Load Management
for Distributed Object-Oriented Environments


Overview
In the past years object-oriented middleware like CORBA and DCOM became very popular. A significant problem of distributed object-oriented applications is load imbalance. As application objects are distributed over multiple hosts, the slowest host determines the overall performance of an application. Load management services try to compensate load imbalance by distributing workload.

Structure of LMC We implement a load management service for the CORBA middleware called LMC (Load Managed CORBA). LMC uses the Simple Network Management Protocol (SNMP) for load monitoring. The decision component of the load management service is integrated into the CORBA Implementation Repository. It evaluates the information provided by load monitoring and reaches a decision about load distribution by using an intelligent and flexible strategy. Finally, the load distribution, i.e. the functionality for object migration and replication, is integrated into the ORB and the POA in order to guarantee a high level of user transparency.
