Abstract: Along with the development of the next-generation intemet technology,and the fact that CERNET2 is gradually applied to practice in E-learning,the high-bandwidth, high-speed,and high-dependability network will create more opportunity and possibility in terms of providing more excellent educational service for E-learning.In the near future,the multimedia courseware which includes lots of large-particle information object such as video, audio and so on,will applies to practice in E-learning extensively.What's more,it will have a great promotion in the Qos of E-learning.
