Networking and the Internet TCP /IP Protocol Suite Dr. M. Tanvir Afzal  The TCP/IP Protocol Suite Need Published standards so that manufacturers can supply equipment and software that could function well with products of other vendors. Open System Interconnection (OSI) 2  The TCP/IP Protocol Suite OSI Reference Model By International Organization for Standardization. Seven level hierarchy as compared to four level hierarchy we just learnt Remained slow in replacing the 4 level hierarchy as it was already in use. 3  The TCP/IP Protocol Suite TCP and IP TCP Suite is collection of large number of protocols to implement four level hierarchy Entire collection is referred to as TCP/IP-misleading. Transmission Control Protocol Internet Protocol 4  The TCP/IP Protocol Suite TCP version TCP defines a version of transport layer. More than one way of implementing transport layer either for TCP or UDP (User Datagram protocol) This is similar to choosing different shipping company 5  The TCP/IP Protocol Suite Differences between TCP and UDP TCP establishes a connection first while UDP does not. UDP is called connectionless protocol Destination might not be operational! 6  The TCP/IP Protocol Suite Differences between TCP and UDP TCP transport layers at origin and destination works together by acknowledgement and retransmission i.e. called reliable protocol. UDP unreliable protocol 7  The TCP/IP Protocol Suite Differences between TCP and UDP TCP can adjust the transmission rate to avoid control Congestion. 8  The TCP/IP Protocol Suite UDP benefits Transport layer based on UDP is more streamlined than TCP. UDP is perfect choice when receiver is ready like DNS Lookups, VOIP, Although in emails transfer, TCP is better choice. 9  The TCP/IP Protocol Suite IP Internet Protocol is a standard to implement the network layer (we have already talked). Forwarding and routing. Hop count: adding a value at origin by which time the packet should be forwarded normally 64 is sufficient. 1  Summary TCP/IP Protocol Suite OSI TCP version UDP Differences between TCP and UDP IP 1
