Abstract
A cluster compute server includes nodes coupled in a network topology via a fabric that source routes packets based on location identifiers assigned to the nodes, the location identifiers representing the locations in the network topology. Host interfaces at the nodes may be associated with link layer addresses that do not reflect the location identifier associated with the nodes. The nodes therefore implement locally cached link layer address translations that map link layer addresses to corresponding location identifiers in the network topology. In response to originating a packet directed to one of these host interfaces, the node accesses the local translation cache to obtain a link layer address translation for a destination link layer address of the packet. When a node experiences a cache miss, the node queries a management node to obtain the specified link layer address translation from a master translation table maintained by the management node.
