Exclusive bandwidth free selection of power users have the trick

It is reported that China's electrical business development is entering a critical point. Predicting that in the next few years, traditional sales will be almost zero growth, the traditional retail industry will be a large number of reducing stores, profits, gift costs, today's traditional retail giants or will be in 2014 losses, more retail companies will be through E-commerce to seek a breakthrough.





Shanghai, as China's economic center, brings together many Internet enterprises, in the field of electric business, not only has a number of shops, Xun nets and other industry leaders, but also has achieved excellent performance, the industry has been widely concerned about the forces. Their success stems not only from their own continuous innovation and unremitting efforts, Shanghai excellent Internet environment and rich room, bandwidth resources reserves for these achievements have laid a good material base. From the point of view of the operation of the Electric business website, the good room and the bandwidth resources can provide the most basic guarantee for the fast access and stable operation of the website. From the perspective of the development of electric business enterprises, the migration to the cloud will also be inseparable from the excellent room and the support of bandwidth resources. Whether it is the deployment of server and network equipment, or the future of the physical computing resources, storage resources of the cloud applications, has a good bandwidth security is an indispensable condition.








Taobao last year, "Double 11" to win more than 19 billion of the brilliant record, also inseparable from adequate bandwidth security, we can not imagine a frequent drop in the speed of the site can be very slow to win such a huge sales. From this point of view, whether have sufficient bandwidth reserves and capacity to expand has become an electronic business site can be an important factor in success.





recently, the major media, including CCTV, have exposed a group of broadband access operators that use "bandwidth" for false publicity. They use the average consumer's knowledge of the Internet, use the words "exclusive", "exclusive" and so on to render the network bandwidth that is actually shared to the individual user, the "exclusive bandwidth" used separately, and falsely mark the amount of bandwidth, entice the user to open an account and earn ill-gotten gains. In the area of broadband access for people, after repeated exposure and guidance of the media, the "bandwidth" of the essence has been understood, ordinary users will not easily believe that the flying false advertising in the sky, the enterprise-class users of the Internet access Services, "bandwidth" is not known to everyone? How should electric business enterprise choose when buying network bandwidth?





First, let's say the type of bandwidth. Under normal circumstances, IDC service provider provides two kinds of bandwidth mode for the user to choose, one is called "shared bandwidth", that is, a number of customers of several servers to use a network interface, the network interface can be connected to the cabinet, can also connect to a server, this way, the advantage is that the price is cheap, disadvantage is easy to affect each other , the network quality fluctuation is large, suitable for the network environment requirements are not high users; another kind is called "exclusive bandwidth", the exclusive bandwidth refers to the user will server and network equipment to the IDC room, and IDC service provider's core equipment side directly linked, and divided into separate subnets, alone to enjoy IDC service providers to provide bandwidth resources. Exclusive bandwidth can be divided into independent VLAN, control broadcast domain, isolated broadcast storm, suitable for network security, bandwidth quality, bandwidth scalability has a higher demand for customers. It is clear that for a more sophisticated electronic business site, the purchase of exclusive bandwidth is the choice of bandwidth.





How to distinguish the exclusive bandwidth, to avoid buying a fake exclusive? After visiting the well-known IDC service providers in Shanghai century Interconnection, the editor also learned some basic methods of discrimination. Electric dealer users can be identified in the following two ways:





1, check whether its equipment is allied to IDC's core equipment. This method needs the user to IDC service provider's network structure is more familiar, and also wants the network service provider to cooperate, realizes more cumbersome.





2, this approach is recommended by assigning to the user's IP address and subnet mask for identification. Users can use the view subnet mask to determine the number of hosts available in the allocated network segment, usually the user gets the first address is the network number, the second is the gateway, the last is the broadcast number, the other addresses are available addresses. The number of IP and subnet masks that the user obtains is equal to 256, then the address that the user obtains is exclusive, otherwise it is shared. The specific corresponding relationship is shown in the following table:





corresponds to the above table for example, If 255.255.255.0 this subnet mask corresponds to the number of available hosts 253, but the user can only use two IP addresses, it means that within these 253 addresses, there will be other hosts and the user share the export bandwidth, the user is not buying real exclusive bandwidth. Although the price is cheap, the false exclusive bandwidth cannot guarantee the network quality. With both of these methods, we have a good idea of how to buy bandwidth.





Most of the electrical business users in the selection of computer rooms, hosting the server will also carry out bandwidth testing, with the IP address provided by the provider for network speed, bandwidth peak, connectivity, packet loss rate and other items analysis. After obtaining the satisfactory test data, the server is hosted here. This method of selection from the technical point of view, from the actual use of the effect, but there are different results. Why is that? The reason is simple, the test bandwidth is not the same as the actual bandwidth used. We do not discuss the implied problems, to see how to select a qualified supplier, the right choice, naturally will not be deceived.





First, check the qualification





operator qualification is mainly IDC (the first category of telecom value-added services IDC room operating qualification), ISP (second category of value-added services in the Internet Access Service qualification), ICP (second category of value-added services business of the Internet Content Service qualification) three categories. At present, the domestic IDC market is mixed, light Shanghai, there are no less than 200 IDC service providers, a lot of qualifications are not complete, the electrical business users must choose the qualified supplier to buy bandwidth. If the supplier can come up with more qualifications to measure whether he has a certain service capability, we can go to the Communications Authority's website to inquire what qualifications they have.





second, look at the computer room





Room is the IDC service provider to provide services, but also the electronic business users of the server and network equipment, the final destination. At present, IDC service providers of the main room has agents, self-employed two kinds. Agent room may be due to the issue of resources to the electricity business users to bring the later expansion, the trouble of the machine; The proprietary room is the IDC service provider's own operation, the cabinet, the bandwidth resources control higher, the later expansion relatively easy, the service is also more timely. If the future development of planning, we recommend that the electric business users as far as possible to choose IDC Service provider of the proprietary room.





third, look at service





IDC service provider services mainly involved in the General Service, technical support Services two aspects. Routine service mainly refers to pre-sale consulting, expansion, renewal, etc., technical support services mainly refers to the equipment room racks, equipment maintenance, emergency response. Because the service content involves all aspects, some only can experience after the transaction, the electric business user in the judgment supplier Service ability can from the service system comprehensiveness, the service process consummation two aspects. See if they provide detailed information on whether there is a sound service management process. For example, Shanghai century Interconnection provides "full responsibility", "full redundancy" 7x24 customer service, "One-stop" complaint solutions, "full customer satisfaction monitoring", these specific service content and management methods is a good reference standard.





so far, this article editor of the electrical business users in the identification of exclusive bandwidth, select the right supplier and other aspects of the problems encountered to do a detailed analysis and solutions, I hope that the vast number of electrical customers can find suitable for their IDC service providers, I wish E-commerce in China's development all the way changhong.
