On Design of Topological Structures of Interconnection Survivable Computer Communication Networks

Abstract

The rapid development in the field of information communication technology is changing the newlineway that we live, work, and play in various ways. One such essential change is the transition newlineof the industrial economy to the networked economy. The main basis of networked economy newlineis human knowledge, computers and connectivity. It s a type of economic environment newlineescalating from the digitization of fast-growing, multilayered, highly interactive, real-time newlineconnections among people, devices, and businesses. The communication network system newlineoperates behind the scenes for seamless communication, cohesive functioning, and effective newlineresource sharing. End users usually don t think about them unless something goes wrong. newlineHence communicating network structure is the major critical and vital infrastructures for newlineeffective and reliable communication system. newlineThe most significant technical and perpetual challenge for network designers in topological newlinedesign of critical and large scale communication networks is to attain higher level newlinesurvivability and dependability at lower cost. Dependability is concerned with the newlinetrustworthiness of the communication networks system It is generally defined using four newlineattributes namely reliability of the network, availability of the network, safety of the network newlineand security of the network . Survivability of a communication network system is the ability newlineof a system structure to continue operating in spite of the presence of abnormal events. newlineAbnormal events may be a failure or an intrusion or an attack, or it may be an accident. Both newlinethe design requirements viz. dependability and survivability attributes in the design of newlinecomplex communication network infrastructure topologies, are measurable attributes. newline The most common accepted measurable attribute in the design of network topological newlinestructures by network designers and researchers is the concept of fault-tolerance. This thesis newlineaddresses the major network research design issues and concepts which has direct impact on newlinethe performan
