Teach you to buy and understand the bandwidth and traffic of the virtual host, the difference between sharing and exclusive

When it comes to bandwidth, it involves bandwidth units, bandwidth is generally used in bits per second, English is bps, such as ADSL bandwidth is 2mbps, is actually 2mbit per second. The front of the M, there is a corresponding k, g everyone should have encountered, said the order of magnitude, the system is 1024, the estimated time can also be simple to replace with 1000. which is 1g=1024m1m=1024k.

Bandwidth is an important factor in determining the speed of host accessOne, especially for the number of visitsLarge site, the size of the bandwidth is particularlyImportant. And the flow is actuallyThe accumulation of bandwidth in time,It's mathematically said to takeThe integral of a wide pair of times. Make aPopular metaphor, take the tap., bandwidth is actually water.The velocity of the tube, and the flow isThe total amount of water flowing out.

Because bandwidth and traffic are critical for a virtual host,Before you choose a virtual host, you shouldA good understanding of this concept,Or it's easy to get caught up in the mainframe businessLeisurely Once you know, you'll be big.I know what the mainframe says.Some words are believable and which areNot credible, can also be eliminatedMistaken knowledge of many people. IHere are a few thingsTo introduce, in some ways justIn order to better understand these twoConcept, for the purchase of virtual ownersThere is no direct connection to the machine.

A. Easily confusing two bits: byte and bit

When it comes to bandwidth, it involvesBandwidth of the unit, the bandwidth is generallyIn bits per second, in English.Is bps, such as adsThe bandwidth of L is 2mbps, which is actually 2mbi.T per second. The front of the M, alsoThere is a corresponding k, g everyone should have met,Indicates the order of magnitude, the system is 1.024, the estimated time alsoYou can simply use the 1000Replace. which is 1g=1.024m1m=1024K. (Communication is a progressive system1000, but for the estimateSmall impact)

People who use computers are usually familiar.Notes such notions as IThe hard drive is 160G. ThisWhat does a 160G mean?is actually 160G Byte, which is 16.0G bytes so that everyoneYes, this one and the above.The 2MB is not the sameOf

Byte and bit relationships: abyte equals 8bit。
When the initials were two, they were all B., accustomed to the byte abbreviationWith uppercase B, and bitWith a lowercase b, but a lot ofWhen writing is confusing, soSee the bandwidth of the host logo toLet's find out if it's byte orIs bit. Generally speaking, room bandwidth, host port bandwidth areIt's bit, but some of the mainMachine limits peak bandwidth, and thisA host commercial bytE, some use bit, phase8 times times worse, so make sureChu (if it is written in bps, generally refers to bit)。

two. Sharing and Exclusive

This virtual host doesn't usually say, only when the host is renting and hosting it will be mentioned, because the virtualThe intended host must be sharing a server's bandwidth, not exclusive.But because the virtual host isFrom the server,So still understand the server'sThe bandwidth situation is better. DomesticCommon is the 100M sharingand 10M Exclusive, 100M sharing is actually a machineCabinet to share a 100MPorts, as for each serverHow much can be divided depends on theNumber of servers in a cabinet andBandwidth consumption per serverSituation and 10M alone,is to give each server A10M of Port. Generally tosaid that 100M shared eachThe loan to the server is approximatelyAt 2M to 5M, the10M Exclusive is superior to 100M shared.

Domestic use of the virtual host serviceMost of the service is 100M totalEnjoy, also have 10M exclusive, but some say his service100M is the only one who's going to be careful.A lot of suspicion.

In addition to the above said, in fact aThe band that a server can be divided intoWidth also depends on the whole roomThe bandwidth is plentiful. 10MExclusive OR 100M aloneEnjoy actually just 10M portor 100M port to receiveOn the switch, do an extremeexample, suppose the room gives youA 100M port, butis the engine room to the public net export realOnly 10M on the internet, thenIn fact, your maximum bandwidth isIt's 10M. From thissense that the 100M aloneEnjoy is actually still shared, notis to put your exit into the mainDry online. Another freshman level,If one of the backbone networks is congestedis to give you a 1G port to connectTo the backbone of the network, the same bandwidthWill limit. So the exclusive and totalEnjoy is actually relative.

In general, if a machineThe outlet bandwidth of the room is 10G, divided to servers or cabinetsThe bandwidth cumulative value is greater than theA value, which is called the SuperSell. If not oversold, 10G of bandwidth can only be divided to 100 Hundred m shared cabinet。 Because not every serviceThe device will be full every moment.Wide, oversold will be more full of benefitsWith resources. The belt of the virtual hostWide and other resources are and thisThe truth is similar, will also saveIn the phenomenon of oversold but onlyIf it's reasonable, it's all right.Households and the host is advantageous.About the virtual host oversold pointsAnalysis of our special introduction later.

three. Flow rate

Many host business, especially the United StatesNational host will limit traffic,So let's analyze the flow.The specific concept of quantity, feeling aUnder

1.10M Maximum monthly traffic for Exclusive server:

The bandwidth used is bit, theSo don't forget 8 times times the difference.Calculated as follows
(10m x 3600 x x30)/(1024x8) =3164GB
