600й Зюхель имеет внутри себя Линукс, со всеми вытекающими. Соотвцно, теоретически, он такое умеет. Вот тут по ссылке написано, что как-то там оно даже реализовано, но насколько я понял, просмотрев по диагонали - это фича не для ограничения кого-то конкретно, а для согласования быстрого езернета с одного конца и медленного АДСЛ с другого. Так что самый простой вариант - ставить что-то между свичом локалки и АДСЛ модемом, переведенным в режим моста, и вот на этом промежуточном звене все пляски с бубном устраивать. У меня дома, когда оно было надо, весьма успешно 5 компов разруливал старенькийкомп на древнем АМД, с каким-то компактным линуксом, Freesco что-ли.

13. What is Traffic Shaping?
Traffic Shaping is a feature in the P-660. It allocates the bandwidth to WAN dynamically and aims at boosting the efficiency of the bandwidth. If there are serveral VCs in the P-660 but only one VC activated at one time, the P-660 allocates all the Bandwidth to the VC and the VC gets full bandwidth. If another VCs are avtivated later, the bandwidth is yield to other VCs after ward.

14. What do the parameters (PCR, SCR, MBS) mean?
Traffic shaping parameters (PCR, SCR, MBS) can be set in Menu 4 and Menu 11.6 and is valid for both incoming and outgoing direction since G.shdsl is symmetric. Peak Cell Rate(PCR): The maximum bandwidth allocated to this connection. The VC connection throughput is limited by PCR. Sustainable Cell Rate(SCR): The least guaranteed bandwidth of a VC. When there are multi-VCs on the same line, the VC throughput is guaranteed by SCR. Maximum Burst Size(MBS): The amount of cells transmitted through this VC at the Peak Cell Rate before yielding to other VCs. Total bandwidth of the line is dedicated to single VC if there is only one VC on the line. However, as the other VC asking the bandwidth, the MBS defines the maximum number of cells transmitted via this VC with Peak Cell rate before yielding to other VCs.
The P-660 holds the parameters for shaping the traffic among its virtual channels. If you do not need traffic shaping, please set SCR = 0, MBS = 0 and PCR as the maximum value according to the line rate (for example, 2.3 Mbps line rate will result PCR as 5424 cell/sec.)
15.Why do we perform traffic shaping in the P-660 ?
The P-660 must manage traffic fairly and provide bandwidth allocation for different sorts of applications, such as voice, video, and data. All applications have their own natural bit rate. Large data transactions have a fluctuating natural bit rate. The P-660 is able to support variable traffic among different virtual connections. Certain traffic may be discarded if the virtual connection experiences congestion. Traffic shaping defines a set of actions taken by the P-660 to avoid congestion; traffic shaping takes measures to adapt to unpredictable fluctuations in traffic flows and other problems among virtual connections.
