DE (Discard Eligible)

In the frame relay LAPF frame, a 1-bit field indicating the eligibility of the

frame for discard under conditions of network congestion. Theoretically, the user equipment sets the DE

in consideration of the acceptability of the application to packet loss. Should the user equipment not set the DE, the network routers and switches may do so on a random basis or to police traffic that exceeds the CIR. SDLC, voice, and video traffic, for example, do not tolerate loss gracefully, and so typically are engineered to avoid DE status. File transfer and e-mail applications are not time-sensitive and, therefore, are highly insensitive to latency and loss.Therefore, the user may offer them to the network marked DE and pay a lower cost. See also congestion, frame relay, LAPF, latency, and SDLC.

• 1. Domain Name System. The naming convention that divides the Internet into logical domains identified in Internet Protocol version 4 (IPv4) as a 32-bit portion of the total address.The standard convention is user@organization.domain, where user is the name of the end user, organization is the name of the enterprise or other organization owning or sponsoring the address, and domain is the type of entity owning or sponsoring the address.The administration of the DNS is the responsibility of Internet Corporation for Assigned Names and Numbers (ICANN). See also domain, ICANN, Internet, and IPv4. 2.
• 1. In storage, irrelevant material, usually zero (0) bits, added to a data block in order to fill it to a minimum size, to force certain fields of control data or user data into certain positions or sizes, or to prevent the user data from duplicating a bit pattern that has a specific control meaning. See also block. 2.
