Configuration Subscription via Association Indication in SDN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing network operation and maintenance management systems, clients can only subscribe to configuration information of all node instances in a network, leading to low subscription efficiency as they receive unnecessary configuration information, making it difficult to efficiently manage configuration changes in Software Defined Networks (SDN) using the NETCONF protocol.
Innovation Solution
A configuration information subscription method and apparatus that allows clients to subscribe to specific configuration information of associated nodes by using first and second indication information in subscription request messages, enabling targeted subscription through association, thereby improving efficiency by receiving only relevant configuration updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a client subscribes to configuration information of all node instances in the network, then the client can obtain complete configuration data, but the subscription efficiency decreases due to receiving unnecessary configuration information
Solution Approach 1:
The patent segments the configuration information subscription by introducing indication information that divides the network nodes into two categories: nodes whose configuration information should be subscribed to and nodes that should be excluded. This segmentation allows the client to selectively subscribe only to relevant configuration information, improving subscription efficiency while maintaining completeness of necessary data.
Solution Approach 2:
The patent applies local quality by making the subscription behavior specific to different nodes based on the indication information. Instead of a uniform subscription approach for all nodes, the system tailors the subscription to local requirements of each node, subscribing to configuration information only for nodes that are relevant to the client's needs.
2Reliability
If a client subscribes to configuration information of all node instances, then all configuration changes are captured, but data processing overhead increases due to unnecessary data
Solution Approach 1:
The patent extracts and removes unnecessary configuration information from the subscription process by using indication information to identify and exclude nodes whose configuration changes are not needed. This extraction principle reduces the volume of data that needs to be processed while maintaining reliable detection of relevant configuration changes.
Solution Approach 2:
The patent applies partial action by subscribing to only the necessary portion of configuration information rather than all configuration information. The indication information enables the client to perform a partial subscription that covers exactly what is needed, avoiding the excessive action of processing unnecessary data while maintaining reliable configuration change detection for relevant nodes.
Data Source
AI summary
This application discloses a configuration information subscription method and apparatus. The method includes: a client obtains a subscription request message, where the subscription request message includes first indication information and second indication information, the first indication information is for indicating subscribed first configuration information, and the second indication information is for indicating subscribed second configuration information associated with the first configuration information; and sends the subscription request message to a server. According to the solution in this application, when subscribing to the first configuration information, the client can subscribe to the second configuration information through association, so that subscription efficiency of the configuration information is improved.
