That can provide the load sharing/balancing plus the other network management functions that you will need. I'd suggest contacting Dennis Burgess or Butch Evans and paying either of them for a few hours of consulting services now so you can get a first-pass network design that can be fine-tuned later. It will save you a lot of time and frustration and give you the knowledge and confidence that you need now to move forward efficiently. > If you know someone that would be good help in putting this idea together > please feel free to have them contact me.
