针对目前以光突发交换(OBS)为基础的光子网格(grid)网络中基于客户/服务器(C/S)模型的资源管理技术的缺点,在已有工作的基础上提出了一种改进式的基于P2P技术的自组织资源管理技术。该技术利用P2P的特点以及通过对资源所进行的特定描述,从而使资源信息分散存储在多个节点上,同时利用该技术可以较快地实现资源查找。仿真结果表明,该方案不但可以解决传统C/S资源管理方案扩展性不足和容错性较差的缺点,同时可以进一步地缩短资源查找时间,因此可以更好地支持未来面向普通消费者群体的大规模网格业务。
In order to avoid the problems of client/server(C/S)-based resource management scheme in grid over optical burst switching(OBS) networking,an improved self-organized resource management mechanism based on the peer-to-peer(P2P) technology and the previous works was proposed.By utilizing the P2P technology and special descrip-tion of resources,the proposed mechanism could achieve distributed resource information storage and fast resource dis-covery capability.Simulation results show that the proposed mechanism can not only address the issues of poor scalabil-ity and fault-tolerance introduced by traditional C/S-based schemes,but also reduce the time for resource discovery.Therefore,it is more suitable for future large-scale consumer-oriented optical grid applications.
