Udviklingen udf\u00f8res i samarbejde med virksomheder som Amazon, Delta Electronics, Marvell, NVIDIA, Edgecore Networks og Wistron NeWeb (WNC). Projektet blev oprindeligt startet af Amazon for at udstyre netv\u00e6rksudstyr i sin infrastruktur.

ONL er udviklet af Open Compute-projektet og fungerer som en platform til at skabe specialiserede netv\u00e6rksenheder, der underst\u00f8tter installation p\u00e5 over hundrede forskellige switchmodeller. Det omfatter drivere til interaktion med indbyggede indikatorer i switches, temperaturf\u00f8lere, bl\u00e6sere, I2C-bus, GPIO og SFP-transceivere. Til styring kan v\u00e6rkt\u00f8jer som IpRoute2 og ifupdown2 samt gNMI (gRPC Network Management Interface) anvendes. Til at definere konfigurationer bruges YANG-datamodeller (Yet Another Next Generation, RFC-6020).             <\/p>\n<p>Systemet er tilg\u00e6ngeligt for switches baseret p\u00e5 ASIC Marvell og Mellanox, med op til 48 10-gigabit porte.
