Anyone with hands-on experience setting up long-haul VPNs over the Internet knows its not a pleasant exercise. It lies at the core of how the Internet was built, its protocols, and how service providers implemented their routing layer. From the early days of the Internet, routers were shaped by technical constraints.

Message integrity and guaranteed delivery with TCP/IP Because IP does not require acknowledgments from endpoints, it does not ensure delivery; therefore, it is considered an unreliable protocol.

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. Each BGP speaking organization is assigned an Autonomous System Number (ASN) that identifies them on the Internet. They can then announce the routes (groups of IP addresses) that they own from their ASN.
