Optical Line Terminal Configuration Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication systems, the time taken for communication traffic to start after an optical network unit (ONU) links up is prolonged due to the need for the optical line terminal (OLT) to obtain and transmit configuration information from a management server, especially when multiple ONUs link up simultaneously, leading to delays in providing communication services.
Innovation Solution
The optical line terminal implements an obtaining unit to retrieve configuration information from another apparatus and a configuring unit to transmit this information to ONUs, with both processes prioritized based on the ONU's priority, allowing the OLT to manage the configuration process efficiently even when multiple ONUs link up at the same time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the optical line terminal obtains configuration information from a management server for each ONU sequentially, then the configuration information can be obtained accurately, but the time required for communication traffic to start flowing increases significantly
Solution Approach 1:
The patent applies preliminary action by having the OLT obtain configuration information for all ONUs in advance before they actually need it. When multiple ONUs link up simultaneously, the OLT has already retrieved their configuration information from the management server, so it can immediately transmit the information without waiting for each ONU's configuration request, thereby reducing the time for communication traffic to start.
2Adaptability or versatility
If the optical line terminal processes configuration information for multiple ONUs that link up simultaneously, then all ONUs can be configured, but the processing time for each ONU increases due to sequential handling
Solution Approach 1:
The patent implements preliminary action by pre-obtaining configuration information for multiple ONUs before they link up. This allows the OLT to handle multiple ONUs simultaneously without sequential processing delays, as all configuration data is already available in the OLT's memory when the ONUs need it.
