【摘要】 路径循环问题是影响多协议标签交换(MPLS)网络质量的主要因素之一,但是目前基于异步传输模式(ATM)的MPLS却缺乏有效的环路检测措施。文章首先介绍了MPLS中解决环路问题的各种方法,然后结合MPLS兼容ATM的信元特点,提出了一种利用ATM适配层中的AAL5数据单元对分组在转发过程中进行环路检测的方法。更多还原

【Abstract】 Routing loop is one of the most crucial problems that can affect the capability of the MPLS network, but there hasn’t an effect method to detect the loop at the ATM-based MPLS network. This paper introduces some loop solving methods in MPLS firstly, then, according to the characteristics of cells in ATM-based MPLS, promotes a method to detect the loop using the AAL5 cell in ATM.更多还原
