Here said Service coverage is meant service deployment planning, as, professional related zone and related network node, wherein, can Service coverage be divided into many levels according to service needed, each layering corresponding service coverage, last layer is contained the Service coverage of next level.Service coverage can be the geographic range in an area, also can be trans-regional scope, and the network node under the same Service coverage is born identical business function or service usually, thereby has identical business configuration demand.Here said business rule is meant business function or the service of bearing according to network node, to the network node distributing network file of corresponding business coverage, and can be during each distributing network file based on identical or different business rule.
Below in conjunction with Fig. 2, the network file distribution flow that the embodiment of the invention is provided is described.
Referring to Fig. 2, be the network file distribution flow schematic diagram that the embodiment of the invention provides, this flow process mainly comprises:
In this step, system configuration module 101 comprises root node, leaf node and the intermediate node between root node and leaf node according to the network file distribution tree of Service coverage configuration, and it is multistage that intermediate node can comprise that one-level also can comprise.Wherein, root node is used for describing the professional total size that covers; Leaf node is used for describing network node information, and the network node that leaf node is described is the receiving terminal network node of the network file of distribution; Intermediate node is used for describing the professional subrange that covers in the total size.Several one-level subrange nodes of one deck definable are as intermediate node under the root node, several secondary subrange nodes of definable again under the one-level subrange node, and recursion in this way is till setting certain node and being leaf node.Intermediate node is used for defining the attribute of the subrange of certain classification, describes as Service coverage; Leaf node is used for defining the attribute of the network node that receives network file, as information such as network node address, identification code, title or geographic areas, place.In the path from the root node to the leaf node the stack of the Service coverage attribute described of the node of process be exactly Service coverage attribute under this leaf node.In theory, the level of network file distribution tree can infinite expanding, for business rule definition and adjustment provide the foundation.
Fig. 3 has provided a kind of structural representation of network file distribution tree.As shown in Figure 3, this network file distribution tree comprises root node 301, intermediate node 302,303,306,308,309, and leaf node 304,305,307,310.Root node 301 is described the professional total size that covers, be divided into a plurality of one-level subranges in this total size, among Fig. 3 by intermediate node 302,308 describe the one-level subrange, can be divided into a plurality of secondary subranges under the one-level subrange again, among Fig. 3 by intermediate node 303,306,309 describe the secondary subrange, comprise one or more network nodes under the secondary subrange, in Fig. 3 respectively with node 304,305,307,310 expressions, node 304,305,307,310 have described the information of corresponding network node, and network node information can comprise that the network address of node is or/and node identification.
In this step, in order to generate the network file distributed tasks, can pass through task layout module 102, the business rule that adopts according to this time, it is the Service coverage that network file to be distributed will arrive, from the network file distribution tree, select the node of this scope of expression, carry out the network file distributed tasks then and generate instruction, single to generate the network file distributed tasks.The node of selecting from the network file distribution tree can be a root node, also can be one or more intermediate nodes, also can be leaf node, can also comprise intermediate node and leaf node.If what select is root node, network file then to be distributed will be distributed to all leaf nodes in the represented Service coverage of root node; If selected intermediate node, network file then to be distributed will be distributed to all leaf nodes under this intermediate node; If selected leaf node, network file then to be distributed will directly be distributed to this leaf node.Like this, the system manager just can conveniently select the receiving terminal in the Service coverage, the granularity of its management and selection can be slightly to root node (being the all-network node), and can carefully arrive leaf node (i.e. network node), thereby the means of adjusting are easily provided for needs according to the Content Distribution Network file.
Because the distributing network file is that unit rather than a concrete file are the unit with certain business packet normally, therefore, task layout module 102 provides job order layout function, and generating with the business packet is the network file distributed tasks list of unit.Comprise with the business packet being the network file tabulation to be distributed of unit and all receiving terminal network node information (as the sign or the network address of network node) of the file in the tabulation of this network file during the network file distributed tasks that generates is single.The information (as file name, file size, file storage location etc.) of network file to be distributed has been described in the network file tabulation, can also comprise professional use information (for example reproduction time of network file etc.) in this tabulation, comprise that specifically which information need be defined by operation system.Also comprise Service coverage information during the network file distributed tasks is single, this Service coverage is the described Service coverage of selected node from the network file distribution tree.Task layout module 102 singly is saved in designated storage location with the network file distributed tasks that generates, preferably, the network file distributed tasks stores the network node that all leaf nodes in the network file distribution tree can both have access to into, as the visible server of the overall situation.
Network node in step 203, the network file distributed tasks is initiated the file access request according to this network file distributed tasks.
In this step, trigger network node initiation file access request mode has multiple, and the embodiment of the invention provides following triggering mode:
Mode one: trigger by the network node network file distributed tasks that inquiry is relevant with oneself automatically, in this mode, all leaf nodes in the network file distribution tree are regularly from storing the network node requester network file distributing task of network file distributed tasks, comprise this node self if inquire the network node that comprises in certain or some network file distributed tasks (being the receiving terminal node of network file to be distributed), the request of then initiating is to visit the network file in this task;
Mode two: the notification message that sends by the network file dissemination system triggers, in this mode, send the notification to the network node in this task after the task layout module 102 generation network file distributed tasks, the network node that receives this notice is initiated request to visit the network file in this task.
Before network node is initiated the file access request, can generate the network file downloading task according to the network file distributed tasks, comprise listed files in the downloading task, the included file of the included file of this document tabulation and the listed files in the distributed tasks is identical, then according to download policy initiation file access request when carrying out this downloading task.
In this step, after file distributing module 103 is received the file access request of network node initiation, according to file name to be distributed listed in the job order and source stored position information with initiate the network node information of request, obtain network file to be distributed and send it to this network node from the memory location, source of appointment.If job order also uses in the operation system of receiving terminal network node, then this job order itself also can be used as a file task and puts into the distributed tasks list, so that be distributed to the receiving terminal network node together, to the processing mode of this job order with the same to the processing mode of the file to be distributed in this job order.
