摘要： Described is a technology by which a relative load of network traffic handling is determined between servers of a cluster, based upon time values that correspond to the time taken by each server to handle a packet. Load may then be transferred between the servers based upon the relative load, for example by having a less-loaded server take some of the responsibility for processing incoming traffic from a more-loaded server. For example, the processing time of a server may be determined by when a receiving server receives a request packet, and when that server sends a return packet. A round trip time for a request and return communication may also be established. A logical tree of nodes representing the servers may be constructed to select pairs of servers for balancing with one another, with the selection algorithm operating recursively, in parallel, and/or repeatedly, until the cluster is balanced.

摘要： Techniques for employing a decentralized sleep management service are described herein. In some instances, each computing device of a group of computing devices periodically shares information about itself with each other computing device of the group. With this information, each computing device within the group that is awake and capable of managing other devices selects a subset of devices to probe. The devices then probe this subset to determine whether the probed devices are asleep. In response to identifying a sleeping device, the probing device takes over management of the sleeping device. Managing the sleeping device involves informing other devices of the group that the sleeping device is being managed, in addition to monitoring requests for services on the sleeping device. In response to receiving a valid request for a service hosted by the sleeping device, the managing device awakens the sleeping device and ceases managing the now-woken device.

摘要： Described is a technology in a network load balancing system (node cluster), by which client affinity is preserved across cluster configuration changes, including for new connections from a previous client. Each node maintains a list of the clients that are to remain (have affinity, or “stickiness”) with that node, including following bucket redistribution resulting from convergence. Each affinity list is communicated during convergence so that other nodes may build an exception list or lists. Via a node's exception list, the node that owns a bucket corresponding to a client knows of the affinity with another node and thus drops any packets from that client. Affinity may expire, whereby the node having affinity with that client releases it and notifies the node owning the bucket for that client that the client is no longer to be treated as an exception.
摘要翻译：描述了网络负载平衡系统（节点集群）中的技术，通过该技术，可以跨集群配置更改保留客户端关联，包括来自以前客户端的新连接。每个节点维护与该节点保持（具有亲和性或“粘性”）的客户端的列表，包括从收敛引起的后续重新分配。每个关联列表在收敛时进行通信，以便其他节点可以构建一个例外列表或列表。通过节点的异常列表，拥有与客户端相对应的桶的节点知道与另一个节点的亲和性，从而丢弃该客户端的任何数据包。亲和度可能会过期，由此与该客户端具有亲和力的节点将释放它，并通知拥有该客户端的存储区的客户端不再将该客户端视为异常。

摘要： Techniques for testing software applications in stack-based computing environments are discussed. A tested application is executed at predetermined logical positions in a stack, such as at a layer of the OSI reference model. An expected result of an operation performed by the application is identified. A first set of computer-executable instructions is installed at a first position logically above the tested application, and a second set of computer-executable instructions is installed at a second position logically below the tested application. One or both sets of instructions simulate inputs to the application. The application is executed based on the simulated inputs, and one or both sets of instructions are used to compare outputs from the application with the expected result. Various, virtually unlimited tests can be performed on the software application without the use of extensive test infrastructure.

摘要： Diagnosing problems in distributed systems. In one aspect, a model of a distributed system defines trace statements are generated by various nodes of the system and placed in log files. The log files are sent to an automatic validator that attempts to reconcile the trace statements against the model. Results of the attempt are indicated. In another aspect, trace statements are received by a multiplexer that creates an ordering via sequence numbers. The ordering is forwarded to an automatic validator to determine whether the trace statements indicate correct behavior.

摘要： Aspects of the subject matter described herein relate to client affinity in distributed load balancing systems. In aspects, a request from a requester is sent to each server of a cluster. Each server determines whether it has affinity to the requester. If so, the server responds to the request. Otherwise, if the request would normally be load balanced to the server, the server queries the other servers in the cluster to determine whether any of them have affinity to the requester. If one of them does, the server drops the request and allows the other server to respond to the request; otherwise, the server responds to the request.
