Research and Implementation of Embedded Intelligent Network Self-Healing Equipment Based on E1 Link

An intelligent network self-healing solution with regard to the current problem existing in the dedicated network was proposed in this paper. The solution can implement the self-healing by introducing intelligent network self-healing devices which were developed and produced on our own between outside and inside networks, without changing of the current network structure. The devices enable the 1+1 hot backup of links and also possess functions such as malfunction supervision, localization, automatic processing, etc.
