Broadband Internet access is not a dedicated line to access the Internet

What is private line broadband, and which is better than home broadband? Today is a long time to see.

Leased line broadband refers to fixed IP, dedicated bandwidth, and optical fiber dedicated line broadband, which is directly connected to the operator's broadband server from the user's optical fiber.

Leased line broadband corresponds to shared broadband. Shared broadband means that a certain amount of bandwidth is shared by a community or building. The bandwidth rate handled by the user is only the maximum rate of the connection to the cell or to the switch port of the building.

If no one else is connected to the Internet, they can enjoy the broadband speed. If there are too many people surfing the Internet, the total egress capacity is not enough, and the Internet speed will slow down.

Telecom private line broadband is exclusive broadband, and home broadband is shared broadband; Ordinary broadband can meet the bandwidth, and the transmission capacity of private line is large; Ordinary broadband is slow because it is shared by multiple people. The leased line is used by independent units, and the number of users is small, the shared traffic is more, and the rate is faster. Anhui Telecom*** is at your service.

First, the reference is different.

1. Dial-up Internet access: refers to the steps and operation content of joining the Internet through local ** dial-up, from dialing 163xx (169xx) to being able to "wander" on the Internet.

2. Dedicated line networking: The types of private lines involved include ADSL private line, DDN private line, FR private line, and ATM private line.

3. Broadband Internet access: It can meet the bandwidth required for transmission on the network that people can feel.

Second, the speed is different.

1. Dial-up Internet access: the speed can only reach 56kb s.

2. Leased line Internet access: The rate range is between 64Kbps and 1Gbps.

3. Broadband Internet access: the rate can reach 10ms or even higher.

Third, the way is different.

1. Dial-up Internet access: As long as the user has a personal computer, an external or built-in modem and a ** line, and then apply for their own from the local ISP ** provider, or buy a network card, have their own username and password, and then connect to the Internet by dialing the ISP access number.

2. Dedicated line Internet access: When the data communication bandwidth required by the user is between 64Kbps and 2Mbps, and the user needs to have a fixed exclusive IP address, the user can choose this access method to establish his own mail server, web server and other servers, and can realize the company's internal VPN business through the Internet.

3. Broadband Internet access: It describes a wide range of frequencies that a signal or electronic circuit contains or can be processed at the same time. Broadband is a relative way of description, and the larger the frequency range, that is, the higher the bandwidth, the more data can be sent.

Private lines are generally used by companies.

The common Internet access includes private line access and broadband dial-up access, so what is the difference between private line and ordinary broadband? Here is the answer for you, optical fiber Internet access (dedicated line access) and ordinary broadband Internet access (ADSL) are two different ways to access the Internet, the biggest difference between the two is the difference in the transmission medium, optical fiber Internet access (dedicated line access) completes the transmission of optical signals, and ordinary broadband, that is, ADSL Internet access completes the transmission of electrical signals, so the speed of optical fiber Internet access will be much faster than ordinary broadband Internet access.

1. Optical fiber Internet access (private line access) has a fixed IP and ordinary broadband (ADSL) does not have a fixed IP, which is what we usually call a public IP, which is unique in the world, and it can be bound to the enterprise server as the unique identification of the external access server. And with a fixed IP, our network will be more stable, and we don't have to drop calls every three days like ordinary broadband (ADSL).

2. Optical fiber Internet access (private line access) is dual-channel, while ordinary broadband (ADSL) is one-way, usually we involve two aspects of broadband in the process of surfing the Internet, network uplink and network downlink. If you use ordinary broadband (ADSL) when uploading files, it will also be affected, which is determined by the one-way nature of ordinary broadband (ADSL), and the advantage of optical fiber Internet access (dedicated line access) is that the other party will not be affected when you upload or **, even if the upload bandwidth is full**.

3. Optical fiber Internet access (dedicated line access) is symmetrical in the uplink and downlink and ordinary broadband (ADSL) uplink is only 512K, if it is 5M optical fiber Internet access, ideally, its uplink and downlink bandwidth can run full and reach 5M at the same time, while ordinary broadband (ADSL) upload only has a maximum bandwidth of 512K, and if the upload occupies full bandwidth, its downlink will also be affected, and even drag down the entire network.

4. Different access levels in the network hierarchy architecture of optical fiber Internet access (private line access) and ordinary broadband access (ADSL) determine the different nodes, speed and stability.

5. Optical fiber Internet access (private line access) is an exclusive access mode, while ordinary broadband (ADSL) is a shared access mode, which determines that ordinary broadband (ADSL) will be affected by the peak period of Internet access, while optical fiber Internet access will not. Therefore, if you have special requirements for the stability, security and speed of enterprises or individuals, you still have to choose the private line access.

1. The users are differentPrivate line is a service for enterprises.

Home broadband is for home users.

2. The cost and speed are differentDedicated lines, high costs, consistent uplink and downlink speeds.

Home broadband, which is cheap, has a much lower uplink speed than a downlink speed.

3. The IP address and bandwidth are also differentLeased line, dedicated bandwidth, unlimited number of connections. Use a fixed public IP address (you can use this address to open external service functions such as **, FTP server, etc.). Telecom operators have special personnel to manage and monitor the use of this IP, so as not to do something that hinders the core ethics of socialism.

Home broadband, shared bandwidth, leased IP, the number of connections is limited, telecom operators have a fixed IP pool in the local area, and regularly allocate one of the IPs to themselves, and today they will be assigned to this IP, and tomorrow they may be assigned another IP.

Key features of leased line broadband.

