This useful troubleshooting command for cmd provides information about network speed and network loss at every node between a source and destination. Pathping sends Echo Requests to every router between a source and destination and then calculates the results based on the packets returned from every device. By displaying the percentage of packet loss at any given node, we can see which router have some network problems. Pathping is making the same thing like tracert command but with more information about every router on the way.

BGP is the Internet routing protocol. He is making the Internet work.

BGP protocol performs actions by maintaining IP networks table for the biggest network in the world – The Internet. The BGP protocol, as a code of behavior, supported core routing decisions over the Internet.  Instead of using traditional IGP (Interior Gateway Protocol) metrics, BGP protocol relies upon available path, network guidelines and rule-sets for routing decision making purposes. And just for this feature, it is sometimes expressed as a reachability protocol. The main idea behind the BGP creation was to replace the EGP (Exterior Gateway Protocol) to permit a complete decentralized routing. NSFNET backbone is the best example of a decentralized system.

A router is basically a computer like PC. We we see now all about router hardware components and what are they doing inside router

Routers have many of the same hardware and software components that are found in computers:

• RAM
• ROM
• CPU
• Operating System

Routers job is to determine the best path for a packet across the network

The primary responsibility of a router is to forward packets to local or remote network by deciding the best path to send packets and then forward packets toward their destination using that path.

If we speak about what is networking and then try explain how does networking work or maybe how does internet work in some technical way, soon we will have to mention the routing protocols. We should mention routing protocols as the most important networking protocols when it comes to transfer packets from origin to destination points on the network. After all they are responsible for finding the best way across our multipath network.
