摘要： An application programming interface (API) supporting server and key based networking is described. In an embodiment, the API receives either a key or a server address from a service running on a server in a direct-connect topology and returns data which identifies suitable next hops for transmission of a packet of data which has a destination of the received server address or of a server address which is encoded within the received key. In another embodiment, the key also encodes information specifying alternative server addresses for use in the event that the original server is unreachable. This information may also be used to define servers for replication of the key. A further embodiment describes a method of queuing packets for transmission against multiple links, where the packet is transmitted on the first available link and at this time is removed from the queues for the other links.

摘要： A system and method for discovering network topology by various switch training and probing methods. Segments are discovered by having computers enter a promiscuous mode and determining from packets sent to a selected computer which computers see which other computers in the network. From the segments, various switch interconnections are determined, by having different computers train switches as to a training address and seeing which computers receive probe packets sent to that training address from another computer. Various training and probing methods are described that locate intermediate segments, deep switches, switch interconnections, and edge and singleton cases. In one implementation, a master computer coordinates the other computers (and devices) in the network to send the training and probing packets, and report on received packets, in order to determine the network topology.

摘要： Supporting distributed key-based processes is described. In an embodiment, servers at a data center provide a key-based process for carrying out computationally expensive tasks and are connected using point to point connections in a geometric topology such as a torus. In an example, aggregation trees are built on top of the geometric topology of the data center, each aggregation tree being a sequence of servers in the data center that forms a tree structure. In an embodiment packets of data are sent from the leaves of the trees to the root and at each server along the tree the packets are aggregated using a combiner function of the key-based process. In an embodiment, if a server fails, the trees are dynamically recomputed and a recovery phase is triggered to resend any packets lost at the failed server. In some embodiments, packets are scheduled by inspecting the content of the packets.

摘要： Methods of querying a large number of endsystems are described in which metadata is replicated between endsystems. When a query is injected, an available endsystem receives a message relating to the query which identifies a range of endsystems for which that available endsystem is responsible. The available endsystem then generates completeness data for the range of endsystems based on data stored at the endsystem and this completeness data is transmitted to the sender of the message. The methods may be implemented using device-executable instructions which may be stored on device readable media.

摘要： Improved storage systems which use write off-loading are described. When a request to store some data in a particular storage location is received, if the particular storage location is unavailable, the data is stored in an alternative location. In an embodiment, the particular storage location may be unavailable because it is powered down or because it is overloaded. The data stored in the alternative location may be subsequently recovered and written to the particular storage location once it becomes available.
摘要翻译：描述了改进的使用写入卸载的存储系统。当接收到在特定存储位置存储一些数据的请求时，如果特定存储位置不可用，则将数据存储在替代位置。在一个实施例中，特定的存储位置可能是不可用的，因为它被断电或者由于其过载。存储在替代位置的数据可以随后被恢复并被写入特定的存储位置，一旦可用。

摘要： Described is a technology including an Ethernet layer 2 protocol by which a node of a computer network can discover information about other network computing elements, including discovering network topology information, and/or collecting diagnostic information. The protocol allows multiple responders to communicate data with a mapper node for topology discovery, with one or more enumerator nodes for quick enumeration, or with a controller node for network tests that collect diagnostic information. The responders process the received data to determine the type of service (quick discovery, topology discovery or network test) and the service type's related function, and take action based on these and possibly additional criteria in the data. Actions may include responding to the data, following received commands, collecting statistics, responding to queries, and so forth.
