MetroNID-GPS

Product Overview

Accedian Networks’ High Performance Service Assurance™ platform the EtherNID® and
MetroNID® demarcation units, define the boundaries of the network, enabling end-to-end
service provisioning and assurance with carrier-grade performance.
The EtherNID and MetroNID units are based on Accedian’s wire-speed Fast-PAAs™ chip,
a unique hardware-based engine that provides advanced performance testing and service
creation capabilities in a low delay, carrier-grade, in-line hybrid test and network element
for compact and cost-efficient deployment at the boundaries of the network.
Unlike store-and-forward architectures, Fast-PAAs’ proprietary silicon design provides
wire-speed pass-through performance without adding delay or delay variation, while at
the same time providing microsecond measurement resolution and real-time processing
for every packet flowing through the unit.

Specifications
Service Assurance Features
• Loopback Functionality
– Layer 1, Layer 2 (MAC Swap), Layer 3 (IP Swap), Layer 4 (TCP/UDP Port Swap).
– Automatically reacts to in-band loopback requests sent from popular 3rd party Ethernet test-sets, as well as 802.3ah / Y.1731 OAM loopback commands.
– Loopback on specific VLANs, source/destination MAC/IP address(es), Ethertype,
protocol type, service class, or any logical combination.
– Loopback on specific MAC/IP source and/or destination address.
• Thru-Traffic Per-flow statistics
– Stats per VLAN, Ethertype, ToS, CoS, MAC, IP, etc.
– Stores up to 7 days of local and remote historical packet statistics in user configurable
history buckets (typically set from 1-15 minutes).
– Monitor up to 60 concurrent flows on MetroNID TE-R and TE-RS, 16 flows on other
units
