91

SNMP

Simple Network Management Protocol - Port 161, 162 and RFC 1157. designed to manage network infrastructure

92

Telnet

Port 23 RFC 854, 855

93

Virtual Network Terminal Services

used for remote access to server resources. Port 80 (TCP), 443 (UDP) - eg Citrix

94

BUS

is a lan with a central cable to which all nodes connect

95

Tree Topology

similar to BUS

96

Ring

CLosed loop technology

97

Mesh

all nodes are connected to every node

98

Star

all nodes connected to a central device

99

Ethernet

IEEE 802.3

100

Token RIng

IEEE 802.5

101

FDDI

Fiber Distribute Data Interface - uses two rings, one used other back up 100 Mbps - counter rotating - has been supplanted

102

MPLS

Multiprotocol Label Switching - refered to a IP VPN - but does not incude encryption services

103

ISDN

Integrated Services Digital Network - remote access with higher bandwidth (before DSL and cable modems) - at end of life

104

Point-toPoint Lines

expensive options - connects two end points - high bandwidth fiber cable

105

T1

multiplexes 24 channels over copper cable - 1.544 Mbps - T2 4xT1, T3 7xT2, T4 6xT3

106

X.25

allows users and hosts to connect through a model to remote hosts via a packet-switched network - replaced by DSL and ATM

107

Frame Relay

Economical alternative to circuit-switched networks - uses packet switching technology for WAN Connectivity.

108

ATM

Asynchronous Transfer Mode - 155Mbps - uses virtual circuits, fixed size frames

109

SLIP

serial line IP cannot be used for full duplex WAN

110

MNP

Microsoft Networking Protocol - Echoplex

111

XDSL

1.544 - HDSL - two copper twisted pairs.

112

Ethernet

A unit is a frame. Fast Ethernet 802.3u 100Mbps. Ethernet access method is CSMA/CD 100 BAse TX Fast Ethernet - 2 pair Cat 5 UTP or Cat1 STP

113

Unicast

LAN Trasmission Protocol

114

POP#

Runs on Port 110

115

IP Header Protocol Field

ICMP - 1, IGMP - 2, TCP - 6, UDP 17

116

X.400

OSI for message handling

117

Diverse routing

thru split cable or duplicate cable facilities

118

Telenet & Rlogin

Use TCP protocol

119

Screening Router

packet filter based on source & destination filter

120

CHAP

Challenge Hand Authentication Protocol
