Abstract
Checksums for internet protocol transmissions of certain transport layer messages are generated using IPv6 pseudo-headers for both IPv4 and IPv6 internet protocol transmissions. For IPv4 transmissions, IPv4 information is mapped into an IPv6 pseudo-header, and the checksum is computed using the IPv6 pseudo-header. Among other things, embodiments of the present invention allow checksums for both IPv4 and IPv6 internet protocol transmissions such transport layer messages to be computed using a common checksum computer.
