METHOD FOR SETTING UP PATH OF MULTI-CONNECTING MULTI-LAYER SWITCH

摘要

PURPOSE: A method for setting up a path of multi-connecting multi-layer switch is provided to simplify the configuration of the hardware by adjusting the switching path with parallel shuffle network comprising the function of a switching element in achieving the parallel shuffle network based multi-connected multi-layer switch. CONSTITUTION: The address of the input/output node of a multi-layer switch is acquired by reading a virtual path identification and a virtual connection identification(401). The point value P necessary for routing is acquired and recorded in the tag(402). The point value P is read in the path tag(403). It is judged whether the point value P is "0"(404). If the point value P is not "0", it is judged whether the point value P is more than alpha(405). If the point value P is "0", the switching element transmits the associated cell to the concentrator and finalizes the path setup(406). If the point value P is more than alpha, the switching element reduces a point value(407), and transmits the reduced point value to a desired switching element(408). If the point value P is alpha or less, the switching element transmits the cell to the associated output terminal(409). The switching element judges whether two cells will be outputted to one associated output terminal at the same time(410). The switching element acquires if two cells are about to be outputted to one associated output terminal at the same time(411).
