Accedian Networks packet assurance demarcation units feature a unique hardware-based design that provides advanced performance testing and service creation capabilities in a compact, cost efficient, carrier-grade in-line element. All EtherNID ™ and MetroNID ™ demarc units are built on the patent-pending Fast-Thru ™ architecture.

Unlike store-and-forward architectures, the Fast-Thru’s silicon data-path provides wire-speed pass-through performance without adding jitter or delay, while at the same time providing microsecond measurement resolution and real-time processing of every packet flowing through the unit.
