What is the definition of a dedicated Internet line? What is an Internet leased line?

Internet line:

Internet private line is a dedicated network connection service provided by telecom operators. It connects users and internet service providers (ISPs) over dedicated lines to provide a higher quality network connection.

The construction of Internet dedicated lines can provide higher bandwidth and lower latency, thereby improving users' Internet experience. For enterprise users, the Internet private line can ensure the stability and security of the enterprise's internal network, and improve the production efficiency and competitiveness of the enterprise. For individual users, the Internet line can provide faster upload speed and smoother ****** experience.

Internet line:

An international Internet line refers to a private line service that connects domestic users with the Internet. Since the international Internet connection needs to cross national borders and pass through network nodes in multiple countries and regions, the construction and maintenance of international Internet private lines are more complex than domestic Internet private lines. In order to ensure the stability and speed of the connection, the international Internet dedicated line usually chooses a more reliable optical cable transmission method instead of the traditional Internet transmission mode.

The construction of international Internet private lines is also very important for multinational enterprises and international enterprises. With the development of globalization, more and more enterprises need real-time data transmission and communication with overseas branches, merchants and customers. The Internet line can provide a more stable and efficient network connection to ensure the smooth operation of cross-border business.

Internet line:Usually refers to a high-speed, stable network connection that is designed to connect a user or business to a network of Internet Service Providers (ISPs). This type of connection typically provides a large amount of bandwidth to meet the user's need for fast, reliable Internet access.

Internet leased lines can be various technologies such as optical fiber, Ethernet, DSL, etc., and their choice depends on the user's needs and available infrastructure.

Internet line:is a leased line that connects networks in different countries or regions. Because international connections involve crossing borders, their bandwidth and quality requirements are often higher.

The Internet line provides a direct international network connection, enabling users to transmit data and access Internet services worldwide, such as visiting foreign countries**, conducting network communications for multinational enterprises, etc. This connection is usually provided by a professional international internet service provider to ensure the stability and efficiency of data transmission across different countries.

The difference between the Internet private line and it is that the former generally refers to the access to the domestic Internet, while the latter is customized for international Internet access.

Internet private line access provides customers with dedicated links of various rates (mainly providing transmission rates of 2M and above), directly connecting to the IP backbone network, and realizing convenient and fast high-speed Internet access services.

Features of Internet dedicated line:

1. The customer accesses the Internet through a relatively permanent communication line.

2. The international private line maintains a permanent, high-speed and stable connection with the Internet, so that customers can achieve 24-hour access to the Internet, obtain global information resources at any time, and improve the efficiency of business transactions.

3. Private line customers have a fixed real IP address, which can provide information services to other customers on the Internet relatively conveniently.

4. The leased line has the characteristics of low bit error rate and low latency. The entire circuit resource of dedicated bandwidth is only for one customer, and the whole bandwidth is completely exclusive.

1. connect the network access equipment between the dedicated line user and the external public network, and make the pin punch described network access device and the special line user form a virtual local area network.

2. using the network connection combustion penetration equipment to bind and authenticate the dedicated line user, and the binding authentication may be carried out in the network access equipment, or may be carried out from the remote network equipment through the broadband access equipment.

The network line also includes steps to provide uniformly configured service quality assurance attributes for leased line users, and can assign addresses and verify the legitimacy of users under the Layer 2 virtual LAN leased line.

Network private line refers to the operator relying on the domestic backbone network and broadband metropolitan area network resources to provide private line access mode, for enterprises, ** and other customers with higher data access requirements to provide more high-quality and professional services.

It is a user-exclusive, high-speed, secure, and stable communication line, which can support a variety of services such as data mountain, voice, and image, and meet the high standards of network quality and performance required by users.

For example, if an enterprise has two branches in Beijing and Shanghai, and needs to frequently conduct a large amount of data and business exchanges such as ** conferences, then they can apply to the operator for a network line to connect the two branches. In this way, they can enjoy the advantages of exclusive bandwidth, low latency, and high security, without being affected by the traffic of other users on the public Internet.

