摘要： Systems, methods, and computer storage media for upgrading a domain in a distributed computing environment are provided. Upgrading of the domain includes preparing for the upgrade, upgrading, and finalizing the upgrade. The preparation of the domain includes ensuring predefined quantities of role instances are available in domains other than the upgrade domain. The preparation also includes ensuring that a predefined number of extent replicas are available in domains other than the upgrade domain. The preparation may also include checkpointing partitions within the upgrade domain to facilitate faster loading once transferred to a domain other than the upgrade domain. The finalization may include allowing nodes within the upgrade domain to resume functionality that was suspended during the upgrade.

摘要： Systems, methods, and computer storage media for storing and retrieving data from a data store in a distributed computing environment are provided. An embodiment includes receiving data at a data store comprising a sequential journal store, RAM, and a non-sequential target store. When RAM utilization is below a threshold, received data is stored to the RAM as a write cache for the target store and the journal store. But, when the utilization is above the threshold, the data is stored to the journal store without write-caching to the RAM for the target store. When the RAM utilization falls below a threshold, data committed to the journal store, but not write-cached to the RAM for the target store, is later read from the journal store and write-cached to the RAM for a target store.

摘要： A method for setting timers is disclosed in which an array is maintained, each element of which represents a period of time. Events which are to occur within the time period associated with the array element are linked to the array element. The events associated with each array element are executed at a pre-determined time interval. A pointer pointing to the current time period being processed wraps around to the beginning of the array when the end of the array is reached.

摘要： A network protocol and associated methods for optimizing use of available bandwidth across a network under varying traffic conditions. The protocol and methods allow the available bandwidth for a link connecting two computers to be determined on an ongoing basis. A method for measuring a clock bias between two computers linked in communication is also presented, along with methods for determining link saturation and dropped messages. The message send rate of the link can be continually tuned based on the measured bandwidth, link saturation condition, number of backlogged messages and/or detection of dropped messages. The protocol and methods preferably are implemented as part of an application program interface. The protocol resides at the application layer, and can be used for various network protocol suites, including TCP/IP and IPX/SPX.

摘要： Systems, methods, and computer storage media for load balancing at a client device in a distributed computing environment based on a dynamic validity duration and utilization metrics of one or more data stores are provided. The client device selects a data store from a plurality of data stores that each maintains a copy of a datum. The selection of data stores by a client is based on utilization metrics of the data stores. The utilization metrics are stored at the client. A data store determines if a request for a particular datum may be fulfilled within a validity period associated with a request from the client. The validity period is dynamically changed by the client across multiple requests to aid in the load balancing process. Additionally, a gossip protocol may be used to propagate utilization metrics of a plurality of data stores across the system.

摘要： A networking protocol that supports the sending of reliable and non-reliable data in a common sliding window. Data to be transmitted according to the protocol is packaged into packets, where each packet has a header. Each packet carries a sequence number in the header, where the sequence numbers are successively assigned to each outgoing packet. As the packets are received, the recipient of the packets keeps track of the sequence numbers of received packets to determine whether any packets are missing and selectively acknowledges those packets that have been received. The selective acknowledgment is performed using a mask, where each bit in the mask indicates the presence or absence of a packet as an offset from a reference value. Based on the mask, the sender re-sends non-received reliable packets, and creates a second mask which indicates non-reliable non-received packets that will not be re-sent.

摘要： A method and system for adding a secured network server to an existing network for access by a client thereof, wherein the added server does not possess a database of authentication credentials. The client is first authenticated for access to the added server by passing authentication requests received from the client to an authenticating agent having a database of authentication credentials, which may include information from a bindery comprising users, groups and passwords. The responses from the authenticating agent are then evaluated, and if the response indicates validity, the client is the granted access to the added server. Database services are provided to the authenticated client by first evaluating database requests received from the client. Requests seeking information maintained by the authenticating agent are handled by passing the requests to the authenticating agent and using its response to reply to the client.
