Developing layer 3 switch with 100 Gbps optical packet interface

We newly developed a layer 3 switch prototype that has one 100 Gbps optical packet interface and twelve 10 GbE interfaces. This is a gateway node to the optical packet switched network. While similar nodes made by the authors just have conversion capability from/to Ethernet frames to/from optical packets, this switch provides full layer 3 switching capability among the 13 ports, namely, packets incoming from any input port can be sent to any output port via destination IP address lookup. We show 12,000 prefixes are looked-up and 4,000 destination addresses of optical packets are added as a result of the lookup. We also show that the layer 3 switch is connected to the access line to the Internet.
