In this paper, we address the problem of dynamic server selection among a set of objectservers, as the ones defined by CORBA and DCOM, providing the same service type. Theseservers are not necessarily replicas but may have different interfaces and belong to differentservice providers. As a solution, we propose a novel architecture that we call LoDACE. Thisarchitecture has been designed to allow...

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 had sharing service (LSS). Preliminary...
