Huawei's GRE Tunnel Bonding Protocol
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 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.
