A method for routing, forwarding and processing of collaborative plotting messages based on surface blocks

Abstract

The present invention relates to the field of information technology, and aims to solve the problems of limited number of users, cross-network segments, real-time performance, etc. that the current plotting system related to the acquisition of surface-related information faces in order to realize the operation mode of collaborative plotting, and proposes a surface-based Cooperative plotting message routing, forwarding and processing methods of blocks. The present invention uses the surface area of ​​the task to construct a cooperative block and a message forwarding routing table, and proposes a processing method for cooperative messages forwarded based on this route, including unified forwarding and distributed analysis of messages, and editing conflict resolution for the same operation object , re-login data environment recovery, asynchronous transmission of large-scale message content, automatic update of message routing, etc., can forward effective messages in real time in the wide area network, and provide solutions for multi-user collaborative plotting operation data while improving network resource utilization A complete solution to the consistency problem to achieve the goal of real-time collaborative plotting in the Internet, multi-user, and high-concurrency environments.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a surface block-based collaborative plotting message routing forwarding and processing method. Background technique [0002] The current plotting system that involves the acquisition of surface-related information, such as various surveying, mapping, editing and mapping software systems, remote sensing information mapping systems, geographic information systems, etc., realizes the operation mode of collaborative plotting (that is, multi-user and multi-client collaboration) methods can basically be classified into the following two categories: [0003] 1. The information obtained by each plotting information acquisition client is uniformly accessed in the form of database records on the central server. The client that needs this information for collaborative work reads the information from the database, displays and processes it, and writes the processed results back to the ...

Problems solved by technology

[0006] In the first method, the data stored in the central database can only be obtained by the client actively initiating a request. Therefore, the interactive operation of the collaborative work system can only be quasi-real-time, and the real-time degree of synchronous data depends on the setting of client access. The frequency of the database, when the number of collaborative work clients online at the same time is large, the access efficiency will drop significantly; When the user edits the same data, timing conflicts will occur

Therefore, this method is only suitable for the situation where the content of the collaborative plotting task is independent, that is, each client is required to only edit the content collected by itself

[0007] The second type of method, because of the broadcast mode, the message crossing the gateway will cause technical problems, so it is only suitable for the LAN environment, not suitable for deployment in the Internet environment

In the broadcast mode, all users in the network can receive the information, and users who do not need the information will also be affected. The utilization rate of network resources will be very low, the bandwidth waste will be serious, and the amount of messages will increase exponentially with the number of users. It is easy to cause a broadcast storm and cannot be applied to the situation where there are many users

At the same time, due to the existence of network delay, the order in which each client receives messages may be inconsistent with the time order of each client's actual operation. When multiple users edit the same data, timing conflicts will also occur
