A method for IP [=Internet Protocol] communication between a mobile terminal and its correspondent node in a mobile radio network. The method comprises establishing an IP connection between the mobile terminal and its correspondent node. After detecting a period of inactivity in the IP connection, keep-alive messages are sent via the IP connection at predetermined intervals, which are varied. The method comprises monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection.

A selective sensor polling system for a voice activated data packet based computer network environment is provided. A system can receive audio signals detected by a microphone of a device. The system can parse the audio signal to identify trigger keyword and request. The system can select a template for an action data structure with a plurality of fields. The system can determine to poll a first sensor for data for the first field. The system can determine to obtain data in memory previously collected by the second sensor. The system can generate and transmit the action data structure with the data from the sensor and memory, and transmit the action data structure to a third party device.

A method for managing message transmission times from a first device to a destination of a second device. The devices have respective electrical load levels at a given time. The method includes receiving a request to change message transmission times, the request including the current electrical load level associated with the second device; and determining transmission times by taking into account the load levels of the first and/or second device.

An allocation apparatus configured to allocate a plurality of information processing devices to two or more management apparatuses that perform distributed management of the plurality of information processing devices, the allocation apparatus includes: an allocation unit configured to allocate an address range on a network, allocatable to a plurality of information processing devices, to the two or more management apparatuses; and an acquisition unit configured to obtain, from each of the two or more management apparatuses, management information indicating a state of the information processing device whose address belongs to a range allocated to the management apparatus, wherein the allocation unit dynamically performs allocation of the address range on the network based on the management information that has been obtained by the acquisition unit.

An extend ping protocol is described that allow connectivity tests to be performed for individual network interfaces of a target device without requiring network reachability between the testing device and the remote interface whose status is being queried. Moreover, the extend ping protocol supports a plurality of different probe types that allow an administrator to control how identification information within an extended ping echo request is resolved to the unreachable interfaces.

A method of optimizing network processing in a system comprising a physical host and a set of physical network interface controllers (PNICs) is provided. The physical host includes a forwarding element. The method includes determining that a set of conditions is satisfied to bypass the forwarding element for exchanging packets between a particular data compute node (DCN) and a particular PNIC. The set of conditions includes the particular DCN being the only DCN connected to the forwarding element and the particular PNIC being the only PNIC connected to the forwarding element. The method exchanges packets between the particular DCN and the particular PNIC bypassing the forwarding element. The method determines that at least one condition in said set of conditions is not satisfied. The method utilizes the forwarding element to exchange packets between the particular DCN and the particular PNIC.

A communication control system to obtain required reliability for an entire network is provided. The communication control system includes: a means for obtaining, based on a load status of a control device that controls nodes included in a network and receives a content of a control signal sent and received between the nodes as a status notification signal, a capability for processing the status notification signal; a means for determining, based on network status information related to communication on the network, area segments each including an arbitrarily number of the nodes; and a means for calculating, based on the capability, a sending interval of the status notification signal of the node for each of the area segments, and sending the sending interval to the node included in the corresponding area segment.
