- The First Stage of The Internet
The initial phase of the internet, centered around ARPANET (Advanced Research Projects Agency Network) in 1969, had several defining characteristics:
- Fast and reliable (intended, but limited in practice): Despite the stated requirement for reliability in the event of a nuclear attack, the initial ARPANET network of four interconnected computers was prone to crashes and disconnections.
- Packet Switching: This was a groundbreaking feature, dividing data into smaller 'packets' that could travel independently and reassemble at the destination, improving efficiency and resilience.
- Decentralized Architecture: ARPANET was built to withstand single points of failure by using a distributed network where each computer could communicate with multiple others, rerouting data around damaged or congested areas.
- Uses IPv4: Although developed later as a protocol suit, the principles of IP address allocation for routing across different networks were laid down during the ARPANET era.
- Very low speeds: Early internet connections were incredibly slow by modern standards. Even in the 1990s, when commercial internet was becoming available, dial-up speeds averaged around 56 kilobits per second (Kbps).
- No Quality of Service (QoS): Bandwidth wasn't guaranteed in the early days. There were no mechanisms in place to prioritize certain types of traffic (e.g., real-time voice or video) over others.
- Limited Bandwidth: Early networks struggled with limited bandwidth capacity, making downloads and online activities slow and frustrating compared to today's experience with broadband and fiber optic connections.
- The Second Stage of The Internet
The second stage Internet is a major step towards developing the Internet. This development which has so far been only in the research arena is moving to the implementation arena.
The "Second Generation Internet" refers to a significant advancement in internet technology beyond the initial basic web browsing, focusing on the development and implementation of more advanced services like multimedia, quality of service (QoS), and IPv6, primarily driven by research and education institutions like Internet2, NGI, and CAnet2, with the goal of enabling applications like telemedicine and virtual laboratories that weren't possible with the older internet infrastructure.
Key points about the Second Generation Internet:
- Advanced features: It aims to introduce functionalities like IPv6 (the newer version of the internet protocol), multicast for efficient data distribution to multiple recipients, and QoS to prioritize certain traffic types.
- Collaborative effort: The development of Second Generation Internet is a collaborative project involving various universities, research institutions, and industry partners, with organizations like Internet2 being a key player.
- Focus on research and education: The primary goal is to enhance internet capabilities for research and education purposes, enabling advanced applications like telemedicine, digital libraries, and virtual laboratories.
- Major initiatives: Some prominent Second Generation Internet initiatives include I2 (Internet2), NGI (Next Generation Internet), and CAnet2, which are working towards developing and deploying the new technologies.
- The Third Stage of The Internet
The Third Stage of the Internet, also sometimes referred to as the Third Generation Internet, began around 1995 and marked a significant shift in its development.
Essentially, the Third Stage of the Internet transformed it from a government and academic domain into a global commercial platform, laying the groundwork for the modern Internet with its speed, accessibility, and diverse services.
