Abstract: In tactical data link system,the prioritization-based polling access protocol can ensure that information packets in the prioritized sites are sent in time,but the service switching still consumes time.In order to reduce the waiting time and queue length,this paper proposes a Prioritization-based Continuous service Access Control Protocol(PCACP) by using Field Programmable Gate Array(FPGA).The protocol adopts the exhaustive service for the prioritized sites and the limited service for the subordinate sites.The control center adopts the continuous service mode between the sites.The Markov chain and the probabilistic generating function are used to analyze the performance index of the model to obtain the accurate solution of each performance index.The model is simulated by Matlab,and the results show that the proposed protocol can ensure the information packets of the prioritized sites are sent in time,reduce the queue length of the information packets and increase the throughput of the system.

Key words: tactical data link, priority, continuous service, queue length, Field Programmable Gate Array(FPGA)

摘要: 在战术数据链系统中,区分优先级的轮询接入协议能够保证优先站点内信息分组及时发送,但在服务切换过程中将耗费部分时间。针对该问题,利用现场可编程门阵列设计并实现一种具有优先级的连续服务型接入控制协议。对优先站点采用完全服务的方式,对从属站点采用限定服务的方式,对控制中心在各站点之间采用连续服务的方式,从而降低等待时间同时缩短排队队长。在此基础上,引入马尔科夫链和概率母函数对模型的性能指标进行分析,得到各性能指标的精确解。基于Matlab的仿真结果表明,该协议能够保证优先站点内的信息分组及时发送,同时降低信息分组的排队队长,提高系统吞吐量。
