In order to meet the needs of the localized testing for NGBOSS specification and avoid the diversities testing standard caused by incompatibility between different integrators’ evaluation tools

this paper presents a method called SCP simulator which based on distributed processing.By analogizing message exchanges between the SCP nodes and BOSS

this method verified the functional and performance indexes as well.The method has already been proved to be feasible through practically verifying and seen a dramatic reduction of cost as well as increases in testing efficiency.
