All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Interpretation of terms:
NAS: a network attached Storage; a device literally connected to a network and having a data storage function is also called a "network storage". It is a dedicated data storage server. The data center is used for completely separating the storage equipment from the server and managing the data in a centralized manner, so that the bandwidth is released, the performance is improved, the total cost of ownership is reduced, and the investment is protected. The cost is far lower than using server storage, while the efficiency is far higher than the latter.
P2P: a Peer-to-Peer network, i.e., a Peer-to-Peer computer network, is a distributed application architecture that distributes tasks and workloads among peers (peers), and is a networking or networking form of a Peer-to-Peer computing model formed in an application layer. Literally, P2P may be understood as a peer-to-peer computing or peer-to-peer network. Some of the media in China translate P2P into "Peer-to-Peer" or "Peer-to-Peer," which is commonly referred to by the academic community as Peer-to-Peer networking (Peer-to-Peer computing), and can be defined as: participants of the network share a portion of the hardware resources (processing power, storage power, network connectivity, printers, etc.) they own, which provide services and content over the network and which can be accessed directly by other Peer nodes (peers) without going through intermediate entities. The participants in this network are both providers (servers) and acquirers (clients) of resources, services and content.
Token bucket algorithm: when data is transmitted in a network, in order to prevent network congestion, it is necessary to limit the traffic flowing out of the network so that the traffic is sent out at a relatively uniform speed. The token bucket algorithm performs this function, controlling the amount of data sent onto the network and allowing the transmission of bursts of data.
The purpose of this application lies in: the media files of the head office server are distributed to the terminals of all network points, and the media file distribution efficiency can be improved, and occupied network bandwidth occupation and resource waste can be reduced.
The present application provides a file distribution platform, and referring to fig. 1, the file distribution platform includes:
the head office management device 100 is used for uploading media files and branch media file lists to a head office server.
A head office server 200 connected to the head office management apparatus 100 for storing media files and branch media file lists.
The plurality of branch servers 300 connected to the head office server 200 are configured to obtain a branch media file set from the head office server in units of branch servers, so as to ensure that each media file is transmitted only once on the backbone network between the branch servers and the head office server.
Each branch server 300 jurisdiction includes a plurality of network points, each network point generally includes at least one terminal 400 for displaying media files, and the network points are not intercommunicated with each other. All terminals of the file distribution platform are divided into a plurality of terminal sets which are in one-to-one correspondence with a plurality of network points by taking the network points as units.
The plurality of terminal sets 400 connected to the plurality of branch servers 300 in a one-to-one correspondence are configured to obtain a website media file set from a branch server using a terminal set of a website as a unit, and distribute the website media file set in the terminal set of the website, so as to ensure that each media file is transmitted only once between the branch server and the terminal set.
As can be seen from the above description, the present embodiment has the following beneficial effects:
according to the method and the system, the branch media file set is obtained from the head office server through the branch server, so that each media file is transmitted once between the head office server and the branch server, the transmission times of the media files between the branch server and the head office server are greatly reduced, and the occupation of network bandwidth and the waste of resources are reduced.
All terminals of the file distribution platform are divided into a plurality of terminal sets by taking a branch as a unit, and the terminal sets are used as media file sets of the branch servers, so that each media file is transmitted once between the branch server and the branch, the transmission times of the media files between the branch server and the branch are greatly reduced, and the occupation of network bandwidth and the waste of resources are reduced.
Subsequently, the media file set of the network point is distributed to each terminal in the terminal set, so that the media file distribution process is realized in the network point, the media file distribution efficiency can be improved, and occupied network bandwidth occupation and resource waste can be reduced.
The application provides a media file distribution method which is applied to a file distribution platform shown in figure 1. Referring to fig. 2, the media file distribution method includes the steps of:
step S201: the head office management apparatus 100 determines a plurality of media files and a branch media file list corresponding to each branch server 300, and uploads the plurality of media files and the branch media file list corresponding to each branch server 300 to the head office server 200.
