An efficient switching device and its method using multiple shared memory

摘要

1. the art that the invention set forth in the claims ; The present invention relates to an efficient will the switching apparatus and method using a plurality of shared storage. ; 2. The invention is to solve the technical challenges ; The present invention can provide, such as the so expanded is easy, and stored once in the storage location output by sharing a plurality of storage locations, as well as power consumption is low the output with respect to the uniform distribution and non-uniform distribution of traffic queue switch structure performance to provide a switching apparatus and method that is an object. ; 3. The gist of the solution of the invention, ; The present invention, in the switching unit for transmitting the data input to the multiple input ports to multiple output ports, determines the output time to read the output port of the data input from the external device determines the output time of the output port Way; The output time control means coupled to the output time determining means to manage the available time data output by the output port of the data; Storage location selecting means for selecting the data output time storage location is empty, position data output by the time (memory bank) of output from said time decision means; Using storage location information management means connected to said storage location selecting means to manage the time using the output of the storage location; Connection means for selecting and passing the transmission data to output the time position of the determined storage location (memory bank) by using the result of the output time determining means and said storage location selecting means; Connected to said connecting means, and stores the data in the output time position of the output time determining means and said storage location selection selected using the results of the means and the determined storage location (memory bank), outputting a plurality of distributed shared storage location to time ( And delimited by management in accordance with), the current output time ( ) In a shared storage means for outputting the read data transfer of the corresponding storage location to; And the current output time of the shared storage means ( ) Receiving the input data corresponding to the outputs comprises an output port connected to means for delivering to the output port corresponding to the read information of the data output port. ; 4. important use of the invention ; Yiyongdoem the invention a switching system or a network system or the like. ; A plurality of distributed storage, shared storage, switching device, the output time determined, storage location selection, uniform traffic distributions, a non-uniform traffic distribution, the output queue switch structure performance
