Mikrotik V6 Beta 1 Released

What’s new in 6.0beta1 (2012-Apr-13 15:26):

*) updated drivers and kernel (to linux-;
*) improved interface management (scales well for up to thousands of interfaces and more);
*) improved queue management (/queue simple and /queue tree) – easily handles tens
of thousands of queues;
*) improved overall router performance when simple queues are used –
at least double the performance of v5, even bigger improvements on multicore systems;
This is going to help those PPPoE folks.
*) very small overhead for packets that miss simple queues,
but simple queues are present in the system;
*) pcq queue is NAT aware (just like “/queue simple” and “/ip traffic-flow”; Excellent.
*) in “/ip firewall mangle” can specify “new-priority=from-dscp-high-3-bits”;
*) new default queue types: pcq-download-default and pcq-upload-default; Will streamline things a LOT
*) simple queues have separate priority setting for download/upload/total;
*) slave flag shows up for interfaces that are in bridge,bonding or switch group; Will help with my memory at 2 AM.
*) global-in, global-out, global-total parent in /queue tree is
replaced with global that is equivalent to global-total in v5; Not quite sure how this will look in practice…too lazy to install it right now…hehehe
*) simple queues happen in different place – at the very end of
postrouting and local-in chains;
*) simple queues target-addresses and interface parameters are joined into one
target parameter, now supports multiple interfaces match for one queue;
*) simple queues dst-address parameter is changed to dst and now supports
destination interface matching;
*) dns cache logs requests to topics “dns” and “packet”; Does this mean that DNS requests hit the log if so desired?

Lots of queue work and apparent streamlining of the OS. Can’t wait to see some post beta versions!

    Ooh. Know what I’m doing tomorrow when I test my Via VB7009s (which had problems under the 2.6.35 of 5.x, but worked under 2.6.37 of Vyatta)!

    Be sure to let us know how it goes!

    Anyone else worried with the direction of RouterOS? There are so many problems with 5.x that I expect 6.x to be much more buggy or a great improvement

    I’m assuming that since there was such a radical hardware change with the CCR that they are doing the integration in V6.
    It also sounds like they are rewriting major portions of the OS, which would probably be better done in a new revision. 😉

    As for the stability of V5, it seems pretty solid on .14 to me. I’ve occasionally still got IPSec issues as well as OSPF instability, but it is not too shabby beyond that.
