In this paper the authors introduce the Axon, a network device that employs source-routed Ethernet to improve the scalability of local-area networks. Axons provide transparent compatibility with unmodified hosts, which see the network as a single switched Ethernet segment. Prototypes of the Axon have been implemented on the NetFPGA platform and used to demonstrate the performance and backwards compatibility of source-routed Ethernet. Future paper will combine prototype Axons with simulated Axons to evaluate network scalability for up to one million hosts.
