Overlay multicast is expected to provide a realistic solution to the end-to-end multicast services before IP multicast is deployed all over the network. However, existing overlay multicast protocols are not standardized and many restrictions occur to provide many-to-many multicast services. This paper addresses the design and implementation of overlay multicast protocol for many to many multicast services.

    ABSTRACT: Current overlay multicast research focuses on its routing optimization fully considering its related network topology characteristics. To solve the multicast scalability issue, this paper proposed a novel multicast routing algorithm (S-MSPT) for the overlay network, inspired by the topology community detection in complex network theory. S-MSPT firstly mapped MSNs (Multicast Service Node) to a 2-dimension feature space. Then it divided MSNs into the communities and selected one MSN as the community center based on a clustering method. Finally the scheme applied a heuristic method to form a SPT-based hierarchical routing topology based on inter-community MSNs (composed by community centers and source MSN) and intra-community MSNs (rooted by its center) respectively. The experiments demonstrated that the proposed scheme is effective in the topology detection and the routing design with better scalable performance.

    ABSTRACT: Multipoint Video Conferencing (MVC) where multiple participants can be simultaneous sources of video requires low-delay, low packet loss and multipoint interaction synchronization. However, the synchronization issue is ignored by existing application-level multicast schemes and usually, it is addressed by a dedicated synchronizing controller at each peer. The controller needs to implement complicated time-consuming operations to synchronize multiple interactive media streams. Unlike the existing application-level multicast schemes, this paper introduces an idea that the synchronization problem is solved in the process of application-level multicast routing, without using the dedicated synchronizing controller. Furthermore, the low-delay multicast communication is achieved on base of the idea. The contributions of this paper include: 1.the concept that application-level multicast routing algorithms support multipoint interaction synchronization is defined by us; effective lowdelay multicast routing algorithm that supports multipoint interaction synchronization is proposed; 3.performance analysis of our algorithm and the existing similar algorithm is carried out. Finally, simulation experiments demonstrate our algorithm is correct and effective.

    ABSTRACT: Nowadays, a very useful platform is becoming widely used to deploy new services and applications in theInternet: the overlay networks. These networks create a virtual topology on top of existing ones with thepurpose of providing several different services such as file sharing or content delivery. This surveyfocuses on diverse research issues concerning overlay networks applicability and management strategiesrequired for emergent network environments. In this way, mobility, security, scalability, dependabilityand resource constraints are studied with regard to overlay networks. We finally discuss the evolution ofthese networks in order to satisfy new technological improvements.
