摘　　要：消息数据高效传输是混合式网络的一个研究重点.发布/订阅模型实现了消息发布者和消息订阅者之间解耦的消息传递模式,适用于混合网络之间的消息数据传输.通过将发布/订阅模型应用于消息数据交换,规范了消息数据的格式,实现了对各类通信设备的灵活管理以及基于消息内容的动态数据路由;并利用一种基于循环调度的动态负载均衡算法,对低速率网络和高速率网络之间的性能进行合理调度,提高了低速率网络的性能.模拟实验结果表明,在混合式网络中发布/订阅模型能实现可靠的消息数据交换,在负载平衡算法下性能更好.Efficient transmission of message data is a research focus of hybrid networks.Publish/subscribe is the messaging pattern to realize the decoupling between publisher of messages and subscriber of messages,which is suitable for message data transmission between hybrid networks.By applying the publish/subscribe model to message data exchange,the format of message data is standardized,flexible management of various communication devices,and dynamic data routing based on message content.Along with publish/subscribe,a dynamic load balancing algorithm based on the round-robin scheduling is proposed to improve performance of low-rate networks.Simulation experiments are carried out,and the experimental results show that publish/subscribe model achieves reliable message data transmission between hybrid networks,and it performs better with load balancing.
