Method and system for routing packets over parallel links between neighbor nodes

摘要

In a communications network formed by routers interconnected by parallel component links, hello packets are exchanged between neighbor routers at intervals to know each other in a learning process and update their status. Each router groups the parallel component links into a bundled link according to a link-up or link-down request and produces a first database mapping the relationships between component links and bundled links. The router performs routing calculations according to a link state routing algorithm using the bundled link as a unit of transmission medium and produces a second database mapping relationships between destination addresses and bundled links. The first and second databases are downloaded to interface units connected to the parallel component links. When a data packet is received, the databases are used for translating the header of the data packet for allowing it to be routed through a switch for transmission.
