Title
Dynamic management of CORBA trader federation
Abstract
In Wide Area Networks, tools for discovering objects that provide a given service, and for choosing one out of many are essential. The CORBA trading service is one of these tools. A trader federation extends the limit of a discovery, thanks to the cooperation of several trading servers. However, in a federation, cooperation links are manually and statically established. In this article, we propose an Extended Trading Service, which manages a trader federation dynamically. With Extended Trading Service, optimized links between traders are automatically set up thanks to the use of a minimum-weight spanning tree. Cycles in discovery propagation are eliminated. Links evolve dynamically in order to adapt to the modification of the underlying topology and the failure of an intermediate trader or link. The Extended Trading Service is able to organize discovered objects from the nearest to the furthest according to a distance function chosen for the federation. Such management is provided by specialized trading servers conforming to OMG Trading Service Specification.
