VCAT differential delay minimization for delay sensitive multiservice networks

Abstract

This paper focuses on eliciting a simulated cost effective algorithm to better facilitate the transport of delay sensitive traffic types across future NextGeneration Multiservice core networks. It examines the Multiservice paradigm and isolates the VCAT standard addressing the current issue of largely incessant differential delays faced whilst creating virtual paths through the network. These large differential delays amount to large and costly high speed buffers that are required at the endpoints on the network in order for the system to function acceptably. By observation of the current trends, as the volume of traffic on these networks increases with time, the increasing buffer sizes will eventually lead to unacceptable network maintenance costs as well as large physical property/estate required to house the buffers in the network nodes themselves. The paper thus explores the problem in detail and poses a solution based on the simulation findings to minimize the incurred differential delays. This finding thus provides an option by which the cost and housing space of the required buffers may be minimized, thereby increasing the maintainability of the networks themselves.
