Network Traffic Shaping: What It Is and How It Works


Have you ever experienced slow internet speeds or buffering while streaming videos or downloading files? Network traffic shaping might be the solution to your problem.
Network traffic shaping, also known as packet shaping, is a technique used by ISPs and network administrators to control the flow of network traffic. It involves prioritizing certain types of data over others to ensure the best possible user experience.
But how does it work? Network traffic shaping involves monitoring the amount of bandwidth being used at any given time and then prioritizing certain types of data. For example, streaming video or voice over IP (VoIP) traffic might be given higher priority than file downloads or email traffic.
Network traffic shaping can also be used to prevent network congestion. During peak usage hours, such as during business hours or major sporting events, network traffic shaping can limit the amount of bandwidth used by certain types of data to prevent the network from becoming overloaded.
While some may argue that network traffic shaping is a form of internet censorship, the technique is actually designed to improve the overall user experience. By prioritizing certain types of traffic, network traffic shaping can help ensure that users are able to access the content and services that they need without experiencing slow speeds or interruptions.
In conclusion, network traffic shaping is an effective tool for network administrators and ISPs to improve the performance of their networks. By prioritizing certain types of traffic and preventing network congestion, network traffic shaping can help ensure that users are able to access the content and services that they need quickly and reliably.

Network traffic sniffing


If you're a tech enthusiast, you've likely stumbled upon the term network traffic sniffing. But what the hell does it mean? Are computer geeks indeed up to something fishy? Let's find out.

Network traffic sniffing is the process of intercepting and examining network traffic passing through a computer network. We can say it's an advanced way of eavesdropping on conversations between different connected devices. By doing this, network traffic sniffing software or hardware can obtain sensitive information like login credentials, financial records, and other sensitive data.


Why would someone want to sniff Network Traffic?


People sniff network traffic because it helps them understand how a network works. For instance, a network administrator would want to know what is passing through the network to identify any loopholes or rogue devices. Besides, companies use network traffic sniffing to monitor incoming and outgoing traffic to identify any irregularities, such as data leaks or cyber threats.


Tools for Network Traffic Sniffing



  • Wireshark: This is one of the most popular network traffic sniffing tools, which can monitor data in real-time or obtain packet captures for future analysis.

  • Tcpdump: This tool is used for command-line packet sniffing on Linux, macOS, and Windows operating systems.

  • P0f: Detects the remote system details such as operating system, applications as well as IP fingerprinting techniques.


Is Network Traffic Sniffing legal?


While network traffic sniffing is legal, it can be illegal if done without the network owner's consent. It's essential to seek permission before you start sniffing any network to avoid criminal charges.
