面向连接的LLO型分层协议网的性能评价

Performance Analysis on LLO Type of Laying Protocol Networks with Connection-Oriented

在单数据单元确认的条件下,考虑纠错再送,且扩展窗口宽度w=2。对虚拟连接LLO型分层协议网络进行性能分析,得到了数据单元传输总时延的表达式,然后对数据单元的传送总时延进行了模拟试验及分析。实验结果表明w=2、数据单元在数十字节时,网络传输效率明显得到了改善。

Under the condition of window size(w) equaling to two, single data unit acknowledging and error-correcting transmission again, this paper analyses the performance for virtual connection LLO laying protocol networks and obtains the total delay expression for data unit transmission. The final simulation experiments and analysis show that the transmitting efficiency is improved largely when w=2 and the length of data unit is confined to dozens of bytes.
