IP Network Parameters
Expedited Forwarding is used for voice (RTP streams) by default. It effectively creates a
special low-latency path in the network. The DSCP (Diffserv Codepoint) value for EF is
"1 0 1 1 1 0".
3. Assured Forwarding (AF referred to RFC 2597)
Assured forwarding is used for signaling messages by default (AF31). It is less stringent
than EF in a multiple dropping system. The AF values are containing two digits X and Y
(AFXY), where X is describing the priority class and Y the drop level.
Four classes X are reserved for AFXY: AF1Y (low priority), AF2Y, AF3Y and AF4Y (high
priority).
Three drop levels Y are reserved for AFXY: AFX1 (low drop probability), AFX2 and AFX3
(High drop probability). In the case of low drop level, packets are buffered over an extended
period in the case of high drop level, packets are promptly rejected if they cannot be for-
warded.
