摘要： The real-time aspects of keep-alive generation are removed from the dynamic routing protocol (DRP) application and are embedded within a Unix-based operating system, which is programmed by DRP. A keep-alive control provides the ability to create a keep-alive message and a timeout interval on a TCP socket. Each socket can have an independent keep-alive message and timeout interval. A keep-alive message is sent whenever the TCP socket sends no normal user output for a duration exceeding the timeout interval. A timeout interval is normally specified in seconds and a keep-alive message is user definable and must not exceed a predetermined length in bytes. System calls are used to set the timeout interval and keep-alive message independently. Both a timeout and a keep-alive message must be set before the timeout becomes active.

摘要： A system including multiple devices that each have a sensor and are each configured to communicate with other devices. The system further includes a controller configured to provide command information that specifies a mode of operation of the devices. In a first mode of operation, the devices transmit communication signals and a given device modifies a strength of its communication signal from an initial strength to a final strength based on communication signals it receives from one or more other devices. And in a second mode of operation, the devices transmit communication signals and the given device dynamically adjusts a strength of its communication signal based communication signals it receives from one or more other devices and on measurements performed by the sensor in the given device.

摘要： One embodiment of the present invention provides a system that facilitates in-cache reference counting in a cache memory. During operation, the system receives a command to update an old cache line with a new cache line. The system then determines if the new cache line is different than the old cache line. If so, the system determines if the old cache line contains any in-cache references. If so, for each such in-cache reference, the system decrements a reference counter in a cache line containing an object which is referenced by the in-cache reference. The system also determines if the new cache line contains any in-cache references. If so, for each such in-cache reference, the system increments a reference counter in a cache line containing an object which is referenced by the in-cache reference. Note that the reference counter in a cache line indicates a count of references in the cache that refer to an object contained in the cache line.
摘要翻译：本发明的一个实施例提供了一种有助于高速缓存存储器中的高速缓存引用计数的系统。在操作期间，系统接收到使用新的高速缓存行更新旧缓存行的命令。然后，系统确定新的高速缓存行是否与旧的高速缓存行不同。如果是这样，系统确定旧的高速缓存行是否包含任何缓存中的引用。如果是这样，对于每个这样的高速缓存引用，系统递减包含由缓存内引用引用的对象的高速缓存行中的引用计数器。该系统还确定新的高速缓存行是否包含任何缓存中的引用。如果是这样，对于每个这样的缓存引用，系统会增加包含由缓存内引用引用的对象的高速缓存行中的引用计数器。请注意，缓存行中的引用计数器指示缓存中引用包含在高速缓存行中的对象的引用计数。

摘要： One embodiment of the present invention provides a system that authorizes a sensitive database operation. During operation, the system receives a request to perform a sensitive database operation. Note that, a sensitive database operation is an operation which, in the hands of a malicious user, poses a serious security threat. Next, the system determines a multiparty authorization requirement for the sensitive database operation, wherein the multiparty authorization requirement specifies a set of approvals required for authorizing the sensitive database operation. The system then sends approval requests to one or more approving parties based on the multiparty authorization requirement. Next, the system receives approvals for authorizing the sensitive database operation. The system then determines whether the approvals satisfy the multiparty authorization requirement. Next, if the approvals satisfy the multiparty authorization requirement, the system authorizes the sensitive database operation, thereby allowing the database to perform the sensitive database operation.

摘要： A computer system that forwards data packets is described. During operation, the system receives a data packet on a first interface and classifies the data packet to determine a corresponding destination. This classification is based on dynamically configured classification rules that include multiple attributes corresponding to multiple layers in an Open System Interconnect (OSI) Reference model. Then, the system provides the data packet on a second interface corresponding to the destination.

摘要： One embodiment of the present invention provides a system that mitigates the effects of multiple vibration sources on a set of hard disk drives (HDDs) within a computer system. During operation, the system identifies a target HDD in the set of HDDs, wherein the performance of the target HDD is affected by mechanical vibrations. The system also identifies one or more primary vibration sources from the multiple vibration sources that affect the performance of the target HDD. Next, for each of the primary vibration sources, the system measures a first time-domain signal associated with the operation of the primary vibration source using a first vibration transducer associated with the primary vibration source. The system also measures a second time-domain signal associated with the target HDD using a second vibration transducer associated with the target HDD. Next, for each of the primary vibration sources, the system then computes a cross-power-spectral-density (CPSD) between the first and the second time-domain signals. The system then selectively mitigates the primary vibration sources based on the CPSDs between the primary vibration sources and the target HDD.

摘要： One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.

摘要： One embodiment of the present invention provides a system that provides heterogeneous resources for client systems. During operation, the system maintains a stateful resource database that tracks heterogeneous resources in a given environment. The system receives requests from client systems, and in response to the requests searches for a heterogeneous resource in the stateful resource database that matches the request. If the system finds an available heterogeneous resource that matches the request, it proceeds to submit the request to the resource. Maintaining and using the stateful resource database facilitates efficiently sharing scarce heterogeneous resources across a number of client systems.
