Baby , Eldho (2013) Rise Time Based Quality Analysis of Optical Networks. MTech thesis.
The optical network is becoming an important aspect for the present internet communication infrastructure due to good bandwidth provided by optical fiber. The throughputs provided by these networks are of the order of terabits per second, which is tremendously high. It also provides low error rates and low delays, and can also satisfy upcoming applications like supercomputer visualization, medical imaging, and distributed CPU interconnect. In optical networks, lightpath is defined as an all optical WDM channel which establishes a connection between source and destination node by network layer. Whenever the selected path doesn't satisfy the required criteria of either BER or Q-Factor or data rate, the connection will be blocked. Nowadays Wavelength division multiplexing (WDM) is used in optical networks in order to handle the increasing demand of network users. Nowadays, most of the network operators are very strict in terms of Quality of service parameters. The underlying routing systems determine the actual quality of transmission and the concept of Quality of service is based on this system parameters, can be defined as the overall service experience along with customer satisfaction of customer satisfaction. Lots of works has been done in finding Quality factor early using the effect of several parameters like bandwidth and delay, but this paper focuses mainly on finding quality of transmission using rise time and studies the effect of rise time on transmission data rate and other parameters. Here, we have taken a random network topology with 10 nodes and found out Q-factor for all possible paths and the shortest path for the given source and destination. The analytical model for Q-factor is linked with the rise time of various components in optical communication system and in turn system rise time.
