Dalam makalah ini kami menyiasat kebolehpercayaan sistem perlindungan kongsi jenis umum iaitu M untuk N (M:N) yang biasanya boleh digunakan pada pelbagai peranti rangkaian telekomunikasi. Kami memberi tumpuan kepada kebolehpercayaan yang dilihat oleh pengguna akhir salah satu daripadanya N unit. Kami menganggap bahawa mana-mana unit yang gagal diganti dengan serta-merta oleh salah satu daripada M unit (jika ada). Kami menerangkan keberkesanan sistem perlindungan sedemikian secara kuantitatif. Analisis matematik memberikan penyelesaian bentuk tertutup ketersediaan, algoritma pengkomputeran rekursif MTTFF (Masa Min kepada Kegagalan Pertama) dan MTTF (Masa Min untuk Kegagalan) yang dirasakan oleh pengguna akhir sewenang-wenangnya. Kami juga menunjukkan bahawa, di bawah keadaan tertentu, taburan kebarangkalian TTFF (Masa ke Kegagalan Pertama) boleh dianggarkan dengan taburan eksponen mudah. Analisis menyediakan maklumat berguna untuk analisis dan reka bentuk bukan sahaja peranti rangkaian telekomunikasi tetapi juga sistem perlindungan dikongsi umum lain yang tertakluk kepada perjanjian tahap perkhidmatan (SLA) yang melibatkan ukuran kebolehpercayaan yang dirasakan pengguna.

Abstract: In this paper we investigate the reliability of general type shared protection systems i.e. M for N (M:N) that can typically be applied to various telecommunication network devices. We focus on the reliability that is perceived by an end user of one of N units. We assume that any failed unit is instantly replaced by one of the M units (if available). We describe the effectiveness of such a protection system in a quantitative manner. The mathematical analysis gives the closed-form solution of the availability, the recursive computing algorithm of the MTTFF (Mean Time to First Failure) and the MTTF (Mean Time to Failure) perceived by an arbitrary end user. We also show that, under a certain condition, the probability distribution of TTFF (Time to First Failure) can be approximated by a simple exponential distribution. The analysis provides useful information for the analysis and the design of not only the telecommunication network devices but also other general shared protection systems that are subject to service level agreements (SLA) involving user-perceived reliability measures.
