Abstract
Forward error correction techniques are applied and imbedded in the designated spaces of all the Internet Transmission Protocols in the Application Layer, the Transport Layer, the Network Layer, and the Link Layer. Encoding methods are performed at the transmitting end and corresponding decoding algorithms are performed at the receiving end. Error correcting codes are used at the receiving end to check and correct the received transmissions. This invention achieves significant better performance and quality of service (QoS) in terms of capacity amelioration, efficiency enhancement, reliability improvement, message delay reduction, bandwidth conservation, faster signaling, and the prevention of traffic congestion. The results are obtained effortlessly, simply, and simultaneously. All the above attributes are accomplished without adding complexity for each improvement. The methods to accomplish such features is through specific forward error corrections by means of replacement Checksums, CRCs, and ARQs for all the Internet Transmission Protocols without a single digit change from the established International Standards. By the unique method of converting all blockless convolutional c…
