Skylight Application Notes

Ethernet Service OAM standards provide a framework to continuously monitor key SLA performance metrics at layer 2. These standards are designed to provide a uniform set of tests and resulting measurements that can be implemented directly in network ...

Overview Plug & Go enables you to quickly install a factory-reset Performance Element unit on the network and remotely manage it without requiring further unit configuration. The unit discovers and configures its own service ports, automatic...

# Overview Cisco Provider Connectivity Assurance Sensors support the use of the Network Time Protocol (NTP) to synchronize the unit’s local clock with an external time reference. When all sensors are synchronized to the same time reference, one-wa...

Overview Skylight performance elements support Service Availability (SA) to determine the number of unavailable seconds and other counts for a specific service. You can define Service Availability instances with one or more SA metrics (criteria)...

Overview Ethernet Ring Protection (ERP) is a protection mechanism that maintains high availability of Ethernet services for ring topology networks. ERP is based on the ITU-T G.8032 specification. An ERP ring consists of at least two units: one u...

This application note describes how to set up Y.1564 in your Skylight performance element network to perform end-to-end Ethernet service activation tests. The Accedian implementation of Y.1564 supports the following types of tests: Layer-2 two...

This article is intended to give the reader a complete description of how Accedian’s Skylight suite of products calculate the Mean Opinion Score (MOS), a general and widely-used metric, to state the quality for Voice over IP (VoIP). Skylight senso...

Accedian Networks has implemented a new feature on its network interface devices (NID) that provides the ability to create CLI scripts based on the unit’s configuration. This feature, called Generate Configuration Script, is available on all MetroNI...

Overview The advantage of the Virtual Synchronization method is that one Sender device may measure towards hundreds or thousands of Responders without needing to provide a common synchronization source between them. Compared to NTP or PTP, the l...

Overview Service providers that deploy Ethernet business services can face significant challenges in maintaining efficient bandwidth usage and per-application Quality of Service (QoS), since companies typically use several business-critical applic...
