My primary task was to build a state-of-the-art network infrastructure that would support a leading graduate research center in the transportation field. 在那里,我首要的任务是去建一个文学园地的网络基础设施,以便支持传输领域中领先的研究生研究中心。
The idea of application-level multicast service is that all multicast functions are implemented in end hosts instead of routers. The primary advantage is that IP network architecture need not to be changed, support of lower level network is not required and the deployment is simple. 应用层组播服务的思想是由端系统而不是路由器实现组播通信的所有功能,其最大的优势在无须改变现有的IP网络结构,不需要底层网络的支持并且部署简单。
