The new switches look pretty amazing

Would pair of LHG XL 52 ac be decent replacement for pair of QRT2, for PtP ? Using QRT2s because of tree foliage, haven't tried 5GHz yet in those conditions.

5GHz is more prone to obstacles than 2.4GHz, it is already lucky that your link works behind foliage, usually it is a big problem for wireless links. Maybe some fresnel lines manages to establish the link but fresnel is also narrower in 5GHz.
Anyway, almost every situation is particular in wireless so if you can afford it might be worth a shot. I have had one situation where a 5km point to point had a hill in its line of sight, just the top of the hill, but it still managed to connect at 5GHz, obviously the upper fresnel zone was helping it.

LHG XL 52 ac is nice, but really interesting is a 60GHz / 5 GHz combo.

I still think there should be more emphasis on the fact that a CRS is not a L3 switch (comparable to L3 switches from other manufacturers).

Now take the 5G router and add a 802.11ax chipset with your new MU-MIMO driver Reinis is currently working on... (add OFDMA support later)

Update: Just saw this video: http://straume.lmt.lv/lv/notikumi/notikumi/5G/1043237
So the router exists already?

And there´s also a kind of LHG with 5G logo:

LHG XL 52 ac is dual band or dual card (interface) device ?
Look like dual card for this paragraph in news

y. You can easily setup the 5 GHz channel as the main one with speed up to 600
Mbps and use the 2.4 GHz channel as an automatic backup connection with speed up to 260 Mbps or use both
connections at the same time for load balancing.

Of course.
But, I was refering to 2.4GHz QRT2 vs 2.4GHz LHG XL 52 ac. Is it possible that I could potentially see improvement in that area, if 5GHz option fails ?

LHG XL 52 ac ... possible FDX download for 5Ghz interface & upload for 2,4Ghz interface ? Real FDX? Many places / towers don't have free spectrum for UPLOAD.

Of course.

Not necessary. If I recall it correct, LHG shoud be a bigger antenna than QR2, that means a narrower beam distribution. It depends on the antenna characteristics and beam forming of it.

Hi,

About the Q+BC0003-S+. It says you can connect this to 4 other devices. How do the interfaces look like on the CRS326-24S+2Q+RM
when you connect this to 4 other routers ? The 40G ports acts like a switch? How would you set this up ?

LHG XL 52 ac ... possible FDX download for 5Ghz interface & upload for 2,4Ghz interface ? Real FDX? Many places / towers don't have free spectrum for UPLOAD.

Yes, you can do that AND achieve redundancy as well. There's an article about it in the wiki:
https://wiki.mikrotik.com/wiki/Dual_Setup_with_OSPF

You can choose between our legendary feature-packed RouterOS for booting or a simpler, but still powerful SwOS.

I LOL'd. Legendary in terms of what - the ROS v7 joke?
But the new switches are imho really sexy! Just fix the software please

So complaining about non-existing OS, instead of enjoying the features you have available since 1997 ?

About questions from tangram:

The QSFP+ interfaces are as follows:
qsfpplus1-1 qsfpplus1-2 qsfpplus1-3 qsfpplus1-4
qsfpplus2-1 qsfpplus2-2 qsfpplus2-3 qsfpplus2-4
The ports can be configured as you wish, for example you could connect Q+BC0003-S+ to 4 different CCR's, and just bridge the 4 interfaces together, and now all off them are bridged together. When using direct QSFP+ to QSFP+ connection, only first interface - qsfpplus1-1 or qsfpplus2-1, will be used at 40Gbps rate. When using Q+BC0003-S+ you will have to set the speed to 10Gbps for all 4 interfaces. We will soon update wiki on how to configure QSFP+ interfaces

Just received the email version of this newsletter. It seems broken, no links work.

Amazingly low price on the 40G stuff.

Thanks for explaining this, I'll look forward to wiki update.
This new CRS looks awesome!

