3.5.8 Smart Dial Control (SDC)
Smart Dial Control (SDC) is a dial-on-demand backup technology used for
interconnecting routers via PSTN, ISDN or 3G. The ‘dial-on-demand’: the interconnected
routers in different networks only get communicated via dial-up manner when there are
data to be processed between them. When the link is free, the SDC will disconnect the
link automaitcally. As in some circumstances, the connections and communications
between routers only happen when there is information to be processed, the information
under transmission often features irrelenvant time, abruptness and few data. The SDC
service at this momenet provies flexible economical and highly efficient solutions for this
implementation. In real applications, the SDC which often exists as a backup path keeps
the service running smoothly when the communmication is down due to broken links.
The SDC module often implements the following services:
Dial backup service
The invalid master link (interface) triggers the dial backup: When the master link
(interface) fails for a while, the backup interface will dial up the backup link. When
the master link (interface) recovers, the backup link will be disconnected.
The overload major link (interface) triggers the dial backup: When the major link
