Santa Cruz researchers have demonstrated a 100 Gbps stream running reverse-multiplexed over 10× 10 Gbps channels from Tampa to Houston. A special packet-multiplexing scheme from UCSC allowed retention of packet ordering, even as flows are multiplexed across channels.
A number of groups were involved:
|Infinera [PR]||DWDM & project management|
|Internet 2 [alt]||methodology & support|
|Level 3||transmission paths|
|UCSC||MAC & packet re-sequencing|
Note that this was not a 100 Gbps transmission interface; but consider that local interfaces faster than 10 Gbps (e.g. STM-256 / STS-768 at 40 Gbps) do exist and traffic could conceivably be generated at this rate for transmission over long distance. The LHC leads the way!
