Introduction to Seminar Topic on Optical Network Architecture:

The major concern in present days in the networking is demanding for more bandwidth. Optical networks and Dense Wavelength Division Multiplexing has occupied a crucial role in the networking technology. The usage of SONET now a days is well suited for normal traffic but not for high-speed traffic. To upgrade the existing system to handle high speed traffic is very expensive implementation. Hence implementation of optical network has evolved.

A light path is the path between two nodes. The two types of network topologies include physical and virtual topology. In the physical topology the nodes are cross-connected by pairs. When we consider a virtual topology in a network it is a collection of light paths. Virtual topology is a logical topology where all the directions of arrows show the way of direction of light paths.

An optical layer also known as layer1 in some cases, this optical layer is the layer between the physical and data link layer. The sub layers of optical layer includes Optical Channel layer: which corresponds to light paths, Optical Multiplex Section: which deals with links and Optical Amplifier Section: It deals with line segments between optical amplifiers.

In this paper we discussed about optical networks. And also virtual topology and optical layer is also in brief. In this paper discussed about network control and management of network. 

And a study of research is done for improving speed of optical network.  In the implementation of optical systems cost plays a vital role, a lot of standards need to be done for implementation of optical networks at reasonable cost. Therefore we have concluded that the implementation of optical systems is reasonable when compared to that previous systems.
