The present invention relates to a method and system for providing a blog service using peer-to-peer communication (P2P: Peer to Peer, hereinafter referred to as 'P2P'). More specifically, all blog client terminals using the blog service using the JXTA blog application running on the JXTA platform serve as a blog server terminal providing a blog service. It also relates to a method and system for providing a blog service without using a blog server.

As computer, electronic, and communication technologies have made rapid strides, the use of the Internet by the public has become commonplace, and the number of Internet users who use various functions provided by the Internet is steadily increasing. Among them, the Internet blogging service has become a tool for Internet users to enjoy leisure time using a computer.

Here, blog is an abbreviation of Weblog, which is a kind of Internet diary function that writes what the individual thought and felt through the web as a representative function. However, this describes only one of the many uses of the blog, and the blog may be a notepad, sketchbook, scrapbook, essay book, autobiography, photo book or newspaper, depending on the purpose of use.

Therefore, blog users talk about their interests and hobbies with others who access their blogs, express their thoughts and feelings, and share their daily lives with friends and family in various ways, including text and images. Can be shared together.

1 is a block diagram schematically illustrating a typical Internet blog service system.

A typical internet blog service system includes first user terminals 110 to Nth user terminals 118, the Internet 120, and a blog server 130.

The first user terminal 110 to the Nth user terminal 118 access the blog server 130 through the Internet 120 and subscribe to the blog service, and then use the blog service provided by the blog server 130 to blog. These are desktop computers and laptop computers that can be accessed by blogs of individuals who have subscribed to the service.

The Internet 120 includes various services existing in the TCP / IP protocol and its upper layers, namely, Hypertext Transfer Protocol (HTTP), Telnet, File Transfer Protocol (FTP), Domain Name Server (DNS), and Simple Mail Transfer Protocol (SMTP). , A global open computer network architecture that provides Simple Network Management Protocol (SNTP), Network File Service (NFS), and Network Information Service (NIS).

The blog server 130 is implemented as a general network server and stores a blog created and registered by a plurality of subscribers who have subscribed to a blog service, so that the blog server 130 may request a plurality of terminals 110 to 118 connected through the Internet 120. Accordingly, the blog service provides a blog service that provides a blog of subscribers. Network servers are computer systems and computer software that are typically connected to subordinate devices capable of communicating with other network servers through a computer network, such as a private intranet or the Internet, to receive and perform a task request and provide a result of the task. (Network server program).

In a state in which the first user terminal 110 to the N th user terminal 118 subscribe to the blog service, the first user terminal 110 accesses the blog server 130 through the Internet 120 and the blog server 130. The first user terminal 110 stored in the terminal receives the blog data of the individual to be provided. In addition, the first user terminal 110 browses the blog of the individual, if necessary, writes or registers data such as photos, music, and videos. That is, the blog server 130 stores a blog of an individual who has subscribed to a blog service and provides blog data at the request of a plurality of user terminals or is changed and registered by an individual who has subscribed to a blog or a user of a user terminal. This function updates and saves the contents of the blog.

Therefore, in the conventional blog service, as described above, the role of the blog server 130 is most important, and personal blogs registered by blog service subscriber individuals are transmitted through the blog server 130 at the request of a plurality of user terminals. For this reason, if the blog server 130 does not perform its function due to failure or repair, or the like, user terminals using the blog service through the blog server 130 may not be provided with the blog service.

On the other hand, since the typical blog service uses a typical server and client network, the role of the server is emphasized in a server-centric manner. Therefore, as the number of clients requesting a blog service to the server increases, the server and client methods have a disadvantage in that traffic is concentrated on the server. That is, as the number of user terminals accessing the blog server 130 and using the blog service increases, the load, bandwidth, storage capacity, etc. requested by the blog server 130 increase, and in the serious case, the user terminal is the blog server 130. Sometimes you can't access. Attempts have been made to address the shortcomings of these server and client methods.

P2P is a person-to-person file sharing technology and behavior on the Internet. Peer-to-peer is a technology and behavior that makes symmetrical interactions happening on the network, allowing all computers connected to the network to share data and peripherals in the same peer position.