1. High transmission quality and high channel utilization;

2. High transmission rate and small network delay;

3. The transparency of data and information transmission is high, which can support any procedure, and can transmit a variety of services such as voice, data, fax, image, etc.;

4. It is suitable for occasions with large data and information flow;

5. The network operation and management are simple, and there is no special requirement for the data transmission rate of the data terminal.

Leased broadband is mostly used for group customers such as enterprises, institutions, party and government agencies, etc., and generally operators use optical fiber from the computer room to jump to the user's home section by section, with the same uplink and downlink bandwidth, and a fixed public IP address is used, which does not require dial-up.

Ordinary home broadband includes ADSL, community metropolitan area network broadband, optical fiber exclusive three ways, here the optical fiber exclusive is the use of PON technology, is the use of optical fiber to the single fiber according to the splitting ratio to multiple users, there are 1:4, 1:8...

To 1:128 splitting, saving the largest investment in broadband network optical cable deployment, the uplink and downlink rates are not the same, and dial-up Internet access is required.

What is private line broadband, and which is better than home broadband? Today is a long time to see.

The main differences between private line broadband and regular broadband are their usage scenarios and quality of service. Specifically, there are mainly the following differences, which can be used for reference:

Usage scenarios: Private line broadband is commonly used in scenarios that require high-speed, stable, and reliable network connections, such as financial institutions, hospitals, and schools. Ordinary broadband, on the other hand, is a network service provided for ordinary households or enterprises, mainly used for simple applications such as Internet access, entertainment, and office.

2.Quality of service: Private line broadband has higher service quality, and its network stability, bandwidth, latency, and other indicators are higher, which can ensure the stability and efficiency of network connections of enterprises or institutions.

However, the service quality of ordinary broadband is relatively low, and indicators such as bandwidth and latency will be affected by factors such as network congestion and interference.

3.Dedicated line broadband is relatively high because of its higher service quality requirements, which requires more investment and maintenance costs. The ** of ordinary broadband is relatively low, which is suitable for the economic affordability of ordinary families and enterprises.

4.Fiber security: The data transmission of leased broadband is more secure and reliable, which can ensure the data security of enterprises or institutions. However, the security of ordinary rental and imitation broadband is relatively low, and it is easily affected by hacker attacks, virus infections and other problems.

In general, the difference between private line broadband and ordinary broadband mainly lies in its use scenarios and service quality, enterprises and institutions need higher network requirements and more reliable services, while home users and ordinary enterprise users pay more attention to ** and convenience.

What is a leased line and what is the difference between a leased line and a regular broadband?

The special line is owned by the Ministry of Industry and Information Technology of the People's Republic of China.

Qualified communication operators provide services for enterprises, and ordinary home broadband is for home users. A private line is a single optical fiber line, which runs directly from the operator's computer room to the enterprise computer room, and is full of optical fiber media, which is an exclusive bandwidth. In ordinary home broadband, the operator pulls an optical fiber to the cell computer room, connects it to the fiber switch, and then the community users share the bandwidth. Differences: 1. The optical fiber line is exclusively for the use of enterprises, and only enterprises can apply for it, and a business license is generally required for the record; Home broadband is only available for individual users and requires an ID card.

Can; 2. The guarantee is different, and the optical fiber dedicated line is generally restored within 3 hours; Home broadband is 24 hours or more; 3. The tariff is not the same, the optical fiber line 50m is also 3000 yuan, and the family 50m is about 1000 yuan per year; 4. The uplink and downlink of the dedicated line are symmetrical, that is, the upload and ** are the same speed, if the application is 50m, the uplink and ** speed are generally (50 8=, and the uplink and downlink are separated, and they do not affect each other; The uplink and downlink of home broadband are asymmetrical, and they have mutual influences. 5. The private line has a set of fixed IPs as if it were noisy, while the home broadband does not have a fixed IP, which is obtained dynamically; 6. The optical fiber dedicated line is stable, and the home broadband line is unstable; Connecting fiber optics and home bandwidth is on the way to the last mile.

When there is a distinction, generally in the backbone network.

They are together in the line, and the application supply is different after the node computer room of the specific project (such as an office building or a community). In short, carriers distinguish between enterprises and home users, with private lines as exclusive resources and ordinary broadband as shared resources. Different services and policies are implemented, so there is a difference between private line and home broadband in terms of ** and speed.

The differences between private line access and ordinary broadband are as follows:

1. The principle is different

Ordinary broadband Internet access is to divide the original ** line OKHZ to the frequency band into 256 sub-frequency bands with a frequency width. A private line is an independent network cable for an organization, that is, an independent local area network.

2. The safety performance is different

Because ordinary broadband Internet access is used by many users at the same time, the security performance is poor.

The leased line makes the user's data transmission reliable and trustworthy, and the security is very good.

3. The use of ** is different

Ordinary broadband Internet access is used by many people, and after apportionment, each household ** is very low;

Because the leased line is used by independent units, the rental** is relatively high, and the management also needs professionals.

4. The running rate is not the same

Ordinary broadband Internet access is slow because it is shared by multiple people;

Because leased lines are used by independent units, fewer users are used, more traffic is shared, and the rate is faster.

Ordinary broadband will also be affected when uploading files, which is determined by the one-way nature of ordinary broadband (ADSL), and the advantage of optical fiber Internet access (dedicated line access) is that the other party will not be affected when you upload or **, even if the upload bandwidth is full**.

5. The transmission medium is different

Ordinary broadband, i.e., ADSL Internet access, completes the transmission of electrical signals;

The leased line completes the transmission of optical signals.

6. The network equipment is different

Ordinary broadband optical modems are also called optical modems and single-port optical transceivers. The leased line is connected to a switch.
