF；SFF encapsulates according to the corresponding transport layer of the information searching in NSH message further, to NSH
Message carries out the encapsulation of overlay, and forwards the message to next-hop SFF.NSH Proxy main representative
SFF, is interacted with the SF not perceiving NSH heading.It is exemplified below, for using IPv4-GRE
After the overlay technology of (Generic Routing Encapsulation, generic route encapsulation), from
Complete message form that Classifier sends out is as shown in Fig. 2 i.e. in original message (original
Packet) NSH head, IPv4-GRE head, L2 head on outer envelope.
From the point of view of chain of command, the classifying ruless of SFC and the definition of business function chain and NSH are controlled by SFC
