I am thinking of something like the following: Sample Text =========== Protocol Foo encapsulates an IP datagram within the following: - a foo header - a UDP header - an outer IPv6 header Because the UDP checksum is set to zero, the following fields are unprotected: - foo header: field1 - foo header: field2 - UDP header: source port - UDP header: destination port - outer IPv6 header: source address - outer IPv6 header: destination address The consequence of corruption in field1 of the foo header is mumble. The consequence of corruption in field2 of the foo header is grumble, but only if some other condition is true. The consequence of corruption in any other field is, at worst, loss of the packet. Assume a tunnel with the following characteristics: - sustained data rate of 1 Gbps - Bit error rate of 10**-12 on each of 4 constituent links - average packet size equal to 1500 bytes The bullet list, below, provides an estimate of the frequency with which each of the above mentioned fields will be corrupted: - foo header: field1 (once per N seconds) - foo header: field2 (once per N seconds) - UDP header: source port (once per N seconds) - UDP header: destination port (once per N seconds) - outer IPv6 header: source address (once per N seconds) - outer IPv6 header: destination address (once per N seconds) ========================== End sample text Does this sound reasonable? -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
