网关

This paper presents a set of performance metrics, which can describe performance characteristics of a transition gateway, including bi-directional latency, commix latency and weighed commix latency.

本文在通用网络设备测试标准的基础上[1，2]，结合转换网关的特点，创新性地提出了一套转换网关性能测试指标。

The path of least resistance is to get an e-mail security gateway, which is analogous to a firewall for e-mail.every message going in or out pases through the gateway,allowing security policies to be enforced (where and when messages can be sent),virus checking to be performed,and messages to be signed and encryp ted.

阻力最小的道路就是采用电子邮件安全网关，它相当于电子邮件的防火墙。进出的每一条信息都要经过网关，网关可以实施安全政策(信息在何时向何地发送)、执行病毒检查并给信息签名和加密。

In the end,we make an analysis to the gateway,carry out it and have a test.

最后，我们对NAT/PT网关进行了分析，实现了转换网关并进行了测试。

Ethernet gateway refers to the GNE which communicates with the NM system directly via Ethernet interface.

以太网关指通过以太网口和网管系统直接通讯的网关网元。

The key technique of this design scheme was to use SOPC technique based on Nios II to construct the hardware and software system of home gateway. Considering the programmable feature of FPGA and the portable feature of IP core, the design scheme solved effectively the incompatibility and importable disadvantage of conventional embedded home gateway.

该方案以基于NiosⅡ的SOPC技术为核心，构建家庭网关的软硬件系统，充分发挥了FPGA的可编程特性和IP核的易移植等特点，有效弥补了传统嵌入式网关的兼容性差、不易移植的缺陷，对家庭网关的设计与开发作了有益的探讨。

There are two categories of dynamic routing protocols, Interior Gateway Protocol and Exterior Gateway Protocol. Interior routing occurs within an autonomous system.

内部网关协议是用于各个自治系统内部的选路协议集合，包括RIP和OSPF在内的常见动态路由协议都属于内部网关协议。

ChangeGateway provide replacement source gateway settings, the need for manual input to change the gateway and the gateway to be changed.

详细说明： ChangeGateway提供的是更换网关设置的源码，需要手工输入要换的网关和要改的网关。

This paper sententiously introduces features of IA , family gateway and the functional distribution between them, describes the common design method of simulating family gateway by using SX52, and especially discusses how to extend hardware and soft-ware on SX52 to simulate functions of family gateway and IA .

本文简要介绍了信息家电和家庭网关的特点以及它们的功能分配问题，描述了利用SX52单片机模拟家庭网关的通用设计方法，具体对如何在SX52上扩展软硬件模拟家庭网关功能和信息家电功能进行了重点分析讨论，并以模拟电冰箱为例做了具体实现，为后续的家庭网关和信息家电研究提供了基础实验平台。

New technology has made it possible that a normal telephone subscriber who signed with IP telephony provider,can dial in a gateway which converts the voice signals into packets.The packets will be transported over IP network and will be converted back to voice signals through the gateway on the other end.The called party can receive the call from a PSTN phone whatever signed with IP telephony provider or not.

新技术已经使其成为可能，即一个向IP电话服务商登记的普通电话用户可以拨通一个网关，该网关使语音信号转化为信息包，信息包将通过IP网络转输并通过另一端的网关转回语音信号，被叫方可以从一台无论是否向IP电话服务商登记的PSTN电话收到呼叫。

This is done by introducing shared intermediate connection concentrators called gateways.

这是通过引入称为网关(网关1－网关L)的共享中间连接集线器实现的。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
