You can access the documentation of all IKR libraries online.
We compared the results of the ns-2 and the IKR Simulation Library TCP implementations for standard scenarios and parameters. These results and some experiences during this evaluation are documented in a technical report compiled by guest researcher F. Querzola at the IKR.
During the development of VMSimInt we compared our implementation against the ns-3 in combination with the NSC. The results can be found in this publication.
