The Design of a Trader-based CORBA Load Sharing Service

摘要

In the context of CORBA, standard services for naming transaction processing and alike have been defined. However, no standard support is provided to handle load imbalances that may occur in distributed object applications where several object servers are used to provide the same service type. To address this shortcoming, we have designed a CORBA-compliant load sharing service (LSS). Preliminary experiments with LSS show that LSS allows for the uniform load distribution among servers. Furthermore, we report that load sharing via LSS performs better than the approaches based on the random and the round robin server selection methods, in terms of the average response time for client requests.
