WAE WAAS question

[marcusbrutus]

Hi Experts,

I had some experience working with other optimizers which normally utilize tunnel tcehnology.  With this tunnel technology, branch and core optimizers are able to determine when to and not to optimize traffic (eg. there is no tunnel compression peering).  I read that WAAS however doesn't use the tunnel concept.  If this is the case, if a remote branch has a failed WAAS, how will the core WAAS know not to optimize traffic?

Going through the configs of both branch and core WAAS, i believe the settings are vitually the same.  With WCCP services 61 and 62 with redirect in and out enabled and running on the router and transparent interception enabled on the WAAS where standard application interception is in place, I can't help but think that the core router would continue to compress data going to the failed WAAS branch.

Thanks in advance.

Hi,

   If WAAS in branch office is offlince, then on Core side WAAS, traffic will be pass-through and not optamized. This is the default behavior in WAAS. Thanks.

Would that still be the case even without a WAAS Central Manager?   How can the core WAAS know that it should not compress/optimize data to the problematic site?

We do not support deployments without Central Manager, However in this case Central Manager has no role, WAAS do a TFO auto discovery for each flow for optamization, Since the remote office WAAS will be down, Auto Discovery will fail and connection will go in pass-through.
