Separating Noisy TCP/IP Session Flows Based on Natural Redundancy Decoding

ABSTRACT Aiming at the technical challenges of low latency and high reliability in the complex communication environment of the intelligent industrial network, and the trend of the current Internet of Things architecture is increasingly IP‐based, this paper proposes a fast and accurate IP packet forwarding method applied to the routing node, aiming at dealing with the header control packet error problem under high bit error conditions. This method breaks through the limitations of traditional retransmission mechanism and artificially adding redundant information, and only uses the natural redundant characteristics of the protocol itself to realize the correct separation of the session flow in high error environment. The test results on the public data set show that the proposed method can complete the separation of the session stream with a probability of not less than 99% at the bit error rate of by sacrificing part of the complexity, which provides a new idea and technical means for the fault‐tolerant receiving processing of the header five‐tuple field in complex communication environments.
