UNIT
1
FUNDAMENTALS AND PHYSICAL LAYER

Building a network, Requirements, Data communication Components, Data representation and Data flow, Networks, Types of Connections, Topologies, Protocols and Standards, Layering and protocols, Internet Architecture, Network software, Performance, Transmission Media, Networking Devices. Lab Practice: 1.Learn to use commands like tcpdump, netstat, ifconfig, nslookup and traceroute. Capture ping and traceroute PDUs using a network protocol analyzer and examine. 2. Study on different types of networking devices.

UNIT
2
DATA LINK LAYER AND MEDIA ACCESS

Link layer Services, Framing, Error Detection and Error Correction, Flow control, Media access control, Random Access, CSMA/CD, CDMA/CA, Ethernet (802.3), Wireless LANs, 802.11,Virtual LANs Lab Practice: 1.Implement the data link layer framing methods such as character, character stuffing and bit stuffing. 2. Implement on a data set of characters the three CRC polynomials –CRC 12, CRC 16 and CRC CCIP.

UNIT
3
INTERNETWORKING AND ROUTING

Logical addressing, Basic Internetworking (IP, CIDR, ARP, BOOTP DHCP, ICMP), Routing algorithms, Routing(RIP, OSPF, metrics),Global Internet (Areas, BGP, IPv6), SDN. Lab Practice: 1. Implement Dijkstra‘s algorithm to compute the Shortest path through a graph 2.Take an example subnet graph with weights indicating delay between nodes. Now obtain Routing table art each node using distance vector routing algorithm.

UNIT
