4.3 Choosing the Appropriate Networking Type
The choice of the appropriate topology depends on the following factors, among
others:
• Number of locations
• Distance between the locations
• Calling rate between the locations
• Networking equipment required
• Existing data network (see AIP documentation)
• Scope of performance required
With virtual networking, the costs incurred consist of the basic charge for connec-
tions and DDI numbers and the charges per call, while a dedicated line incurs only
fixed costs (for the rental of the leased line for example). The following compari-
son (
Fig. 1.22 ) shows that virtual networking is better suited to systems with lower
calling rates while networking with leased lines can be more advantageous for
higher calling rates.
As
Fig. 1.20 shows, combinations of both networking types are also possible.
