Patents by Inventor Suresh Muppala

Suresh Muppala 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).

  • Patent number: 9608916
    Abstract: Herein described is a collection of traffic classifiers communicatively coupled to a classification aggregator. Traffic classifiers may use conventional techniques to classify network traffic by application name, and thereafter may construct mappings that are used to more efficiently classify future network traffic. Mappings may associate one or more characteristics of a communication flow with an application name. In a collaborative approach, these mappings are shared among the traffic classifiers by means of the classification aggregator so that one traffic classifier can leverage the intelligence (e.g., mappings) formulated by another traffic classifier.

  • Patent number: 7869366
    Abstract: A method for controlling data rate at an application layer. The method, in a particular implementation, includes identifying an application-layer message corresponding to a network application, wherein the application-layer message is transmitted in a first direction from a first host to a remote host and is operable to cause the remote host to transmit one or more responsive messages to the first host. A queuing delay is computed for the application-layer message and transmission of the application-layer message across a link to the remote host is delayed according to the queuing delay wherein the computed queuing delay is based at least in part on utilization of the link in a direction opposite the first direction of network traffic corresponding to the network application.

  • Patent number: 7742406
    Abstract: Methods, apparatuses and systems directed to the coordinated classification of network traffic. In one implementation, the present invention enables a coordinated network environment for traffic classification where an upstream network device classifies a data flow and adds traffic class information to at least one packet in the data flow. Downstream network devices in the communications path to the destination host can use the traffic class information in the modified packet, bypassing at least some of the local traffic classification operations and thereby reducing CPU utilization. In one implementation, the last downstream network device strips the traffic classification information from the modified packet before it is forwarded to the destination host. Embodiments of the invention reduce or eliminate redundant network traffic classification operations performed by a plurality of network devices in a communications path.
