FIG. 1 is a schematic diagram of a terminal for optimizing a domain of an API server responsive to a call of a specific function according to an embodiment of the present invention, and an API server and a domain name server communicating with the terminal.

1, a terminal 100 is a wireless Internet terminal capable of accessing a network 400, and includes a mobile communication terminal, a notebook, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player) But the present invention is not limited thereto.

The terminal 100 has one or more processors, memory, and one or more modules, programs, or sets of instructions stored in memory to perform a plurality of functions.

More specifically, the terminal 100 includes at least one memory 110 and at least one processor 120 for storing instructions, which instructions enable the processor 120 to perform operations ), And the operations may include requesting data to the API server for server API call and domain optimization and execution of a specific function.

The domain name server 200 converts a domain name received from the terminal 100 into an IP address and returns the converted IP address to a numeric address used by the machine. The domain name server 200 transmits to the terminal 100 the IP address of at least one API server 300 that can access the domain name.

An application programming interface (API) server 300 stores content provided by a contents provider and performs a function of responding to a request for content through the terminal 100. That is, the API server 300 carries out a function of transmitting the content requested from the terminal 100. At least one of the API servers 300 is constructed on the network so that the terminals 100 distributed in various regions can be connected to one domain name.

The network 400 refers to a data communication network for data transmission and information exchange between the terminal 100, the domain name server 200, and the API server 300. The network 400 is an IP network that provides large capacity data transmission / reception services and seamless data services through IP, and can be an IP network structure in which different networks are integrated based on IP. In another aspect, the network 400 may be one of a mobile communication network, a WiBro (Wireless Broadband) network, a HSDPA (High Speed Downlink Packet Access) network, and a satellite communication network, but is not limited thereto.

The terminal 100 may receive data from a plurality of domain name servers 200 and at least one API server 300 connected to the network 400.

The terminal 100 provides an environment for installing various applications and executing installed applications. The user can execute a specific function provided by the application on the terminal 100. [ Such a specific function may be, for example, user authentication or cost settlement, but is not limited thereto.

When the specific function is launched, the terminal 100 queries the domain name server 200 of the IP address of the API server 300 corresponding to the domain previously matched to the specific function. The terminal 100 receives the IP address of the API server 300 corresponding to the domain name previously matched to the specific function from the domain name server 200. [ The terminal 100 accesses the API server 300 using the received IP address. The terminal 100 requests the API server 300 to transmit various data for executing a specific function and receives the corresponding data from the API server 300.

In another aspect, the terminal 100 may include a browser. When a domain name of the API server 300 such as a URL (Uniform Resource Locator) requesting a specific content is input to the browser of the terminal 100, the terminal 100 transmits the domain name of the API server 300 corresponding to the input domain name And queries the domain name server 200 for the IP address. The terminal 100 receives the IP address of the API server 300 corresponding to the input domain name from the domain name server 200. The terminal 100 accesses the API server 300 using the received IP address. The terminal 100 requests the API server 300 to transmit the corresponding content and receives the corresponding content from the API server 300.

Figures 2 and 3 are exemplary block diagrams of a method for domain selection of an API server in response to a call to a particular function in accordance with an embodiment of the present invention.

A method of selecting a domain of an API server that responds to a call of a specific function on a terminal includes the steps of 1) server API call test step S100, 2) domain optimization step S200, and 3) . ≪ / RTI >

The terminal 100 may perform 1) a server API call test step S100 and 2) a domain optimization step S200 for a predetermined time as a preset performance test time.

This performance test can be conducted in multiple circuits.

1) Server API call test step (S100) includes 1-1) requesting IP address transfer to each registered domain name server (S110), 1-2) requesting the API server having the received IP address as a specific function (S120), and 1-3) the terminal receives data for execution of a specific function from the API server (S130). In addition, the performance test may be performed a plurality of times (N times) for each domain name server for a preset time (S140). When the performance test is completed, the domain optimization step S200 may be performed.

2) domain optimization (ranking) step S200 includes a step 2-1) a server API call performance evaluation step S210, and 2-2) a step of prioritizing a plurality of domain name servers based on a performance evaluation result S220).

<Server API call test>

1) The server API call test procedure is explained in more detail.

