Abstract
With increase in the quantum of data in organisations, new strategies have to be developed to handle data in the cloud. Cloud computing is being used to store data virtually and access is being provided to users based on their requirement. The choice of the cloud also depends on the nature of data. With cloud storage, a large number of Disaster Recovery Sites (DRS) are being designed to handle database crashes. In this condition, the communication between the production database and DRS sites has to be handled efficiently. Optical connectivity is one promising solution to ensure reliable transmission. But again when data volumes are high, new models have to be developed, so that, data loss is minimal. In this research, a probabilistic routing model has been proposed using Weibull distribution. A routing topology based on multistage crossbar topology has also been introduced by utilizing cross points. A cross point is being activated based on the actual requirement. This model ensures optimal and reliable communication. The Reliability Effective Selective Switching strategy (RESS) proposed in this research reduces the average request burst by 22%, compared to the Reconfigurable Optical Add/Drop Multiplexer (ROADM) method currently available. The RESS technique proposed reduces the communication cost by 27%, compared to the conventional ROADM technique.
