Scalable resilience for Software-Defined Networking using Loop-Free Alternates with loop detection

In this paper we propose a novel resilience scheme for OpenFlow-based Software-Defined Networking (SDN). To forward packets in line speed, OpenFlow switches store their flow tables in expensive, limited TCAM due to which the stored tables cannot be large.Most resilience mechanisms require additional entries thus the implementation in OpenFlow may quickly exceed the available TCAM.

Link adaptation strategy for healthcare application on IEEE 802.15.4 WPANs

The signaling of the healthcare applications needs the error performance and the multiple data rate for different target rates of various bio-signals. In this paper, we propose a link adaptation strategy on the multi-rate modulation set for IEEE 802.15.4 wireless personal area networks (WPANs). The protocol stack made by the network simulator OPNET is used […]

Overlapping community structure detection in multi-online social networks

Overlapping community structures can reflect the fact that an individual can belong to more than one community, especially the individuals in social networks. It is important to detect overlapping community structures in online social networks. In this paper, an overlapping community detection algorithm is proposed for online social networks. Different from previous works, this algorithm can be […]

SCLP: Segment-oriented Connection-less Protocol for high-performance software tunneling in datacenter networks

The notion of Software-Defined Networking (SDN) has already been introduced into cloud datacenter networks for provisioning virtual network environment. Network virtualization of today is generally achieved by L2-in-L3 tunneling protocols like VXLAN (Virtual eXtensible LAN) and NVGRE (Network Virtualization using Generic Routing Encapsulation) in public cloud datacenters. Some leading production packages for network virtualization have adopted […]
