Dear martin,
Thanks for your reply. We just think when the network environment contains
more than 2 NOXs, what is the behavior between them? So, NOX do not do the
load balance currently?
By the way, We still have some questions which need to your help.
1) What is the process that NOX want to build its controlled OpenFlow
switches topology? NOX will send an event to notify all controlled OpenFlow
switches, then all OpenFlow switches will send LLDP out from their owned
ports to all connected switches?
2) The discoveried topology will be stored on NOX?
3) Support we have a network topology, which showed below, these OpenFlow
switches are all controlled by one NOX. What do the NOX write into the
flowtables of these OpenFlow switches when user ping host2 from host1?
host1 -- ofsw1 ------- ofsw2
| |
| |
ofsw3 ------- ofsw4 -- host2
We really appreciate to all the help you gave us.
Best,
JW
