The values given in the table are the default settings of the loadware. These
settings fulfil the OSCAR specifiactions. You can change the L2 priority with
WBM > Explorers > Network Interfaces > LAN1 (LAN1) > Edit LAN1 Interface
The values can also be changed via the appropriate AMO.
IMPORTANT: If you change the values for HG 3500 with AMO CGWB you have
to reboot the corresponding gateways with AMO BSSU.
There are a number of other common prioritization methods, which are managed
in the affected routers:
•
Prioritization based on the IP address
The entire traffic from an interface is given (identical) priority. Traffic from
IPDA components can thus be given a higher priority than other traffic by
specifying the IP address.
•
Prioritization of a port (socket) range
In this case, the IPDA-specific ports (see
higher priority than other ports in the network.
It is essential that the signaling and payload ports be taken into account
here. This method is not recommended given the size of the port range for
payload.
•
Prioritization of specific services (TCP, UDP)
Although prioritization of UDP traffic, for example, in the network would have
a positive effect on the payload, it would restrict signaling (TCP/IP). This type
of signaling is therefore NOT suitable for IPDA. It impairs system availability.
The actual bandwidth per active payload connection depends on the selected
encoding algorithm, the specified sampling time and on the fact if the feature
"Signaling and Payload Encryption (SPE)" is activated.
3.5.1 Encoding
For example, the following encoding can be selected:
•
G.711 (PCM) with support for Annex 1 (packet loss enhancements) and
Annex 2 (Voice Activity Detection with Comfort Noise Generation).
•
G.729A voice compresses to 8Kpbs.
