Abstract: P2P network is one of the research hotspots in current time, which is considered as the foundation of next generation network. The paper introduces a transaction management strategy in hybrid network. The strategy utilizes the power of super-peer. Super-peer manages the transactions scheduling on common peers. Common peers check conflict among transactions and send messages to super-peer. According the messages, super-peer schedules transactions in order. The paper demonstrates and simulates the transaction management model.

Key words: P2P network, strategy, transaction management model

摘要： P2P网络是当前网络研究的热点之一，被认为是构建下一代网络的基础。该文基于混合式结构的P2P网络提出一种事务管理策略。该策略利用P2P网络中的超级节点处理能力强的特点，由超级节点管理普通节点上的事务调度。普通节点检查事务之间的冲突并向超级节点发送事务冲突消息。超级节点根据冲突消息确定事务之间的依赖关系，合理调度事务。并对提出的事务管理模型进行论证和仿真。
