Editing Professional video over IP (section)

== Adequate bandwidth ==
Even with packet loss mitigation, video over IP will only work if the network is capable of carrying the content with some reasonable maximum packet loss rate. In practice, this means that video over IP will not work on overloaded networks. Since IP does not of itself offer any traffic guarantees, this must be applied at the network engineering level. One approach to this is the "quality of service" approach which simply allocates sufficient bandwidth to video-carrying traffic that it will not congest under any possible load pattern. Other approaches include dynamic reduction in frame rate or resolution, [[Network Admission Control]], [[Resource Reservation Protocol|bandwidth reservation]], [[traffic shaping]], and [[Quality of service|traffic prioritization]] techniques, which require more complex network engineering, but will work when the simple approach of building a non-blocking network is not possible. See [[Resource reservation protocol|RSVP]] for one approach to IP network traffic engineering.

The [[Pro-MPEG Wide Area Network group]] has done much work on creating a draft standard for interoperable professional video over IP.
