METHOD OF PERFORMING ROUTE LOOKUP FOR ROUTING DATA IN NETWORK ROUTER AND SYSTEM THEREOF

摘要

Present disclosure relates to a method and system (100) for performing route look-up for routing data in a network router. First router shares a direct index with one or more neighboring routers. A second router of the one or more neighboring routers encodes the direct index as part of a packet header and sends the packet header with encoded direct index to a next hop router of the one or more neighboring routers. The next hop router then decodes the encoded direct index and locates one or more route look-up results based on the decoded direct index. In an embodiment, an outgoing interface index of a second hop router is added to a packet header of a data packet at the first router. Further, the data packet is forwarded to one or more hop routers based on the outgoing interface index by the second hop router.
