Linux虚拟网卡-阿里云

编写一个Linux虚拟网卡来实现类NVI

我们可以在Linux上使用loopback接口来模拟两个阶段的路由抉择，第一个阶段是走一遍PRE/POST ROUTING流程，将NAT实施完毕，第二阶段完成单纯路由转发。然而需要在Netfilter上挂钩子，以便取消关联在skb上的路由项，并且取消关联在skb上的conntrack信息，因为在第二...

Linux下使用虚拟网卡的ingress流控(入口流控)

Linux内核实现了数据包的队列机制，配合多种不同的排队策略，可以实现完美的流量控制和流量整形(以下统称流控)。流控可以在两个地方实现，分别为egress和ingress，egress是在数据包发出前的动作触发点，而ingress是在数据包接收后的动作触发点。Linux的流控在这两个位置实现的并不对...

Linux驱动之虚拟网卡

写网卡驱动之前我总结一下个人的一些观点：其实写驱动并不是大家想想的那么难，这里我客观评价一下内核层和应用层的区别：底层：工作在内核层的朋友应该有这种感觉，才开始学的时候真的很难，也就是说上手难，我就拿Linux驱动来说吧，写一个完整的驱动，你得装一个虚拟机跑Linux吧，用来编译驱动程序，虚拟机...
