Protocol-Specific Network Packet Processing via Virtual Queues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network processing systems face inefficiencies as CPUs need to continuously load different code to process packets of various protocols, leading to increased load and reduced performance.
Innovation Solution
Implementing virtual network stacks and temporary data structures configured to process specific protocols or groups of protocols, allowing for offloading certain packet processing tasks to network processing units (NPUs), thereby reducing the CPU's load and improving efficiency.

Engineering Contradiction Analysis
1Device complexity
If a single serialization queue is used to process multiple protocols, then device complexity is reduced, but processing efficiency deteriorates due to continuous code loading
Solution Approach 1:
The patent divides the single serialization queue into multiple protocol-specific serialization queues, where each queue is dedicated to processing packets of a specific protocol. This segmentation allows the system to avoid loading different code for different protocols on the same queue, thereby improving processing efficiency while maintaining manageable complexity through organized separation.
2Productivity
If protocol-specific processing is implemented, then processing efficiency improves, but device complexity increases due to multiple data structures
Solution Approach 1:
The patent creates a mapping relationship between multiple protocol-specific temporary data structures and multiple protocol-specific serialization queues, where each data structure can serve its corresponding queue. This universal mapping mechanism allows the system to handle multiple protocols efficiently without requiring entirely separate processing paths, thus improving efficiency while controlling complexity through a unified mapping approach.
3Productivity
If multiple serialization queues are created for different protocols, then processing efficiency improves, but ease of operation deteriorates due to complex packet routing
Solution Approach 1:
The patent introduces a mapping mechanism as an intermediary between the classifier and the protocol-specific serialization queues. This mapping acts as a mediator that automatically routes packets to the appropriate queue based on protocol type, eliminating the need for complex manual routing logic and making the system easier to operate while maintaining the efficiency benefits of protocol-specific queues.

AI summary
A system that includes a network interface for receiving a packets from a network, a classifier operatively connected to the network interface that analyzes each of the packets and determines to which temporary data structure to forward each of packets, wherein the classifier analyzes each packet to determine with which of a plurality of protocols the packet is associated with. Each temporary data structure within the system is configured to receive packets from the classifier, wherein each of the temporary data structures is associated with at least one virtual serialization queue and wherein each of the temporary data structures is configured to store packets associated with at least one of the plurality of protocols. The at least one virtual serialization queue is configured to queue packets from the one of the temporary data structures associated with the at least one virtual serialization queue.
