CS602 Computer Networks Unit 4 study material for RGPV CSE 6th Semester. This unit covers Network Layer, routing algorithms, IP addressing, subnetting, IPv4, IPv6 and internetworking concepts.
Unit 4 explains how packets travel from source to destination across different networks. It focuses on routing, logical addressing, subnetting and IP protocols used in real internet communication.
Learn shortest path routing, flooding, distance vector routing and link state routing.
Understand IPv4 addressing, classes, subnetting and logical addressing.
Study IPv4, IPv6, packet forwarding and communication between different networks.
Complete syllabus-based topics of CS602 Computer Networks Unit 4.
Functions, responsibilities and role of Network Layer in packet delivery.
Concept of routing, routing tables and path selection in networks.
Finding minimum cost path between source and destination nodes.
A routing method where incoming packets are sent on all outgoing links.
Routing based on distance and direction information shared between routers.
Routing method where routers build complete network topology information.
IPv4 address structure, classes, network ID, host ID and address types.
Dividing a larger network into smaller subnetworks for efficient address usage.
Internet Protocol versions, header format basics and comparison.
Process of forwarding packets from router to router until destination is reached.
Upload your PDFs in the pdfs folder with the same file names used below.
These questions are useful for 7 marks and 14 marks answers in RGPV exams.
Network Layer is responsible for logical addressing, routing and packet forwarding from source to destination across multiple networks.
Shortest Path Routing, Flooding, Distance Vector Routing and Link State Routing are important for RGPV exams.
Yes, subnetting is very important because it is used to divide a large network into smaller subnetworks and is often asked in exams.
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses and provides a much larger address space.
Based on previous RGPV examinations, these topics are repeatedly asked from Unit 4.
