Annotation
The inexorable law of computer networks says: everything that was small will become big; everything that was big will become huge; everything that was huge will turn into a transnational network. The main purpose of the book - to acquaint the reader with the rules of 'good form' in the design of large-scale computer networks. After all, the key to a stable network lies precisely in its proper design, and not in a super-fast transmission medium or high-performance switches and routers. The book is intended for network designers and highly qualified users.

Answer 10

I can offer to contact on Skype, go through the main protocols and scenarios for their use. If this format is interesting - write in a personal. I always wanted to try to teach someone something. Although I don’t have much experience yet (I have CCNP R&S, CCDA certificates, 3 years enikey, then 2 network engineer, now I work in Poland in an international company), but I can definitely tell you the basics.
