摘要:

短波通信在短波无线IP令牌环协议网络中存在信道利用率低、令牌周期内数据传输总量小等问题。针对短波数据传输的特点,提出一种优化的短波令牌环网络IP网关数据输入排队模型。理论研究和仿真比较结果表明,该模型能解决信道中资源浪费的问题,实现高优先级数据的优先处理,有效提高网络的数据吞吐量。

Abstract:

The disadvantages of the HF channel is that it causes a low channel utilization ratio in the HF Wireless Token Ring Protocol(WTRP) network, and it decreases the throughput during the token-ring duration. This paper proposes a modified input queuing switches model for IP gateway in this network according to the characters of HF data communication. The theoretical and simulation researches show that this input queuing switches model can solve the problem of channel resource wasting, make the high priority data to be served first and increase the throughput of the whole net.

Key words: Wireless Token Ring Protocol(WTRP), HF wireless IP gateway, input queuing
