dense wavelength division multiplexing (DWDM)

A technology that uses many optical signals (16 or more) with different wavelengths to simultaneously transmit in the same direction across one fiber, and then separates by wavelength at the distant end.

demultiplexing

The wavelength separation in a wavelength- division multiplexing system. The opposite of multiplexing.

designated router (DR)

A single router elected as the designated router for the network. In a broadcast or nonbroadcast multiple access (NBMA) network running the Open Shortest Path First (OSPF) protocol, a DR ensures all network routers synchronize with each other and advertises the network to the rest of the autonomous system (AS). In a multicast network running Protocol Independent Multicast (PIM), the DR acts as a representative router for directly connected hosts. The DR sends control messages to the rendezvous point (RP) router, sends register messages to the RP on behalf of directly connected sources, and maintains RP router status information for the group.

Device Manager (DM)

A graphical user interface (GUI) used to configure and manage the Nortel Ethernet Routing Switch 8600.

DiffServ (DS) boundary or access point

The edge of a DS domain in which classifiers and traffic conditioners are deployed.

DS field

Formerly called the IPv4 Type of Service (TOS) octet or the IPv6 Traffic Class octet. The DS field provides the Differentiated Services Code Point (DSCP) that is used for packet forwarding. These fields are part of the standard IPv4 header.
