DWDM: Dense Wavelength Division Multiplexing
Dense wavelength division multiplexing (DWDM) is a fiber-optic transmission technique that employs light wavelengths to transmit data parallel-by-bit or serial-by-character.
DMVPN : Dynamic Mutilpoint Virtual Private Network
MDRR: Modified Deficit Round Robin
WRED: Weighted Random Early Detection
WCCP : Web Cache Communication Protocol ( Cisco )
it specifies interactions between one or more routers (or Layer 3 switches) and one or more web-caches. The purpose of the interaction is to establish and maintain the transparent redirection of selected types of traffic flowing through a group of routers. The selected traffic is redirected to a group of web-caches with the aim of optimizing resource usage and lowering response times.
DSCP : Differentiated Services Code Point ( rfc 2474 )
it is an integer encoded in the DS field of an IP packet header that enables different levels of service to be assigned to network traffic.
