A method and system for automatically allocating bandwidth on a network bus in an audio/visual network. The present invention implements an intelligent process to automatically make adequate bus bandwidth available when a request for a connection (e.g., a communication channel used to transfer data) between a source device and a sink device is received. First, the present invention determines whether a communication channel is already allocated to the source device, and if so, the connection between the source device and the sink device is made using an overlay of the existing communication channel. Otherwise, the present invention compares the required bus bandwidth capacity for the source device with the available bus bandwidth capacity. Using voluntary and forced load shedding techniques, the present invention deallocates bus bandwidth capacity allocated to one or more of the devices on the audio/visual network if the available bus bandwidth capacity is less than the required bus bandwidth capacity. The present invention allocates a new channel between the source device and the sink device when the available bus bandwidth capacity is greater than or equal to the required bus bandwidth capacity. |
