To achieve such an objective demands a highly flexible and innovative core switch architecture. The operation and performance of such an architecture is the subject of this paper. The paper directly addresses the performance of the core OPS module and results obtained from simulation models show that the proposed asynchronous OPS architecture exhibits low latency and packet losses allied with relatively high throughput. </ABSTRACT></RECORD></RECORDS></XML>
