VoIP
Voice over IP (also called VoIP, IP Telephony, and Internet telephony) refers to
technology that enables routing of voice conversations over the Internet or any
other IP network. The voice data flows over a general-purpose packet-switched
network, instead of the traditional dedicated, circuit-switched voice transmission
lines.
NAT
Network Address Translation. A networking protocol that allows network of private
IP address to be set up using a single real IP address.
PPPoE
Point-to-Point Protocol over Ethernet, is a network protocol for encapsulating PPP
frames in Ethernet frames. It is used mainly with cable modem and DSL services.
STUN
Simple Traversal of UDP over NATs, is a network protocol allowing clients behind
NAT (or multiple NATs) to find out its public address, the type of NAT it is behind and
the internet side port associated by the NAT with a particular local port. This
information is used to set up UDP communication between two hosts that are both
behind NAT routers. The protocol is defined in RFC 3489. STUN will usually work well
with non-symmetric NAT routers.
MAC address
Media Access Control address, is a unique code assigned to most forms of
networking hardware. The address is permanently assigned to the hardware, so
limiting a wireless network's access to hardware -- such as wireless cards -- is a
security feature employed by closed wireless networks.
