Patent number: 11290284Abstract: One or more data packets intended for a workload running on the server are received from an endpoint at a proxy associated with a server. The proxy associated with the server determines whether the one or more data packets intended for the workload are encrypted with a certificate associated with a policy group that includes the workload. The one or more data packets are provided to the workload based on whether the one or more data packets intended for the workload are encrypted with a certificate associated with a policy group that includes the workload.Type: GrantFiled: December 17, 2019Date of Patent: March 29, 2022Assignee: Tigera, Inc.Inventor: Christopher David Liljenstolpe

Publication number: 20210168198Abstract: Metadata associated with a workload is determined. The workload is associated with a consumer of a service. One or more policies associated with the metadata are retrieved. An agent is configured to perform policy-controlled service routing of communications comprising the data packets with respect to the workload based on the one or more policies.Type: ApplicationFiled: January 18, 2021Publication date: June 3, 2021Inventor: Christopher David Liljenstolpe

Publication number: 20210067376Abstract: Measures for routing data packets in a data center network are provided. A packet forwarding function in a server in a data center network is configured to forward data packets to/from virtual systems hosted on that server. The packet forwarding function is configured to make forwarding decisions for received data packets based on the destination internet protocol (IP) address of the received data packet, and forward the data packet at least on the basis of the forwarding decision.Type: ApplicationFiled: May 6, 2020Publication date: March 4, 2021Inventor: Christopher David Liljenstolpe

Patent number: 10298493Abstract: Measures, including methods, systems and computer program products, for use in processing route data in a network comprising a plurality of autonomous systems. At a network device, route data defining at least one route for network traffic which is configured on at least one border network device is received from the at least one border network device. The at least one border network device is located at a border of an autonomous system in the plurality of autonomous systems. The network device processes the received route data according to a set of policies to generate modified route data. The network device transmits at least a part of the modified route data to the at least one border network device. The at least part of the modified route data is operable to instruct the at least one border network device to modify the behavior of the at least one route.Type: GrantFiled: January 30, 2015Date of Patent: May 21, 2019Assignee: Metaswitch Networks LtdInventors: Christopher David Liljenstolpe, Jonathan Eric Hardwick, Jonathan Richard Berger

Patent number: 9800496Abstract: Measures for controlling communication access in a data center network are provided. A packet forwarding function in a server in a data center network is configured to access an access control data store when making forwarding decisions for received data packets which are being routed to/from virtual systems hosted on that server. In response to receipt, at the server, of a setup notification relating to setup of a virtual machine on the server, one or more entries are populated in the access control data store. The entries comprise an internet protocol (IP) address of the virtual system and at least one associated IP address of one or more other communication endpoints.Type: GrantFiled: December 19, 2016Date of Patent: October 24, 2017Assignee: Tigera, Inc.Inventor: Christopher David Liljenstolpe

Patent number: 9584340Abstract: Measures for establishing connectivity in a data center network are provided. A virtual connection is created between a virtual system hosted on a server in a data center network, and a packet forwarding function in that server. Additionally, an entry is populated in a packet forwarding data store in the server, which includes an internet protocol (IP) address of the virtual system and an associated identifier for the created virtual connection. The packet forwarding data store is accessed by the packet forwarding function when making forwarding decisions for received data packets.Type: GrantFiled: May 3, 2016Date of Patent: February 28, 2017Assignee: Tigera, Inc.Inventor: Christopher David Liljenstolpe
