Description

System and Method for Using Server by Regional Groups by Using Network and Storing Medium and Recording Medium}

The present invention relates to at least two or more data centers or servers distributed in a domestic and overseas region in a coordinated process so as to recognize the equivalence in technical configuration and / or function performance for predetermined data processing through a predetermined cooperation agreement. In a switching server (or relay server) for identifying and switching a data center or server having a low data processing cost among centers or servers, when a client requests data processing from the data center or server or switching server (or relay server), The switching server (or relay server) determines a data center or server having a low data processing cost for data processing requested by the client from the data center or server, and switching the client to the determined data center or server And provide system It is.

In a client server-based network, a client requests at least one content from a server, and the server serves to provide the corresponding content in response to the client's request, and the server provides a fast content generation and providing function. In addition, a network infrastructure for rapidly transmitting the generated content to a client through a network should be provided. If the server does not meet the above requirements, the server operator or server operator operating the server may suffer more costly damage than the data processing cost.

However, in the case of the server leasing service as described above, although the cost burden is reduced compared to directly building and operating the server, it is not efficient in terms of utilization and management of the server. There were also costs associated with operating.

Therefore, in order to maximize the server utilization of such servers, the server construction cost is borne by a server operator or an operating institution in order to maximize the utilization of the server, and by sharing the resource (Resource) to share the data processing cost of the server The Internet Data Center (IDC), which has been directly and centralized in its form, has emerged.

However, as the servers are directly and centralized as described above, indirect costs due to environment parameters, which are not important when they are operated individually, have a large proportion to data processing costs. For example, in the IDC, which must maintain a constant temperature in summer, the constant temperature maintenance cost (= amount of electricity consumed by the air conditioner and power usage fee), which is a representative environmental variable, accounts for more than 15% of the total data processing cost excluding labor costs. If it is possible to reduce the indirect cost consumed to maintain the temperature, the overall data processing cost can be reduced together.

An object of the present invention to solve the above problems is to provide at least two or more data centers or servers distributed in a domestic and overseas region in a coordinated process so as to recognize the equivalence in technical configuration and / or function performance for a specific client's data processing request In response, the data processing corresponding to the data processing request of the client is switched to be processed in a specific data center or server having a low data processing cost, thereby acknowledging equivalence in technical configuration and / or function performance for the predetermined data processing as described above.

The equivalence in technical configuration of at least two or more data centers or servers cooperatively processed through the alliance agreement may vary depending on the manufacturer of hardware and / or software and / or DBMS (DataBase Management System) that make up the data center or server. Although internal data processing methods are different from each other, it means that the data processing technology configuration for performing the data processing requested by the client terminal should be the same.

For example, certain data centers or servers are hardware devices provided by Hewlett-Packard Company in Palo Alto, California, USA, and HP-UX operating systems, and Oracle from Oracle Corporation, Redwood, California, USA. The other data center or server, which is made up of a DBMS and associated with the data center or server, is a hardware device provided by IBM (International Business Machines Corporation) in Armonk, NY, and Microsoft, Redmond, WA. It is composed of Windows operating system and Structured Query Language (SQL) DBMS provided by (Microsoft Corporation), so that the manufacturers of hardware, software, and / or DBMS that make up the data center or server are different and internally process data. Even if this is different, the client terminal If a particular data center, or server to perform the data processing request is a Web server with the D / B, to be acceptable to the equivalence on the technology configuration, and another data center or server is also a web server equipped with a D / B.

To this end, at least two or more data centers or servers linked through an alliance agreement have the same digital content (eg, text content, image content, and sound content) to perform the same data processing. , Multimedia Contents).

For example, each data center or server associated with the web server is equipped with a D / B. When the data center or server streams multimedia content to the client, each data center or server is connected to the client. Equivalence in the performance of the function of streaming multimedia content should be acknowledged.

According to a preferred embodiment of the present invention, the equivalence in technical configuration and / or function performance of the data center or servers is recognized as valid in the process of making an alliance agreement, and only when the validity is recognized.

According to the present invention, if at least two or more data centers or servers are cooperatively processed so as to recognize the equivalence in technical configuration and / or function performance as described above, network switching information and data processing cost calculation information for the data center or server may be obtained. And stored in a predetermined storage medium.

The network switching information stored in the storage medium is information required for a switching server (or relay server) to switch a specific data center or server to the client for data processing, and the network connection information for the data center or server (e.g., A communication protocol, a communication port, a network address (for example, an IP address or a domain name), directory information, and connection parameter information for the client terminal to access a data center or a server. A network switching policy (eg, connecting a direct communication session between the client terminal and the data center or server, or switching server communicating from the relay server to the client terminal and the data center or server) Act as session relay node Data processing capacity information of the data center or server (e.g., processor's processing speed, memory (e.g., random access memory), processor's processing rate delay per unit connection) Memory usage) and network transmission capacity information of the data center or server (e.g., maximum communication line speed of the data center or server, maximum processing speed of each network node), and the like. The data processing capability information and the network processing capability information may be omitted from the network switching information.

The network connection information included in the network switching information is information required for the client terminal or the switching server (or relay server) to connect to a data center or server having a low data processing cost for data processing and to connect a communication session. The switching information includes at least one network connection information for each data center or server.

