This course is about strengthening the Networking concepts and fundamentals with assignments and projects side by side with theory. Through this course you will be able to :
1. Understand the Functioning of TCP/IP Stack (OSI Model). Understand the function of each layer in TCP/IP stack in good detail.
2. Explain the L2 routing concepts – Mac Addresses and ARP
3. Explain the L3 routing concepts – IP Addresses and IP protocol
4. Understand various ways to design a Linux TCP/UDP server program in C
5. Understand Socket programming in C
6. Understand the Networking devices functioning – L2 switch and L3 router
7. Understand packet Journey through the layers of TCP/IP stack
8. Design and implement HTTP Webservers from scratch
9. Read and manufacture the network packets from scratch
10. Do various coding assignments and projects to hands-on the concepts
11. Wheel Timers as a periodic packet dispatchers
12. Understand the concept of TLVs
We Understand – Networking by its nature is inclined towards being a theoretical subject of study. To arouse the interest of the students ,we elaborate each and every topic of this course through an assignment or project.
This course is backed by two Networking projects where we explain the problem statement with description in detail and guide the student from the beginning of the project towards completion of the project. The projects are completely in line with the concepts and Demos shown and taught in the course.
This course is thorough and completely coding based. We explain the design, discuss the code flow and then guide the audience how to implement the particular concept design in detail in a step by step manner. All you need is a Linux OS running on your system to do this course.
Who should do this course ?
This course is meant for UG Computer science students, job seekers and professional developers. This is MUST do course for those who want to join MNCs as a developer. The topics covered in this course are of utmost importance from interviews aspects and students graduating in computer science and looking to seek an opportunity in MNCs as a developer should have Networking concepts at his/her finger tips.
Better to have done Networking under graduate course, not mandatory.
Job seekers trying for the position of Networking developers in product based MNCs
System software development including Networking is an evergreen area. Internet will not going to be doomed ever.
There is no pre-requisite for this course, however, it shall be advantage if you know a little of C. We designed this course assuming student is a complete beginner in Networking and we raise the level of course gradually as we move from Basic to advance Networking concepts.
Also, Please just do not sit and watch my codes. Write your own codes, even if it is same as mine !
We have a strong reasons to choose C as a language for this course:
1. The entire core networking development work is being done in C in industry. So, this reason alone is good enough that you should learn network development in C if you are aiming to join industry as a network protocol developer.
2. Network equipment need to interact with underlying hardware – the ASIC chips. What could be a better language other than C when it comes to interact and program the hardware.
3. C is middle level language – not as low as assembly, neither as high as Java/Python. In C, its the programmer’s responsibility to write every line of code to get the task done, unlike Java/Python which provides rich rest of libraries to do the most tasks for you. Using High Level Languages for learning network programming would obscure the low level details of networking – that is what is going behind the scenes. If you are are beginner in network programming, you must learn things from scratch and only C provides you the opportunity to do that. So, you must do all your assignments in C.
4. Networking is all about cooking up the packets and sending it out of wire. C will allow you to cook packets exactly the same way as you would like them to appear on wire. Lot of Bit level programming.
5. If you are a beginner in Networking, pls refrain from learning network programming in High Level Languages such as Java Or Python. It is not job oriented thing to do in networking domain.
No Third Party libraries
Whatever logic you implement, you need to implement it from scratch. This course do not suggest taking help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third party libraries for commonly used data structures such as linked lists/Trees/Queues etc which saves a lot of time implementing these data structures.
