In distributed appplication system, Totally Ordered Group Communication Service(TO-GCS) is very important, and it is a powerful infrastructure for building distributed fault-tolerant application such as distributed shared memory, Computer Supported Cooperative Work and distributed monitoring. Much work has been dedicated to Totally ordered multicast protocol. One of them, Adaptive Totally Ordered Multicast Communication(ATOP), is able to dynamically alter the message delivery order in response to changes in the transmission rates of group members. Based on this, a protocol ATOP/MBS is proposed and discussed. In this paper, we improve the ATOP/MBS and propose a protocol ATOP/improved MBS, which use no dummy message and can adapt well in case of transmission frequency changing in comparatively short period. According to the simulation results, TO-GCS with ATOP/improved MBS can be carried out at low delivery latency and fluctuations of delivery latency.
