The demand for high-bandwidth media streaming over the Internet is growing. For large groups of receivers, media streaming places a heavy burden on the network. IP Multicast can alleviate this problem, but it is not widely deployed. In recent years, application layer multicast and overlay multicast have been proposed as alternatives. However, there are still concerns about the efficiency, scalability and deployment of these architectures.
In this thesis, a novel application layer multicast approach, called the Dynamic Mesh-based Overlay Multicast Protocol (DMMP), is evaluated. DMMP establishes an overlay network core consisting of super nodes, which are end-hosts with particularly high capacities. Each super node manages a cluster of non-super nodes. We use network simulations to analyze the performance of DMMP. For that purpose, we have implemented a DMMP module in OverSim. OverSim is an overlay network simulation framework based on OMNeT++.
We compare DMMP with NICE, a well-known application layer multicast protocol, that is claimed to achieve low link stress and low control overhead. We experiment with groups of up to 2048 members. Our results indicate that DMMP can achieve comparable service quality with less control overhead, and that DMMP has the potential to scale to a high number of receivers.

Multicasting can provide an efficient way of delivering data from a sender to a group of receivers. It has received much attention over the past decade because of an increasing demand for group communication applications such as multimedia streaming. However, native IP multicast has not become widespread largely due to its technical and operational issues. To overcome these obstacles of deployment, various application layer and overlay multicast approaches have been proposed. Compared with IP multicast, they provide a new way of handling multicast without upgrading the infrastructure in a large scale. Nevertheless, they introduce a number of challenges and are still plagued with concerns on scalability, heterogeneity and dynamic performance. In this paper we propose a new protocol framework for addressing these issues, so-called the Dynamic Mesh-based Overlay Multicast Protocol or DMMP, which intends to provide an efficient and resilient multicast support by dynamically managing an overlay core comprised of end hosts. Moreover, DMMP can be used for media streaming which is contracted by a limited resource in stream supplying entities and requires good scalability and reliability. Initial analysis shows that DMMP has the potential to efficiently deliver multicast services for large groups.

This document describes a Dynamic Mesh-based overlay Multicast Protocol (DMMP) to support multicast data delivery applications without relying on classic IP multicast, including multicast group management, overlay hierarchy establishment, multicast tree construction and data forwarding scheme from the source to a number of receivers. The DMMP framework builds on control plane functions which dynamically manage an overlay core and a multicast tree layer. The key idea is a number of end hosts self-organize into an overlay mesh, and dynamically maintain such a mesh. Based on the constructed mesh, some core-based clusters are built with capacity-aware trees inside. Then, a multicast tree consisting of DMMP-aware end hosts (and/or specific routers) is built on the top of the overlay core for the efficient delivery of the multicast data.

Although more analysis and evaluation is necessary, this paper sheds light on several identified design issues with DMMP and initially analyzes its performance.
