It should be noted that this embodiment also provides an alternative implementation, which is described in detail below.

Fig. 2 is a schematic diagram of a video conference system according to an embodiment of the present invention, and as shown in fig. 2, an administrative tv conference system of a certain power company is divided into two layers, i.e., a backbone network and an intra-provincial network. The backbone network is built by the headquarters in a unified way and covers the headquarters, the branches and the headquarters of a certain company. The provincial and internal networks are built by a certain company, and the provincial and internal networks cover the local part of the provincial company, 8 prefectural power supply companies, 36 prefectural power supply companies, 4 prefectural power supply units, 9 direct-affiliated units or collective enterprises through development of many years.

The provincial administrative video conference system of the power company is provided with an MCU, and the maximum access number of the terminals is 100. And the transmission channel of the intra-provincial administrative video conference system adopts a data network special VPN mode. The MCU is respectively accessed to the provincial company intranet core switches 1 and 2 through the video access switches 1 and 2, and then is accessed to a data network through the metropolitan area network router and the provincial company access network core router, and the MCU shares provincial company intranet local area network resources with provincial company intranet office services and telephone services in side video services.

In addition, the provincial administrative video conference system of the power company is not provided with a recording and broadcasting server, does not have the functions of recording and replaying the conference and the like, and cannot meet the actual application requirements.

The project construction overall scheme comprises four parts, namely, the realization of a dual-computer hot standby mode of an intra-provincial administrative video conference system MCU, the optimization of an access mode of the main and standby MCUs of the intra-provincial administrative video conference system, the transformation of a 9660 type MCU upper-link switch and the configuration of an intra-provincial administrative video conference system recording and broadcasting system.

A video recorder (video recording and broadcasting singlechip) MCU (microprogrammed control unit) is in hot standby; when the MCU operates in a dual-computer hot standby mode and one MCU is abnormal, the system can automatically transfer the conference to the standby MCU according to a scheduling strategy, and the time for interrupting the conference is shortened as much as possible. The MCU dual-computer hot standby requires the hardware configuration of the main MCU and the standby MCU to be consistent, so the two MCUs, the two service management servers and the two hot standby switching servers need to be purchased again to be used as dual-computer hot standby. The service management server carries video service management system software, and can realize functions of video system configuration, resource management, conference control, authority management and the like. The hot standby switching server mainly realizes network switching in a main standby switching state.

And (3) the recent conference statistical data shows that the actual maximum bearing capacity of the MCU is 71 sides, and if the actual maximum bearing capacity is not more than 60% of the maximum capacity (the actual maximum bearing capacity/the maximum capacity is not more than 60%), and the maximum capacity is calculated to be 118 sides, the single MCU is configured according to 120 sides.

Fig. 3 is a schematic diagram of another video conference system according to an embodiment of the present invention, as shown in fig. 3, the MCU network is optimized; in order to reduce link nodes between the MCU and the core router of the provincial company access network and avoid the MCU from sharing bandwidth resources of the local area network with the side video service, the office network and the telephone service. Newly-added main and standby MCUs are respectively deployed in a first position communication machine room and a second position communication machine room, and the main MCU is doubly linked to two main and standby access switches deployed in an information network machine room at a first position; and the standby MCU is doubly linked to two main/standby access switches deployed in the communication machine room at the second position. The main and standby switches are interconnected and respectively connected to a core router I of the provincial company access network and a core router II of the provincial company access network.

The original MCU network access mode is unchanged, and the Cisco 6509 type core switch connected with the MCU network is replaced to improve the network reliability.

Configuring a recording and broadcasting system; in order to realize the recording function of the provincial administrative video conference and meet the use requirements of users, a high-definition video conference recording and broadcasting server needs to be additionally arranged. And the recording and broadcasting server interacts with the MCU through media streams, and simultaneously records the video, audio and demonstration of the conference process for viewing.

Project economy and financial compliance; the implementation of the project can further meet the use requirement, improve the stability and reliability of the provincial interior administration video conference system, contribute to the popularization and use of the administrative video conference system of the Qinghai electric power company, save a large amount of conference cost and travel cost, meet the policy of national diligence and thrifty conservation and the requirement of strengthening conference management inside the Qinghai electric power company, have the same project construction scale as the field reality, have no repeated project establishment problem, and meet the relevant provisions of the financial management of the national power grid company.

Construction transition measures are taken; the method is carried out one by one when the provincial company intranet core switch I and the provincial company intranet core switch II are dismantled. Firstly, all the services are migrated to a core switch II of the internal network of the provincial company, and after the normal operation of each service is confirmed, a newly-built switch I is replaced and configured. And migrating the service from the core switch II of the internal network of the provincial company to a newly-built switch I which normally operates, and after the service is confirmed to normally operate, replacing and configuring the newly-built switch II, wherein finally the two switches are in a double-machine hot standby state and operate well.

Difficulties and measures: after the newly-added MCU is installed and tested, the service needs to be transferred in a non-inductive way. In order to ensure that no influence is caused on the service after the new MCU bears the service, the MCU configuration needs to be carefully checked before the service is transferred, and each function needs to be fully tested and verified, so that the service is ensured to be stably transferred between new equipment and old equipment.
