Packet Distribution Core Selection via Decryption Hashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As packet-based telecommunications networks experience increasing volumes, bottlenecks arise in components that analyze packets for routing, leading to significant processing efforts and delays due to repeated access and use of packet headers by multiple devices along the network path.
Innovation Solution
Generating a header hash from identifiers in the packet header during decryption and using it to distribute packets among multiple processing cores for further processing and routing, reducing the need for direct access to the larger identifiers and minimizing processing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple devices along the network path each perform access and use of the packet header, then routing decisions can be made at each device, but processing effort and delays become significant as packet volume scales
Solution Approach 1:
The patent extracts only the essential identifier information from the packet header and creates a simplified representation (hash value) that can be processed efficiently. Instead of each device accessing and analyzing the complete header, the system extracts minimal necessary information for routing decisions, reducing processing overhead while maintaining routing capability.
Solution Approach 2:
The patent transforms the packet header information through a hash function, changing the parameter representation from the original header format to a compact hash value. This parameter transformation enables faster comparison and matching operations at each network device, improving processing throughput while preserving the ability to make routing decisions based on destination identification.
2Measurement precision
If complete packet headers are accessed and processed by each device, then accurate routing information is obtained, but processing resources and time are significantly consumed
Solution Approach 1:
The patent creates a copy of the essential routing information in the form of a hash value that can be quickly generated and compared. Instead of processing the complete original header at each device, the system uses this copied representation to make routing decisions, significantly reducing processing time while maintaining routing accuracy through proper hash table matching.
3Quantity of substance
If packet volume through the network continues to scale up, then network capacity increases, but processing effort and delays from header analysis become significant bottlenecks
Solution Approach 1:
The patent segments the packet processing task into two distinct parts: (1) generation of a compact hash value from the packet header at the source, and (2) efficient matching of this hash value against hash tables at intermediate devices. This segmentation allows each device to handle only the simplified hash matching operation, reducing processing complexity and enabling the network to scale to higher packet volumes without proportionally increasing device complexity.
