Abstract
Based on a clear separation between switching hardware and control
software, the concept of open signaling creates an open programmable
networking environment, in which network entities can be realized as high
level software objects with well-defined interfaces. This underlying
architecture facilitates the creation of multiple mechanisms of network
control, supporting applications for connection management. The feasibility
of a connection management framework however depends mainly on the
performance of CORBA because of binding overheads associated with remote
invocations. It has been proposed that an implementation with reasonable
performance may require certain criteria to be integrated into the design,
including caching of network states, aggregation of access to the switch
server object, and parallel processing of a single call request. This paper
considers the effectiveness of these design criteria and the associated
performance issues of a connection management system for ATM networks.
Keywords: open signaling, connection management, ATM networks, CORBA, open
programmable network.
