Solution Overview
Problem
Conventional IP flow mediation methods experience data loss when processing high-speed IP traffic exceeding multiple gigabits per second due to the large volume of data exceeding the processing capabilities of traditional servers.
Innovation Solution
A high-speed IP flow mediation apparatus utilizing a Network Processor (NP) board integrated into a server, which collects, analyzes, and transfers IP flow information without loss, employing high-speed processing capabilities for efficient data handling and minimizing physical space and cost through the use of a programmable NP board fitted into a PCI slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional IP flow mediation methods are used with traditional servers, then system cost and complexity are reduced, but data processing speed becomes insufficient for high-speed lines exceeding multiple gigabits per second, resulting in data loss
Solution Approach 1:
The system divides the data processing function into two segments: a Network Processor board that handles high-speed data collection and initial processing, and a server that performs detailed analysis. This segmentation allows the NP to filter and prioritize data at line speed, preventing data loss while reducing the server's processing burden.
Solution Approach 2:
The Network Processor board acts as an intermediary between the high-speed network line and the analysis server. It receives raw flow information at high speed, performs initial filtering and formatting, then transfers only necessary data to the server, thereby maintaining data integrity while enabling high-speed processing.
2Reliability
If a Network Processor board is introduced to enable high-speed lossless data processing, then data processing capability and lossless transfer are improved, but device complexity and system cost increase
Solution Approach 1:
The Network Processor board is designed to perform multiple functions: high-speed data collection, flow information generation, initial filtering, and formatted data transfer. By consolidating these functions into a single multi-functional device, the system achieves reliable lossless data transfer while minimizing the number of separate components needed.
Solution Approach 2:
The Network Processor board autonomously performs data collection, processing, and filtering without requiring constant server intervention. It independently manages the high-speed data stream and only engages the server when necessary for detailed analysis, thereby reducing overall system complexity despite adding specialized hardware.
3Speed
If CPU speed is improved to process high-speed data, then processing capability increases, but data loss still occurs on high-speed lines due to the overwhelming volume of input flow information
Solution Approach 1:
The Network Processor board performs preliminary actions by collecting, filtering, and formatting flow information before it reaches the server. This preliminary processing reduces the volume of data requiring high-speed CPU processing, allowing the server to handle analysis tasks efficiently without being overwhelmed by raw high-speed data streams.
