1.A macroscopic method to establish the relationship between the relative trip comfort coefficients of all traffic modes and different distances is advanced, and some key steps are explained in detail.
2.It takes several influencing parameters into account, including encryption/decryption and digital signature methods, key length, maximum segment size, round trip time, initial value of time-out sequence, the number of packets per ACK, maximum congestion control window size and packet loss rate.
