Link performance monitoring is a common task required by different overlay networks. Current overlays typically let each node monitor links by itself, which is not scalable for large networks. Earlier improvement proposals either use a centralized approach or sacrifice measurement accuracy. This paper proposes MONET, a distributed overlay monitoring technique. Based on the proposed X-Set concep...

Overlay networks have emerged as a fundamental technique for efficient data dissemination. Current overlay construction techniques typically face a number of limitations, including: i) limited scalability because of reliance upon global knowledge, and ii) performance characteristics targeting the requirements of a particular class of applications. In this paper, we propose dynamically organizin...

Due to the growing demand for high definition music and video content, an overlay multicasting providing live streaming services has been gaining popularity over last years. In this paper, we focus on applying the overlay multicasting for delivering of critical data that require to be transmitted safely, intact and with as little delay as possible, e.g., financial data, software security patche...

Multicast can be done on link layer, IP layer, and application layer respectively. The application level overlay multicast is easier to deploy as compared to non overlay multicast but at the cost of efficiency. However, the utilization of these approaches is limited by current Internet architecture. Overlay and non overlay integrated solution have not yet been proposed for hybrid networks. In t...

This paper addresses the problem of building scalable semantic overlay networks. Our approach follows the principle of data independence by separating a logical layer, the semantic overlay for managing and mapping data and metadata schemas, from a physical layer consisting of a structured peer-to-peer overlay network for efficient routing of messages. The physical layer is used to implement var...

In this paper, we address the challenge of overlay topology design by considering which overlay topology best minimizes cost function, taking into account overlay link creation cost and routing cost. First, we formulate the problem as Integer Linear Programming (ILP) given a traffic matrix and assuming cooperative behavior of nodes. Then, we propose some heuristics to find near-optimal overlay ...
