A bit stubby, but a good start

New page

The '''end to end principle''' is the name of a design philosophy used in decided where (in functional as well as locational terms) to implement things such as reliabilty in a [[communication network]] system.

It says that implementing some function at too low a [[architecture#Architectural techniques|level]], or too local a [[scope]] is a waste of energy (as well as introducing useless complexity, always a bad thing).

For instance, in a [[packet switch]]ing network, protecting the data ''between'' switches is useless, since it can still be damaged while ''in'' a switch. It it better for the source [[host]] to compute a [[checksum]] on the data while it is still inside the source; this can then be checked inside the ultimate destination host, on arrival.
