Most of today’s companies are maximizing their travel budgets and communication requirements by making headache use of videoconferencing as an swap to slope-to-viewpoint meetings. With this decision to take on enterprise-level videoconferencing comes a requirement for bandwidth solutions which are obedient and cost energetic.

Videoconferencing can leverage the existing public telephone network, a private IP network or the Internet. The object bandwidth for interactive video communications is in the 300K to 400K bit/sec per stream range. This includes audio and video as quickly as govern signaling.
The H.323 protocol does not require that two or more endpoints in a session send the same data rate they admit. A low-powered endpoint may lonesome be responsive to encode at a rate of 100K bit/sec, but, because decoding is less processor-intensive, it could decode a 300K bit/sec videostream.
Nevertheless, in videoconferencing, bandwidth is assumed to be symmetrical. In full-duplex networks such as ISDN, Ethernet, ATM and grow obsolete isolation multiplexed networks, knack is expressed as bandwidth in one paperwork, though equal bandwidth is within pro for traffic in the opposite direction.
You dependence to estimate the number of simultaneous sessions your network needs to refrain, and figure out if your network has bandwidth halt-to-fall.
A T-1 bandwidth circuit offers 1.5M bit/sec in each doling out and would be ample bandwidth for two 512K bit/sec or three 384K bit/sec videoconferences, depending re the amount of simultaneous traffic just about the network. Also, make pardon that you have 10/100 switched Ethernet throughout the LAN segments where videoconferencing traffic is received.
Multipoint conference bandwidth (linked to which three or more locations can see and hear one choice) is calculated separately from mitigation-to-improvement sessions. Multipoint can be conducted in either IP or ISDN environments, and some conferencing units will retain both network types.
Multipoint conferencing products may be software-based or accelerated taking into account special hardware, and their configuration can fabricate exchange bandwidth consumption patterns as skillfully as swing user experiences. For example, between an endpoint is used to host a multipoint conference, the maximum bandwidth for any single participant is the bandwidth allocated to that host separated by the number of locations participating. When you need to have on pinnacle of four locations upon a call at the linked time, network-based products are recommended.
If you arbitrate that your IP network can’t handle the subsidiary traffic allied considering rouse video sessions in a compound or converged network deployment, your options are to rely upon circuit switched networks or to deploy postscript IP bandwidth capacity. To lead in determining and acquiring the precise bandwidth to meet your requirements…it’s strongly recommended to create use of a pardon sophisticated consultation promote such as via DS3-Bandwidth.com.
