NAME

        CL_RFC1035_2_3_2_order_octets - Order of transmission of octets and bits

VERIFICATION POINTS

        Verify that a NUT transmits correct order of transmission of octets and bits

The order of transmission of the header and data is resolved to the octet level.
The order of transmission of octets is the normal order in which they are read in English.
Whenever an octet represents a numeric quantity, the left most bit in
the diagram is the high order or most significant bit.
Similarly, whenever a multi-octet field represents a numeric quantity
the left most bit of the whole field is the most significant bit.
When a multi-octet quantity is transmitted the most significant octet is
transmitted first.

TARGET

        Client

JUDGMENT

        1. Standard query must be based on above Verification Points.
                *Order of transmission of octets is the normal in which they are read in English.
                        *Check order of transmission of octets in DNS header.
                *The left most bit in the octets is most significant bit.
                        *Check numeric quantity of OPCODE, Z fields in DNS header.
                *The left most bit in the multi-octets field is most significant bit.
                        *Check numeric quantity of QDCOUNT, ANCOUNT, NSCOUNT, ARCOUNT fields in DNS header.

TERMINATION

        If NUT has cache function, clear the cache.
