Novel Layer-3 IP Packet Switching between 10 Gbps Ethernet and 80 Gbps Optical Packet-Switched Networks

We develop novel layer-3 (L3) Internet protocol (IP) packet switches to connect 80 Gbps WDM-based optical packet switching (OPS) networks with 10 Gbps Ethernet (10GbE). A L3 switch, which is the ingress edge node of the OPS network, generates an optical label according to a look-up table and the destination address of an IP packet, and then encapsulates the almost 10 Gbps IP packet into an 80 Gbps (8-wavelength x 10 Gbps) optical packet Another type of L3 switch, which is the egress edge node of the OPS network, decapsulates the IP packet from the optical packet and generates a lOGbE frame accommodating the IP packet according to a look-up table. We achieve the transmission of 7.2-Gbps IP packets throughput with a packet loss rate under 10^-6 and demonstrate smooth UDP/IP-based 3D high-definition television (HDTV) video-streaming via the L3 switches and 80 Gbps WDM-based OPS system.
