Overlay networks are becoming widely used for delivering content, since they provide effective and reliable services that are not otherwise available. However, overlay management systems face the challenges of increased complexity and heterogeneity due to the numerous entities that are involved in realizing overlay services. We believe that autonomic management is a key solution for dealing wit...

Current research in peer to peer systems is lacking appropriate environments for simulation and experimentation of large scale overlay services. This has led to a plethora of custom made simulators that waste development resources and hinder fair comparisons between different approaches. In this paper we present a new simulation / experimentation framework for large scale overlay services with ...

Inadequate end-to-end Quality of Service (QoS) and resilience support still exists across the Internet as it is difficult to achieve cooperation between the Autonomous Systems (AS) that are operated independently by Internet Service Providers (ISP). The use of an Overlay Network (ON) deployed on top of the Internet is viewed as one of the effective strategies to provide some measure of service ...

This deliverable summarizes our recent research results on the topic of service overlay networks, an innovative concept for end-to-end QoS assurance. It reports the research contributions we have achieved during the last period, including i) a technical overview and evaluations of existing architectures for end-to-end QoS with special focus on the overlay network solution, ii) our scientific co...

Peer-to-peer overlays constitute a new approach for delivering wide-area network and application services. The systems typically use a combination of self-organisation and cooperation with other peers to determine the peer’s role and performance in the overlay. Few overlays support external management mechanisms, which are the basis for overlay operators to provide specified service levels. We ...

A P2P system based on super-peer overlay shows good features of combining both advantages of hybrid and pure P2P systems. Most P2P applications being developed are based on the overlay networks composed of super-peers. Super-peer is a special peer acting as a server to a cluster of client peers. Selecting super-peers and constructing a super-peer overlay for clustering client peers are importan...

REsource LOcation And Discovery (RELOAD) is a peer-to-peer signaling protocol that can be used to maintain an overlay network, and to store data in and retrieve data from the overlay. RELOAD is currently being standardized in the Internet Engineering Task Force (IETF). The main application using RELOAD is Peer-to-Peer Session Initiation Protocol (P2PSIP). In this paper, we study the performance...

Different industrial decision makers and managers in our country, try to select and organize locations for aggregating industrial units, estates and areas with respect to land use planning visions and industrial development strategies. In this regard, considering large quantity of the input data and diverse criteria affecting this application, it is complicated and difficult to optimally make d...
