Configuring Quality of Service
A.2 Traffic Shaping
A solution for such a situation is limiting the bandwidth of low-priority TCP
connections (such as the file download).
A.2d Differentiated Services Code Point Settings
In order to understand what DSCP is, one must first be familiarized with the
Differentiated Services model.
Differentiated Services (Diffserv) is a Class of Service (CoS) model that
enhances best-effort Internet services by differentiating traffic by users, service
requirements, and other criteria. Packets are specifically marked, allowing
network nodes to provide different levels of service, as appropriate for voice
calls, video playback, or other delay-sensitive applications, via priority queuing
or bandwidth allocation, or by choosing dedicated routes for specific traffic
flows.
Diffserv defines a field in IP packet headers referred to as the Differentiated
Services Codepoint (DSCP). Hosts or routers passing traffic to a Diffserv-enabled
network will typically mark each transmitted packet with an appropriate DSCP.
The DSCP markings are used by Diffserv network routers to appropriately
classify packets and to apply particular queue handling or scheduling behavior.
The FiOS Router provides a table of predefined DSCP values, which are mapped
to 802.1p priority marking method. Any of the existing DSCP setting can be
edited or deleted, and new entries can be added.
1. Click Quality of Service at the top of the Home screen, then click DSCP
Settings. The "DSCP Settings" screen appears.
