we talk about the length of a connection chain containing multiple connections, we use the RTT between a request and its response to represent the length of the connection chain, why not use the RTT between a request packet and its acknowledgement?  Question options: Each acknowledgement is from the sender's adjacent directly connected host, other than the end host of the chain.     Not really, the RTT between a request and its acknowledgement can also represent the length of the whole connection chain.     response contains the request processing time.     acknowledgement does not contain the request processing time.
