Glossary
Simple Network Management Protocol. A widely implemented Internet network
SNMP —
management protocol that allows status monitoring, getting/setting of parameters for configuration
and control of network devices, such as routers and bridges.
Split B Channels — Each 64 Kbps ISDN B-channel can be used individually for a separate data
connection.
Spoofing is a technique used to remove poll and update service frames from WAN
Spoofing —
links while ensuring that the network continues to operate normally. Spoofing is employed to
minimize dial-up line connection time.
An extension of the Internet 32-bit addressing scheme that allows the
Subnet Address —
separation of physical or logical networks within the single network number assigned to an
organization. TCP/IP entities outside this organization have no knowledge of the internal
"subnetting."
Subnet Mask — A 32-bit internet protocol address mask used to identify a particular
subnetwork.
TCP/IP — Transmission Control Protocol/Internet Protocol. Refers to a set of internetworking
protocols developed by the U.S. Department of Defense that define a two level layered approach
for interoperability. TCP provides a connection-oriented Transport layer ensuring end-to-end
reliability in data transmission. IP provides for Network layer connectivity using connectionless
datagrams.
The "cloud" of switched virtual connections over a Wide Area Network (WAN).
Telco Cloud —
Internet standard protocol for remote terminal emulation that allows a user to
TELNET —
remotely log in to another device and appear as if directly connected.
TFTP — Trivial File Transfer Protocol. A simplified version of the File Transfer Protocol (FTP)
allowing for file transfer between computers over a network.
Bridging technique used in Ethernet networks that allows transfer of
Transparent Bridging —
frames across intermediate nodes using tables associating end nodes with bridging addresses.
Bridges are unknown to the end nodes.
User Datagram Protocol. A connectionless protocol used to pass packets across an
UDP —
internet network, requiring no handshaking between source and destination.
