Router Information Protocol (RIP)

Router Information	RIP is based on distance vector algorithms that measure the shortest path between two
Protocol (RIP)	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	Original version of RIP. This is a classful routing protocol, it does not have the ability to
Protocol Version 1	transmit the subnet mask within its updates. RIP v1 imposes the subnet mask on the
(RIPv1)	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	Second version of RIP, additional to Version 1, enables the use of a simple authentication
Protocol Version 2	mechanism to secure table updates. More importantly, RIP 2 supports subnet masks, a
(RIPv2)	critical feature that is not available in RIP (v1).
SAP	Service Access Point.
Session Initiation	SIP is the emerging standard for setting up telephone call, multimedia conferencing, instant
Protocol (SIP)	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	SNMP is the most common method by which network managements applications can
Management Protocol	query a management agent using a supported MIB (Management Information Base).
(SNMP)	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	Up to eight devices can be connected to one ISDN BRI (or PRI) line. The TEI defines, for
Identifier (TEI)	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.
