1. A network node comprising:
one or more processors; and
one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause the network node to perform link state flooding operations to a receiving node, the link state flooding operations comprising:
determine a current transmit rate that Link State Protocol Data Units (LSPs) are being transmitted from the network node to the receiving node;
determine an LSP acknowledgment rate, the LSP acknowledgment rate indicating a rate at which a plurality of LSP acknowledgments are received at the network node from the receiving node;
determine a new transmit rate based on the current transmit rate and the LSP acknowledgment rate; and
transmit a plurality of LSPs from the network node to the receiving node using the new transmit rate.
