Abstract

This paper explores and proposes the use of open programmable router technologies to achieve dynamic configuration, adaptation and management of network entities. The objective is to provide highly dynamic and flexible edge router technology to support the interconnection between emerging short range wireless technologies such as WPANs and IP based networks. To improve current software based edge router designs, the paper merges the Click framework (an open source software architecture for the forwarding plane) and the Forwarding and Control Element Separation (ForCES) principle. The proposed architecture is implemented on a real testbed based on standard PCs and open source operating systems. Results on achievable performance using these software based solutions and Click are reported. The impact on traffic flows and applications in terms of packet losses and delays is evaluated.
