ECOTEL 3G 16.1. Revised: 1 March 2011.
Example:
5 . 1 . 8 B A N D W I D T H C O N T R O L
In many implementation scenarios, the ECOTEL in router mode (e.g. as DSL router) sends voice and data traffic
through a connection with limited bandwidth. This can lead to lost voice packets that arrive too late to be used in
the voice stream. To avoid lost packets, this QOS setting prioritizes packet transmission. You must set the priority
for voice signaling and for the voice packets. That means you must prioritize SIP/H.323, RTP and RTCP. You will
find the ports used in Table 5.18, in the following entries:
H225Port
SipPort
VoipRtp Port
VoipRtpPortSpacing
Different ports can be used for RTP and RTCP, depending on the configuration.
The parameter
VoipRtpPort
shows the first RTP port used. The corresponding RTCP port is the next one up.
The parameter
VoipRtpPortSpacing
shows the next RTP port (RTP port + port spacing).

interface <interface> bandwidth <bw> priq
Defines the interface for which the rule applies.
<interface>
Sets the interface for which prioritization applies (e.e.
pppoe0
).
<bw>
Sets the bandwidth that is available on the interface in Kbit/s (e.g. 256K).
priq
Priority qeueing. A higher priority class is always served first.
class priq <interface> <class> root priority <prio>
Defines the priority of the filter entries.
