             Summary: Dynamic assignment of max-ip address in DNS answer parameter for DNS routed services
                 Key: TC-387
                 URL: https://issues.apache.org/jira/browse/TC-387
             Project: Traffic Control
          Issue Type: New Feature
          Components: Traffic Router
            Reporter: Ryan Durfey
            Assignee: Jeff Elsloo


Currently when we build a DNS routed service there is a parameter assigned called maximum IP address which determines how many cache IPs in each cache group should be handed out to the DNS system for the client.  This determines the number of caches across which content is assigned. For small services we typically assign 1-2 caches for larger services we assign 3-5 caches.  

This is currently done manually and if a service grows rapidly they could be handling a large volume of traffic and only have one cache in each group assigned.

I would like to consider some type of feedback loop which gages the popularity of a service and dynamically adjusts the number of cache IPs handed out.
