Abstract
We developed novel network interfaces, for example 10 Gbit Ethernet
to 80 Gbit/s optical-packet (10 GbitE–80 GbitOP) or 80 Gbit/s optical-packet
to 10 Gbit Ethernet (80 GbitOP–10 GbitE) converters (collectively called
as 10 GbitE/80 GbitOP converters), to connect optical packet switching (OPS)
networks with IP technology-based networks. By using newly developed arrayed
burst-mode optical packet transmitters/receivers together, the 10 GbitE–80
GbitOP converter at the ingress edge node of the OPS network encapsulates
an IP packet into an $80(8\lambda\times
10)\ {\rm Gbit/s}$ dense wavelength division multiplexing
(DWDM)-based optical packets and generates an optical label based on a lookup
table and the destination addresses of the IP packet. The 80 GbitOP–10
GbitE converter at the egress edge node decapsulates the IP packet from the
optical packet and generates a 10 GbitE frame accommodating the IP packet
according to a lookup table. By using these network interface devices and
OPS system based on multiple optical label processing, we achieved, for the
first time, 74-km single-mode fiber transmission, switching, and buffering
of $80(8\lambda\times 10)\
{\rm Gbit/s}$ DWDM-based optical packets encapsulating almost
10 Gbit/s IP packets with error-free operation (IP packet loss rate $< 10^{-6}$).
