Remote Office Visibility with Distributed Network Analysis

Organizations run on their networks. In nearly every industry, productivity depends on Internet access, email, file sharing, Web applications, and VoIP, not to mention business services and custom applications. Combine this with a widely distributed workforce and the accompanying widely distributed network infrastructure of most modern companies, and the challenges of real-time network management and troubleshooting seem overwhelming.

When networks become large and complex, spanning multiple locations and data centers, this real-time understanding can be achieved only with a distributed, intelligent network analysis solution that also includes your remote offices.

Join us on August 20th for a webinar to see how WildPackets is leading the charge on providing enhanced visibility across your entire network with a single, distributed, and cost-effective network analysis and troubleshooting solution.

Why Customers Choose WildPackets

Customers come to us for a multitude of reasons. Some aren’t happy with their current network monitoring solutions; others are experiencing network glitches that they cannot solve; and some simply need a cohesive analysis solution. WildPackets offers a suite of products that bring customers to us from far and wide, many of whom need specific capabilities in their monitoring solution. Let’s take a look at just a few of the reasons WildPackets is the leading network analysis solution.

10G Analysis
WildPackets led the way in 10G analysis, being the first to introduce a network recorder to break the 10G barrier. When our TimeLine network recorder was introduced in 2010 it was the only network recorder to capture and store packet-level data, with no data loss whatsoever, at 11.7Gbps. Since then, WildPackets has continued to refine TimeLine, offering even more real-time statistics, increasing our overall data throughput, and adding support to capture directly from 40G network segments.

Network Forensics
Going hand-in-hand with network recording is network forensics. As you’re streaming packets to the network recorder perhaps you see a troubling trend in the real-time dashboard, or maybe a user enters a trouble ticket. Network forensics allows you to analyze a subset of your recorded data while the overall high-speed capture continues uninterrupted.

Often associated with security, network forensics goes well beyond security and also helps solve far more common issues on your network, like spikes in utilization, drops in VoIP call quality, and increased latency in both network and application performance. If a problem does occur, you no longer have to try to recreate the problem, which is typically the most time consuming task in any troubleshooting session. Instead, with TimeLine, you simply go back in time, find the problem on the dashboard, and solve it.

Remote Analysis
The days of using a laptop to perform portable analysis, especially on high-speed wired networks, are now extinct. Corporate networks are highly distributed, even for small to medium sized businesses. Even if your company operates from a single location, odds are you host some services remotely, and use some level of software-as-a-service (SaaS), making it difficult to always be where problems are occurring. WildPackets’ Omni Distributed Analysis Platform provides a wide range of options for remote network analysis, from “lightweight” software solutions like OmniPeek Remote Assistant and OmniEngine software probe, to high performance network recording appliances like TimeLine. With a WildPackets solution, network engineers can monitor and analyze highly distributed network architectures without ever leaving their desks.

Top-Down Approach to Network Monitoring
For an overall, top-down view of any network segment, customers find WildPackets flagship OmniPeek network analyzer most helpful, whether as a portable analyzer or as a console to any of our remote analysis solutions. OmniPeek provides complete visibility into your network – including Ethernet, Gigabit, 10G, 802.11a/b/g/n/ac, and VoIP and video. OmniPeek provides visual context into the network so that even junior IT staff can drill down into performance problems and solve performance issues across multiple network segments. This ensures maximum network uptime and user satisfaction.

The Full Suite of Network Monitoring and Analysis Products
And for a complete view across your entire network, WildPackets offers WatchPoint network monitor. This solution builds on our suite of distributed analysis products and provides a comprehensive graphical interface of overall network performance, including top talkers, top applications, overall utilization, VoIP performance, and detailed reporting of detected network and application problems (Experts). WatchPoint also provides a direct link for detailed, packet-level analysis to determine the root cause of any issue.

Are Your Users Complaining? Pinpoint the Reason with OmniPeek

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.

Network Downtime
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.
