An efficient, flexible P2P file transmission management technology for limiting and directing of P2P file transmission mainly by replacing an original tracker server with a setting controllable tracker server, and modifying node list based on predetermined rule in the controllable tracker server. With the present invention, a network operator can strengthen function of the controllable tracker server in P2P communication gradually by weakening function of the original tracker server in P2P communication gradually, and utilize various rules or policies established in advance to manage file transfer of P2P nodes.

P2P file transmission management method and system

The present invention discloses a method and apparatus for dynamically subscribing to management information and a method and system for dispensing management information. According to the present invention, a management topic and a participant associated with the management topic may be dynamically determined, and the management topic may be subscribed to for the determined participant. Therefore, it is possible to sufficiently utilize a publish/subscribe mechanism in dispensing management information in a case where the intelligence of the managed device is unequal to the intelligence of the managing device, thereby avoiding creation and utilization of an additional management channel and significantly reducing the complexity and management cost of the system.

Dynamically subscribing to management information and method and system for dispensing thereof

A method for controlling a pipeline-based processor. The method includes determining a change in a workload.
