The revelation IDC Merchant Room price difference how big

Why do I visit my site quickly and slowly? Why is the same bandwidth, different room price difference so big? In the final analysis, the bandwidth quality of a sentence is different. With a few problems with netizens, small series visited several data centers, asked a lot of technical staff, learned some knowledge, share to everyone. I hope we can communicate together, qq:719323216.

First of all, learn theoretical knowledge, bandwidth quality by the access mode and bandwidth size together.

Bandwidth size: That is, we often say that 100M, 10M, 2M connection, which is easy to understand, generally speaking, our servers are equipped with 1000M network card, that is, the server itself to support the maximum speed of access to each 1000M. Of course, the reality is very cruel, take 100 cabinets of the computer room, merchants will buy 500m-1000m from the telecom operators in the hands of the bandwidth (this bandwidth is the real bandwidth speed, expensive OH), evenly distributed to each cabinet of the bandwidth naturally only 5m-10m around, To a cabinet of 16 machines to calculate, remove some small scale no flow of servers, leisure may be able to run a 1m-2m, network busy, I am afraid you can really use the bandwidth of only hundreds of K, which is our most common 100M sharing. Many data centers provide free flow monitoring software, such as the Fun data center PRTG real-time traffic monitoring, can be intuitive to help us monitor bandwidth consumption at any time. Those so-called dozens of g to the engine room, 100M to the cabinet, is simply Arabian Nights, if there is such a commitment to the business, early or say good-bye, lest be fooled again, to know that a China telecom in a province in a total of the bandwidth for the IDC business is only dozens of G, is it to a merchant? One more thing to remind you , the so-called 100M bandwidth refers to the uplink and downlink (out and into) the highest flow of 100M, if there are businesses to tell you the total 100M traffic flow is definitely black oh. To understand the difference between exclusive and sharing, you can see another article in the small series, "revealing IDC businesses--the difference between sharing and shared bandwidth" (http://www.admin5.com/article/20091030/188774.shtml).

To figure out the bandwidth size, it's not hard to understand why websites can be slow in the morning or at some point in time. Simply put, the more the total bandwidth purchased from the merchant, the better the bandwidth we gain, and the more expensive the price of the room.

Access mode: The access mode is composed of several elements, such as connection line, routing mode and connection node. Connection line is what we often say the single, dual-line (telecommunications, Unicom), multi-line (telecommunications, unicom, education Network, the Great Wall Network and other operators) computer room; routing means static, BGP routing connections; the connection node refers to a backbone node connected to the operator or a provincial node or a city-level node. Of course, the best access mode is the core node of multi line BGP connection backbone network.

Just now we said that businesses want to buy bandwidth from operators, which access to the bandwidth can be very fastidious. First, the more the number of connected operators the better (that is, multi-line room is better than two lines, double-line machine room is better than single machine room); 2nd, and the most important point, directly connected to the backbone of the bandwidth quality far better than the network connected to the province, better connected to the city-level network nodes. For example, my site's main clients are from Guangzhou and Shanghai, if my room is directly connected to the backbone network, then when the customer visit the network flow is "Guangzhou node-> backbone network Node", as long as one step can be achieved; if my room is connected to the bandwidth of Langfang, Hebei, then when the customer visit the network flow is " Guangzhou node-> backbone node-> Beijing node-> Hebei node-> langfang node, need to take four steps to achieve, the speed is certainly slower than the backbone network access way a lot.

Therefore, the difference of access mode and bandwidth also leads to the difference of network bandwidth quality directly. The same bandwidth size, access to different nodes, the merchant out of the money is also very large, not even a order of magnitude, which is why the price difference between the room is so big.

Have to mention is that there is a kind of room, such as telecommunications, unicom, mobile, education Network, the Great Wall network, economic and trade network of these Chinese Internet operators their own room, because they have their own national network (the entire Chinese Internet is composed of these several networks), their network status is the highest, all BGP multi-line interconnection, Bandwidth quality is the best, and these room bandwidth cost is actually the lowest, this is like power supply bureau cheap. Such computer rooms are generally used by operators themselves, a small number of also to the merchant agent. Telecommunications, Unicom, mobile more powerful, to the merchant's agent price is also quite expensive, education network, the Great Wall network, economic and trade network of these room network quality is very high, agent price is much lower, friend unit of the server hosted in the Fun Data center of the Great Wall Network backbone room, although is the third-tier BGP link backbone network, but the price is very low oh. Small series think, let everyone choose high quality low-cost room is the hard truth, said so much theoretical knowledge, how can we now use or intend to use the room bandwidth quality how? together look forward to the next "uncover IDC business-test the true bandwidth quality" bar.
