Where can I read about the architecture of ISP networks, how are they built?

Question

Computer networks

Hello. I would like to find some more or less detailed information about the organization of provider networks. Googled - found nothing interesting. Maybe someone knows some books (if any) or articles (where you can look). Thanks

Answer 1

All the books that you will find on the networks, the provider's network actually does not differ much from your home network - only the cost of iron and routing.
