Integer codes correcting single errors and double adjacent errors

The user datagram protocol is the most widely used protocol for streaming multimedia data over the Internet. Like other protocols at the network and transport layers, it uses the Internet Checksum (IC) to detect channel errors. The consequence of this is that each corrupted packet is dropped, which can degrade the quality of service perceived by a user. In this paper, the authors present a solution to this problem based on integer codes capable of correcting single and double adjacent errors. The presented codes are a generalization of the IC, which makes them easy to implement in software. The paper presents a class of integer codes that can significantly improve the transmission of multimedia data over the Internet. The proposed codes are a generalization of the Internet checksum and have the ability to correct single and double adjacent errors. image
