Patent number: 9961197Abstract: The present invention provides a system, method and apparatus for authenticating calls that is a robust Anti-vishing solution. The present invention can identify Caller ID spoofing, verify dialed number to detect man-in-the middle and verify called party against dialed digits to detect impersonation. This solution can handle calls coming from any phone any where with little impact on user experience. Two separate solutions are tailored for smart phones (communication devices capable of running application software) and traditional phones to reduce the impact to user experience while providing robust verification.Type: GrantFiled: January 12, 2015Date of Patent: May 1, 2018Assignee: Avaya Inc.Inventors: Srikrishna Kurapati, Rajesh Mohan, Karthikeyan Sadhasivam, Satyam Tyagi

Patent number: 9614761Abstract: A source network address and port translation (NAPT) mechanism is described that reduces or eliminates the need to log any NAT translations. As described herein, a mapping between a subscriber's private address to a public address and port range is determined algorithmically. Given a particular mapping rule, as specified by the service provider, a subscriber is repeatedly and deterministically mapped to the same public network address and a specific port range for that network address. Once the public address and port range for a subscriber are computed, the particular ports for each session for that subscriber are allocated dynamically within the computed NAT port range on per session basis.Type: GrantFiled: November 2, 2015Date of Patent: April 4, 2017Assignee: Juniper Networks, Inc.Inventors: Sarat Kamisetty, Rajesh Mohan, Suresh Kumar Vinapamula Venkata, Reinaldo Penno

Patent number: 9479597Abstract: A node is configured to receive, from a second node, a request to establish a session; perform, in response to the request, a network address translation (NAT) operation to establish the session, the NAT operation causing a first port block to be allocated to the session, the first port block including a first set of ports via which traffic, associated with the session, is transported; determine that the set of ports are no longer available for the session; determine whether a quantity of times that the first port block has been allocated to the session is greater than a threshold; and retain the first port block, for the session, when the quantity of times that the first port block has been allocated to the session is not greater than the threshold.Type: GrantFiled: August 14, 2015Date of Patent: October 25, 2016Assignee: Juniper Networks, Inc.Inventors: Suresh Kumar Vinapamula Venkata, Rajesh Mohan, Sarat Kamisetty, Reinaldo Penno, Sanjay V.

Patent number: 9479596Abstract: A network device may receive a request from a local device to establish a connection with a another device. The request may include an internal network identifier of the local device. The network device may evaluate a plurality of external network identifiers, associated with the network device based on selected criteria. The network device may also, or alternatively, evaluate the external network identifiers by identifying an external network identifier that is already mapped to, or paired with, the internal network identifier. The network device may select an external network identifier, of the plurality of external network identifiers, based on the evaluation and establish the connection requested by the local device using the internal network identifier and the external network identifier.Type: GrantFiled: August 11, 2014Date of Patent: October 25, 2016Assignee: Juniper Networks, Inc.Inventors: Suresh Kumar Vinapamula Venkata, Rajesh Mohan, Sarat Kamisetty, Reinaldo Penno, Sanjay V.
