Problems solved by technology

In order to overcome the respective shortcomings of these two structures, Funkhouser proposed a hybrid structure. Although it can better solve the problems of server bottlenecks and scene data distribution, it is difficult for the scalability and user-to-communication required in distributed virtual reality systems. The frequent dynamic changes of content seem helpless to solve these two problems

Embodiment Construction

[0011] Below in conjunction with specific embodiment, further illustrate the present invention.

[0012] 1. System communication topology design

[0013] In system construction, we use CBT (Core-basedTree) as the basic communication framework. In CBT, each participant can play the role of publisher and subscriber at the same time, and share a multicast tree. At the same time, any participant connected through CBT can communicate, and the flow of ordering or publishing data is different. It is arbitrary and belongs to a bidirectional shared multicast tree structure. CBT is not only simple in structure and easy to expand, but also can effectively reduce the storage scale on the active router compared with the communication structure of SBT (Source-basedTree). At the same time, this structure is combined with the publish-subscribe model. Objects can simply send new subscription information to the router at any time, thereby changing the communication relationship. Therefore, th...

Abstract

The invention discloses a distributed virtual reality system network construction method. Through integration of such technologies as a reference publishing / order mode, a multicast router algorithm, an active network technology and the like, by use of a CBT-based bidirectional sharing multicast tree as a network topology structure, the requirements for reducing a router information storage quantity and rapidly dynamically changing communication relations are satisfied; by use of a router protocol supporting interest management, active filtering and forwarding can be performed according to content of a data packet such that the system network load is reduced; and by use of a rapid router matching algorithm, the data packet forwarding efficiency of a router is improved.

Description

technical field [0001] The invention relates to a virtual reality technology, in particular to a scalable distributed virtual reality system network construction technology. Background technique [0002] The distributed virtual reality system combines virtual reality with network communication, provides a shared virtual space to support the simulation of objects and the interaction and communication of multiple distributed users. Although the speed of the network and the processing power of the mainframe have been continuously improved in recent years, when there are a large number of users and objects in the virtual reality system, even if each user only needs a small amount of bandwidth, the cumulative communication needs of thousands of users must exceed the network. In the heterogeneous WAN, the access speed of each user and the processing capacity of the host are different. A slow host will inevitably affect the response speed of other hosts and even reduce the response...
