Transmission technology, switching technology, access technology. The broadband transmission network is mainly based on SDH (Synchronous Digital Series) based on large-capacity optical fiber networks; The broadband switching network is an integrated service digital network using ATM (asynchronous transmission mode) technology. Broadband access networks mainly include optical fiber access, copper access, hybrid optical fiber copper access, wireless access, etc.
Generally, the speed of dial-up Internet access is 512k, 1m, etc., and the speed of wireless network is generally 11m or 55m. (Note: 1m=1024k, 1g=1024m) data transmission rate is one of the important technical indicators to describe the data transmission system.
The data transfer rate is numerically equal to the number of binary bits per second that make up the data** transmitted, measured in bit second, and denoted as bps.
3,3Mbps is 3 million bits (bits) per second. M is the abbreviation of million, that is: million.
The 3 million came from this: 3Mbps = 3 1Mbps = 3 1024kbps 1024bps = 3145728bps) that is, theoretically, a maximum of 393216 bytes of data are transmitted per second. The formation of kb is theoretically about 384, but in practice it is about 320.
It is important to know that the greater the bandwidth, the higher the loss.
4, And so on:
Formula: A few megabytes of bandwidth 1024 8=several kbs
5, so the traffic available for distribution of 50m broadband is 6400kb per second.
-
The maximum speed of 50M broadband (generally not playable) is to try to set the total speed of the whole network minus the bandwidth assigned to the other two departments when the network management department** file is set to the upper limit of the speed of the network management department? Then look for software for this!
-
"100M" is 100 megabyte traffic. m means trillion and can also be written as mb. Mobile Internet traffic is based on GB, MB, KB as the unit, mobile data traffic unit conversion relationship:
1024byte=1kb;1024kb=1mb;1024mb=1gb;1024gb=1tb。
-
20 megabytes (m) = gigabytes (g).
1g = 1024m, what is the flow rate of 20m g, use the division 20 1024, the result can be obtained.
1b (byte) = 8 bit;
1kb (kilobyte, kilobyte) = 1024b = 2 10 b;
1MB (megabyte, megabyte, megabyte, abbreviated as "megabyte" zhi) = 1024KB = 2 20 B.
1gb=1021mb。
-
20m=20*1024*1024b (bytes)
2.The conversion relationship between them is: 1MB=8 1MBPS, do you understand?
Look at it in another way: 1Mbps 8 = 128KB That is to say, the operator calls 10M broadband, and the actual speed is 10Mbps 8 = 1280KB, approximately.
3.What many people may not know is that the server hosted in the computer room requires a large amount of uplink bandwidth, and the cost of 10M uplink in the computer room is 5-6 times that of the 100M broadband at home. Therefore, the practice of giving downlink bandwidth to home users and uplink bandwidth to enterprise users in the computer room has become an important means for broadband operators to make profits.
-
These two concepts are not the same and are not comparable.
-
How many mb s should be measured for a 200 megabyte broadband network
-
The amount of traffic available for distribution in 50M broadband is 6400kb per second.
The details are as follows: 1. Introduction.
China United Network Communications Group (hereinafter referred to as "China Unicom") was established on January 6, 2009 on the basis of the merger of the original China Netcom and the original China Unicom, with branches in 31 provinces (autonomous regions and municipalities directly under the central government) and many overseas countries and regions, and is the only telecommunications operator listed in New York, Hong Kong and Shanghai at the same time, and has been selected as one of the "Fortune 500 Enterprises" for many years.
2. Company development.
On April 28, 2009, China Unicom launched a new full-service brand "Wo", which carries the service concept of China Unicom consistently adheres to innovation and provides comprehensive support for individual customers, family customers and group customers.
3. Logo interpretation.
China Unicom's corporate logo is an evolution of the ancient Chinese auspicious graphic "Pan Chang" pattern. The lines that circulate through the loop symbolize the orderly and smooth operation of China Unicom as a modern telecommunications company, as well as the inexhaustibility of the earlier Unicom business.

Broadband and traffic are not the same thing, bandwidth is equivalent to the road equivalent to the highway, the traffic is equivalent to how many cars pass through the highway, the highway is wide and there is no channel, and the traffic is also 0.
Learn about Broadband & Data:
1. M of broadband is a megabyte to describe the speed of data traffic.
2. The g of the flow rate is 1g=1024m describing the total amount of transmitted data.
-
100M home broadband is unmetered and time-limited**.
100 Gigabit optical fiber refers to the traffic of the network cable, the traffic of using optical fiber Internet access can reach up to 100Mbit s (stand-alone test), 100 Gigabit optical fiber uses optical fiber access, which transmits signals in the form of optical pulses, compared with the previous dial-up Internet, the transmission speed of optical fiber is much faster. ,
-
Broadband 100m and traffic 100m are different concepts, 100m broadband can be used for unlimited Internet access without traffic restrictions. Broadband is equivalent to the road equivalent to the highway, and the traffic is equivalent to how many cars pass through the highway.
Traffic is a digital record, mobile Internet traffic records the number of bytes consumed by a web page on a mobile phone, the unit is b, kb, mb, gb. An English character needs 1b, and a Chinese character needs 2b, and a ** is generally a few kb. Generally speaking, the web page on the mobile phone is tens of kb per page, which is tens of thousands of bs (1kb = 1024b).

I didn't say it after a lap.,Just say how much traffic is equivalent to 100 megabyte broadband.,Say a bunch of useless people can't understand it at all.,It's different.,After all, you can say that 100 megabyte broadband is enough for a mobile phone to watch TV and movies for a month.,It's okay! I have to say that it's not the same thing.,It's all traffic.,It's just that the megabyte conversion can't be remembered.,Just say no.,Or just say 100 megabytes of broadband almost a thousand giga.,No.,No one said that.,It's all nonsense.。
-
These two don't matter, the general situation is 100m maximum speed, not a concept.
-
Bandwidth and traffic are not the same thing.
The bandwidth is equivalent to that of a highway equivalent.
The flow is equivalent to how many cars pass through the highway, and the highway is not open to traffic in the wide, and the flow is also 0
-
100M broadband is casually on, and there is no restriction on traffic.
Re-make a system By the way, bring your questions to the person who made the system, you can't ask what the result is, 3-4 people use it, is it a router problem, theoretically speaking, it shouldn't be stuck.
