This paper presents FlexForward, an approach for dynamically manage SDN data plane forwarding mechanisms. This feature leverages SDN flexibility in two aspects: (i) it provides a new management method, in which topological infrastructure requirements are satisfied by the most appropriate forwarding mechanism, residing in each managed network element; (ii) further decoupling between control and data...
The authors propose an interconnection topology suited to server-centric networks based on Twin graphs. The topology exploits graph theory to cost-effectively improve network scalability and resilience. The authors discuss datacenter network topology by comparing Twin interconnection topologies to different datacenter topologies (that is, Fat Tree, BCube, DCell, and Hypercube). Their results show...
Photonic packet switching faces a major challenge in providing low packet loss probability under the constraint of shallow optical buffer depth. Although improvements have been gained by exploiting the wavelength domain through the use of WDM and wavelength conversion, performance enhancement through the use of packet priorities have yet to be investigated. This paper discusses the relationship between...
