[OPENETLAB] Question: Oplets and Accelar Queue Mgt./Routing

["Vivek Sawant" <vivek@nortelnetworks.com>]

Hi All,

I am playing with an idea of influencing Accelar Forwarding from Oplets.
I am looking at an algorithm which is an extension to RED. I wonder if I
can implement it as an Oplet and combine it with Accelar IPfilter
setting to influence Accelar Packet forwarding.

My initial investigation suggests that this is not possible. Here is
why. This algorithm, like any other queue management algorithm, includes
the just arrived packet in a computation to decide if the packet should
be dropped or queued. If this computation happens in an Oplet, it is
essentially happening outside the Accelar forwarding path. Given current
Accelar filter actions, one can either choose to drop or forward a
packet (besides getting a copy of it, etc.) One cannot pull a packet
out, do computations and then give it back to Accelar forwarding engine.
(I know, it will radically slow the engine down.) So, such a queue
management algo has to be part of the Accelar forwarding mechanism.

Is my inference correct or is it still possible to implement such a
scheme through Oplets? Does Accelar support RED queues?

Thanks.
