Broadcast Network Optimization Technical Reformation Program Of Nanjing Broadcasting Group

Along with the national radio and television media integration, digitization, network construction put forward," the media" concept has become the inevitable trend of the development of radio and television. Nanjing broadcasting network system constructed from the2003until now, has never been a large-scale technical transformation and optimization. However, the radio frequency increases, radio broadcast security requirements to improve the business expansion, the development of new media and so on, are associated with increasing lag network and equipment are contradictory, accordingly, be badly in need of a comprehensive upgrade, in order to better adapt to the development of new media and its application.The transformation includes radio office presentation network system upgrade, radio audio broadcast network system, radio and audio production network platform construction and upgrading of audio workstation system. Broadcast from the security and programming point of view, radio office network and audio network for network safety and reliability have higher requirements, therefore, in the network configuration, choice of star type topological structure, and configure the VRRP, while retaining the original available equipment, new equipment, used equipment for the preparation of form, realize the core part of the redundant heat standby scheme; by dynamic VLAN division, realize the LAN users flexible grouping; select H3C related core, access switch, through the configuration of security strategy, realizes the user management, user behavior monitoring. In addition, the audio production services platform between the office network and audio networks, audio resource file and directory structure of the two networks, storage platforms are mirror images and backup storage mirroring system, internal and external network interoperability. In the transformation process, around the new network structure, equipment and other changes, for audio workstation software provider of higher demand. As a software using method, organization software user function test. After the test, the test results are analyzed and summarized, and the software provider to provide improvement suggestion to software testing, software as a basis for acceptance.After the transformation of the office network, audio network, as well as the new audio production services platform has entered into the trial stage of commissioning, from safety and stability, can be very good to meet the needs of users; upgraded audio workstation system has been basically through the software test, entered into the trial stage.
