ADSL2+ 4-Port Ethernet USB Wireless-G Router - User Guide

There are some additional terms you should get familiarize with:

• Ingress: Packets arriving into the router from a WAN/LAN interface.

• Egress: Packets sent from the router to a WAN/LAN interface.

• Trusted mode: Honors the domain mapping (ToS byte, WME, WLAN

user priority).

• Untrusted mode: Does not honor domain mapping. This is the default

QoS setting.

• Traffic Conditioning Agreement (TCA): The TCA needs to be defined for

each interface:

– Ingress mappings (Domain =>CoS)

– Egress Mappings (CoS => Domain)

– By default, all interfaces are in Untrusted mode.

• Shaper

4.5.26 Egress

For packets going out of the router, the marking (CoS) need to be translated to the mappings

understood by the network domains. The reverse CoS and domain mapping is configured using

the Egress page. This page is access by selecting Egress on the Advanced main page under QoS.

4.5.26.1 No Egress Mode

The default Egress page setting for all interfaces is No Egress. In this mode, the domain

mappings of the packets are untouched.