Systems for P2P can be classified into three types: central control system, hierarchical system, and distributed system. Here, the central control system has a server in the center, and operates in a cooperative relationship among a plurality of peers. In other words, the peer attempts to connect to the central server, obtains information on which peer the data it is looking for, and downloads the data from the target peer. The system provided by Napster is a representative example of a central control system. The hierarchical system is a system in which all or part of the control authority is delegated to the lower controller. In a hierarchical system, each peer forms a group around a controller above it, and all peers in that group are controlled by the controllers in that group. In addition, a distributed system is a system that guarantees free connection between all peers without control. In other words, in a distributed system, communication between peers is complementary, so that each peer can receive data through another peer even if one peer is disconnected. Freenet and Gnutella are examples of distributed systems.

However, the blog service is still centered on a specific server such as the blog server 130 on a server-client network. As described above, the server and client type blog services can easily reach a situation in which service usage is easily interrupted when a service user's request for a specific server is congested and, in serious cases, the service can be stopped. Accordingly, the server and client type blog services have inherent irrationalities and inconveniences that many service users cannot use the blog service due to the failure of the server providing the blog service. In addition, Internet users who were unable to use an external blog server due to the use of an intranet without an Internet connection or due to the installation of a firewall (Fire Wall) could not use the blog service by a server and a client method.

In order to solve this problem, the present invention does not use a blog server by using a JXTA blog application running on the JXTA platform, and all blog client terminals using the blog service also serve as a blog server terminal providing a blog service. The purpose is to provide a method and system for providing a blog service.

In order to achieve the above object, according to the first object of the present invention, a plurality of peers that log in to a shared service group using a JXTA blog application (Juxtapose Blog Application) to provide a blog service or request a blog service ( A method for receiving a blog service in a system including a JXTA P2P network that performs peer-to-peer (P2P) (hereinafter referred to as P2P) using peer and JXTA protocols, (a) Propagating a Blog Query Message to multiple peers in the shared service group; (b) confirming whether to receive a Blog Response Message from one or more of the plurality of peers in the shared service group; (c) generating a blog list by using the received blog response message when the blog response message is received as a result of the checking in step (b); (d) selecting one of the blogs from the list of blogs and connecting to the blog server peer by sending a Blog Service Request Message to a blog server peer that has created one blog; And (e) receiving a blog from a blog server peer and using a blog service. The method provides a method of performing a blog service as a blog client peer using P2P.

In addition, according to a second object of the present invention, a plurality of peers and JXTAs that provide a blog service or request a blog service by logging in to a shared service group using a JXTA blog application. A method of providing a blog service in a system including a JXTA P2P network that performs peer-to-peer (P2P) (hereinafter referred to as P2P) using a protocol (Juxtapose Protocol), the method comprising: (a) a shared service; Checking whether a Blog Query Message is received from any one or more peers of the plurality of peers in the group; (b) if the blog query message is received as a result of the checking in step (a), transmitting a blog response message to the peer that sent the blog query message; (c) checking whether a blog service request message is received from a peer receiving the blog response message; And (d) providing a blog service to a peer that has sent the blog service request message when the blog service request message is received in step (c) as a blog server peer using P2P. Provides a way to run a blog service.

According to a third object of the present invention, in a system for providing a blog service according to a blog service request, a blog client peer (Log In) is executed by logging in to a shared service group by executing a JXTA blog application. A number of peers conducting blogs as Blog Client Peer and Blog Server Peer; And discovery services, peer information services, pipe services, resolver services, endpoint routing services, rendezvous services, and peers using JXTA protocol (Juxtapose Protocol). Provides a blog service providing system using a peer-to-peer, including a JXTA P2P network that provides peer-to-peer services for peer-to-peer communication (P2P: peer to peer, P2P) including a group service as a peer. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

FIG. 2 is a block diagram schematically illustrating a blog service providing system using peer-to-peer communication (P2P: Peer to Peer) according to a preferred embodiment of the present invention.

Blog service providing system using P2P according to a preferred embodiment of the present invention is the first peer (210), the second peer (212), the third peer (214), the N-1 peer (216), N peer 218 and JXTA P2P network 220.

The first peer 210 to the Nth peer 218 include peers on any type of network capable of connecting to the Internet or an intranet. That is, in the present invention, each peer is not limited to a user terminal or a server-class terminal such as a desktop computer or a notebook computer that can access the Internet or an intranet, but a code division multiple access (CDMA) 2000 system, a wideband CDMA (WCDMA), and a portable terminal. A mobile communication terminal that accesses the Internet using a wireless Internet service using a mobile communication system such as an Internet system (HPi: High Speed Potable Internet System or WiBro: Wireless Broadband Internet System) or a wireless local area network. (Mobile Communications Terminal), Personal Digital Assistants (PDAs), and the like.

