Bandwidth-efficiency-oriented topology optimization for integrated switching systems based on circulant graphs

摘要

This work studies a topology optimization problem by leveraging a regular network topology-circulant graph. The result of the topology optimization is applied to the design of the integration network for modern integrated switching systems (ISSs), which integrate individual switching devices together to boost switching capacity and to reduce network management complexity. The target of the optimization is to maximize bandwidth efficiency on the integration links and hence to maximize the ISS capacity to accommodate traffic. This eventually translates to minimizing the average inter-node hop distance within the ISS.
