Each line is prefixed with the protocol level within the packet that was scanned.
对于所扫描的数据包内的所有行，使用协议级别作为前缀。
When you examine the raw data, snoop automatically formats and parses the content of the packet for you, even down to the individual protocol level.
当您查看原始数据的时候，snoop可以自动地为您格式化并解析数据包的内容，甚至深入到每个协议级别。
Now let's see at a high level how a network packet is structured. Depending on the protocol being used for the communication, you could be dealing with one of the following IP packets.
现在我们从更高的层次看看网络包的结构是怎样的。
We designed and implemented a simplified link-level protocol with elastic buffered flow-control and buffered wormhole routing switching, it can support to transmit variable-length packet.
提出了一种采用伸缩缓冲流量控制方法、缓冲虫洞路由交换机制、支持可变长度数据包传输的链路控制协议。
Since the UDP protocol is non-connection, a transfer control should be taken on the high level to avoid high packet loss when the network is bad.
而UDP协议是无连接的，因此要在上层对用户数据报协议包的发送速率进行控制，来避免在网络情况不良的时候，产生较大的丢包率。
According to this problem, in this paper, a new reliable multicast protocol is proposed which integrates packet-level FEC and rate-adaptive technology on the basis of unidirectional satellite link.
针对这一问题，在单向链路卫星组播结构基础上，融合分组级FEC和自适应速率技术，提出了一种新的可靠组播协议，经过理论分析可知，新的协议具有较好的差错控制和拥塞控制能力。
This time at least 5 seconds for OSPF routing protocol, during the fault the packet will be dropped, most of the applications can accept this level of delay.
对OSPF路由协议，这个时间至少为5秒，期间经过故障节点或链路的流量将会被丢弃，绝大多数的应用可以承受这种程度的延迟。
