摘要： Various technologies related to multi-path communications in a data center environment are described herein. Network infrastructure devices communicate traffic flows amongst one another, wherein a traffic flow includes a plurality of data packets intended for a particular recipient computing device that are desirably transmitted and received in a certain sequence. Indications that data packets in the traffic flow have been received outside of the certain sequence are processed in a manner to prevent a network infrastructure device from retransmitting a particular data packet.

摘要： A cloud computing environment providing a network service for a client computing entity. The network service is not an application level service, but rather a service that operates at or below the network layer in the protocol stack. For instance, the network service might be a network endpoint service such as a network address service (such as DNS) or a dynamic network service (such as DHCP), or a network traffic service such as a firewall service or a secure tunneling service (such as VPN). The service might also provide a pipeline of network services for network level traffic to and from the client computing entity. The cloud environment uses policy to determine which of a plurality of communication channels to use when exchanging cloud service data for the network service.
摘要翻译：为客户端计算实体提供网络服务的云计算环境。网络服务不是应用级服务，而是在协议栈中的网络层之下或之下运行的服务。例如，网络服务可以是诸如网络地址服务（例如DNS）或动态网络服务（例如DHCP）的网络端点服务，或诸如防火墙服务或安全隧道服务的网络流量服务（如VPN）。该服务还可以为客户计算实体的网络流量提供网络服务流水线。云环境使用策略来确定在为网络服务交换云服务数据时使用多个通信信道中的哪一个。

摘要： A delivery controller for use in an enterprise environment that communicates with a cloud computing environment that is providing a service for the enterprise. As the cloud service processing progresses, some cloud service data is transferred from the cloud computing environment to the enterprise environment, and vice versa. The cloud service data may be exchanged over any one of a number of different types of communication channels. The delivery controller selects which communication channel to use to transfer specific data, depending on enterprise policy. Such policy might consider any business goals of the enterprise, and may be applied at the application level.

摘要： The provisioning of a host computing system by a controller located over a wide area network. The host computing system has power-on code that automatically executes upon powering up, and causes the host to notify the controller of the host address. In a first level of bootstrapping, the controller instructs the host to download a maintenance operating system. The host responds by downloading and installing a maintenance operating system, enabling further bootstrapping. The persistent memory may further have security data, such as a public key, that allows the host computing system to securely identify the source of the download instructions (and subsequent instructions) as originating from the controller. A second level of bootstrapping may accomplish the configuring of the host with a hypervisor and a host agent. A third level of bootstrapping may accomplish the provisioning of virtual machines on the host.

摘要： The present invention extends to methods, systems, and computer program products for offloading virtual machine flows to physical queues. A computer system executes one or more virtual machines, and programs a physical network device with one or more rules that manage network traffic for the virtual machines. The computer system also programs the network device to manage network traffic using the rules. In particular, the network device is programmed to determine availability of one or more physical queues at the network device that are usable for processing network flows for the virtual machines. The network device is also programmed to identify network flows for the virtual machines, including identifying characteristics of each network flow. The network device is also programmed to, based on the characteristics of the network flows and based on the rules, assign one or more of the network flows to at least one of the physical queues.
