Description

Object transfer system and method

The invention is an object delivery system and method, in particular to a resource sharing transmission scheme based on a community network architecture.

With the development of network information, the general information transfer method used on the Internet is usually under the server-client master-slave architecture, such as the use of Microsoft's regional network sharing method - network neighborhood is Architecture-based, other common e-mail (email), file transfer protocol (FTP), web upload and download (http), etc., are applied under the server-client architecture. However, in such a mode, there will inevitably be a need to provide a large amount of bandwidth resources or storage resources, such as sharing photos through a website. At this time, the provider (server side) needs to provide sufficient bandwidth and sufficient storage at the same time. Space, and other computer resources such as user authentication calculations are required to achieve the purpose of rapid information dissemination.

In recent years, a peer-to-peer transfer protocol has been developed, which is a download mode of BitTorrent (BT). Users are connected to each other through software that is transmitted through a point-to-point file. Each user is downloading. At the same time, it also provides uploading services for related files for other users. Since conferences are established between users, the server does not need to provide space for file storage and bandwidth, which can effectively reduce the server load. . In fact, such peer-to-peer transmission is a bandwidth resource sharing network in cloud computing. This type of network has different ways of calculating the transmission behavior according to the indexing method of the target object, and has a different performance. How to use it.

At present, the common point-to-point transmission method uses keyword search for the target object index, or uses a web page providing a list to propagate the target object number. This method is extremely inconvenient for users of unknown keywords. If the target object is addressed by using the bit stream download method, and the software architecture is called a seed, the seed point circulation speed is quite slow, which does not meet the rapid dissemination of information. Claim.

The disclosure discloses an object delivery system and related delivery method under the community, which mainly operates in a social network virtual space that needs to be authenticated by a user, and users can establish each other through community activities. Contact, such as subscribing to each other's message content, setting up friends with each other, grouping according to interests or system initiative, and transferring files and messages with the concept of peer-to-peer (P2P) sharing, in addition to saving bandwidth resources and expanding Sharing possibilities to storage space and computing power.

The disclosure discloses that the object delivery system operating in the network virtual community includes a plurality of users who have been logged in, and each user computer system is located at each endpoint on the network, and the system includes a user responsible for managing each user. Community server for account, profile, and group behavior. The system may further include another directory server that is responsible for managing the objects passed within the community and the cache points of the objects.

According to an implementation manner, the method for transferring objects in the virtual community of the network includes first setting a shared object by a shared or recommended initiator (one of the community users), and then transmitting the information of the object to the next The user of the order, the friend of the lower level can be a friend set by the initiator, a friend of the system match, or a member of the same group.

The lower-level users can receive the information and then perform the download. The download method can be Obtained directly from the initiator's computer system, or peer-to-peer download by the cache node of the object in the community, wherein the user having the specific object can selectively set the user-side computer system as a cache node. As one of the download nodes of the user who needs to download, thereby the transfer of the object can be accelerated.

Moreover, the directory server can selectively set up a directory server, and the directory server is a server for collecting user activities in the community, including backing up the shared objects, where the objects of each node can be recorded. Or / with the information traffic server, the directory server can establish a download list of various objects according to the status of each node.

The above directory server is also used to collect file backups of various objects. Since each user's computer system may not always be in a networked state, or each user is not a normal login community, a specific cache node may be caused. Unstable, affecting the sharing of objects, so you can use the directory server to back up various object resources.

An object delivery system and related delivery method under the community, according to an embodiment, the object delivery system is mainly operated in a social network virtual space that needs to be authenticated by a user, and the network virtual community has a plurality of Log in to the user, especially through a web page provided by a community server or an interface provided by a proprietary interface software. When the login user logs into the community server, the system enters the virtual community, and the system can actively perform mediation based on the basic information filled in by the user to help establish the connection between the users, and the user can still Because of interest, group, active or passive to establish each other's connections, such as setting up friends with each other. In addition, users can also establish contact with each other through various community activities, especially the concept of peer-to-peer (P2P) sharing, which can save the bandwidth required by the server. In the future, it can be expanded to storage. Space and the sharing possibilities of computing power.

