Abstract
This paper presents a new technique for constructing IP over photonic systems. The use of label switching is assumed in the
IP routers, while a new routing architecture is introduced to transport IP packets across an optical backbone network. The architecture is based on a two-level TDMA structure with wavelength division multiplexing (WDM). Many IP-based network applications such as high-resolution image, distributed database, and real-time video/audio service, generally require high-speed transmissions in WAN/LAN. The network traffic in these applications usually exhibits traffic locality. As a result, traditional TDMA is no longer appropriate for such traffic because of inefficiency. Consequently, based on the traffic parameters such as locality and loading, an architecture named a PG (Partition-Group) Network is proposed. Furthermore, the interleaved control slot (ICS) with cross-group section (CGS) or non-cross-group section (NCGS) for reducing collisions is also presented. The slot reuse can be easily achieved by using the ICS scheme and the slot utilization of the network can be
improved within the high traffic locality.
