Monitor network health in real-time


The IP SLA Module assists in monitoring and verifying network performance by automatic discovery of devices that transmit IP SLA and Real-time Performance Monitoring (RPM) data.

As networks grow larger in size and complexity, they can become challenging to manage. It can be difficult to verify the health of large networks, and administrators may not be able to analyze where problems are occurring. This can result in higher business service costs.

The IP SLA Module can assist administrators in monitoring and verifying network performance. This is achieved by automatic discovery of devices that transmit IP SLA and Real-time Performance Monitoring(RPM) data from Cisco IP SLA and Juniper RPM devices. The module then records the data transmitted from these devices and displays the information in real time.

Using the IP SLA Module, you can:

  • Utilize the power of a network analysis tool that monitors data from Cisco IP SLA and Juniper RPM devices, which can provide important data about network quality.
  • Analyze and troubleshoot network quality with with real-time monitoring and historical performance monitoring. This is accompanied by proactive alerts by e-mail, SMS and syslog notification to administrators when data levels are above or below predetermined threshold settings.
  • Enhanced convenience, ease-of-use and flexibility for engineers and help desk consultantsEnsure VoIP performance by monitoring Jitters, MOS, ICPIF, latency and packet loss, which helps administrators analyze voice delays or quality loss of voice in the network.

Key Features of the IP SLA Functionality


Using the IP SLA view, it is easy to monitor the network and summarize the network health. You can group network IP SLA links and edit the IP SLA group name.

The NNM–IP SLA module is also able to monitor response times, packet loss, latency and packet jitters. Advance monitoring parameter of the module include: schedule (Start –time, life, age out), elapsed time (frequency, time interval between packets), number of packets, payload size, UDP/TCP port number, ToS bit, and VRF (VPN Route Forwarding) to help you analyze application throughput and verify network delay problems.

The module can monitor and analyze web access problems via HTTP round-trip time testing to determine which hop is causing web access delays. The IP SLA can monitor reachability statistics, which shows the percentage of device capability within 24 hours, as well as the daily time spam, CPU heat chart and memory usage.

In addition, NNM-IP SLA can generate network performance reports automatically and can act according to predetermined thresholds, with the module issuing alerts via SMS, e-mail and syslog if the levels have been breached, while also sending alert reports.

VoIP Performance Monitoring

The NNM IP SLA Module is especially useful in leveraging the quality of VoIP service by monitoring specific VoIP Performance statistics including MOS, ICPIF, jitters, network latency and packet loss, which can provide important information about voice delays and the loss of voice quality.


The NNM-IP SLA can help administrators configure Cisco IP SLA devices more easily and conveniently via a webpage tool that allows for in-depth reviews before deployment. This helps to save time and cost, and reduces human error.

Operation support

With Cisco IP SLA and Juniper RPM, NNM-IP SLA can setup and test performance baselines for each operation, and is able to test multiple operations and schedule the operation testing. The module also allows administrators to calculate IP SLA results using an input formula rather than calculating each hop.

By using NNM-IP SLA, you will gain the ability to monitor network health in real time, which will help you raise the quality of your customer service, leading to greater client satisfaction.
