Abstract:

The integrated routing algorithm in IP over WDM networks under the self-similar traffic is studied, and a new integrated on-line routing algorithm, min_influence algorithm, is proposed. It can model the state of the whole network more accurately after assigning resource than other algorithms, and facilitate the distribution of
network resource more reasonably, which consequently improves the Network performance. Extensive simulations in three respective network topologies show that min_influence algorithm performs better in terms of connection blocking probability (CBP) and bandwidth blocking ratio (BBR) than other existing approaches under the parameters of self-similar traffic(hurst, mean and variance).

Key words: IP over WDM, integrated routing, self-similar traffic, network performance
