VoIP Accelerators Performance Requirements

in
Accelerator products can help enterprises a lot in addressing the performance requirements of all enterprise applications including VoIP. First, Accelerators change the economics of wide area networking by squeezing an average of 100% - 400% more bandwidth with peaks of 1000% depending on traffic mix. This frees up link bandwidth to support high quality VoIP Services - and it does it without expensive WAN upgrades.

Voip Applications

in
VoIP could be applied to almost any voice communications requirement, ranging from a simple inter-office intercom to complex multi-point teleconferencing/shared screen environments, passing through applications like Net2Phone and voice mails.

Network Components

in
The major components of a VoIP network are very similar in functionality to that of a circuit-switched network. VoIP networks must perform all of the same tasks that the PSTN does, in addition to performing a gateway function to the existing public network. Although using different technology and approach, some of the same component concepts that make up the PSTN also create VoIP networks. There are three major pieces to a VoIP network.
  • Media gateways
  • Media gateway/signaling controllers
  • IP network

Media Gateways

Media gateways are responsible for call origination, call detection, analog-to-digital conversion of voice, and creation of voice packets (CODEC functions).
