Hi Guys,
Thanks a lot for the discussion. I should put the design earlier for review,
and sorry for the delay. Here is the link for the design doc:

Short summary for the feature design:

Hi Robert/Nir,
Thanks very much for the quick and detail reply, and sorry for that I didn’t
make the whole feature clearly. Actually, it’s our Secondary IP feature, which
is a big feature that will bring change to all the components in the Traffic
Control. I thought our teammate reviewed the
I agree with Nir, it's not as simple as changing a structure to `[]URL`,
it's a bigger architectural design question.
How do you plan to mark caches Unavailable if they're unhealthy on one
interface, but healthy on another?
Right now, Traffic Router needs a boolean for each cache, it doesn't
Hi Eric/Neil,
Isn't the question of supporting multi interfaces per server a much wider
question? Architectural wise.
What would be the desired behavior if the monitoring shows that only one of
the interfaces is down? Will the router send traffic to the healthy
interfaces? How?

The use case behind this question probably deserves a longer dev@ email.
I will oversimplify: we are extending TC to support multiple IPv4 (or multiple
IPv6) addresses per edge cache (across 1 or more NICs).
Assume all addresses are reachable from the TM.

When you say different interfaces, do you mean IPv4 versus IPv6? Or
something else?
If you mean IPv4 vs IPv6, we have a PR for that from Dylan Volz

I'm hoping to get to it early next week, just haven't found the time to
review and test
I’ve got this.

Dear podling,
This email was sent by an automated system on behalf of the Apache
Incubator PMC. It is an initial reminder to give you plenty of time to
prepare your quarterly board report.
The board meeting is scheduled for Wed, 18 April 2018, 10:30 am PDT.
The report for your podling will form
Hi,
Currently, we poll exact one URL request to each cache server for one
interface, but now we’d like to add multiple interfaces support, therefore, we
need multiple requests to query each interface of the cache server, I check the
code of Traffic Monitor, it seems we don’t support this kind
