V-NID Suite Overview

Standards-Based, One-Way and Two-Way Network Performance Assurance & SLA Monitoring

Accedian Networks has leveraged its industry-leading Layer-3 TWAMP and Layer-2 ETH-OAM based performance assurance technology to introduce the V-NID™ product suite. By using and extending the existing standards for perfor­mance assurance, V-NID™ offers a unique solution to provide detailed one-way network KPI’s and SLA monitoring without the need for external synchronization.

End-to-end SLA Monitoring
Verify, Validate, Visualize

The V-NID performance assurance suite provides a comprehensive solution for verifying networks on a granular and continuous basis, and validating SLA conformance. By utilizing 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.

End-to-end SLA Monitoring
