  • Logical node identification in an information transmission network
    Patent number: 8918824
    Abstract: A system for generating and sending a Logical Node identification signal as part of a data stream is disclosed. The system also includes subscriber stations capable of receiving and extracting Logical Node identification information from a data stream. The subscriber stations create new messages including the Logical Node identification signal and send the message to the transmission network system control, such that switching of data streams to an appropriate channel over the information transmission network is done consistent with the network topology.
    Type: Grant
    Filed: September 7, 2012
    Date of Patent: December 23, 2014
    Assignee: Comcast IP Holdings I, LLC
    Inventors: Yong Ho Son, Nikhil Rajdev
