Patent number: 11929920Abstract: Described herein are systems, methods, and software to manage processing queue allocation based on addressing attributes of an inner packet. In one implementation, a first gateway identifies processing queues at a second gateway and assigns a unique flow label to each of the processing queues. The first gateway further receives a packet from a computing node that is directed toward the second gateway. The first gateway hashes addressing information in the packet to select a flow label, encapsulates the packet with the flow label in the outer encapsulation header for the encapsulated packet, and forwards the packet toward the second gateway.Type: GrantFiled: September 7, 2021Date of Patent: March 12, 2024Assignee: VMware LLCInventors: Bhargav Puvvada, Sourabh Bhattacharya, Awan Kumar Sharma

Patent number: 11916876Abstract: A method includes selecting one or more green addresses, each being a different IP address from a block of IP addresses, associating the green addresses with the IP address of the server, and receiving a packet from a client directed to an IP address of the block of IP addresses. It is determined whether the destination address matches the one or more green addresses or is a yellow address. When determined that the destination address matches the one or more green addresses, the packet is sent to the IP address associated with the matching green address, bypassing any DPI. Otherwise, the packet is sent to a scrubber to analyze the packet using DPI and handle the packet or perform a redirection of the client. The redirection causes subsequent requests from the client to be sent to the IP address associated with the green address, bypassing any DPI.Type: GrantFiled: June 1, 2023Date of Patent: February 27, 2024Assignee: Arbor Networks, Inc.Inventor: Brian St. Pierre

Patent number: 11909626Abstract: In example embodiments, a shortest path first-based isolation trace function is provided to determines what switchable elements need to be closed to stop flow of a quality to a location in an infrastructure model arranged as a network. The shortest path first-based isolation trace function may perform shortest-path traces from the location to each source. For each successful shortest-path trace finding one or more switchable elements, the first switchable element encountered on the path of the trace is added to a solution set, and marked as active to prevent further traversal in subsequent shortest-path traces. When all the shortest-path traces are complete, the solution set may be returned as a result. If no switchable element is found on a path of one of the shortest-path traces, it may be concluded that the location cannot be isolated and such conclusion returned as the result instead of the solution set.Type: GrantFiled: January 28, 2022Date of Patent: February 20, 2024Assignee: Bentley Systems, IncorporatedInventors: Michael Tajmajer, Michael Carlisle, Alfredo Contreras

Patent number: 11870682Abstract: A method for communication includes partitioning local links in a subnetwork of a packet data network into at least first and second groups. For each local link that connects a first upper-tier switch to a first lower-tier switch in the subnetwork, a corresponding detour route is defined, passing through a first local link belonging to the first group from the first upper-tier switch to a second lower-tier switch, and from the second lower-tier switch over a second local link to a second upper-tier switch, and from the second upper-tier switch over a third local link belonging to the second group to the first lower-tier switch. Upon a failure of the local link connecting the first upper-tier switch to the first lower-tier switch, data packets arriving from the network at the first upper-tier switch are rerouted to pass via the corresponding detour route to the first lower-tier switch.Type: GrantFiled: June 22, 2021Date of Patent: January 9, 2024Assignee: MELLANOX TECHNOLOGIES, LTD.Inventors: Tamir Ronen, Josef Yallouz

Patent number: 11789689Abstract: An audio processing plug-in shim operates in conjunction with a plug-in host application executing on a computing device. The plug-in shim receives a stream of digital audio from the plug-in host application and transmits the digital audio to a network service executing in a network accessible remote distributed computing environment. The network service receives the digital audio and routes the digital audio to one or more audio processing plug-ins, also executing in the distributed computing environment. The audio plug-ins process the digital audio, such as by applying digital signal processing techniques to the digital audio, and return processed audio to the network service. The network service returns the processed audio to the plug-in shim executing on the remote computing device. The plug-in shim, in turn, receives the processed audio from the network service and provides the processed audio to the plug-in host application.Type: GrantFiled: January 19, 2018Date of Patent: October 17, 2023Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Jonathan Andrew Soifer, Anchit Koul, Jeffrey Song Zhu

Patent number: 11784922Abstract: A method for offloading multicast replication from multiple tiers of edge nodes implemented by multiple host machines to a physical switch is provided. Each of the multiple host machines implements a provider edge node and a tenant edge node. One host machine among the multiple host machines receives a packet having an overlay multicast group identifier. The host machine maps the overlay multicast group identifier to an underlay multicast group identifier. The host machine encapsulates the packet with an encapsulation header that includes the underlay multicast group identifier to create an encapsulated packet. The host machine forwards the encapsulated packet to a physical switch of the network segment. The physical switch forwards copies of the encapsulated packet to tenant edge nodes at one or more ports that are determined to be interested in the underlay multicast group identifier.Type: GrantFiled: July 3, 2021Date of Patent: October 10, 2023Assignee: VMWARE, INC.Inventors: Senthilkumar Karunakaran, Subin Cyriac Mathew, Stephen Tan, Meenakshi Sundaram Selvaraj, Chidambareswaran Raman
