The trend toward fewer users per segment is known as microsegmentation. Micro-segmentation allows the creation of private or dedicated segments—that is, one user per segment. Each user receives instant access to the full bandwidth and does not have to contend for available bandwidth with other users. As a result, collisions (a normal phenomenon in shared-medium networks employing hubs) do not occur, as long as the equipment operates in full-duplex mode. A LAN switch forwards frames based on either the frame's Layer 2 address (Layer 2 LAN switch) or, in some cases, the frame's Layer 3 address (multilayer LAN switch). A LAN switch is also called a frame switch because it forwards Layer 2 frames, whereas an ATM switch forwards cells.
參考答案:少的趋势,每部分用户称为microsegmentation. 微型分割允许开设私人或专用部分,即每一个用户部分. 每个用户接收即时获得充分带宽以及没有争夺可用带宽,与其他使用者. 由于碰撞(正常的现象,在共享介质网络的枢纽和聘用)不发生 只要设备运转全双工模式. 前锋局域网交换机采用基于帧帧的2层地址(局域网交换机2层),或 在有些情况下,帧的第三层地址(多层局域网交换机). 局域网交换机也称为帧帧2层交换机因为前锋, 而一个ATM交换机前锋细胞.
