Try as you might, making users happy with network performance is a difficult task. Sometimes problems arise with applications and sometimes with the network itself. Either way, it is your job to make the end user experience the best that it can be.
Luckily, if you are using OmniPeek, problems of any type, whether application or network, or common or rare, can be easily remedied. Let’s take a look at some common user experience issues and how OmniPeek can help to identify the root cause and guide you towards a permanent solution.
Fortunately unplanned network downtime is a pretty rare occurrence nowadays, but if it does occur the response must be instantaneous. With OmniPeek you can immediately assess the scope of the outage, from a few specific users to an entire subnet. If distributed, 24×7 analysis is in place, you can rewind the network to see exactly what was going on when the outage occurred, providing the best clues possible for determining the root cause, which in this case is probably equipment failure somewhere in the network path of the effected users.
Not Enough Bandwidth? Find the Hog
Bandwidth issues typically arise not because of a lack of bandwidth, but because a user or users are consuming an abnormally high amount of bandwidth. This is becoming more common with the wide availability of video streaming sources, particularly those that are not work related. The Compass dashboard in OmniPeek is an easy way to isolate bandwidth hogs, allowing you to identify not only the user but the type of traffic, providing the ammunition you need to ensure that network traffic is strictly business related.
VoIP Quality Issues
VoIP is the most commonly used real-time protocol on corporate networks. Given its real-time nature, it is extremely sensitive to network problems like too much latency, dropped packets, and jitter, much more so than “regular” network traffic. For real-time data to be useful, it must arrive in order, and within a few hundred milliseconds of being sent, otherwise it is no longer “real-time” and doesn’t fit into the overall conversational flow. Problems with real-time data will continue to grow as more corporate video is transmitted over IP networks, and as more wireless networks are used for the last 100m of data delivery (voice over Wi-Fi, or VoFi).
From a network perspective, VoIP, VoFi, or video over IP are just data on the network. In order to identify problems with real-time traffic, you first need to isolate the traffic, while still seeing it in the context of the overall network. To do this, you can use the Voice and Video dashboard in OmniPeek to see how real-time traffic is coexisting with the rest of the network. Then, the Calls and Media views will allow you to see a more detailed analysis of the packet-by-packet performance of the real-time flow, including detailed analytical metrics and a bounce diagram so you can pinpoint exactly where the problem is, and compare it with network activity to correlate real-time transport problems with overall network usage.
