A New ATM over SDH Network Survivability Scheme Based on failures

摘要

The more and more telecommunication networks are constructed with multi-techniques. This paper looks at several aspects of survivability ATM over SDH networks. Considered the specialty of ATM over SDH networks architecture, and focused on meshed networks, we proposes a new ATM over SDH network survivability scheme based on failures for the multi-layer networks: using failure-case-oriented restoration/protection implementations in order to meet the demands for the survivability of networks.
