Signal performance optimization in the local area network trafic management in the DRC : Models for transmission networks (Published)

The high availability of computer networks is a prerequisite in large companies and service providers. Thus, computer network administrators are called upon to face the various growing challenges related to unscheduled downtime of services; lack of expertise; lack of tools; the complexity of technologies; market consolidation and competition to provide better quality services. It should be remembered that the organization of the networks of telecommunication aims at giving control of the phenomena which occur there, during the treatment of the communications, and more generally of the services which they offer. These phenomena are governed by the randomness of the appearance of the requests, and are studied independently of the choices of technology implemented. They are amenable to the formalism of the calculation of probabilities, and give birth to the notion of traffic, which will play a central role in their apprehension, given that they condition for a large part the effective structure of modern networks. This research specifically examines the problems of optimization of signal performance in traffic management of local area networks of companies in the Democratic Republic of Congo, by presenting the different elements of network traffic theory and quality. Thus demonstrating their impact on the architectures of networks and computer systems, and at the same time introducing the major problems faced by IT network administrators on a daily basis; The main objective of this research is to evaluate the development performance of computer and telecommunications networks according to their applications in the areas of network design, equipment dimensioning, and characterization and quality measurement. Service, and network planning techniques.

A General Guide for Communication System Engineers to Improve QoS (Published)

The Quality of Service (QoS) is one of most important issues in providing an acceptable level of service. Communication engineers need a guide for action to improve QoS parameters such as data rate, bit error rate, latency, and jitter. Improving QoS includes a set of steps that should be performed by an engineer; these steps are belonging to two categories, system and network steps. In this paper we developed a flow chart of a general guide to improve QoS in a digital communication system, based on our knowledge of the modern communication system and impairments that lead to system degradation. We outline the options and advices to approach the subject of QoS in digital transmission.

QOS Reliability and Improvement for Congestion Probability Routing in ATM Networks (Published)

The other primitives for switch management and control are borrowed heavily from the specified protocol. They include priority for switch configuration port and switch management VP management and permanent measurement. The protocol was implemented and integrated with the OPNET platform. Without going into specifies of the protocol we describe its design principles and show how it has affected in the protocol. Traditional connection switches include an embedded processor that implements both the switch control and network signaling. The objective of CAC is to keep the network load moderate to achieve a performance objective associated with QOS. Cell loss ratio a key QOS parameter in ATM networks is essential for proper network resources dimensioning, congestion control , bandwidth allocation and routing.
