Resources for designing redundancy and load balancing among data centers

Hello all,

I'm looking for resources for designing redundancy and load balancing between two physically separate data centers. I'm looking for some "best practice" links, tips, or recommendations. Any suggestions are appreciated!

Thanks.

The router will automatically load balance over, up to 4, equal cost paths, but on a per session basis so you will not necessarily see equal utilisation.

You can force the router to do load balancing on a per packet basis by disabling fast switching, ie no ip route-cache, on the interface but this is not recommended as it will severely impact the performance of the router.

I think that we can do per packet load balancing by using CEF.

Please go to the following URL:

Also, you may need local director or distributed director. What resource/application is availalbe in the data centre? (e.g. http server, ftp server, TN3270 server, and so on)

Thanks for the response. Multiple resources need to be supported in this data center (or, centers). HTTP, FTP, SMTP, POP, NFS are just a few services, for example.
