Abstract


Abstract. Novel Method to Detect Failed TCP Connection on Receiving Host Based on Packet Inter-arrival Timeout. TCP use retransmission timeout (RTO) as a standard mechanism to detect connection failure. Nevertheless, RTO can only be used by the sending host, and not by the receiving host. Until today there is no standardized mechanism for the receiving host to detect connection failure. Meanwhile a study on internet traffic shows that majority of internet traffic is unidirectional. This means the receiving host in majority of internet traffic does not have a standardized method to detect connection failure. This paper propose a novel method to detect failed TCP connection based on history of packet inter-arrival time. Simulation using NS2 shows the effectiveness of the proposed method.

Keywords: Failed TCP connection detection, receiving host, packet inter-arrival timeout

Abstrak. TCP menggunakan retransmission timeout (RTO) sebagai mekanisme standar untuk mendeteksi terputusnya koneksi. Namun RTO hanya dapat dimanfaatkan pihak pengirim data (sending host), sedangkan pihak penerima data (receiving host) tidak memiliki mekanisme untuk mendeteksi terputusnya koneksi. Sementara itu sebuah studi menunjukkan bahwa sebagian besar traffic internet bersifat satu arah. Ini berarti pihak penerima data pada sebagian besar traffic internet tidak memiliki metode yang terstandarisasi untuk mendeteksi terputusnya koneksi. Penelitian ini mengajukan sebuah metode baru bagi receiving host untuk mendeteksi terputusnya koneksi TCP berdasarkan jeda waktu antar paket data (packet inter-arrival timeout) yang diterima. Simulasi menggunakan NS2 menunjukkan efektivitas metode yang diajukan.

Kata Kunci: Deteksi terputusnya koneksi TCP, receiving host, packet inter-arrival timeout
