Detailed Description
The technical solutions of the present application will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The existing communication system based on the FreeWITCH server has the problems of single-point fault and weaker concurrent processing capacity. By increasing the hardware configuration solution, the cost is expensive and always reaches an upper limit, and flexible unlimited expansion cannot be supported, and the state machine to be maintained is too complex since the amount of binding on FreeSWITCH is very much, while FreeSWITCH is a B2BUA (Back-to-Back User Agent). Because of more concurrent demands and single machine performance bottlenecks, reliability and performance bottlenecks need to be improved through clustering, and resources can be effectively utilized. Based on the above, the load balancing communication system, the method, the device, the server equipment and the storage medium provided by the embodiment of the application can solve the problems of single-point failure and weaker concurrent processing capacity by combining the multi-node proxy server with the multi-node FreeWITCH server.
For the sake of understanding the present embodiment, a detailed description will be given of a load balancing communication system disclosed in the embodiment of the present application.
Referring to a schematic diagram of a load balancing communication system shown in fig. 1, the load balancing communication system includes a proxy server 101 deployed by multiple nodes and a server cluster formed by FreeSWITCH servers 102 deployed by multiple nodes.
The proxy servers 101 are used to provide registration functions for clients, and each proxy server 101 shares registration data.
The proxy server 101 is further configured to distribute dial signaling of the first client to different FreeSWITCH servers 102 in the server cluster; the FreeSWITCH server 102 in the server cluster is configured to call the second client when receiving the dialing signaling, and send a response message returned by the second client to the proxy server 101; the proxy server 101 is further configured to return a response message sent by the FreeSWITCH server 102 in the server cluster to the first client, so as to establish a communication connection between the first client and the second client.
The FreeSWITCH server 102 is also used to forward the media data stream between the first client and the second client that establish the communication connection.
It should be noted that, the three proxy servers 101 and the three FreeSWITCH servers 102 shown in fig. 1 are only examples, and the number of proxy servers 101 and the number of FreeSWITCH servers 102 may be set according to actual requirements, and the number of proxy servers 101 and the number of FreeSWITCH servers 102 are not limited in the present application.
The first client and the second client are clients that have completed registration, the clients register in any proxy server 101, the registration data is stored in a database, and the registration data is synchronized to other proxy servers 101 through the database, and the FreeSwitch server 102 shares the registration data through the database to perform identity verification. For ease of distinction, the calling party will be referred to herein as the first client, and the called Fang Chenwei second client. Because of the greater concurrent demands and the greater number of single-machine mounts, the embodiment of the application adopts a multi-machine mount scheme to realize the relative load balancing, namely adopts the multi-node proxy server 101 and the multi-node FreeWITCH server 102 to realize the relative load balancing.
According to the load balancing communication system provided by the embodiment of the application, the proxy servers of the multiple nodes are deployed, the proxy servers distribute dialing signaling to the FreeWITCH servers of the multiple nodes for processing, and even if the proxy servers of some nodes fail, as each proxy server shares registration data, the registration data of a user cannot be lost, and a request sent by a client can still be processed, so that the problem of single-point failure is solved; the throughput of the media data stream is improved by deploying the multi-node FreeWITCH servers, all the registrations are responsible for the proxy servers, the media data stream is managed by the FreeWITCH servers, the multi-node proxy servers and the multi-node FreeWITCH servers are combined to realize the relative balance of loads, and perfect and reliable SIP call service is provided for users, so that the problem of weaker concurrent processing capacity is solved.
Alternatively, the proxy server 101 may be a Kamailio server. Kamailio is a high performance SIP server that adopts a modular architecture, making the system easily scalable; the Kamailio server can also realize data sharing; the FreeSWITCH server is relatively stiff and difficult to handle in terms of the handling of signaling, while the Kamailio server is more flexible and easier to handle.
A kamalio-based server may implement VoIP (Voice over Internet Protocol, voice over IP) load balancing and registration agents. Proxy SIP using Kamailio servers and distribute traffic and content; all registration is performed by the Kamailio server, media is managed by each FreeSWITCH server 102 (i.e., the Kamailio server is mainly responsible for signaling flows, the FreeSWITCH server 102 is mainly responsible for media data flows), the FreeSWITCH servers 102 share registration data by means of databases or memory databases, etc., and when a call is entered, the registration data is distributed to each different FreeSWITCH server 102 for answering or each FreeSWITCH server 102 directly sends the registration data.
Optionally, the load balancing communication system further includes a MySQL database, where the MySQL database is used to store registration data, and the FreeSWITCH server 102 shares the registration data through the MySQL database.
