OPTICAL PATH NETWORK, AON CONSTITUTION METHOD NODE, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To reduce the labor and time required for setting a cut-through path and the possibility of ineffective holding.

SOLUTION: When data under IP transfer exceeds a prescribed data quantity, a node autonomously sets the cut-through path. When the data quantity of data transferred by using the cut-through path becomes less than the prescribed data quantity, the cut-through path is speedily released. In addition, a plurality of AONs (all optical networks) closed on the basis of a policy of not requiring 3R (Reshaping, Retiming and Regenerating) processing are respectively constituted of a plurality of nodes. They are properly interconnected, thereby setting a desired cut-through path simply in a short period of time.
