IPX Address
The network layer address for the IPX protocol, which contains a 4-byte network
number (unique for each LAN segment and frame type combination), the 6-byte
MAC address of the device, and the 2-byte socket number that maps to the particular
application in the device.
IPX Network Number
A unique identifier for an IPX network, which is also the beginning 4-bytes of a 12-
byte IPX address. It is unique for each LAN segment and frame type combination.
IPX RIP
The IPX routing protocol, which is used for exchanging and maintaining the IPX
routing table with its neighbor routers.
IPX SAP
IPX Service Advertising Protocol, used for exchanging server tables among IPX SAP
agents. It is similar to IPX RIP. For example, it will broadcast its SAP table either
periodically or whenever it detects a change, and it responds to SAT table queries.
LAN & WAN
Local Area Network & Wide Area Network. Common LAN technologies include
Ethernet, Token Ring, Fast Ethernet. WAN technologies include analog modem,
leased lines, ISDN, frame relay, and ATM.
Multilink
A protocol for utilizing multiple connections for one single communication. Each
connection can be an async modem connection, a PPP leased line, a frame relay
DLCI, or an ISDN B channel connection. Most common multilink applications are as
follows: (1) back-up: when the “primary” PPP connection such as based on frame
relay or leased line is down, a secondary back-up ISDN or modem connection will be
set up automatically to take over the communication; (2) load-sharing over the 2
ISDN B channels: to allow data to be communicated over two ISDN B-channels
simultaneously in order to achieve higher combined data throughput; (3) overflow:
when the traffic load on a primary B channel connection exceeds a certain predefined
threshold, a secondary ISDN connection will be set up automatically, until the traffic
load falls below the low threshold for some duration.
Ping
A utility that can be used to send an echo packet to a remote device (expecting the
same packet to be echoed back if the destination and the network are functioning
properly). This is often used to check if a remote device is reachable or not, and what
the round trip delay is. Some variation of the utility also provide detailed routing
information such as which intermediate routers the echo packet has to go through, so
that if the packet does not come back, the break in the path can easily be identified.
PPP
Point-To-Point Protocol, one that is frequently used in leased line, dial-up, or ISDN
connections.
