Patent number: 11128550Abstract: Some embodiments of the invention provide a method for gathering data for logical network traffic analysis by sampling flows of packets forwarded through a logical network. Some embodiments are implemented by a set of network virtualization controllers that, on a shared physical infrastructure, can implement two or more sets of logical forwarding elements that define two or more logical networks. In some embodiments, the method (1) defines an identifier for a logical network probe, (2) associates this identifier with one or more logical observation points in the logical network, and (3) distributes logical probe configuration data, including sample-action flow entry data, to one or more managed forwarding elements that implement the logical processing pipeline at the logical observation points associated with the logical network probe identifier.Type: GrantFiled: November 1, 2019Date of Patent: September 21, 2021Assignee: NICIRA, INC.Inventors: Romain F. Lenglet, Rajiv Ramanathan, Jun Xiao

Patent number: 10797963Abstract: A graphical user interface (“GUI”) allows for the creation of custom key performance indicators (“KPIs”) for real-time analysis of network telemetry events. The GUI can include options for defining variables based on event attributes. These can correspond to events that exist in input telemetry streams at a stream processor. The GUI can allow creation of a formula based on these variables. An aggregation section specifies how the output of the formula is aggregated. This can be based on group, aggregation function, and time period. A manager process causes the stream processor to apply the custom KPI definition to real-time input streams. An output KPI stream can then be routed to a destination for analysis.Type: GrantFiled: September 7, 2019Date of Patent: October 6, 2020Assignee: VMware, Inc.Inventors: Aditya Gudipati, Rakesh Misra, Manu Bansal, Srikanth Hariharan, Ben Basler, Rajiv Ramanathan, Rohan Agarwal

Publication number: 20140355415Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for semi-centralized routing. In one aspect, a computer-implemented method receives a network protocol packet at a router adapted for routing data packets to one or more additional routers. The network protocol packet conforms to a routing protocol that provides distributed routing computation. The method also sends the network protocol packet, through a controller, to a selected one of a plurality of route control servers. The method also processes the network control packet at the selected route control server to generate a routing computation result that conforms to the routing protocol. The method also generates routing information based on the routing computation. The routing information conforms to a control protocol that provides centralized routing computation. The method also sends the routing information to the router for routing of data packets based on the control protocol.Type: ApplicationFiled: August 14, 2014Publication date: December 4, 2014Inventors: Subhasree Mandal, Subbaiah Venkata, Leon Poutievski, Amit Gupta, Min Zhu, Rajiv Ramanathan, James M.
