IPv4 routing table call function in pythoh bindings

[yang li]

Hello, dear all experts

It seems like the method to utilise IPv4 route helper to print out routing table can be :

   // Trace routing tables
    Ptr<OutputStreamWrapper> routingStream =
        Create<OutputStreamWrapper>("dynamic-global-routing.routes", std::ios::out);
    Ipv4RoutingHelper::PrintRoutingTableAllAt(Seconds(10), routingStream);

or
   Ipv4RoutingHelper::PrintRoutingTableAllEvery(Seconds(0.5), routingStream);

According to example from the source code, however, I tried to use python bindings to generate the routing table also, but I can not convert them based on my experience:

routingStream =ueNodes.GetObject[ns.core.OutputStreamWrapper]().__deref__()

ipv4RoutingHelper.PrintRoutingTableAllAt(ns.core.Seconds(10), routingStream)

Any instructions or advice would be grateful since routing table is a really good method to identify the transmission flow here.

Hi, I bring some update

It seems like the outsreamwrapper should be correct, but somehow the time can not be converted to acceptable format in python bindings, which I do have clue what the type of time format

is this printingroutingtableallat() expecting from the program:

AsciiTraceHelper=ns.CreateObject("AsciiTraceHelper")

routingStream = AsciiTraceHelper.CreateFileStream("ttttttt.routes")

# Create a Time object for printing the routing table at 10 seconds

print_time = ns.core.Time(ns.core.Seconds(10.0))

# Print the routing table at the specified time

ipv4RoutingHelper.PrintRoutingTableAllAt(print_time, routingStream)

#####

ns.core.Simulator.Run()

flowresults()

ns.core.Simulator.Destroy()

Can you attach the entire script code? Makes my life easier

Hello, drear Gabriel

I apologise for incomplete information here, I will attach my major program file (draft 44) and dataset to generate the mobility for nodes (full-data-set.csv)

I am actually also trying to get Netanim file, it seems like it could generate a XML file with my simulation, but basically the output file does not have many measurements, it seems like I need to set the position of nodes also, but trying to work on how my nodes with racing car dataset can be done by Netanim.

Hello, dear experts

I wonder if there are some methods to understand the routing flows by reading the flowmonitor output file,

I also tried to use Netanim to figure out how the data flows from one UE to another one.

I attached the measure file so you could check what it is going on in my project traffic
