sending and receiving file from socket

[TheCPUWizard]

Mike,

I have lng disagreed with the "guarantees" of TCP. Primarily from a syntactical point of view.

Consider an application pair where the sender transmist 1MB over a slow complex routing scheme. At some point in time the receiver begins getting data. We wait until 500KB has been received, then do something "nasty" link crash the network, or event the receiving application.

Clearly not all of the data will be received. Thus (as phrased by you and many others), the "guarantee" is not met.

I (and many others) prefer that the syntax be reversed (and it is in many publications to be:

TCP guarantees that no bytes will be duplicated or dropped from the middle of the stream, nor will any bytes be received out of order.

Sounds silly, but you would be suprised the number of people I have run across who will do a "blind send" of data over TCP and do NO checking because "TCP guarantees reliable delivery"....

That's a fair criticism of the way many people (myself included) have described the guarantees of TCP. As you say, delivery is not guaranteed. Rather, there is only a guarantee that if any one byte is received, that all bytes before it have already been received without duplication.
