## GUJARAT TECHNOLOGICAL UNIVERSITY ## Program Name: Diploma Engineering Level: Diploma Branch: Computer Engineering / Computer Science and Engineering Subject Code : DI04000301 Subject Name : Advance Computer Network W.E. F. Academic Year: 2025-26 Semester: 4 th Category of the Course: Professional Elective - I Prerequisite: Students should possess basic knowledge of computer networks, including OSI and TCP/IP models, IP addressing, and sub netting, as covered in the Computer Network subject. Rationale: In today's connected world, computer networks are the foundation of communication and information sharing among people, businesses, and organizations. As technology grows and the need for fast, reliable communication increases, skilled professionals are required to design, set up, and manage these networks. This course on Advanced Computer Networks helps students understand different networking concepts and protocols. It covers topics like IPv4 and IPv6, routing protocols such as RIP, OSPF, and BGP, and transport layer protocols like TCP and UDP. Students will also learn about application layer protocols such as HTTP, SMTP, POP3, IMAP4, and DNS. Through practical exercises, students will gain hands-on experience in configuring networks, troubleshooting issues, and analyzing network traffic. By the end of the course, they will have the skills and knowledge needed to design, implement, and manage advanced computer networks and understand how different layers and protocols work together. ## Course Outcome: After Completion of the Course, Student will able to: | No | Course Outcomes | RBT Level | |------|-----------------------------------------------------------------------------------------------------------------------------|-------------| | 01 | Describe IPv4 addressing, packet forwarding, and ICMP tools for network communication. | Understand | | 02 | Apply routing algorithms and RIP, OSPF, BGP protocols for unicast routing configuration. | Apply | | 03 | Analyze and use transport layer protocols TCP and UDP to establish reliable and connectionless communication. | Understand | | 04 | Implement and test application layer protocols HTTP, FTP, DNS, and Email in a simulated networking environment. | Apply | | 05 | Interpret IPv6 addressing, packet structure, and transition techniques to ensure compatibility with IPv4 networks. | Understand | *Revised Bloom's Taxonomy (RBT) Page 1 of 7 ## GUJARAT TECHNOLOGICAL UNIVERSITY Program Name: Diploma Engineering Level: Diploma Branch: Computer Engineering / Computer Science and Engineering Subject Code : DI04000301 Subject Name : Advance Computer Network ## Teaching and Examination Scheme: | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Teaching Scheme (in Hours) | Total Credits L+T+ (PR/2) | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Assessment Pattern and Marks | Total | |-------------------------------|-------------------------------|-------------------------------|------------------------------|--------------------------------|--------------------------------|--------------------------------|--------------------------------|---------| | L | T | PR | C | Theory | Theory | Tutorial / Practical | Tutorial / Practical | Marks | | L | T | PR | C | ESE (E) | PA (M) | PA (I) | ESE (V) | Marks | | 3 | 0 | 2 | 4 | 70 | 30 | 20 | 30 | 150 | ## Course Content: | Unit No. | Content | No. of Hours | % of Weightage | |-------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------|-------------------| | 1 | Network Layer  Introduction -
