TInet6Checksum Class Reference

class TInet6Checksum : public TInet6Packet

This template class provides utilitlies to compute and check IPv6 Upper Layer Checksums These are not merged with the TInet6Packet class, because that class is intended (and is used) for all headers, not just upper layers.

The template parameter (Header class) must

have Checksum() method
have SetChecksum() method
the checkum in header must be aligned to 16 bit word
