QoS:
VoIP:
Voice over Internet Protocol (VoIP) is the term used to describe the technology used to provide telephone service over the internet
and/or private data networks using the internet protocol to transmit and receive data. Internet protocol is considered
a "best effort" transmission that is subject to delays. Standard data is usually not affected to a great degree by these minor
delays but VoIP needs to be prioritized for QoS as voice and other real-time transmissions can be severely affected.
VPN
A Virtual Private Network (VPN) is a technology that establishes a private or secure network connection within a public network,
such as the Internet. The network connection appears to the user as a point-to-point circuit without actually involving a permanent
physical connection. VPNs retain the advantages of dedicated private networks but with reduced cost and additional capacity on
demand.
PBX:
A PBX (private branch exchange) is a telephone system within a business that switches calls between internal users on local lines
while allowing all users to share a certain number of external phone lines. Current technology offering VoIP may
refer to the PBX as an IPPBX (See VoIP).
Some Common Technical Terms:
Quality of Service (QoS) is the ability to provide different priorities to different applications on a converged data network (See:Media/Network Convergence). This prioritization is required for real-time applications such as voice (VoIP) and other real-time streaming
multimedia whose quality can be greatly degraded by interruption or delay in the data transmission.
