Therefore , the project is not only academically valuable but also practically useful . in the course of studying and designing the concentrator , we firstly analyzed its function , defined its function module and also selected ethernet switch to implement switch module 在对集中器的研究设计中,首先分析了集中器的功能组成,划分其功能模块,并对其中的交换机的选择进行了方案比较分析,最终确定了对以太网交换机选择。
The market facing " the second layer ethernet " is the biggest switch market at present . to study and develop a gigabit ethernet switch is task of the research , which has independent intellectual property right and high commercialization degree . the switch is ripe and reliable 本研究课题的任务是研究开发出具有自主知识产权、成熟可靠、商用化程度高的千兆以太网交换机,提供二层交换,带有网络管理功能,主要作为zan ( zoneaccessnetwork )交换机(或称为中心接入交换机)使用。
With the high - speed development of network and the enlargement of the demand of network ' s application , it is the ethernet switcher that developed from the tcp / ip network becomes the indispensable communication device , and distributed ethernet switcher especially works as the central routing device on the core network or backbone network for its high - capacity , high - performance and expansibility 随着计算机网络的飞速发展,网络应用需求量不断的扩大,基于tcp ip网络发展起来的以太网交换机成为不可缺少的通信设备,而分布式以太网交换机更是以其高容量、高性能、可扩展性的强大优势成为核心网、骨干网上交换路由的主要设备。
Itu telecom world 2003 - geneva , switzerland - october 13 , 2003 - znyx networks , the leading provider of embedded high - availability ethernet for carrierclass systems , today introduced the zx5000 - the world s first commercially available gigabit ethernet switch based on advancedtca atca , a new industry standard architecture for telecommunications Znyx发布业界第一款atca以太网交换单板2003 - 11 - 20 ,嵌入式高可用以太网产品厂商znyx网络公司今天宣布推出zx5000 -业界第一款商用的基于advancedtca ? atca规范的千兆以太网交换单板。
In the first quarter from 2001 to 2002 , chinese switch market has been keeping higher growth rate all the time and increment is up to about 3 million ( the port is counted ) each season . fast switch becomes market mainstream . sales volume of gigabit ethernet switch rises rapidly 从2001年到2002年第一季度,中国交换机市场一直保持较高的增长速度,每季增量都达300万(端口数)左右; 10 100兆交换机为市场主流,千兆以太网交换机销量迅速上升,目前面向“第二层以太网”的市场是最大的交换机市场。
