ABSTRACT
Throughout its history, the Internet has seen repeated improvements and enhancements to patch the inherent flaws in its initial design-and they are many. The Internet is traditionally not plug-and-play because nodes and networks need elaborate set-up and configuration processes. Other prominent flaws include its ability to support only best-effort QoS, lack of security, inability to support mobility in the real sense, and the limited address space provisioned in IPv4.
