title: Providing Resilience in Communications Networks
publication_year: 2009
abstract: The purpose of the Resilient Networks Project at Simula is to provide resilience in communications networks with cost-efficient approaches. In particular, we identify and solve challenges for both Internet and wireless networks. In the Internet context, we focus on scalable solutions for maintaining network operations during failures or other challenging scenarios. This includes providing fast recovery from component failures, increasing robustness to failures and traffic fluctuations by spreading traffic on multiple paths, and investigating the scalability limitations of the current interdomain routing protocol BGP. Wireless resilience is highly dependent on a specific kind of wireless system and it is closely related to Quality-of-Service (QoS) provisioning. For this, we have investigated the resilience in resource-constrained sensor networks and QoS in OFDM-based wireless networks. It has been shown that the proposed strategies are able to substantially enhance network throughput and increase service reliability. In this chapter, we give an overview of the recent activities in the project, and briefly discuss future plans. Further technical details can be found in our journal and conference papers.
