Patent number: 10887212Abstract: The present invention provides method and systems for dynamically mirroring network traffic. The mirroring of network traffic may comprise data that may be considered of particular interest. The network traffic may be mirrored by a mirror service portal from a mirror sender, referred to as a mirror source, to a mirror receiver, referred to as a mirror destination, locally or remotely over various network segments, such as private and public networks and the Internet. The network traffic may be mirrored to locations not involved in the network communications being mirrored. The present invention provides various techniques for dynamically mirroring data contained in the network traffic from a mirror source to a mirror destination.Type: GrantFiled: August 5, 2014Date of Patent: January 5, 2021Assignee: Extreme Networks, Inc.Inventors: David E. Frattura, Richard W. Graham, John Roese

Patent number: 9137101Abstract: A network management and monitoring application employs diagnostic messages for confirming network path connectivity and identifying and locating connectivity faults. Diagnostic messages similar to conventional “ping” and “traceroute” messages traverse the network along a prescribed path for which diagnostic feedback is desired. The application receives and analyzes return messages sent from network entities along the path to ascertain connectivity issues on the path. The application receives layer 3 identifiers such as IP addresses, however performs diagnostic operations such as continuity checks based on layer 2 identifiers such as MAC (Media Access Control) identifiers because certain network entities operate on L2 identifiers and would otherwise evade a continuity check based on layer 3 identifiers.Type: GrantFiled: November 23, 2011Date of Patent: September 15, 2015Assignee: AVAYA INC.Inventors: Srikanth Keesara, David E. Frattura, Deborah E. Fitzgerald, Christopher Monti

Patent number: 8239960Abstract: Systems and methods are provided for preserving the privacy of data contained in mirrored network traffic. The mirrored network traffic may comprise data that may be considered confidential, privileged, private, or otherwise sensitive data. For example, the data payload of a frame of mirrored network traffic may include private Voice over IP (VoIP) communications between users on one or more networks. The present invention provides various techniques for securing the privacy of data contained in the mirrored network traffic. Using the techniques of the present invention, network traffic comprising confidential, privileged, private, or otherwise sensitive data may be mirrored in such a manner as to provide for the privacy of such data over at least a portion if not all of the mirrored communications between the mirror source point and the mirror destination point.Type: GrantFiled: March 26, 2010Date of Patent: August 7, 2012Assignee: Enterasys Networks, Inc.Inventors: David E.

Patent number: 8191107Abstract: A lost contact policy response system and related method for adjusting the operation of one or more network infrastructure devices upon detection of a loss of contact with a policy server function. The response system includes a policy enforcement function (“PEF”), a policy manager function, and either or both of policy set(s) and policy enforcement rule (“PER”) set(s). The PEF implements stored or generated PER set(s). The policy manager function includes a monitoring function and an analysis function. The monitoring function monitors for continuing connectivity or signal exchange contact with a network policy server function. The analysis function selects a designated policy, policy set, PER or PER set, and instructs the PEF to implement the selected policy, PER or set. The policy and/or PER sets may be pre-installed, updated, re-installed, revised, or otherwise changed when and as desired. The related method includes corresponding steps for implementing the operations of the functions described.Type: GrantFiled: March 30, 2010Date of Patent: May 29, 2012Assignee: Enterasys Networks, Inc.Inventors: David E. Frattura, Richard W. Graham

Patent number: 7936770Abstract: A method and apparatus are provided that allows for the representation of a larger number of classes of network traffic and logical queues than is physically available on a per port basis within a network device. A number of logical queues, whose number can match the number of classes of network traffic a network device handles, may be supported across an aggregated set of ports even though the network device has fewer physical queues per port than there are classes of network traffic. The method and apparatus improve the management of network traffic sensitive to time delay and jitter, and further facilitates the operation of these applications in a simultaneous or near simultaneous manner.Type: GrantFiled: March 8, 2006Date of Patent: May 3, 2011Assignee: Enterasys Networks, Inc.Inventors: David E.
