ABSTRACT:
Link-based source routing may be implemented using generic framing protocol (GFP) to enable GFP frames to contain a switching context that will allow them to be forwarded on a network without requiring state information to be distributed to interior network elements on the network. Source routes may be computed from network topography information obtained using OSPF or ISIS. An extension header type is added to the GFP frames to signal to the network elements that the GFP frame contains a link-based source route. The source route contains a vector of tunnel IDs and a pointer to the current hop, to enable the current tunnel ID to be determined. The tunnel IDs have local significance only, and hence state information is not required to be distributed on the network. A return route may be built by index substitution as the frame traverses the network.
