Study Notes
Internet Structure and Organizations
- IETF (Internet Engineering Task Force): Develops and promotes voluntary internet standards.
- ICANN (Internet Corporation for Assigned Names and Numbers): Coordinates the assignment of domain names and IP addresses.
- IAB (Internet Architecture Board): Provides architectural oversight for the internet.
Intranets and Extranets
- Intranet: A secure internal network owned by an organization, only accessible to authorized users.
- Extranet: Access point allowing authorized external users to interact with an organization's data securely.
Internet Access Technologies
- Home users commonly connect through options such as broadband cable, DSL, wireless WANs, and mobile services.
- Organizations typically require faster connections for functionalities like VoIP, video conferencing, and data storage.
- Business-class connections may include DSL, leased lines, and Metro Ethernet.
Converged Networks
- Converged data networks allow simultaneous transmission of data, voice, and video over a single infrastructure.
- A unified set of rules and standards governs the infrastructure for these services.
Reliable Networks: Network Architecture
- Fault Tolerance: Networks are designed to minimize the impact of failures by ensuring multiple paths for data transmission.
- Scalability: Ability to expand without degrading performance for existing services, supported by adherence to standards and protocols.
- Quality of Service (QoS): Mechanism to ensure reliable delivery of voice and video content through bandwidth management.
- Security: Encompasses both network infrastructure security (preventing unauthorized access) and information security (ensuring data confidentiality and integrity).
Network Security Goals
- Confidentiality: Ensures that only intended recipients can access data.
- Integrity: Guarantees that data remains unaltered during transmission.
- Availability: Provides timely and reliable access to data for authorized users.
Current and Emerging Network Trends
- Organizations must adapt to trends such as Bring Your Own Device (BYOD), online collaboration, video communications, and cloud computing.
- Cloud Computing Types:
- Public Clouds: Open to general public, often pay-per-use.
- Private Clouds: Designed for specific organizations (e.g., government).
- Hybrid Clouds: Combine elements of public and private clouds.
- Custom Clouds: Tailored to specific industry needs, can be public or private.
Smart Home Technology
- Increasing integration of technology in everyday appliances to improve interconnectivity, such as smart ovens that sync with calendars.
Powerline Networking
- Allows devices to connect to a LAN using electrical outlets, bypassing the need for data cables or Wi-Fi.
- Effective solution for areas where wireless coverage is weak or non-existent.
