Basic question — and apologies for this. But we all have to start somewhere, don’t we?
I need to estimate bandwidth upgrade needs on a number of Frame Relay links each of which are at present 128 access speed (consisting of 2x64k channels), and 2 x 64K PVC’s each. The links are Point to Point connections to a Corporate Office. Corporate office Frame connection to Comms Provider is 1280k.
The Corp. Office provides access to the Internet for each Centre. Our need is to provide access to each Centre to an additional service: Browser based access to an internet training site. Vendor states that 28.8 K fine but ideally 50kbps is needed.
Surely, I am miscalculating: I have calculated that 25 simultaneous users at any one Centre needing 50Kbps, totals 1250kbps additional bandwidth needs to be added to each 128k Frame Link (and of course the Corp Office link upgrade is equal to a total of all these sep. upgrades).
Clearly I missing something — and I have a feeling (can you tell yet I’m not a comms person ?) — that the key is that 128K Frame allows more than 128kbps. It’s got to be a simple misunderstanding of Frame capacity. IF not, we are upgrading each link by more than 9 times its present size, for 25 users to simultaneously access slightly more than a standard single 28.8 connection.
What have I missed?
Thanks,
