<p>PROBLEM TO BE SOLVED: To improve a throughout and to shorten a processing delay time by selecting a processor suitable for processing of a cell from received cells and transmitting information through a dedicated interface. SOLUTION: An ATM cell reception part 101 terminates an ATM cell and writes payload data and associated information to an appropriate frame buffer while checking a header. As soon as information is ready an extraction/judgment/insertion/mediation part 104 activates respective processing engines 200 as needed and respective processing results are reflected on a frame buffer 103. In the processing engine 200, an undefined processing and an exception processing are turned over to a CPU processing, abandoned or detected as an alarm or a fault while cooperating with a mediation control part/CPUIO part/register part 106. A frame for which the proceedings are ended is decomposed into the ATM cells, an ATM layer processing is executed and they are transmitted by an ATM cell transmission part 102.</p> |
