Recommendation ITU-T H.248.22 describes a package to enable the media gateway controller (MGC) to indicate to the media gateway (MG) to use or not to use network resources associated with a shared risk group when setting up connections. When network connections are associated with ephemeral terminations in the MG, certain resources are used. A failure in the MG may result in the loss of certain groups of resources, whilst other groups of resources remain unaffected. The resources that share a risk of failure are called a shared risk group. A shared risk group is simply a grouping of the network resources (e.g., IP interfaces) sharing the same risk of failure. Each shared risk group could, for example, contain a number of IP interfaces located on the same piece of hardware. If a resource failure occurs, only terminations in the shared risk group corresponding to the failed resource are affected while other terminations are not.
