MetroNID family

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.

  
Overview - Using NIDs to Create & Assure Ethernet Watch Video


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. We also offer a market-leading 10GbE solution, the MetroNODE 10GE™.

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.
  • Intelligent 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.
    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).
  • Switch-Free Aggregation
    Latency-free, multi-port aggregation from up to 4 ports to a single GbE, or from 2 GbE's to a single GbE or protected pair. De-aggregate by VLAN, or any combination of Layer 2 - 4 frame criteria.
  • Ring Support
    Blazing-fast RSTP ring connectivity (802.1w)

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 24 / 48 VDC 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.
