Patent number: 11934341Abstract: Distributed computing systems, devices, and associated methods of virtual RDMA switching are disclosed herein. In one embodiment, a method includes intercepting a command from an application in a container to establish an RDMA connection with a remote container on a virtual network. In response to the intercepted command, an RDMA endpoint at a physical NIC of a server is created. The method can also include intercepting another command to pair with a remote RDMA endpoint corresponding to the remote container. The intercepted another command contains data representing a routable network address of the remote RDMA endpoint in the RDMA computer network. Then, the RDMA endpoint created at the physical NIC of the server can be paired with the remote RDMA endpoint using the routable network address of the remote RDMA endpoint.Type: GrantFiled: June 17, 2022Date of Patent: March 19, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Yibo Zhu, Jitendra D.

Publication number: 20230261960Abstract: Techniques are disclosed for identifying faulty links in a virtualized computing environment. Network path latency information is received for one or more network paths in the networked computing environment. Based on the network path latency information, a probable presence of a faulty component is determined. In response to the determination, physical links for a network path associated with the probable faulty component are identified. Information indicative of likely sources of the probable faulty component is received from multiple hosts of the networked computing environment. Based on the identified physical links and information, a faulty component is determined.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Shachar RAINDEL, Jitendra D.

Patent number: 11493978Abstract: Techniques for employing a decentralized sleep management service are described herein. In some instances, each computing device of a group of computing devices periodically shares information about itself with each other computing device of the group. With this information, each computing device within the group that is awake and capable of managing other devices selects a subset of devices to probe. The devices then probe this subset to determine whether the probed devices are asleep. In response to identifying a sleeping device, the probing device takes over management of the sleeping device. Managing the sleeping device involves informing other devices of the group that the sleeping device is being managed, in addition to monitoring requests for services on the sleeping device. In response to receiving a valid request for a service hosted by the sleeping device, the managing device awakens the sleeping device and ceases managing the now-woken device.Type: GrantFiled: February 27, 2017Date of Patent: November 8, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Jacob R. Lorch, Siddhartha Sen, Jitendra D. Padhye, Richard L. Hughes, Carlos Garcia Jurado Suarez

Patent number: 11042501Abstract: Distributed storage systems, devices, and associated methods of data replication are disclosed herein. In one embodiment, a server in a distributed storage system is configured to write, with an RDMA enabled NIC, a block of data from a memory of the server to a memory at another server via an RDMA network. Upon completion of writing the block of data to the another server, the server can also send metadata representing a memory location and a data size of the written block of data in the memory of the another server via the RDMA network. The sent metadata is to be written into a memory location containing data representing a memory descriptor that is a part of a data structure representing a pre-posted work request configured to write a copy of the block of data from the another server to an additional server via the RDMA network.Type: GrantFiled: April 2, 2020Date of Patent: June 22, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Yibo Zhu, Jitendra D.

Patent number: 10055762Abstract: The deep application crawling technique described herein crawls one or more applications, commonly referred to as “apps”, in order to extract information inside of them. This can involve crawling and extracting static data that are embedded within apps or resource files that are associated with the apps. The technique can also crawl and extract dynamic data that apps download from the Internet or display to the user on demand, in order to extract data. This extracted static and/or data can then be used by another application or an engine to perform various functions. For example, the technique can use the extracted data to provide search results in response to a user query entered into a search engine. Alternately, the extracted static and/or dynamic data can be used by an advertisement engine to select application-specific advertisements. Or the data can be used by a recommendation engine to make recommendations for goods/services.Type: GrantFiled: March 12, 2015Date of Patent: August 21, 2018Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Jie Liu, Suman Kumar Nath, Jitendra D.
