Patent number: 11750446Abstract: Some embodiments provide a method for efficient data message transfer across a hypervisor, service DCN, and containers implementing partner network services. The method allocates memory to a service DCN that operates a set of containers for providing partner network services for data messages received by the service DCN. The service DCN and the containers share the allocated memory and the method stores data messages received by the service DCN in the allocated memory. The method then accesses the data message stored in the shared memory from a set of partner network service containers to perform the partner network services. In some embodiments, the host machine or a process of the host machine on which the service DCN executes also shares the allocated memory. The host machine process, in some embodiments is a kernel process.Type: GrantFiled: March 21, 2022Date of Patent: September 5, 2023Assignee: NICIRA, INC.Inventors: Rahul Mishra, Chidambareswaran Raman, Raju Koganty, Fenil Kavathia

Publication number: 20230185630Abstract: Some embodiments provide a method for clustering a set of data compute nodes (DCNs), which communicate with each other more frequently, on one or more host machines. The method groups together guest DCNs (GDCNs) that (1) execute on different host machines and (2) exchange network data among themselves more frequently, in order to reduce interhost network traffic. The more frequently-communicating GDCNs can be a set of GDCNs that implement a distributed application, GDCNs of a particular tier in a multi-tier network architecture (e.g., a web tier in a three-tier architecture), GDCNs that are dedicated to a particular tenant in a hosting system, or any other set of GDCNs that exchange data among each other regularly for a particular purpose.Type: ApplicationFiled: February 6, 2023Publication date: June 15, 2023Applicants: Nicira, Inc., Nicira, Inc.Inventors: Xin Qi, Fenil Kavathia, Chidambareswaran Raman, Shadab Shah, Raju Koganty, Jingmin Zhou

Publication number: 20230179474Abstract: 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: January 28, 2023Publication date: June 8, 2023Inventors: Akhila Naveen, Kantesh Mundaragi, Rahul Mishra, Fenil Kavathia, Raju Koganty, Pierluigi Rolando, Yong Feng, Jayant Jain

Publication number: 20230168917Abstract: 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: (1) 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. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node.Type: ApplicationFiled: January 31, 2023Publication date: June 1, 2023Inventors: Fenil Kavathia, Anuprem Chalvadi, Yang Ping, Akhila Naveen, Yong Feng, Kantesh Mundaragi, Rahul Mishra, Pierluigi Rolando, Jayant Jain, Raju Koganty

Patent number: 11012351Abstract: The disclosure provides an approach for computing service paths for a service chain identifying a sequence of services. One method includes including information about a plurality of hosts in a heap. Each of the plurality of hosts includes at least one service virtual computing instance (SVCI) configured to provide at least one of the services of the service chain. The information includes, for each of the plurality of hosts, a number of service paths computed for the service chain at the host and one of a number of services provided by unused SVCIs of the host or a number of consecutive services provided by unused SVCIs of the host. The method further includes selecting a host from the heap based on the information. The method further includes generating a first service path for the service chain, the first service path identifying at least one SVCI of the selected host.Type: GrantFiled: February 22, 2019Date of Patent: May 18, 2021Assignee: VMware, Inc.Inventors: Yong Feng, Yanjun Lin, Yang Ping, Pierluigi Rolando, Anuprem Chalvadi, Li Sun, Fenil Kavathia, Raju Koganty

Patent number: 10944673Abstract: Some embodiments provide a method for forwarding a data message. The method performs a lookup to map a set of header fields of the data message to an identifier corresponding to a service that performs non-forwarding processing on data messages. The method uses a dynamically-updated data structure for the identifier to retrieve instructions for forwarding data messages to the service. The method forwards the data message according to the retrieved instructions from the data structure for the identifier.Type: GrantFiled: September 2, 2018Date of Patent: March 9, 2021Assignee: VMWARE, INC.Inventors: Akhila Naveen, Kantesh Mundaragi, Rahul Mishra, Fenil Kavathia, Raju Koganty, Pierluigi Rolando, Yong Feng, Jayant Jain

Patent number: 10897392Abstract: Some embodiments provide a novel method for configuring a service data compute node (DCN) executing on a host computer to perform network services (e.g., firewall, load balancing, intrusion detection, network address translation (NAT), other middlebox services, etc.) for several DCNs executing on the host computer. The method receives, at the service DCN, an identification of a set of container specifications that will be implemented (e.g., will be executed by) the service DCN. The method then retrieves the identified set of container specifications (e.g., container images) from a container repository storing multiple received container specifications. In some embodiments, the container specifications include container images generated by a third party service partner for providing a particular service or set of services and stored in a container repository. The method then instantiates the retrieved containers to provide the identified network services to data messages received at the service DCN.Type: GrantFiled: June 11, 2018Date of Patent: January 19, 2021Assignee: NICIRA, INC.Inventors: Rahul Mishra, Chidambareswaran Raman, Raju Koganty, Fenil Kavathia
