Subject: [Cake] tail drop on complete overload
Date: Sun, 12 Apr 2015 15:16:12 -0700 [thread overview]
Message-ID: <CAA93jw7HDGZZMQriWiJvTkLvMYQYE9ZHUJQh-pWtgDn3dg2ehA@mail.gmail.com> (raw)
The full flow space search on complete overload is terribly expensive,
moreover it is not deterministic, and touches a lot of cache.
In a hardware implementation of cake we would probably drop this and
just do tail drop.
The ability to compile with tail drop for this would be useful in
terms of analysis of overload behavior and be less hard on routers
being flooded.
