Description
DSCP field
Range: [0...63]. DSCP (Differentiated Services Code Point) uses
the first 6 bits of the ToS (Type of Service) field in the header of IP
packets for packet classification purposes. The bit pattern in the
field indicates the type of service and forwarding behavior at the
next node. With 26 bits, up to 64 network service types can be
defined. RFC 2724 (see - http://www.ietf.org/rfc/rfc2474.txt)
describes the Differentiated Services (DS) field and the DiffServ
Code Point. See also the note on Differentiated Services later in
this chapter.
