Research on parallel technology of web services composition based on workflow

To improve the efficiency of web services composition based on workflow and satisfy the user's requirements, the parallel scheme for composing web services based on workflow is put forward, and algorithm is presented.The services in flow are divided into different service discovery module according to the number of service discovery module to discover services in parallel.Thus, the executing efficiency is improved.And it is illustrated and proved that the scheme is efficient.Finally, its advantages are concluded.
