Patent number: 11968096Abstract: Computer-implemented methods, media, and systems for inter-cluster automated failover and migration of containerized workloads across edges devices are disclosed. One example method includes monitoring telemetry data received from a first software defined wide area network (SD-WAN) edge device that has a workload scheduled, where the telemetry data includes at least one of a health status of the workload or multiple runtime context elements at the first SD-WAN edge device. It is determined that a failure associated with either the first SD-WAN edge device or the workload occurs. A mode of the failure is determined. A remediation process based on the determined mode of the failure and a current state of the workload is performed.Type: GrantFiled: September 14, 2022Date of Patent: April 23, 2024Assignee: VMware, Inc.Inventors: Raunak Ravindra Singwi, Daniel Beveridge, Erol Aygar, Nilanjan Daw, Sairam Veeraswamy

Publication number: 20240118800Abstract: Systems and methods are described for providing a graphical user interface (“GUI”) for migrating workloads in a system. The GUI can display the locations of edge devices in the system and workloads running on the edge devices. A user can drag a workload from one edge device to another in the GUI, and in response the system can schedule the workload to be migrated accordingly. Before the migration is performed, the GUI can calculate a change in computing resource usage at both edge devices. The GUI can display the usage data and prompt the user to confirm the migration. If the user confirms, the workload can be deployed at the target edge device and removed from the source edge device.Type: ApplicationFiled: December 7, 2022Publication date: April 11, 2024Inventors: EROL AYGAR, Megha Bansal, Akhilesh Kumar, Pranay Pareek, Sairam Veeraswamy

Patent number: 11909815Abstract: Some embodiments provide a method of implementing context-aware routing for a software-defined wide-area network, at an SD-WAN edge forwarding element (FE) located at a branch network connected to the SD-WAN. The method receives, from an SD-WAN controller, geolocation route weights for each of multiple cloud datacenters across which a set of application resources is distributed. The application resources are all reachable at a same virtual network address. For each of the cloud datacenters, the method installs a route for the virtual network address between the branch network and the cloud datacenter. The routes have different total costs based at least in part on the geolocation metrics received from the SD-WAN controller. The SD-WAN edge FE selects between the routes to establish connections to the set of application resources.Type: GrantFiled: June 6, 2022Date of Patent: February 20, 2024Assignee: VMware LLCInventors: Santosh Pallagatti Kotrabasappa, Abhishek Goliya, Sajan Liyon, Sairam Veeraswamy, Sumit Mundhra

Publication number: 20240039804Abstract: Computer-implemented methods, media, and systems for automating secured deployment of containerized workloads on edge devices are disclosed. One example computer-implemented method includes receiving, by a software defined wide area network (SD-WAN) edge device and from a remote manager, resource quotas for a compute service to be enabled at the SD-WAN edge device. Pre-deployment sanity checks are performed by confirming availability of resources satisfying the resource quotas, where the resources are at the SD-WAN edge device. In response to the confirmation of the availability of resources satisfying the resource quotas, one or more security constructs are set up to isolate SD-WAN network functions at the SD-WAN edge device from the compute service at the SD-WAN edge device. The compute service is attached to a SD-WAN network by the SD-WAN edge device. An acknowledgement that the compute service is enabled at the SD-WAN edge device is sent to the remote manager.Type: ApplicationFiled: September 14, 2022Publication date: February 1, 2024Inventors: EROL AYGAR, MARGARET NATASHA DREW, MARK PEEK, DANIEL BEVERIDGE, RAUNAK RAVINDRA SINGWI, NILANJAN DAW, PRANAY PAREEK, SAIRAM VEERASWAMY, AMARNATH RAGHUNATHAN

Publication number: 20230403319Abstract: Some embodiments provide a method of implementing capacity-aware load balancing across a set of data compute nodes (DCNs) by reducing latency for the set of DCNs. From the set of DCNs, the method identifies (1) a first subset of DCNs including DCNs that have a latency that is higher than an average latency computed for the set of DCNs and (2) a second subset of DCNs including DCNs that have a latency that is lower than the average latency computed for the set of DCNs. For each DCN in the first subset of DCNs, the method assigns to the DCN a weight value that corresponds to a target latency computed for the set of DCNs. Based on the assigned weight values for the first subset of DCNs, the method computes an excess weight value to be redistributed across the second subset of DCNs. The method redistributes the computed excess weight value across the second subset of DCNs.Type: ApplicationFiled: July 28, 2023Publication date: December 14, 2023Inventors: Sachin Pandey, Rohan Gandhi, Sreeram Iyer, Santosh Pallagatti Kotrabasappa, Sairam Veeraswamy

Publication number: 20230396538Abstract: Some embodiments provide a method for implementing context-aware routing for a software-defined wide-area network (SD-WAN). The method is performed at a particular SD-WAN edge forwarding element (FE) connected to a particular cloud datacenter. The method receives a message specifying a weight for a virtual network address associated with a set of application resources distributed across multiple cloud datacenters including the particular cloud datacenter. The method converts the specified weight into a route weight for the SD-WAN. The method provides the converted route weight to a set of SD-WAN edge FEs connected to a set of branch networks, and each SD-WAN edge FE in the set of SD-WAN edge FEs uses the provided route weight to calculate a total cost for routing data messages directed to the virtual network address to the particular cloud datacenter.Type: ApplicationFiled: June 6, 2022Publication date: December 7, 2023Inventors: Santosh Pallagatti Kotrabasappa, Abhishek Goliya, Sajan Liyon, Sairam Veeraswamy, Sumit Mundhra

Publication number: 20230370386Abstract: In some embodiments, a method receives a set of packets for a flow and determines a set of features for the flow from the set of packets. A classification of an elephant flow or a mice flow is selected based on the set of features. The classification is selected before assigning the flow to a network resource in a plurality of network resources. The method assigns the flow to a network resource in the plurality of network resources based on the classification for the flow and a set of classifications for flows currently assigned to the plurality of network resources. Then, the method sends the set of packets for the flow using the assigned network resource.Type: ApplicationFiled: July 25, 2023Publication date: November 16, 2023Inventors: Santosh PALLAGATTI KOTRABASAPPA, Sairam VEERASWAMY, Abhishek GOLIYA, Abbas MOHAMED

Publication number: 20230315593Abstract: Techniques for implementing RDMA-based recovery of dirty data in remote memory are provided. In one set of embodiments, upon occurrence of a failure at a first (i.e., source) host system, a second (i.e., failover) host system can allocate a new memory region corresponding to a memory region of the source host system and retrieve a baseline copy of the memory region from a storage backend shared by the source and failover host systems. The failover host system can further populate the new memory region with the baseline copy and retrieve one or more dirty page lists for the memory region from the source host system via RDMA, where the one or more dirty page lists identify memory pages in the memory region that include data updates not present in the baseline copy. For each memory page identified in the one or more dirty page lists, the failover host system can then copy the content of that memory page from the memory region of the source host system to the new memory region via RDMA.Type: ApplicationFiled: June 7, 2023Publication date: October 5, 2023Inventors: Keerthi Kumar, Halesh Sadashiv, Sairam Veeraswamy, Rajesh Venkatasubramanian, Kiran Dikshit, Kiran Tati