Step S202: the head office server 200 receives and stores a plurality of media files and a branch media file list corresponding to each branch server 300.
The head office server has a plurality of file transfer entries, which can be stored in commonly accessible NAS.
Since the backbone network from the head office server 200 to the branch office server 300 is used by both the production process and the office process, and the backbone network involves a large amount of key information transmission and has a large flow rate, the head office server 200 can distribute media files to the branch office servers 300 at night under the optimal condition, and a speed limit mode can be started in the process of distributing the media files so as to be suitable for network bandwidth between the head office server and each branch office server.
The head office server can directly determine the branch media file set according to the branch media file list and send the branch media file set to the branch server, and can also send the branch media file list to the branch server so that the branch server can actively acquire the branch media file set. Both implementations can be realized according to actual conditions. For convenience of description, the following embodiments are described by taking the case that the branch server actively acquires the branch media file set as an example.
Step S203: the branch server stores the media file lists of all the network nodes and the terminal media file lists of all the network nodes.
The branch management personnel are used for uploading terminal media file lists of all the branches and network point media file lists of all the network points to the branch server.
Taking a network as an example, the terminal media file list includes terminal identifiers of a plurality of terminals and identifiers of media files that each terminal should distribute to obtain. And the union set of all the media file identifications in the terminal media file list is the media file list of the network points.
Step S204: the branch server stores terminal information of each network point in the administrative area, and the terminal information of one network point comprises terminal identifications and terminal states of each terminal under the network point.
The jurisdiction range of the branch server comprises a plurality of network points, each network point comprises a plurality of terminals, and the terminal information of the terminals forms the terminal information of one network point. Each terminal information includes a terminal identification and a terminal status, and the terminal status includes an available status for indicating that the terminal is in a good status and an unavailable status for indicating that the terminal is in a fault status.
Step S205: and the branch server dynamically determines the main terminal in an available state in a terminal set corresponding to the network point according to the terminal information of the network point.
For each network point, the branch server can dynamically select a main terminal in the network point according to the terminal information of the network point, wherein the main terminal is a terminal which is in an available state and generally has less resource usage among a plurality of terminals of the network point. The other terminals except the main terminal in the network point terminal set are slave terminals.
Step S206: the branch server sends a main terminal updating instruction to a terminal set of a network point; wherein, the updating instruction of the master terminal comprises a terminal identification used as the master terminal.
After determining the master terminal, the branch server distributes an update instruction containing the terminal identifier of the master terminal to a terminal set of a network point, so that the terminal set terminal can know that the terminal set terminal is the master terminal or the slave terminal.
Step S207: terminals in a terminal set of the network point receive a master terminal updating instruction, a master terminal end and a slave terminal are determined, and the slave terminal and the master terminal establish communication connection.
Each terminal in the terminal set receives a main terminal updating instruction; and determining that the terminal is a master terminal under the condition that the terminal identification of each terminal is consistent with the terminal identification in the master terminal updating instruction, otherwise determining that the terminal is a slave terminal.
Each slave terminal in the terminal set is connected online end-to-end with the master terminal (P2P) for subsequent communication in the terminal set in P2P.
In addition, the branch server is used as a main bearing node for the terminal to acquire the media file, and a double-WEB server and a double-AP mode can be adopted to ensure the correctness and better load balancing capability of the branch server. And the maximum network pressure and service pressure provided by a single AP can depend on the token bucket algorithm to carry out current limiting and speed limiting guarantee.
The above is a pre-processing process, i.e., an off-line processing process, and the following is a real-time, i.e., on-line processing process of the present application.
Step S208: the branch server 300 obtains a branch media file set from the head office server in units of branch servers to ensure that each media file is transmitted only once over the backbone network between the branch servers and the head office server.
This step can be implemented by the following steps:
s1: and the branch server acquires a branch media file list corresponding to the branch server from the head office server.
