Multicast Services

Application Layer Multicast (ALM) is considered as an attractive approach for implementing wide area multicast services. In ALM, multicast functionality is implemented at the edge instead of the core network (routers). As opposed to network-layer multicast, application layer multicast requires no infrastructure support and can be easily deployed in the Internet. In this paper, we propose a new efficient and scalable model for optimizing application layer multicast using HPM architecture (HPM: A novel hierarchical Peer-to-Peer model for lookup acceleration with provision of physical proximity). This approach benefits from P2P properties and characteristics. In this contribution, we consider our optimized tree construction algorithm simultaneously for each ring of HPM. The global tree construction algorithm is composed of two steps. In the first step, we construct a sub-tree for each ring; the second step is to build a global tree using sub sets of adjacent rings in HPM architecture. The proposed model inherits from main P2P attributes such as: scalability, fault tolerance characterized HPM. Preliminarily performance evaluations show that results are globally satisfactory, the depth of the resulting multicast tree is optimized.

Both Mobile Ad hoc Networks (MANETs) and Peer-to-Peer (P2P) networks are decentralized self-organizing networks with a dynamic topology, used to route queries in a distributed environment. However, whilst MANETs are composed of resource-constrained devices susceptible to faults, P2P networks are popular for their resilience and fault-tolerance. This makes P2P networks the ideal data sharing system for MANETs. This chapter focuses on the integration of these networks. More specifically, the authors evaluate routing strategies of both the network layer and the application layer. Their results indicate that the performance of the protocols depends greatly on the environment and point out the need for new approaches.

In this paper we propose a deployable approach to improving QoS by using a generic, extendable, overlay architecture; the Generalized Application Layer Overlay (GALO). The goals of this work are to 1) create an overlay architecture which allows us to sample specific path quality metrics among different paths; 2) utilize the proposed overlay architecture in order to implement our proposed QoS-based routing schemes, Application Layer Switching (ALSW) and Application Layer Striping (ALST). Perhaps the most significant contribution of this research is that we are able to achieve better than best-effort QoS without modifying intermediate nodes (i.e., routers), thus encouraging immediate deployment. Additionally, this research is performed on an actual wide area network (WAN) testbed, comprised of universities across the nation. Also, we assemble this architecture as a peer-to-peer framework, encouraging collaborating individuals with average workstations to improve the QoS of their traffic.

Despite the fact that global multicast is still not possible in today's Internet, many local networks are already multicast-capable (the so-called multicast “islands”). However, most application-layer multicast (ALM) protocols for streaming have not taken advantage of the underlying IP multicast capability. As IP multicast is more efficient, it would be beneficial if ALM can take advantage of such capability in building overlay trees. In this paper, we propose a fully distributed protocol called scalable island multicast (SIM), which effectively integrates IP multicast and ALM. Hosts in SIM first form an overlay tree using a scalable protocol. They then detect IP multicast islands and employ IP multicast whenever possible. We study the key issues in the design, including overlay tree construction, island management, and system resilience. Through simulations on Internet-like topologies, we show that SIM achieves lower end-to-end delay, lower link stress, and lower resource usage than traditional ALM protocols.
