Resources used for recovery are not pre-reserved but chosen from available when the failure occurs. More efficient than predesigned protection on capacity but may require longer recovery time and overhead. These dedicated resource keeps idle when no failure happens.
The use of capacity is thus not efficient, but recovery speed can be guaranteed. Require more complicated algorithm on pre-plan stage. With the continuous advancement in technology data communication at higher data rates have become the need for the present and future technology. The data can be highly sensitive and loss of such data can hamper the communication which can cause huge loss to data, time and revenue. Thus survivability plays a very crucial role in optical networks. It is the ability of the optical network to overcome failure by pre-reservation of resources or by finding available resources after link failure has occurred Since optical network survivability is narrow area were till there lot of research w.
In this area there are very few expertise are available. We will explain the concept of survivability with photonics networks with simple examples so that everyone try to understand and implements the same.
Optical Networks - Architecture and Survivability, is a state-of-the-art work on survivable and cost-effective design of control and management for networks with . Initial work on survivability in WDM optical networks has. focused mostly .. For example, if the BSHR/2 architecture is used in. WDM systems.
It is having lot of scope in upcoming broadway Technologies. Detailed Information about Chapters While the work focused on optical networks, the methods developed are not network specific and can be applied to many types of networks employing a variety of transmission and switching technologies They are: 1. Develop models of optical-broadband access networks and trunk networks based on projected traffic growth.
Evaluate the impact of emerging technologies on network architecture design. Develop routing algorithms for optical layered networks.
Investigate the potential for packet switching procedures and burst switching in optical networks, i. Logical Layer Topology. The Performance and Evaluation of Optical networks take into consideration the factors like trade-off between routing traffic at the optical layer, creating dedicated light paths in order to maximize the traffic carried and the availability of spare capacity.
