Razvoj poteka v sodelovanju s podjetji Amazon, Delta Electronics, Marvell, NVIDIA, Edgecore Networks in Wistron NeWeb (WNC). Projekt je bil prvotno ustanovljen s strani podjetja Amazon za opremljanje omre\u017ene opreme v njihovi infrastrukturi.

Vklju\u010duje gonilnike za interakcijo z indikatorji, senzorji temperature, ventilatorji, vodili I2C, GPIO in SFP-moduli, ki so uporabljeni v stikalu. Za upravljanje se lahko uporabljajo orodja IpRoute2 in ifupdown2 ter gNMI (gRPC Network Management Interface).
