Differentiated Services Code Point (DSCP)

The first six bits of the DS field. The DSCP uses packet marking to guarantee a fixed percentage of total bandwidth to each of several applications (guarantees Quality of Service).

digital subscriber line (DSL)

In Integrated Services Digital Networks (ISDN), equipment that provides full-duplex service on a single twisted metallic pair at a rate sufficient to support ISDN basic access and additional framing, timing recovery, and operational functions.

digital subscriber line access multiplexer (DSLAM)

A network device, at a telephone company central office, that receives signals from multiple customer digital subscriber line (DSL) connections and uses multiplexing techniques to place the signals on a high-speed backbone line.

Dual port controller (DPC)

A Field Programmable Gate Array (FPGA) device on the R module.

dispersion

The broadening of input pulses as they travel the length of an optical fiber. The following types of dispersion exist:

•modal dispersion-caused by the many optical path lengths in a multimode fiber

•chromatic dispersion-caused by the differential delay at various wavelengths in an optical fiber

•waveguide dispersion-caused by light traveling through both the core and cladding materials in single-mode fibers

Distance Vector Multicast Routing Protocol (DVMRP)

A dense mode routing protocol that floods multicast data to all internetwork routers.
