Title : "EXP field" renamed to "CoS Field"
Author(s) : L. Andersson
Filename : draft-ietf-mpls-cosfield-def-01.txt
Pages : 12
Date : 2008-06-04
The early MPLS documents defined the MPLS format, this definition
includes three bit field called "EXP field". The documentats leaves
the exact description of how the EXP field should be used undefined,
it is said said to be for "experimental use".
The EXP field has from the start been intended to be used for "Class
of Service". At the time the documents were published the use of
such a CoS field were considered not to be defined well enough and
the field were left for "Experimental use".
To avoid misunderstanding about how this field may be used this
document re-introduces the name "CoS field" for this field. In doing
so it also updates documents that defines and uses this field.
