Does this work across different regions on the cloud?

[0xbentang]

I'm using AWS and trying to test machnet for different AWS regions

When I try to run the hello world example, on the sender side I always got

ERROR: Failed to dequeue response from control queue.
machnet_connect() failed

Then I tried to create another VM in the same region, and the hello world works. This suggested something is wrong when it's cross regions?

I then also tried to build DPDK and run dpdk-testpmd on both end, and it shows it's receiving. The caveat is that for --eth-peer I need to specify the gateway MAC instead of the NIC MAC. I don't see similar setting in machnet, can you advise if this is indeed the issue and any potential fixes? Thanks in advance!

Hi @0xbentang,

Thanks for opening this issue. I can confirm that machnet doesn't currently support connecting to a remote peer when traffic needs to be routed to a different subnet via a gateway; machnet currently does ARP resolution for hosts in the same subnet. The changes should be straight forward but the current implementation just doesn't support this.

Best,
Ilias

Hi @marinosi,

Thanks for the quick reply! Good to know that it's currently not supported. Do you have an idea on when this will be implemented?

If possible I can also try to help on implementing it if it's straightforward. I'm more on Rust though and less experienced in C++, it will be very helpful if you can provide more context/guidance roughly on how you'd expect it to be done, thanks in advance!

@0xbentang, I am happy to sit with you sometime later this week to give some context so you can start.

Sure @sarsanaee what's the best way to communicate this?
