摘　　要：为从根本上解决远程教育系统中因时间、空间和人员等因素所造成无法进行异地教务会议问题,在研究JXTA(Juxtapose)技术的基础上,提出将JXTA应用于远程教务会议中。通过研究JXTA平台路由机制,发现JXTA应用于远程教务会议中,虽然能满足远程教务会议需求,但存在路由不稳定、不可靠等问题。因此引入一致性哈希算法Chord环,以覆盖JXTA路由,解决远程教务会议中路由问题,提高远程教务会议网络稳定性和可靠性,使远程教育体系更加完善。To change impossibility of live teaching affairs meeting at different places, the JXTA （Juxtapose） is applied in distance teaching affairs meeting for the first time. Study to routing mechanism of JXTA platform shows that JXTA is able to meet the needs of distance teaching affairs meeting but the routing is unstable and unreliable. So, a scheme introduced consistency hash algorithm Chord ring to cover JXTA routing is proposed to solve the problem. The seheme also solves technical and routing problems in distance teaching affairs meeting, providing stability and reliability of the network in reality and makes distance education system more perfect.
