Consider a commercial cable-Ethernet network, with the link rate 10 Mbps. Suppose that the propagation delay between the end nodes is always 25.6 s, and that there are many pairs of nodes are communicating.

Find the approximate Ethernet efficiency (i.e., the fraction of time for transmission, discussed in class) for transmitting 512 byte packets. Find the threshold of the packet size such that the cable-Ethernet is more efficient than the Aloha network with the slotted-time system if the packet size is larger than this threshold.

Consider a commercial cable-Ethernet network, with the link rate 10 Mbps. Suppose that the propagation delay between the end nodes is always 25.6 us, and that there are many pairs of nodes are communicating. Find the approximate Ethernet efficiency (i.e., the fraction of time for transmission, discussed in class) for transmitting 512 byte packets. Find the threshold of the packet size such that the cable-Ethernet is more efficient than the Aloha network with the slotted-time system if the packet size is larger than this threshold
