Per packet load balancing

Is there a solution which can offer per-packet load balancing?

I have multiple sites which are identical, and utilise a private layer 2 ethernet private line network. An underlay and an overlay network exist; the underlay has 1Gbps capabilities, however the overlay can only support multiples of 100Mbps due to physical hardware bottlenecks between the overlay and underlay networks.

I'm after a solution which will be able to forward >100Mbps TCP traffic between sites. Everything I've found so far doesn't solve this issue as they seem to operate on a per-flow basis, which hashes to a particular 100Mbps link only.

Does this solution exist? Maybe SD-WAN for a 'tunnel' overlay for the.. overlay network?

Any gotchas to be made aware of?
