Topology-Centric Look-Up Service
نویسندگان
چکیده
Topological considerations are of paramount importance in the design of a P2P lookup service. We present TOPLUS, a lookup service for structured peer-to-peer networks that is based on the hierarchical grouping of peers according to network IP prefixes. TOPLUS is fully distributed and symmetric, in the sense that all nodes have the same role. Packets are routed to their destination along a path that mimics the routerlevel shortest-path, thereby providing a small “stretch”. Experimental evaluation confirms that a lookup in TOPLUS takes time comparable to that of IP routing.

A Peer-Tree Based Location Lookup Service in Mobile Wireless Networks
We present a location look-up service for aiding location-based routing in wireless networks with mobile hosts. This location look up service is constructed based on a peer-tree indexing structure which represents the friendship relations among mobile hosts. The friendship is derived from the relations of sharing various-length common suffixes of host identifiers. A friendship relation determin...
متن کاملA QoS centric layered transmission topology for multimedia data in wireless cellular networks
Here in this paper, we propose a routing topology for audio visual data transmission over Cellular networks, which is Quality of Service Centric. A novel scheduling mechanism introduced to distinguish the arbitrary loss of the data packet and transmission delay. The aim of the proposal is to achieve a layered approach in the tasks involved in audio and visual data routing. The expected layered ...
متن کاملTRANS-Net: an Efficient Peer-to-Peer Overlay Network Based on a Full Transposition Graph
In this paper we propose a new practical P2P system based on a full transposition network topology named TRANS-Net. Full transposition networks achieve higher fault-tolerance and lower congestion among the class of transposition networks. TRANS-Net provides an efficient lookup service i.e. k hops with high probability where k satisfies 2 (log ) (log ) n m k m , where m denotes the number of sys...
متن کاملModeling Service Applications for Optimal Parallel Embedding
Leveraging the traditional virtual network concept, some recent research works have proposed the Virtual Data Center (VDC) as an abstraction to capture both bandwidth and compute/storage resource requirements for an application. However a virtual node in a VDC is limited to a virtual machine (VM), which can only be embedded onto a single physical machine. This condition limits the applicability...
متن کاملQoE Testbed Infrastructure and Services: Enriching the End User's Experience
Quality of Experience (QoE) is the subjective judgment of the satisfaction an end user perceives from an application running over a given network topology and configuration. The information provided by end users regarding their QoE preferences, experience and feedback is invaluable in providing a service that meets with their mobile activity needs within various access networks. The PERIMETER p...
