Detection Of Transmission Data Error In Distributed Computer System Through Uml

In a distributed computer system, the communication is done by using point-to-point or broadcasting technique among the processes running concurrently. Any process running in a distributed system can access the any resource or communicate with another process that can reside locally or on a remote site. There can be error occurred in data or message bit streams or it may be altered during the transmission from one machine to other machine over the network, Cyclic Redundancy Code (CRC) is a well-established method for ensuring the data integrity during data transmission. In the present paper, authors have proposed a UML model for detection of transmission data error in distributed computer system. The purpose to design this model is to minimize the data transmission error over the network. UMI, class, sequence and activity diagrams are presented for the computation of transmission error. The performance of this model is also reported in this paper through a case study.
