------------------------------
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.
