Embodiments relate to methods, systems, and computer program products for path management in a processing system. In a method, in response to receiving a request for adding a target controlling unit into a processing system, a plurality of network nodes in the processing system are divided into a group of subnets based on a topology of the plurality of network nodes, the plurality of network nodes being connected to at least one controlling unit in the processing system. A workload estimation is determined, the workload estimation representing a workload to be caused by the target controlling unit to the processing system. A target subnet is selected from the group of subnets for connecting the target controlling unit into the processing system based on the workload estimation. With these embodiments, the target subnet may be selected in an automatic way such that the performance of the processing system may be increased.

Path management

Methods, systems, and computer program products for communicating with a device on nearby wireless network are provided. Aspects include receiving, by a user device, a beacon frame from an access point of a wireless network. Aspects also include obtaining, by the user device from the beacon frame, direct link information for the wireless network, wherein the direct link information includes connection information for a guest network associated with the wireless network. Aspects further include receiving, by the user device from a user, a message intended for the device on the wireless network and connecting, by the user device, to a guest network. Aspects also include transmitting, by the user device, the message to the device.

Communication with a device on nearby wireless network

An embodiment for cancelling echo in online conference systems is provided. According to some embodiments of the present disclosure, the computer-implemented method comprises, in response to an update of devices of participants in an online conference, dividing, by one or more processors, the devices in an online conference into a plurality of groups, wherein the devices located in a same physical location are divided into a same group. The method also comprises, in response to an update of the devices in an online conference, selecting at least one speaker of the devices in each of the plurality of groups as a representative speaker for each of the plurality of groups. The method further comprises forwarding audio data received from microphones of the devices in one of the plurality of groups to the respective representative speaker of other groups of the plurality of groups.

Echo cancellation in online conference systems

The present invention provides a computer implemented method, system, and computer program product for monitoring a ticket, the method including receiving credentials by a processing unit from a device via manual presentation of the device to a manual sensor logically coupled to the processing unit, generating a ticket identifier (ID) based on the credentials, transmitting the ticket ID from the processing unit to the device, establishing a wireless connection between the device and the processing unit, checking the wireless connection before each occurrence of an event, checking the wireless connection after each occurrence of the event, and updating a status of a ticket in light of the checking. In an exemplary embodiment, a ticket system includes a processing unit, a manual sensor, a wireless sensor, and a device, where the processing unit transmits the ticket ID, and where the processing unit verifies continued connection at key events.