That's what original NSTREME dual was used for. And it will probably work in this way too, you can use two different interfaces and set one to TX and other to RX (and vice versa on the other side of the link). Throughput also increases because there is no need to ACK packets by receiving station on same frequency, no need for radio to constantly switch from rx to tx, no TDMA... just real full duplex link.

LHG XL with two 5G radios would be interesting as well, so different channels could be used on both ends of the link, like it's common on higher licensed bands...

Really?? You probably mean that there is no need to send the ACK packets from a TCP connection over the same link, but does this solution also send the ACK packets at 802.11 level over the other link?
I would be very surprised when it does that. More likely is that the transmit/receive still switches at 802.11 link level, to receive those ACKs, but then the L3 and higher traffic in opposite direction is sent over the other link. Which of course also brings benefits, but real full duplex it isn't.

It's Mikrotik proprietary protocol, it doesn't use 802.11 ACKs at all, only data frames with custom protocol over it. It works same as usual nstreme, but with duplex channels/separate tx/rx paths.
If you sniff the nstreme link on air, all you get are data frames. ACKing and frame repetition, if required, is done on the higher level (custom mikrotik protocol). Same for CSMA, it's not used at all.

With these 40G High-Speed Ports we will get quite big speed differences into the network. So Buffering/Flow Control will be an issue/must have.
We saw this while upgrading our main uplink to 10G. Using CRS317 we even cant see the flow control negotiation status. We got packet loss in the direction of slower links with bursty traffic. So even on non congested links we got packet loss.
@MT might be the time to add flow control status to interface status.

Normis: When will the CRS354 finally hit the surface?
It was presented as upcoming already at the Berlin MUM some 17 months ago

never, CRS356 never even exist....
however crs354 should be available around q4 this year

Yes, I wrote wrong name, corrected my post, sorry. Somehow I believed that name was changed alongway, but never mind, we are talking about the same beast.
Either way, I wonder why this model took so long to finish...?
Q4/19 announced at the Vienna MUM...according to normal delays that means that we will see 2020 before distributors have it in stock....

No, it only links the routers together, it has no software itself. It's basically an adapter.

:

• PWR-LINE PRO

Download the newsletter here:
https://download2.mikrotik.com/news/news_90.pdf

Most Power-Line adapters made by the competition are sold in packages that contain 2 adapters.
Its not clear to me if the PWR-LINE PRO package contains 1 or 2 adapters --- please clarify.

Single unit

Have you got a new CI? The Newsletter looks visually really good.

June news repost

Ok, it's amazing that the CCR1072 is still the biggest Hard, I'm a fan of Mikrotik, but in the ISP where I work, we are with a troughput of almost 20Gb, reaching almost saturate some 10Gb interfaces and with a CPU that peeks already 50% (it's a BGP core) and I have nothing to offer superador (I do not evaluate putting x86 and dealing with generic hard). They want to migrate brand and I still resist but I need new CCR !!!! Minimum of 10 SFP + and 2/4 SFPQ-QSFP28 equipment to have uplink between 40 and 100Gb. It would be a pity if they did not reach the market's needs in time, because the core once they are migrated is expensive to make changes.

I trust Mikrotik. I do not lose hope.

We are working on something for you as well. New extreme performance devices are in the works, as well as v7 BGP speed improvements are still on track.

These new 10Gbps switches look excellent! Though I'm also really interested in the new outdoor switches (CSS610-8P-2S+, CRS318-16P-2S+, CRS318-16Fi-2S), is there any prediction as to when they'll be released?

BGP will not work perfectly on CCR1072 because it can not make full use of its multi-core architecture. You should consider a virtual machine with CHR.
ROS v7 is supposed to solve this handicap but I really hope Mikrotik will put it out soon, it has being so long since they should have moved to v7.

The Ethernet tests are missing.

I don't think that is still on for v7. There will supposedly be improvements in the speed but apparently it is not feasible to make it multi-threaded.

