bandwidth on demand
- noun a system used with a switching service such as ISDN in a wide area network that allows users to send as much information as they want by automatically allocating extra channels to cope with higher bandwidth requirements
- Within a network, the capability of increasing the available communications resources as any given circumstances warrant.
