[j-nsp] Big flows up to 320 Gbs

[Roger Wiklund]

Hardware wise I would go with at least QFX5110-48S, then you have
4x1000Gbps uplinks, but even better go with QFX5120-48Y for 8x100G uplinks.
Also, don't use VC or MC-LAG unless you really must. Instead use EVPN-VXLAN
to provide multihoming, L2 stretch, Anycasted default GW etc etc.

Roger
