摘　　要：网络拓扑结构的动态性,使得节点的加入、退出等因素会引起多协议通用网关传输链路的变化。数据包会被发送到繁忙的链路上,导致丢包的发生,使得分组投递率较低。为此,面向多协议通用网关,设计数据包高效转发算法。根据期望传输次数和链路维持时间对链路质量的评估,获取最佳数据包传输链路。结合网关的多协议属性与缓冲区容量,针对发送方与接收方的协议情况进行统一与映射,基于容量与数据包关系,执行不同的数据包转发方法。仿真结果显示,网关转发数据包所产生的归一化控制分组开销、归一化控制字节开销最大值不超过3MB、0.14MB,分组投递率最小值高达98.1%。可见,该算法的处理效率、带宽利用效率和传输效率均较高,且可靠性与稳定性优越性显著,可以为不同设备和系统间的无缝连接提供高效的支持。The dynamic network topology makes the joining and quitting of nodes change the transmission link of multi-protocol universal gateways.Packets will be sent to busy links,resulting in packet loss and a lower packet delivery rate.Therefore,an efficient packet forwarding algorithm is designed for multi-protocol general gateways.According to the expected transmission times and link maintenance time,the best data packet transmission link is obtained.Combining the multi-protocol properties of the gateway and the buffer capacity,the protocol of the sender and the receiver is unified and mapped,and different packet forwarding methods are implemented based on the relationship between the capacity and the packet.The simulation results show that the maximum normalized control packet overhead and normalized control byte overhead generated by the gateway forwarding data packets are less than 3MB and 0.14MB,and the minimum packet delivery rate is as high as 98.1%.It can be seen that the algorithm has high processing efficiency,bandwidth utilization efficiency and transmission efficiency,and its reliability and stability are superior,which can provide efficient support for seamless connection between different devices and systems.
