We implemented an XTP simulation module running with VINT/NS simulation engine, and an application-level XTP software in Windows environment. We performed analysis and measurement between real implementations. Although the application-level XTP has more implementation overheads than TCP in system kernel, we still have found some inbred advantages in XTP under certain conditions.
