Abstract

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.

First claim

I claim:

1. A gateway computing device for maintaining a cache of object location information, the gateway computing device comprising:
a storage medium to maintain a cache of object location information of objects stored in a storage system; and
a processor to:
receive a request to store a first object in the storage system;
forward the request to the storage system to store the first object;
in response to the first object being stored in the storage system, create a new…
