One embodiment of the present invention sets forth a technique for processing packets transmitted within a network in accordance with a network protocol. The technique includes a network device in a mesh network receiving a type-length-value (TLV) element, determining, based on a type field of the TLV element, an expected length of a value field of the TLV element, and processing the value field up to the expected length.

A system that synchronizes waveforms received over a network from one or more devices, such as medical devices. Because of network delays or losses, waveforms can arrive at varying rates and times. Precise post-synchronization of the received data, to within a few milliseconds, is needed for accurate analysis. Applications include automatic classification of waveforms, such as detection of myocardial infraction from heart monitor waveforms. Synchronization uses sequence numbers assigned by each device, but must also account for sequence number wraparounds. Waveforms may also be synchronized across devices, by calculating the bias between within-device synchronized times and a common time source or common disturbance. Waveform data may also be stored data in a database or data warehouse; embodiments may index the data using a key with a date-time prefix and a hash code suffix, to support distributed indexing while reducing the chance of hash collisions to a very small probability.

A proxy server (700) receives, from a sending device, a packet intended for a receiving device (600). The proxy sewer (700) sends, to the receiving device (600), a promise frame (300) indicating that the proxy server (700) will deliver the packet to the receiving device (600) later. The receiving device (600) receives the promise frame (300) from the proxy server (700), and sends an acknowledgement of the packet to the sending device via the proxy sewer (700). The proxy server (700) forwards the acknowledgement of the packet from the receiving device (600) to the sending device, and delivers the packet to the receiving device (600) after having forwarded the acknowledgement to the sending device. The receiving device (600) receives the packet from the proxy server (700) after having sent the acknowledgement of the packet to the sending device via the proxy server (700).

A country estimation device includes processing circuitry configured to collect path information for each IP address, extract attribute information assigned to the collected path information, and estimate a country where the IP address is located by referring to attribute information indicating a country at a link destination of a path of the path information among the extracted attribute information.

This disclosure generally relate to a method and system for network policy simulation in a distributed computing system. The present technology relates techniques that enable simulation of a new network policy with regard to its effects on the network data flow. By enabling a simulation data flow that is parallel and independent from the regular data flow, the present technology can provide optimized network security management with improved efficiency.

A method in which a monitoring unit allocated to a communication device checks, based on a name resolution protocol, whether a second communication network address allocated to the first communication device becomes valid in order to set up an uninterrupted communication connection to the communication device that is allocated to an industrial automation system, where in cases of an allocation of a new valid communication network address and an existing communication connection, the monitoring unit initiates a set-up of an additional communication connection using the new communication network address.
