QUALITY OF SERVICE (QoS) IN CAMPUS NETWORK: COMPREHENSIVE SURVEY

Abstract

The Internet has provided end-to-end connectivity for users, allowing Quality of Service (QoS) management of network resources for new applications, such as data center, cloud computing, and network virtualization. Although manys solutions have proposed to solve the QoS drawbacks of the recent networking, numbers of them are failed or were not implemented. This paper is to address the comparison between available solutions of QoS in campus network which is related targeted goals of QoS future development in the campus network. The analysis will help future research to decide the best technique to be used in any QoS solution domain.

owadays, the explosive growth of real-time applications that require stringent Quality of Service (QoS) guarantees, brings the network programmers to design network protocols that deliver certain performance guarantees. While, with the huge and rapid advance of a computer network, the structure of the campus network is the inescapable choice of the improvement of the information network. The campus network framework is quite large and complicated system. It is not only for modern teaching, integrated information management and office automation series of applications to provide a basic operating platform, but also to provide a variety of application services, so that information can be timely and accurate delivery. The campus network construction in the application of network technology is the important branch of LAN technology to build and management [1]. The capacity of the current Internet with rapid growth is becoming insufficient to carry the large volumes of traffic patterns delivered by the new services and modalities, where new types of networking services are appeared and generated for a huge number of end users. Specifically, the currently utilized infrastructure system of the network has been preserved almost in the same structure for decades, while technology continues to evolve. Resource management is of paramount importance in network scenarios and it is a long-standing and still open issue. Where the existing networks have built with multiple stages of static Ethernet switches organized in a tree structure are not sufficient for the dynamic computing and storage needs of today’s carrier environments and future developments. The improvement of the network speedup, scalability, and robustness with the effective creation and delivery of versatile digital services that provide stringent Quality of Service (QoS) guarantees is a key demand. However, all of these services and applications require different treatments for their own ows to make the delivery successful over a network (e.g. some applications such as video conferencing require a certain bandwidth for its flow, other applications are sensitive to the delay over a network, and more other specific requirements. Thus, defining these needs a well-understanding Quality of Service (QoS) mechanism(s) in a network is a unique term
