基于Bloom Filter的云内容路由优化

Abstract

Abstract:

With the rapid advances on Tri-networks integration in China,the traditional broadcasting content service mode can no longer meet the increasing requirements on interactive content service mode.The key to this problem is an elastic and efficient cloud-based media network by leveraging cloud computing technology.This solution has been considered as the key of the Next Generation Broadcasting Network (NGB).One of the critical design objectives is to further improve the mean response time in this cloud-based media network.This paper proposes the use of a global Bloom Filter to improve the content routing schemes.Specifically,we design two improved routing schemes (i.e.,parallel scheme and cut-through scheme) after introducing Bloom Filter,to reduce the mean response time.We formulate both the traditional and the proposed routing schemes as queuing models,and simulate them by using OMNeT++.The analytical results agree well with the numerical ones.The results show the proposed schemes can save up to 65.2% mean response time in different networking scenarios.
