Description

TECHNICAL FIELD [0001] The present invention relates to a service-oriented architecture protocol dynamic configuration system and a method thereof,

The present invention relates to service-oriented architecture protocol configuration technology, and more particularly, to service-oriented architecture of a military communication network, in order to provide smooth service in a tactical communication network having various network characteristics, A protocol dynamic configuration system using service binding, and a method thereof.

Service-oriented architecture is a methodology that defines the software functions used for business processing in the construction of a large-scale computer system as a service, and constructs the whole system by linking the corresponding services on the network.

The methodology is a method designed to quickly apply business process changes to the system. The component of the system processes the input values of the service user and the service user performing the service request for the use of the specific service, A service provider providing the result value, and a service registry storing descriptive information about the service.

The service provider registers the contents of the service provided by the service provider in the service registry, and the service user searches for and uses the required service in the service registry.

The protocol structure used in the service-oriented architecture currently uses an XML-based protocol that is highly readable and easy to develop in the private sector, but in principle the service-oriented architecture is independent of the specific technology and / or protocol. However, the configuration protocol of the service-oriented architecture requires that the network performance of the network be configured as an acceptable protocol so that normal service can be provided.

In the current private sector, we use a fixed, XML (eXtensible Markup Language) based service oriented protocol without any special restriction by using a stable and large bandwidth network. It is not a consideration.

However, the military communication network has varying network characteristics according to the environmental factors such as the size of the unit, operational environment, terrain, and climate. In order to provide continuous service, it is necessary to reflect network characteristics in determining the protocol configuration and service providing method .

1 is a block diagram of a service-oriented architecture protocol dynamic configuration system 1 that reflects network characteristics according to an embodiment of the present invention. Referring to FIG. 1, a service-oriented architecture protocol dynamic configuration system 1 includes a user terminal 101 that performs profile setting and / or manual network setting, receives profile setting and / A service terminal 100 that performs service registration and / or search that reflects characteristics of the network, and a military communication network 10 that generates network characteristic monitoring information according to network manual setting information.

The service terminal 100 includes a service binding profile management unit 110, a service application unit 120, a network property collection unit 130, a protocol dynamic configuration unit 140, and the like.

The service binding profile management unit 110 manages mapping information between a service-oriented application protocol and a transport protocol that can be mapped and used in a network characteristic.

The service application unit 120 refers to an upper application that processes a service request and / or a response. The service application unit 120 uses the protocol matching unit 141 and the application socket 141-1 of the protocol dynamic configuration unit 140, Will determine which service-oriented application protocol 142 to use for the selected service.

The network characteristic collecting unit 130 collects network characteristic information on which the service terminal 100 is located and transmits the information to the protocol dynamic configuration unit 140.

The protocol dynamic configuration unit 140 includes a protocol matching unit 141, a service-oriented application protocol 142, and a transmission protocol 143. These components will be described as follows.

The protocol matching unit 141 performs a service-oriented application protocol and a transmission protocol binding determined based on the profile information managed by the service binding profile management unit 110 and the network characteristic information collected by the network property collecting unit 130, As a result of this execution, a service socket is generated.

The service socket 141-2 is an interface to which the service-oriented application protocol 142 and the transport protocol 143 are bound and can use a binding protocol combination using a unique identifier of the service socket.

The application socket 141-1 refers to an interworking interface between the service application 120 and the protocol matching unit 141 and transmits a parameter required for service request and / or response transmission in the service application 120 using the interface And the protocol configuration for transmitting the parameter is performed by the protocol matching unit 141. FIG.

The service-oriented application protocol 142 refers to a protocol that constitutes a service request and / or a response message. Examples of protocols currently used in service-oriented architectures include Simple Object Access Protocol (OAP), Constrained Applilcation Protocol (COAP), Representational State Transfer (REST), and naive XML (eXtensible Markup Language).

The transmission protocol 143 refers to a transmission protocol for transmission of a service-oriented application protocol, and is an example of a transmission protocol such as a CP (Transmission Control Protocol), a UDP (User Datagram Protocol) and a WTCP (Wireless Transmission Control Protocol).

1, the service binding profile managed by the service binding profile management unit 110 shown in FIG. 1 is set by the user at the time of installing the first service terminal 100, and the corresponding information is included in the network plan, You must have the same information. All terminals in the network through the service binding profile unique identifier perform the same protocol configuration according to the identifier.

The profile configured in the service binding profile is composed of a combination of a service-oriented application protocol and a transmission protocol used according to network characteristics and network characteristics, and is shared by service terminals of all networks through a unique identifier that identifies the corresponding service binding profile .

For example, Table 1 (Example of service binding profile) can use SOAP protocol and TCP protocol when bandwidth is guaranteed over 4Mbps and network delay is below 100 ms. Table 1 shows the following.

profile
Identifier at least
Bandwidth Maximum delay Service Oriented
application
protocol send
protocol Explanation A 4 Mbps 100 ms SOAP TCP B 256 Kbps 100 ms REST TCP Using REST to work with small bandwidth C 265 Kbps 2000 ms REST UDP UDP is used because it is difficult to maintain the TCP connection if the delay time is large.

For a service terminal that guarantees a bandwidth of 256Kbps ~ 4Mbps, it can use REST with low bandwidth burden for service oriented application protocol and TCP protocol which can guarantee reliability when network delay is below 100ms.

