Network Slot Synchronization for Dynamic Bandwidth Adjustment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Inconsistent slot adjustments between receiving and sending ports in a communication network lead to buffer overflow and service interruption due to asynchronous slot adjustment commands, especially when there are significant changes in client service bandwidth.

Innovation Solution

A method for dynamically adjusting the number of slots by synchronizing slot adjustments across devices using slot adjustment indication signals and correspondence relationships, ensuring consistent slot adjustments at both receiving and sending ports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If slot adjustment commands are transferred to different devices at different time points, then bandwidth adjustment can be performed dynamically, but slot adjustment inconsistency occurs between receiving and sending ports

Engineering Contradiction:

Improvebandwidth adjustment capabilityVSAvoidslot adjustment consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary slot adjustment preparation before the actual adjustment takes effect. When a slot adjustment command is received, the device prepares the slot configuration in advance and only applies the adjustment after confirmation, ensuring that both receiving and sending ports are synchronized before bandwidth changes are implemented.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism where slot adjustment commands are acknowledged by receiving devices and confirmed by sending devices. The sending device waits for confirmation that the receiving device has completed slot preparation before finalizing the adjustment, ensuring consistency across the communication link.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If slot adjustment is performed asynchronously on different devices, then bandwidth can be flexibly adjusted, but buffer overflow occurs due to slot inconsistency

Engineering Contradiction:

Improvebandwidth flexibilityVSAvoidbuffer overflow

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The receiving device performs slot adjustment preparation in advance upon receiving the adjustment command, configuring its slot structure before the sending device applies the same adjustment. This preliminary configuration ensures that when data transmission resumes, both ends have consistent slot structures, preventing buffer overflow.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system buffers slot adjustment commands and prepares slot configurations before actual data transmission resumes. By cushioning the adjustment process and ensuring both devices are ready beforehand, the system prevents harmful buffer overflow conditions that would occur with asynchronous adjustments.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If the number of slots is adjusted dynamically, then bandwidth can adapt to service volume changes, but service interruption occurs due to timing inconsistency

Engineering Contradiction:

Improvebandwidth adaptabilityVSAvoidservice continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system uses feedback confirmation to ensure service continuity during bandwidth adjustment. The receiving device sends acknowledgment when slot preparation is complete, and the sending device waits for this confirmation before applying the adjustment and resuming data transmission, preventing service interruption caused by timing inconsistencies.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Slot adjustments are prepared in advance on both receiving and sending devices before data transmission resumes. This preliminary configuration ensures that when the adjustment takes effect, both ends are synchronized, allowing bandwidth to adapt to service volume changes without interrupting client services.

Inventive Principle:

Principle #10Preliminary action
