Patent number: 12254340Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (I) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane.Type: GrantFiled: January 31, 2023Date of Patent: March 18, 2025Assignee: VMWare LLCInventors: Fenil Kavathia, Anuprem Chalvadi, Yang Ping, Akhila Naveen, Yong Feng, Kantesh Mundaragi, Rahul Mishra, Pierluigi Rolando, Jayant Jain, Raju Koganty

Publication number: 20250080414Abstract: Some embodiments provide a method for configuring a gateway machine in a datacenter. The method receives a definition of a logical network for implementation in the datacenter. The logical network includes at least one logical switch to which logical network endpoints attach and a logical router for handling data traffic between the logical network endpoints in the datacenter and an external network. The method receives configuration data attaching a third-party service to at least one interface of the logical router via an additional logical switch designated for service attachments. The third-party service is for performing non-forwarding processing on the data traffic between the logical network endpoints and the external network. The method configures the gateway machine in the datacenter to implement the logical router and redirect at least a subset of the data traffic between the logical network endpoints and the external network to the attached third-party service.Type: ApplicationFiled: November 19, 2024Publication date: March 6, 2025Inventors: Akhila Naveen, Kantesh Mundaragi, Rahul Mishra, Fenil Kavathia, Raju Koganty, Pierluigi Rolando, Yong Feng, Jayant Jain
