Segment, monitor, troubleshoot and bridge networks with high-performance, in-line MetroNID™ packet assurance demarcation units. Acting as a transparent, carrier-grade optical repeater at gigabit Ethernet wire-speed, MetroNID units illuminate dark-fiber networks with standards-based OAM, intelligent layer 1-4 loopback and in-service RFC-2544 performance testing – without adding jitter or latency to customer traffic.
Integrated service creation and traffic conditioning establishes Ethernet Virtual Circuits over multi-technology, multi-protocol and multi-vendor networks. Integrated zero-latency traffic shaping, filtering, bandwidth regulation and switch-free aggregation allow MetroNID units to outperform switches and routers many times their cost in edge applications.
Fully MEF and NEBS level 3 certification confirm the carrier-grade design proven by over 5,000 systems deployed in critical applications worldwide.
MetroNID units help you to optimize and accelerate your services, protect your core network capacity, and deliver best-in-class QoS end-to-end.
MetroNID models
With a comprehensive selection of models to choose from, there is an EtherNID™ or MetroNID unit that fits your particular application and network location.
ESAP Service Creation & Assurance Functionality
Service Assurance Functionality:
- PAA™ & SLA-Meter™
High-precision, hardware assisted, latency + jitter-free demarcation, monitoring and measurement of latency, jitter, frame loss and continuity, including 1-way performance validation with microsecond resolution.
Multi-flow, multi-service, multi-site performance assurance enables real-time SLA assurance over any network. Supports point-to-point, multipoint & mesh topologies, unicast & multicast testing.
- In-Service Throughput Testing
Verify the throughput of EVCs in-service, without affecting customer traffic. EtherNID™ & MetroNID™ units generate & analyze traffic flows up to full wire-speed at both layer 2 & 3.
- RFC-2544 Automated Test Suite & Reports
Advanced tool based on the RFC-2544 standard that can be used to measure and diagnose throughput, delay, jitter (delay variation), frame loss, and back to back efficiency.
- Inteligentni loopback
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.
Units respond to in-band loop-up commands from most third-party Ethernet test sets and monitoring systems, as well as via Y.1731 standards.
- Per-Flow Statistics
Real-time statistics of live traffic at layer 1-2-3-4 (per VLAN, Ethertype, ToS, CoS, MAC, IP, etc.).
- Tapping & Monitoring
Single or dual monitor ports providing filtered, real-time access to unidirectional or bidirectional traffic.
Service Creation & Traffic Conditioning
- Service Mapping
Create E-Line, E-LAN & E-Tree services directly at the demarc point - service mapping applies C/V-LAN tags (selective push) and/or configurable service class to traffic meeting detailed layer 2,3 & 4 criteria.
- Bandwidth Policing
Limit upstream and downstream CIR/EIR by filtering criteria or for all traffic. Facilitates Carrier Ethernet service provisioning and on-demand/incremental service upgrades. Allows commissioning of MEF-compliant services.
- Zero-latency Traffic Shaping
Pre-conditioning of traffic to accelerate services and optimize access link bandwidth use. Passes highest-priority traffic Fast-Thru™ without added delay or jitter while other traffic is buffered until capacity is available.
- Wirespeed Filtering
Filter wirespeed traffic at layer 1-2-3-4 (L2CP, BDPU, per VLAN, Ethertype, Protocol type, MAC, IP, User Defined).
- 4-to-1 Multi-Port Aggregation
Latency-free, multi-port aggregation from 4 Fast Ethernet ports to a single GbE, or from 2 GbE's to a single GbE or protected pair (total traffic < 1 GbE). De-aggregate by VLAN, or any combination of Layer 2 - 4 frame criteria.
General Functionality:
- Jumbo Frames support
All functions supports Jumbo Frames up to 10,240 bytes at all rates (10/100/1000 Mbps).
- 3-Way Redundant Power
Units can be powered using 5VDC, or dual -48V feeds, all mutually redundant.
- Plug & Go™
Full automated customer-level install, auto-configuration & inventory tracking capabilities.
- SNMP v1 & v2c:
Support SNMP v1 and v2c for monitoring, alarms, OSS integration and unit configuration.
