Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As communication networks grow in size, speed, and complexity, they face diagnostic challenges due to issues like out-of-order packets, inefficient routing, and excessive traffic, which existing diagnostic mechanisms struggle to efficiently address.
Innovation Solution
A networking system comprising a processor and memory with a routing module that reorders network messages by using a routing data structure, transaction data structure, and packet-route-to data to determine packet order and route them correctly, facilitating efficient communication and diagnostic functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If network bandwidth is increased to handle higher data rates, then network capacity improves, but packet ordering problems and diagnostic difficulties worsen
Solution Approach 1:
The patent applies preliminary action by inserting sequence numbers into packets before transmission and establishing routing rules in advance that automatically reorder packets at the destination. This pre-prepared ordering mechanism handles high-speed traffic without requiring complex real-time diagnostics, thus resolving the contradiction between increased network capacity and diagnostic difficulty
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of sequence numbers and routing rules that mediate between transmitted packets and their intended delivery order. This intermediary system automatically manages packet reordering without burdening the diagnostic system, allowing high network capacity while simplifying packet flow management
2Speed
If network speed is increased to meet bandwidth demand, then data transmission rate improves, but packet out-of-order delivery increases
Solution Approach 1:
The system applies preliminary action by embedding sequence numbers in packets before transmission and pre-configuring routing rules that specify reordering logic. This allows packets to travel at high speeds through the network while being automatically reordered at the destination based on their sequence numbers, maintaining both speed and reliability
Solution Approach 2:
The patent segments the packet flow management by assigning individual sequence numbers to each packet and using separate routing rules for different packet types. This segmentation allows independent tracking and reordering of packets, ensuring reliable delivery order even at high transmission rates
3Adaptability or versatility
If complex routing is implemented to handle network growth, then network adaptability improves, but routing inefficiency and excessive traffic worsen
Solution Approach 1:
The patent applies universality by creating routing rules that serve multiple functions: they identify packet destinations, manage reordering sequences, and handle different packet types through a unified rule-based system. This multi-functional approach provides network adaptability while maintaining routing efficiency through a single coherent mechanism
Solution Approach 2:
The system uses parameter changes by varying routing rule parameters based on packet characteristics such as sequence numbers and packet types. This allows the routing system to adapt to different network conditions and packet requirements while maintaining efficient processing through parameter-based decision making rather than complex structural changes
Data Source
AI summary
Systems for ordering network packets. In one example embodiment, a networking system includes a processor and memory. The memory has stored thereon a routing data structure, a transaction data structure, and first packet-route-to data. The processor is configured to receive a packet; to copy second route-to data from an entry in the routing data structure to the first packet-route-to data, the entry being associated with an identifier associated with the packet, the second route-to data comprising a value indicating that the packet should be routed back to the processor; to determine whether the packet is in order; to, when the packet is in order, copy third route-to data to the first packet-route-to data, the third route-to data comprising a value indicating that the packet should be routed to a destination; and to route the packet according to the first packet-route-to data.
