Abstract

Packet forwarding systems and methods allow packet-layer transparent, multi— stage packet forwarding among a set of network access points. Packet forwarding across networks utilizing the invention is directly controllable through the upper-layer nodes, e.g. routers, interconnected by such transparent packet forwarding networks. The systems and methods provide packet-layer routing, switching and forwarding look-up-table fee and transparent forwarding of label-encapsulated multi-protocol packet traffic among a set of routers. The invention enables flexible and efficient packet multicast and anycast capabilities along with real-time dynamic load balancing and fast packet-level traffic protection rerouting. The invention replaces the need for packet forwarding look-up-tables in a router interconnect network by a set of rules using which such network forwards packets directly based on their forwarding labels inserted in the packet headers by the routers exchanging packets through said network, thus simplifying network management and equipment implementation, and facilitating optimization of packet traffic flow across communications networks.
