A MetroNID® hardware option, MetroNID® GPS is designed to assure real-time services with an embedded GPS receiver that provides highly accurate clock synchronization for 1-way measurements of delay and delay variation of Ethernet links with guaranteed 1 microsecond precision. Purpose-built with a high performance hardware design, MetroNID GPS works with both indoor and outdoor antennas, tracks up to 12 satellites, and raises alarms if the GPS signal is lost. This MetroNID synchronization option is ideally-suited for mobile backhaul networks where your competitive edge is tied into the accuracy of your network performance measurements.
Ultra Low Latency Fast-PAAs™ Processor
Wire-Speed Performance
At the core of the MetroNID® GPS is Accedian's unique Fast-PAAs™ hardware-based processor which enables the unit to provide microsecond measurement resolution for one-way delay and delay variation, and monitor up to 100 flows or SLAs – all while traffic flows transparently through the unit.
The Fast-PAAs silicon core architecture eliminates the delay of store-and-forward processing of Ethernet switches and routers providing the lowest delay solution available today. With quality of service (QoS) marking, enforcement and traffic conditioning on the highest capacity network links, the MetroNID GPS effortlessly handles 100 flows in a full line-rate link with mere microsecond transit time.

monitor and measure delay, delay variation, frame loss and continuity, including 1-way performance validation with microsecond resolution.
-
Intelligent Layer 1-4 Loopbacks
In-service layer 1-2-3-4 loopbacks per-flow, defined by VLAN, Service-Level, MAC / IP addresses or any combination of layer 2-4 header criteria.
-
In-Service Throughput Testing
Verification of EVCs in-service without affecting customer traffic, traffic flow generation and analysis up to full wire-speed at both layer 2 and 3.
-
RFC-2544 Automated Test Suite & Reports
Throughput measurement and diagnosis, delay, delay variation, frame loss, advanced test suite based on the RFC-2544 standard.
-
Per-Flow Statistics
Real-time statistics of any layer 1-2-3-4 flow (VLAN, ToS, CoS, MAC, IP, TCP/UDP).
-
Tapping & Monitoring
Single or dual monitor ports, filtered, real-time access to unidirectional or bidirectional traffic.
Service Creation & Traffic Conditioning
-
Ethernet Service Mapping
E-Line, E-LAN and E-Tree service creation directly at the demarcation point, fast and flexible VLAN to EVC mapping enables mapping an arbitrary set of VLANs to the same EVC.
-
Bandwidth Policing
Upstream and downstream CIR/EIR limits by filtering criteria or all traffic, facilitates Carrier Ethernet service provisioning and on-demand/incremental service upgrades.
-
Zero-Delay Traffic Shaping
Pre-conditioning accelerates services and optimizes access link bandwidth use, Fast-PAAs passes highest-priority traffic without added delay or delay variation, other traffic buffered until capacity is available