In addition, the network switching policy included in the network switching information may be configured to route the client terminal to the data center or server in connecting the communication session, or to route the switching server (or relay server) to the client terminal and the data center or the like. As a policy for deciding whether to connect as a relay server between servers, the switching server (or relay server) may have a specific network switching policy fixedly applied, or the specific network switching policy may be dynamically determined at the switching stage. .

For example, if the switching server (or relay server) is interlocked with a domain name server (DNS), the network switching policy preferably switches by routing the client terminal to the data center or server, or the switching server (or If a relay server) is provided in an ISP (Internet Service Proviser), the network switching policy is preferably connected by using the switching server (or relay server) as a relay server between the client terminal and the data center or server. .

In addition, the data processing capacity information and / or network processing capacity information of the data center or server is the data that is switched in the switching server (or relay server) when switching the client terminal to a data center or server of low data processing cost As information for estimating data processing capacity or network processing capacity of a center or a server, a switching server (or relay server) provides the most efficient data processing service to a client terminal through the data processing capacity information and / or network processing capacity information. Be sure to

For example, although the switching server (or relay server) switches the client terminal to a data center or server having a minimum data processing cost according to a data processing request of the client terminal, the switching server (or relay server) is based on the data processing capacity information and / or network processing capacity. When the data center or the server having the minimum data processing cost is inefficient in processing the data, the terminal is switched to the data center or the server having the lowest data processing cost.

The data processing cost calculation information stored in the storage medium is information for a switching server (or relay server) to determine a data center or server having a low data processing cost for data processing requested by the client, and includes at least one fixed information. And cost calculation information and / or variable cost calculation information and / or a cost calculation formula.

The fixed cost calculation information of the data processing cost calculation information is a constant including a constant value which does not change with time among information substituted into the cost calculation formula in calculating the data processing cost of the data center or server. In this case, the value is determined and stored in the storage medium at the cooperation agreement stage of the data center or the server, and is then updated only if the value is changed. For example, a fixed ratio calculation information includes a region where the data center or a server is located or a per unit time and per unit power usage charge used by the data center or server.

In addition, the variable cost calculation information of the data processing cost calculation information is a variable including different values with respect to time among information substituted into the cost calculation formula in calculating the data processing cost of the data center or server. Integer or real number variables are stored at the data center or server alliance agreement stage, and the value of the variable is periodically updated or the data processing cost is calculated in real time. It is characterized by being updated. For example, the power usage used by the data center or server at the present time corresponds to variable cost calculation information.

In addition, the cost calculation formula of the data processing cost calculation information is a formula or function for calculating the data processing cost using the fixed cost calculation information and the variable cost calculation information in calculating the data processing cost of the data center or the server. (Function), the at least one fixed cost calculation information and / or at least one variable cost calculation information and / or at least one fixed cost calculation information and variable cost calculation information for calculating the data processing cost of at least one operator ( For example, a four-dimensional operator, a calculus operator, a logarithm operator, an exponential operator, etc.) and / or at least one or more boundary conditions may be used as a domain of definition.

For example, the power usage fee per unit time and per unit power of the data center or server is 'A', and the power consumption used by the data center or server at the current time is 'B', and the data processing cost is If 'C', the cost calculation formula for calculating the data processing cost is defined as 'A * B = C'.

It is obvious that many and varied, and therefore the cost calculation is also more complicated than the above examples.

According to a preferred embodiment of the present invention, the fixed cost calculation information includes labor cost, depreciation cost, and / or the data per unit time for operating the data center or server in addition to the above-mentioned power usage fee per unit time and unit power. Taxes may be paid to the region or country where the center or server is located, and the variable cost calculation information may be used by the data center or server to process data requested by the client in addition to the current power consumption used as described above. A total process time, a cooling device driving time for maintaining a constant temperature, and a power consumption of the cooling device may be included. Accordingly, the cost calculation formula may include at least one of the fixed cost calculation information and the variable cost calculation information. Data through operators and boundary conditions It takes the form of a complex formula or function to calculate processing costs.

For example, in the case of a streaming service, the data processing time is the same as the playback time of the streamed video content. However, in the case of data processing such as numerical calculation, the data processing time is flexible depending on the computing power of the corresponding data center or server, in which the switching server (or relay server) can simulate lyric or predetermined data calculation and / or statistics. The data processing time is predicted through the processing, and the data processing cost using the variable cost calculation information is calculated.

In this case, the switching server (or relay server) switches to perform the data processing on the video content among the at least two or more server server having a low data processing cost. At this time, the role of the switching server (or relay server) is the video content among the tags (eg, <A HREF=_CONTENT_PROVIDER_> </A>) for processing data on the video content among the web documents provided by the original server to the client. It determines and determines a server having a low data processing cost that actually performs data processing for the assignment and assigns to the tag (for example, _CONTENT_PROVIDER_ = “mms: //lowcost.com/lecture001.wmv”).

In addition, query relaying is performed by the switching server (or relay server) in switching a client requesting data processing to a cheap data center or server that actually performs the data processing requested by the client.
