“…Reducing the required bandwidth and providing minimum network stress are critical when the network supports a large number of clients. The overlay multicast [4–7] has been introduced for IP multicast, but it still has some drawbacks when deployed over the Internet.…”

An important problem in many P2P applications is how to efficiently disseminate massive contents from multiple sources to multiple receivers on the Internet. A successful model used for analyzing this problem is a graph that consisted of nodes and edges, with a capacity assigned to each edge. However, a scheme that can flexibly deal with the extreme network dynamic is required in order to realize the massive contents streaming service, because P2P networks are mostly formed in random fashion without good control of their topology. In this paper, we design and implement a scheme for the problem of efficient massive contents dissemination in a sensor smart network system.

Abstract. In the present paper, we designed a specific router which provides the required level of QoS over NGN(Next Generation Network) by controlling data flows. We called this router QoS-Adaptive router, which consists of two parts, a legacy routing part and a QoS guarantee routing part. In order to provide differentiated services, QoS-Adaptive router enables data taking broad bandwidth or data requiring high-level QoS to be processed immediately and not to be affected by other services. And, we used the definition of flow for perflow management, and assigned new service types to the flow label field of IPv6 header so as to provide differentiated services according to the packet type. By doing this, we designed a distinguishing mechanism in order to adapt to NGN that concentrates upon QoS. We built not only a small network to test QoS-Adaptive router but also a simulation environment called OMNeT++, and we could verify the performance of QoS-Adaptive router supporting QoS based on subscriber and service levels.
