OBJECTIVES:
The student should be made to:
 Understand the division of network functionalities into layers.
 Be familiar with the components required to build different types of networks
 Be exposed to the required functionality at each layer
 Learn the flow control and congestion control algorithms

UNIT I FUNDAMENTALS & LINK LAYER 9
Building a network – Requirements - Layering and protocols - Internet Architecture – Network
software – Performance ; Link layer Services - Framing - Error Detection - Flow control

UNIT II MEDIA ACCESS & INTERNETWORKING 9
Media access control - Ethernet (802.3) - Wireless LANs – 802.11 – Bluetooth - Switching and
bridging – Basic Internetworking (IP, CIDR, ARP, DHCP,ICMP )

UNIT III ROUTING 9
Routing (RIP, OSPF, metrics) – Switch basics – Global Internet (Areas, BGP, IPv6), Multicast –
addresses – multicast routing (DVMRP, PIM)

UNIT IV TRANSPORT LAYER 9
Overview of Transport layer - UDP - Reliable byte stream (TCP) - Connection management - Flow
control - Retransmission – TCP Congestion control - Congestion avoidance (DECbit, RED) – QoS –
Application requirements

UNIT V APPLICATION LAYER 9
Traditional applications -Electronic Mail (SMTP, POP3, IMAP, MIME) – HTTP – Web Services – DNS - SNMP

OUTCOMES:
At the end of the course, the student should be able to:
 Identify the components required to build different types of networks
 Choose the required functionality at each layer for given application
 Identify solution for each functionality at each layer
 Trace the flow of information from one node to another node in the network
