TCP/IP (Transfer Control Protocol / Internet Protocol)
TCP/IP family was developed for the ARPANET
It was initially designed and operated to interconnect the very large university and industrial defense communities to share researchresources
The TCP/IP suite of protocols has wide acceptance today, especially in the commercial and industrial community worldwide These protocols are used on both LANs and WANs They are particularly
attractive for their Internet-working capabilities
Trang 5TCP/IP Stack vs the OSI
Model
Trang 6encoding, and dialog control
The TCP/IP model combines all application-related issues into one layer and ensures that this data is properly packaged for the next layer
TCP/IP Stack
Trang 7provides for network communications.

TCP/IP Architectural Model
Trang 16 Operates at transport layer of OSI and TCP/IP models
Provides applications with access to the network layer without the overhead of reliability mechanisms
Is a connectionless protocol
Provides limited error checking
Provides best-effort delivery
Has no data-recovery features

IP Network Addressing
Network.Host
They uniquely identify each device on an IP network
Every host (computer, networking device, peripheral) must have a unique address.

Trang 26ICMP (Internet Control Message protocol)
ICMP is used as an adjunct to IP
ICMP messages are sent to report errors in the processing of datagrams:
When the router can direct the host
to send traffic on a shorter route
