COURSE OBJECTIVES: 302 4
To understand the concept of layering in networks. To know the functions of protocols of each layer of TCP/IP protocol suite. To visualize the end-to-end flow of information. To learn the functions of network layer and the various routing protocols To familiarize the functions and protocols of the Transport layer UNIT I INTRODUCTION AND APPLICATION LAYER 10 Data Communication - Networks – Network Types – Protocol Layering – TCP/IP Protocol suite –OSI Model – Introduction to Sockets - Application Layer protocols: HTTP – FTP – Email protocols(SMTP - POP3 - IMAP - MIME) – DNS – SNMP UNIT II TRANSPORT LAYER 9 Introduction - Transport-Layer Protocols: UDP – TCP: Connection Management – Flow control -Congestion Control - Congestion avoidance (DECbit, RED) – SCTP – Quality of Service UNIT III NETWORK LAYER 7 Switching : Packet Switching - Internet protocol - IPV4 – IP Addressing – Subnetting - IPV6, ARP,RARP, ICMP, DHCP UNIT IV ROUTING 7 Routing and protocols: Unicast routing - Distance Vector Routing - RIP - Link State Routing – OSPF– Path-vector routing - BGP - Multicast Routing: DVMRP – PIM.
