In a distributed sensor network, one or more devices, for example, forming a collaborative group, are associated with a physical phenomenon based on geographical proximity. The sensor network is capable of detecting new phenomena and changing the membership of the collaborative group as the phenomenon changes. Sensors not associated with a detected phenomenon are available to detect new phenomenon, and one group may exist per phenomenon. Upon detection of a phenomenon, a group of nodes is formed and a leader node is elected. As the phenomenon changes over time, new devices come into proximity of the phenomenon and are prevented from forming independent groups associated with the phenomenon. This accomplished in a decentralized way with communication restricted to local neighbors. In a tracking sensor network using a relatively small number of sensors, the sensors are active and maintain a coherent belief associating their measurements with a single common vehicle.

A system is provided to optimize multiple boiler plant systems having mixed condensing and non-condensing boiler groups. The system advantageously employs the independent groups of boilers depending on preset conditions under control of a system control unit. The preset conditions are checked against operating conditions of the boiler plant, and a system control unit controls which of the groups of boilers is the lead and which is secondary. In some instances, both groups of boilers may be utilized under heavy load. Further, effective switching between groups and within groups is also provided to minimize unnecessary repetitive boiler operation.

The invention relates to a five-particle Brown state-based quantum grouping secret information comparison method. By the method, the secret information of two groups of users can be compared simultaneously by utilizing the Brown state, and the secret information is not leaked to a third party who performs comparison. The third party TP is semi-loyal, and can execute comparison honestly and record the comparison result; meanwhile, the third party TP may try to steal information from the record. The actual requirement is met and universality is achieved. A user can execute interception detection and loyalty detection on the TP after the TP distributes photons. The information is encoded by a participant, so that an eavesdropper, even if the TP, cannot know the respective secret information. Compared with the existing quantum secret comparison method, the method has the advantages that the secret information of the two independent groups of users can be compared simultaneously through one group of Brown state, and the secret information is not leaked to the third party who performs comparison.

A cloud manager is utilized in the patching of physical machines and virtual machines that are used within an online service, such as an online content management service. The cloud manager assists in the scheduling of the application of software patches to the machines (physical and virtual) within the network such that the availability of the online service is maintained while machines are being patched. The machines to be patched are partitioned into groups that are patched at different times. Generally, the groups are partitioned into a highly available independent groups of machines such that one or more of the groups that are not currently being patched continue to provide the service(s) of the group that is being patched. The machines (physical and virtual) within each of the groups may be patched in parallel.

A method and apparatus for buffering data units in a communication switch that allows for configurable monitoring of the buffer contents is presented. Such an apparatus includes a context table that stores a plurality of independent group identifiers for each connection. Although the group identifiers may include a partition group identifier and a loss group identifier that is dependent on the partition group identifier, additional group identifiers are included in the context table for each connection that are independent of other group identifiers in the context table. Such a context table may be dynamically reconfigured in order to group connections for buffer monitoring operations related to congestion detection, traffic shaping, and data admission with respect to buffering. When a data unit is received corresponding to a particular connection, the context table is referenced to retrieve the set of group identifiers corresponding to that connection. As a cell is stored in the buffer, count values corresponding to at least some of the group identifiers included in the set of group identifiers for that connection are incremented. Similarly, when data is dequeued from the buffer for forwarding, the set of group identifiers for that particular data unit is determined and the counters corresponding to at least some of those groups are decremented. As such, the count value corresponding to each of the groups can be referenced to determine the number of data units corresponding to that group that are currently stored within the buffer.
