Target (Servlet and MBean) : Provides inbound listener services for transport and document protocols from internal and external endpoints as well as transport-level security functions.
如Meeraj之前所说，SCA还提供了协议抽象，这样在远程调用时代码就无需处理低级的传输层api。
As Meeraj mentioned previously, SCA also provides protocol abstraction so that code does not need to deal with low-level transport APIs when making remote calls.
SIP协议支持TLS、UDP及TCP作为传输层，因此唯一可行的方案就是采用Grizzly框架。
The SIP protocol support TLS, UDP and TCP as transport, so they only viable solution was to use the framework.
TCP/UDP –传输层协议
结果，名为TCP/IP的一套网络互联协议（在首批标准化的两个协议——即传输控制层协议和互联网协议后）产生。
The result was a suite of internetworking protocols known as TCP/IP (after the first two protocols defined by the standard, Transmission Control Protocol and Internet Protocol).
所有应用层协议都使用套接字层作为与传输层协议之间的接口。
All application layer protocols use the sockets layer as their interface to the transport layer protocol.
用户认证协议：该协议从服务器到客户端进行身份验证，且通过传输层运行。
User Authentication protocol: This protocol authenticates the client to the server and runs over the transport layer.
网络加密在选定协议的网络传输层上进行。
Network encryption occurs at the network transfer layer of a selected protocol.
每个层都使用下面一层的服务，这使得顶层协议能够在物理网络上传输消息。
Each layer employs the services of the layer underneath, which enables a top layer protocol to transmit messages over the physical network.
反过来，ip层又提供由网际控制报文协议(ICMP)和传输控制协议(TCP)使用的服务。
The IP layer, in turn, provides services used by the Internet Control Message Protocol (ICMP) and Transmission Control Protocol (TCP).
流控制传输协议(SCTP)是2.6内核中增加的一个新的传输层协议。
Stream Control Transmission protocol (SCTP) is a new transport layer protocol added to the 2.6 kernel.
在传输层，数据使用TLS协议进行加密和封装，然后通过网络进行传输。
At the transport layer, the data is encrypted and wrapped in the TLS protocol, for transport across the network.
OBEX协议层是在RFCOMM 层上面实现的，如果想把数据以对象（例如文件）的形式传输，那么 OBEX很有用。
The OBEX protocol layer is implemented above the RFCOMM layer and is useful when you want to transfer data as an object, such as files.
架构：针对消息格式、消息交换模式(mep)、底层传输协议绑定、消息处理模型以及协议可扩展性的几个规范层。
Architecture: Several layers of specifications for message format, message exchange patterns (MEP), underlying transport protocol bindings, message processing models, and protocol extensibility.
称为物理层协议的两个底层处理网络电缆上的实际信号传输。
The two bottom layers, called the physical layer protocols, take care of the actual signal transfer over the network cable.
传输层协议：该协议提供服务器身份验证、隐私和具有完美转发隐私的完整性。
Transport Layer protocol: This protocol accommodates server authentication, privacy, and integrity with perfect forward privacy.
SSL在传输层上工作，不了解HTTP或SOAP协议。
SSL works at the transport level, and does not understand the HTTP or SOAP protocols.
两种最流行的传输层协议是传输控制协议（TCP）和用户数据报协议（UDP）
The two most popular transport layer protocols are the transmission control protocol (TCP) and the user datagram protocol (UDP)
因为您可以用WS - Routing描述一条完整的消息路径，所以SOAP消息不需要到传输层协议(如HTTP)的绑定来描述消息路径。
Because you can describe an entire message path with WS-Routing, a SOAP message does not require a binding to a transport-layer protocol (like HTTP) for describing the message path.
因为您将使用HTTP作为传输协议，所以将在Web层上工作。
Because you'll be using HTTP as the transport protocol, you will be working on the Web tier.
回想一下，InternetProtocol (IP)是传输协议(通常称为传输控制协议或TCP)下面的核心网络层协议。
Recall that the Internet protocol (IP) is the core network layer protocol that sits below the transport protocol (most commonly the Transmission Control protocol, or TCP).
Linux也可以支持诸如流控制传输协议(SCTP)之类的协议，它提供了很多比tcp更高级的特性(是传输层协议的接替者)。
Linux also supports protocols such as the Stream Control Transmission protocol (SCTP), which provides many advanced features above TCP (as a replacement transport level protocol).
