ATM (Asynchronous Transfer Mode) cell-switching technology is an efficient, scalable solution that integrates voice, video and data transmission. It offers a connection-oriented solution for high-speed networks. ATM relies on cell-switching technology. ATM cells have a fixed length of 53 bytes which allows for very fast switching. ATM creates pathways between end nodes called virtual circuits which are identified by the VPI /VCI values. ATM Signaling is the process by which ATM users and the network exchange the control of information, request the use of network resources, or negotiate for the use of circuit parameters. The VPI/VCI pair and requested bandwidth are allocated as a result of a successful signalling exchange. RADCOM supports protocol analysis at all seven layers and monitoring and anlaysis at the level of the physical interface. In addition, AAL2 and AAL5 reassembly is performed in real time by hardware. Furthermore, RADCOM generate ATM Signaling messages for cases when the function of ATM switch has to be tested. RADCOM provides extensive support for ATM at the cell level, frame level and ATM signaling and routing protocols, thus enabling support of today's most sophisticated cellular networks. |
