We call it TRA just because the name is coincides with Taiwan Railway Administration（臺鐵） and it's fun.
The packet may delay but it will reach the destination, LOL.
TRA (Traffic Realtime Analysis) is an application to fetch packet loss and queueing delay between two network interface.
With TRA, it can sniff receive packet and transmit packet and check the packet is transmit through your service successfully or not.
TRA only support on Linux with libpcap library. Please take a look about Installation part.
TRA need libpcap to build, please make sure that you already have libpcap-dev first.
cmake .
cmake --build
We provide a docker for build environment. It provide two test device and already configure the tra-node as the gateway.

We expected that DEVICE-1 and DEVICE-2 will communicate through TRA-NODE. TRA-NODE will sniff two interface which connect DEVICE-1 and DEVICE-2.
Since TRA-NODE is play as gateway, we expected that the identification value of received packet of TRA-NODE will as same as transmit packet from TRA-NODE. Therefore, we can check every packet TRA-NODE received is transmit successfully or not.
It's good to develop TRA with this environment to test TRA is work or not.
