Method and device for filtering media packets

摘要

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.

1. A method comprising:
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 protocol of the packet is supported by the processor; determining, by the video conferencing device, a media stream ID for the packet, the media stream ID of the packet being located by reading a field in the packet at an offset from a header defined by a protocol of the packet; determining, by the video conferencing device, whether the packet includes media based on a length of the packet; sending a request to a Look-up Table memory using the media stream ID as an input value and in parallel with the sending of the request to the Look-up Table memory, determining, by 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, the 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.
