Research on Packet Loss Issues in Unidirectional Transmission

The unidirectional transmission technology is designed to protect the confidentiality of data on the high assurance network. It allows data to transmit only in one direction and prevents the use of acknowledgements or other connection-oriented mechanisms. This makes packet loss become a key issue in unidirectional transmission because of its influence on reliability and performance. In this paper, we build test platform of unidirectional transmission to research on packet loss issues, measure the loss data in unidirectional transmission, and analyze the correlation of the loss rate and the transmission rate, the data packet load. We use these empirical measurements to derive a Gilbert model for the characterization of Packet loss process in unidirectional transmission. The research results can help in reducing packet loss, improving the performance, and designing a good error correction coding scheme for unidirectional transmission.
