Various embodiments describe multi-site cluster-based data intake and query systems, including cloud-based data intake and query systems. Using a hybrid search system that includes cloud-based data intake and query systems working in concert with so-called “on-premises” data intake and query systems can promote the scalability of search functionality. In addition, the hybrid search system can enable data isolation in a manner in which sensitive data is maintained “on premises” and information or data that is not sensitive can be moved to the cloud-based system. Further, the cloud-based system can enable efficient leveraging of data that may already exist in the cloud.

A method of restoring a failure in a network topology. A first node is provided that has a first access link connected to a first port group of a first customer and a first network link connected to a first active router. A second node has a first access link connected to the first port group of the first customer and a first network link connected to a second stand-by router. The first node has a second network link connected to the second node via a second network link of the second node. If the first access link of the first node or the first node itself fails, the second node switches to the active state. If the second network link of the first node fails, the second node switches to the active state. In this way the traffic will be forward to the first router and/or the second router.

The invention provides a multi-equipment batch firmware upgrading method for a mesh network device, which comprises the following steps that: a host generates a firmware compression packet with an identifier and sends the firmware compression packet to root node device of a mesh network; the root node device decompresses the firmware package, verifies the correctness of firmware, repackages and compresses the firmware, and pushes the firmware to the target node device in a multicast mode; the upgrade firmware supports breakpoint resume in the transmission process of the mesh network; and the target node device decompresses the firmware, performs CRC on the firmware identifier, and upgrades and restarts the firmware after passing the CRC. If the target node device is restarted abnormally, returning to the old version for starting. The target node device reports the version to the host after being started, and the host confirms whether upgrading succeeds or not. Through compression and breakpoint resuming, consumption of network and storage resources in the firmware transmission process is reduced, and the batch upgrading speed is increased; through firmware type inspection and a version fallback mechanism, device upgrading exception caused by mismatching of firmware and the to-be-upgraded device is prevented.

The invention discloses a method for generating a mobile node group in a wireless self-organizing network environment. The method is characterized in that each mobile node in a wireless self-organizing network configures a state of a node per se according to a finite-state mathematical model, and the method comprises the following steps that: (1) the mobile node broadcasts state information to a gateway at fixed time after being started until a reply message of a certain gateway in the wireless self-organizing network is received, the self-state is converted into a non-joined group state, and a message of the self-weight information is broadcast; (2) the mobile node positioned in the non-joined group state detects a joining invitation message of a peripheral cluster head node to join a mobile node group of the cluster head node, and the self-state is converted into a join group and is not a non-cluster head node state; (3) the mobile node positioned in the non-joined group state detects that a joinable mobile node group does not exist at the periphery, the mobile node converts the self-state into the cluster head node, a novel mobile node group is constructed, and the joining invitation message is broadcast. According to the method, the node can join the group or become a group in a short time after being started, the communication load of the gateway is greatly reduced, and the method has wide application prospects in a large-scale wireless self-organizing network environment.

A lash adjuster includes a body, a plunger which is inserted into the body and has a bottom wall with a valve hole and a peripheral wall having an oil passage hole and an inner periphery formed with a recessed groove, the plunger defining a high-pressure chamber between the bottom wall and the body, and a partitioning member inserted into the plunger. The partitioning member has an oil passage end located above the oil passage hole. The partitioning member has an oil-passage defining portion located opposite the recessed groove and defining an oil passage between itself and a groove face of the recessed groove. The partitioning member defines a low-pressure chamber inside. The low-pressure chamber reserves a hydraulic fluid flowing through the oil passage hole, the oil passage and the oil passage end. The low-pressure chamber causes the reserved hydraulic fluid to flow through the valve hole into the high-pressure chamber.

The invention discloses a cluster node communication method. The cluster node communication method comprises the following steps: a first master node obtains data of slave nodes in a first cluster and caches the data; the first master node is located in the first cluster; the first master node receives a call request of data of the slave nodes in the first cluster sent by a second master node, wherein the second master node is located in a second cluster; and the first master node caches to-be-called data requested by the second master node obtained from the cache and returns the to-be-called data to the second master node. According to the cluster node communication method, the master node caches the data of the slave nodes in the cluster, therefore the master nodes in other clusters can access the master node to obtain the data of the slave nodes in the cluster, therefore the direct communication between the slave nodes and the master nodes in other clusters can be avoided, and thus the reduction of system request response speed caused by the fault of the slave nodes can be avoided. The invention further discloses a cluster node communication system, which has the same beneficial effects.

A system and method limit transmission of wireless electromagnetic device radiation through the windows of a mobile platform outer envelope. A shielding layer is applied to the window and electrically grounded to the outer envelope. At least one transceiver hub is located within the mobile platform receiving and/or transmitting the electromagnetic device radiation. An off-board communication device wirelessly communicates with the transceiver hub. The shielding layer attenuates a portion of the radiation contacting the window. Only a communication path between the transceiver hub and the off-board communication device is therefore operable.
