移动互联网的开发导致视频流量数据的形状增加。新的移动边缘计算（MEC）技术可以减少网络操作和服务交付延迟，以改善用户的QoE（体验质量）。在MEC环境中，本文构建了一个模拟平台，用于多 - 二匹比视频缓存和调度方案VECSIM（视频边缘CloudSim）。 VECSIM提供了一个特定的仿真环境，可在移动边缘计算方案中进行协作和调度策略验证多峰视频缓存。与简单的数值模拟和复杂的现实部署不同，VecSim提供了一个简单的接口，用户可以调用，此外，它可用于提供更大的，更灵活的请求场景，这些场景更接近实际环境。基于Edge Computing Simulation平台EdgeCloudsim，该平台添加并修改了许多功能，因此可以在多贵族视频缓存和调度方案中有效使用，该场景现在包括七个主要模块：服务器管理模块，网络模块，用户用户，用户移动模块，任务加载器发电机模块，视频存储模块，边缘客户管理模块和边缘编排模块。借助此平台，研究人员可以轻松，快速验证其视频缓存和调度策略。
The development of the mobile Internet has led to a shape increase in video traffic data. New Mobile Edge Computing (MEC) technology can reduce network operation and service delivery delays, so as to improving the QoE (Quality of Experience) of user. In MEC environment, this article builds a simulation platform for multi-bitrate video caching and scheduling scenarios VECSim (Video Edge CloudSim). VECSim provides a simulation environment specific to verify multi-bitrate video caching collaboratively and scheduling strategy in the Mobile Edge Computing scenarios. Unlike simple numerical simulations and complex real-world deployments, VECSim provides a simple interface that can be called by the user, besides, it can be used to provide larger-scale, more flexible request scenarios which are closer to the actual environment. Based on the edge computing simulation platform EdgeCloudSim, this platform adds and modifies quite a few functions so that it can be effectively used in multi-bitrate video caching and scheduling scenarios, which now includes seven main modules: Server Management Modules, Network Module, User Mobility Module, Task Loader Generator Module, Video Storage Module, Edge Client Management Module, and Edge Orchestrator Module. With this platform, researchers can easily and quickly verify their video caching and scheduling strategies.
