LINEAR NETWORK CODING REPLACES OPTIMAL ROUTING IN ETHERNET- OVER-OPTICAL NETWORKS
Abstract: This talk sets the goal to tackle the challenges associated with network capacity upscaling by unifying the research on multipath routing and parallel end-systems on a case study of Ethernet-over-optical networks. In high-speed Ethernet systems today, data can be parallelized and spatially distributed as multiple flows, and sent over multiple optical channels. Up to now, optimal routing was necessary to address the issue of inter-lane skew in Ethernet-over-optical networks, criti cal to the Ethernet receiver design. We postulate (and prove) that when multi-lane Ethernet systems deploy random linear network coding (LNC) prior to the optical transmission, the Ethernet receivers can use smaller buffers, — a cost-critical feature in 100Gb/s systems, while the network management systems can relax the condition on routing optimality, and thus significantly simplify the optical path setup, — which is a challenge today. We will present a few early-stage studies of high-speed Ethernet parallel transmission over various optical network technologies, discuss the associated fundamental research challenges as well as emerging application scenarios.
