Pivot-based fast automatic address configuration for data center network

Encoding topology information into logical addresses is a new trend in data center network (DCN) as it can help to improve the scalability and routing efficiency. Regretfully, to configure large-scale data center manually is not only time-consuming but also error-prone. Because of this, research in auto-configuration becomes getting more attention. Previous works in auto-configuration generally neglect the properties of given topology and cause high computational complexity. In this paper, we propose a new auto-configuration algorithm called Pivot-based Fast Automatic Configuration (PFAC). Leveraging properties of the given data center network topology, PFAC can assign addresses to physical devices in the data center automatically and efficiently. The experiments show that the processing time of PFAC is reduced by about 30% compared to previous works.
