Title:
TRAFFIC SHAPING DEVICE FOR ATM COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP3436984
Kind Code:
B2
Abstract:
PURPOSE: To change a schedule without influencing communication during service by constituting a schedule memory by an active surface and a standby surface and providing a control means for arbitrarily switching and accessing both surfaces.
CONSTITUTION: An Sc memory access control part 2 controls the read, rewrite and maintenance read of the Sc data of a schedule(Sc) memory 1 composed of surfaces A and B. For instance, the surface A of the memory 1 is defined as the active surface, the surface B is defined as the standby surface and while reading the Sc data from the surface A and performing the service, the rewrite and maintenance read of the surface B are performed and the different Sc is set. Also, the surface B is switched to the active surface, the surface A is switched to the standby surface, the Sc data are read out of the surface B and the service of the new Sc data is provided. Thus, even when it is required to update the Sc during communication service, the different Sc is set without influencing a user at all.
