Acceptance determination method and traffic control method and system for implementing a quality assurance service

摘要

PROBLEM TO BE SOLVED: To realize a reception decision making which is safer than decision making using a conventional effective band e_k, and maintains no logical packet loss as it is, improves scalability, and maximizes accommodation efficiency.;SOLUTION: The reception decision method of a service providing network that provides an inter-UNI quality guarantee by making UNI traffic definitions of traffic characteristics of a session flow from a device in a user network to the service providing network includes a procedure (201) of grasping connection information and link resources of respective trandfer nodes, a procedure (204) of employing a value e_k common in a network for an effective band to be allocated to each session flow (k) without depending upon a link ij (calculating the e_k from a procedure of calculating D_min), procedures (206 to 208) of comparing a link band C_ij with the effective band total value Σe_k of all session flows to decide whether reception is allowed, and a procedure of deciding whether the reception is allowed by using a relational equation σ_k=r_kD_min.;COPYRIGHT: (C)2006,JPO&NCIPI
