ACCEDIAN MetroNID

High-Density Performance Assurance and Service Creation

Our high performance MetroNID® demarcation device provides carrier-grade demarcation within metro and access networks. Designed for cellular hubs, aggregation nodes, and CPEs, MetroNIDs segment, monitor and bridge diverse networks, delivering high-density OAM and performance monitoring visibility.MetroNID units help you to optimize and accelerate your services, protect your core network capacity, and deliver best-in-class QoS end-to-end. Whether they act as service creation device or as an SLA Assurance Demarcation, at gigabit Ethernet wire-speed, they illuminate dark-fibre networks with standards-based OAM, intelligent layer 1-4 loopback and in-service RFC-2544 performance testing – without adding delay or delay variation to customer traffic.”

Product Highlights

Proprietary Hardware Design

  • 1 μs measurement resolution
  • Ultra-low delay performance
  • Ideal for assuring real-time services

Service Assurance and Creation Features

  • Establish SLA-backed Ethernet services, point-to-point and multi-point
  • Enhanced fast and flexible service creation by shaping, policing, and mapping any VLAN IDs to the same EVC
  • 1-way delay and delay variation, throughput, packet loss, continuity and usage statistics

Ultra Low Latency Fast-PAAs™ Processor

Wire-Speed Performance

At the core of the MetroNID® 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, bandwidth profile enforcement and traffic conditioning on the highest capacity network links, the MetroNID effortlessly handles 100 flows in a full line-rate link with mere microsecond transit time.

Features

Service Assurance

  • End-to-End OAM Functionality
  • Intelligent, standards-based Operations, Administration and Management
  • Throughput SLA Meter™ Performance Monitoring
  • Monitor continuity and measure delay, delay variation, frame loss and availability, including 1-way performance validation with microsecond resolution
  • Intelligent Layer 1, 2, 3 and 4 Loopbacks
  • In-service Layer 1-2-3-4 loopbacks per-flow, defined by VLAN, Class of Service, 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 2-3 and4 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/EBS/CBS limits by filtering criteria or for 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
  • Wire-speed Traffic Filtering
  • Filtering of wire speed traffic at Layer 2-3 and-4 (per VLAN, Ethertype, Protocol type, MAC, IP, L2CP, BDPU, User Defined)
  • Switch-Free Aggregation
  • Delay-free, multi-port aggregation from up to 3 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, 3 and 4 frame criteria
