ASYNCHRONOUS TRANSFER MODE SWITCHING SYSTEM CAPABLE OF MERGING HIGH SPEED VC AND VC MERGE CELL IDENTIFYING METHOD APPLIED TO THE SAME

摘要

PURPOSE: An asynchronous transfer mode switching system capable of merging a high speed VC(Virtual Channel) and a VC merge cell identifying method applied to the same are provided to identify a retrieval pointer of a transmitter with a storage pointer of a receiver, thereby extracting the same packet cells without delay of VC-merged cell stream. CONSTITUTION: A merge transmission scheduler stores received cells in a queue(401), and transmits information cells having a VC-merge start state(402). The scheduler sequentially transmits the stored cells(403). When cells to be transmitted do not exist, the scheduler calculates the number of pairs, and transmits information cells with continuing states(404). The scheduler transmits information cells with end states(405), and initializes a queue management pointer(406). The scheduler sequentially stores general cells in an input queue(407). The scheduler changes the queue management pointer(408). The scheduler initializes the input queue(409).
