“In traditional networks, when the certain level of supplier trunk capacity is reached, SIP Redirect is activated, and traffic is rerouted to next Supplier trunk in line. On the other hand, there is the Diameter driven Credit Control, when the set limit for the maximum allowed traffic is met, traffic is re-routed to next Supplier trunk in line.”
In the last part of my blog, we will discuss SIP-driven routing controls enriched by the Diameter protocol potential. This part may be a bit more technical in nature, but don’t worry; as always, we are in your corner.
While the traditional SIP Redirect Routing makes a substantial part of Network functionalities itself, Diameter Routing is a new way of Routing Control. Both approaches control the Routing functionality on the Network but differ in the cause of Routing decision-making. SIP Redirect re-routing functionality is a network functionality triggered when supplier trunk conditions are met. Opposite of SIP Redirect, based on pure Network set conditions, Diameter-based solutions rely on Business rules and traffic control.
For example, in traditional networks, when the certain level of supplier trunk capacity is reached, SIP Redirect is activated, and traffic is rerouted to the next Supplier trunk in line.
On the other hand, there is the Diameter-driven Credit Control. When the set limit for the maximum allowed traffic is met, traffic is re-routed to the next Supplier trunk in line.
Contrary to traditional SIP redirect, diameter-based routing has additional ways of routing control exclusive to this kind of routing:
