Our SONiC based AsterNOS can perfect run on our own hardware, in theory it can run on other vendor’s  hardware, there will be a problem on verify the compatibility,we can arrange a meeting call discuss specially. We strongly suggest you to use our own hardware, which supports the best software compatibility, tech support, hardware stability and of course very cost-effective price

Is there any license fee or software support fee that we need to pay for Asterfusion SONiC?

Usually our AsterNOS runs on our own hardware (for Teralynx ,Tofino and Marvell) we provide either bare metal hardware, or hardware with AsterNOS, there is some amount of software cost if you choose H/W and S/W bundle, but this bundle should be more cost effective than today’s White box and NOS from another vendor.

What is the difference SONiC and P4, and also tell us the difference of your NOS and those similar.

SONiC is used in most data center fabric as the basic OS, our software work on both Teralynx ,Tofino Marvell makes SONiC be able to run these switch chips smoothly, which is our value to help people who want to use innovated features on today’s new switch chip other than broadcom.
P4 is another approach for today’s network disaggregation, it has pretty good usability in niche markets like gateway, load balance or NPB, in these market when people also want to be part of cloud eco system, they need a way to combine P4 with SONiC, that’s what we are doing, we help people to implement these applications in SONiC way.

What is your SONiC software upgrade Service Support?

Asterfusion offers a perpetual software license, we will provide bug fixing and security patch all life long.For example, if you buy version 3.1 with the shipment, you will get all the upgrades 3.x  unless there would be an EOL of version 3.x  . Suppose we release 4.0 in the coming 1 year, you can also get free upgrade from 3.1 to 4.0, and get 4.x upgrades in free.
