Firstly, we must ask ourselves whether "More is Better". Is it advisable to permit the increase to go on? The answer must be yes, since the market has chosen this technology, but that we must solve the scaling problems first and foremost.
Another interesting question to ask ourselves is: What were the original Internet requirements? The Internet evolved out of a defense experiment, with special requirements for robustness above all else. This has led to the possibility of running a severely under-engineered network and still get useful service from it. We need to persuade the Public Network Operators to provide a properly engineered Internet service (somewhat like the latest NSFNet service in the US). This is covered in more detail in chapter 10.
Luckily, the community, the Internet Engineering Task Force (IETF) have this attitude: Better leads to more anyhow!
The next generation of the Internet is going to be based on a protocol called the Simple Internet Protocol Plus, now known as IP6, using a variety of mechanisms to improve all the services above.
