QUALITY OF SERVICE (QOS) IN CAMPUS NETWORK: COMPREHENSIVE SURVEY
Currently many aspects of the classical architecture of the Internet are extensively well-known, which has led to major obstacles in internet services. At present, there exist many reasons to extend the Internet including providing 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. Defining those parameters and causes which affect on internet services especially the QoS and developing significant ant techniques to solve them is continued to be a major challenge. Although developers, researchers, and scholars from different countries abroad have introduced and proposed numerous solutions to solve the QoS drawbacks of the recent networking, numbers of them are failed or were not implemented. Furthermore, many recent types of research have addressed the QoS in campus network and introduce new concepts toward QoS improvements such as the Software Defined Networking (SDN) in modern-generation architecture, the deployment of control plane software components (e.g., OpenFlow controller), and more. A critical understanding of the Quality of Service (QoS) in campus network obstacles is necessary to address the multiple challenges and realizing the QoS future development. To address these challenges and available solutions this paper review some existing techniques of QoS in campus network which is related targeted goals of QoS future development in the campus network.
