Optical Burst Switching

Optical burst switching is a promising solution for all optical WDM networks It combines the benefits of optical packet switching and wavelength routing while taking into account the limitations of current all optical technology In OBS the user data is collected at the edge of the network, sorted based on destination address,and grouped into variable sized bursts Prior to transmitting a burst, a control packet is created and immediately send toward the destination in order t ....etc

SEMINAR ON OPTICAL BURST SWITCHING (OBS)

...
ABSTRACT
Optical Burst Switching is a promising hybrid approach between coarse grain optical circuit switching and fine grain optical packet switching. burst switching (OBS) is proposed as a way to streamline both protocol and hardware in building the future generation Optical Internet. Byleveraging the attractive properties of optical communications and at the same time, taking into account its limitations, OBS combines the best of optical circuit switching and packet/c ....etc

ABSTRACT
To meet the demanded bandwidth requirements of future optical communication networks, more dynamism,scalability and automatism will need to be provided, which will require, as well, new control plane designs to respond to network changes very rapidly. In this work, we propose the use of an ant colony optimization (ACO) algorithm to support the routing and wavelength assignment in wavelength continuity constraint optical burstswitched networks. The main advantage of the protocol is its distributed nature, which provides higher survivab ....etc

Optical switching enables routing of optical data signals without the need for conversion to electrical signals and, therefore, is independent of data rate and data protocol.Optical Burst Switching (OBS) is an attempt at a new synthesis of optical and electronic technologies that seeks to exploit the tremendous bandwidth of optical technology, while using electronics for management and control.

In an OBS network the incoming IP traffic is first assembled into bigger entities called bursts. Bursts, being substantially bigger than IP packets a ....etc
