Patent number: 11936563Abstract: Some embodiments of the invention provide a new networking data path framework that employs one or more dedicated kernel threads to process network traffic on a host computer executing multiple machines (such as virtual machines or containers). This new framework is referred to as an Enhanced Networking Stack (ENS) in this document. In some embodiments, the dedicated kernel threads execute on dedicated CPU cores (e.g., one kernel thread per CPU core) to proactively poll physical NICs (PNICs) of the host computer and virtual NICs (VNICs) of the machines (e.g., VMs), and to perform packet processing operations on packets received by the host and packets transmitted by the machines. In some embodiments, each PNIC or VNIC is associated with one dedicated kernel thread, in order to avoid synchronization issues between the kernel threads.Type: GrantFiled: May 15, 2021Date of Patent: March 19, 2024Assignee: VMware LLCInventor: Louis Luo

Patent number: 11936640Abstract: Some embodiments provide a method for providing a resource to a particular virtual private cloud that is deployed in a set of datacenters that host multiple virtual private clouds. At a resource issuer, the method receives a resource request from a particular machine deployed in the particular virtual private cloud, the resource request including a first set of cloud-specific data. The method obtains a cloud identifier for the particular machine from a registry service of the particular virtual private cloud that interacts with a datacenter-set cloud service that deploys machines in the datacenter set for different virtual private clouds. The method uses the obtained cloud identifier to obtain a second set of cloud-specific data for the particular machine from the datacenter-set cloud service. Upon determining that the first and second sets of cloud-specific data match, the method authenticates the particular machine and issues the resource for the particular machine.Type: GrantFiled: February 25, 2021Date of Patent: March 19, 2024Assignee: VMware LLCInventors: Chen Dar, Aran Bergman, Alex Markuze, Israel Cidon, Eyal Zohar, Igor Golikov

Publication number: 20240086391Abstract: Systems and methods for inspection and repair of VSAN object metadata. A user-space indirection layer is maintained to map logical addresses of VSAN objects to physical memory addresses of their metadata. Commands may then be sent from the user space to distributed object manager (DOM) clients, with the physical addresses of metadata of objects to be inspected. DOM owners thus may bypass their own indirection layers to retrieve object metadata directly from received user commands. Retrieved information is then used to reconstruct and repair object metadata. Repaired metadata may be written back to the VSAN by transmitting a write request containing the physical address at which the repaired metadata is to be written. DOM owners may be placed in a specified mode in which received I/O instructions are ignored unless they are designated as being for metadata repair purposes, such as by including a physical address.Type: ApplicationFiled: September 8, 2022Publication date: March 14, 2024Applicant: VMware, Inc.Inventors: Kevin Rayfeng LI, Wenguang WANG, Quanxing LIU, Pascal RENAULD, Kiran PATIL

Patent number: 11928062Abstract: Some embodiments provide a method for performing data message processing at a smart NIC of a computer that executes a software forwarding element (SFE). The method determines whether a received data message matches an entry in a data message classification cache stored on the smart NIC based on data message classification results of the SFE. When the data message matches an entry, the method determines whether the matched entry is valid by comparing a timestamp of the entry to a set of rules stored on the smart NIC. When the matched entry is valid, the method processes the data message according to the matched entry without providing the data message to the SFE executing on the computer.Type: GrantFiled: June 21, 2022Date of Patent: March 12, 2024Assignee: VMware LLCInventors: Shay Vargaftik, Alex Markuze, Yaniv Ben-Itzhak, Igor Golikov, Avishay Yanai

Patent number: 11929838Abstract: Some embodiments provide a method for evaluating locations of applications in a multi-cloud network with applications located in different cloud datacenters of one or more cloud providers. The method receives data for flows collected from the cloud datacenters. The data for each flow indicates a source and destination of the flow and applications to which at least one of the source and destination of the flow belong. The method uses network topology data to identify a subset of the flows as egress flows, each of which is charged by a cloud provider at which the flow source is located. Based on data from the cloud providers, the method determines a cost for each of the egress flows and a cost associated with each of the applications. The method provides these costs to users of the network for the users to optimize locations of the applications in the different cloud datacenters.Type: GrantFiled: May 11, 2023Date of Patent: March 12, 2024Assignee: VMware LLCInventors: Madan Singhal, Amol Manohar Vaikar, Ambarish Prashant Pande, Shubhrajyoti Mohapatra, Pratiksha Ishwarlal Gugale, Devraj Narendra Baheti, Prahalad Gowardhan Deshpande, Abhijit Sharma