The terminal 100 may request an IP address to each of a plurality of domain name servers 200 registered in advance. The IP address is the network address information of the API server 300 for the domain matching the specific function.

Each of the plurality of domain name servers 200 may transmit an IP address to the terminal 100 in response to a request from the terminal 100.

However, the present invention is not limited to the case where the terminal 100 receives an IP address from each registered domain name server 200. For example, at least one of the domain name servers 200 may fail to transmit an IP address to the terminal 100 due to various errors, and conversely, the terminal 100 may request at least one of the domain name servers 200 You may not receive an IP address from one.

When the terminal 100 receives the IP address from the domain name server 200, the terminal 100 can call a specific function to the API server 300 having the corresponding IP address. API server 300 may transmit data for execution of a specific function to terminal 100 in response to a call from terminal 100. [

Each time the terminal 100 receives an IP address from a plurality of domain name servers 200, the terminal 100 may call a specific function to the API server 300 having the received IP address as an address.

<Domain optimization step>

2) Domain optimization is explained in more detail.

The terminal 100 can evaluate the server API call performance.

The terminal 100 may repeat the server API call performance evaluation for each of the registered domain name servers 200 for a predetermined time.

The terminal 100 can evaluate the server API call performance based on the communication time required for proceeding with the server API call test step for each domain name server 200 registered. The communication time may vary according to the response speed of the domain name server 200 and the API server 300, respectively. For example, when the response speed of each of the domain name server 200 and the API server 300 is high, the communication time is reduced. On the contrary, when the response speed of any one of the servers is slow, the communication time is long.

The response speed of the domain name server 200 may be determined based on a communication time required for the terminal 100 to receive the IP address from the domain name server 200. [ For example, if the communication time required for the terminal 100 to receive the IP address from the domain name server 200 is short, the terminal 100 evaluates the response speed of the domain name server 200 at a relatively fast response speed. The communication time required for the terminal 100 to receive the IP address from the domain name server 200 is a time for interpreting the domain name received by the domain name server 200 as an IP address, It depends on the time.

The response speed of the API server 300 is determined based on the time taken for data communication between the terminal 100 and the API server 300 and the variation width of time required for the terminal 100 to receive data from the API server 300 Can be determined.

In addition, the terminal 100 may evaluate the server API call performance based on the time out rate that occurs while proceeding with the server API call step for each domain name server 200 registered.

Hereinafter, the server API call performance evaluation will be described in more detail.

The terminal 100 repeatedly calculates a standard deviation of the communication time and an average value of the communication time while repeating the server API call test step for each of the registered domain name servers 200. [

The standard deviation of the communication time indicates the stability of the response speed of the domain name server 200 and the API server 300 according to the server API call performance. Therefore, as the stability of response speed increases, the number of standard deviation of communication time decreases. The average value of the communication time indicates the speed of response of the domain name server 200 and the API server 300 according to the server API call performance. Therefore, the faster the response speed, the lower the average communication time.

In addition, when the terminal 100 repeatedly performs a server API call test step for each of the registered domain name servers 200 and a timeout occurs, the terminal 100 can classify the generated timeout according to the cause. That is, the terminal 100 can determine whether the generated timeout is a timeout due to a terminal-network interval error or a timeout due to a network-server (domain name server, API server) interval error.

The timeout may occur due to an error of the terminal 100 and the network 400 (terminal-network interval error). The timeout may also occur due to an error (network-server interval error) between the network 400 and the domain name server 200 or between the network 400 and the API server 300.

If the network connection of the terminal 100 is canceled, the network 400 is disconnected, the Internet connection is terminated, the network connection authentication is canceled or failed, For example, when a certificate for an application has an error. Such an error may occur due to a problem in the network connection environment of the terminal 100 irrespective of the performance of the domain name server 200 or the API server 300.

The network-server interval error may be caused by a malfunction of the URL matched to a specific function, a failure to find a host, a connection to a host, an overload of the domain name server 200, too many redirects The terminal 100 can not access the domain name server 200 or the API server 300 for a predetermined period of time when resources are used or redirected to a non-existent location, And the like. Such an error may occur between the network 400 and the domain name server 200 or between the network 400 and the API server 300 irrespective of the performance of the terminal 100.

