The V-NID performance assurance suite provides a comprehensive solution for verifying networks on a granular and continuous basis, and validating SLA conformance. By utilising standard reflectors such as ETH-OAM or TWAMP integrated into the network components in combination with Accedian's patented measurement technique the V-NID product suite enables one-way monitoring of network performance with high accuracy, without the need for hardware test points at each end of connection.
Optionally, endpoints equipped with the V-NID Standards+ software reflector offers you an even larger set of high accuracy one-way metrics as well as the option to disguise your measurements to look like any other end-user frame on the network such as VoIP flows, SCTP signals or HTTP streams.

  • Standards-based one-way network performance assurance solution using ETH-OAM, TWAMP and Accedian Standards+
  • Standards+ supports extended measurement types for even greater performance visibility
  • Patented, high-accuracy one-way delay measurement technique without need for synchronised hardware test points at each end of connection
  • Centralised or distributed measurement injection using the V-NID Actuator
  • Centralised provisioning, management, mediation and reporting via the V-NID Manager
  • IPv4 and IPv6 dual stack for both management and RFC5357 TWAMP measurement
  • IP, Ethernet and OAM end-user experience metrics summarised and displayed via VisionMETRIX™ performance monitoring dashboard
  • V-NID Actuator - the active performance measurement component in the V-NID performance management architecture.
  • Performance Monitoring (PM) Reflector - An Accedian or 3rd party, standards based responder of measurement frames sent from a V-NID ACTUATOR
  • V-NID Manager - the main controller unit in the V-NID application performance and SLA monitoring suite.
  • VisionMETRIX - Accedian's performance visualisation portal delivering actionable and concise dashboards of network performance

V-NID Actuator

  • TWAMP Sessions - Support for Two-Way Active Measurement Protocol (TWAMP) sessions as specified in RFC-5357.
  • IPv4 and IPv6 dual stack for both management and TWAMP measurements
  • Ethernet OAM Sessions - Support for ITU-T Y.1731 (and IEEE 802.1ag) sessions. Ethernet Loopback (ETH-LB), Two-way Frame Delay Measurement (ETH-DM) and Vendor Specific OAM PDU (ETH-VSP) implementing a layer-2 version of 2xOneWay.

Performance Monitoring (PM) Reflector

  • ICMP and UDP echo
  • TWAMP TWO-WAY Active Measurement Protocol as specified in RFC-5357
