Solution Overview

Problem

Current core network devices lack dual-end transparent TCP acceleration capabilities, requiring kernel-level modifications and complicating the setup and configuration of TCP acceleration for data senders and receivers.

Innovation Solution

Implementing a TCPO acceleration module in the core network element to cache data packets, determine a target window mode based on the receiving end's window field value, and send ACK responses to the sender without waiting for a response from the receiver, thereby optimizing data transmission.

VSEngineering Contradiction Analysis

1Productivity

If TCP acceleration is implemented based on congestion control algorithm, then data transmission efficiency is improved, but device complexity increases due to kernel-level configuration requirements

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidkernel-level configuration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a core network device as an intermediary between the data sender and data receiver. This intermediary device performs TCP acceleration functions by caching data packets and managing window field values, eliminating the need for kernel-level modifications on end devices. The core network device acts as a mediator that handles the complex TCP optimization logic centrally, thereby improving data transmission efficiency without increasing complexity at the edge devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the TCP acceleration functionality from the end devices (senders and receivers) and relocates it to the core network device. By taking out the complex congestion control algorithm implementation and window management from the kernel level of end devices, the system achieves transparent acceleration without requiring modifications to the end devices. The core network device independently handles packet caching and response generation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 1:

The core network device performs self-service by autonomously managing the TCP acceleration process. It automatically caches incoming data packets, determines appropriate window field values based on its own judgment of receiver capabilities, and generates response messages without requiring external configuration or intervention. This self-service mechanism maintains transparent operation for end devices while internally optimizing data transmission efficiency through intelligent packet management.

Inventive Principle:
Principle #25Self-service

Solution Approach 1:

The core network device serves as a mediator that enables dual-end acceleration without requiring configuration on either end device. The intermediary handles all acceleration logic centrally, including caching packets from the sender side and managing window field values for the receiver side. This centralized mediation approach achieves the benefits of dual-end transparent acceleration while maintaining operational simplicity, as no setup or configuration is needed at the end devices.
