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.
