Publication number: 20210260489Abstract: Session participation in online content streams or activities like multiplayer games is enhanced through management of session tracking and automated queuing of players via a central system between host/streamer client device and guest player client devices. Spectators viewing a content stream or waiting to join a multiplayer activity over a network via a game/streaming service request to be placed in a queue to participate in a session of the content stream or activity as guest players with the host/streaming user. Sessions are tracked to determine start and end events. Sets of prior guest players are removed from sessions when the sessions end, and sets of queued spectators are automatically added to the start of a new session of the content stream or activity as guest players. Queuing may be automatically prioritized for users based on user characteristics, and guest players removed at the end of sessions may be automatically re-queued.Type: ApplicationFiled: April 26, 2021Publication date: August 26, 2021Applicant: Microsoft Technology Licensing, LLCInventors: Ruben Omar Cardona Cruz, Keith R.

Patent number: 11102119Abstract: Various systems, processes, and products may be used to filter multicast messages in virtual environments. In one implementation, a multicast filtering address is received by a network adapter from at least one of a number of virtual machines of a computer system. Responsive to receiving the multicast filtering address, a determination is made whether a multicast filtering store of the network adapter is full. Responsive to determining that the multicast filtering store of the network adapter is full, the multicast filtering address is stored in a local filtering store of the at least one virtual machine.Type: GrantFiled: July 27, 2019Date of Patent: August 24, 2021Assignee: International Business Machines CorporationInventors: Omar Cardona, James B.

Patent number: 11082399Abstract: A method of communicating data traffic including data packets through a virtual switch on a host device is provided. The data traffic flowing through the virtual switch is monitored. The data traffic includes at least virtual machine data traffic flowing to and from virtual machine processes on the host device and host data traffic flowing to and from host operating system processes on the host device. Each of the data packets are designated as virtual machine data traffic or host data traffic based on an evaluation of the Media Access Controller (MAC) address of each of the one or more data packets of the monitored data traffic. Virtual machine data traffic is directed through a packet processor as the virtual machine data traffic traverses the virtual switch. Host data traffic is directed to bypass the packet processor as the host data traffic traverses the virtual switch.Type: GrantFiled: August 10, 2018Date of Patent: August 3, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Alexander Malysh, Omar Cardona, Madhan Sivakumar, Alireza Dabagh

Publication number: 20210105221Abstract: Embodiments of network processing resource management in computing devices are disclosed therein. In one embodiment, a method includes receiving a request from a network interface controller to perform network processing operations at a first core of a main processor for packets assigned by the network interface controller to a queue of a virtual port of the network interface controller. The method also includes determining whether the first core has a utilization level higher than a threshold when performing the network processing operations to effect processing and transmission of the packets. If the first core has a utilization level higher than the threshold, the method includes issuing a command to the network interface to modify affinitization of the queue from the first core to a second core having a utilization level lower than the threshold.Type: ApplicationFiled: September 25, 2020Publication date: April 8, 2021Inventors: Dmitry Malloy, Alireza Dabagh, Gabriel Silva, Khoa To, Omar Cardona, Donald Stanwyck

Publication number: 20200322242Abstract: A packet monitoring application instantiated on a server hosting a virtualized network stack is utilized to track data packet propagations and drops at each component within the network stack to reduce the amount of time to identify a root cause for latency issues. The packet monitoring application can be selectively enabled or disabled by an administrator. Components within the virtualized network stack report packet drops and successful packet propagations to the packet monitoring application, which can filter the packets based on input parameters. Thus, a user can select at what level of granularity to filter packets within the virtualized network stack while being able to assess each packet's traversal through each component within the network stack. The packet monitoring application can also perform post-processing of on the filtered data packets to determine latency among components or sections of the virtualized network stack.Type: ApplicationFiled: May 31, 2019Publication date: October 8, 2020Inventors: Alexander MALYSH, Thomas Edward MOLENHOUSE, Omar CARDONA, Kamran REYPOUR, Gregory CUSANZA

Patent number: 10795717Abstract: Embodiments relate to hypervisors that provide hardware isolated virtualization environments (HIVEs) such as containers and virtual machines (VMs). A first HIVE includes a first virtual network interface card (NIC) and a second HIVE includes a second virtual NIC. Both virtual NICs are backed by the same physical NIC. The physical NIC has an Internet Protocol (IP) address. The virtual NICs are assigned the same IP address as the physical NIC. A networking stack of the hypervisor receives inbound packets addressed to the IP address. The networking stack steers the inbound packets to the virtual NICs according to tuples of the inbound packets. Packets emitted by the virtual NICs comprise the IP address, pass through the network stack, and are transmitted by the physical NIC with headers comprising the IP address.Type: GrantFiled: September 18, 2018Date of Patent: October 6, 2020Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Anirban Paul, Poornananda Gaddehosur Ramachandra, Gerardo Diaz-Cuellar, Osman Nuri Ertugay, Keith Edgar Horton, Omar Cardona, Nicholas David Wood, Shankar Seal, Dinesh Kumar Govindasamy

Patent number: 10666560Abstract: Various innovations for servicing of a virtual switch in a virtual networking layer are presented. The innovations include new architectures for a virtual networking layer and new operations performed when servicing a virtual switch. In some example implementations, during virtual switch servicing, interruption to actual network connectivity is minimal—below a timeout threshold that signifies failure of a network connection. Connections for a host, VMs, and physical network adapter can be maintained while the virtual switch is serviced. Although some interruption to actual network connectivity happens, apparent connectivity (for a VM) over a connection between the VM and the virtual switch can be maintained during the servicing of the virtual switch. Similarly, apparent connectivity (for a host) over a connection between the host and the virtual switch can be maintained during the servicing of the virtual switch.Type: GrantFiled: May 11, 2018Date of Patent: May 26, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Omar Cardona, Alexander Malysh, Sze K.
