I've also found that having a layer of indirection between the JMS client and the actual JMS destination gives the architecture additional flexibility.
我还发现在JMS客户机与实际的jms目的地之间设置一个间接层可以增加体系结构的灵活性。
Transport Layer protocols, such as the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), specify a source and destination port number in their packet headers.
传输层协议，诸如传输控制协议（TCP），用户数据报协议（UDP）， 会在它们的头部指定一个资源和目的地的端口号。
The network layer manages the movement of packets in a network, specifically making sure packets get to their destination (also called routing).
网络层（networklayer） 负责管理网络中的报文移动，具体来说就是确保报文都到达自己的目标（也称为路由）。
Layer 3 source and destination addresses do not change when the packet traverse.
当储存器横过的时候，层3个来源和目的地住址不改变。
Packet by Packet Layer 3 switching technology inspectoscope every Packet, intransit to destination.
报文到报文的第三层交换技术检查每一个报文并将报文转发到其目的地。
Although a destination host may have a message buffer, the buffer may become full before new packets can be read by a higher-layer application.
虽然目的地主机可能有消息缓冲区，缓冲区之前可能成为完整的新的数据包可以读一个更高级别的应用程序。
Although a destination host may have a message buffer, the buffer may become full before new packets can be read by a higher-layer application.
虽然目的地主机可能有消息缓冲区，缓冲区之前可能成为完整的新的数据包可以读一个更高级别的应用程序。
