Suppose you have a desktop computer with both a wired Ethernet connection and a Wi-Fi connection. (a) What benefits would accrue from using Multipath TCP (MPTCP) in this situation? (b) Suppose a particular TCP packet was sent over the Wi-Fi channel/path but could not be acknowledged because that channel/path became inactive after the packet was sent. What would need to be done to re-send the packet over the Ethernet channel/path? In other words, could the Wi-Fi frame just be re-sent over the Ethernet channel/path? (c) Given that the payload of Wi-Fi frames can be larger than the payload of Ethernet frames (i.e., that the maximum transmission unit (MTU) for Wi-Fi is larger than the MTU for Ethernet), what problem could arise in the situation described in the previous question and how might it be avoided?
