With the rapid development of information technology,such as network technology,digital technology and storage technology,the broadcasting and television industry has gradually realized networking on adoption,edition and playing.According to the business function,a number of proprietary business systems like "information island" are established.As the production network of production and broadcast,security is the first priority,and it should be linked with the office network by physical isolation.However,with the development of business requirements,the physical isolation network can guarantee security,but the import and export of Internet materials must be manually transferred through mobile storage medium,the steps are cumbersome and the production efficiency is low.This article will refer to the relevant experience,considering how to design a safe,standardized,efficient link file transmission system,and break the bottleneck of the original system "information island" which can not realize the mutual communication.The data interaction between office network and production network based on business process is realized.In order to solve the problem of "information island",this paper designs a data exchange mode under the SOA framework and unifies the service interface of each "isolated island" business through the investigation and understanding of establishing data exchange platform in different industries.The purpose of data interconnection is achieved by format conversion of the acquired service interface data.At the same time,the two solutions of the current mainstream isolated network transmission technology,including setting up a proprietary network gate system and using a variety of heterogeneous protocols,respectively study their advantages and disadvantages and compare them to realize the data exchange between the isolated networks.In this paper,different transmission channels are designed based on relative information about the data type and transmission direction of broadcast TV service.It will adopt modular structure,the user access architecture of B/S.And the uploading and downloading service is implemented with FTP and HTTP protocol.In the office network and the production network,the multi-stage transmission nodes of USB channel are deployed to form the matrix server group,to improve the bandwidth of the server and to complete the data exchange between the internal and external networks.The software and hardware security protection system,which combines multiple heterogeneous protocols and multilevel heterogeneous virus library,is used to prevent and guard against the invasion of viruses and network attacks.At the same time,the security protection strategy is set up accordingly in the configuration of the system.By limiting file type and file header information,to prevent malicious tampering on the system penetration damage.Finally,the high-security,automated and processed mutually fast data exchange between the Internet,office network and production network is realized,and the work efficiency is improved accordingly. |
