Not all Routing Control Agents are created equal

Communications Service Providers face difficult signaling management challenges created by the rapid evolution of their networks. These need to be addressed because if they’re not, as has already been established, the result can be significant problems. A number of leading including O2 in the UK and Orange in France have already experienced signaling storms in their LTE networks that have resulted in outages. In North America, Verizon experienced an LTE-related outage directly related to poorly managed diameter routing and interoperability problems between IMS and the packet core. One outcome of the above reality is that Diameter Routing Agents have become established components in the infrastructure landscape. The first generation of “static” DRA solutions widely evident today falls short of the required mark. These boxes cannot adequately meet the multi-source, multi- destination signaling challenge they need to address. Static routers perform effective signaling control only in a fixed environment where everything is known in advance. But when new destinations and sources often reliant on protocols other than diameter come into play, there is an inherit resistance in using static boxes to enable them. As a result new services may take a long time to be supported, leaving operators to try to find workarounds that, even if they succeed in the short term, ultimately put service availability at risk. This is because static routers cannot manage service node signaling. We believe that effective Routing Control requires as standard the flexibility to mitigate different flavors of diameter specific to the service delivery system in question. It requires the modularity to support and quickly introduce new Application Function platforms (such as SPRs, UDRs, SPRs, OCSs and RealTime analytics) without software updates and it requires logical extendibility to implement enrichment, degraded mode, ocf, micro quota strategies, etc. at a later stage or where necessary. The flexibility to bridge and translate into different signaling protocols like Diameter, Radius, SS7, Web Services, and others is mandatory. Routing Control from DigitalRoute enhances and augments existing DRA solutions by increasing integration modularity. In this way, CSPs can leverage DigitalRoute Routing Control to gain the ability to be flexible in deploying logical use-cases where a very short turnaround time is required. Furthermore, DigitalRoute Routing Control is a uniquely revenue-oriented, policy- and charging-centric Diameter Routing solution. It specializes in support for revenue-oriented applications such as Gx, Gy, Rx, S9, and Sp interfaces using standard provisioning of subscriber data via SOAP to drive Routing Control. This allows Network Operations to open up DRA functionality to IT without sacrificing control, a critically important benefit because IT can use the DR agent to extract and control charging information drawn from network elements without needing direct access to the elements themselves. Only Routing Control from DigitalRoute affords this advantage. With DigitalRoute Routing Control, users can keep their service delivery chains healthy with a tool that protects the delivery process and mitigates the differences that may be inherent in existing IT architectures. - See more at:
