IP QoS via Differentiated Services (DiffServ)

DiffServ is an architecture providing different types or levels of service for IP traffic. DiffServ
(according to RFC 2474) offers the capability to prioritize certain traffic types depending on
their priority, thereby, accomplishing a higher-level QoS at the expense of other traffic
types. By prioritizing packets, DiffServ routers can minimize transmission delays for time-
sensitive packets such as VoIP packets.
The device can be configured to set a different DiffServ value to IP packets according to
their class-of-service: Network, Premium Media, Premium Control, Gold, and Bronze. The
DiffServ parameters are described in ''Networking Parameters'' on page 291.

Network Configuration

The device allows you to configure up to 16 different IP addresses with associated VLANs,
using the Multiple Interface table. In addition, complementing this table is the Routing table,
which allows you to define routing rules for non-local hosts/subnets. This section describes
the various network configuration options offered by the device.
For Voice and Data routing functionalities, the device needs to be configured with two
mandatory LAN IP addresses, one for each of the following interface services:
Voice (VoIP) and management functionality ("OAMP + Media + Control")
Data router functionality with security ("Data")
The default IP addresses (in subnet mask 255.255.255.0) of these LAN interfaces are listed
below:
Voice (VoIP) and Management: 192.168.0.2 (default gateway is 192.168.0.1, i.e., the
interface of the data)
Data: 192.168.0.1 (default gateway is 0.0.0.0)
