What will be an ideal response?
The Internet communication backbone is an interconnected network of backbones owned by businesses or NSPs. Much like an anatomical backbone, where nerve signals travel across the spinal cord, an Internet backbone provides a conduit for network communication between different points of Internet access.
Routers direct network traffic to its destination via routing tables and updates from routing protocols. Routers in NSP backbones differ from routers in a LAN by the high amount of traffic they are designed to handle and the routing protocols they use for the Internet backbone environment. The physical memory, CPU speeds, interfaces, and operating systems
(OSs) of routers used in NSP backbones can support enormous amounts of traffic and large
routing tables.
