Embodiment Construction

[0016] The present invention comprehensively uses object-oriented, multi-layer system structure, discrete time simulation, event simulation and data flow simulation technology to define the technical framework for the simulation of P2P network, and constitute the multi-level structure model of P2P network; The first layer provides an independent event container; and then uses the multi-state self-describing model to provide object-level abstraction for the system state, so that a single system can use the event container to accommodate multi-state objects to simulate the coexistence of multiple states in a real system. For blocking states , it is necessary to provide an independent state object container for processing; the present invention also abstracts all behaviors and states of the system into objects, uses the inheritance method in object-oriented, provides a unified processing interface for all objects, and ensures the consistency of event processing. The event characte...

Abstract

Disclosed is a design method of an extensible general P2P network simulator; firstly, the technology frame is defined for the simulation of the P2P network to construct a multilayer structure model of the P2P network; and then a separated event container is provided for each layer of the multilayer structure; the abstraction in the object level is provided for the system state; the system is enabled to use the mode that the event container contains multimode objects to simulate the multimode coexistence in the practical system; finally, all the behaviors and states of the system are abstracted to be objects; all the objects are provided with unified processing interfaces to guarantee the consistency of the event processing. The design of an extensible general P2P network simulator provides the P2P protocol realized in the simulator with the unified abstraction process through the unified system behavior abstraction method and simplifies the simulation realization cost of the practical protocol; compared with the prior art, the design method of an extensible general P2P network simulator has the advantages of simulating the behavior features of the practical P2P network system completely, providing the simulator with good extensibility, usability and generality.

Description

technical field [0001] The invention relates to a P2P network simulation technology, which is a design method of an expandable general-purpose P2P network simulator, which is mainly suitable for the simulation of the P2P network, and can also support the design of other distributed system simulations. Background technique [0002] P2P network has developed rapidly and been widely used in recent years, and its data traffic has occupied the main body of Internet traffic. Due to the large scale and high dynamics of the P2P network, there are problems of complex structure, difficult control, excessive overhead and weak versatility in the performance analysis and evaluation of traditional simulation experiment methods. In view of this reason, the research of peer-to-peer network simulation technology and development are receiving increasing attention. [0003] At present, although there are a variety of network simulators for different application environments and different prot...
