摘要： Methods and apparatus are provided for controlling communication between a virtualized network and non-virtualized entities using a virtualization gateway. A packet is sent by a virtual machine in the virtualized network to a non-virtualized entity. The packet is routed by the host of the virtual machine to a provider address of the virtualization gateway. The gateway translates the provider address of the gateway to a destination address of the non-virtualized entity and sends the packet to the non-virtualized entity. The non-virtualized entity may be a physical resource, such as a physical server or a storage device. The physical resource may be dedicated to one customer or may be shared among customers.

摘要： Methods and apparatus for congestion control in computer networks achieve high burst tolerance, low latency and high throughput with shallow-buffered switches. A method for controlling congestion includes transmitting a set of data packets on a network connection from a first computing device to a second computing device, identifying each data packet in the set of data packets that experienced congestion on the network connection, sending, by the second computing device to the first computing device, a sequence of bits that represents the number of data packets in the set of data packets that were identified as having experienced congestion, and adjusting a rate of transmitting data packets on the network connection based on the sequence of bits sent to the first computing device.

摘要： An enterprise namespace may be extended into a cloud of networked resources. A portion of the cloud may be dynamically partitioned, and the extension of the enterprise namespace established within the portion. Cloud resources thus remain as easily accessible to enterprise users as those which are physically located on the enterprise network. Thus, components such as applications, virtual machine instantiations, application states, server states, etc., may be easily migrated between the enterprise network and the cloud.

摘要： Described is a server monitoring technology that is scalable to large numbers of servers, e.g., in a datacenter. Agents on servers run queries to monitor data sources for that server, such as performance counters and other events. The agents monitor their resource usage and those of monitored events to stay within an administrator-specified resource budget (policy), e.g., by modifying the running queries and/or monitoring parameters. A controller receives results of the monitoring, analyzes the results, and takes action as needed with respect to server operation and monitoring. The controller may dynamically update an agent's queries, monitoring parameters and/or monitored data post-processing operations. The controller may issue alerts and reports, including alerts indicative of inter-server problems between two or more servers.

摘要： Exemplary methods, systems, and computer program products describe selecting a gateway based on health and performance information of a plurality of gateways. The techniques describe gateways advertising health and performance information, computing devices creating a table of this health and performance information, and selecting a gateway using the table. In response to changes in the health and performance information, the computing device may select a different gateway. The process allows network traffic load to be distributed across a plurality of gateways. This process further provides resilience by allowing a plurality of active gateways to substitute for a non-functioning gateway.

摘要： A method of enabling an electronic privately addressable source to be publicly addressable starts at a receiver where an electronic message is received. It is communicated from a sender with a private address outside a subnet of the receiver through a translator. The translator retrieves a lease to at least one of a public address or a port from a lease manager, translates the private address and the private port into a public address and a public port and communicates identifying data such as the public address and the public port to the receiver. If a response is communicated to the private sender, the response may be communicated to the private sender through the network. The public address and the public port on the message may be translated to the private address and the port of the private sender and the private address and the private port may be used to properly route the response to the private sender.
