Abstract

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.

Claims20

Dependent claims

An information handling system comprising:

a network hardware device to transmit one or more Internet Protocol (IP) datagram packets, each of the IP datagram packets including a respective user datagram protocol (UDP) packet;
and
a processor to communicate with the network hardware device, the processor to:
detect a UDP packet, wherein the UDP packet includes a real-time protocol (RTP) packet;
inspect one or more fields of the RTP packet;
determine whether an conferencing application generated the RTP packet;
in response to the conferencing application generating the RTP packet, determine whether the RTP packet is a real-time audio/video packet;
in response to the RTP packet being the real-time audio/video packet, determine whether a number of real-time audio/video packets for a particular application exceeds a threshold number;
in response to the number of real-time audio/video packets for the particular application exceeding the threshold number, determine that an audio/video session is in-progress;
and
in response to the audio/video session being in-progress, determine a network traffic policy for the RTP packet;
the network hardware device to transmit the UDP packet encapsulating the RTP packet based on the determined network traffic policy.

9 more elements

A method comprising:

detecting, by a processor, a UDP packet, wherein the UDP packet includes a real-time protocol (RTP) packet;
inspecting one or more fields of the RTP packet;
filtering the RTP packet based on a type of application that generated the RTP packet;
providing the RTP packet to different callout drivers based on the type of application;
in response to the type of application being a conferencing application:
providing the RTP packet to a first callout driver;
and
determining whether the RTP packet is a real-time audio/video packet;
in response to the RTP packet being the real-time audio/video packet, determining whether a number of real-time audio/video packets for a particular application exceeds a threshold number;
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, wherein the determined network traffic policy indicates that the RTP packet is prioritized for transmission by the network hardware device;
and
transmitting, by a network device, the UDP packet encapsulating the RTP packet based on the determined network traffic policy.
