I used NetScout OptiView XG because I just happened to have access to two of them while writing this article.

software analyzers, I set up a lab and ran a couple tests. To demonstrate the different results you can get with hardware vs.

According to the WinPcap website, “WinPcap consists of a driver that extends the operating system to provide low-level network access, and a library that is used to easily access the low-level network layers.” Generally speaking, in a Windows environment, Wireshark uses WinPcap software and Microsoft’s NDIS to capture packets. I’ve seen many analysts assume that if they capture all the packets, then the delta times must be accurate. Inaccurate time stamps are the worst because you will probably be unaware when this happens.

The best-case scenario is that you drop packets because you might notice that and then figure out why it's happening or try a different tool. Both scenarios may result in lost packets or inaccurate time stamps. Then there are some of the wildcard issues like using USB Ethernet adapters without knowing what version they are or remotely capturing from an interface (i.e. Unfortunately this may not help since you need to understand quite a bit about your computer hardware, configuration and operating system behavior to get an accurate picture of hardware performance. Some people I have spoken to think that running the software analyzer on Linux or Apple is the answer. In addition, configuration issues may arise due to interference from endpoint security, firewalls and other CPU-intensive applications.

For example, if you install Wireshark on a Windows-based computer, it has to contend with other Windows services while capturing packets. Since the software-based analyzer wasn’t designed for a specific type of operating system or computer, be aware that it will have some limitations. This is due to the fact that all I need is the packets and addresses to determine application flow or dependency I don't need the timings. When I need to capture data and perform protocol analysis or application profiles, I’m comfortable using software analyzers on my laptop. If a trace file is too large, I use Wireshark’s editcap utility to break the large trace file into smaller ones.

Wireshark is user-friendly and I can run it on my laptop instead of lugging around a hardware analyzer. Many times, I use a hardware-based analyzer to capture packets and then use Wireshark software to analyze the data. When I need to perform network latency analysis or troubleshoot a performance-related issue that requires millisecond or lower accuracy, I reach for a hardware-based analyzer. Both types of analyzers have their place.

The general software-based tools are exactly that software you can download and install on various systems.

Hardware-based protocol analyzers are straightforward since they are specifically built to capture packets. For the purposes of this article, I will refer to two broad categories of network analyzers: dedicated hardware-based and general software-based tools Unfortunately not all protocol analyzers are created equally. Capturing packets for network analysis seems pretty straightforward: Install your favorite packet capture tool, hit start, stop and save your trace.
