The following text says this which I'm not able to quite agree :

client C sends a request R to server S. The time taken by a communication link to transport R over the link is D. P is the maximum time needed by S to recieve , process and reply to R. If omission failure is assumed ; then if no reply to R is received within 2(D+P) , then C will never recieve a reply to R .

Why is the time here 2(D+P). As I understand shouldn't it be 2D+P ?
