[confidential]

Dear Fiware Lab Helpdesk

Hi, I'm a one of FIWARE Lab Noida Node user in Japan.
The network condition between my PC and VM on Noida Lab seems not good.
I have tested following scenario to confirm network condition.

[scenario]
PC(Japan) --------->> Network ----------->> FIWARE Lab VM(India)
114.179.233.245 180.179.214.169
1. Send 100MB file from my PC to FIWARE Lab VM with scp and measure the elapsed time.
2. Repeat above operation 5 times and obtain following result.

[result]
[root@fiware1 ~]# time scp 100MB_File lab:/home/centos
100MB_File 37% 37MB 2.0MB/s 00:31 ETApacket_write_wait: Connection to 180.179.214.169 port 22: Broken pipe
lost connection

real 0m24.177s

[root@fiware1 ~]# time scp 100MB_File lab:/home/centos

real 0m1.910s
user 0m0.002s
sys 0m0.005s
[root@fiware1 ~]# time scp 100MB_File lab:/home/centos
100MB_File 0% 0 0.0KB/s -:- ETApacket_write_wait: Connection to 180.179.214.169 port 22: Broken pipe
lost connection

real 0m5.951s
user 0m0.003s

I tested above scenario and noticed network condition isn’t good.

[request]
Could you tell me why network condition isn't good if you know something?
