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 networking a plurality of servers together within a data center is disclosed. The method includes the step of addressing a data packet for delivery to a destination server by providing the destination server address as a flat address. The method further includes the steps of obtaining routing information required to route the packet to the destination server. This routing information may be obtained from a directory service servicing the plurality of servers. Once the routing information is obtained, the data packet may be routed to the destination server according to the flat address of the destination server and routing information obtained from the directory service.

摘要： A system for commoditizing data center networking is disclosed. The system includes an interconnection topology for a data center having a plurality of servers and a plurality of nodes of a network in the data center through which data packets may be routed. The system uses a routing scheme where the routing is oblivious to the traffic pattern between nodes in the network, and wherein the interconnection topology contains a plurality of paths between one or more servers. The multipath routing may be Valiant load balancing. It disaggregates the function of load balancing into a group of regular servers, with the result that load balancing server hardware can be distributed amongst racks in the data center leading to greater agility and less fragmentation. The architecture creates a huge, flexible switching domain, supporting any server/any service, full mesh agility, and unregimented server capacity at low cost.
摘要翻译：公开了一种用于商业化数据中心网络的系统。该系统包括用于具有数据中心的多个服务器和多个节点的数据中心的互连拓扑，通过该数据中心可以路由数据分组。系统使用路由方案，其中路由忽略网络中的节点之间的流量模式，并且其中互连拓扑在一个或多个服务器之间包含多个路径。多路径路由可能是Valiant负载平衡。它将负载平衡的功能分解为一组常规服务器，从而可以在数据中心的机架之间分配负载平衡服务器硬件，从而实现更高的灵活性和更少的分段。该架构创建了一个巨大的，灵活的交换域，以低成本支持任何服务器/任何服务，全面的网格敏捷性和未注册的服务器容量。

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.
摘要翻译：企业命名空间可以扩展到网络资源云。云的一部分可以被动态分区，并且在部分内建立企业名称空间的扩展。因此，云资源可以像物理上位于企业网络上那样容易地访问企业用户。因此，诸如应用，虚拟机实例化，应用状态，服务器状态等的组件可以容易地在企业网络和云之间迁移。

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.
