OBS FOR GENNEXT OPTICAL NETWORKS

Abstract-The current Internet is suffering from its own success. As the number of users on the Internet and the variety of applications transported are growing steadily at high rate, the available bandwidth as well as the besteffort paradigm is facing limits. Ubiquitous and frequent congestion situations restrict the use of new timecritical applications like IP telephony, video conferencing or online games. Thus, there is an increasing demand for both bandwidth and some sort of scalable quality of service (QoS) support too. In this paper we analyze the performance of various algorithms applied at the edge nodes of an OBS network, in terms of resulting loss at the core OBS node I
