Optical Burst Switching (OBS): The Future Switching Technology
نویسندگان
چکیده
Due to broadband internet access and shifting of paradigm from voice to data services, the internet traffic has doubled every year [1]. Increasing demand for multimedia live streaming and other bandwidth hungry services is on its great pace. The Cisco census in Figure 1 shows that these bandwidth hungry applications like IPTV, video chat, VOD, video conferencing, e-commerce, online banking etc are sharing 80% of total annual generated internet traffic that is still increasing with passage of time. The generated traffic in the access network is more or less concentrated in the backbone (core) network. As a result traffic load increases on the metro and core (backbone) transport networks. The next generation future networks should provide high transmission (bandwidth) and fast switching technologies in order to fulfill the requirements of increasing traffic demanding applications [2].

متن کاملManaging Contention Avoidance and Maximizing Throughput in Obs Network
Optical Burst Switching (OBS) is a promising technology for future optical networks. Due to its less complicated implementation using current optical and electrical components, OBS is seen as the first step towards the future Optical Packet Switching (OPS). In OBS, a key problem is to schedule bursts on wavelength channels whose bandwidth may become fragmented with the socalled void (or idle) i...