When a timeout occurs due to a cause of a network-server interval error, the terminal 100 uses the timeout as a statistical value for API call performance evaluation. In contrast, when the terminal 100 generates a timeout due to a terminal-network interval error, the terminal 100 does not use the timeout as a statistical value for evaluating API call performance.

By not using the timeout due to the terminal-network interval error as a statistical value, the reliability of API call performance evaluation can be improved.

The reason for this is that, due to the nature of the mobile environment of the terminal 100, the process of frequently disconnecting and reconnecting the network connection may be repeated. Thus, a timeout frequently occurs due to an error in the terminal-network interval, which is not related to the performance and stability of the domain name server 200 or the API server 300. In addition, since there are many variables according to the environment of the user terminal 100, statistics on whether or not the terminal 100 and the network 400 are connected are meaningless.

The terminal 100 may assign a predetermined weight to each of the standard deviation of the communication time according to the server API call, the average value of the communication time, and the timeout ratio according to the network-server interval error to finally calculate the performance result of the server API call .

More specifically, the terminal 100 performs a performance evaluation of a server API call while conducting a plurality of circuit server API call tests for each of a plurality of registered domain name servers 200.

A plurality of circuit server API calls are made to one domain name server 300, and a timeout ratio, a standard deviation of communication time, and an average value of communication time caused by network-server interval errors can be calculated.

In addition, the terminal 100 may add a predetermined weight to the standard deviation of the communication time, the average value of the communication time, and the occurrence rate of the timeout.

For example, the terminal 100 may generate a second performance result by multiplying the calculated timeout ratio by a first weight to produce a first performance result, multiplying a standard deviation of the calculated communication time by a second weight, And multiplying the average value of the communication times by the third weight to generate a third performance result.

In addition, the terminal 100 may sum up the first through third performance results to generate final performance results.

In addition, the terminal 100 may compare the final performance results of the respective domain name servers 200, and prioritize the domain name servers 300 in order of decreasing final performance results. That is, the lower the final performance result, the higher the priority.

On the other hand, the first weight is higher than the second weight and the second weight is higher than the third weight. That is, the terminal 100 considers the standard deviation of the communication time and the ratio of the timeout to the average value as a more important evaluation factor in evaluating the server API call performance.

The terminal 100 considers the standard deviation of the communication time to the average value of the communication time as a more important evaluation factor in evaluating the server API call performance. This is because when the user uses a particular function, he or she empirically recognizes the time it takes to execute the function. That is, even if the execution speed of the specific function is fast, the user is likely to judge that the service is abnormal if the speed is slowed down under a specific situation.

In another aspect, when the terminal 100 proceeds to make a plurality of circuit server API calls for each of the plurality of registered domain name servers 200 and makes a final server API call, the terminal 100 generates a timeout due to a network- The priority of the domain name server 200 can be set to the lowest ranking. This is because, if a timeout occurs in the last server API call, it is probable that such a timeout will continue until the actual user invokes a particular function.

&Lt; User server API calling step >

4 is an exemplary block diagram of a server API call step of a user according to an embodiment of the present invention.

When the terminal 100 receives a request to execute a specific function from the user, that is, when the terminal 100 receives a server API call request from the user (S310), the terminal 100 registers the IP address of the domain matched with the specific function The IP address for the corresponding domain can be queried to the domain name server corresponding to the highest ranking among the plurality of domain name servers 200 in operation S320.

When the terminal 100 receives an IP address from the domain name server having the highest ranking, the terminal 100 calls a specific function to the API server 300 having the corresponding IP address.

During the server API call step of the user, the terminal 100 may measure the server API call performance for the domain name server having the highest ranking (S330).

The terminal can measure the server API call performance and determine whether the server API call performance satisfies the criteria (S340).

For example, if the server API call performance for a top-ranked domain name server is measured and the communication time does not meet the criteria (for example, if the response time is slow or a timeout occurs) 100) can continue the user's server API call using the domain name server of the next rank (S350).

As a result of measuring the server API call performance for the domain name server having the highest ranking, the embodiment performs the connection retry process for the best-ranked domain name server when the response speed does not satisfy the criterion or the timeout occurs I never do that. This is because it is unlikely that smooth service will be provided through the retry process. Therefore, the embodiment maintains the quality of the API call performance by directly proceeding with the server API call to the domain server of the next rank that is likely to be connected and a stable response speed is expected.
