Patent number: 10084680Abstract: A system and method for subscriber aware network monitoring is provided. The method includes: determining subscriber and session data, wherein the subscriber has a non-unique IP (Internet Protocol) address; retrieving identifying data from a packet; and comparing the identifying data with the determined subscriber and session data to determine the subscriber associated with the packet. The system includes: at least one network probe configured to determine subscriber and session data, wherein the subscriber has a non-unique Internet Protocol (IP) address; at least one traffic probe configured to retrieve identifying data from a packet; and a processing module configured to compare the identifying data with the stored subscriber and session data to determine the subscriber associated with the packet.Type: GrantFiled: July 17, 2017Date of Patent: September 25, 2018Assignee: Sandvine Incorporated ULCInventors: David Cameron Dolson, Travis James Willard, Douglas Arthur Fickling, Jeffrey Thomas Begley, Dror Yehuda Shilo

Patent number: 9264942Abstract: A method for managing quality of service (QoS) consists of receiving a packet and identifying at least one application level characteristic of the packet. The method for managing QoS further consists of modifying quality of service parameters of the packet based on the application level characteristic and sending the packet to a destination with modified quality of service parameters. A system for managing QoS includes modules such as a bearer module adapted to review and retrieve data from a packet and a payload packet inspector module adapted to identify at least one application level characteristic of the packet. The system for managing QoS further has a policy enforcement module designed to modify quality of service parameters of the packet based in part on the retrieved data and the at least one application level characteristic.Type: GrantFiled: February 22, 2012Date of Patent: February 16, 2016Assignee: Sandvine Incorporated ULCInventors: Nilanjan Sarkar, Beny Haddad

Patent number: 9210238Abstract: A network data flow management device including: a working packet module configured to store data related to a data flow; at least one network interface connected to the working packet module for receiving and sending data related to data flows; and a processor configured to: receive data from the working packet module and determine if the data flow matches a predetermined protocol; and if the data flow matches the predetermined protocol, send predictive acknowledgments based on the data flow via the network interface. A method for network data flow management including: monitoring a data flow for a predetermined protocol; if the data flow matches the predetermined protocol, saving data relating to the data flow; and creating and sending a predictive acknowledgement packet related to the data flow.Type: GrantFiled: December 21, 2012Date of Patent: December 8, 2015Assignee: Sandvine Incorporated ULCInventor: Scot Loach

Patent number: 8855020Abstract: A system and method for automatically configuring a network so that each switch in the network is aware of the Multiple Spanning Tree Instances (MSTI) of each other switch and the Virtual Local Area Network (VLAN) that each switch uses. This is achieved through the use of controllers connected to each switch. A master switch is elected and the master switch monitors messages to determine if a switch should be using an alternative MISTI. If so, the master switch instructs a switch to use an alternative MSTI. Either a switch or a node connected to the switch may determine which VLAN to use in sending messages, subject to configuration from the controller of the master switch. Messages are periodically sent by each controller to educate other controllers to aid in learning which node is part of a group connected to a switch, the switch in turn connected to a controller.Type: GrantFiled: January 9, 2007Date of Patent: October 7, 2014Assignee: Sandvine Incorporated ULCInventors: Michael Frank Marchetti, David Cameron Dolson

Patent number: 8693328Abstract: A computer based system and method for distributing a global shaper rate implemented across multiple traffic processing devices. A controller distributes credits according to the demand (amount of traffic, or offered load) of each device, in such a way to achieve global targets, including the shaper rate, strict prioritization of traffic, WFQ weights and fairness between cloned channels, iteratively updated as changes occur in the quantity and makeup of the traffic across the devices.Type: GrantFiled: February 19, 2009Date of Patent: April 8, 2014Assignee: Sandvine Incorporated ULCInventors: David Christopher Landry, David Cameron Dolson

Publication number: 20130223207Abstract: The present disclosure provides a system and a method for managing network traffic. The traffic management system has a quality of experience (QoE) measurement module configured to monitor a QoE metric in real-time. A control module is configured to periodically receive the QoE metric and determine a traffic management action based on the QoE metric. A traffic management module is configured to apply the traffic management action to the network traffic.Type: ApplicationFiled: August 7, 2012Publication date: August 29, 2013Applicant: Sandvine Incorporated ULCInventors: Felix-Antoine R. Bouchard, Peter M. Olyjnik, Donald Bowman, Steven J. Flatt, David Cameron Dolson

Patent number: 7571251Abstract: The invention disclosed is a path optimizer for Peer to Peer (P2P) networks. Large amounts of P2P file exchanges increase the costs to maintain a network. Network service providers typically pay for the amount of data they exchange with other network service providers. The present invention examines P2P messages between and within networks and provides a cost efficient path to handle each P2P message.Type: GrantFiled: May 6, 2002Date of Patent: August 4, 2009Assignee: Sandvine Incorporated ULCInventor: Don Bowman
