List of terms

data flow preservation

The process of maintaining uninterrupted data flow over a sequence of potentially disruptive events. Connection preservation is implied whenever data flow is preserved. Data flow preservation does not guarantee that data is never discarded (for example, due to either congestion or error conditions).

See connection preservation (page 34).

data link control (DLC)

An interface that provides logical link control connection services.

data link switching (DLSw)

A forwarding protocol for wide area network support of the NetBIOS protocol.

data manipulation engine (DME)

The data manipulation engine (DME) is the base service that provides capabilities for moving data frames to/from link interfaces and between function processors within a Nortel Multiservice Switch node. It is designed to provide protocol-based applications with the capability of performing operations on data frames. Such operations are packet header manipulation, packet retransmission, timing events, and queuing.

data network address (DNA)

A DNA is an identifier given to applications in many data networks. This address is used as the fundamental identifier for setting up a virtual circuit between data networks.

data packet network

Astandards-based data networking system for interconnecting diverse host, application, and end-user environments. The system gives organizations the ability to choose the best solutions for data networking. DPN-100 addresses the needs of organizations for reliable multi-protocol data services, such as frame relay, SNA, and X.25, at speeds up to T1/E1. It supports a wide range of physical interfaces including V.24, V.35, V.36, X.21, G.703, and token ring. The highest possible availability, 99.999%, is achieved through networking features, built-in redundancy, and a modular design.

data path object (DPO)

A data path object is a C++ object that processes frames at the interrupt level on a Nortel Multiservice Switch card. A frame processes by passing through a chain of DPOs; each DPO returns the ID of the next DPO in the chain. You can configure a DPO to be addressable module-wide.
