Bandwidth Management

Videoconferencing can put a strain on network resources, especially when large numbers of users are on video calls.  Somebody – and that certainly means IT – must ensure that unified communications do not overwhelm your network and slow other key enterprise applications to a crawl. The fact is, even the most efficiently compressed video takes up bandwidth. Does this mean that videoconferencing requires major new infrastructure investment – more hardware to carry the peak load? Not necessarily. The answer can be purely software-based.

Deter chaos and maintain needed bandwidth for all applications

The solution lies in efficient use of available bandwidth and having policies that determine which users will have highest priority for video calls, how much bandwidth will be reserved for video calls in progress, and how much bandwidth will be guaranteed to other software applications. These policies need to be set centrally, by administrators, and enacted by the videoconferencing system or a governing application. By setting rules, such as the CEO’s video call to the CFO taking priority over any other call, and having the “bandwidth command” application enforce the rules, IT has an intelligent, policy-based approach that scales to thousands of users.

Protect and control

The application, which governs bandwidth used by videoconferencing, should allow the central administrator to:

  • set rules to govern the amount of bandwidth used by audio and video calls
  • specify audio and video call rates based on the class of user, endpoint capabilities, and network conditions
  • apply a limit on the amount of bandwidth that unified communications can monopolize, to control the impact on other applications
  • protect the bandwidth needed by calls in progress to guarantee high quality of experience

Such a software-based approach is able to handle peak loads without significant new network investments, and can support thousands of active video users. Some users, particularly those classified as lower priority, may experience a delay in initiating a call, or have a temporarily reduced image quality, but critical applications and the majority of unified communications can continue unaffected. The scalability of this software-only approach is very cost-effective, and is part of Avistar’s patent-protected, comprehensive videoconferencing technology.
