Software network packet sniffers change the configuration of your network to “promiscuous mode,” so all network packets go up the stack. Software: Most traffic sniffers on the market fall under this category.This method also ensures no packets are lost or filtered out. Hardware: Hardware packet sniffers are plugged directly into a network, which is useful if you want to analyze a specific part of a network rather than the whole thing.There are two different kinds of network packet sniffers-hardware and software: Packet sniffing software takes the data gleaned from packet sniffing and transforms it into actionable data administrators can use to improve network performance. This can include metadata (for quickly identifying spikes in traffic or overall traffic patterns) or internal packet information. Packet sniffing is the process of capturing the packets moving through the network at any given time (regardless of how they’re addressed) and analyzing those packets for information useful for troubleshooting or network monitoring purposes. The packet is then reassembled in its original form and the transmission process is complete. After the packets get where they’re supposed to go, the data used to route the packet through its host network is dropped and it must pick up more routing data from the receiving network’s protocol stack. The four phases are application protocol, transmission control protocol (TCP), internet protocol (IP), and hardware.ĭata packets must pick up a port number and an IP address in the middle two phases before they can be transmitted over the internet, which happens during the final “hardware” phase. When packets travel through a network, they inherently travel through four phases of the protocol stack called Transmission Control Protocol/Internet Protocol. Everything you do on a network must be broken down into thousands of tiny chunks of data called packets. To truly understand the role network packet sniffers play in network performance best practices, you must know the basics of internet routing and packet sniffing. The first part is the network adapter connecting the sniffer to the network, and the second part is the sniffer software facilitating the gathering and analysis of data gathered by the traffic sniffer. This makes it easier for administrators to break down network traffic and pinpoint exactly what needs fixing instead of individually hunting through thousands of applications on your network.Īll traffic sniffers are comprised of two parts.
