Notes for AL-602
- Unit 1 · Short notes Computer Network: Definitions, goals, components, Architecture, Classifications & Types; Layered Architecture; ISO/OSI Reference Model; Physical Layer Principles Definitions, goals, components, architecture, classifications and types of computer networks. · Protocol hierarchy and layered architecture, including design issues, interfaces and services. · Connection‑oriented and connectionless services and associated service primitives. · ISO/OSI reference model and its comparison with the TCP/IP model. · Physical layer principles: transmission media, bandwidth, data rate and modulation schemes.
- Unit 2 · Short notes Data Link Layer Data link layer functions: services, framing, flow control and error control. · Elementary and sliding‑window protocols (1‑bit, Go‑Back‑N, Selective‑Repeat, Hybrid ARQ). · Protocol verification using finite‑state‑machine and Petri‑net models. · ARP, RARP and GARP protocols.
- Unit 3 · Short notes MAC Sub‑layer MAC sub‑layer addressing and the Binary Exponential Back‑off (BEB) algorithm. · Random access and contention schemes (ALOHA, Slotted ALOHA, CSMA, CSMA/CD, CSMA/CA). · Collision‑free protocols (Basic Bit Map, BRAP, Binary Count Down, MLMA, Adaptive Tree Walk). · Performance‑measuring metrics for MAC protocols. · IEEE 802 series standards and their variants.
- Unit 4 · Short notes Network Layer Network layer services, design issues and routing algorithms (Least‑Cost, Dijkstra, Bellman‑Ford, hierarchical, broadcast, multicast). · IP addressing, header format, packet forwarding, fragmentation and reassembly. · ICMP functionality. · Comparative study of IPv4 and IPv6.
- Unit 5 · Short notes Transport and Application Layers Transport layer design issues, UDP header format, checksum and support for unicast/multicast real‑time traffic. · TCP connection management, reliability mechanisms, flow control, congestion control, header format and timer management. · Application layer protocols: HTTP/WWW, FTP, SSH, SMTP/MIME/IMAP, DNS, and network management (SNMP).
