Next Expected Packet Number 下一个期望包编号
But if the packet doesn't match a rule, then it is compared to the next rule in the chain.
但是,如果信息包与这条规则不匹配,那么它将与链中的下一条规则进行比较。
It alighted on the roof of the villa next to theirs and began extracting the cigarettes from the packet.
它在一间别墅的房顶上落下,点起一根,开始把香烟抽出来更多。
If the route table lookup shows that the packet is destined for a non-local subnet, the router forwards the packet to the next-hop router using the next-hop router's MAC address.
如果查找路由表显示包的目的地不在本地子网,路由器就利用下一跳路由器的MAC地址把包转发给下一跳路由器。
