How Dedicated Line Access Works and How It Performs:
I. How It Works and Transmission Media
Dedicated line access: also known as leased line access, it uses dedicated communication lines (physical media such as fiber optics and coaxial cable) to connect a user’s computer or other terminal devices directly to the internet. This approach requires no forwarding through the public network, forming a closed network environment for data transmission.
II. Network Performance
Speed: Because dedicated line access uses exclusive bandwidth, its transmission speed is typically far higher than that of public network access, reaching up to Gbps-level transmission rates.
Stability: A dedicated line is also unaffected by public network congestion, ensuring a stable network connection.
III. Security
Dedicated line access: As a point-to-point exclusive channel that does not pass through the public network, it is difficult to attack from the outside, and the likelihood of data being intercepted in transit is extremely low, thus ensuring the security of data transmission.
IV. Quality of Service
Dedicated line access: It provides users with high-quality services including fault recovery time and regular maintenance, and guarantees through an SLA (Service Level Agreement) that users enjoy the promised level of service.
V. Cost and Use Cases
Cost: Because dedicated line access is provided for exclusive use, its price is relatively high, and it requires professional staff to manage.
Use cases: It is widely used in scenarios requiring high-speed, stable, and secure network connections, such as the data centers of large and very large enterprises, government agencies, financial institutions, and medical institutions.
