replacement files to every authorized client.” Column 2, lines 58 through 61.
We also make specific reference to the first paragraph of the Summary of the
Invention at column 4 of Aziz.
The requirements of address matching for communication purposes is
well known in the Internet communication art and is mentioned briefly at the
end of the first paragraph of the Background of the Invention at column 1 of
Aziz. It is indicated there that just as a person who sends a letter through a
normal postal service needs to know the recipient address, a client that
communications with a host via computer network also needs to know the
host network address. This requires a matching function and clearly any
time an address of a host computer would change on a network, the artisan
would well appreciate that this address information would have to be
updated in a clients’ memory files for bidirectional communication to occur.
Even in a secure communication environment, such as discussed at
column 3 and throughout Aziz, cryptographic methodology known in the art
requires a certain degree of matching of address information and other data
