The simple solution is to increase the CIR and pay the
network vendor more money. I believe, however, that internetworks
are there to provide users with reliable and responsive service to
applications. If you need 64 kbps to do that, you need a 64 kbps
CIR, which might start to approach the costs of having your own
dedicated bandwidth. The bottom line is that with your own dedicated
bandwidth, you are master of your own destiny and have a degree of
certainty over how your internetwork will perform. It all depends on
the nature of the traffic you have to transport; if all you need to
get to users is Internet, e-mail, and occasional file transfer
capabilities, frame relay or some other shared network solution
might meet your needs. If you have to deliver mission-critical
applications and therefore need guaranteed uptimes and response
times, you need your own bandwidth. |
