Latest Patents

Johansson's latest patents include groundbreaking methods for enhancing communication efficiency. One of his notable inventions is the "Ultra-low latency atomic multicast." This method is implemented by a computing device for atomic multicast support for a multicast group. It includes receiving a message order from a sequencer via remote write, defining a sequence for a plurality of messages from a multicast group. The method also involves receiving the plurality of messages from at least one sender in the multicast group via remote write and providing these messages to an application in the defined order, ensuring that all messages have been received.

Another significant patent is the "Low latency small message communication channel using remote write." This method is implemented by an electronic device for sending data on low latency communication. It includes remote writing a sequence number of a message to be sent next to a receiver, determining whether there is an open position in a receive buffer of the receiver using a local tracking mechanism, and writing data of the message to an area of an address space of a sending application that is mapped onto the receive buffer. This innovative approach enhances the efficiency of data transmission.
