然而,快速以太網(wǎng)與交換式以太網(wǎng)技術(shù)的發(fā)展,給解決以太網(wǎng)的非確定性問題帶來了新的契機,使這一應(yīng)用成為可能。首先,EtherNet的通信速率從10M、100M增大到如今的1000M、10G,在數(shù)據(jù)吞吐量相同的情況下,通信速率的提高意味著網(wǎng)絡(luò)負(fù)荷的減輕和網(wǎng)絡(luò)傳輸***的減小,即網(wǎng)絡(luò)碰撞機率大大下降。其次,采用星型網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu),交換機將網(wǎng)絡(luò)劃分為若干個網(wǎng)段。EtherNet交換機由于具有數(shù)據(jù)存儲、轉(zhuǎn)發(fā)的功能,使各端口之間輸入和輸出的數(shù)據(jù)幀能夠得到緩沖,不再發(fā)生碰撞;同時交換機還可對網(wǎng)絡(luò)上傳輸?shù)臄?shù)據(jù)進行過濾,使每個網(wǎng)段內(nèi)節(jié)點間數(shù)據(jù)的傳輸只限在本地網(wǎng)段內(nèi)進行,而不需經(jīng)過主干網(wǎng),也不占用其它網(wǎng)段的帶寬,從而降低了所有網(wǎng)段和主干網(wǎng)的網(wǎng)絡(luò)負(fù)荷。再次,全雙工通信又使得端口間兩對雙絞線(或兩根光纖)上分別同時接收和發(fā)送報文幀,也不會發(fā)生沖突。因此,采用交換式集線器和全雙工通信,可使網(wǎng)絡(luò)上的沖突域不復(fù)存在(全雙工通信),或碰撞機率大大降低(半雙工),因此使EtherNet通信確定性和實時性大大提高。
