ABSTRACT:
Methods, systems, and apparatuses for transmitting link state packet (LSP) through a network are provided. The method includes dividing the LSP into LSP fragments having respective fragment numbers, transmitting the LSP fragments repetitively through the network, identifying at least one LSP fragment that is updated while the LSP fragments are being transmitted, and retransmitting the identified LSP fragments. The transmitted updated LSP is used for processing the Shortest Path First algorithm to identify accurately the shortest path that can be used to establish communication in the network.
