<p>PROBLEM TO BE SOLVED: To provide a system for efficiently reinforcing a connection hold capacitance at a node by forming a class, which is not more sensitive concerning delay, while using a data buffer for a node inlet and utilizing the difference of allowability in delay between traffic classes. SOLUTION: A data packet according to the parameter of regulator 16 is stored in a data buffer 42 at a former 28. When a token can be utilized for both a former token buffer 44 and a Ps line 46, a coupling circuit 48 outputs a specified data packet from the former 28. The former token buffer 44, which can hold BTS pieces of tokens, received tokens at a rateγsucceeded from the regulator 16 and a Ps line token buffer 50, which can hold a single token, receives a token at a peak rate Ps (Ps<=P). This token is used when outputting the data packet from the former 28.</p> |
