摘要

本文报告了IST-project NOBEL中定义通用可用性模型并收集几种网络设备类型的通用可用性数字的倡议，独立于供应商特定的产品信息。该模型包括光层设备以及IP和SDH设备，使用三元表示来描述每个可用性度量，具有乐观值，标称值和保守值。可用性模型已应用于不同的典型传输网络场景。执行了几个案例研究，以比较不同弹性机制的端到端连接可用性和所需的网络容量。

General availability model for multilayer transport networks

This paper reports the initiative taken within the IST-project NOBEL to define a general availability model and collect general availability numbers for several network equipment types, independent from vendor specific product information. The model includes optical layer equipment as well as IP and SDH equipment, described using a triplet-representation for each of the availability measures with optimistic, nominal and conservative values. The availability model has been applied to different typical transport network scenarios. Several case studies were performed to compare the end-to-end connection availability and the required network capacity for different resilience mechanisms.
