Patent number: 11909584Abstract: Particular embodiments may detect, by a core network, a change in network traffic types from a first network traffic type to a second network traffic type. The core network includes one or more network functionality components. Each of the one or more network functionality components is decomposed into multiple service types. The core network may determine several service instances for deployment in response to the change in the network traffic types. Each of the service instances may belong to one of the multiple decomposed service types. The core network may deploy several service instances to one or more server machines of the core network according to a decomposed service type of a respective service instance.Type: GrantFiled: February 17, 2023Date of Patent: February 20, 2024Assignee: Meta Platforms, Inc.Inventors: Amar Padmanabhan, Praveen Kumar Ramakrishnan, Shaddi Husein Hasan, Anoop Singh Tomar, Evgeniy Makeev, Omar Ramadan, Jiannan Ouyang, Xiaochen Tian, Thomas Romano, Ting Xia, Jagannath Rallapalli, Kuan-Yu Li, Shruti Sanadhya

Patent number: 11522788Abstract: Some embodiments provide a set of one or more network controllers that communicates with a wide range of devices, ranging from switches to appliances such as firewalls, load balancers, etc. The set of network controllers communicates with such devices to connect them to its managed virtual networks. The set of network controllers can define each virtual network through software switches and/or software appliances. To extend the control beyond software network elements, some embodiments implement a database server on each dedicated hardware. The set of network controllers accesses the database server to send management data. The hardware then translates the management data to connect to a managed virtual network.Type: GrantFiled: February 15, 2021Date of Patent: December 6, 2022Assignee: NICIRA, INC.Inventors: Bruce Davie, Anupam Chanda, Benjamin L.

Patent number: 11057277Abstract: Techniques disclosed herein provide an approach for managing aggregation service hierarchies. In some embodiments, a hierarchy of an aggregation service is identified. The hierarchy comprises a plurality of nodes, where a respective node is associated with at least one host computer. The aggregation service places resource consumers based on the nodes. A host computer is assigned as a child host of a leaf node based on a clustering heuristic. The clustering heuristic requires the host computer to have access to at least one resource that is accessible to an existing child host of the leaf node. A resource consumer associated with the leaf node is executed on the host computer.Type: GrantFiled: April 8, 2019Date of Patent: July 6, 2021Assignee: VMWARE, INC.Inventors: Vadim Spivak, Maithem Munshed, Amar Padmanabhan, Michi Mutsuzaki

Patent number: 10552228Abstract: Techniques disclosed herein provide an approach for assigning resource consumers to available resources. In one embodiment, components of a distributed scheduler are organized into a hierarchy, such as a tree. A placement request received at a root scheduler of the hierarchy is propagated down the hierarchy, either to all children or to randomly selected subsets of children of each scheduler in the hierarchy. Leaf schedulers in the hierarchy that receive the request each propagate back up a score indicating the amount of free resources in its corresponding resource bucket. Branch schedulers then compare scores that they receive, and each further propagate one of the received scores, such as the highest score, based on the comparison, until the root scheduler is reached. The root scheduler makes an additional comparison and returns one of the resource buckets in response to the received placement request.Type: GrantFiled: June 20, 2016Date of Patent: February 4, 2020Assignee: VMware, Inc.Inventors: Vadim Spivak, Amar Padmanabhan, Anfernee Yongkun Gui, Badhri Sampathkumar, Luca Castellano, Maithem Munshed, Michi Mutsuzaki, Vui Chiap Lam
