论网络互连

On Network Interconnection

网络互连是由重发器、网桥、路由器和网关的恰当使用和适当组合而实现的．这些中继设备具有不同的性能，因此，重要的是要选择最合适的互连设备．重发器互连类似的局域网段，形成单一扩展的局域网；网桥互连类似的LAN，形成单一的子网络；路由器互连子网络，形成单一网络，网关互连不同的网络，形成集成网络．

Network interconnection is provided by the appropriate combination and use of repeaters, bridges, routers and gateways. Each of these relays has different capabilities and so it is important to choose the one best suited to the task.Repeaters interconnect similar LAN segment to form a single extended LAN, bridges interconnect similar LANs to form a single subnetwork, routers interconnect subnetworks to form a single network, gateways interconnect different networks to form an integrated network.
