Abstract:
Some working groups of the IETF and other Standards Developing
Organizations are now discussing use cases of a technology that
enables data packets to traverse appropriate service functions
located remotely through networks. This is called Service Chaining
in this document. (Also, in Network Functions Virtualisation (NFV),
a subject that forwarding packets to required service functions in
appropriate order is called VNF Forwarding Graph.) This draft does
not focus only on SFC method, and thus, use the term "Service
Chaining". SFC may be one of approaches to realize Service Chaining.
There are several Service Chaining methods to forward data packets to
service functions, and the applicable methods will vary depending on
the service requirements of individual networks.
This document presents the results of analyzing packet forwarding
methods and path selection patterns for achieving Service Chaining.
For forwarding data packets to the appropriate service functions,
distribution of route information and steering data packets following
the route information, are required. Examples of route information
are packet identifier and the routing configurations based on the
identifier. Also, forwarding functions are required to decide the
path according to the route information.
