What are the four major limitations of today’s Internet?
The four major limitations of today’s Internet are bandwidth, quality of service, network architecture, and language development. There is insufficient bandwidth capacity throughout the backbone, the metropolitan switching centers, and most importantly, to the houses and small businesses at the end of the information pipeline. Due to insufficient bandwidth and the circuitous nature of packet switching, video and voice traffic suffers from latency. This causes these types of messages to arrive with noticeable delays and a jerky quality. Because today’s Internet uses “best efforts” quality of service, each packet is provided with the same level of service. This means that all packets traveling through the communication system are treated the same, no matter who is sending them or what type of message they are.
Network architecture restrictions also limit the performance of the Internet. A thousand requests for the same file result in a server having to download the file one thousand times rather than being able to transmit it once to all one thousand computers at the same time. This significantly slows down network performance. Finally, HTML, the language for displaying Web pages, has proven to be insufficient for displaying rich documents such as database files, business documents, and graphics.
