Lec-65: TCP: Transmission control protocol | TCP Header | Transport layer | part -2

[@safionweb]

This video saved my many hours of reading the stupid slides given by my lecturer.

[@arindamkashyap2077]

🎯 Key Takeaways for quick navigation:
00:01 📊 *TCP Header Length*
- TCP header has a minimum size of 20 bytes.
- Header length is represented in 4 bits, multiplied by 4 to get the actual size.
- Valid header length values range from 0101 to 1111.
02:18 🚩 *TCP Flags Overview*
- Flags include URG, ACK, PSH, RST, SYN, and FIN.
- URG flag indicates urgent data, ACK for acknowledgment, and PSH for pushing data immediately.
- Understanding the purpose of each flag is crucial for effective communication.
07:08 🪟 *TCP Window Size*
- The window size is a 16-bit value, representing the capacity for data transmission.
- It is advertised by both sender and receiver to manage flow control.
- Ensures optimal data transfer within the network's capacity.
09:30 🔍 *Checksum and Urgent Pointer*
- Checksum, a 16-bit value, is used for error control in TCP.
- Urgent pointer, also 16-bit, indicates the range of urgent data in the payload.
- Both contribute to the reliability and accuracy of data transmission.
10:26 📡 *TCP Options and Padding*
- Options and padding allow for additional data in the TCP header.
- Maximum Segment Size (MSS) is a critical value specified in options.
- Understanding MSS and window size prevents confusion in network communication.

00:06 TCP header length should be a minimum of 20 bytes
01:41 Header length in TCP/IP packet determines the size of the header in bytes
03:23 Acknowledgement numbers are used to confirm data receipt.
05:01 Push is a mechanism to send data immediately without waiting for a bundle
06:17 TCP connection and its flags
07:58 TCP uses window size for flow control and capacity advertisement
09:30 Understanding Urgent Pointer and Option and Padding in Network Communication
11:10 TCP communication involves MSS and window size

bahut badhiyaaaa varun bhai

Best!TheBEST!!!
Sir ThankYouu!!!

[@prashreetiwasti7264]

Your way of teaching is excellent sir

[@praneshjoshi5927]

Hi Sir,
1) is window size measured in bytes ?
2)
if window size > MSS --> we can fit the MSS into window size
if window size < MSS --> here which one will be compromised?
thank you.

[@Prashant-jc3nn]
