Detailed Description
In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.
A dynamic load balancing method as shown in fig. 1 and 2 includes the following steps:
s1: judging the service object, if the single data volume of the service object is small, the request is frequent, and the concurrency requirement is high, entering step S2, if the data traffic of the service object is large, the interactive process is less, and the requirement on the network is high, entering step S3;
s2: a signaling load balancing method is adopted;
s3: a media service load balancing method is adopted.
The signaling service mainly serves scenes with small single data volume, frequent requests and high concurrency requirements, such as HTTP service and SIP signaling service, and for the type of service, the least connection and the fastest mode, namely the observer mode, are adopted for load balancing. Meanwhile, in order to ensure high availability, a dual-standby or multi-standby structure is required on a hardware level to ensure that efficient and stable service is provided when a server is down.
The user initiates access, the router accesses the main and standby servers of the routing gateway, then the routing gateway allocates signaling service according to the algorithm, and returns the address result of the allocation processing server.
And if the main routing equipment node fails, the standby routing node takes over the work through the floating IP. To ensure that service is not interrupted.
A state reporting mechanism is arranged between the routing nodes and the service, the reported content comprises the number of connections, the response speed and performance parameters (CPU, memory, network and the like), the routing nodes judge through the information, and then the task is distributed to fall on a specific idle server for processing.
The load balancing and high availability of the signaling service are completed through the above contents.
The media service is characterized by large data flow, less interactive process and high requirement on network. The single machine has limited processing capacity, and the simple adoption of the observer mode for load balancing aiming at the service of the type is not enough to meet the stable and efficient transmission of data.
The user initiates access, the router accesses the main and standby servers of the routing gateway, the routing gateway distributes media services according to the algorithm, and returns the address result of the distribution processing server.
And if the main routing equipment node fails, the standby routing node takes over the work through the floating IP. To ensure that service is not interrupted.
After the media server pulls the data stream according to the request, the media server distributes the data to the client and simultaneously synchronizes information to all CDN nodes through CDN information, but data distribution is not performed, so that a visitor can conveniently and quickly access the data.
When a visitor accesses the data stream through the gateway, the gateway distributes service according to the state information of the media service, if the service is distributed to the stream taking server, the service is directly returned to the normal stream taking of the service, if the load of the stream taking server is high, the distributed other servers perform service, and the distributed server needs to take the stream to the stream taking node and then distribute the stream. The data source is ensured to have only one path of data, and the load on the original equipment is reduced. And simultaneously balancing the loads of all nodes.
If one routing node fails, the processing mode is consistent with the signaling mode.
If the media service node has a fault, the stream fetching information on the service is distributed to other nodes through the routing node in time, and the user is informed that the stream fetching position is changed, and stream fetching change is carried out immediately, so that the stream information is ensured not to be interrupted. If the distribution node is in fault, the user is only required to be informed of the change of the stream taking position, and the stream is taken from the new address again.
In this embodiment, the proposed dynamic load balancing method can meet the requirements of different data streams, has a guarantee of high availability, and ensures that a high-efficiency and stable data transmission service is provided.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
