IP datagram embodies the mechanism of Internet protocol in IP layer.
IP数据报的内容体现了网际互联层的网间协议的协议机制。
Plain IP packet, or IP datagram: IP packets are used to encapsulate any of the following protocols.
普通IP包或IP数据报：IP包可用来封装以下任何协议。
The paper chiefly introduces a cryptographic solution about key recovery and key recovery capability by adding key recovery information to an IP datagram.
该文主要介绍了关于密钥恢复的一种加密解决方案和一种通过在IP数据报加入密钥恢复信息提供密钥恢复能力的密钥恢复的方式。
On the other hand, because of the ability to forward IP datagram at high speed, more and more layer3 switches have been participating in the construction of networks.
另一方面，三层交换机由于其对IP数据报的高速转发能力，也越来越多地参与到网络拓扑的建设当中。
The addresses, encapsulated as source and destination in the IP datagrams header, are used to transmit the datagram to their destination, called routing. Basically, this creates two scenarios
地址（在IP数据报头中封装为源和目的地地址）用来将数据报传输到其目的地，这个过程称为路由。
Internet Protocol (IP) provides a host-to-host packet — or datagram — delivery service.
网际协议(IP)提供“主机对主机”包(或数据报)传递服务。
IP provides the most basic form of datagram delivery across the boundaries of the underlying physical networks.
IP在底层物理网络的边界之间提供最基本的数据报传递形式。
If the gateway processing a datagram determines that the time to live field in the datagram's IP header is 0, it discards the datagram and notifies the sending host with a time Exceeded Message.
如果处理数据报的网关测定该数据报i p头中的生存时间字段为0，则丢弃该数据报并用超时消息通知源主机。
The problem with that is that if a fragment never arrives, there is nothing at the IP level that will cause a retransmit, so the entire datagram is lost.
的问题是，如果一个片段从未到达，没有IP水平将导致一个中继，所以整个数据报丢失。
User Datagram protocol (UDP) is a protocol for sending data on an IP-network.
用户数据报协议(udp)是一个ip网络协议发送数据。
For traditional IP network, the currently deployed routing scheme is focused on constructing end-to-end connectivity which usually supports only one type of datagram service.
对于传统的IP网络，目前实施的路由策略集中于建立端到端的连接，并且一般只考虑一种服务数据结构。
The IP layer at the receiving host must accumulate these fragments to completely reconstitute the original datagram.
目的主机的IP层将接收到的所有分片重装成一个完整的数据报。
The IP layer at the receiving host must accumulate these fragments to completely reconstitute the original datagram.
目的主机的IP层将接收到的所有分片重装成一个完整的数据报。