Moreover, under the framework of point-to-point sharing, the object delivery system proposed by the disclosure uses the social network as the target object indexing method, and the user registers as soon as the user needs to query the object through the keyword. Get a 64-bit (or other numbering) user number and map it to a unique user name based on the string. When the user specifies to share or needs to use a network resource to store an object, the object will be numbered as <user code>+<128bit object code>+<128byte object description string>, which becomes the only way to specify the object. .

The objects in the above may be files such as text, audio and video, and may also include message transmission between users.

The object delivery system specifically provides a user community composition manner, and the community is a general term, and a virtual collective formed by a user having a specific attribute or purpose after logging into a server, within a community It is also possible that different users have different goals and interests to form different groups. Users in the community can provide a community server through a community server to set up their circle of friends. The object delivery system can provide a server that can record each user's friends with their settings (with a relationship). If the user has installed the software provided by the community, the software itself can also record the user specified by the user. This establishes a basic group. See the basic group diagram in the community shown in the first figure.

In the first A picture, the user 10 can directly specify the friends A, B, and C, which are the most basic groups. The first B picture shows a strictly defined group, which is different from the way of designating a friend. In this case, the user applies for establishing a group, and the user acts as a group administrator, and then invites other users to join. A user who is authorized to join can become a member of the group. The figure shows a group 12 with other authorized users A', B', C'.

By establishing a group formed by each user and his friends, or first establishing a group, and forming a group with each authorized user, the object delivery system provided by the disclosure provides a target object and information for constructing the group relationship. The way of communication.

Moreover, a user may belong to different groups, and all the information of each user in the community should include private and public objects relative to the members of the group, and when obtaining specific objects transmitted by the group members, Can be set to private or re-public to other groups.

For example, if a user or group administrator in a community can specify to disclose or propagate a specific object, including files or information to be shared or recommended, the presence information of that particular object is automatically transmitted to all settings. The client program of a friend or related group member, including a web-based community program. Community users who receive this information can decide whether or not to download the object. In addition, the user can set the object to be an open domain object, and the related object information is transmitted to the logged-in user by the top-level index server when each user logs into the community, and the user decides whether to download the object. Or browse. According to one of the embodiments, in order to speed up the performance of the file transfer, the computer system used by each user or group administrator can become a cache of the whole community, the global object and the information.

After the user confirms the download, they will receive the objects (files, messages, and text messages) delivered by other users or group administrators. If the user decides to share or recommend them to their set friends or groups. The member can be designated as the cache node of the object, that is, the space as the temporary object, and then the information of the object existence is transmitted to the set friend or group member of the user.

When an object or any form of information is passed through the user, the user's friend, or a member of the group, a friend of the friend, or a member of the group, the more nodes are cached as a single object. The greater the available bandwidth for passing the object, the feature of point-to-point delivery.

According to the complexity of the social network of the community, through the propagation of multiple classes, it can achieve a surprisingly large number of purposes to achieve the purpose of a specific object broadcast broadcast (propagation broadcast).

In particular, in order to achieve high-speed, cross-domain transmission purposes, according to an embodiment, the object delivery system can provide a directory server, which is designed with a flow counter to provide various objects, information flow and statistics. The function. When a specific item is disclosed to be recommended by the community, the flow counter is counted to a certain amount, and sorted, it can be automatically added to a large number of recommended lists. If there is a specific user or group forwarding traffic that is large enough to a certain amount, this type of super node will record and load the object to be shared, and the above-mentioned public object will be automatically added to the list of directory servers. in.

After the initial user recommendation and transmission to the lower-level users, and then recommended and transmitted to the lower-level users by the lower-level users, or even set the cache node, after a period of time, a huge group can be established in the community. The network of object resource sharing. In particular, the user can define a resource sharing relationship according to the setting, and the user can share the computing resource/storage resource/bandwidth resource, etc., in the range of the sharable relationship. The object delivery system in the disclosure of the present disclosure, under the community structure, each of the shared objects or / and resources for individual processing of events, can be selected according to the respective target object different sharing list or a specific range of users, to achieve security And a balance of convenience. The above-mentioned lower-level users include their set friends, or members of the same group, and each group member may also belong to different other groups.

The second figure shows a schematic diagram of the sharing of objects in the community.

Users in the same community can belong to different groups. Through the community server, users can share various information by using the community server. The users who share and recommend objects can include friends set by themselves, or Other members of the same group become their lower-level users. The community server is also used to drive and act on various agents within the community.

