    (Mahidol University, 2022) Watchara Satrabahndhu; Suratose Tritilanunt; Vasin Suttichaya; Tanasanee Phienthrakul
    Traffic characterization is the basis of network management, such as QoS. The traditional techniques, such as port base and deep packet inspection, are inadequate for encrypted traffic. Machine learning can utilize information hidden within... the traffic. This research proposed bi-direction flow None zero payload data extraction scheme BIF-NZP, bi-direction flow payload ratio feature (BIF-PR), and bi-direction flow payload ratio sequence (BIF-PRCS). ISCX VPN-NONVPN data set is used to evaluate

    A hybrid network transport protocol for multimedia traffic
    (Mahidol University. Mahidol University Library and Knowledge Center, 2014) Teeraphol Sukprapaipat; Noppadol Wanichworanant; Suratose Tritilanunt; Konglit Hunchangsith
    traffic when using these applications. This research presents a hybrid network transport protocol for real-time applications and multimedia traffic. The name of the hybrid protocol is the New User Datagram Protocol or NUDP. This protocol is based on UDP... and has been improved by using the retransmission method with modification to compensate for the packet loss rate. Furthermore, a function called "Sequencer" was added for re-ordering packets before sending to the application. This function can also reduce
