Abstract

   The ability for a node to specify a forwarding path, other than the
   normal shortest path, that a particular packet will traverse,
   benefits a number of network functions. Source-based routing
   mechanisms have previously been specified for network protocols, but
   have not seen widespread adoption. In this context, the term
   'source' means 'the point at which the explicit route is imposed'.

   The objective of this document is to illustrate some use cases that
   provide the traffic engineering and the load balancing for mobile
   and transport network, applying segment routing.

1. Introduction

   In a mobile network, GTP is the protocol developed for tunneling and
   encapsulation of data units and control messages in GPRS. GTP for
   the Evolved 3GPP system comes in two variants, control and user
   plane. The control plane GTP-C handles the signaling, and it is
   needed in addition to the protocol for pure transfer of user related
   data, GTP-U. [3GPP TS 23.060]
