| Abstract: | DCOM extends the Component Object Model(COM)to support communication among objects on different computers on a LAN,a WAN,or even the Internet.This paper discusses how to implement the extensibility of an appli-cation server based on the DCOM architecture using the techniques such as parallel deployment and isolating critical components.The implementation of load balancing among the servers through the referral component and its dynamic load-balancing algorithm is also discussed. |

| Keywords: | COM DCOM parallel deployment isolating critical components load balance |
