Dynamic Routing
Dynamic routing uses a routing protocol to exchange routing information
with neighboring routers on the network. It calculates routing tables based
on a given metric, such as least number of hops or shortest path. It can
respond to changes in the status or traffic on the network, re-routing
traffic as required.
Ethernet
A network communication system developed and standardized by DEC,
Intel, and Xerox, using baseband transmission, CSMA/CD access, logical
bus topology, and coaxial cable. The successor IEEE 802.3 standard
provides for integration into the OSI model and extends the physical layer
and media with repeaters and implementations that operate on fiber, thin
coax, and twisted-pair cable.
File Transfer Protocol (FTP)
A protocol commonly used to transfer files across the Internet.
Filter
When using G.lite ADSL, a low-pass filter is required to remove data
signals from any line connected directly to a telephone.
Firewall
A firewall is designed to prevent unauthorized access to or from a private
network.
G.dmt
A standard that defines full-rate ADSL, which utilizes Discrete Multi-Tone
(DMT) signaling to transmit data at up to 8 Mbps downstream and 640
Kbps upstream.
