ioPLEX OVERVIEW The ioPLEX is an affordable, high-performance IP access gateway that offers support for more data types, higher aggregate throughput and better operational reliability than other circuit emulation devices on the market today. Featuring Assured DeliveryTM, in which diverse-path routing, packet reordering, intelligent reconstruction and other technologies are employed to guarantee data delivery, ioPLEX is ideal for applications in which data loss during network transit is simply unacceptable. Designed to move up to 2 Gbps of data across the network and generally introducing less than a millisecond of added latency into multiplexed streams, ioPLEX is also appropriate for very high rate and/or high-priority data circuits.

I/O MODULES AND NETWORK INTERFACES: ioPLEX I/O modules, once initialized and configured by the CPU, perform data processing tasks autonomously. During operation, traffic from access circuits are packetized, encapsulated using the pseudowire protocol, and transmitted with the applicable PSN header. Packetized streams received via the WAN are routed to the appropriate I/O module, any encapsulations are removed, and using the appropriate timing information the data is transmitted onto the access circuit.
