Patent
Method and apparatus of packet switching
TL;DR: In this article, a packet including data for detecting a data error is formed for a data unit made up of a series of data packets sent to a packet mode terminal, and send to the packetmode terminal.
Patent
Packet exchange data transmission system
TL;DR: In this article, at least two packet exchangers are interconnected through an external transmission line to transmit a data packet, and each packet exchanger comprises a main controller for processing the data packet sent from a packet terminal, in a data link level and a packet level, and a connecting unit for sending the data packets sent from the main controller to the external transmission lines and sending data packet from the external transmissions to the main controllers.
Patent
Data encipherment transmission system
TL;DR: In this paper, an analyzer analyzes the character emerging frequency of the transmission data and produces and stores a compression table suited to the compression processing of data based on the result of analysis of the analyzer.
Patent
Error detecting system for exchange of packet
TL;DR: In this paper, the authors propose to increase the probability for error detection of data, by transmitting a packet added with an error detecting data of the data with a series of data packets addressed to a packet terminal as a unit.
Patent
Transmission system of packet switching data
TL;DR: In this article, the authors proposed a protocol to make extra-high speed transmission possible by performing processings of the data link level and the packet level of data packets from a packet terminal by a main control part and outputting them to an external transmission line after storing them temporarily.
