Abstract (in Japanese) (See Japanese page) 
(in English) In the information communication network,it is required for a detour path to be node-disjoint regarding a working path in case of a node failure occurs.
Additionally, the previous research has indicated that fast failure recovery might be realized by using local node-disjoint paths that connect two nodes neighboring the failure node.
This paper discusses a calculation method of local node-disjoint paths.
By defining an edge set which forms a cycle as a tie-set,
local node-disjoint paths are calculated by using tie-sets whose exclusive-OR leads to a single tie-set.
However, an exclusive OR of arbitrary tie-sets is not always a tie-set.
Hence, this paper proposes the concept of overlapping degree as a sufficient condition that an exclusive-OR of two tie-sets must becomes a tie-set and discusses its property.
Finally, this paper shows the comparison results of a proposed method and a simple method using shortest path algorithm.
