德國HIRSCHMANN赫斯曼交換機(jī)技術(shù)參數(shù)
Hirschmann Industrial Group Co., Ltd. as an expert in automation networks, 1984 at the University of Stuttgart in Germany built the world's first fiber-optic Ethernet, 1990, and the first in the world to launch a redundant Ethernet ring (HIPER -Ring). Hirschmann offers a complete and comprehensive for industrial and office environments of data communications systems, products ranging from Gigabit Ethernet, Fast Ethernet and Ethernet products to fieldbus systems, as well as actuators and sensors used the ASI connector, these products are widely, the main range of applications including office communications, manufacturing automation, process control, traffic control, as well as independent machine control system.

德國HIRSCHMANN赫斯曼交換機(jī)技術(shù)參數(shù)

德國HIRSCHMANN赫斯曼交換機(jī)的背板帶寬，是交換機(jī)接口處理器或接口卡和數(shù)據(jù)總線間所能吞吐的zui大數(shù)據(jù)量。背板帶寬標(biāo)志了交換機(jī)總的數(shù)據(jù)交換能力，單位為Gbps，也叫交換帶寬，一般的德國HIRSCHMANN赫斯曼交換機(jī)的背板帶寬從幾Gbps到上百Gbps不等。一臺交換機(jī)的背板帶寬越高，所能處理數(shù)據(jù)的能力就越強(qiáng)，但同時設(shè)計成本也會越高。 一般來講，計算方法如下: 
1）線速的背板帶寬 
考察交換機(jī)上所有端口能提供的總帶寬。計算公式為端口數(shù)*相應(yīng)端口速率*2（全雙工模式）如果總帶寬≤標(biāo)稱背板帶寬，那么在背板帶寬上是線速的。 
2）第二層包轉(zhuǎn)發(fā)線速 
第二層包轉(zhuǎn)發(fā)率=千兆端口數(shù)量×1.488Mpps 百兆端口數(shù)量*0.1488Mpps 其余類型端口數(shù)*相應(yīng)計算方法，如果這個速率能≤標(biāo)稱二層包轉(zhuǎn)發(fā)速率，那么交換機(jī)在做第二層交換的時候可以做到線速。 
3）第三層包轉(zhuǎn)發(fā)線速 
第三層包轉(zhuǎn)發(fā)率=千兆端口數(shù)量×1.488Mpps 百兆端口數(shù)量*0.1488Mpps 其余類型端口數(shù)*相應(yīng)計算方法，如果這個速率能≤標(biāo)稱三層包轉(zhuǎn)發(fā)速率，那么交換機(jī)在做第三層交換的時候可以做到線速。
