In OSPF, an area that consists of all networks in area ID 0.0.0.0, their attached routers, and all area border routers.
An OSPF router with all operational interfaces within area 0.0.0.0.
On an M40 router, component of the Packet Forwarding Engine that distributes power, provides signal connectivity, manages shared memory on FPCs, and passes outgoing data cells to FPCs. See also flexible PIC concentrator (FPC).
Denotes a Routing Engine in a dual Routing Engine chassis that is not currently controlling the router’s operations.
An OSPF router on a broadcast segment that monitors the operation of the designated router and takes over its functions in the event of a failure.
The range of transmission frequencies a network can use, expressed as the difference between the highest and lowest frequencies of a transmission channel. In computer networks, greater bandwidth indicates faster data-transfer rate capacity.
Key network node in 3G systems that supervises the functioning and control of multiple base transceiver stations.
Composed of the base transceiver station (BTS) and base station controller (BSC).
Processes routing and quality-of-service (QoS) information for the BSS.
Mobile telephony equipment housed in cabinets and co-located with antennas. Also known as a radio base station.
Bell Communications Research. Research and development organization created after the divestiture of the Bell System. It is supported by the regional Bell holding companies (RBHCs), which own the regional Bell operating companies (RBOCs).
Algorithm used in distance-vector routing protocols to determine the best path to all routes in the network.
A test that can be run on an electrical point-to-point interface (T1, E1, T3, E3, etc.) to determine whether it is operating properly.
The use of fields in the header of an IP packet as match criteria in a firewall filter.
The single router in a multicast network responsible for distributing candidate rendezvous point information to all PIM-enabled routers.
Exterior Gateway Protocol used to exchange routing information among routers in different Autonomous Systems.
Operation of sending network traffic from one network node to all other network nodes.
Dedicated timing source that synchronizes all equipment in a particular building.
Collection of software that makes up a JUNOS software release.
