MOSAIC constructs new overlay networks with desired characteristics by composing existing overlays with subsets of those attributes. Thus, MOSAIC overcomes the problem of multiple network infrastructures that are partial solutions, while preserving deployability. Composition of control and/or data planes is possible in the system. MOSAIC overlays are specified in Mozlog, a declarative language ...

Network overlay construction has found many applications in today’s Internet, such as P2P networks [1][2], end-host multicast [3][4], and network security [5]. Many researchers have proposed solutions to building an overlay network among a given group of end-hosts. The usual overlay construction assumes two-way network communication— each host can initiate connections to and accept requests fro...

The literature contains propositions for the use of overlay networks to supplement the normal IP routing functions with higher-level information in order to improve aspects of network behavior. We consider the use of such an overlay to optimize the end-to-end behavior of some special traffic flows. Measurements are used both to construct the virtual links of the overlay and to establish the lin...

Advancement in wireless infrastructure for data access through third generation wireless and wi-fi technologies makes it possible to use mobile devices for various activities and transactions involving Internet. Several proposals have been made to provide data nearer to user. In this paper, we propose multiple overlay networks to provide a network infrastructure to support quick and efficient m...

An overlay-based IPTV content delivery is a relatively new type of content delivery in which user devices such as set-top boxes are connected with one another to form a dynamic, virtual delivery path. In the network, each overlay node forwards data, which one has received from another overlay node. To ensure security of the IPTV content delivered through the overlay, we propose a new key manage...

Overlay networks are expected to operate in hostile environments where node and link failures are commonplace. One way to make overlay networks robust is to design self-stabilizing overlay networks, i.e., overlay networks that can handle node and link failures without any external supervision. In this paper, we first describe a simple framework, which we call the Transitive Closure Framework (T...

In the past few years, overlay networks have received much attention but there has been little study on the “interaction” of multiple, co-existing overlays on top of a physical network. In addition to previously introduced concept of overlay routing strategy such as selfish routing, we introduce a new strategy called “overlay optimal routing”. Under this routing policy, the overlay seeks to min...

Overlay networks have been used for adding and enhancing functionality to the end-users without requiring modifications in the Internet core mechanisms. Overlay networks have been used for a variety of popular applications including routing, file sharing, content distribution, and server deployment. Previous work has focused on devising practical neighbor selection heuristics under the assumpti...

Dynamic overlay routing has been proposed as a way to enhance the reliability and performance of IP networks. The major premise is that overlay routing can bypass congestion, transient outages, or suboptimal paths, by forwarding traffic through one or more intermediate overlay nodes. In this paper, we perform an extensive simulation study to investigate the performance of dynamic overlay routin...
