Contextual bandwidth management of audio/video conference
An information handling system includes a network hardware device and a processor. The network hardware device transmits Internet Protocol (IP) datagram packets. Each of the IP datagram packets includes a respective user datagram protocol (UDP) packet. The processor detects a UDP packet. The UDP packet includes a real-time protocol (RTP) packet. The processor inspects one or more fields of the RTP packet, and determines whether a conferencing application generated the RTP packet. In response to a conferencing application generating the RTP packet, the processor determines whether the RTP packet is a real-time audio/video packet, and determines whether an audio/video session is in-progress. In response to the audio/video session being in-progress, the processor determines a network traffic policy for the RTP packet, and the network hardware device to transmit the UDP packet encapsulating the RTP packet based on the determined network traffic policy.

in response to the number of real-time audio/video packets for the particular application exceeding the threshold number, determining that an audio/video session is in-progress;
in response to the audio/video session being in-progress, determining, by the processor, a network traffic policy for the RTP packet; and
transmitting, by a network hardware device, the UDP packet encapsulating the RTP packet based on the determined network traffic policy.
10. The method of claim 9 , further comprising:
filtering the RTP packet based on a type of application that generated the RTP packet; and
