摘要： A system and method supporting efficient, scalable stateful switchover of transport layer connections in a telecommunications network element. One method involves receiving, at a network element comprising an active transport protocol process coupled to a standby protocol process, a request to configure a first transport layer connection maintained at the active transport protocol process for stateful switchover; receiving an event associated with the first transport layer connection; creating a message containing replicated event information based on the received event; sending the message to the standby transport protocol process; and processing the message at the standby transport protocol process, wherein the standby transport protocol process replicates state information for the first connection.

摘要： A system and method for enabling a second database instance to more quickly process a request to execute a database statement that has previously been executed by a first database instance is described. In one embodiment, the method involves sending the database statement from the first database instance to the second database instance, and generating by the second database instance one or more structures needed to prepare the statement for execution, such as a parse tree and an execution plan for the statement. If at some point in the future, the second database instance receives a request to execute the same statement, the above structures can be used for execution, thereby eliminating the need for one or more potentially time-consuming operations, such as generation of a parse tree or execution plan for the statement.

摘要： Techniques and systems for automatically configuring devices to interact with “legacy” wireless access points (“WAPs”) are disclosed. According to one technique, a user programs a WPS-enabled WAP with the configuration information of a “legacy” WAP. This makes the WPS-enabled WAP “aware” of the “legacy” WAP. When any other user brings his device within discovery range of the WPS-enabled WAP, the WPS-enabled WAP sends, to that device, a list of the WAPs of which the WPS-enabled WAP is aware. The device's user selects one of the WAPs (e.g., a “legacy” WAP) from the list. The WPS-enabled WAP receives the user's selection and sends, to the device, the configuration information for the selected WAP. The user's device configures itself, using the configuration information, to interact with the selected WAP. Thereafter, the user's device can access a network through the selected WAP, even if the selected WAP is a “legacy” WAP.

摘要： Techniques are described to increase the diversity or focus of image search results. A user submits an original query to search for images. A server generates a first results set by executing the original query using metadata associated with each image. The server selects, from the first results set, a specified number of results ranked highest and generates a list of terms from the metadata of each of the results selected. The terms may be only the tags of the results. The server generates an updated query using terms in the list that may be weighted based on the frequency of the term in the list or include only a specified number of the highest occurring terms in the list. The server generates a second results set by executing the updated query using metadata associated with each image. The second results set is then stored and displayed to the user.

摘要： Techniques are described herein for synchronizing cluster time. According to one technique, a master node is appointed in a cluster. Other “slave” nodes periodically synchronize their clocks with the master node. To synchronize its clock with the master node, a slave node sends a timestamped message to the master node, which also timestamps the message and sends the message back to the slave node, which then timestamps the message again. Based on the timestamps, the slave node is able to determine the difference between the master node's clock's time and slave node's clock's time, compensating for the message travel time between master node and slave node. Depending on various circumstances, and based on the determined difference, the slave node adjusts its clock so that the time indicated by the slave node's clock at least begins to approach more closely the time indicated by the master node's clock.
摘要翻译：这里描述了用于同步集群时间的技术。根据一种技术，在簇中指定主节点。其他“从”节点周期性地将其时钟与主节点同步。为了将其时钟与主节点同步，从节点向主节点发送时间戳消息，主节点还对消息进行时间戳，并将消息发送回从节点，从节点再次对消息进行时间戳。基于时间戳，从节点能够确定主节点的时钟和从节点的时钟时间之间的差异，从而补偿主节点和从节点之间的消息传播时间。根据各种情况，并且根据所确定的差异，从节点调整其时钟，使得从节点的时钟指示的时间至少开始接近主节点时钟指示的时间。

摘要： A method is disclosed for enabling stateless server-based pre-shared secrets. Based on a local key that is not known to a client, a server encrypts the client's state information. The client's state information may include, for example, the client's authentication credentials, the client's authorization characteristics, and a shared secret key that the client uses to derive session keys. By any of a variety of mechanisms, the encrypted client state information is provided to the client. The server may free memory that stored the client's state information. When the server needs the client's state information, the client sends, to the server, the encrypted state information that the client stored. The server decrypts the client state information using the local key. Because each client stores that client's own state information in encrypted form, the server does not need to store any client's state information permanently.
摘要翻译：公开了一种实现无状态的基于服务器的预共享机密的方法。基于客户端不知道的本地密钥，服务器加密客户端的状态信息。客户端的状态信息可以包括例如客户端的认证凭证，客户端的授权特征以及客户端用于导出会话密钥的共享秘密密钥。通过各种机制中的任一种，加密的客户端状态信息被提供给客户端。服务器可以释放存储客户端状态信息的内存。当服务器需要客户端的状态信息时，客户端向服务器发送客户端存储的加密状态信息。服务器使用本地密钥解密客户端状态信息。因为每个客户端都以加密形式存储客户端自己的状态信息，服务器不需要永久存储任何客户端的状态信息。

摘要： Constraints that restrict how corresponding identifiable groups of files are stored in a database, are enforced on corresponding file data. In response to a query on any data from an identifiable group of files, the effect of the constraint on how the corresponding data is stored is determined. The original query is rewritten, based on the effect of the constraint, so that the rewritten query is directed to a particular subset of the data stored in the database. Consequently, the search space is restricted to an identifiable subset of the database and execution of the rewritten query is more efficient than execution of the original query.
