Re: OT: Is WAAS that bad?

Hi Travis,

Thanks for the response.
But I thought regardless using WCCP or in-line, we still need to make sure the traffic flows symmetrically in the network.
My Cisco SE recommends using WCCP instead of inline. He said fail to wire will not work if software hangs/crashed. Other than that, it will be more difficult to isolate WOC when doing problem determination because all traffic pass through the device.

BTW, do you know if there is any blog/web thats compare the app supported by Riverbed vs WAAS? I tried googling but couldn't find, may be there isn't any.

Regards,
Alexander Lim
