Secondary channel in multiplexed communication between host computer and smartphone

摘要

Data is communicated between a first computing device and a second computing device over a transport employing a communication protocol in a multiplexed manner. The second computing device also includes wireless communication capabilities. Data is received from a first application and a second application through a first virtual port and a second virtual port, respectively, and packets are generated from the data. Tags corresponding to the first application or the second application are added to each packet. The packets are multiplexed and transmitted over the transport according to the communication protocol. The transmitted packets are de-multiplexed based upon the tags to reconstruct the data corresponding to the first or second application.
