Abstract
Reliable address discovery cache techniques are described. In an implementation, a reliable communication channel is established for control messages related to address resolution in a network. The communication channel is employed for communication of messages for internet protocol (IP) address acquisition, release, and mapping staleness between clients (e.g., nodes or endpoints) in the network and a cache manager component configured to maintain and update an address map for the clients. The cache manager component may also be configured to send directed messages via the communication channel to propagate changes in the mapping to the clients. Further, clients may provide explicit notifications regarding address release and staleness to the cache manager component to facilitate updating of the address map. In this way, a reliable and up-to-date address map is maintained and the amount of broadcast discovery messages and bandwidth consumed overall for address discovery operations may be reduced.
