Shunn-Cheng Jang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Flow control for multi-level buffering schemes
    Patent number: 7769016
    Abstract: A system receives data in multiple streams from an upstream device. The system temporarily stores the data in a first buffer and asserts a forward flow control signal when a capacity of the first buffer exceeds a first threshold value. The system reads the data from the first buffer and selectively processes the data based on the forward flow control signal. The system temporarily stores the selectively processed data in a number of second buffers, generates a backward flow control signal when a capacity of one of the second buffers exceeds a second threshold value, and sends the backward flow control signal to the upstream device.
    Type: Grant
    Filed: February 11, 2009
    Date of Patent: August 3, 2010
    Assignee: Juniper Networks, Inc.
    Inventors: Sharada Yeluri, Raymond Scott Chan, Shahriar Ilislamloo, Varkey Paul Alapat, Shunn-Cheng Jang
