The node can receive standard Ethernet packet and output corresponding current loop.
此节点可以接收标准以太网报文，转换成相应的电流输出。
Since we are looking for IP packets, we can check for IP packets by looking at the Ethernet packet type.
因为我们寻找的是IP数据包，所以我们能通过检查Ethernet数据包类型来检查 IP 数据包。
So in this example, we first need to extract the Ethernet packet, including the data payload, from the raw network packet.
所以在本例中，我们首先需要从原始网络数据包中提取Ethernet数据包，包括数据有效负载。
Ethernet packet headers, including the Ethernet source and destination address, packet size and the Ethernet packet type.
Ethernet数据包头，包括Ethernet来源和目标地址，数据包大小和Ethernet数据包类型。
The output here specifies that the Ethernet packet contains IP data, specifies the overall packet size and time, and the destination and source Ethernet addresses for the packet.
这里的输出表明 Ethernet数据包包含了IP数据、全部数据包大小和时间，以及数据包的目标和来源地址。
In this case, you can see the raw Ethernet, IP, and TCP packet data, including the source and destination host information and packet options.
在这个示例中，您可以看到原始以太网、IP和TCP数据包，包括源、目标主机的信息以及数据包选项。
This means that routers strip off the Ethernet header upon reception of a packet, and then add a new lower layer header-ethernet or otherwise-when the packet is forwarded.
这意味着路由器在收到数据封包时就会去除以太网的数据头信息，加上低一层的数据头信息(以太网层或者其他层的)，然后发送给下一方。
This is an Ethernet term used to describe a network scenario wherein one particular device sends a packet on a network segment, forcing every other device on that same segment to pay attention to it.
这是一个以太网术语，用来描述这样的网络情景，即网段上某个特定设备发送出一个数据包，迫使同网段上其他的设备就必须注意到这一点。
This paper introduces the characters of resilient packet ring (RPR) technologies, and the advantages of RPR comparing to SDH/SONET and Ethernet when provides data services in ring topology.
介绍了弹性分组环（RPR）技术的特征，将其与SDH/SONET、以太网技术作了对比，以体现其在环型拓扑结构上支持数据业务的优势。
Taking a case study approach to several deployment scenarios, the primary focus is on how ATM, Ethernet, and Frame Relay edge services can be deployed over packet-switched networks.
通过案例研究讲解集中部署方案，重点介绍ATM、以太网和帧中继边缘服务如何能够部署在分组交换网络中。
What companies need is a metropolitan Ethernet architecture with the resiliency of SONET but with significant network efficiencies for packet-based services.
公司所需要的是城域以太网的架构加上上SONET的弹性，但要具有适合基于分组服务的网络高效率。
