Dingxin Tongda uc8000 series IPPBX dual computer hot standby solution

with the process of all IP communication, IP based voice, video, conference and integrated communication have been widely used in modern enterprises. As the core part of the communication system, the IPPBX deployed by enterprises is particularly important to ensure high reliability and security, which has also become a standard to test the system capability

uc80 launched by Dingxin Tongda adopts a kind of 00 series IPPBX with smaller size as far as possible. It is an enhanced soft switch system developed based on the latest technology. It adopts a soft switch + hardware server architecture, which can provide a highly reliable solution for dual computer hot standby. Through the technical solution of hardware redundancy and high availability dual computer hot standby software, it can automatically detect the running status of the server. When the host fails, it can immediately switch to the standby computer to take over the business, The customer has no perception and switches at the second level to ensure the uninterrupted operation of the business system and provide a stable and reliable communication guarantee for the enterprise

description of dual computer hot standby architecture

in order to solve the problem that the communication system can still work normally under the influence of uncontrollable factors and highly ensure the uninterrupted communication of users, it is necessary to adopt the dual computer hot standby mode to ensure the high reliability of the system. Dual machine hot standby is a combination of hearbeat, PostgreSQL master-slave configuration and daemon

heartbeat is responsible for heartbeat detection between master and slave servers. When it is detected that the master server does not send heartbeat packets within the specified time, it is judged that the master server has failed. Heartbeat will immediately set the slave server as the master server to take over the business, so as to ensure that the user communication system will not be affected by the failure. At the same time, the dual computer hot standby configuration of the database, when the user writes data to the database, will be written into the databases of the master and slave servers at the same time. When the master database fails or breaks down, the slave database server can be switched immediately to ensure the loss of user data

the intelligent daemon of the uc8000 system will monitor whether the business system status is running normally in real time. If it detects that the daemon stops working, the daemon will try to restart it, so as to ensure that both the master and slave server systems are running normally. In addition to heartbeat heartbeat detection, the IPPBX server equivalent to a single machine also performs master-slave synchronization and failover of PostgreSQL databases. Ensure that the data configuration of the master-slave soft switch node is consistent. When the server fails and goes down, the standby server will be automatically switched. The PostgreSQL database role will also be automatically switched to the master

deployment method 1: the IPPBX system and database are deployed on the same server

there are not many enterprise users, there are few call business data, and the requirements for the safe storage of user dialog lists, recordings and other data information are not particularly high. The IPPBX and database can be deployed on the same server to realize the dual computer hot standby deployment scheme. Heartbeat detection can be deployed on the two uc8000 servers respectively, The general experimental method of eth1 building adhesive gb/t 12954 ⑼ 1 interface is used for heartbeat detection. The eth0 interface is externally used for running call service. The eth0 interface of the slave server is down by default. When the main server is detected to be down, the standby server automatically enables the eth0 interface of the machine, so as to transfer all the services of the main server to the standby server. All data of the active and standby servers will be synchronized in real time. To ensure the consistency of data when the active and standby servers are switched, the new material is one of the seven strategic emerging industries in China, which protects the stable operation of the user's communication system

deployment mode 2: IPPBX and database are deployed separately, and dual database backup

if users have high requirements for data security storage, and data is particularly important to customers, a highly reliable solution of IPPBX soft switch and independent deployment of databases can be adopted. IPPBX realizes dual computer hot standby, and dual databases are deployed to realize data disaster recovery backup, which can ensure the security of customer data, Heartbeat detection is deployed on the two uc8000 servers that are far from the market demand. The eth1 interface is used for heartbeat detection. The eth0 interface is connected externally for running call services. The eth0 interface of the slave server is down by default. When the main server is detected to be down, the standby server automatically enables the eth0 interface of the local server, so as to transfer all the services of the main server to the standby server. In addition to the soft switch service, there is also the master-slave synchronization and master-slave switching script of PostgreSQL. Uc8000 will send CDR bills, recordings and other data to the master and standby database servers at the same time, so as to realize the synchronization of business data and disaster recovery backup, and protect the stable operation of the user's communication system
