Abstract:For the purpose of sharing resources of courses,funded by Integration Project for National Excellent Courses,we developed a platform for sharing excellent courses.Currently,the service nodes of platform are distributed in 5 important cities of east,central and west of China.And more than one thousand excellent courses from colleges of 31 provinces have been collected and shared.The platform is consisted of data management and P2P video on demand system.Data management employs federation mechanism and each member in the federation updates data dynamically so as to keep data consistent with other members.P2P video on demand system introduces a hybrid architecture so that it can monitor the entry and exit of nodes and do Load Balance Scheduling.Now,the platform runs online.
Keywords:excellent course  resource sharing  data management  video on demand
