Abstract
A device for supporting a plurality of media conferences includes digital signal processors (DSPs) and a system resource management (SRM) module coupled to the DSPs. Each DSP receives input data packets from conference participants and processes the input data packets to generate output data packets. Each DSP determines whether the media conference is set to an active mode and communicates the output data packets to the conference participants in response to determining that the media conference is set to the active mode. The SRM module allocates a media conference to a first DSP and a second DSP and sets the media conference to the active mode in the first DSP and a stand-by mode in the second DSP. The first DSP communicates output data packets associated with the media conference in response to the SRM module setting the media conference to the active mode in the first DSP. The SRM module sets the media conference to the active mode in the second DSP and de-allocates the media conference from the first DSP, and the second DSP communicates output data packets associated with the media conference in response to the SRM module setting the media conference to the active mode in the second DSP.
