Disclosure of Invention
Aiming at the defects of the prior art, the invention discloses a registration signaling intelligent response method based on Redis video equipment information management. The main purposes of the invention are as follows: through the management of Redis on the video equipment information, the intelligent response of the video equipment registration signaling accessed by the standard technology of GBT 28181 and 2016 public safety video monitoring networking system information transmission, exchange and control technical requirements is realized, and the accuracy of operation and maintenance personnel on the video equipment access management is improved.
Technical terms:
redis: is a key-value storage system. Similar to Memcached, it supports relatively more stored value types, including string, list, set, zset, and hash. These data types all support push/pop, add/remove, and intersect union and difference, and richer operations, and these operations are all atomic. On this basis, redis supports various different ways of ordering. Like memcached, data is cached in memory to ensure efficiency. The difference is that the redis can periodically write updated data into a disk or write modification operation into an additional recording file, and master-slave synchronization is realized on the basis of the update. Data may be synchronized from a master server to any number of slave servers, which may be master servers associated with other slave servers. This enables Redis to perform single-level tree replication. The storage disk can write data intentionally or unintentionally. Due to the fact that the publish/subscribe mechanism is completely achieved, when the trees are synchronized anywhere from the database, one channel can be subscribed and the complete message publishing record of the main server can be received. Synchronization is helpful for scalability of read operations and data redundancy.
Redis is a high-performance key-value database. The occurrence of redis greatly compensates the shortage of key/value storage such as memcached, and can play a good role in supplementing the relational database in some occasions. The method provides clients such as Java, C/C + +, C #, PHP, JavaScript, Perl, Object-C, Python, Ruby, Erlang and the like, and is convenient to use.
SIP service: receiving SIP signaling, and a service program responding to the received SIP signaling.
