Understanding the characteristics of Internet application structure and traffic is critical for traffic modeling and network optimization. In this paper, the behavioral structures of different Internet applications are constructed based on a large sample of flow data collected from operational network of ISP. For each application type, i.e. Web, P2P Stream, P2P Download, Video Stream, Instant Messaging...
Many Internet Service Providers, as part of a declared policy to control the impact of the growth of Internet traffic on their infrastructures, have started billing their users per volume transferred. Such a policy raises a number of issues which we present in this paper. For the most part, users are confronted with a bill which they cannot easily reconcile with their day to day use of the Internet...
P2P application has accounted a large proportion of the total Internet traffic. However, existing P2P topology formation protocols always assume a homogeneous environment or neglect the underlying Internet topology. These methods will increase inter-domain traffic so that ISPs always restrict the P2P traffic and current neighbor selection procedure always randomly chooses a peer as its neighbor probably...
BitTorrent (BT) has carried out a significant and continuously increasing portion of Internet traffic. While several designs have been recently proposed and implemented to improve the resource utilization by bridging the application layer (overlay) and the network layer (underlay), these designs are largely dependent on Internet infrastructures, such as ISPs and CDNs. In addition, they also demand...
Peer-to-Peer (P2P) systems have gained much popularity over the past few years. P2P networks contribute a significant portion of the Internet traffic and cause increasing costs incurred by Internet service providers (ISP). Present P2P systems are generally selecting peers in random manner, regardless of the network cost, which generates much redundant traffic over the core network and congest the...
BitTorrent, one of the most popular peer-to-peer file sharing applications, accounts for a large proportion of the total Internet traffic. While its appearance benefits the content distributors and users, the traffic injected into the network backbone has become a great challenge for the ISPs. In this paper, we study traffic shaping in BitTorrent-like applications to improve traffic locality and enable...
Due to the fact that P2P applications have dominantly accounted for the entire Internet traffic, how to efficiently manage P2P traffic has become increasingly important. It has been recently proposed that the underlying network information can be shared between ISPs and P2P service providers in order to achieve efficient resource utilization, with the locality-based peer selection being a specific...
In today's extensive worldwide Internet traffic, some 60% of network congestion is caused by Peer to Peer sessions. Consequently ISPs are facing many challenges like: paying for the added traffic requirement, poor customer satisfaction due to degraded broadband experience, purchasing costly backbone links and upstream bandwidth and having difficulty to effectively control P2P traffic with conventional...
Bandwidth provisioning is an important issue for Internet service providers (ISPs) and ensuring quality of service (QoS) is a major concern. QoS is closely related to the available bandwidth which itself is subject to financial constraints. Unfortunately, up to now there have been no adequate tools available in the market so that ISPs can do accurate bandwidth provisioning. In this paper, we describe...
