As a result, session traffic exhibits a sawtooth pattern and is bursty. TCP always expects the data in the send window to be sent out as soon as possible. Therefore, after the TCP packet arrival acknowledgment (ACK) arrives, TCP continues to send data by using the sliding window mechanis...

Common reasons for retransmissions includenetwork congestion where packets are dropped(either a TCP segment is lost on its way to the destination, or the associated ACK is lost on the way back to the sender), tight router QoS rules that give preferential treatment to certain protocols, and TCP ...
This is a quick discussion, all puns intended, about why QUIC is important to the modern internet.
The most widely used network protocol analyzer in the world, Wireshark, has released version 4.0.8. It is employed for network analysis, troubleshooting, software and communications protocol development, and education.
Wireshark –Wireshark is a free and open-source packet analyzer. Very widely used, this tool is often used by attackers when they have successfully entered a network for “sniffing” the traffic. Wireshark’s ability to capture real time packets, convert them to human readable form and a ve...
(in/out). They can then be inspected either locally or copied to external storage in a .pcap format, which is the default format for Wireshark captures. So you can then use your super-duper tool to inspect them and find that little ping packet that proves it wasn't the network in ...
It works by sending a SYN packet in an attempt to open a connection. A SYN/ACK response indicates an open TCP port, whereas an RST response indicates a closed port. If no response is received or if an Internet Control Message Protocol (ICMP) unreachable error is received, it indicates a...
this sends a SYN flag to the target and waits for a SYN-ACK response. In the event of a response, the scanner does not respond back, which means the TCP connection was not completed. Therefore, the interaction is not logged, but the sender learns if the port is open. This is a quic...
the receive window. If the window size is zero, the sender must wait for an ACK before sending the next chunk of data. If the receiver reports that the receive window size is larger than the size of a single data packet, the sender can send multiple packets without waiting for an ACK....
