Directory Tree Server Data Block Validation Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-party online games, the existing directory tree data downloading method wastes downlink resources as it issues all directory tree data, including locally stored data, even if it is identical to the server's data, preventing players from joining games if the client fails to download the data.
Innovation Solution
A method where the directory tree server and client generate IDs and validity IDs for data blocks according to an agreed protocol, with the server issuing data blocks only when the validity IDs differ, allowing for efficient resource management by avoiding redundant data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the directory tree server issues all directory tree data requested by the client, then the client can obtain complete directory tree data, but downlink resources of the server are wasted when the client already has identical locally stored data
Solution Approach 1:
The client performs preliminary actions by storing validity IDs of locally cached directory tree data blocks before making download requests. When requesting data, the client includes these validity IDs, allowing the server to pre-check whether the client already possesses the requested data without actually downloading it. This preliminary validation prevents redundant data transmission and conserves downlink resources.
Solution Approach 2:
The server implements a feedback mechanism by comparing the validity ID received from the client with the validity ID of the data block stored on the server. Based on this comparison feedback, the server determines whether to issue the data block or return a matching success message. This feedback loop enables intelligent resource allocation, issuing data only when necessary and avoiding waste of downlink resources.
2Reliability
If the client requests all directory tree data including locally stored data, then the client ensures it has the latest version, but unnecessary data transmission occurs when local data is identical to server data
Solution Approach 1:
The system changes the parameter representation of data blocks by using validity IDs (such as Hash values) instead of transmitting the actual data blocks for comparison. This parameter transformation allows the server and client to verify data consistency through comparing compact identifiers rather than large data sets, significantly improving data transmission efficiency while ensuring version consistency.
Solution Approach 2:
The invention extracts only the essential identifying feature (validity ID) from the complete data block and uses it for comparison purposes. Instead of transmitting or comparing entire directory tree data blocks, the system extracts and compares only the validity ID parameter, which is sufficient to determine whether data needs to be updated. This extraction approach maintains data version consistency while eliminating redundant data transmission.
3Ease of manufacture
If the server issues data blocks without checking local client data, then the implementation is simple, but downlink resources are wasted
Solution Approach 1:
The validity ID serves as an intermediary element between the client's local data and the server's data blocks. Instead of directly comparing large data blocks or implementing complex client-side verification, the system uses the validity ID as a mediator that enables efficient comparison and decision-making. This intermediary approach maintains implementation simplicity while preventing waste of downlink resources through intelligent data issuance.
Data Source
AI summary
A method, system, and server for issuing directory tree data and a client. The method includes: pre-storing Identities (IDs) for data blocks obtained by dividing directory tree data according to an agreed protocol, and generating and storing validity IDs for the data blocks according to the agreed protocol; receiving, by a directory tree server, an ID and a validity ID of a data block that the client requests to download, and querying for a validity ID of a data block having the same ID at a directory tree server side. If the validity ID of the data block having the same ID at the directory tree server side is the same as the validity ID received from the client, issuing a matching success message to the client; otherwise, issuing, a matching failure message and the data block at the directory tree server side having the same ID to the client.
