Glossary

Network Administrator

The person responsible for installing and maintaining a company’s network

equipment, and also insuring that network resources (such as servers and the

applications running on them) are consistently available and performing

well. In terms of Enterasys Networks products, this person physically installs

Aurorean Policy Servers and Aurorean Network Gateways,

distributes Aurorean Client Software

to remote users, and runs

RiverMaster

software on his/her computer to manage the entire VPN.

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.
