Switch

A device (like a DMS-250 or a PBX) that responds to originator signals and dynamically connects the caller to the desired communication destination. ATM switch incorporates two layers: Physical layer and ATM layer. Generally, it should support ATM Forum Standard ABR, CBR, VBR and UBR services . ATM switch supports UNI or NNI or BICI or the combinations of these three interfaces.

For the congestion control, flow control and policing are needed. It also includes buffer management to ensure fair resource utilization between connections. Cell streams with CLP (cell loss priority) in ATM header equal to one may be optionally discarded before CLP equal to zero cell streams.

Connection Admission Control (CAC) uses profiles associate with an Network Management System (NMS) defined set of performance parameters and its static and dynamic knowledge of the ATM Layer switching fabric to minimize congestion on a per call basis for ATM Forum standard UBR, CBR, VBR and ABR sources. ATM Layer traffic and performance data are collected to monitor and to ensure end-to-end QoS guarantees are maintained.

Router

A device that connects LAN segments to other LANs or WANs. Routers operate at the network OSI layer 3 and transmit data that needs to cross network boundaries. Contrast with bridge. Router is a system that controls message distribution between multiple optional paths in a nework. Routers use routing protocols to gain information about the network, routing metrics and algorithms to select the "best route".

Bridge

A LAN internetworking device that filters and passes data between LANs based on Layer 2 (MAC layer) information. Bridges do not use any routing algorithms.

The following router/bridge integrate ATM with other LAN or WAN technologies. They are using Multiprotocol encapsulation over ATM and ATM LAN Emulation (LANE). With ATM Data Exchange Interface (DXI), these routers can support ATM UNI.

Video Codecs and Multiplexers

This equipment converts video and audio streams to digital information and thencompresses them into a flow of ATM cells. These cells are fed into an ATM network for transport to the destination where they decompressed and converted back into video and audio. Where multiple video streams must be compressed and converted, an optional multiplexer can aggregate them for input to a single port on an ATM switch. This technology is used in applications including distance learning, medical imaging, telemedicine, broadband video distribution, and remote arraignment.
