BreezeMAX Si 4000 CPE
A protocol suite for securing Internet Protocol (IP)
communications by authenticating and encrypting each IP
packet of a data stream.
A shared data area where voice packets can be collected,
stored, and sent to the voice processor in evenly spaced
intervals. Variations in packet arrival time, called jitter, can
occur because of network congestion, timing drift, or route
changes. The jitter buffer, which is located at the receiving end
of the voice connection, intentionally delays the arriving
packets so that the end user experiences a clear connection
with very little sound distortion.
Local Area Network: A group of interconnected computer and
support devices.
A tunneling protocol used to support virtual private networks
(VPNs).
Media Access Control: The lower of the two sub-layers of the
data link layer defined by the IEEE. The MAC sub-layer
handles access to shared media, such as whether token
passing or contention will be used.
Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network and to create and update routing tables and data
structures. MAC addresses are 6bytes long and are controlled
by the IEEE.
Largest size of a data packet or frame that can be sent in one
complete unit over a packet-based computer network
Using multiple antennas in a Wi-Fi device to improve
performance and throughput.
Microsoft version of the Challenge-handshake authentication
protocol, version 2. MS-CHAPv2 provides mutual
authentication between peers by adding a peer challenge upon
the Response packet and an authenticator response on the
Success packet.
