Re: Application issue over two ISP

The problem with the below solution is that it does not address the return
traffic problem nor the convergence time issues for the Internet. You
would also have to implement some type of natting solution, or script a
route policy change (assuming you're running BGP with your providers) to
control the inbound path from the Internet.
 
If the application is critical to business function you should consider
some type of direct PTP partner type connectivity. You can control path
much better, it will be more stable, and the failover times will be
greatly improved.

I feel we can implement cisco new protocol technology ( PFR) .. This
protocol purposely developed for Application.

Performance Routing (PfR) complements traditional routing technologies by
using the intelligence of a Cisco IOS infrastructure to improve
application performance and availability. This technology can select the
best path for each application based upon advanced criteria such as,
reachability, delay, loss, jitter, and Mean Opinion Score (MOS).
Performance Routing can also improve application availability by
dynamically routing around network problems like black-holes and brownouts
that traditional IP routing may not detect. The intelligent load balancing
capability of Performance Routing can optimize path selection based upon
link utilization and/or circuit pricing.

Application issue over two ISP

Hi Guys,

I have a scenario -

CE -------ISP1
|
|
|
ISP2

users behind CE connect to remote application ,
Now issue is if ISP1 LINK or ISP1 goes down I have times less than 4 sec
for application to go via other link so that users are not imacted.
So can there be any solution for traffic to converge before 2 request
timeouts , so that my application users are not impacted.
