Title: Non-periodical bidding method, path price determining method using the method, communication quality control method, and device, and program
Inventor: TERADA KENJI
IPC: G06Q50/00
Filed: 2001-01-25
Abstract: PROBLEM TO BE SOLVED: To provide determination of a charge in usage of multiple providers by calculating a charge per path, and to eliminate a necessity of checking whether or not quality of communication is maintained by not making a contract by an SLA and having the quality determined by responsibility on a user side. SOLUTION: In regard to a usage charge distribution problem, a user starts a process from a presentation of a value standard to a path via a user agent 100, ultimately performs bidding per path, and determines a price per path. The user has only to pay a user charge in accordance with the price determined by the bidding to a provider 200 managing the used path, and distribution of the usage charge to the provider 200 is determined by a supply and demand relationship. Since the communication quality is not guaranteed by responsibility of a provider 200 side to a demand of delay time of an SLA contract, necessity to pursue causes or the like can be eliminated. A provisioning agent(PA) 300 proposes a path candidate based on a topological DB and presents it to the UA 100.
