A significant trend caused by cloud computing is to aggregate applications for sharing resources. Thus, it is necessary to provide fair resources and performance among applications, especially for the network, which is provided in the best-effort manner in current clouds. Although many studies have made efforts for provisioning fair bandwidth, they are not sufficient for network fairness. In fa...

This paper describes the experience of implementing CBQ's top-level link sharing code as described previously in [FJ95]. This implementation incorporates work from previous implementations of Class-Based Queueing from LBNL [Jac95] and UCL [WGC 95]. This implementation extends the work of previous implementations by incorporating both Top-Level link-sharing and Weighted Round Robin within priori...

The wide availability of mobile devices equipped with wireless communication capabilities together with the technical possibility to form adhoc networks paves the way for building highly dynamic communities of mobile users. An interesting application in such an environment is decentralized peer-to-peer file sharing and exchanging. Locating the required files in a highly dynamic network while mi...

The use of peer to peer file sharing networks such as Gnutella is proliferating on the Internet, but its use is bandwidth consuming due to the broadcast nature of some peer to peer protocols. This is undesirable for mobile devices due to their bandwidth and power constraints. This paper proposes an architecture that uses mobile agents to participate in the Gnutella network on behalf of mobile d...

To ensure service continuity in networks, local protection pre-configuring the backup paths is preferred to global protection. Under the practical hypothesis of single physical failures in the network, the backup paths which protect against different logical failure risks (node, link and shared risk link group (SRLG)) cannot be active at the same time. Thus, sharing bandwidth between such backu...

-For emerging Internet services and contents in the traffic-sharing environment of limited bandwidth capacity, an efficient method is required to manage the Internet-sharing problem and to improve quality of service (QoS) for highdemand bandwidth users. The results of our study show that dynamically delaying un-attended Internet usage activities, such as large file downloading, will drive more ...

As service providers move more applications to their IP/MPLS (Multiple Protocol Label Switching) networks, rapid restoration upon failure becomes more and more crucial. Recently MPLS fast reroute has attracted lots of attention as it was designed to meet the needs of real-time applications, such as voice over IP. MPLS fast reroute achieves rapid restoration by computing and signaling backup lab...

Over the years the Internet has shown extraordinary scalability and robustness in spite of the explosive growth in geographical reach, user population size, as well as network traffic volume. This scalability and robustness is, in no small part, supported by the Internet’s transport protocols, the Transmission Control Protocol (TCP) in particular. Nevertheless, with the rapid growth of multimed...

In this paper, we present a resource-aware and quality-fair video content sharing system. When a video sharing server has insufficient uplink bandwidth and needs to serve multiple video content sharing services via streaming or downloading to other client peers using TCP transport, each service shares the limited uplink bandwidth equitably, due to the fair sharing characteristics inherent in TC...