However, since the TCP connection management is difficult to perform when the network delay is 100 ms to 2000 ms, the service binding profile for using the UDP protocol is shown.

The network characteristics collecting unit 130 shown in FIG. 1 manages the network characteristics measured in the military communication network 10 and / or the network characteristics measured when sending / receiving a packet related to a service. If the network characteristics can not be measured or if there is no meaning as a network characteristic value due to a large deviation or if the setting is required according to the user's intention, the network characteristics will be managed according to the manual setting by the user. (140).

The protocol dynamic configuration unit 140 shown in FIG. 1 is configured of a transmission protocol 143, a service-oriented application protocol 142, and a protocol matching unit 141. The protocol dynamic configuration unit 140 includes information specified in a service binding profile, Based application protocol and a transport protocol to be used based on the network property value of the service-oriented application.

The corresponding information is transmitted to the protocol matching unit 141 to perform service binding of the selected service-oriented application protocol 142 and the transmission protocol 143, and generates a service socket as a result of the service binding.

The generated service socket has a unique identifier, and then the protocol configuration is performed using the unique identifier of the corresponding service socket. In this case, the protocol configuration means a combination of a service-oriented application protocol and a transmission protocol.

For example, if the unique identifier of the service socket generated by the combination of REST and UDP is "1", the packet transmitted / received using the subsequent service socket "1" is encapsulated / decapsulated as a service parameter using REST And the generated REST protocol is transmitted / received using the UDP protocol.

The application socket 141-1 provided for interworking with the service application unit 120 in the protocol matching unit 141 is connected to the service application unit 120 and the protocol matcher 141, It is an interface that enables exchange of parameter information. The interface can be provided in API (Application Programming Interface) form.

The service application unit 120 can be designed and implemented independently of the lower protocol when exchanging parameters for a service request and a response using the application socket 141-1. Thereafter, even when a new service-oriented application protocol and a transmission protocol are applied, .

Therefore, even when a new service-oriented protocol or transmission protocol is required, it is not necessary to change or modify the existing service application, and it becomes possible to design and implement a service-oriented architecture that can be applied without interruption of the existing service.

The service-oriented application protocol and the transport protocol perform the encapsulation and decapsulation functions of the corresponding protocols, and they can be added, deleted and managed in the form of modules and libraries.

FIG. 2 is a sequence diagram illustrating a service registration and / or search process that reflects network characteristics according to an exemplary embodiment of the present invention. In particular, FIG. 2 is a flowchart illustrating a service registration and search procedure reflecting network characteristics performed between a service provider, a service user, and a service registry.

Referring to FIG. 2, the service provider 211 has to register the service provided by the corresponding service terminal in the service registry 220, and the service registration profile message includes service binding profile information available from the corresponding service terminal. Accordingly, a service registry database 230 for storing service registry information is configured.

For the sake of understanding, the term "service terminal" refers to a terminal of a service provider and / or a service user for service management and / or processing provided by a service oriented architecture.

The service registry 220, which receives the service registration request from the first service provider 211 and / or the second service provider 212, registers the service provider, service type, and service binding profile information in the database, And notifies the service provider that the registration has been performed (S201, S202, S203, S204, S205, S206).

When a service use event occurs in the service user 101, a service search request is transmitted to the service registry 220 for searching for a service provider providing the service in operation S207. The Service Discovery Request message should contain the service binding profile information available to the service user.

The service registry 220 receiving the service search request preferentially searches for a service provider that supports the service type requested by the service user 101. After that, a service binding profile provided by the service provider and a service binding profile provided by the service requestor are compared and analyzed to select a service provider providing the optimal service binding profile. The information is transmitted to the service user 101 through the service search request response. The service search request response includes not only the optimal service binding profile information but also the service binding profile information used by the corresponding service provider, So that the change can be performed (S208, S209-1).

The service provider 211, which is searched in response to the service search request in the service registry 220, provides the service user and the service binding profile information to be used and the service binding profile information provided by the service user through the service use request message, And a profile change function according to a change in network environment during service execution is also made possible (S209-2).

At this time, the service registry 220 and the service registry database 230 are configured in a separate server, and must be able to communicate with the service provider 211 and the service user 101 that provide service terminal functions on the network.

3 is a sequence diagram illustrating a process of changing a service binding profile at the time of changing network characteristics during service execution according to an embodiment of the present invention.

Referring to FIG. 3, a service related message exchange between the service provider 211 and the service user 101 is performed after performing the protocol negotiation and the arbitration function performed by the service registry (220 in FIG. 2) (S301).

When a change value of the network characteristic is transferred from the network property collecting unit (130 in FIG. 1) to the protocol dynamic configuration unit (140 in FIG. 1) during service execution, an optimal service binding profile usable according to the network characteristic can be used A service binding profile change procedure is performed.

This service binding profile changing procedure is performed between the service user 211 and the service provider 101 and performs a service binding profile changing procedure using a service binding profile change request message and a service binding profile change request response message (S303, S304).

At this time, the service binding profile is based on the service binding profile information 311 and 312 of the service user and the service provider collected in the service discovery procedure, selects an optimal service binding profile among the service binding profiles available in both the service user and the provider, The binding profile changing function is performed (S302).

After the successful change of the service binding profile, the service can be continuously provided using the changed service binding profile (S305).

This procedure is performed first on the side of the service user or the service provider who detects the change of the network status.

Of course, the databases 311 and 312 are configured to store profile information of the service user and the service provider.
