IP routing by an optical spectral-amplitude-coding CDMA network

An optical spectral-amplitude-coding CDMA network is proposed as a solution to the IP routing bottleneck in the global Internet. Its performance has been analysed for two different cases. For a given peak bit rate the network performance can be improved by reducing channel utilisation. However, when each user in the network has a fixed average bit rate, an optimal utilisation exists for the overall network performance. Analytical results clearly indicate that optical spectral-amplitude-coding CDMA technology may be a good candidate for the future IP backbone.
