Hi,
I am in the process of testing an 'automation/sdn' kind of controller, it will be managing configuration on our routers and also deploying some VNFs too.
Before accepting it, i'd like to perform some testing, to make sure of the behavior if there are network issues between the controller and the devices (routers or servers), during creation of services.
From the top of my head, I can think of the basic tests like introducing jitter and delay but i would appreciate more ideas or even test cases that i can re-use.
Thanks
Hi,
For sure you need to check failover scenarios, reboot the controller or isolate it during some time.

Can they get split-brained? -- Hugo Slabbert | email, xmpp/jabber: hugo@slabnet.com pgp key: B178313E | also on Signal
