Glossary
Point of Presence (POP)
In Internet terms, the physical site that contains an ISP’s network
equipment. Remote users dial into the POP, authenticate against the ISP’s
customer database, and then gain access to the Internet. ISPs typically have
POPs scattered throughout their service area, so that can customers can dial a
local phone call and avoid paying long- distance charges when accessing the
Internet.
Point-to-Point Protocol (PPP)
The Internet standard for sending network traffic over serial lines, such as
dial-up phone lines. Unlike its predecessor SLIP (Serial Line Internet
Protocol), PPP provides error detection and compression capabilities.
Point-to-Point Tunneling Protocol (PPTP)
A network protocol for linking remote locations over the Internet rather than
over costly long-distance or leased lines. To accomplish this, PPTP
encapsulates other network protocols (such as TCP/IP, IPX, and NetBEUI)
and uses encryption to secure the data sent over the Internet. PPTP was
developed jointly by Microsoft and U.S. Robotics (3Com).
PPPoE
The Point-to-Point over Ethernet protocol provides a connection to the Internet
through a DSL provider. It is also identified as PPPoE.
RiverMaster
A management application running on a Windows NT 4.0 Workstation
computer which communicates with Aurorean Policy Servers and
Aurorean Network Gateways. Using RiverMaster, a network
administrator creates user databases, sets policies for user groups, views
activity logs, and generates usage reports.
