Industry reports say that 60% of employees in large enterprises work from branch offices. They do so by accessing critical applications and services via their corporate WAN for vital business functions such as sales, finance, customer support etc., on a day-to-day basis. Their lives are so dependent on the WAN that any minor reduction in quality will lead to huge losses in productivity, and increase customer dissatisfaction.

Challenges of managing a WAN

The performance of a network is dependent on many components including few which are beyond the control of an organization such as the ISP's quality of service. You can't measure it and you can't take it for granted either. [Ever heard an ISP saying "sorry we found that our quality was below the agreed levels for the months 3 & 5 and hence we would like to refund you" without you asking for it?]. Moreover, with the increased collaboration, network pipes are now carrying voice and video which need higher QOS, the lack of which defeats the purpose.

Some of the common problems in delivering a high performance network are:

• Continuously visualize the expanding and complex network infrastructure and the service provider portion of the network

• Analyze terrabytes of data and convert them into meaningful trend charts for capacity planning

• Analyze the perennial and humongous log files and find out attacks, security threats before they impact the network

• Centralized monitoring of availability and health of a heterogeneous network infrastructure from disparate locations

• Backup configurations of every network device for ensuring business continuity

1 Motive Network Performance Management Suite

If you are a network manager, you need pro-active network performance management tools such as the ManageEngine Network Performance Mgmt Suite, that helps you do the following

•   Visualize the entire WAN as one single dynamic map

The web based map maker tool enables you to drag and drop routers and build a network map in a snap!



•   Identify potential performance bottlenecks first hand

Setting up thresholds based alerting on key parameters can foretell failures.

•   Get insights from the syslog

Sylogs provide an excellent way to learn more about device performance and failures. 1 Motive offers a clean way to get Syslog messages from multiple systems, correlate them, and provide unique data points that help in root cause analysis.



•   Troubleshoot slow links

IPSLA based monitoring enables you to see the hop-by-hop performance



•   Drill down right from a link to the different applications, protocols used and right down to the user who generates traffic. (Got You!)

Using NetFlow you can drill down a bad link right down to the user level.



•   Ensure business continuity by backing up router and switch configurations.

Losing sleep and resources to prevent accidental changes to device configurations? With 1 Motive you can automate backup processes across switches, routers, and firewalls. Rest assured! After all, if a network device does fail, you can restore it to the last known best configuration in seconds. And get reports on configuration differences and changes as well.
