2.  What it is?  OSI model.  History.  Objectives.  Encapsulation and decapsulation.  Multiplexing and demultiplexing.  Flow control.  Error detection.  Data transfer.  Implementation.  Conclusion

3. What is Dynamic TCP and Connection Elapsing ?

4.  When system design for load - balancing then  Move packet from one machine to another.  Without losing connection.  Packet are similar to the file - discryptor passing on a single host.

6.  In may 1974 By Vint cerf and Bob kahn.  RFC 793 which publish in 1981.  RFC 2581, latest RFC in recent years which publish in 2001.  TCP cookie trasmision in december 2009.

7.  Port address and socket addressing used for process-to-process communication.  How flow control, error control mechanism are implemented in TCP.  Introduce protocol and protocol rules.  Addressing TCP firewall specialized a device.

11.  TCP uses an end-to-end flow control.  Slow start.  Fast retransmission.  Fast recovery.  Based on window mechanism.

12.  Add redundant bits.  Redundant bits are used by receiver to detect error.  Algorithm based on addition of all the codes used to encode the data.  Receiver compares to copies equal then no error.

13. HostClient Send Packet 1 Start Timer Retransmit Packet1 Start Timer ACK would normally Arrive at this time Receive Packet 1 Send AXK 1 Time Expires Receive ACK 1 Cancel Timer Packet Lost

14.  Data will transfer from the client to host or host to client  Ordered data transfer the destination host rearranges according to the sequence number.  Retransmission of lost packets.

15.  You need to implement the tcp to establishment and termination of connection.  TCP is to build hardware implementation.  Modern implementation  Fast recovery.  Fast retransmision.

16.  We have discussed major components of network.  Knowing better understanding of networks builds physical and logical.  Knowing how packets are delivered from client to host or host to client.  A good understanding and identifying of networking of TCP.
