Network stream identification for open FaceTime

摘要

A method and apparatus of a device that distinguishes multiplexed media and signaling data traffic is described. In an exemplary embodiment, the device receives, on a single port, a packet of the multiplexed data traffic, where the multiplexed data traffic includes a plurality of packets and each of the plurality of packets is one of a media packet and an encapsulated signaling packet. The device further examines an initial data element of a header of the received packet to determine if the received packet is one of a media packet and a signal packet. The device further forwards the packet to a corresponding module for further processing based on the examining.

主权项

1. A non-transitory machine-readable medium having executable instructions to cause one or more processors to perform a method of distinguishing multiplexed media and signaling data traffic, the method comprising:
receiving, on a single port, a packet of the multiplexed data traffic, wherein the multiplexed data traffic includes a plurality of packets and each of the plurality of packets is one of a media packet or a signaling packet, each signaling packet being a virtual transport packet; examining an initial data element of a header of the received packet to determine if the packet is one of a media packet or a signal packet wherein the initial data element is a first bit of the header of the packet; forwarding the packet to a corresponding module for further processing based on the examining.
