How Does The TCP Sender Understand Whether There Is Congestion In The Network? TCP detects congestion when it fails to receive an acknowledgement for a packet within the estimated timeout. In such a situation, it decreases the congestion window to one maximum segment size (MSS), and under other cases it increases the congestion window by
What Does Application Incomplete Mean On Palo Alto? Incomplete means that either the three-way TCP handshake did not complete or the three-way TCP handshake did complete but there was no data after the handshake to identify the application. In other words that traffic being seen is not really an application. What is incomplete in Palo
How Does TCP Set Its Timeout Value? Chapter 21 TCP sets a timeout when it sends data and if data is not acknowledged before timeout expires it retransmits data. Uses a doubling exponential back off How TCP timeout value is determined? When TCP sends a segment the timer starts and stops when the acknowledgment is

Hence this is the reason why TCP is the most commonly used application protocol for HTTP,FTP,SMTP,IMAP,POP3. What port does IMAP use? The ports typically used for POP are
What Is The 3 Way Handshake? A three-way handshake is a method used in a TCP/IP network to create a connection between a local host/client and server. … In fact, its name originates from the three messages transmitted by TCP before a session between the two ends is initiated. What is the right order of
Why Do Some Packets Have Sequence Numbers? The sequence number is a counter used to keep track of every byte sent outward by a host. If a TCP packet contains 1400 bytes of data, then the sequence number will be increased by 1400 after the packet is transmitted. At offset 64 is the acknowledgement number.
What Is The Advantage Of Sliding Window In TCP? The sliding window provides several benefits: It controls the speed of transmission so that no fast sender can overwhelm the slower receiver; It allows for orderly delivery, as we will show; It allows for retransmission of lost frames, specific retransmission policy depends on the specific implementations.
