Why is the uplink and downlink speed asymmetrical of telecom broadband?

1. For LAN or FTTH access broadband users:

1) Broadband with a downlink rate of less than or equal to 4Mbps and an uplink rate of 512kbps;

2) For broadband with a downlink rate greater than 4Mbps but less than 20Mbps, the uplink rate is 1Mbps;

3) For broadband with a downlink rate greater than or equal to 20Mbps but less than 100Mbps, the uplink rate is 2Mbit/s;

4) Broadband with a downlink rate equal to 100Mbps and an uplink rate of 4Mbps.

5) Broadband with a downlink rate equal to 200Mbps and an uplink rate of 10Mbps.

2. For the broadband accessed by ADSL ADSL2+ VDSL, the uplink rate is 512Kbps.

This is the case for civilian networks, and only enterprise private lines are the same for both uplink and downlink.

For the early broadband, ADSL is the mainstay, and the technology limits its uplink to 512K, and the later ADSL2+ supports a slightly higher uplink, but it seems that it has not been promoted on a large scale in China Telecom and Unicom, although the equipment is almost completely ADSL2+ board.

Slightly later, the fiber to the building community, 5 types of line to the home, the technical up and down are symmetrical, but in view of the fact that the tariff of this type of user is the same as ADSL, it is easy to be complained by users when doing different **, so many times the uplink speed limit is 512K. FTTH, which is now open to PON technology, also follows this habit.

Why can't telecom give users higher upload speeds? In the past, users didn't need it, but now they all use P2P, and they need a higher upload speed. Because Telecom also builds a machine room, many of the best servers need to be placed in the computer room, and these servers need upstream traffic.

In addition, telecom should also consider what to do if users do not put servers in the telecom room, but build their own computer rooms to pull fiber strips. Therefore, in addition to limiting the uplink bandwidth, there are also restrictions in two aspects, one is that ordinary users cannot get a fixed IP address, and the other is to restrict access to port 80 for ordinary users. If you want 10Mbps uplink and downlink fiber, plus a fixed IP address?

Yes, the annual fee is 10 times that of ordinary 10m fiber.

In the case of ADSL, this is a technical limitation, which is itself asymmetrical, with a maximum uplink of 510kb

In order to ensure the bandwidth resources on the telecommunication transmission network.

The money spent is different.,Now it's basically downlinked.,General company fixed IP.,Uplink and downlink are equal.,Conventional household,4M,Downlink 4M,Uplink Now 100M's broadband uplink can reach up to 20M,Normal is 4M.Or 10m

Quite simply, the upside is gold and the downside is scrap metal.

Dear Telecom users, Hello!

According to your description, the higher the bandwidth, the faster the uplink speed. If you have any questions, please contact the consultation office or 10000, and ask the staff and engineers to answer them in detail. Hope it helps.

If you need to buy a machine, you can go to Anhui Telecom Tianyi store (hundreds of mobile phones are low on the whole network.

Really, is it so fast.

It won't be a LAN café.

1. According to the information you provide, if you are a broadband user of China Unicom Guangdong, the types of broadband provided by China Unicom Guangdong mainly include FTTH, XDSL, LAN, HFC, and enterprise private lines, among which the uplink and downlink rates of FTTH, XDSL, LAN, HFC broadband are asymmetrical, and the uplink and downlink rates of enterprise private line broadband are the same. Go to the local Unicom's own business hall to apply for enterprise private line broadband, which is much more expensive for other broadband types.

2. Usually 10Mbps high-speed broadband**The normal rate is 100kb s uplink and 1000kb s downlink, if the bandwidth you use is very different from the theoretical rate of the bandwidth, you can contact the local contact Jiqingtong manual customer service to report the fault, and our company will check and deal with it for you as soon as possible.

Because broadband technology itself is asymmetrical, not only telecom broadband, but also broadband around the world is asymmetrical.

Reason: Optical fiber technology itself is symmetrical in the uplink and downlink, and the asymmetry in the uplink and downlink should be mainly a commercial consideration for telecom companies

First, cost savings (large throughput and more equipment).

The second is to distinguish between household users and government and enterprise users (the monthly cost is 1,000 yuan, which is far more expensive than 480 yuan a year for family users).

It is advisable to peruse the terms of the contract with the telecommunications company. The compromise is to increase the speed of the uplink by adding money.
