A system and method for automatically restoring a network which contains a node with a failed switch. Protection cycles are generated for the network to be restored and cyclegroups are generated from the protection cycles. Each node is provided with protection switches which internally interconnect the input / output ports to connecting links via interconnecting protection fibers. The selection of which internal protection fibers upon which to switch transmitted information onto allows the node to be configured to create merged cyclegroups. Thus if a failure in the central switch is detected, the transmitted information is diverted to a selected protection fiber corresponding to a merged cyclegroup so that the information can be automatically passed around the failed switch via the protection fibers. Each protection switch has associated mapping data which defines which protection fiber will be switched to based upon the input and output link for the transmission that is required to be sent through the node. The system and method applies to non-planar networks as well as planar networks.

Method for computing all-terminal reliability for arbitrarily interconnected networks such as the United States public switched telephone network. The method includes an efficient search algorithm to generate minimal cut sets for nonhierarchical networks directly from the network connectivity diagram. Efficiency of the search algorithm stems in part from its basis on only link failures. The method also includes a novel quantification scheme that likewise reduces computational effort associated with assessing network reliability based on traditional risk importance measures. Vast reductions in computational effort are realized since combinatorial expansion and subsequent Boolean reduction steps are eliminated through analysis of network segmentations using a technique of assuming node failures to occur on only one side of a break in the network, and repeating the technique for all minimal cut sets generated with the search algorithm. The method functions equally well for planar and non-planar networks.

A farming system compensates for soils that drain too well by underlaying the crop fields with a planar network of liquid reserve matrices. These are placed at the bottom of the root zone, below the level that ordinary seasonal tilling will reach.
