Telnet
Port 23 RFC 854, 855
Virtual Network Terminal Services
used for remote access to server resources. Port 80 (TCP), 443 (UDP) - eg Citrix
BUS
is a lan with a central cable to which all nodes connect
Tree Topology
similar to BUS
Ring
CLosed loop technology
Mesh
all nodes are connected to every node

all nodes connected to a central device
Ethernet
IEEE 802.3
Token RIng
IEEE 802.5
FDDI
Fiber Distribute Data Interface - uses two rings, one used other back up 100 Mbps - counter rotating - has been supplanted
MPLS
Multiprotocol Label Switching - refered to a IP VPN - but does not incude encryption services
ISDN
Integrated Services Digital Network - remote access with higher bandwidth (before DSL and cable modems) - at end of life
Point-toPoint Lines
expensive options - connects two end points - high bandwidth fiber cable

multiplexes 24 channels over copper cable - 1.544 Mbps - T2 4xT1, T3 7xT2, T4 6xT3
X.25
allows users and hosts to connect through a model to remote hosts via a packet-switched network - replaced by DSL and ATM
Frame Relay
Economical alternative to circuit-switched networks - uses packet switching technology for WAN Connectivity.
ATM
Asynchronous Transfer Mode - 155Mbps - uses virtual circuits, fixed size frames
SLIP
serial line IP cannot be used for full duplex WAN
MNP
Microsoft Networking Protocol - Echoplex
XDSL
