Software Defined Networking (SDN) is a novel approach to building computer networks. Improved flexibility, simplified management and cost reduction promised by SDN makes many see it as the future of networking. The main insight of SDN is the separation of ...
Software packet-processing platforms- - network devices running on general-purpose servers-- are emerging as a compelling alternative to the traditional high-end switches and routers running on specialized hardware. Their promise is to enable the fast dep ...
To become a credible alternative to specialized hardware, general-purpose networking needs to offer not only flexibility, but also predictable performance. Recent projects have demonstrated that general-purpose multicore hardware is capable of high-perform ...
Software routers promise to enable the fast deployment of new, sophisticated kinds of packet processing without the need to buy and deploy expensive new equipment. The challenge is offering such programmability while at the same time achieving a competitiv ...
We consider the problem of rate-distortion (RD) optimized media streaming in unstructured peer-to-peer (P2P) overlay networks. We formulate the aforementioned problem as a distributed rate allocation problem. To solve the problem for all the participating ...
Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...
In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multi-hop communication. In recent years, incentive mechanism ...
Some forms of ad-hoc networks need to operate in extremely performance- challenged environments where end-to-end connectivity is rare. Such environments can be found for example in very sparse mobile networks where nodes ”meet” only occasionally and are ab ...
