Public bug reported:
[Existing problem]
Currently, neutron will treat all l3 agent as the same. The default
LeastRoutersScheduler will chose l3 agent, based on the load of l3 agents. But
the hosts of l3 agents may be different. Some hosts may have better CPU, larger
memory and better network bandwidth. Admins/Operators may want the host with
higher performance to take more load.
[Proposal]
Add a configuration to l3_agent.ini to represent the weight of l3 agent.
Admins/Operators can set higher weight to the l3 agent with higher performance.
The l3 agent with higher weight will have higher chance to be selected by the
L3Scheduler.
[Benefits]
Neutron can provide a better scheduling by leveraging the difference of
performance of l3 agents' hosts
[What is the enhancement?]
Configuration file changes.
Code change in the L3 scheduler.
