OpenWrt for 25Gbit Internet possible?

[Mijzelf]

@dlakelan

Look 25Gbps is crazy fast internet. This starts to get into the category where you need dedicated router ASICs etc. General purpose computers should be ok up to about 10Gbps. But think about it this way, at 10Gbps you can process 10e9/1500/8 = 833k packets per second. At 1Ghz that's about 1200 clock cycles per packet. Which is around 1 clock cycle per byte.

You must be making a miscalculation. 25Gbit/sec on 1GHz is 25 bits/clock is ~3 byte/clock.

Worked. Just bootet the box. But no connection.
How to configure the interfaces?

@cryoplay

How to configure the interfaces?

/etc/config/network

[cryoplay]

Im in but can i test if the interfaces are up and runnig ( Intel nic xxv710)?

LAN appears setup as eth0 into br-lan - is that one of your Intel NICs?

If so, just set up the others. Can you get an IP and connect to 192.168.1.1 via a web browser plugging into eth0?

If so, then browse to the network config in the web GUI and proceed.

Did you run ifconfig?

[cryoplay]

Sorry.

Screens are pictured from the phone.

I dont get an IP in the Lan.

I can run ifconfig.
Sorry for the pic.....

@cryoplay

I dont get an IP in the Lan.

I can run ifconfig.

Did you install both iavf and i40e?

Nothing will happen with an eth port unless it is referenced somewhere in /etc/config/network to start it up. So go ahead and define a wan interface around eth1:

config interface 'wan'
    option device 'eth1'
    option proto 'dhcp'

Run ip link show to see which one comes up when only one cable or transceiver is plugged in (ifconfig is deprecated). You may need to swap the port numbers to get wan on the correct one.

and since you may not even have eth0, the drivers may not all be there. Review the boot log (dmesg | more or dmesg | grep eth to see if anything started.)

[cryoplay]

Let me check....

kmod-i40e wasnt in the package.
Made a new one and reboot.

Now all drivers are in and i made the config.
No changes.

With the dmesg command im struggling because i cannot stop or search the List

[cryoplay]

Theres no eth0 but the drivers loaded.
Found the fault.
Mounted a Intel 810 Da2

Exchanged it with the 710

25Gbit/sec

I was doing 10Gbps which is kind of reasonable to expect a CPU to handle. That works out to 1200 cycles/packet and they're around 1500 bytes max. Yes if you multiply speed again by 2.5 you get your numbers.

In the end the point is just copying packets is a huge fraction of the full CPU/memory bandwidth at these speeds. That's why crazy fast 400Gbps core router will cost $300k or whatever and have custom ASICS that handle the packets.

[cryoplay]

Now both Ports are online.
But i cannot reach the web interface....

IP assigned successfully....

@cryoplay

But i cannot reach the web interface....

• Did you use the Firmware Selector?
• If so, did you install the luci or luci-ssl package for the web GUI?

[cryoplay]

No. Thought that would be standard. Can it be installed on the Box?
Because the internet connection is now up.

[lleachii]

@cryoplay

Can it be installed on the Box?

Yep:

opkg update
opkg install luci-ssl

@cryoplay

the internet connection is now up

(This can be found on the Wiki - it seems you're good to go now.)

[M10]

Add irq-ballance by the way.

[cryoplay]

Found it and installed it.

Thank you guys.
I post some benchmsrks if you want as soon i set up.

Irq balance?

Where?

[frollic]

It's another package

[cryoplay]

Found and installed.

Just runned iperf3 to my isp....
