餐馆联邦一次运行的时间推进序列 （按时间排序的时间推进请求和time grant序列）

 

通过在源文件中加入System.out.print("Consumption-NER:-"+_logicalTime+"    "+System.currentTimeMillis())类似的方式在标准输出设备上输出所有NER，TAR和time grant事件及其发生的系统时间点。然后在具体运行各个联邦成员时，把标准输出重定向到文本文件中，再把各个联邦成员产生的文本文件合并。导入到Excel中（分隔符为空格）。然后在Excel中按第二列（系统时间）排序，就得到了下面的事件时间序列。下面列出了从系统开始运行，逻辑时间为0到逻辑时间50秒内发生的事件序列。

 

首先看一下与时间推进有关的各个联邦的参数列表

 

联邦成员 时间推进方式 步长 lookahead

 

Manager TAR 1.0 0.01

 

Productioon NER 0.01

 

Transport TAR 1.0 0.01

 

Consumption NER 0.01

 

Viewer TAR 1.0 0.1

 

其中，Viewer不是时间调节的，其时间推进被忽略。则Manager和Transport都为TAR方式，而Production和Consumption都为NER方式。Manager以墙钟时间推进，因此在发出TAR请求之前，考虑了slppeTime，以确保其在整数秒发出TAR请求。

 

 

注意，对于TAR方式的时间推进，RTI会如下处理：

 

• The federate invokes this service to request its logical time to be advanced to T

– All RO messages in the RTI’s internal queues, and all TSO messages with time stamps £ T, are delivered to the federate after TAR(T) has been invoked

– If no other TSO messages with time stamps £ T are forthcoming (or will be generated by another federate later), the RTI calls the federate’s Time Advance Grant procedure with parameter T to indicate that the federate’s logical time has been advanced to T

 

 

注意，对于NER方式的时间推进，RTI会如下处理：   

• After the federate F invokes NER(T):

– The RTI delivers all RO messages in its internal queue

– If no present or future TSO message has a time stamp  <=   T, the RTI invokes the federate’s Time Advance Grant procedure indicating that the federate’s logical time has been advanced to T

– Otherwise, the RTI will deliver the next smallest TSO message destined for F (with time stamp T ´ <=  T) and all other messages with time stamp T ´ ; then the RTI calls Time Advance Grant procedure with parameter T ´ , and the logical time of F is advanced to T ´
