Hi all,
After studying QOS issues for a bit today I have a question about non-ip
traffic and rate limiting or policing as it may be called by some.
GTS and CAR/DCAR only handle ip traffic from what I have read and the
threads on groupstudy. Now what if you wanted the same functionality with
other protocols what would you use?
In order to be specific in the types of traffic including things such as
IPX, WWW, DLSw, and IP it looks as if Custom-queuing with the byte-count is
my only choice? But it seems to only buffer or rather queue the packets
until the queue fills up then it drops them. So to give DLSw traffic 50% of
the bandwidth I would set the queue to 1/2 of the bandwidth of the serial
link??? This would then be filled only if traffic was exceeding the link
capacity. This does not guarantee 50% of the link but give 50% of the buffer
space to that traffic only when congestion is experienced so is it really
getting 50% of the bandwidth I think not, but I read that this is how to
deal with non-ip traffic?
It seems a sub-optimal choice considering if it was IP only I would be able
to CAR, DCAR, or GTS.
Any thoughts?
