Publication number: 20200162357Abstract: Systems, methods, and computer-readable media for monitoring traffic in a network include receiving, at an analytics platform connected to the network, one or more encapsulated packet headers from one or more network nodes of the network. From the one or more encapsulated packet headers, at least one or more source addresses of the one or more network nodes which transmitted the encapsulated packet headers, and one or more timestamps at which the one or more encapsulated packet headers were transmitted from the one or more network nodes may be determined. From at least the one or more source addresses and timestamps, network traffic information such as one or more of latency or jitter of data packets transiting through the one or more network nodes may be determined, wherein the one or more encapsulated packet headers may correspond to the data packets transiting through the one or more network nodes.Type: ApplicationFiled: April 22, 2019Publication date: May 21, 2020Inventors: David John Zacks, Vikram Vikas Pendharkar, Peter Geoffrey Jones, Thomas Szigeti, Praveen T.

Publication number: 20200036610Abstract: Presented herein is an exemplified system and method that provides visibility, for traffic analytics, into secured encapsulated packet (e.g., secure VXLAN-GPE packet, a secure metadata-GPE packet or other GPE standards). The exemplified system and method facilitate encryption of traffic in a granular manner that also facilitate the monitoring of said secure traffic in a fabric network in an end-to-end manner throughout the network. Such monitoring can be beneficially used for analytics, performance analysis, and network debugging/troubleshooting.Type: ApplicationFiled: July 24, 2018Publication date: January 30, 2020Inventors: Atri Indiresan, Linda Tin-Wen Cheng, Melvin Tsai, Peter Geoffrey Jones, Da-Yuan Tung, David John Zacks

Publication number: 20190386955Abstract: At a network device configured to control access to a network, a client device authentication request is received from a client device. The request includes identity credentials and a temporary media access control (MAC) address of the client device. The client device is successfully authenticated based on the identity credentials. After authentication, a new MAC address is established in the client device. A data frame is received from at the network device. It is determined whether the client device is using the new MAC address based on the received data frame. If it is determined that the client device is using the new MAC address, the client device is permitted access the network.Type: ApplicationFiled: August 27, 2019Publication date: December 19, 2019Inventors: Brian Eliot Weis, Peter Geoffrey Jones

Patent number: 10171306Abstract: Methods and system are disclosed which can simplify the configuration of a MCEC in a fabric environment such that is may become automatic. Furthermore, centralized identities (such as a host tracking database and/or a network controlled) may be employed to detect the presence of a MCEC. Requiring the creation of direct links between network devices participating in the MCEC may be avoided. Furthermore, logical L2 fabric connectivity (over a L3 fabric underlay) may be utilized to provide dual homing active-active services without additional configuration, as the tracking of peer network devices may be performed in a centralized manner. For example, a host tracking database or a network controller may be employed for peer tracking.Type: GrantFiled: February 26, 2015Date of Patent: January 1, 2019Assignee: Cisco Technology, Inc.Inventors: Nalinaksh M.

Patent number: 10075391Abstract: A method for allocating port assignments for transmitting a reserved network stream across a network node comprises determining a cycle time associated with a network node. The method also comprises establishing, for at least one port of the network node, a plurality of virtual layers associated with the cycle time, wherein each of the plurality of virtual layers is divided into 2n equally-spaced slots per cycle (where n>0). The method further comprises receiving a reserved stream request associated with transmission of a reserved stream across the node, and determining a number of slots required to transmit the reserved stream. The method also comprises assigning one or more slots associated with a port of the network node to the transmission of packets associated with the reserved stream based on the determined number of slots. The method further comprises transmitting the stream according to the slot assignment associated with the port of the network node.Type: GrantFiled: August 28, 2017Date of Patent: September 11, 2018Assignee: Cisco Technology, Inc.Inventors: Norman William Finn, Rong Pan, Hiroshi Suzuki, Linda Tin-Wen Cheng, Peter Geoffrey Jones, Hariprasada Rao Ginjpalli, Rudolph Benedict Klecka
