Patent number: 11909627Abstract: A method and apparatus for routing packets in a network, such as a satellite mesh network. Network nodes maintain network status information (e.g. link availability information) for the entire network. However, the information is maintained to a higher level of precision for some network regions than for others. For example, the network node can be informed of network events in some regions with lower latency than in other regions. Routing information is generated based on the network status information. Multiple different mechanisms can be used to provide network status updates at different levels of precisions. Nodes which generate or relay network status updates can inhibit (e.g. block or delay) passing the updates toward a target node in order to reduce the level of precision of network status information at that target node.Type: GrantFiled: January 4, 2021Date of Patent: February 20, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Mehdi Arashmid Akhavain Mohammadi

Patent number: 11909637Abstract: A method for creating overlay networking constructs to establish network connectivity between virtual routers and remote physical gateways is provided. An orchestrator receives a mapping between tenant network identifiers for multiple tenant networks and overlay network identifiers for multiple overlay networks. The orchestrator attaches a virtual router to a parent logical port of an overlay logical switch for connectivity between a physical gateway and the multiple tenant networks. The orchestrator creates multiple child logical ports that are sub-interfaces of the parent logical port. Each child logical port is uniquely identified by a tenant network identifier. The orchestrator connects multiple child logical switches to the multiple child logical ports according to the received mapping. Each child logical switch is uniquely identified by an overlay network identifier.Type: GrantFiled: July 14, 2021Date of Patent: February 20, 2024Assignee: VMware LLCInventors: Akshay Kale, Anil Lohiya, Fang Peng, Maheedhar Nallapareddy, Jianjun Shen

Patent number: 11909638Abstract: A method is disclosed for autonomously routing data using relay nodes pre-selected from a group of distributed computer nodes based on measured one-way latencies. One-way latencies between a plurality of nodes in a pulse group are automatically measured. A sending bucket of nodes are automatically selected from the pulse group based on the one-way latencies. A receiving bucket of nodes are automatically selected from the pulse group based on the one-way latencies. In response to a command to transfer data from the first node to the second node, a relay node that is both in the first sending bucket and in the first receiving bucket is automatically selected, wherein data is automatically routed from the first node to the second node via the relay node.Type: GrantFiled: April 21, 2021Date of Patent: February 20, 2024Assignee: Syntropy Network LimitedInventors: Jonas Simanavicius, William B.

Patent number: 11909639Abstract: A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.Type: GrantFiled: September 19, 2022Date of Patent: February 20, 2024Assignee: Amazon Technologies, Inc.Inventors: David R.

Patent number: 11909643Abstract: A system for facilitating efficient progression management in a multi-source tracker of a responder device is provided. During operation, the system can maintain, in a memory device of the responder device, a first tracker for all requests and a second tracker for a privileged group of requests. The system can select a first group from a set of groups as the privileged group. If a request from a requesting device cannot be accepted into the first tracker, the system can determine whether the request belongs to the first group based on a header field of the request. If the request belongs to the first group, the system can select the request for accepting into the second tracker. Subsequently, when a respective request belonging to the first group has been accepted, the system can select a second group from the set of groups as the privileged group.Type: GrantFiled: September 13, 2021Date of Patent: February 20, 2024Assignee: Hewlett Packard Enterprise Development LPInventor: Derek Alan Sherlock

Patent number: 11909646Abstract: A congested network link is identified. Applications that are contributing to the congestion are also identified. The contribution of each of the identified applications to the congestion is then determined in order to determine whether the application's usage of the network should be throttled. A control signal is generated in order to indicate to the application that it is to perform an application-specific throttling operation to reduce the network bandwidth consumed by the application. If the application-specific throttling does not sufficiently reduce network congestion, a more aggressive throttling operation is performed.Type: GrantFiled: June 23, 2022Date of Patent: February 20, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Bradley David Rutkowski, Todd Carlyle Luttinen, Sachin Ramakanth Kulkarni, Vijay Rajesh Kumar, Joseph Ryan Warren
