REDUCE SIZE OF IPV6 ROUTING TABLES BY USING A BYPASS TUNNEL

摘要

There are provided a system, a method and a computer program product for routing a data packet. A first router includes a routing table having address routes for routing packets of a first network communication protocol and address routes for routing packets of a second network communication protocol. A source router, adjacent to the first router, stores first network communication protocol addresses of routers adjacent to the first router. The system creates a network communication path from the source router to one or more adjacent routers for only routing the data packets according to a corresponding first network communication protocol address route. The system updates the routing table of the first router to remove the second network communication protocol address routes to the adjacent routers. The system routes the data packet according to the created network communication path and the updated routing table of the first router.

1. A method for routing a data packet in a communication network which operates according to network communication protocols, the method comprising:
routing the data packet to a target destination via a first router implementing a routing table having address routes for routing packets of a first network communication protocol and address routes for routing packets of a second network communication protocol; storing, in a source router adjacent to the first router, first network communication protocol addresses of routers adjacent to the first router; creating a network communication path, from the source router to one or more adjacent routers for only routing the data packets according to a corresponding first network communication protocol address route; detecting whether the address routes of the first router for routing packets of the second network communication protocol includes routes to any adjacent router; updating the routing table of the first router to remove the second network communication protocol address routes to the adjacent routers; and routing the data packet according to the created network communication path and the updated routing table of the first router.
