Hi everyone,
our Team has developed a minimal tcp/ip stack, my job is to test the
tcp/ip stack, can i get the test cases for testing the tcp/ip stack,
where can i get the necessary resources in internet. how should i
proceed, since iam new to protocol testing iam feeling some
difficulty, can any one can suggest some resources in internet.
Thanks in advance,
with regards,
Babu

The tool I am most familiar with is Maxwell, a product from InterWorking
Labs: http://www.iwl.com

Another tool I know only a little about is IxANVL, a product of IXIA:

You might also try using the (rather old) MIL-STD-1777 certification
tests as a guide to developing your own series (but it will require a
bunch of time to first define your own test suite and then develop and
debug programs to generate the needed traffic):

http://docs.mandragor.org/files/Museum/mil-std-tests/

The Maxwell product is a robustness tester. That is, its test cases will
exercise your stack's ability to handle unusual or invalid fields and
situations. The IxANVL is a conformance tester. It checks to see that
your stack does not operate contrary the RFCs. Rolling your own is best
suited if you have months (yes - months) of time and little or no money
to budget for off-the-shelf tests.

Conformance testing is nice but given a choice between interoperability
testing (i.e. tests that check that your stack can communicate properly
with machines running other stacks) and conformance testing, IMHO you
should test for interoperability. That is because there are holes in the
RFCs big enough to move small trucks, so your stack could be conformant
but still fail to interoperate in some cases. Testing a stack's ability
to interoperate with other stacks is the classic way to test stacks.

Robustness testing is always a very good idea once basic interoperability
has been established. Whereas interoperation tests and conformance tests
are for the most part "sunny day" testing, robustness tests like those in
Maxwell product provide the often missing "rainy day" scenarios. Or
attacks by malevolent entities. Also, the Maxwell product does include
some tests that can be categorized as conformance tests. And if their
test suite is insufficient it provides a programming API framework to
extend it.

Hope this s.
