MAINTAINING CACHES OF OBJECT LOCATION INFORMATION IN GATEWAY COMPUTING DEVICES USING MULTICAST MESSAGES

Example embodiments relate to maintaining caches of object location information in gateway computing devices using multicast messages. In example embodiments, upon updating a cache with an object identifier and a corresponding object location, a gateway computing device may transmit an update message using a simple multicast transport protocol to a plurality of other gateway computing devices. In contrast, upon deleting an object from a cache, the gateway computing device may transmit a delete message using a reliable multicast transport protocol to the plurality of other gateway computing devices.
