3.4.1.2 Layer 3 / Diffserv
Diffserv assigns a class of service to an IP packet by adding an entry in the IP header.
Traffic flows are classified into 3 per-hop behavior groups:
1. Default
Any traffic that does not meet the requirements of any of the other defined classes is placed
in the default per-hop behaviour group. Typically, the forwarding has best-effort forwarding
characteristics. The DSCP (Diffserv Codepoint) value for Default is "000000".
2. Expedited Forwarding (EF referred to RFC 3246)
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
"101110".
3. Assured Forwarding (AF referred to RFC 2597)