For ease of understanding, one possible implementation procedure of the above-described load balancing communication system is as follows:
1. ACL (Access Control Lists, access control list) of FreeSWITCH servers is configured, access whitelist of Kamailio servers is configured. Exemplary codes are as follows:
in autoload_configs/acl.conf.xml
<list name＝"domains"default＝"deny">
< node type= "allow" cidr= "server address of Kamailio"/>
</list>
2. And configuring a MySQL database. Exemplary codes are as follows:
configuration using MYSQL as storage database, edit etc/kamailio/kamctlirc, add DBENGINE = MYSQL
Creating a database of kamailio, kamdbctl create
kamailio increases account number kamdbctl add username password
The kamailio server uses a dispatcher module to balance loads, configures the dispatcher module, and the exemplary code is as follows:
load balancing dispatcher module for/(and defined) switch
#！define WITH_LOADBALANCE
The// load module, note the last to put to all loadmodules
#！ifdef WITH_LOADBALANCE
loadmodule"dispatcher.so"
#！endif

#！endif
4. The request_route portion is configured, and exemplary key information is as follows:
the configuration is completed in all Kamailio servers and FreeWITCH servers, and subsequent load balancing communication can be performed after the configuration is completed. The dispatcher module is a message distribution center, and all received messages pass through the module and are forwarded to the corresponding processing module by the module; the dispatcher module can be configured in a self-defined manner, and can configure service routing rules according to service scenes, including configuration of Record-Route header fields.
For easy understanding, the working principle of the load balancing communication system described above will be described in detail with reference to fig. 2.
As shown in fig. 2, two proxy servers, nminx Kamailio (i.e., load balancing Kamailio servers), a server cluster including three FreeSWITCH servers, and a MySQL database that provides global shared registered user information (i.e., provides shared registered data), the calling party being mobile user a, and the called party being mobile user B are shown.
1. Registration
Taking the registration of the mobile phone user A as an example, the mobile phone user A sends a register SIP signaling to any proxy server through an SIP gateway, the proxy server performs identity verification on the SIP information, and if the verification is successful, the registration data is written into a MySQL database. Other proxy servers periodically synchronize the registration data in the MySQL database.
2. Dialing number
The mobile phone user A dials, the dialing signaling firstly reaches any proxy server, when Authentication is passed, if a called party (such as the mobile phone user B) is online, the proxy server forwards the Authentication to the FreeWITCH server, the FreeWITCH server enters a dialplan state to search, and then a series of actions to be executed are determined, such as sending an incoming call notification to the mobile phone user B through a service customized APP call interface service, otherwise, the calling party telephone is directly hung up.
3. Answering machine
When the Record-Route header field is configured in advance, when the proxy server receives a SIP message, the Record-Route header field can determine whether to reserve a SIP transaction, that is, whether a subsequent SIP message still passes through the proxy of the proxy server, and when the Record-Route header field information is configured, a called party (such as a mobile phone user B) can send the SIP message which is determined to answer to the proxy server again, and then the proxy server routes the SIP message to a calling party (such as the mobile phone user a).
If the Record-Route header field is not configured in advance, the called party will send the SIP message that determines answering directly to the calling party, and in practical application, a situation that the call can be switched on but the ACK or BYE message is not received (this situation often occurs, especially in the network with NAT (Network Address Translation, network address translation)) may be encountered, and it is necessary to check whether the Record-Route or Contact header field in the transaction is correct. The Contact header field is used for determining a returned client address; the priority of Record-Route is higher than that of Contact, and when Record-Route does not exist, address information in Contact is directly used as destination address information.
RTP (Real-time Transport Protocol ) stream
The RTP media data stream in the conversation process directly bypasses the proxy server, is directly sent to the FreeWITCH server through the terminal (such as a mobile phone user A), and is forwarded to the terminal at the other end (such as a mobile phone user B) through the FreeWITCH server.
The embodiment of the application also provides a load balancing communication method which is applied to the load balancing communication system, and referring to a flow diagram of the load balancing communication method shown in fig. 3, the method mainly comprises the following steps:
in step S301, the first client sends registration signaling to the proxy server.
In step S302, the proxy server performs authentication on the SIP information in the registration signaling.
In step S303, the proxy server writes the registration data in the registration signaling into the database when the authentication is successful.
In step S304, the proxy server periodically synchronizes the registration data in the database.
In step S305, the first client sends a dial signaling to the proxy server.
In step S306, the proxy server distributes the dial-up signaling to the different FreeSWITCH servers in the server cluster.
In order to realize that the SIP message sent by the second client and determined to answer is forwarded to the first client via the proxy server, in this embodiment, the proxy server configures header field information of the Record-Route header field in the dialing signaling, and distributes the configured dialing signaling to different FreeSWITCH servers in the server cluster.
In step S307, the FreeSWITCH server enters a dial plan state for searching.
In step S308, the FreeWITCH server calls the second client.
In step S309, the second client returns a response message to the FreeSWITCH server.
In step S310, the FreeSWITCH server sends a response message to the proxy server.
In step S311, the proxy server returns the response message to the first client. A communication connection between the first client and the second client is thus established.
In step S312, the FreeSWITCH server forwards the media data stream between the first client and the second client.
