3.3.1.2
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 "0 0 0 0 0 0".
2. Expedited Forwarding (EF referred to RFC 3246)
