Bandwidth requirements for video-conferencing

Bandwidth requirements for video-conferencing Most companies today are maximizing their travel budgets and communication requirements through the intelligent use of videoconferencing as an alteative to face to face meetings. The decision to implement the enterprise-level videoconferencing is a prerequisite for bandwidth solutions that are reliable and effective. Videoconferencing allows the existing public telephone network, the network, a private IP network or the Inteet. The target bandwidth for interactive video communications in 300K to 400K bit / sec per stream range. This includes audio and video and control signals. The H.323 protocol does not require that two or more endpoints in a session to vote the same data they receive. A low-powered endpoint may only be able to encode at a speed of 100K bit / sec, but because decoding is less processor-intensive, which may decoder 300K bit / sec video stream. However, in videoconferencing, it is assumed that the symmetrical bandwidth. In full-duplex networks such as ISDN, Etheet, ATM and time division multiplexed networks, capacity is known as the bandwidth in one direction, even if bandwidth is available for transport in the opposite direction. You need the number of simultaneous sessions your network of support and see if your network bandwidth, end-to-end. A T-1 provides the bandwidth of the circuit 1.5M bit / s in each direction and the bandwidth would be sufficient for two 512K bit / s or three 384K bit / sec videoconferences, depending on the network simultaneously. So, make sure you have 10/100 switched Etheet throughout the LAN segments where videoconferencing traffic is expected. Multipoint conference bandwidth (with which three or more places to see and hear each other) will be calculated separately from point to point meetings. Multipoint can be IP or ISDN environments, and some units of both types of conferences. Multipoint conference software or can be accelerated with special hardware and different pattes of consumption of bandwidth as well as the experience of other users. For example, if an endpoint is used to produce multi-point conference, the maximum bandwidth for each subscriber, the bandwidth that host divided by the number of participating sites. If you have more than four points on a call at the same time, based on networking products are recommended. If you decide that your IP network can not communicate with the additional traffic associated with video sessions, live in a merger or a convergence of the distribution network, the options are to rely on circuit networks or the provision of additional IP capacity bandwidth.