A peer for using the blog service may exist in a plurality of terminals, such as the first peer 210 to the N-th peer 218 illustrated in FIG. 2. The first peer 210 and the second peer 212 will be described mainly.

In addition, the first peer 210 and the second peer 212 is a network terminal that performs a blog service in a peer-to-peer manner, and may be a blog server peer serving as a server that provides a blog service. It may be a blog client peer serving as a client using the service. That is, the first peer 210 and the second peer 212 may perform a blog service as a blog server peer and a blog client peer.

In the present invention, the blog client peer logs in to the shared service peer group and propagates a discovery message within the shared service peer group to detect all peers belonging to the group, and a peer information message. After receiving information about a peer by sending a message, the blog query message is propagated to all peers of the shared service peer group, and when a blog response message is received from one or more peers, the received blog The blog list is generated by using the response message, and the blog service is selected by selecting any blog from the blog list.

In addition, in the present invention, the blog server peer is a server that provides a blog by logging in to the shared service peer group, and when receiving a blog query message from any one or more peers among all peers belonging to the shared service peer group, When you send a blog response message to a peer and receive a blog service request message from the peer that received the blog response message, you form a blog service peer group consisting of the peers that sent the blog service request message, and then all the peers in the blog service peer group. Provide a blog service.

In the present invention, the blog query message is a message propagated to all peers in the blog service peer group, and includes a query for searching for a blog provided by the blog server peer. Here, the query refers to a search condition for searching for data according to the requested instructions. In addition, the blog response message is a message generated by the peer that has received the aforementioned blog query message in the blog service peer group and sent to the peer that propagated the blog query message. The blog response message indicates whether the blog service is provided. Include a response. In addition, the blog service request message is a message transmitted by a peer that has received the above-described blog response message to a peer that provides a selected blog according to a user's selection. The blog service request message receives a blog of an individual stored in the blog server by accessing the blog server. To request a blog service.

In the present invention, the first peer 210 and the second peer 212 use the JXTA blog application to serve as the above-described blog client peer and blog server peer. That is, all peers equipped with and run the JXTA blog application can perform both the role of a blog client peer and a blog server peer according to a predetermined algorithm of the JXTA blog application. Therefore, according to the present invention, a specific blog server for providing a blog service is installed and the blog server is not subordinate to the blog server under the control of the blog server, but all peers provide the blog service as independent entities. It is available. In the present invention, the JXTA blog application is an application program running on the JXTA platform. In the JXTA application, an algorithm for allowing each peer to act as a blog client peer and a blog server peer is defined.

Here, JXTA is a next-generation P2P development platform for developing P2P services that provide distributed search, file sharing, and collaboration services while communicating with each other, unlike many existing client and server systems. Standard protocols and reference libraries that can address the overall requirements of a P2P domain so that you can focus on implementing collaborative applications rather than P2P's own technology, avoiding the uniqueness and specificity of each solution. ) Is publicly available.

The JXTA P2P network 220 is a network that communicates using the JXTA protocol, a discovery service that provides a mechanism to discover other peer resources, and a message to obtain status information of a peer. Peer information service to query through, Pipe service to provide virtual communication channel connecting endpoints on P2P network, Send message to peer for information processing after peer is discovered A resolver service that receives the message containing the result from the peer, an endpoint routing service that forwards messages sent and received between peers along the path, and propagates messages between peers using a Rendezvous peer Rendezvous service, peer group service for splitting P2P network, etc. are performed by peers in JXTA P2P network 220. .

In the present invention, even when a specific communication protocol cannot be connected to a specific external server by a firewall, a peer inside the firewall can be utilized as a blog client and a blog server using the JXTA protocol. In addition, as the network grows in size, the number of peers belonging to the network increases, and a mechanism for delivering messages between numerous peers is required. Thus, the JXTA P2P network 220 preferably includes a rendezvous peer (not shown) to perform blog services with a blog client peer or blog server peer inside the firewall. Here, the rendezvous peer is a peer that delivers messages transmitted and received between peers and peers, and provides a mechanism for relaying messages between peers and multiple peers or remote peers.

The blog service providing system according to an exemplary embodiment of the present invention may further include a separate authentication server for providing a blog service by the blog server and providing an authentication process for the blog client to receive the blog service.

3 is a flowchart illustrating a method of performing a blog service as a blog client peer using P2P according to a preferred embodiment of the present invention.

