VIRTUAL CHANNEL MERGE APPLICATION METHOD ACCORDING TO AMOUNT OF VIRTUAL CHANNEL LABEL USE

摘要

PURPOSE: A virtual channel merge application method according to the amount of virtual channel label use is provided to receive a network enlargement side and reduce a delay problem by a cell interleaving. CONSTITUTION: When a virtual channel request signal is received at the upper layer, it is discriminated whether a system applies a VC(Virtual Channel)-merge. Thereafter, the size(SN) of VC label allocation region of a port for outputting the input VPI(Virtual Path Identifier)/VCI(Virtual Channel Identifier) is compared to a lower critical value(T1)(31). If the size(SN) of VC label allocation region of the port is larger than the lower critical value(T1), the size(SN) of VC label allocation region of a port is compared with the upper critical value(T2)(32). If the size(SN) of VC label allocation region of a port is larger than the upper critical value(T2), the VC-merge does not operated(34).
