# Configuring stream speed

The following table lists when to use the Switching service stream speed configuration functions:

To... | Use...
--- | ---
Identify all H.100 streams operating at one specified speed | swiGetStreamsBySpeed
Configure the speed of one or more streams of the H.100 bus | swiConfigStreamSpeed

These functions are used to query and configure the speed of an H.100 stream on an H.100 bus. The speed is specified in millions of bits per second. The functions can also be used to configure parts of the H.100 bus to be compatible with the MVIP
bus.
