scope:

This Technical Report focuses on the survivability of both public and private networks and covers a wide range of potential users. Two frameworks are established: the first for quantifying and categorizing service outages, and the second for classifying network survivability techniques and measures. The performance of network survivability techniques is considered; however, recommended objectives for network survivability performance are not established. Recommendations are made for continuing work on this topic.

Purpose

As a result of growing concerns from the telecommunications community, this Technical Report has been developed to address the survivability of telecommunications networks, including the services provided. The report is a response to the need for a common understanding of, and assessment techniques for, network survivability, including availability, integrity, and reliability. It also provides a basis for designing and operating telecommunications networks to meet users expectations for network survivability. Further this report provides a foundation for continuing industry activities in the subject area.
