Background process that performs operations on behalf of the system software and hardware. Daemons normally start when the system software is booted , and they run as long as the software is running. In the JUNOS software, daemons are also referred to as processes.
Method of reducing the number of update messages sent between BGP peers, thereby reducing the load on these peers without adversely affecting the route convergence time for stable routes.
data circuit-terminating equipment
data-link connection identifier
data service unit
Data Terminal Equipment
The JUNOS software interface process (daemon).
Data circuit-terminating equipment. RS-232-C device, typically used for a modem or printer, or a network access and packet switching node.
Router address that is used as the source address on unnumbered interfaces.
denial of service
In OSPF, a router selected by other routers that is responsible for sending link-state advertisements that describe the network, which reduces the amount of network traffic and the size of the routers' topological databases.
destination prefix length
Number of bits of the network address used for host portion of a CIDR IP address.
Dynamic Host Configuration Protocol. Allocates IP addresses dynamically so that they can be reused when they are no longer needed.
Dual-inline memory module. 168-pin memory module that supports 64-bit data transfer.

Data-link connection identifier. Identifier for a Frame Relay virtual connection (also called a logical interface ).
Denial of service. System security breach in which network services become unavailable to users.
Dynamic random-access memory. Storage source on the router that can be accessed quickly by a process.
Data service unit. A device used to connect a DTE to a digital phone line. Converts digital data from a router to voltages and encoding required by the phone line.

Data Terminal Equipment. RS-232-C interface that a computer uses to exchange information with a serial device.
Distance Vector Multicast Routing Protocol. Distributed multicast routing protocol that dynamically generates IP multicast delivery trees using a technique called reverse path multicasting (RPM) to forward multicast traffic to downstream interfaces.
