P. Toliver et al., Routing of 100 Gb/s words in a packet-switched optical networking demonstration (POND) node, J LIGHTW T, 16(12), 1998, pp. 2169-2180
This paper presents the design and experimental results of an optical packe
t-switching testbed capable of performing message routing with single wavel
ength time division multiplexed (TDM) packet bit rates as high as 100 Gb/s,
The physical topology of the packet-switched optical networking demonstrat
ion (POND) node is based on an eight-node ShuffleNet architecture. The key
enabling technologies required to implement the node such as ultrafast pack
et generation, high-speed packet demultiplexing, and efficient packet routi
ng schemes are described in detail, The routing approach taken is a hybrid
implementation in which the packet data is maintained purely in the optical
domain from source to destination whereas control information is read from
the packet header at each node and converted to the electrical domain for
an efficient means of implementing routing control. The technologies develo
ped for the interconnection network presented in this paper can be applied
to larger metropolitan and wide area networks as well.
