Publication number: 20240064085Abstract: Techniques are provided herein for determining a routing path for application traffic based on historic application telemetry and current network telemetry. The techniques comprising determining current metrics for a set of potential paths between an edge device and an application endpoint associated with an application, generating, from the current metrics, a link score for individual paths in the set of potential paths, receiving application status data generated from historic telemetry data associated with the application and the set of potential paths, generating, from the application status data, an application score for individual paths in the set of potential paths, and determining, as a function of the link score and the application score for individual paths in the set of potential paths, a selected path to be used in communications between the edge device and the application endpoint.Type: ApplicationFiled: November 17, 2022Publication date: February 22, 2024Inventors: Syed Arslan Ahmed, Rahul Ramachandran, Jegan Kumar Somi Ramasamy Subramanian, Nagarajan Venkatesan

Publication number: 20230412483Abstract: Techniques for sharing the probing of software-as-a-service clouds among a cluster of routers are described herein. The techniques may include establishing a first path between a cluster of routers and an application infrastructure. Establishing a second path between the cluster of routers and the application infrastructure. Designating a first router in the cluster of routers to send probes over the first path to the application infrastructure. Designating a second router in the cluster of routers to send probes over the second path to the application infrastructure. Distributing, by the first router and to the cluster of routers, first routing performance data indicating a performance of the first path when communicating with the application infrastructure over the first path, distributing, by the second router and to the cluster of routers, second routing performance data indicating a performance of the second path when communicating with the application infrastructure over the second path.Type: ApplicationFiled: July 18, 2022Publication date: December 21, 2023Inventors: Balaji Sundararajan, Vivek Agarwal, Jegan Kumar Somi Ramasamy Subramanian, Gokul Krishnan, Giorgio Valentini, Venkatraman Venkatapathy

Patent number: 10123225Abstract: In general, this disclosure describes usage monitoring techniques. In one example, a method comprises storing, by a monitoring device that performs usage monitoring for at least one packet flow that traverses an access network by which subscriber devices access a packet data network, data indicating an amount of unused granted service units for the at least one packet flow that is unused as of a policy rule deactivation time for one or more policy rules matched by the at least one packet flow. The monitoring device further reactivates the usage monitoring for the at least one packet flow at a policy rule reactivation time for the one or more policy rules matched by the at least one packet flow based on an updated amount of granted service units, wherein the updated amount of granted service units are based on the data indicating the amount of unused granted service units.Type: GrantFiled: September 29, 2015Date of Patent: November 6, 2018Assignee: Juniper Networks, Inc.Inventors: Ashish Jain, Anand Narayanan Rao, Prasad Chigurupati, Jegan Kumar Somi Ramasamy Subramanian

Patent number: 9602675Abstract: In general, techniques are described for facilitating usage monitoring control in mobile networks. A mobile gateway comprising one or more processors and a memory may be configured to perform the techniques. The one or more processors may be configured to transmit a usage monitoring report indicative of usage of a service provided via a session for which usage monitoring was previously activated. The memory may be configured to store a monitoring key that was configured as a result of activating the usage monitoring for the service. The one or more processors may also be configured to, in response to the indication to deactivate the usage monitoring, remove the monitoring key that was configured as a part of activating the usage monitoring for the session.Type: GrantFiled: November 2, 2015Date of Patent: March 21, 2017Assignee: Juniper Networks, Inc.Inventors: Jegan Kumar Somi Ramasamy Subramanian, Prasad Chigurupati

Patent number: 9571663Abstract: In general, techniques are described for facilitating usage monitoring control in mobile networks. A mobile gateway comprising one or more processors may be configured to perform the techniques. The one or more processors are configured to establish a session by which a mobile device is to access a service, and in response to receiving an indication to activate a charging rule having an incomplete indication to activate usage monitoring with respect to the service provided via the session, rejecting the charging rule.Type: GrantFiled: January 28, 2016Date of Patent: February 14, 2017Assignee: Juniper Networks, Inc.Inventors: Jegan Kumar Somi Ramasamy Subramanian, Prasad Chigurupati

Patent number: 9331948Abstract: An example method is provided and includes receiving a request from a mobile node for an Internet protocol (IP) address and establishing a point-to-point (PPP) link for the mobile node. The method also includes provisioning a first tunnel associated with a first communication flow for the mobile node, and provisioning a sub-tunnel with the first tunnel for a second communication flow. The second communication flow is associated with a high priority type of data to be transported on the sub-tunnel. In more specific embodiments, a call admission control (CAC) mechanism is used to establish the sub-tunnel with the first tunnel for the second communication flow. Additionally, an inner label is installed in a header of a packet associated with the second communication flow in order to identify the sub-tunnel.Type: GrantFiled: October 16, 2013Date of Patent: May 3, 2016Assignee: CISCO TECHNOLOGY, INC.Inventors: Balaji Venkat Venekataswami, Kowsalya Subramanian, Jegan Kumar Somi Ramasamy Subramanian, Manikandan Dhayalan, Rajesh Kumar Andhavaram, Girish Sivasubramanian
