Currently, P2P application accounts for a majority of the network traffic. It is significant to study P2P recognition for network monitoring and management, as well as the improvement of service quality. There are many ways to identify P2P traffic, but it is difficult to identify effectively with only one method. To obtain the optimal classification, different methods should be used comprehensively...
Flooding search is a basic searching scheme for unstructured peer-to-peer networks. This technique produces exponentially redundant messages in each hop. Subsequent growths of redundant messages will limit system scalability and will cause unnecessary traffic in network areas. To improve this searching scheme and reduce redundant messages, this paper proposed a novel algorithm (SmoothFlood) which...
IP Television (IPTV) is a new service that is growing up very quick in recent years. Its implementation is performed as a Triple-Play service, being the integration of voice, high-speed data and television. Moreover, the network traffic has been increased due to the use of VoIP, video or P2P. It is also creating congestion problems to the network provider and has high impact on the quality of IPTV...
The continuous growth in both commercial and public network traffic with various quality-of-service (QoS) requirements is calling for better service than the Internet's best effort mechanism. One of the challenging issues is to predict the overall behavior of aggregate network traffic. While network traffic characterization has been studied extensively due to its importance in network scheduling and...
The Gnutella protocol requires peers to broadcast messages to their neighbors when they search files. The message passing generates a lot of traffic in the network, which degrades the quality of service. We propose the new method to optimize the speed of search and to improve the quality of service in a Gnutella based peer-to-peer environment with using semantic routing and priority of nodes. Once...
Over recent years there has been a large increase in the use of P2P (peer- to-peer) applications around the world. These applications have become very popular today and there are a lot of new users every day. Increasing of P2P users has a very great impact on increasing P2P traffic in communications networks. In this paper we pay attention to measuring of P2P traffic, by analyzing and simulating these...
The concept of SATO (Service-aware Adaptive Transport overlays) is proposed within a European project (Ambient Networks). It introduces a virtual network, named overlay network, to fit the particular requirements of the Ambient Networks' services, and to achieve service adaptation and service customization. In its first phase, the QoS consideration design relied only on the underlying physical network,...
