Topic of the day
Ip utilities
TCP/IP MODEL
APPLICATION LAYERDefine TCP/IP application protocols.
Define how host program interface with transport layer to use the network.
Examples – HTTP, Telnet, FTP, TFTP, SNMP, DNS, SMTP etc.
TRANSPORT LAYERProvide communication session management between host computers.
It can be categorized as either connection-oriented (TCP) or connectionless (UDP).
Examples – TCP, UDP, SCTP
INTERNET LAYERHost addressing and identification: This is accomplished with a hierarchical addressing system.
Packet routing: This is the basic task of getting packets of data from source to destination by sending them to the next network node closer to the final destination.
Packages data into IP datagram.
Examples – IP, ICMP, ARP, RARP
NETWORK INTERFACE LAYER
Specify the details of how data is physically sent through the network.
Specify how bits are electrically signaled by hardware device that interface directly with a network medium.
Examples- Ethernet, FDDI, X.25, V.35, frame relay etc.
USER DATAGRAM PROTOCOL
Process to process protocol
Connection-less protocol
Unreliable transport protocol
Use to send small message
TCPProvides full transport-layer services to applications.
Designed for point-to-point communications between computers on same network.
Reliable stream transport protocol.
Connection-oriented.
SCTPProvides support for newer applications.
It is a transport layer protocol that combines the best features of UDP and TCP.
It also provides multi homing support.
IPIt is used for communicating data across a packet-switched internetwork using internet protocol suite.
Primary protocol in the internet layer.
Unreliable and connectionless protocol.
It transport data in packets called datagram.
BASIC FUNCTION OF IPData transfer
Packet addressing
Packet routing
Fragmentation
Simple detection of packet errors
DEFINITION TCP/IP provides several handy tool or
utilities for troubleshooting, investigating and analyzing the network.

1. ARP
ARP – address resolution protocolArp is used to convert ip address of a given system into their respective MAC address

If ip address is unique why do we need MAC?????????

Trace route
Used to find the exact path used.The hop or count number is givenIf the packet reach higher count it dies
