I found this definition of Global Networks: Currently does any Global Network exists (apart from Internet)? I want to know are there any other global networks other than the internet? For example, the internet has two protocols - TCP and UDP. The book briefly talked about Telephone network as WAN(Apart from the internet).

My current conclusion is: L3 is better for local scenario (like localhost or Intranet) while L7 is for Internet. I'm also curious, if I use eBPF to offload this forwarding, can I let the packets go through the protocol stack to avoid the above situation? Data is sent from A to P, and then from P to B, and vice versa.

At the beginning of the day on 7 September 2021, AS749 wasn’t announcing any routes to the global internet. If the DoD had transitioned these routes to be announced by the “DoD’s traditional operations”, I would have expected them to be transited via AS721 which is how virtually all of the DoD IP address space is routed on the internet.

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.

In software, different systems agree on a protocol that describes the shape of the message. The protocol might be implicit, but typically, the more users a protocol has, the more it needs to be formally described. For example, look at the RFCs that describe the Internet. Without it, the message is meaningless.
