    • ENDE (End-to-end Network Delay Emulator)
      • ENDE is a new network tool that emulates the end-to-end packet behavior including packet losses and delay in the Internet. It can be used as a testbed for testing new application layer protocols based on TCP or UDP
    • Internet Packet Behaviors Measurement Tools
      • The tools was designed for measuring the end-to-end Internet packet delay, loss, and duplication
