. When two local area networks are to be connected, a computer called a bridge is inserted between them, connected to both. Each packet transmitted on either network causes an interrupt on the bridge, to let the bridge see if the packet has to be forwarded. Suppose that it takes 250 µsec per packet to handle the interrupt and inspect the packet, but forwarding it, if need be, is done by DMA hardware without burdening the CPU. If all packets are 1 KB, what is the maximum data rate on each of the networks that can be tolerated without having the bridge lose packets?
