data link layer

基本解释

Discovery algorithms usually go from high layer (IP layer) to low layer (data-link layer).
拓扑发现算法的发现通常是从IP层到链路层。
The key technology of net-charging based on data-link Layer is the capture and analysis of data frame.
基于数据链路层的网络计费方式中关键的技术在于链路层数据包的捕获及分析。
We add the function of the per interface label space based on the source code, which enables to extend the LDP implementation to systems in which the data-link layer is ATM or FR.
我们在原实现基础上添加了每端口标记空间功能，使LDP实现可以向数据链路层为ATM或者帧中继的系统扩展。
