ABSTRACT:
A media gateway controller (MGC) is described herein that implements a shared risk group package to control and prevent a media gateway (MG) from establishing redundant links like a primary link and a secondary link that use resources that share the same risk of failure. Essentially, the MGC uses the shared risk group package to control which resources like ephemeral terminations are used by the MG to establish the primary link and the secondary link such that if any of the resources associated with the primary link fail then the secondary link remains operational within the MG and if any of the resources associated with the secondary link fail then the primary link remains operational within the MG.
