What is packet switching? Packet switching is a technique used in computer networks to transmit data as packets. Instead of reserving a dedicated communication channel for the entire duration of a transmission, packet switching breaks the data into packets and sends them independently. This method en...
Packets are sometimes defined by the protocol they are using. A packet with an IP header can be referred to as an "IP packet." An IP header contains important information about where a packet is from (its source IP address), where it is going (destination IP address), how large the pa...
Packet loss happens when packets of data are unable to reach their final destination. Learn the causes of packet loss and how to fix it.
Packet sniffing is a technique whereby packet data flowing across the network is detected and observed. Network administrators use packet sniffing tools to monitor and validate network traffic, while hackers my use similar tools for nefarious purposes.
What is packet sniffing? Packet sniffing is a method of detecting and assessing packet data sent over a network. It can be used by administrators for network monitoring and security. However, packet sniffing tools can also be used by hackers to spy or steal confidential data. The packet sniffi...
Packet loss is caused by several network anomalies. Most packet loss issues are temporary when the sender does not control the issue. For instance, an Internet Service Provider (ISP) may experience a malfunction in network equipment such as a critical router. This router failure may cause packet...
The process by which a networking or telecommunications device accepts a packet and switches it to a telecommunications device that will take it closer to its destination. Packet switching allows data to be sent over the telecommunications network in short bursts or “packets” that contain sequence...
What is packet capture used for? Importance of packet capture monitoring? Advantages of packet capture What is a PCAP file? What are the different versions of PCAP files? How do you capture packets? Why should IT teams use network packet capture tools? Packet Capture Definition Packet capture ...
What is packet sniffing? Packet sniffing is the practice of gathering, collecting, and logging some or all packets that pass through a computer network, regardless of how the packet is addressed. In this way, every packet, or a defined subset of packets, may be gathered for further analysis...
This is the most common cause of packet loss. Network congestion, as its name implies, is like congestion you would find on a highway. Cars on an eight-lane highway might be traveling at normal speeds, but during peak times, the number of cars on the same highway could triple, even ...
