چکیده

This paper introduces a scheme for online dynamic bandwidth allocation for variable bit rate (VBR) traffic over ATM networks. The presented method determines the optimum bandwidth renegotiation time and bandwidth amount to allocate to VBR traffic source by minimizing predefined cost functions. Traffic rate predictor designed by wavelets is provided as feedback to the system. The results show that the introduced scheme minimizes both under-utilization of the available capacity and queuing delays. The proposed method can also be deployed in Weighted Fair Queuing disciplines to dynamically update a weight coefficient assigned to an application.

Optimal Bandwidth Allocation in Communication Networks

Broadband-ISDN (BISDN) will be implemented using Asynchronous Transfer Mode (ATM). This is prompted by the need to handle a variety of types of services, with diverse demands on the network in terms of the bit rate required and their holding times. Continuous as well as variable bit rates will be serviced. Services with holding times in the range of milliseconds to hours will be admitted to the...

A Scalable Feedback-Based UPC-Parameters Renegotiation Scheme

In QoS-enabled network, for example ATM, connections which exhibit rapidly changing traffic characteristics, renegotiating the bandwidth requirements becomes inevitable. The sender initiates renegotiation whenever bandwidth requirements change. If the newly requested bandwidth is not granted, the sender keeps on invoking the follow-up renegotiations with some frequency. Polling the network too ...

Dynamic Bandwidth Allocation for ATMSwitches

We explore a dynamic approach to the problems of call admission and resource allocation for communication networks with connections that are differentiated by their quality of service requirements. In a dynamic approach, the amount of spare resources is estimated on-line based on feedbacks from the network's quality of service monitoring mechanism. The schemes we propose remove the dependence o...

Bandwidth Allocation for Virtual Paths in ATM Networks with Dynamic Routing

The Virtual Path (VP) concept in ATM networks simplifies network structure, traffic control and resource management. For VP formulation, a VP can carry traffic of the same type (the separate scheme) or of different types (the unified scheme). For VP adjustment, a certain amount of bandwidth can be dynamically assigned (reserved) to VPs, where the amount (the bandwidth incremental/decremental si...
