Abstract

It is anticipated that future core networks may evolve to Optical Cross-Connect (OXC) based architectures where switching is carried out at the granularity of wavelength-based circuits. While the switch fabric is an important component of an OXC, the number of ports is typically a more significant contributor to its cost. Reducing the number of ports (or number of wavelengths per link) will also result in lower transmission-systems costs. We investigate the effect of incorporating some packet switching functionality in the OXC and try to quantify the bandwidth savings that can be gained by doing so, under certain assumptions about the network and the traffic characteristcs. Results show that taffic grooming and statistical multiplexing gain, which are introduced by the packet handling functionality, lead to better channel utilization. This can result in lowering the number of channels and ports and in reducing the OXC size and cost.
