A proposal to improve network throughput using a QoS building blocks approach at Central University of Venezuela

Abstract

Central University of Venezuela is the main university of Venezuela and has approximately 60,000 students and 16,000 staff members. The backbone network connects 11 colleges and many non-academic dependencies; some of them are located outside the main campus and even in other regions of the country. The Internet access is centralized and supported by private links at an aggregated data rate of 14.336 Mbps. Users of the institution network can access most of the Internet services with few or non restrictions. In the last few years, there has been an increasing demand on the use of the Internet services provided by the institution. The consequences of the above are degradation of the Internet access services provided by the institution to users, which claim for better response times and throughput. In this paper, we propose a solution to this problem based on the use of congestion control mechanisms and Internet service approaches proposed by the IETF. So, we start the paper given a brief introduction of such mechanisms and service models; then we detail the problem of the campus network and finally we describe the proposed solution. We conclude that the problem of network congestion may be reduced using existing congestion control mechanisms, which can complement a solution based on network over-provision.
