Abstract:
A method including: receiving, at a video conferencing device, a packet of a video conferencing media stream, the video conferencing device including a processor; determining, by the video conferencing device, whether a length of the packet is sufficiently long to contain media; sending a request to a Look-up Table memory using the media stream ID as an input value while in parallel determining, with the processor, whether the packet is a valid media packet; in response to receiving a destination address in a media processing network from the Look-up Table memory and determining that the packet is a valid media packet, modifying, by the video conferencing device, a header of the packet with the destination address received from the Look-up Table memory; and transmitting, by the video conferencing device, the packet to the modified destination address.
