【摘要】：目的目前互联网上构建的虚拟世界规模越来越大,但在现实网络带宽有限的情况下,实时传输海量复杂虚拟场景一直都是难以解决的"瓶颈问题",针对该极具挑战性的问题进行了综述性研究。方法首先对大规模3维虚拟场景传输的主要技术进行了概述,然后分别对其中的关键技术如大规模虚拟场景的轻量化与流式化技术、P2P-Cloud(Peer to Peer-Cloud)网络架构、资源发现/邻居发现策略、不同网络架构的虚拟场景数据分发策略和移动网络场景传输等进行了详细综述。结果阐明了虚拟场景传输主要技术之间的关系,并通过对已有经典成果的对比,分析了它们的优缺点及需要解决的关键问题。结论分别从虚拟场景传输的场景预处理、基于云的混合网络架构和移动网络中的场景传输这3个发展方向做了前瞻性的展望。
[Abstract]:Objective at present, the virtual world built on the Internet is becoming larger and larger, but with the limited bandwidth of the real network, Real-time transmission of massive and complex virtual scenes is always a "bottleneck problem" which is difficult to solve. Methods firstly, the main technologies of large-scale 3D virtual scene transmission were summarized, and then the key technologies such as lightweight and streaming technology of large-scale virtual scene, P2P-Cloud (Peer to Peer-Cloud network architecture, resource discovery / neighbor discovery strategy, were discussed respectively. The virtual scene data distribution strategy and mobile network scene transmission with different network architecture are reviewed in detail. The results illustrate the relationship between the main technologies of virtual scene transmission and analyze their advantages and disadvantages as well as the key problems to be solved by comparing the existing classical results. Conclusion from the perspective of scene preprocessing of virtual scene transmission, cloud based hybrid network architecture and scene transmission in mobile network, this paper makes a prospective outlook.
