My IDT driver uses these on VC open to set the VC CBR or VBR parameters, for example. It is also possible to install sysctl variables into a driver and use them to set the VC parameters. This is far from elegant, but might be useful if the program creating the VC does not set the traffic parameters. Of course, it is good to have hardware that supports cell rate control. > Yes, but the PCA200E does not support rate limiting (i.e. traffic > shaping). (Well, it supports it, but only for one PVC).

Usually, one wants to keep every good PDU that arrives :-) All the best, -Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
