Hi Siamack,
Thanks for responding quickly. I do understand that RPR is
frame based technology but I am wondering if the same approach can be
applied to point to point too. Here is the background. Currently, we are
using POS and have 1+1 APS redundancy i.e. we have two pairs of fiber cable,
on event on failure of one, automatic switch is done to the functional pair.
Now, that we want to use Gige, I was wondering if we could find some
standard that could address this problem. RPR (particularly IPS portion)
looks very similar to what would be practical. I feel that point to
point is a special case of ring (well a ring with two nodes).
Could you point me to some standard that would address this more
than RPR? I feel like APS there should be some standard that addresses
ring as well as point to point resieliency (multihoming does not have the kind
of availablity that is required critical network design).
