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 at 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

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?
