GRE (Generic Routing Encapsulation) specifies a protocol for the encapsulation of an arbitrary protocol over another arbitrary network layer protocol. This document describes extensions to manage multiple GRE tunnels over multiple access lines to one home network with the purpose to present a novel architecture using Hybrid Access (HA) networks. HA is designed to bundle multiple access technologies, e.g. fixed access and wireless access to one Internet connection. This enables higher bandwidth for end customers. The document describes the Hybrid Access network architecture and th extensions for GRE which are necessary to implement the HA architecture.
