Glossary
PPP
The Point-to-Point Protocol is a standard for transmitting network layer datagrams
over serial point-to-point links. PPP is designed to operate both over asynchronous connections
and bit-oriented synchronous systems.
PPPoE
Point-to-Point Protocol over Ethernet (PPPoE) is a specification for connecting the users on
a LAN to the Internet through a common broadband medium, such as a single DSL or cable
modem line.
PPtP
Point-to-Point Tunneling Protocol (PPtP) is a technology for creating a Virtual Private Network
(VPN) within the Point-to-Point Protocol (PPP). It is used to ensure that data transmitted from
one VPN node to another are secure.
Proxy
A proxy is server located between a client application and a real server. It intercepts requests,
attempting to fulfill them itself. If it cannot, it forwards them to the real server. Proxy servers have
two main purposes: improve performance by spreading requests over several machines and filter
requests to prevent access to specific servers or services.

Pre-Shared Key (PSK), see
Public Key
A public key is used in public key cryptography to encrypt a message which can only be decrypted
with the recipient's private or secret key. Public key encryption is also called asymmetric encryption,
because it uses two keys, or Diffie-Hellman encryption. Also see
QoS
Quality of Service (QoS) defines the performance properties of a network service, including
guaranteed throughput, transit delay, and priority queues. QoS is designed to minimize Latency,
Jitter, Packet Loss, and network congestion, and provide a way of allocating dedicated bandwidth
for high priority network traffic.
The IEEE standard for implementing QoS on wireless networks is currently in-work by the
task group. A subset of

The Remote Authentication Dial-In User Service (RADIUS) provides an authentication and
accounting system. It is a popular authentication mechanism for many ISPs.
