Publication number: 20230147408Abstract: The present disclosure discloses a system and method for dynamically modifying role based access control for a client based on the activity. Generally, a client device is granted access to a network resource based on a first reputation score assigned to the client device. The activity of the client device is monitored. Responsive to monitoring the activity of the client device, a second reputation score is determined for the client device based on the activity. The access by the client device to the network resource is then modified to be granted based on the second reputation score.Type: ApplicationFiled: January 9, 2023Publication date: May 11, 2023Inventors: Ramesh ARDELI, Hari Krishna KURMALA

Patent number: 10992702Abstract: In example implementations, a method is provided that is executed by a processor. A multiplexed data stream is received over a single transmission control protocol (TCP) connection that uses a SPDY protocol. The multiplexed data stream contains data packets associated with a plurality of different data streams. A plurality of sub-contexts are generated. Each one of the sub-contexts is associated with a different one of the plurality of different data streams. The data packets are demultiplexed from the multiplexed data stream into a respective one of the plurality of sub-contexts. The plurality of different data streams in the respective one of the plurality of sub-contexts are examined to detect a malware.Type: GrantFiled: January 27, 2016Date of Patent: April 27, 2021Assignee: Hewlett Packard Enterprise Development LPInventors: Ramesh Ardeli, Hari Krishna Kurmala

Patent number: 10993169Abstract: Methods and systems are described for intelligently steering client devices operating in an enterprise network system to an appropriate access point based on types of traffic on each client device and/or types of traffic on access points. In particular, client devices may be moved to a different access point when the wireless channel provided by a current access point fails to meet the signal strength requirements of latency sensitive traffic utilized by the client device. Client devices may be further steered to new access points based on load conditions on access points. For example, client devices with low priority traffic sessions may be steered away from access points with high traffic load levels. Accordingly, the methods and systems described herein ensure improved network access for latency sensitive access categories and/or access categories that are considered important to an enterprise system with minimal disruptions to these sessions.Type: GrantFiled: December 4, 2017Date of Patent: April 27, 2021Assignee: Hewlett Packard Enterprise Development LPInventors: Ramesh Ardeli, Hari Krishna Kurmala, Vamsi Kodavanty

Patent number: 10984103Abstract: An example implementation of the present techniques determines, in response to a request to download a resource, whether the resource has previously been determined to comprise malware. Additionally, it is determined, if the resource has previously been determined to comprise malware, whether the resource has changed since the previous determination. Further the request to download the resource is terminated if the resource has not changed.Type: GrantFiled: January 26, 2016Date of Patent: April 20, 2021Assignee: Hewlett Packard Enterprise Development LPInventor: Ramesh Ardeli

Patent number: 10771391Abstract: Examples disclosed herein relate to enforcing a policy to a packet stream based on a classification and a determination that a proxy connection is associated with the packet stream. In the example, the packet stream is received. In this example, a host value is determined for the packet stream. Also, in the example, it is determined whether the packet stream is associated with the proxy connection. Further, in the example, a classification is determined based on the host value. In this example, the policy is enforced for the packet stream based on the classification and the determination that the proxy connection is associated with the packet stream.Type: GrantFiled: November 5, 2015Date of Patent: September 8, 2020Assignee: Hewlett Packard Enterprise Development LPInventors: Ramesh Ardeli, Venkatesan Marichetty, Hari Krishna Kurmala

Patent number: 9998947Abstract: The present disclosure discloses a method and network device for intelligent handling of voice calls from mobile voice client devices. In some embodiments, the network device detects that a load, corresponding to a plurality of client devices associated with an access point, exceeds a particular threshold value. In some embodiments, the network device detects that a call quality for a current ongoing call, corresponding to a first client device associated with an access point, is below a first threshold value. In response, the network device selects a particular client device, of the plurality of client devices associated with the access point, for disassociation with the access point. The network device then causes the particular client device to disassociate with the access point.Type: GrantFiled: September 16, 2016Date of Patent: June 12, 2018Assignee: ARUBA NETWORKS, INC.Inventors: Gopal Agarwal, Ramesh Ardeli, Venkatesh Joshi, Vamsi Kodavanty, Hari Kurmala, Edward Vajravelu
