In this project you will learn about router behavior by building another server using Python sockets, but rather than a web server, this one will handle two kinds messages:

• First, it can receive messages (UPDATE) updating routing information (in a sort of simplified version of BGP).
• Second, it can receive questions (QUERY) asking your server where it would route a message (Note that in reality, that wouldn’t happen – the router would just receive packets and route them, but for our exercise it will instead reply to messages asking “where” instead).
