6. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server

7. The proxy server evaluates the request according to its filtering rules ( filter traffic by IP address or protocol)

8. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client

11. Routers utilize routing tables and headers to settle the finest passageway for the package to follow

12. Routing protocols might be utilized by routers to communicate with each other and make the most excellent path between any two nodes or hosts on a network system