In the blog service providing system using P2P configured as shown in FIG. 2, the first peer 210 and the second peer 212 having the JXTA blog application execute the JXTA blog application to perform a blog service. According to the present invention, as described with reference to FIG. 2, the first peer 210 and the second peer 212 may perform both a role of a blog client peer and a blog server peer of a blog service. For example, assume that the first peer 210 plays a role as a blog client peer and the second peer 212 plays a role as a blog server.

The first peer 210 executes the provided JXTA blog application (S310) and logs in to the shared service peer group (S320). In the present invention, the shared service peer group is a peer group for a shared service using P2P formed by a peer group service provided in the JXTA P2P network 220. When the first peer 210 and the second peer 212 execute the JXTA blog application, they log in to the shared service peer group through a predetermined authentication procedure. Since P2P is not dependent on a specific server and each peer has an equal status, in order to use a series of services, the P2P network needs to be divided into parts. This can also be seen as the specification of a region for propagating messages and receiving replies.

The first peer 210 logged into the shared service peer group propagates discovery messages within the shared service peer group to detect all peers belonging to the shared service peer group, that is, the second peer 212 in FIG. After transmitting information about the second peer 212 to obtain a blog query message to the second peer (212) (S330).

The first peer 210 that sent the blog query message receives the blog response message in response to the blog query message from one or more peers (second peer 212 in FIG. 2) of all peers belonging to the shared service peer group. Check whether or not (S340).

When the first peer 210 receives the blog response message as a result of checking in step S340, the first peer 210 generates a blog list using the received blog response message and displays the generated blog list on the screen provided using the JXTA blog application. Output it (S350). Here, the first peer 210 may continue to receive the blog response message, and accordingly, it is preferable to update the blog list.

The first peer 210 that outputs the blog response selects one blog among the blogs listed in the blog list according to a user's selection and creates the blog, that is, the peer that has sent the blog response message (see FIG. 2 peer 212 to request a blog service by sending a blog service request message (S360).

The first peer 210 requesting a blog service uses the blog service by reading blog contents provided by a blog server peer (second peer 212 in FIG. 2) or registering text, images, and media data when necessary (S370). ).

4 is a flowchart illustrating a method of performing a blog service as a blog server peer using P2P according to a preferred embodiment of the present invention.

As described above, the first peer 210 and the second peer 212 may serve as both a blog client peer and a blog server peer of the blog service, but the first peer 210 will be described below for convenience of description. ) Acts as a blog server peer and the second peer 212 acts as a blog client peer.

Preferably, the first peer 210 stores blog data generated by a user of the first peer 210 in advance, and the first peer 210 executes a JXTA blog application to log in to the shared service peer group. Since steps S410 to S420 are the same as steps S310 to S320 described with reference to FIG. 3, a detailed description thereof will be omitted.

The first peer 210 checks whether a blog query message is received from at least one peer (second peer 212 in FIG. 2) among all peers belonging to the shared service peer group (S440).

When the first peer 210 receives the blog query message as a result of checking in step S440, the first peer 210 transmits a blog response message to the peer that sent the blog query message (S450). The first peer 210 that has transmitted the blog response message checks whether a blog service request message is received from the peer that has received the blog response message (S460).

When the first peer 210 receives the blog service request message as a result of checking in step S460, the first peer 210 transmits blog data to the second peer 212 that requested the blog service to serve as a blog server for providing a blog service. (S480). In addition, when new content is registered by the second peer 212, the stored blog data is updated and the updated new blog data is provided to the second peer 212.

The above description is merely illustrative of the technical idea of the present invention, and those skilled in the art to which the present invention pertains may make various modifications and changes without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within the equivalent scope should be interpreted as being included in the scope of the present invention.

As described above, according to the present invention, since it is not necessary to add a server for providing a blog service by providing a blog service in a P2P manner using the publicly available JXTA platform, a space for implementing a blog service is In addition to avoiding the economic constraints, the server for the blog service is not necessary, so that problems such as the blog service interruption caused by the server problem can be solved to provide a blog service that is not dependent on a specific server.                     

In addition, by managing blog data in a personal terminal that can be installed JXTA platform, it is easy to create and modify a blog, there is an advantage that there is almost no limit of the capacity of blog data.

In addition, the blog service can be used or provided in a network using an intranet that is not connected to the Internet, or even in a network that is connected to the Internet but has a firewall installed so that a connection with a specific server is not possible.