The branch server may send an http request, where the http request includes an identifier of the branch server, so that the head office server searches for a branch media file list corresponding to the branch server, and issues the branch media file list to the branch server.
S2: and the branch server downloads the media files in the branch media file list from the head office server, and the downloaded media files form a branch media file set.
The branch media file list comprises media file identifiers, the branch servers acquire the media file identifiers one by one from the branch media file list, and download the media files corresponding to the media file identifiers from the head office server until the media file identifiers on the branch media file list are completely downloaded.
If the downloading fails in the downloading process, recording the media file identification of the downloading failure so as to feed back the media file identification to the head office server for the head office server to check the media file, and if the media file identification is damaged, re-uploading the media file so as to add the media file identification to the branch media file list of the next period so as to re-distribute the media file to the terminal in the media file distribution process of the next period.
In order to avoid network congestion or downtime in the media file distribution process, the distribution server sets a current limiting and current limiting service, and the maximum resource consumption of the branch server is the maximum current limiting and the maximum speed limiting. The maximum resource consumption is the maximum resource consumption which can be generated by the branch server in the media file distribution process.
The branch server can directly determine the website media file set according to the website media file list, and sends the website media file set to the terminal set of the website, and can also send the website media file list to the terminal set of the website so that the terminal set can actively acquire the website media file set. Both implementations can be realized according to actual conditions. For convenience of description, the following embodiments all describe the case where a terminal set actively acquires a media file set of a website.
Step S209: the method comprises the steps of taking a terminal set of a website as a unit to obtain a website media file set from a branch server, and distributing the website media file set in the terminal set of the website to ensure that each media file is transmitted only once between the branch server and the terminal set.
This step is performed for each mesh point, and can be implemented by the following steps:
s1: and the main terminal in the terminal set receives the website media file list and the terminal media file list which are sent by the branch server and correspond to the website.
The branch server issues a branch point media file list and a terminal media file list corresponding to the branch point to a main terminal in a terminal set, and the main terminal in the terminal set receives the branch point media file list and the terminal media file list corresponding to the branch point issued by the branch server.
S2: and the main terminal in the terminal set downloads the media files corresponding to the website media file list from the branch server, and the downloaded media files form the website media file set.
The website media file list comprises media file identifications, the main terminal acquires the media file identifications one by one from the website media file list and downloads the media files corresponding to the media file identifications from the branch server until the media file identifications on the branch media file list are completely downloaded.
S3: in the local area network where the website is located, the main terminal in the terminal set distributes the media files in the website media file set to each terminal in the terminal set in a P2P mode according to the terminal media file list.
Each terminal in the jurisdiction range of the network is in the local area network, so the terminal set master terminal can distribute the network media file set to each terminal in the local area network, and particularly, the corresponding media file is required to be distributed to the corresponding terminal according to the terminal media file list in the file set distribution process.
In order to improve the distribution efficiency, the master terminal and the slave terminal communicate by adopting a P2P mode.
If the media file can not be successfully distributed in the distribution process, the media file identification of the media file is sent to the branch server so that the branch server can check the media file, if the media file is damaged, the head office server is informed so that the media file identification can be added to a branch media file list of the next period so that the media file can be distributed to the terminal in the media file distribution process of the next period, and the fault tolerance of the distribution process is guaranteed.
The terminal concentration terminal of the network node is arranged in a star structure, the Master terminal is also called a Master node (Master), and the slave terminal is also called a slave node (Salver). After the main terminal downloads the media files from the branch servers and acquires the media file sets of the network points after downloading the media files, the media file sets of the network points are distributed from the main terminal to all the slave terminals through the message sharing mode in the high-speed local area network mode of the network points, and only the media files required by each slave terminal are pushed.
It can be understood that the main terminal in the terminal set may be down, and the branch server dynamically determines the main terminal again after the main terminal is down; and the master terminal update instruction sent by the branch server is sent to the terminal set.