As shown in the figure, the announcer 201 is the initiator of an object sharing, and can actively recommend the object to be shared to the lower-level user, such as the user 202, 203, 204 in the figure, after the object is obtained, the user 203 can share the same. (or recommended) to the lower level user 205, the user 204 can share or recommend to the lower level user 206.

When the user obtains the object, it can be set as the cache node at the same time, and becomes the cache point of the object. Therefore, when other users want to download the object, the user can follow the association of the upper and lower users among the users. Take the information to get the files from each cache point smoothly.

As shown in the figure, after the announcer 201 shares the object, it sets itself as a cache node, and the related information is also disclosed to each lower-level user. After the user 203 obtains the object, it can also be set as the cache node, and after the user 204 obtains the object, the same can be set as the cache node. The user 202, optionally, is not configured as a cache node for the object. The user 206 is a lower-level user of the user 204, and obtains the recommendation of the user 204 to obtain the object, and is also set as a cache node.

When the user 205 recommends the object by the user 203, when the object is to be downloaded, the cache node whose information has been updated may be from the announcer 201 and the user 203, 204, 206, and the user may refer to the dotted line in the figure. The object file can be obtained by each cache node following the dotted line.

The second figure shows the association between users in the object delivery system in the disclosure, and the association is achieved by the association. For a description of the related process, refer to the flow chart of the object transfer method shown in the third figure.

This process is applied to the virtual network community implemented by the computer network. At the beginning of the process, each user logs into a community server through various computer systems, such as a general personal computer or a handheld mobile host. In step S301, in the user interface provided by the community server 31, or through the interface of the external software to the community server 31, the shared object or/and information, such as a file, including the One or more other users, including sharing or referrals. In step S303, the information related to the object, such as the file name and the object description text of the object, if the object is an image or a movie, the information may be a thumbnail, and the various information is transmitted to the lower-level user, including the A friend set by the user, a friend who is matched by the system, or a member of the same group. According to an embodiment, a plurality of users in the same group are objects to be shared by the object, and are objects of information related to the object.

After the user downloads the object or/and the information by the lower-level user (step S305), the user receiving or transmitting can selectively set the client computer system 33 as a cache node (step S307), that is, due to each use. The file transfer mode in the community is a peer-to-peer protocol, so in addition to the download, a temporary file can be created in a specific storage space in the user computer system 33, which can usually be dynamic memory or hard. The file backup in the disc serves as a backup that other users can download, thereby speeding up the delivery of the object.

Furthermore, a directory server 35 can be selectively set up in the object delivery system. The directory server 35 is a server for collecting user activities in the community, including when the user initiates an object sharing, the object will be It will be registered in this directory server, and the relevant users of the group contact relationship will be notified of the path obtained by the object and the information of the cache node. Here, it can be used to record the objects of each node (the computer system of each user) or the server of the information flow (step S309), and after statistics, the object with the highest flow rate can be obtained, the hot list, or the specific The object performs statistics of each node, and the ranking of the hot node (associated to the user) is established, and the directory server 35 establishes a download list of various objects in accordance with this (step S311).

The above directory server is also used to collect file backups of various objects. Since each user's computer system may not always be in a networked state, or each user is not a normal login community, a specific cache node may be caused. Unstable, affecting the sharing of objects, so you can use the directory server to back up various object resources.

Please refer to the resource acquisition process provided by the object delivery system shown in the fourth figure.

At the beginning of the process, in step S401, the user will log in to the community server through the network. After the authentication, the server or other set friends or group members will obtain the public resource information (step S403), including various community messages. , or sharing and recommending information about specific items.

In step S405, after entering the community, the user can perform downloading for a specific object of interest, and the system will determine whether the file can be successfully obtained. This includes determining whether a directory server is required to be used as a cache node to obtain the object, or to download directly, or to perform downloading with other cache nodes. In the normal situation, the user can obtain the file from each end cache node through the peer-to-peer file access mode, but the file may not be successfully obtained (No), that is, in step S407, the file server can directly download and obtain, or It is performed with a valid cache node to perform peer-to-peer download; if the file can be successfully obtained (yes), or it is judged that the directory server is not required to be downloaded, it is processed in a normal condition, and each cache node performs a point-to-point download protocol. File (step S409).

