PDF-The surprising complexity of TCPIP checksums in the network stack Henning Brauer BS Web

The actual checksum math is easy and from a perfor mance standpoint so cheap that it can be con sidered free In the process of improving the use of hardware checksum of64258oading engines recalculating the IP checksum has been found to be essentialy. If error probability is 30 thats 1 error per 128 MB Some linklayer protocols provide error detection But UDPIP must work over many link layers Not all links on a path may have error detection Famous endtoend argument Functions that can only be done Chancen agiler www.akquinet.de Tielei.
