Do you know what the differences are? Most of time, real-time and postmortem analysis shares the same template to analyze the traffic data. Real-time traffic analysis shows dynamic trends of the entire network, while postmortem traffic analysis shows exactly what has happened in this network. In this article, you will read the main differences between real-time traffic analysis and packet analysis in AthTek NetWalk.


1. Overview.
In Overview section, real-time traffic shows current bandwidth usage and accumulated traffic data. But if you opened a captured packet in AthTek NetWalk, you will see fixed values of the network traffic and these values tell you exactly what has happened during the capturing period.
overview vs

2. Packets.
When you opened a captured file in AthTek NetWalk, you will see a new tab named “Packets” created on left. Real-time traffic analysis doesn’t support Packets tab. In Packets tab, network administrators can read all the communication details including requested IP addresses, ports, protocol, etc. If a common packet analyzer enables network administrator to see a naked data, AthTek NetWalk enables users to see a reliable anatomical traffic data through detail and hex view tool.

3. Layered View.
There are 3 layers in Layered View section: Application, Net&Transport and Physical. A significant different is, you can see communication flows in postmortem packet analysis.
layered-view-vs

4. Events Tab.
In Events tab, network administrator can jump to the communication flow when it is a postmortem packet analysis.

5. Matrix Map.
In Matrix Map, real-time analysis only marks active connections in green, while postmortem analysis marks all successful connections in green.

In short, postmortem analysis enables network administrators to see all communication details happened on the network. All you need to do is to capture packets and open the captured file in AthTek NetWalk.

It contains settings for low-level operating system components and for applications running on the platform that have opted to use the registry. The kernel, device drivers, services, SAM, user interface and third party applications can all make use of the registry. The registry also provides a means to access counters for profiling system performance. The Windows Registry has a structure similar to Windows folders and files. Each main folder is named as a Hive. Do you know what does each hive mean? In this article, you will read the general introduction to Windows registry hives.

 COM (Component Object Model) is Microsoft’s component software architecture developed primarily for Windows. It is the foundation upon which OLE and ActiveX are based, and provides a means to re-use code without requiring re-compilation. In COM, a component is a platform-specific binary file that compliant applications and other components can utilize. Programs incorporating a component’s services never have access to its internal data structure, but instead include pointers to its standardized interface. Thus, it is possible for components to interact with each other regardless of how they work or what language they are written in. ActiveX, OLE/COM produces many registry problems on Windows system.

Application Paths are used for storing keys and values of Windows applications. If some application ceases to work on your Windows, you can clean and optimize this registry hive to fix the application problem.

Empty Registry keys are when a program of software has made a ‘folder’ and either never filled it with contents or has been uninstalled and the ‘folder’ remains but has no contents. They are harmless. Just take up a little space. It might also slow down certain processes if there are too many empty and useless keys. No matter what registry cleanup tool you are using, empty registry keys will certainly be removed in registry cleaning.

You can just enjoy it. We call that “inspiration”. Now can you remember what the music sounds like? What instruments have been used, piano, guitar or strings? In my experience, piano can produce pure and cool effects in nature. Let’s take piano as the instrument to create cool music on computer. Piano Music Let’s open AthTek DigiBand and select [make an accompaniment] to start. There are 6 options listed on the start screen. [make an accompaniment] will help you to create a pure accompaniment automatically. A pure accompaniment will cater to your hot heart (as main vocal) and cool it down. Generally, sadness, peaceful, memory, loneliness, silence and clean can produce cool effects in music creation. Let’s choose peaceful as the musical emotion in AthTek DigiBand. Usually cool music has a slow beat and BMP (beat per minute), let’s choose 4/4 beat and 80 BMP in this case. You can also choose a new music structure if needed. After these configurations, please press [Auto composition] button to generate the music. Auto accompaniment In the editing screen, please delete any other instruments except for piano, and then it will produce pure piano music as we need. Listen to the music you have just created. If you are not satisfied with it, you can click the refresh button at the beginning of track to change it. If it was cool music you want, you can now export it as .wav or .mid file. music editing Now you have already got the cool music for the hot summer.
