A method for allocating a device-specific resource from one or more databases is provided. The method includes receiving, at an interface, a coupling identifier including a pool identifier and a resource identifier, as part of a processing request from a requesting entity, the processing request including a request for the device-specific resource, wherein the coupling identifier associates the requesting entity with the device-specific resource based on the resource identifier, extracting, at the interface, the pool identifier from the coupling identifier, identifying, by the interface, the processing service in which the device-specific resource associated with the resource identifier is cached, based on the pool identifier, and transmitting, from the interface to the identified processing service, at least a part of the processing request to process the cached requested device-specific resource.

A network device may include a processor. The processor is configured to: receive a network address of a load balancer device from a management device; send a test request to the load balancer device based on the received network address; obtain a network address of a data collector device from the load balancer device; and perform a test with the data collector device. The data collector device is configured to: obtain a result of the test; and send the result to a data lake.

A method and corresponding set-up system arrangement are provided for actuating execution units. A communication node is further provided which is suitable for use in the method or in the system arrangement. Also provided is a computer program comprising control commands which implement the proposed method or operate the proposed system arrangement.

A method of assigning IP addresses to devices of a building control network includes receiving a selection of selected devices of a plurality of devices from a user interface. The selected devices are displayed in a predetermined order on a display. A proposed static IP address for a first device in the predetermined order of the selected devices is received from the user interface. A static IP address is sequentially assigned to each of the selected devices following the first device in accordance with the predetermined order, assuming the subnet mask has been confirmed as valid. The selected devices in the predetermined order along with the assigned static IP addresses for each of the selected devices are displayed on the display. The assigned static IP address for each of the selected devices are downloaded to the corresponding one of the selected devices.

A configuration of a cloud application exposed via a public IP address is duplicated with modifications to include a private IP address to expose the application internally. The original configuration is updated so that external network traffic sent to the application is redirected to and distributed across agents running on nodes of a cloud cluster by which web application firewalls (WAFs) are implemented. A set of agents for which the respective WAFs should inspect the redirected network traffic are selected based on cluster metrics, such as network and resource utilization metrics. The redirected network traffic targets a port allocated to the agents that is unique to the application, where ports are allocated on a per-application basis so each of the agents can support WAF protection for multiple applications. Network traffic which a WAF allows to pass is directed from the agent to the application via its private IP address.

According to certain embodiments, a system comprises a primary unit and a plurality of secondary units each having a unique unit number. The primary unit is configured to communicate a command to each secondary unit with instructions to reply during a time window. The primary unit is also configured to receive a reply communication indicating the secondary unit's unique unit number from at least one of the secondary units, and determine an address to assign to the replying secondary unit based at least in part on the received unique unit number.

A system and method are provided for a network device for use with a client device having a hostname and a MAC address. The network device contains a memory that has a second hostname and a second MAC address stored within the memory. The second MAC address corresponds to the second hostname. The memory also contains a processor configured to execute instructions stored on the memory to cause the network device to: receive, from the client device, the hostname and the MAC address; determine whether the MAC address is randomized; provide an instruction to the client device to inform a user of the client device that the client device hostname is registered when the hostname matches the second hostname and the MAC address is randomized.

A data processing system having an address resolution function for deriving MAC addresses. The set of MACs defined for the devices on the network encode physical position or logical identifier information of those devices. Therefore, each of these MACs is derivable using a mapping function that maps the physical position or logical identifier information supplied by an application to the MAC addresses of the devices on the network. When the protocol processing entity has to send data over the network, it can obtain the MAC address for the destination determined on the basis of the physical position or logical identifier supplied by the application. In this way, since the MACs are derivable on the basis of the physical positions or logical identifiers, the broadcasting of ARP request messages, which would otherwise be required when the protocol processing entity requires the MAC for the destination, may be avoided.

A network controller provides proactive notification of a wireless client device's address rotation to layer 2 (L2) and/or layer 3 (L3) devices. Traditional methods of device address discovery rely on broadcasting of address queries across a plurality of links until a path to a device having the queried address responds. As device address changes become more frequent in an effort to improve user privacy, traditional methods of address discovery impose a large burden on networks, reducing their performance and efficiency. By proactively propagating address changes to upstream devices, the need for broadcast oriented address discovery techniques is reduced, resulting in improved network performance.
