Service Providers used to provide subscribers with separate access to their fixed networks and mobile networks. It has become desirable to bond these heterogeneous networks together to offer access service to subscribers; this service will provide increased access capacity and improved reliability.

                   Huawei's GRE Tunnel Bonding Protocol


   There is an emerging demand for solutions that provide redundancy and    load-sharing across wired and cellular links from a single Service    Provider, so that a single subscriber is provided with bonded access    to heterogeneous connections at the same time.

   In this document, GRE (Generic Routing Encapsulation) Tunnel Bonding    is specified as an enabling approach for bonded access to a wired and    a wireless network in customer premises, e.g., homes.  In GRE Tunnel    Bonding, two GRE tunnels, one per network connection, are set up and    bonded together to form a single GRE tunnel for a subscriber.    Compared with each subconnection, the bonded connections promise    increased access capacity and improved reliability.  The solution    described in this document is currently implemented by Huawei and    deployed by Deutsche Telekom AG.  This document will enable other    developers to build interoperable implementations.
