As shown in figure 4, realizing that container service is divided into two parts of control node and calculate node, control node includes to money Balance, storage management, network management and the task schedule function in source, calculate node include the operation and management, KPI index of container The functions such as monitor and report.

Specifically, the implementation process of container service is as follows: the requirement to host is physical machine or virtual machine, operating system For linux6 or more version, container selects docker；

The load balancing module of container service component, control module, task scheduling modules, memory management module, network management mould Block, computing module and Container Management module are independent application programs, and are mounted on host, container mirror image warehouse and DNS module is independent application program, and is run in a mirror-image fashion in a reservoir；

Container service component is divided into two parts of control node and calculate node from deployment, and control node includes at least needing 2 Platform host, control node include load balancing module, control module, task scheduling modules, memory management module, network management Module.Calculate node includes computing module, Container Management module, memory management module and network management module, DNS module and appearance Device mirror image warehouse module is run in a manner of container instance in 1 or 2 calculate nodes wherein, and instance number can carry out on demand Configuration；

Container service is logically divided into service, deployment unit and three layers of container for a user；

Service is a series of interface of functions combination that provides to meet business demand, and service includes internal services and external clothes Business, internal services are that the service of standalone feature is provided for internal module, and external service is for third party devices such as core network elements The service of offer；

Deployment unit is the one or more application program that independently can be disposed and run and necessary configuration file, deployment unit A corresponding container mirror image, deployment unit is user's designed, designed, for a simplest example: in order to demonstrate intelligent network SCP All modules can be accomplished a deployment unit by basic function, and in production environment then be designed to each module solely Vertical deployment unit；

Container is the carrier of container service running example, the host of container instance operation be it is uncertain, by task schedule mould Root tuber is according to stock assessment and equilibrium of stock algorithms selection host, when container instance is abnormal collapse in the process of running, control Molding block can attempt restarting container instance, other hosts can be moved to if restarting failure, therefore container instance is forever Storing data must carry permanently stores volume on host by memory management module long；

It realizes that container mirror image warehouse is one warehouse of creation on the basis of container service, is used to press version management container mirror image, and Http service is provided；

Realize configuration center be to lay the foundation for automatically dispose, the step for need matching each software module of intelligent network SCP Set centrally stored to configuration center, software obtains automatically from configuration center configure after actuation, and is not being weighed by subscribing mechanism The software module of the case where opening real-time update software configuration, intelligent network SCP cannot directly be run after actuation, overwhelming majority operation Parameter needs to be set according to running environment in deployment, and configuration center also ensures after container instance exception through mirror image weight The example built uses newest configuration；

Specifically, the implementation method of configuration center is as follows:

Configuration center is to realize that user side is B/S framework, and intelligent network SCP side is C/S framework using B/S+C/S framework.In configuration The heart includes that WEB front-end, the rear end WEB, database and Client Agent (operate in each container instance of intelligent network SCP from top to bottom In)；

WEB front-end provides visual configuration management, is logically divided into service, module and three layers of configuration item for a user, The service for servicing and operating on container service is the same meaning (such as: intelligent network SCP), and module is that cloud service is included Software module, configuration item are being collectively referred to as configuration name, explanation and Configuration Values, and a service includes multiple modules, a module packet Containing multiple configuration items；

Client Agent periodically can pull configuration from the rear end WEB, can also work as configuration variation to WEB Back-end subscriptions configuration item When Client Agent is configured to by the rear end WEB active push, the configuration of Client Agent call instruction row online updating.Therefore intelligence The net each software module of SCP component requires that command line mode dynamic is supported to update configuration.

The load that SCP is statelessly transformed when being to solve the problems, such as elastic telescopic under High Availabitity and adaptation micro services framework is equal Weighing apparatus mechanism, by call state (including numbers of calling and called parties, calling time started, called party answer time etc.), session information and affairs State is centrally stored into the caching with persistence function, guarantees that the different messages of the same calling pass through different container instances Or process can be handled correctly.

The implementation method that SCP is statelessly transformed is as follows:

It not is to remove state, but stateful data are stored to distributed session cache module that SCP, which is statelessly transformed, In.State is necessary for call business, including in connecting, ring, response, call neutralize the states such as on-hook, in SCP When stateless transformation, need this kind of data being transferred to distributed session cache module from the memory of original application program.

It is that the read-write mode of call information is transformed that SCP, which is statelessly transformed, and call information includes: numbers of calling and called parties, calling The information such as the type that time started, response time, hang time, the subscription data of user and last time are requested, the side of realization Method substep is described as follows:

Calling unique identification is extracted when calling starts as key, Call-ID parameter is extracted to Session Initiation Protocol, to INAP or ANSI_ MAP protocol extracts dialogID parameter；

Serializing and unserializing method are increased to the relevant data structure of call information, sequencing method is by the data in memory It is encoded to byte stream, byte stream is decoded as the data structure in memory by unserializing method；

When saving call information, calling sequence method obtains byte stream as value, and session cache is written in key and value Module；

When reading call information, value is obtained from session cache module according to key, and call unserializing method to obtain value To data structure；

Increase session cache module, single-point operation should be avoided, the characteristics of it is big to meet data storage capacity, low delay, uses mesh herein Preceding widely used open source redis software.
