Engineering Contradiction Analysis
1Productivity
If data packets are transmitted without compression across the network, then network device complexity is reduced and ease of operation is improved, but bandwidth consumption increases and network throughput decreases
Solution Approach 1:
The patent introduces an intermediary compression module that acts as a mediator between the data source and destination. This module selectively compresses packets using algorithms like DEFLATE or LZ77 before transmission, and decompresses them at the receiving end. The intermediary handles the complexity of compression/decompression operations, allowing the core network infrastructure to remain simple while achieving improved throughput through reduced bandwidth consumption.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting packet representation through compression algorithms. By transforming data from its original format to a compressed format (changing the density and size parameters), the system reduces the amount of bandwidth required for transmission. The compression ratio varies based on packet content, allowing adaptive optimization of throughput while managing the complexity of the compression process.
2Quantity of substance
If compression algorithms are applied to all packets, then bandwidth requirements are reduced and network congestion is alleviated, but processing time increases and device complexity increases
Solution Approach 1:
The patent implements partial action by selectively applying compression only to packets that benefit from it, rather than compressing all packets uniformly. The system identifies suitable packets for compression based on their characteristics and applies compression algorithms only to those cases where compression will reduce size. This partial application of compression reduces overall data volume and congestion while minimizing the processing time overhead associated with compression operations.
3Productivity
If selective compression is implemented based on packet analysis, then bandwidth efficiency is improved and congestion is reduced, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring compression parameters, algorithms, and selection criteria before actual packet transmission begins. The system establishes compression policies, selects appropriate algorithms (such as DEFLATE, LZ77, or IP Payload Compression Protocol), and sets up the necessary data structures and lookup tables in advance. This preliminary preparation reduces the complexity of real-time packet analysis by having predetermined rules and configurations ready, allowing the system to make quick compression decisions based on pre-established criteria rather than analyzing each packet from scratch.
Data Source
AI summary
A network having traffic shapers or controllers to convey packets between a sender and receiver over first and second channels of a network. A compression and decompression module associated with the sending traffic shaper or controller compresses, marks, and forwards packets to the receiver over the second channel when the packet is compressible, as determined by size reduction. A compression and decompression module associated with the receiving traffic shaper identifies marked data packets sent over the second channel and, in response thereto, decompresses and forwards the packets to the receiver.