After the object is successfully obtained, in step S411, the community server in the community will actively disclose the resource information of the object to the next-level user (including the set friend or group member), for example, the user sets the cache. Node, this information will be made public to group members or publicly available to the entire community. Next, each user will receive and update the published resource information by the directory server (step S413).

Next, for each item to share and recommend, the above steps can be repeated. If there is a node that is not online, the relevant information can be obtained from the directory server.

It is worth mentioning that when the user receives (downloads) the recommended object, it can be set as the cache node of the object, so the object has already obtained the cache of multiple load points in the community when the object is delivered. At this time, other users can find the available cache nodes of the object by the index function (may be provided by another server or by the community server), thereby speeding up other users and being able to The option selects no more than a specific number of cache nodes as download points, thereby dividing the file into multiple data blocks and downloading them to different cache nodes. If it is not available from each cache node, it can be obtained directly from the original announcer.

The traffic statistics of each node provided by the above directory server can automatically eliminate the cache nodes with slow connection speed, and the related records can be used for subsequent group communication reference.

After the user downloads, the menu can be used to set whether to recommend again. If yes, the recommendation is re-recommended, the node can be searched, and in a specific embodiment, the information of the object will be actively transmitted to the user. User.

Another feature is that the community server provides a mechanism to check for changes to the version of the object. When the object has been redesigned, the associated cache will be deleted and the download will be updated at the same time.

A schematic diagram of the system architecture for applying the above objects and information transmission process and resource acquisition process can refer to the fifth figure, including the manner in which resources are obtained through sharing and recommendation among users, in particular, obtaining files through cache nodes. The system architecture is mainly to connect the end user devices through the regional or wide area network 50.

The system is formed by a plurality of user terminals 505, 506, 507, 508 and the like, and a community server 501 is set up at the end of the network 50 by cluster, grid computing or workstation to establish a virtual network community server. The user management module 511 is configured to manage the user data, the account number, and the identification mode. The user management module 511 is preferably a management module implemented by using a software method, wherein the database can be used to store the login user. data. Each user should have a specific identification method. Users can connect and set other users as friends through system matching, self-contact or search. The settings of friends are mainly to realize the objects mentioned in this disclosure. The purpose of sharing and delivery.

Between friends, a virtual group with specific purpose or common features in a community can be formed. Users in the group can belong to other groups at the same time, and users in each group have a relationship (link). The group server 501 records the contact relationship through a group management module 512. The group management module 512 is also preferably a server module implemented by using a software means, when the user logs in to the community server 501. That is, the groups are connected with reference to the contact relationship provided by the group management module 512, and various messages transmitted by the group are received.

One end of the network 50 is provided with a directory server 503, which can also be a server implemented by clustering, grid computing or workstation. According to the descriptions of the first and third figures above, one of the uses of the directory server is to collect various uses. The file backup of the object passed between the two can be used as one of the cache nodes of the file. The user can directly download the file from the directory server, or perform one-point protocol download cache according to the connection of the client program. . The directory server has a special flow counter that provides various items, information flow and statistics.

The directory server has an object management module 531, preferably a function module implemented by using a software means, for collecting objects in the community, such as data files, messages, etc., when a user initiates an object sharing. The request, in addition to notifying its lower-level users, will be recorded in this directory server. Another node management module 532 can also be implemented by using a software method. The purpose is that when there is a specific shared file record, the cache node of the file can be simultaneously set as one of the cache nodes when the user downloads the file. . Since the cache node set for each user may cause other users to download incorrectly because the user is not online, or the computer system has a problem, the directory server can be used as a stable servo node.

Even when the cancellation is cancelled (for example, after a certain period of time, the cached content is deleted), if there is no other cache node in the file, the directory server is the only download point of the file.

In actual implementation, the above-mentioned community server and directory server may be two separate and independent server hosts, or two function modules (servers) in a server host (including clusters). Manage user accounts, group relationships, shared objects, and cache nodes separately.

In summary, the above discloses a scheme for transferring objects in a community, applying a peer-to-peer data transfer method to share and recommend specific objects among the set friends, and providing an object sharing mechanism in the network virtual community.

However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent structural changes that are made by using the specification and the contents of the present invention are equally included in the present invention. Within the scope, it is combined with Chen Ming.
