Publication number: 20240015086Abstract: Some embodiments provide a method for detecting a failure of a layer 2 (L2) bump-in-the-wire service at a device. In some embodiments, the device sends heartbeat signals to a second device connected to L2 service nodes in order to detect failure of the L2 service (e.g., a failure of all the service nodes). In some embodiments, the heartbeat signals are unidirectional heartbeat signals (e.g., a unidirectional bidirectional-forwarding-detection (BFD) session) sent from each device to the other. The heartbeat signals, in some embodiments, use a broadcast MAC address in order to reach the current active L2 service node in the case of a failover (i.e., an active service node failing and a standby service node becoming the new active service node). The unidirectional heartbeat signals are also used, in some embodiments, to decrease the time between a failover and data messages being forwarded to the new active service node.Type: ApplicationFiled: September 19, 2023Publication date: January 11, 2024Inventors: Sami Boutros, Stephen Tan, Rahul Mishra, Kantesh Mundaragi, Jayant Jain, Akhila Naveen

Patent number: 11743172Abstract: Some embodiments provide novel methods for providing different types of services for a logical network associated with an edge forwarding element acting between the logical network and an external network. The edge forwarding element receives data messages for forwarding and performs a service classification operation to select a set of services of a particular type for the data message. The particular type of service is one of multiple types of services that use different transport mechanisms to forward the data to a set of service nodes (e.g., service virtual machines, or service appliances, etc.) that provide the service. The edge forwarding element receives the data message after the selected set of services has been performed and performs a forwarding operation to forward the data message. In some embodiments, the method is also performed by edge forwarding elements that are at the edges of logical network segments within the logical network.Type: GrantFiled: June 17, 2020Date of Patent: August 29, 2023Assignee: VMWARE, INC.Inventors: Pierluigi Rolando, Jayant Jain, Raju Koganty, Kantesh Mundaragi, Yuxiao Zhang, Rahul Mishra, Akhila Naveen

Patent number: 11368387Abstract: Some embodiments facilitate the provision of a service reachable at a virtual internet protocol (VIP) address. The VIP address is used by clients to access a set of service nodes in the logical network. Facilitating the provision of the service, in some embodiments, includes returning a serviced data message to a load balancer that selected a service node to provide the service for the load balancer to track the state of the connection using the service logical forwarding element. To use the service logical forwarding element, some embodiments configure an egress datapath of the service nodes to intercept the serviced data message before being forwarded to a logical forwarding element in the datapath from the client to the service node, and determine if the serviced data message requires routing by the routing service provided as a service by the edge forwarding element.Type: GrantFiled: June 17, 2020Date of Patent: June 21, 2022Assignee: VMWARE, INC.Inventors: Pierluigi Rolando, Jayant Jain, Raju Koganty, Kantesh Mundaragi, Yuxiao Zhang, Rahul Mishra, Akhila Naveen
