| 针对分布式异构网络信息共享框架问题，提出了基于P2P-SIP的分层信息资源共享覆
盖网络模型。该模型从7层开放式系统互联参考（OSI）模型的第5层会话层进行信息资源共
享互操作过程建模，
具有两层的“去中心化”的结构，采用CHORD环实现信息资源组织和路由，采用扩展的SIP
协议实现网络节点维护和信息资源共享过程协商。仿真试验结果表明，该模型能够自适应
、自协商地实现信息资源组织、资源发现，能够有效解决传统集中式共享系统带来的单点失
效和性能瓶颈等问题。 |

| Abstract: |
| Focusing on information sharing framework in a distributed heterogeneo
us network,this paper proposes a hierarchical P2P-SIP （Peer-to-Peer-Session
Initiation Protocol） overlapped network model.
This model is based on information sharing interoperation procedure from Session
Layer of OSI（Open System Interconnection）. This model has “none-center” st
ructure with two levels.
It adopts CHORD ring to organize and route information resources. Based on exte
nded SIP, the network model realizes the network nodes maintaining and informati
on resources sharing negotiation. Simulation shows this model can realize se
lf-adaptive and self-negotiating information sharing procedures including info
rmation resources organization, discovery, and this model can also effectively s
olve the problems of single point failure and performance bottleneck in a tradit
ional centralized information sharing system. |
