Kehilangan dan kelewatan hujung ke hujung adalah kedua-dua metrik asas dalam penilaian prestasi rangkaian, dan ukuran yang tepat untuk metrik hujung ke hujung ini adalah salah satu kunci untuk mengekalkan aplikasi yang sensitif terhadap kelewatan/kerugian (cth, persidangan audio/video, IP telefon, atau telesurgeri) selesa pada rangkaian. Dalam kerja kami sebelum ini [1], kami mencadangkan kaedah pemantauan aliran selari yang boleh memberikan pengukuran aktif tepat kelewatan hujung ke hujung. Dalam kaedah ini, sampel kelewatan aliran sasaran meningkat dengan menggunakan hasil pemerhatian aliran lain yang berkongsi sumber/destinasi dengan aliran sasaran. Dalam kertas kerja ini, untuk meningkatkan ketepatan pengukuran kerugian, kami mencadangkan kaedah pengukuran kerugian dengan melanjutkan kaedah pengukuran kelewatan kami. Selain itu, kami menambah baik kaedah pengukuran kerugian supaya ia membolehkan untuk menggunakan sepenuhnya maklumat semua aliran termasuk aliran dengan sumber dan destinasi yang berbeza. Kami menilai kaedah yang dicadangkan melalui analisis teori dan simulasi. Penilaian menunjukkan bahawa ketepatan kaedah yang dicadangkan dibatasi oleh batas atas/bawah teori, dan disahkan bahawa ia mengurangkan ralat anggaran kadar kerugian sebanyak 57.5% secara purata.

Abstract: End-to-end loss and delay are both fundamental metrics in network performance evaluation, and accurate measurements for these end-to-end metrics are one of the keys to keeping delay/loss-sensitive applications (e.g., audio/video conferencing, IP telephony, or telesurgery) comfortable on networks. In our previous work [1], we proposed a parallel flow monitoring method that can provide accurate active measurements of end-to-end delay. In this method, delay samples of a target flow increase by utilizing the observation results of other flows sharing the source/destination with the target flow. In this paper, to improve accuracy of loss measurements, we propose a loss measurement method by extending our delay measurement method. Additionally, we improve the loss measurement method so that it enables to fully utilize information of all flows including flows with different source and destination. We evaluate the proposed method through theoretical and simulation analyses. The evaluations show that the accuracy of the proposed method is bounded by theoretical upper/lower bounds, and it is confirmed that it reduces the error of loss rate estimations by 57.5% on average.
