CS6551 COMPUTER NETWORKS
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
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
Media access control - Ethernet (802.3) - Wireless LANs – 802.11 – Bluetooth - Switching and bridging – Basic Internetworking (IP, CIDR, ARP, DHCP,ICMP )
UNIT III ROUTING
Routing (RIP, OSPF, metrics) – Switch basics – Global Internet (Areas, BGP, IPv6), Multicast – addresses – multicast routing (DVMRP, PIM)
UNIT IV TRANSPORT LAYER
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
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
