Hello, I'm looking to shaker capabilities and I'm wondering if this kind of accomodation (see attachment also) can be achieved Ascii (flat) version : CN1 (2n VMs) <- n flows -> CN2 (2n VMs) CN1 (2n VMs) <- n flows -> CN3 (2n VMs) CN2 (2n VMs) <- n flows -> CN3 (2n VMs) In this situation concurrency could be mapped to the number of simultaneous flows in use per link.
