Publication number: 20230421410Abstract: A network system that includes a first set of network hosts in a first domain and a second set of network hosts in a second domain. Within each of the domains, the system includes several edge switching elements (SEs) that each couple to the network hosts and forward network data to and from the set of network hosts. Within the first domain, the system includes (i) an interior SE that couples to a particular edge SE in order to receive network data for forwarding from the edge SE when the edge SE does not recognize a destination location of the network data and (ii) an interconnection SE that couples to the interior SE, the edge SE, and the second domain through an external network. When the edge SE receives network data with a destination address in the second domain, it forwards the network data directly to the interconnection SE.Type: ApplicationFiled: September 9, 2023Publication date: December 28, 2023Applicant: Nicira, Inc.Inventors: Teemu Koponen, Martin Casado, Pankaj Thakkar, Ronghua Zhang, Daniel J.

Patent number: 11683214Abstract: Systems and methods for managing a network are described. A view of current state of the network is maintained where the current state of the network characterizes network topology and network constituents, including network entities and network elements residing in or on the network. Events are announced that correspond to changes in the state of the network and one or more network elements can be configured accordingly. Methods for managing network traffic are described that ensure forwarding and other actions taken by network elements implement globally declared network policy and refer to high-level names, independently of network topology and the location of network constituents. Methods for discovering network constituents are described, whereby are automatically configured. Routing may be performed using ACL and packets can be intercepted to permit host to continue in sleep mode. The methods are applicable to virtual environments.Type: GrantFiled: August 2, 2020Date of Patent: June 20, 2023Assignee: NICIRA, INC.Inventors: Martin Casado, Keith E. Amidon, Peter J.

Publication number: 20220400088Abstract: In general, the present invention relates to a virtual platform in which one or more distributed virtual switches can be created for use in virtual networking. According to some aspects, the distributed virtual switch according to the invention provides the ability for virtual and physical machines to more readily, securely, and efficiently communicate with each other even if they are not located on the same physical host and/or in the same subnet or VLAN. According other aspects, the distributed virtual switches of the invention can support integration with traditional IP networks and support sophisticated IP technologies including NAT functionality, stateful firewalling, and notifying the IP network of workload migration. According to further aspects, the virtual platform of the invention creates one or more distributed virtual switches which may be allocated to a tenant, application, or other entity requiring isolation and/or independent configuration state.Type: ApplicationFiled: August 21, 2022Publication date: December 15, 2022Inventors: Martin Casado, Paul Ingram, Keith E. Amidon, Peter J. Balland, III, Teemu Koponen, Benjamin L. Pfaff, Justin Pettit, Jesse E. Gross, IV, Daniel J. Wendlandt

Publication number: 20220103452Abstract: Some embodiments provide a method for a network controller that manages several managed forwarding elements. The method receives a request to trace a specified packet having a particular source on a logical switching element. The method generates the packet at the network controller according to the packet specification. The generated packet includes an indicator that the packet is for a trace operation. The method inserts the packet into a managed forwarding element associated with the particular source. The method receives a set of messages from a set of managed forwarding elements that process the packet regarding operations performed on the packet.Type: ApplicationFiled: December 10, 2021Publication date: March 31, 2022Inventors: Igor Ganichev, Pankaj Thakkar, Paul Fazzone, Teemu Koponen, Daniel J Wendlandt
