Abstract:
This document provides some exemplary use cases for service function
chaining in mobile service provider networks. The objective of this
draft is not to cover all conceivable service chains in detail.
Rather, the intention is to localize and explain the application
domain of service chaining within mobile networks as far as it is
required to complement the problem statement [RFC7498] and
architecture framework [ietf-sfc-arch] of the working group.
Service function chains typically reside in a LAN segment which links
the mobile access network to the actual application platforms located
in the carrier's datacenters or somewhere else in the Internet.
Service function chains (SFC) ensure a fair distribution of network
resources according to agreed service policies, enhance the
performance of service delivery or take care of security and privacy.
SFCs may also include Value Added Services (VAS). Commonly, SFCs are
typical middle box based services.
General considerations and specific use cases are presented in this
document to demonstrate the different technical requirements of these
goals for service function chaining in mobile service provider
networks.
The specification of service function chaining for mobile networks
must take into account an interaction between service function chains
and the 3GPP Policy and Charging Control (PCC) environment.
