Optical Communication System implies Elements, Devices and Systems. Optical Networks consists of three domains such as Networking, Switching and Routing. Survivability plays an important role in order to protect the network from failures. Hence survivability in optical network determines the interconnectivity between user and system configurations. Today’s Optical Network Environment (ONE) presents N X N and carries the demands in terms of THz. Thus two modes are described to plan and design of SFON; they are Physical Layer Mode (PLM) and Logical Layer Mode (LLM). PLM consists of cross connectivity of digital signals, bandwidth estimation, user survivability impact ratio, network path estimation and network capacity model. In LLM it describes the user node and flow survivability path, scaled the node position dependency and independency between different topologies to evaluate the throughput of the system Tier Configurations (TC). Further these modes present the Local and Global fairness (LGF) scenario regarding the packet transfer between Single Period Demand (SPD) to Multi Period Demands (MPD). The DCS Network, Restoration methods are processed by using five phases viz. Detection, propagation, Routing, Rerouting and Normal Path. Further these methods can be implemented by Self Healing Centralized Demand (SHCD) and Distributed Demand(DD) , Static versus Dynamic rerouting path and signal restoration level by using Network Restoration i.e. Digital Cross Connectivity.
