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.

Lack of incentives makes most P2P users unwilling to cooperate and lead to free-riding behavior. One way to encourage cooperation is through service differentiation based on each peer’s contributions. This paper presents FuzRep, a reputation system for P2P networks. FuzRep uses fuzzy logic method which uses requester’s reputation and provider’s inbound bandwidth as input information to create incentives for sharing and to avoid overloading problems for primary file providers. Reputation sharing in FuzRep is implemented by interest-based selective polling, which can significantly decrease overheads for reputation communication.
