Definition
Network Architecture
The design and structure of a computer network, including its physical and logical layout, communication protocols, and data transmission methods.
Definition
Protocol
A set of rules that defines how data is transmitted and received over a network.
Definition
Standards
An agreed-upon specification that ensures compatibility and interoperability between different systems and technologies.
- The future of the web depends on the evolution of its underlying infrastructure, which includes network architecture, protocols, and standards.
- These components ensure the web remains scalable, secure, and accessible as it grows.
Network Architecture
Scalability
- As the number of internet users and connected devices grows, network architecture must support scalability.
- This involves:
- Decentralization: Reducing reliance on central servers to prevent bottlenecks.
- Edge Computing: Processing data closer to the source to reduce latency.
Edge computing is becoming essential for applications like autonomous vehicles and smart cities, where real-time data processing is critical.
Security
- Security is a major concern in network architecture.
- Future developments include:
- Zero Trust Models: Assuming no device or user is trusted by default.
- Quantum-Resistant Encryption: Preparing for the potential threat of quantum computers breaking current encryption methods.
- Many students assume that encryption is a one-time solution.
- In reality, encryption methods must evolve to counter new threats, such as quantum computing.
Energy Efficiency
- With the rise of data centers and cloud computing, energy efficiency is crucial.
- Techniques include:
- Optimizing Data Transmission: Reducing redundant data transfers.
- Green Data Centers: Using renewable energy sources and efficient cooling systems.
- Green computing is not just an environmental concern.
- It also reduces operational costs for companies.
Protocols
HTTP/3 and Beyond
- The Hypertext Transfer Protocol (HTTP) is the foundation of data communication on the web.
- HTTP/3 introduces:
- QUIC Protocol: Reduces latency by establishing faster connections.
- Improved Security: Encrypts more data by default.
HTTP/3 is already being adopted by major companies like Google and Facebook to improve user experience.
