Abstract
The invention discloses a content processing method and system of a distributed service network (DSN). A content service application server distributes source content to a content server; the content server preprocess the source content according to a preprocessing strategy; and after the preprocessing is completed, the content server carries out content registration on a source positioning server. According to the scheme provided by the invention, the content server undertakes the preprocessing operation on the source content of the former content service application server, so that the processing property cost of the content service application server can be reduced, and a step of distributing a great amount of content to the content server preprocessed by the content service application server can be eliminated. Therefore, network transmission bandwidth desired by originally distributing the content can be greatly saved, and the efficiency of the system can be improved.
Description
Technical field
The present invention relates to network and the communications field, relate in particular to content processing method and the system of a kind of distributed business network (DSN, Distributed Service Network).
Background technology
DSN is that a new generation take P2P (peer to peer) as main distributed computing technology can run, manageable distributed kernel net system and function structure, can make up flexibly, extendible service environment, for the user provides content class service such as Streaming Media, voice class is professional such as multiple business such as mediaphones.
DSN content class service system can provide for dissimilar terminal uses content class service (such as program request, live and order etc.), therefore before providing content class service to the terminal use, the source contents that can provide content supplier carries out preliminary treatment, such as editor, transcoding and burst etc.
Fig. 1 is DSN content class service system for content initial distribution process, the content service application server is responsible for source contents is carried out preliminary treatment, then be distributed to content server, content server specifically comprised following step to resource locator server registration content information after distribution was finished:
Step 101: the content service application server obtains source contents from content supplier, then source contents is edited and is produced content metadata information, content is transcoded into the preliminary treatment such as different coding type and content fragment.
Step 102: by pushing or pulling mode, the content service application server is to content server distributing contents resource.
Step 103: after contents distribution was finished, content server was to resource locator server registration content information.
Can find out from above-mentioned flow process, because the source contents that provides of content supplier need to be distributed to content server after the preliminary treatment such as in advance adaptive, pre-burst through the content service application server again, the content service application server may need the expense of larger aspect of performance.Simultaneously, same content can form the content of multiple different type of coding behind transcoding, when the content initial distribution, may take a large amount of Internet Transmission bandwidth, reduces the operational efficiency of whole system.
Summary of the invention
In view of this, main purpose of the present invention is to provide content processing method and the system of a kind of DSN, can reduce the handling property expense of content service application server, and saves in a large number the required Internet Transmission bandwidth of content initial distribution, improves the efficient of system.
