In one embodiment of the invention; Physical network and virtual network through own combine, and dispose at the virtual private node of having network by oneself, reach physical network, virtual network, data analysis, direct traffic and combine; Thereby make and quicken more smoothness, more stable.
Through disposing access node in operator; Own network takes EOC (transmission of ether data coaxial cable), PON (EPON), PTN combinations such as (group transmission networks) to realize users' at different levels access; The mode of taking OTN (optical transfer network), PTN (group transmission network), ASON (ASON) to combine is built the platform that carries the network optimization system in the present embodiment, and carrying platform combines distributed deployment IDC and CACHE with intelligent data switching plane characteristics (data flow to client is analyzed); The network data exchange combines with the terminal routing function; And the operation through terminal software, from cost, efficient, three aspect comprehensive considerations such as quality; Carry out new set and insert, carry, exchange, store, reach network acceleration.
The SinoNet network that network optimization system in the present embodiment is realized is made up of client terminal machine (client software can be installed), DPI server 302, applied analysis server 304 and DB (database) server 306, and is as shown in Figure 3 with applied analysis server 304 at the some DPI servers 302 of network backbone node deployment.Client software is delivered to DPI server 302 to user's data through the Internet, and 302 pairs of user's data streams of DPI server are resolved, and distinguish the agreement of different application; Send to applied analysis server 304 to the data of these application of distinguishing; Applied analysis server 304 is analyzed the data content based on aforesaid agreement, makes a concrete analysis of out the application of transmission data flow, to different application; Be routed to data on the fastest destination server, specific as follows:
1, client software: deliver to user's data on the DPI server 302 of appointment.
2, the DPI server 302: resolve to data flow, distinguish the application which agreement is different data flow all belong to.
DPI server 302 is handled data stream based on the data identification of tagged word.Different application depends on different protocol usually, and different protocol all has its special fingerprint, and these fingerprints possibly be specific port, specific character string or specific Bit sequence.DPI server 302 based on the recognition technology of " tagged word " through being the application of which agreement with what confirm that Business Stream carries to " fingerprint " detection of information in the specific data message in the Business Stream.According to the difference of concrete detection mode, can be divided into characteristic matching and three kinds of technology of status flag coupling of fixed position tagged word coupling, changing position again based on the recognition technology of " tagged word ".Through upgrading to " fingerprint " information, can carry out the function expansion very easily based on the Feature Recognition technology, realize detection to New Deal.
3, the applied analysis server 304: the data flow that 302 analyses are come out to the DPI server is carried out further content analysis according to the form of agreement, analyzes to belong to concrete the sort of application, and sends analyzing the fastest server of application choice that comes out.Simultaneously, can select a route or many routes to come transmitting data stream, to alleviate the pressure of network data transmission based on the data volume size of data flow.
4, the DB server 306: can store routing table, wherein write down the server node corresponding to different application.Applied analysis server 304 finds out the server into the distribution of flows of different application, with transmitting data stream according to routing table.
Through top three steps, can optimize and a route the fastest, thereby carry out network acceleration.Terminating machine pc carries out data through terminating machine software and is routed to the SinoNet network, and the SinoNet network is delivered to named place of destination to the data of pc machine through the method for above-mentioned data analysis.
Can find out by above; The present invention at first analyzes (mainly being protocal analysis, applied analysis, the adress analysis to data) to data; Through can understand the trend of data flow to the analysis of using, the decomposition network flow pressure can effectively be shunted data; Avoid a certain networking data volume is resulted in blockage greatly; Selecting optimum route to send to destination address to the data that analyze is exactly to select unobstructed networking, thereby reaches the purpose of acceleration, can not cause time-delay because of the obstruction of data.What problem solved is that the data traffic of network has been carried out effective shunting and control at all; The method and the process of shunting and control are exactly the process of data analysis and data route; These two processes are deployed in the respective nodes of network through aforesaid each module; Come the obstruction of Control Network with the principle of data analysis, optimized network environment.
Through above technical scheme, can realize a kind of network optimization system and a kind of network optimized approach, can dispose and development has flexible, an extendible network, keep the unimpeded of information flow and satisfy instructions for use most important.The load of carrier network has become the big problem that threatens internet development; The present invention has reduced 50% with its bandwidth in the business expansion; Speed has improved 80%, need the upgrade application program of bandwidth intensive of operator, and upgrading has been accomplished in this system help; Not only quicken bandwidth, also optimized data flow.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
