                  Huawei's GRE Tunnel Bonding Protocol
                 draft-zhang-gre-tunnel-bonding-05.txt

Abstract

   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 composing connection, 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. Publication of this
   document is to enable other developers to build interoperable
   implementations.
