Abstract:
Measures, including methods, systems, non-transitory computer-readable storage mediums and computer programs for use in routing packet data. At a network switching device, a data packet is received from a device located upstream of the network switching device. The received data packet comprises routing data associated with a routing decision which has been taken for the data packet upstream of the network switching device. The routing data comprises an abstract media access control (MAC) address corresponding to a next hop destination for the data packet located downstream of the network switching device. At the network switching device, the abstract MAC address in the data packet is replaced with a real MAC address of the next hop downstream destination. At the network switching device, the data packet is forwarded towards the next hop downstream destination.

Claim (Index 14):
A non-transitory computer-readable storage medium comprising computer-executable instructions, which, when executed by a processor, cause a computing device to perform a method of routing packet data, the method comprising:\n at a network switching device, receiving a data packet from a device located upstream of the network switching device, wherein the upstream device comprises: a data center router, or a data host in a content distribution network comprising a plurality of data hosts, wherein, prior to being received by the network switching device, the received data packet has been tagged by the upstream device such that it comprises routing data associated with a routing decision which has been taken for the data packet upstream of the network switching device by the upstream device, wherein the routing data comprises an abstract media access control (MAC) address corresponding to a next hop destination for the data packet located downstream of the network switching device; and wherein the abstract MAC address acts as an indirect reference address to enable data packet tagging; at the network switching device, matching the abstract MAC address with a real MAC address of the next hop downstream destination, wherein the network switching device stores a mapping between the abstract MAC address and the real MAC address of the next hop downstream destination, and wherein the real MAC address corresponds to a physical address of the next hop downstream destination; and at the network switching device, replacing the abstract MAC address in the data packet with the real MAC address of the next hop downstream destination; and at the network switching device, forwarding the data packet towards the next hop downstream destination.
