Network Monitoring Device Buffering for Data Reconciliation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed network monitoring environments, network devices provide status data at different intervals and formats, causing reconciliation difficulties for monitoring devices, which can lead to delayed or incomplete status data reporting, affecting the ability to handle requests and perform other tasks efficiently.
Innovation Solution
A network monitoring device maintains a buffer to store status data from various network devices, assigns time stamps to ensure accurate clock tick association, and manages communication to handle differing data types and frequencies, ensuring timely and coherent data reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network devices provide status data at different intervals and formats, then data collection coverage is improved, but data reconciliation difficulty increases
Solution Approach 1:
The patent introduces a buffer as an intermediary component between network devices and the monitoring system. The buffer receives status data from multiple network devices with different data intervals and formats, temporarily stores them, and manages the reconciliation process. This intermediary absorbs the complexity of handling diverse data sources, allowing the system to maintain high adaptability while reducing the direct reconciliation burden on the monitoring logic.
2Measurement precision
If status data is stored in a buffer with time stamps, then data accuracy is improved, but system resource usage increases
Solution Approach 1:
The patent applies preliminary action by assigning time stamps to status data at the moment of buffer insertion, before the data is processed or retrieved. This pre-tagging approach ensures accurate temporal association without requiring complex time-correction logic later. The time stamp is attached in advance when the data arrives, simplifying subsequent data retrieval and analysis while maintaining high measurement precision.
3Stability of the object's composition
If communication is managed to handle differing data types and frequencies, then data coherence is improved, but processing time increases
Solution Approach 1:
The buffer operates continuously to receive, store, and manage status data from network devices with differing data types and frequencies. By maintaining a continuous data collection and storage operation, the system ensures that all incoming data is captured without gaps, preserving data coherence. The buffer's continuous operation allows data to be accumulated and reconciled at a steady pace, reducing peak processing times while maintaining overall data coherence.
Data Source
AI summary
A monitoring device responds to status data pushed from a network device, and also manages a link with another network device, the link allowing the monitoring device to pull status data from the second network device. The monitoring device receives packets including status, the data indicating activity for one or more clock ticks. The monitoring device can compute statistical measures, rather than the network device. The monitoring device maintains the status data in a buffer. The monitoring device lags actual activity, but has is more likely to capture delayed packets. The network device sends packets as wrappers, each wrapper indicating sets of status information. When the information in a wrapper crosses a clock tick boundary, the monitoring device allocates reported activity among clock ticks, assuming that activity follows a uniform distribution.
