交換式結(jié)構(gòu)： 在交換式以太網(wǎng)中，交換機根據(jù)收到的數(shù)據(jù)幀中的MAC地址決定數(shù)據(jù)幀 應(yīng)發(fā)向交換機的哪個端口。因為端口間的幀傳輸彼此屏蔽，因此節(jié)點就 不擔(dān)心自己發(fā)送的幀在通過交換機時是否會與其他節(jié)點發(fā)送的幀產(chǎn)生沖 突。 為什么要用交換式網(wǎng)絡(luò)替代共享式網(wǎng)絡(luò)： ·減少沖突：交換機將沖突隔絕在每一個端口（每個端口都是一個沖突 域），避免了沖突的擴散。 ·提升帶寬：接入交換機的每個節(jié)點都可以使用全部的帶寬，而不是各 個節(jié)點共享帶寬。
