: The paper addresses the idea of utilization of Erlang formulas in asynchronous ATM and IP networks. Based on the common properties of synchronous and asynchronous networks we have proposed the utilization of Erlang formulas not only for synchronous networks, but also for asynchronous networks. It is possible to describe traffic in asynchronous networks by calculation of following parameters –...

This document describes a method to improve the bandwidth utilization of network paths that carry multiple streams in parallel sharing a common path. The method combines standard protocols that provide compression, multiplexing, and tunneling over a network path for the purpose of reducing the bandwidth used when multiple streams are carried over that path.

This document contains recommendations of maximum tolerable delays to be added by methods which improve bandwidth utilization through compression, multiplexing, and tunneling over a network path. Recommendations are presented only for real-time network services for which such bandwidth optimization techniques are applicable (i.e., services with low payload size to header size ratio).

In recent years, BitTorrent has emerged as a very popular and scalable peer-to-peer file distribution mechanism. It has been successful at distributing large files quickly and efficiently without overwhelming the capacity of the origin server. Early measurement studies verified that BitTorrent achieves excellent upload utilization, but raised several questions concerning utilization in settings...

Internet has become an integrated carrier gradually, which has multi business such as data, voice, video, multimedia and so on. New multimedia applications require the network to guarantee quality of service. MPLS network has the capability of routing with some specific constraints for supporting desired QoS, out of which bandwidth is the most important constraint. The efficient routing algorit...

This paper proposes a novel call admission control scheme capable of providing a combination of call and packet level quality of service requirements in cellular packet networks. Specifically, we propose a distributed call admission control scheme called PFG, which maximizes the wireless channel utilization subject to a predetermined bound on the call dropping and packet loss probabilities for ...

The bandwidth adaptation is the technique that allows the flexibility in bandwidth allocation for a call. Using the bandwidth adaptation technique, the number of call admission in the system can be increased significantly. In this paper we propose a priority based bandwidth adaptation scheme that can release multi-level of bandwidth from the existing calls to accept call requests. The amount of...

Call admission control is a key element for providing quality of service (QoS) in mobile wireless networks. Traditional admission control schemes only address call-level QoS guarantee because of the underlying circuit-based network architecture. In contrast, emerging wireless technologies such as 3G and 4G tend to be packet-switched rather than circuit-switched because the packet-based architec...

In future wireless networks such as the Wireless ATM networks, it is important to guarantee quality-of-service (QOS) for mobile terminals. However, guaranteeing QOS while ensuring high bandwidth utilization is di cult because of the unpredictable nature of the terminals mobility pattern. In this paper, we propose a new scheme to improve the QOS of Wireless ATM networks by using predictive reser...

Logging while drilling (LWD) is a drilling technique which obtains and transmits the logging data during oil/gas drilling operations. Because of the limited available transmission bandwidth of mud channel, how to improve the bandwidth utilization becomes a critical problem in LWD research. In this paper, by discussing the information entropy of real logging data, we find that the original encod...
