Abstract: The performance of multicast and/or broadcasting between virtual machines over a virtual network. A source hypervisor accesses a network message originated from a source virtual machine, and uses the network message to determine a virtual network address associated with destination virtual machines (after potentially resolving group virtual network addresses). Using each virtual network address, the hypervisor determines a physical network address of the corresponding hypervisor that supports the destination virtual machine, and also determines a unique identifier for the destination virtual machine. The source hypervisor may then dispatch the network message along with the unique identifier to the destination hypervisor over the physical network using the physical network address of the hypervisor. The destination hypervisor passes the network message to the destination virtual machine identified by the unique identifier.
Abstract translation: 通过虚拟网络在虚拟机之间进行组播和/或广播的性能。 源虚拟机管理程序访问源虚拟机的网络消息，并使用网络消息来确定与目标虚拟机相关联的虚拟网络地址（潜在解决组虚拟网络地址之后）。 使用每个虚拟网络地址，管理程序确定支持目标虚拟机的相应管理程序的物理网络地址，并且还确定目的地虚拟机的唯一标识符。 然后，源虚拟机管理程序可以使用管理程序的物理网络地址将网络消息与唯一标识符一起通过物理网络发送到目的虚拟机管理程序。 目标管理程序将网络消息传递到由唯一标识符标识的目标虚拟机。

Abstract: Individual role instance reachability and load balancing are simultaneously provided for role instances of an application running in a hosting environment. Instance endpoints may be assigned to each role instance. Each instance endpoint may comprise a combination of an IP address, a transport protocol, and a unique port number. Additionally, a load balanced endpoint may be assigned to the group of role instances. The load balanced endpoint may comprise a combination of an IP address, transport protocol, and another unique port number. When application messages are issued to the data center, the messages are routed in accordance with endpoints used by the messages. For an instance endpoint, the message is routed to a role instance corresponding with the instance endpoint without load balancing. For the load balanced endpoint, the message is routed to any one of the role instances using load balancing.

Abstract: Computerized methods, systems, and computer-readable media for promoting cooperation between a first and second virtual network overlay ("overlay") are provided. The first overlay is governed by a first authority domain and includes members assigned virtual IP addresses from a first address range. The second overlay is governed by a second authority domain, which is associated with a second federation mechanism, for negotiating on behalf of the second overlay. The second federation mechanism is capable of negotiating with, or soliciting delegation of authority from, a first federation mechanism that is associated with the first authority domain. When negotiations are successful or authority is delegated, the second federation mechanism establishes a communication link between the second overlay and the first overlay or joins a member of the second overlay to the first overlay. Joining involves allocating a guest IP address from the first address range to the member.

Abstract: Cloud computing platforms having computer-readable media that perform methods to shape virtual machine communication traffic. The cloud computing platform includes virtual machines and a controller. The controller limits the traffic associated with the virtual machines to enable the virtual machines to achieve desired communication rates, especially when a network servicing the virtual machines is congested. The controller may drop communication messages associated with the virtual machines based on a drop probability evaluated for the virtual machines.

Abstract: Computerized methods, systems, and computer-storage media for establishing and managing a transmission control protocol (TCP)-based tunnel (“tunnel”) are provided. The tunnel spans between a data center and a private enterprise network and connects endpoints, of a service application, that reside in each location. During communication, the endpoints transmit data packets over one or more channels (e.g., higher-level channel and lower-level channel) that comprise the tunnel. Each of the channels supports reliability mechanisms (e.g., congestion-control mechanism and loss-recovery mechanism) integrally running thereon, for ensuring complete data-packet delivery. To prevent unwarranted performance degradation caused by duplicative efforts of reliability mechanisms, a fabric controller is employed to selectively disable one or more of the reliability mechanisms individually. The selective disablement of the reliability mechanisms is invoked by predefined criteria, such as instructions from a service model or detected identity of a source/destination endpoint, and is invoked on a per network connection basis.

Abstract: A computer may be capable of communicating with devices via network through multiple interfaces. When a new connection is to be established, the computer may select an interface to use for the connection. In some embodiments, the interface may be selected based on historical connection information representing the performance of previous network connections that the computer has established through the interfaces.

Abstract: Computerized methods, systems, and computer-readable media are provided for establishing and managing a virtual network (V-net) and virtual machine (VM) switches that enable protected and isolated interconnections between members of the V-net. The V-net members include an originating network adapter that generates data packets addressed to a destination network adapter. Upon detecting data-packet generation, a source-side VM switch accesses a forwarding table associated with the V-net, ascertains a destination-side, VM-switch locator that corresponds to an identifier of the destination network adapter, and modifies the data packets to include the identifier. The forwarding table represents a mapping between the members of the V-net and VM switches located on respective nodes within the data center. In operation, the mapping enforces communication policies that govern data-packet traffic. Upon receiving the data packets, the destination-side VM switch restores the data packets and forwards them to the destination network adapter.