A dedicated network line refers to an independent network line provided for an organization or organization, which is not shared with other users, and can ensure the security, stability and efficiency of data transmission.

It has the advantage of avoiding congestion, latency, and attacks on the public network, and improving the quality and reliability of network communication.

There are many types of leased network lines, which are mainly distinguished by the medium, rate, and range of the line. Common types of private network lines are as follows:

DDN private line: It uses digital data network as the transmission medium, with high transmission rate, and supports a variety of services such as data, voice, and image, which is suitable for customers with high security requirements such as finance and insurance.

PCM SDH dedicated line: It uses pulse code modulation or synchronous digital layer as the transmission medium, which can provide digital data dedicated line services from 2M to 155M rate, as well as other services such as voice and image, which is suitable for customers with high requirements for data transmission rate.

Optical fiber dedicated line: using optical fiber as the transmission medium, the transmission distance is long, the speed is fast, the loss is low, the anti-interference ability is strong, can provide 10Mbps, 100Mbps, 1000Mbps high-speed broadband, suitable for group users and intelligent communities, hotels, business buildings, campus networks and other high-speed access to the Internet.

International Private Line (IPLC): The use of international private leased circuits as the transmission medium, refers to the communication lines of comprehensive information services such as data and voice for the exclusive use of users, which can undertake the safe, stable, high-speed, and low-error rate transmission of large data volumes, and is suitable for companies with high-quality data and voice communication needs with overseas companies.

To put it simply, a private network line is like a private lane from your home to your destination, which only you can use and will not be affected by other vehicles, while a public network is like a congested public road with many vehicles to share and may encounter traffic jams, accidents, or violations.

Qiaochaishou network dedicated line refers to the network line used independently by an organization, which is equivalent to an independent local area network, and the purpose is to ensure the security of data transmission for mega chaos. The advantage of the network line is that it has good security and is not easy to leak data. However, the maintenance cost of the network leased line is high and requires professional personnel to manage it.

There are two main channels of filial piety and suspicion of network dedicated lines, as follows:

1. Physical dedicated channel: The physical dedicated channel is to lay a special line between the service provider and the user, and the line is only used independently by the user.

2. Virtual private channel: The virtual private channel is to reserve a certain bandwidth for users on the general channel, so that users can enjoy this part of the bandwidth exclusively. In addition, the user's data is encrypted to ensure the security of the user's data.

The key to building a global Internet is to arrange nodes to participate in network distribution.

The key to building an international private line IPLC is to solve the global distribution problems, which include:

The problem of limited export bandwidth in various countries.

Firewall problems: The interconnection and interconnection links of various operators are broken, especially the access problems of operators.

Problems caused by changes in international network routing.

Choice of network transport protocol.

Implementation of congestion control algorithms.

Real-time pin monitoring and intelligent scheduling when link quality changes.

As we all know, broadband is mainly divided into two types: private line and home broadband, generally speaking, enterprise servers and cloud service providers usually use private line service broadband, while ordinary families are generally connected to home broadband. What is a leased line network? What is the difference between private line and home broadband?

Next, I will popularize science by Tengyi Network.

Private line refers to the business of relying on domestic backbone network and broadband metropolitan area network resources to provide private line access mode to meet the needs of enterprise group customers to access the Internet network and carry out various applications.

For example, China Mobile's current Internet private lines are divided into two types: PON access private lines and PTN access private lines.

Access rate and bandwidth are not the same concept.

"Access rate" refers to the rate that the "access line" can achieve, which is the maximum speed limit on the road, for example, the speed limit on the general highway is 120kmh. Generally speaking, the higher the access rate, the shorter the waiting time for the Internet and the better the user experience.

Bandwidth represents the ability of a communication line to transmit data. "Bandwidth" is like the width of the road in the highway system, and increasing the bandwidth is equivalent to widening the road so that the car can run more and faster.

A dedicated line is like a road just for you.

The private line is a dedicated link provided by the operator to the group customers at various speeds, directly connected to the backbone network, and realized convenient and fast high-speed Internet access services. Customers can access the Internet through wired and wireless methods, and the bandwidth can be flexibly selected.
