Study Notes
Network Types and Convergence
- Traditional networks in schools 30 years ago operated on separate systems for data, voice, and video, each with unique technologies and standards.
- Converged networks integrate data, voice, and video services into a single infrastructure, utilizing the same protocols for ease of communication across diverse devices.
Network Architecture
- Network Architecture underpins how data is transmitted across the infrastructure.
- Four critical characteristics essential for architecture to meet user demands include:
- Fault Tolerance
- Scalability
- Quality of Service (QoS)
- Security
Fault Tolerance
- Fault-tolerant networks minimize service impact during failures, protecting multiple devices by employing redundant pathways.
- Packet-switched networks enhance reliability by splitting data into packets that may take varied routes to reach the destination, compared to the fixed routes of circuit-switched networks.
Scalability
- Scalable networks are designed to expand to accommodate new users and applications without degrading performance for current users.
- Adhering to established standards and protocols is vital for scalability in network design.
Quality of Service (QoS)
- QoS ensures that services like voice and live video meet high delivery standards without interruptions caused by inadequate bandwidth.
- A well-structured QoS policy allows network routers to effectively manage traffic flow, improving reliability for both data and voice communications.
Network Security
- Network security encompasses two primary types:
- Infrastructure Security: Protects network devices and management software from unauthorized access.
- Information Security: Safeguards data being transmitted across the network.
- Key goals of comprehensive network security include:
- Confidentiality: Ensuring only intended recipients can access data.
- Integrity: Guaranteeing data accuracy throughout transmission.
- Availability: Ensuring timely access to data for authorized users.