I don't think that is still on for v7. There will supposedly be improvements in the speed but apparently it is not feasible to make it multi-threaded.

It is not technically possible to make it true multi-threaded due to the run-to-completion requirement of routing filters.

However it is possible to use a co-operative approach where you have a per-peer process with it's own RIB, filters are processed for that peer, then pushed to a central conductor process between all the peer processes. This is similar to how openbgpd handles it.
This means that the load is spread across the cores, but each peer will be processed on a single core at a time, and likewise the controller process runs on a single core at a time.

If you watch the video here: https://www.youtube.com/watch?v=NbfKplzda7I you can see that this is how the new routing engine in RouterOS v7 works.

Ok interesting that they got it improved... indeed, a thread per peer would seem to be possible at least for the processing of the peer session.
I think that would include the filters. The part that is to be single-threaded is the calculation of the active routes based on all received information.
Maybe even that could be split when the number of routes is huge and it can be separated e.g. by prefix length. But of course it would need to sort
and split the info, which may take more effort than it is worth.

+1 for outdoor switches availability prediction

Nothing new about MPLS hardware offload?

A 40G switch could have...

Surprisingly low price on the 40G stuff, gonna check the data later. Thanks)

Hi normis.

I found a Presentation https://mum.mikrotik.com/presentations/ ... 886866.pdf with the topic GPON.
Where could I get more information on the subject?

CCR-eOW-12x100G-36x25Gw
CCR-eOW-1x25Gw-2x10GC
CCR-eOW-1Gw-1G

Would I be stupid in assuming that these strings that I've found have something to do with the "New extreme performance devices"?

I wonder what CPU arch these new CCRs will use, should they exist...

New switches? So we might see improvements to SwOS?
*crosses fingers*

Hello Normis,

Does that mean QSFP288 (100GbE) support is in the works?

I'm guessing that's one of the big reasons v7 hasn't come out yet is to make sure BGP supports all cores instead of only running on a single core?

Daniel

Any timelines on this? We currently working on new network and looking at the 1072 and doesnt look like going to cut it as need to do PPP terminations. Between 20-50gbps and needs headroom to expand for us.

About the future CRS318-16P-2S+ will all the 16 ports have POE+ ?

Would pair of LHG XL 52 ac be decent replacement for pair of QRT2, for PtP ? Using QRT2s because of tree foliage, haven't tried 5GHz yet in those conditions.

5GHz is more prone to obstacles than 2.4GHz, it is already lucky that your link works behind foliage, usually it is a big problem for wireless links. Maybe some fresnel lines manages to establish the link but fresnel is also narrower in 5GHz.
Anyway, almost every situation is particular in wireless so if you can afford it might be worth a shot. I have had one situation where a 5km point to point had a hill in its line of sight, just the top of the hill, but it still managed to connect at 5GHz, obviously the upper fresnel zone was helping it.

Your comment about the fresnel zone solution with this antenna is very good.

In my opinion, the LGH XL 5ac is too specific for the case and considering the 60G will not be in demand (but in time we will see). This is probably useful in places where you do not have the choice of antenna placement. But it would be great if the manufacturer still provided the antenna design philosophy, the specific solutions, otherwise it's more like marketing.

An interest or dual band does not require a specific solution for the antenna grid distance from the transmitter to minimize interference in either band

The CRS326-24S+2Q+RM has my interest but have you considered making a 48 port version?

Also, include cSFP support. For those of you who do not know, it is possible to have 2 connections on each SFP module, without splitting the port speed. This would mean on a 48 port switch, you could make 96 connections.

For companies like us offering point to point FTTP connections, it would mean we could fit much more in our cabinets and connect 96 customers per 1U rack space.

It should still have 2 x 40Gbps module ports for uplink and I think at a price point of $999 (double the price of the 24 port version), you would sell a lot of these!

Please for the love of all that is holy make this product.

Also need an mdu crs back like the 8 port gige with two or four sfp+ ports in small form factor. When that was discontinued I cried.
