Managing Internet & WAN for universities
Monitor key university services like elearning
Elearning is a key technology for universities today. Access for on-site and remote students is a service that needs to run as smoothly as possible. It is crucial therefore to detect any problems with these services such as delays and bandwidth saturation.
In this example we can see that elearning has large delays (round trip times or RTT). Anything higher than 200ms may result in complaints from students.
Protecting elearning with Quality of Service (QoS)
Implementing QoS (packet shaping) rules is a quick way to reduce the latency that students are experiencing. In the example below we have implemented traffic shaping on elearning and decreased the delays. You can read more about QoS here.
Notice the delays are greatly reduced, highest noted delay is 100ms down from 500ms above.
Controlling access and monitoring users with Active Directory support
Through NetScope's Active Directory Support Internet access can be restricted to individuals and groups. For example you can keep academic Internet use unrestricted while limiting on-site undergraduate access. Within NetScope you may click on any segment and drill-down to see the top users and their activity.
Block Unauthorized Internet Activity - Apps and Users
Detecting some applications can be difficult with IP and Domain name filtering only. Deep packet inspection allows detection of applications like The Onion Router (The Dark Web / Deep Web) and BitTorrent. Universities are particularly susceptible to the misuse of their Internet by unauthorized apps due to the large base of users.
What is this pie chart showing?
The Activity chart shows all applications bandwidth activity for the selected time period. Each application's traffic is shown as a part of the whole. Within NetScope you can click on any segment in the pie chart to drill-down and see details such as users, bandwidth used and speed.
Block or alert on unwanted applications
Once an unwanted application type is detected with NetScope's deep packet inspection you can choose what you'd like to do with that traffic. Two sensible options are to block the traffic entirely, or set up alerts that will email the network administrator every time that traffic type appears. With the second option it enables the network administrator to alert the user that this is unacceptable behavior.
