摘要： A method, system, apparatus and machine-readable medium for transmitting a packet through a network to convey network topology is provided. The method includes the step of generating at least one link state protocol data unit (LSP) with a first identifier until reaching a maximum sequence number in a sequence assigned to a network device, represented by the first identifier. The method further includes the step of modifying the first identifier to produce a second identifier. The method also includes the step of generating at least one LSP with the second identifier, and with a sequence number that is less than or equal to the maximum sequence number in the sequence. The system for transmitting a packet through a network, to convey network topology, comprises the means for performing the above-mentioned method steps.

摘要： 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.
