GONE: A Relisient, DoS-Limiting Infrastructure Overlay Architecture We propose an overlay network architecture by introducing a set of generic functions in network edges and end hosts. We conjecture that the network edge constitutes a major source of DoS, resilience and mobility issues to the network, and propose a new solution to this problem, namely the General Internet Signaling Transport (GIST) Overlay Networking Extension, or GONE. The basic idea of GONE is to create a half-permanent overlay mesh consisting of GONE-enabled edge routers, which employs capability-based DoS prevention and forwards end-to-end user traffic using the GIST messaging associations. It intends to offer a number of advantages for upper layer end-to-end applications, including intrinsic provisioning of resilience and DoS prevention in a dynamic and nomadic environment. See more details for the GONE concept in the paper appeared in ACM NOSSDAV 2006.
Network Virtualization
Recently, several “Future Internet” initiatives
have started in Europe, the US and Asia, offering the exciting opportunity to
design new approaches to supporting richer network services in a variety of
scenarios and environments, such as middleboxes, IPv4-v6 interworking, p2p, wireless networks and
other services. These research efforts may eventually lead to an internetwork
architecture with the support of overlay and network virtualization
significantly more flexible features than the traditional network architecture and services. In this scope we are organizing an Overlay and Network Virtualization Workshop at KiVS 2009.
We are currently looking at two issues with network virtualization: - virtualizing real networking nodes for experimenting future Internet ideas research - virtualzing wireless networking resources so that the same physical resources could be used for a multitude of applications and services. In this aspect we are involved in a Mobile P2P workshop at IWCMC 2009. Peer-to-Peer Networking and Traffic Localization In this field we are studying the following issues among the others: - Peer-to-Peer SIP (P2PSIP). We implemented one of the early P2PSIP prototype in both desktop PCs and mobile devices and evaluated its performance on the PlanetLab global testbed. - Location-aware peer-to-peer management mechanism. We measured the P2P VoD Joost software for more than 5 months from which we inferred several weaknesses of today's techniques. We propose a mesh-based peer-to-peer overlay architectures, including its enhancements and conduct extensive evaluations on our proposal. - Interest-based traffic optimization.
