Visual Network Quality Management Solution

The increasing use of multimedia services such as voice, video and desktop conferencing requires enterprises to manage network service quality carefully. Enterprise IT departments urgently need unified standards and solutions to ensure network performance and quality. As a unified standard to define service levels, Service Level Agreements (SLAs) have been adopted by many enterprises to facilitate internal services. The IT departments in many large enterprises develop a set of SLAs to manage services provided to ''customers'' (primarily users of other departments inside the enterprise). The IT departments sometimes use these SLAs to compare their services with those provided by external network providers.
Because network requirements vary with industry type, enterprise size, region, and organizational structure, many networking technologies and modes must coexist. Furthermore, different services have different requirements for quality metrics. For example, voice services are sensitive to packet loss, while video services have more sensitivity to latency, and data services have high requirements for bandwidth. These varying network and service requirements lead to a complex SLA index system with dozens of indicators. Therefore, enterprise IT departments must consider how to monitor and manage SLAs effectively. The visual network quality management solution provides an SLA management component that supports end-to-end SLA design.


The visual network quality management solution helps enterprises identify key service types that must be monitored (SLA service management), monitor SLA tasks based on service types (SLA task management), and troubleshoot and optimize daily SLA monitoring.


Identify key service types that must be monitored (SLA service management)

Enterprise users can select service types that must be monitored based on the enterprise's business characteristics. For example, users can select voice, video, data, and web page browsing services. In eSight, these different service types are managed by different SLA collection types, indicator thresholds and indicator weights. For example, voice services have UDPJitter as the default collection type and adopt suitable thresholds and weights for latency, packet loss and jitter indicators by default.


eSight's SLA service management provides the following features:


  • Supports more than 20 predefined service types.
  • Allows users to customize service types based on requirements.
  • Enables users to adjust indicator thresholds and weights for services.
  • Allows users to adjust compliance thresholds for services.

Monitor SLA tasks based on service types (SLA task management)

After identifying service types that must be monitored, users can select related equipment, create SLA tasks, and monitor key network links in real time. During routine monitoring, users can instantly see Top N tasks that fail to meet quality requirements by paying attention only to daily compliance. Then users can adopt troubleshooting or optimization measures to address the problem.


eSight's SLA task management provides the following features:


  • Allows users to create, copy, delete, start and stop an SLA task.
  • Enables users to query historical data, alarms, and diagnosis information.
  • Clearly identifies Top N tasks that fail to meet quality requirements.

Troubleshoot and optimize daily SLA monitoring

After identifying a Top N task that fails to meet quality standards, users can take advantage of eSight's follow-up operations that help diagnose and fix the problem These follow-up operations include checking the SLA historical data, managing SLA reports, performing fast diagnosis, and adjusting configurations.


Checking the SLA historical data

Consulting historical performance data can help maintenance engineers understand the scope of a problem. SLA tasks are regularly performed to check the quality and performance of various services on the network. The system displays this quality and performance data in convenient charts that help quantify network quality.


Managing SLA reports

In addition to helping with immediate problem diagnosis and correction, eSight provides SLA reports that contain abundant statistics about service quality and other useful data. These reports provide accurate references for decision makers.


Performing SLA fast diagnosis

SLA fast diagnosis helps users quickly locate network faults. It allows users to check service quality of certain equipment without specifying service or task conditions.


Adjusting configurations

After identifying the root causes of network faults or quality problems, users can work with eSight's smart configuration tool to adjust devices in batches or change the way the devices interact on the network. After the configuration adjustment, it helps verify that the network quality has improved.


Summary

The visual network quality management solution simplifies SLA management by helping users monitor quality variables and diagnose and resolve problems as they arise.