A terminal set of the network node receives a main terminal updating instruction issued by the branch server; the updating instruction of the main terminal comprises a terminal identifier used as the main terminal; each terminal in the terminal set receives a main terminal updating instruction; and determining the terminal as a master terminal under the condition that the terminal judges that the terminal identifier is consistent with the terminal identifier in the master terminal updating instruction, otherwise determining the terminal as a slave terminal, and establishing communication connection between the slave terminal and the master terminal.
If the downtime of the main terminal is in S1 and S2 of step S209, it indicates that the main terminal is downloading the website media file list or downloading the website media file set, and the distribution of the website media file set has not yet started, so that at this time, the updated main terminal directly re-executes step S209 to download the website media file list and obtain the website media file set.
If the downtime of the main terminal is in S3 of step S209 and the distribution of the website media file set has already started, then directly executing step S209 may cause a problem that some terminals have duplicate media files, so that at this time, the rollback will be executed on the terminal set and the state before the media files are distributed. Then, step S209 is executed again by the current master terminal.
The above is a process for automatically distributing media files, and the present application also provides a process for manually distributing media files for use in situations where automatic distribution is not yet performed or is otherwise in a particular situation. That is, the branch servers provide a manual distribution interface.
Step S301: receiving a manual distribution instruction input by a user in the process of displaying the branch media file list on a display screen; wherein the manual dispatch instructions include: one or more media file identifications in the media file list, a terminal set corresponding to each media file identification and a terminal identification corresponding to each media file identification.
After receiving a manual distribution instruction containing one or more media file identifications, the branch server determines a terminal set of the one or more media files and terminal identifications needed to be distributed to terminals in the terminal set.
Step S302: and the branch server determines one or more media files corresponding to the one or more media file identifications.
And the branch server extracts one or more media files corresponding to the one or more media file identifications according to the one or more media file identifications.
Step S303: and distributing the one or more media files to a main terminal in a corresponding terminal set so that the main terminal in the terminal set distributes the media files to the terminal corresponding to the terminal identification.
This step is similar to step S209 and will not be described herein.
Step S304: deleting one or more media file identifications in the branch media file list.
After the manual distribution is finished, the branch server deletes one or more media file identifications manually distributed in the branch media file list so as to avoid repeated redistribution to the terminal in the automatic distribution process.
The main technical conception of the invention is as follows: all terminals of the file distribution platform are divided into a plurality of terminal sets by taking a website as a unit, a non-repeated website media file set is acquired from a branch server by taking the terminal set as the unit, and then the acquired website media file set is distributed in a local area network in a P2P mode. Therefore, the transmission quantity of the media files can be transferred to the network nodes, and the transmission quantity of the media files can be solved in the local area network of the high-speed network nodes.
The method and the system also take the branch servers as units to obtain the branch media file sets from the head office server, so that the resource occupation of a backbone network between the branch servers and the head office server is reduced. The purpose that the media file can be distributed from the head office server to all terminals, a plurality of terminals or a single terminal can be achieved by the two main parts.
Through the technical characteristics, the following beneficial effects can be obtained:
the method and the system support the function that the head office server distributes the media files to the branch servers, the branch servers distribute the media files to the terminal sets, and the branch servers can also provide manual distribution interfaces, so that the function of appointing to distribute the media files or appointing distributed terminal identifications can be realized.
The method and the device are suitable for distributing the large media files, and occupied network bandwidth and network resources can be effectively reduced.
The method and the system can effectively reduce the transmission times of the media files of the backbone network between the head office server and the branch office server, and also can effectively reduce the transmission times of the media files of the network between the branch office server and the network points, thereby greatly reducing the occupation of the network bandwidth, and being particularly suitable for the transmission of large media files.
After the terminals are added in the terminal set, the transmission quantity of the media files of the backbone network is not increased, but the transmission quantity of the media files is transferred to a high-speed local area network in the terminal set, that is, most of the transmission flow is limited in the high-speed local area network of a network point, so that the resource occupation of a head office server and a branch server is small, and the exponential increase of the resources along with the increase of the terminals is avoided.
