The link-state advertisement (LSA) is a basic communication means of the OSPF routing protocol for the Internet Protocol (IP). It communicates the router's local routing topology to all other local routers in the same OSPF area. OSPF is designed for scalability, so some LSAs are not flooded out on all interfaces, but only on those that belong to the appropriate area. In this way detailed information can be kept localized, while summary information is flooded to the rest of the network. The original IPv4-only OSPFv2 and the newer IPv6-compatible OSPFv3 have broadly similar LSA types.
Method and system for transmitting link state update packets
There is provided a method and system for transmitting link state update (LSU) packets containing new link state advertisements (LSAs). In some embodiments, the transmission of the LSU packet is based on the priority of the received LSAs and the status of a pacing timer. In the same or other embodiments, a control stack is generated for tracking the number of unacknowledged LSAs previously transmitted and the interface transmit time interval is adjusted based on the control stack.
