Each SR segment endpoint node provides SRv6 Endpoint Behaviors, including Prefix/Adjacency Segments, VPNs, and Binding Segments.

Service Function Chaining (SFC) {{!RFC7665}} can be used in various scenarios (e.g. FW, IPS, IDS, NAT, and DPI).
SFC based on Segment Routing (SR) is defined in {{!I-D.draft-ietf-spring-sr-service-programming}}, which describes some SRv6 endpoint behaviors, such as End.AS/AD/AM, are necessary for using SR-unaware functions.

This architecture is based on SDN {{!RFC7426}} separating the forwarding plane (FP), control plane (CP), management plane (MP), and application plane (AP).
Each plane has the following roles:

* Forwarding plane: classifies packets and encapsulates SRH, forwards them, and applies endpoint behavior.
* Forwarding plane: classifies packets and encapsulates SRH, forwards them, and applies SRv6 Endpoint Behavior.
* Provides SR-aware function using End.AN.
* Classify flow and apply them to TE application with PBR.
* Ensures redundancy with Anycast.
