Router Information
Protocol (RIP) RIP is based on distance vector algorithms that measure the shortest path between two
points on a network, based on the addresses of the originating and destination devices. The
shortest path is determined by the number of hops between those points. Each router
maintains a routing table, or routing database, of known addresses and routes; each router
periodically broadcasts the contents of its table to neighboring routers in order that the
entire network can maintain a synchronized database.
Router Information
Protocol Version 1
(RIPv1) Original version of RIP. This is a classful routing protocol, it does not have the ability to
transmit the subnet mask within its updates. RIP v1 imposes the subnet mask on the
inbound interface and this is normally defined by the engineer. Learned routes are entered
into the routing table with their natural mask. As a result there can be a great waste of
internet host addresses.
Router Information
Protocol Version 2
(RIPv2) Second version of RIP, additional to Version 1, enables the use of a simple authentication
mechanism to secure table updates. More importantly, RIP 2 supports subnet masks, a
critical feature that is not available in RIP (v1).
SAP Service Access Point.
Session Initiation
Protocol (SIP) SIP is the emerging standard for setting up telephone call, multimedia conferencing, instant
messaging and other types of real-time communication on the internet.
signal A generated electrical impulse that is a change in voltage to trigger an event.
Simple Network
Management Protocol
(SNMP) SNMP is the most common method by which network managements applications can
query a management agent using a supported MIB (Management Information Base).
SNMP operates at the OSI application layer.
spanning tree Spanning Tree Protocol is a link management protocol that provides path redundancy while
preventing undesirable loops in the network. For an Ethernet network to function properly,
only one active path can exist between two stations.
SRV SRV is an resource record that specifies the locations of servers.
subnet mask 32-bit quantity indicating which bits in an IP address identify the physical network
T1 Trunk Level 1. A digital transmission link with a total signaling speed of 1.544 Mbps. T-1
is a standard for the digital transmission in North America.
telnet An Internet standard protocol that enables a computer to function as a terminal working
from a remote computer
TDM Time Division Multiplex. A technique for transmitting a number of separate data, voice
and/or video signals simultaneously over one communications medium by quickly
interleaving a piece of each signal one after another.
Terminal Endpoint
Identifier (TEI) Up to eight devices can be connected to one ISDN BRI (or PRI) line. The TEI defines, for
a given message, which of the eight devices is communicating with the Central Office
switch. In general, more than one of the eight may be communicating.
TFTP Trivial File Transfer Protocol.
