The Speed Limit is a feature that allows IPRTR to reduce the rate of its outgoing datagrams on a specific IP resource. Main usage is to reduce speed to safe values in the presence of VOICE packets, while leaving full speed for data transfers when the voice isn't present.
The Speed Limit can be activated setting the
OUTSPL parameter to YES in the IP
resources. The maximum speed is set in the OUTSP
parameter. Generally, this parameter must be set to a value slightly lower
than the maximum speed in the upload of the ADSL/HDSL line (e.g.: if the
ADSL line has a maximum speed of 256 Kbit/s the OUTSP
parameter must be set to 240).
Enter into the Abilis control-program or open the configuration file with the Console configurator and type the following commands.
| s p ip-3 outspl:yes outsp:240 | Activate the Output Speed Limit and configure the speed limitation value. |
| s p iprtr acl:yes cos:enabled cosbalance:yes | Configure the Access List activation, enable the Class-Of-Service management and the Class-Of-Service Balancing. |
| a ipacl pr:0 type:permit ipcos:high tos-i:*-d prot:udp sres:int sa:* da:* spo:* dpo:* | Add the standard IPACL that assigns high priority to voice packets. |
| save conf | Save the configuration. |
On a working Abilis, you must initialize the IP-3 (init res:ip-3) and the IPRTR resources (init res:iprtr). The changes on IPACL table are immediately active.
