摘要
电信网、计算机网及有线电视网的业务与市场已经开始渗透与融合 ,在其发展过程中 ,IP和ATM是当然的主角。随着基于IP的应用及IPoverSDH ,IPoverDWDM等宽带IP技术的迅速发展 ,ATM正面临IP技术的全面挑战。但与此同时 ,IP与ATM技术的结合也是当今网络技术发展的趋势 ,其融合体现在路由技术、IP交换与ATM交换技术集成以及利用ATM交换技术直接实现IP数据包的交换等方面。在相当长的时间内 ,ATM和IP各有其发展领域 。
IP and ATM are the core technologies of existing communication networks.In this paper, their developing trends of competition and cooperation are indicated. This paper first discusses the difference of ideas, targets, techniques and the market competition between IP and ATM. Then IP over ATM, the cooperative result of IP technology and ATM technology is introduced, emphasizes to the motivity and model between IP and ATM, so does the basic principle, development and application of IP over ATM. Finally, prospect of IP and ATM are presented.
