Dual WAN failover/NAT issue

I'm testing a dual WAN fail-over setup using this method: http://wiki.mikrotik.com/wiki/Advanced_Routing_Failover_without_Scripting I have two Internet connections going into an RB750G. One link is normally used for computer traffic, and the other is used for VOIP traffic. When one link fails, the t...

Re: PCQ question

I can confirm it is working as fewi explained. This is good stuff, it transformed that segment of the network. I'm excited to try this on a large scale.

Re: PCQ question

Yes that is what I am seeing on my test machine at the site, but my test end user seems to be reporting differently. He may be having other issues. I need more data from other end users but its a little hard to get. Once I figure this out for sure, I'll post what I find.

Re: PCQ question

Thanks, I did see that and I do understand the basic concept, but the examples do not directly relate actual throughput to max-limit (its not specified whether the queue rates shown are potential or actual), so I was unsure what should happen when actual throughput < max-limit. I need to know the pr...

Re: PCQ question

Thank you. So, just to be absolutely clear, it doesn't matter if max-limit has actually been reached or not, queues will always get limited to max-limit / queues? So, the solution to let users get closer to the actual specified PCQ rate (at times when max-limit / queues would be less than rate, but ...

Re: QoS and Queue Tree

I don't believe your FTP rules are really having any effect since active FTP transfers data over tcp port 20 and passive FTP uses a random port > 1024 to transfer data.

PCQ question

I have a question in regards to PCQ. Say I have a PCQ queue with a 2Mbps rate and max-limit of 10Mbps. If I have 20 queues, does bandwidth get managed such that each user could download at a maximum of 500k (10Mbps / 20 queues), which would make hitting the 2Mbps rate only truly possible when there ...

Re: High speed bridge

Some results from initial testing, starting out small. Bandwidth manager is a Supermicro P4 3.0Ghz system with two Intel GigE cards. 83 mangle rules that mark and prioritize traffic, includes use of MT all-p2p filter. 1 queue tree with 3 pcq sub-queues managing bandwidth in the download (toward end ...

High speed bridge

I was wondering if anyone has experience using MT as a transparent bridge doing QoS (PCQ, DSCP, marks, etc . . .)/prioritization on a large scale, i.e. thousands of users and 300-400Mbps+ of traffic. Possible with the appropriate x86 hardware? Just to throw a number out there say 50-100 mangles.

Packets being dropped/latency

I am using RouterOS as a transparent bandwidth manager (via PCQ) over two bridged nics on a x86-based system. At peak load, the CPU runs around 10% pushing a few thousand PPS at around 60Mbps. We are seeing dropped packets and periods of high latency, even for traffic the bandwidth manager should be...

PPPoE performance guidelines

I am looking to put together an x86-based router that will need to terminate approximately 300-400 PPPoE sessions. I will be rate-limiting P2P traffic and possibly some other types of traffic. Possibly might have a few other firewall rules. Peak times will see 100-150Mbps of traffic. Any general gui...

Re: Ros V5 beta new intel drivers

It's already supported, it's automatically used if it's supported by the card. See previous posts.
Ah ok, I wasn't quite clear. Thanks!

Re: Ros V5 beta new intel drivers

Are there still no plans for MSI-X support? Lack of support for that would be an immediate deal-breaker for me, so I would like to know for sure. I hope you have reconsidered, RouterOS otherwise looks to be quite capable.

Re: Performance question

Turbo-boost is good for a few hundred Mhz, AFAIK, which is likely going to be far from providing a large performance increase (my guess would be maybe 10% at most). Other than that, i7/X34xx have essentially the same architecture, save for the X34xx ability to use ECC RAM. Regardless, i7 is not an o...

Re: Performance question

i7 is quad core/HT . . . and 2.8Ghz is about the upper limit as far as server-class hardware, unless you want to pay massive premiums for small increases in speed.

Re: Performance question

I will have full routes to the Internet and probably a few hundred internal routes. There will be no QoS, firewall, etc . . . these are just transit routers.

Re: Performance question

What I'd like to try to find out is what I could realistically ramp up to. We have Gbe connections to two different carriers. There would be two routers, each would terminate one carrier. Currently, we run about 200Mbps per carrier at peak time.

Performance question

I am looking at replacing our aging Cisco 7206VXR border routers with servers running RouterOS. CPU-wise I am considering Xeon X3460s, 2.8Ghz quad-cores with hyper-threading support. Network cards will be Intel E1G44ETs. I will be running BGP and OSPF. Does anyone have a similar setup? I'm wondering...
