网络接口层

基于TCP/IP的分层模型，介绍了代理技术在Internet的应用层、网间网层、网络接口层上的实现，并重点以具体事例对网络接口层的代理技术的实现进行了分析。

The paper presents the realization of Internet proxy technology in the application layer , TCP layer , IP layer and network interface layer of Internet based on TCP / IP hierarchical model , and exemplifies concretely the realization of the proxy technology in network interface layer .

模型的底层是网络接口层。

At the base of the model is the network interface layer .

融合后的双协议栈拥有共同的API层、TCP层以及网络接口层，而在网络层则存在有两套不同的协议。

The integrated stack processes the common API layer , TCP layer and Interface Abstraction layer , but has two different network layers .

基于ISDN的PPP协议网络接口层的设计与实现

Implementation of PPP Network Interface over ISDN

当网络接口层从它的上一层收到一个数据包时，它就加上一个前同步信号以及循环冗余校验（CRC）。

When the network interface receives a packet from the layer above , it adds a preamble and CRC .

TCP/IP协议可以用一个分成四个层次的模型来描述：网络接口层、互联网层、传输层和应用层。

TCP / IP protocols map to a four layer model : Network Interface , Internet , Transport , and Application .

如果这一帧的硬件地址是广播地址，或者它与本机网络接口层相匹配，此帧就通过这一层送到上一层中适当的协议程序。

If the hardware address in the frame is a broadcast address , or if it matches the network interface , the frame is passed to the appropriate protocol in the layer above .

并利用Linux网络接口低层数据结构（netdevice{}）和监测模块中的结果，衡量网络接口的负载情况，进而调整路由选路表。

Utilize Linux network interface lower data structure ( net_device { } ) and the monitor result , scale load situation of the network interface then adjust the route table .
