Failover with zero packets lost #66

Open gorzelak opened 8 years ago

gorzelak commented 8 years ago

Hi,

In my scenario I have two WIFI connections, Ubuntu 15.10 and latest MLVPN.

When I test my configuration by connecting or disconnecting one of my WIFI routers I can see that several (2-3) ping packets are lost. At the same time all open tcp multimedia streams get disconnected.

My mlvpn.conf on both side (server and client) have such lines:

timeout = 3 reorder_buffer_size = 64 loss_tolerence = 1

Is it possible to build a "bulletproof" failover solution (zero packets lost)?

Thanks in advance. Krzysztof

I'm also interested in similar solution

It's not possible to have zero packet loss with current implementation.

It could be done by having ACKs or by implementing packet duplication on all links.
