Most Innovative Signal Control Platform: NetNumber TITAN Company: NetNumber, Inc Email: sales@netnumber. com Website: http://netnumber. com/products/titan/
NetNumber was founded on innovations in addressing and routing technologies. Kim Gibbons talks us through the company and its revolutionary solution. Innovation is the heart and soul of NetNumber. Nearly two decades ago, the telecom industry was in a panic as vendors declared “voice would be free” and phone numbers would disappear. The Plain Old Telephone System (PSTN) and the SS7/ C7 signaling network on which it was built were declared destined to disappear -- to be replaced by IP, or Internet Protocol. NetNumber founder Douglas Ranalli believed this migration from legacy to next-generation networks would not happen overnight, and would not be as easy as some vendors stated. He founded NetNumber in 1999 with the goal of simplifying the migration of SS7/C7 signaling to next-generation signaling while enabling carriers to continue to use telephone numbers to identify subscribers. Doug had the foresight to define a software platform that could accommodate the signaling and routing protocols of the day, and be robust and flexible enough to accommodate protocols that had not yet been defined. Today, NetNumber TITAN provides a common, virtualized infrastructure for all signaling control, routing policy enforcement and subscriber database services in the network. The company’s ground-breaking work has expanded to focus on four pillars of innovation which radically simplify signaling and routing control in a telecom operator’s core network. Such simplicity enables the operator to more quickly introduce new revenue-generating services while also reducing OPEX and CAPEX investments. These pillars of innovation are: 1. One common platform with multi-protocol interfaces. NetNumber TITAN provides a Centralized Signaling and Routing Control (CSRC) platform for all signaling control services -- ENUM/DNS, SIP, DIAMETER, RADIUS, SS7/ C7 and SIGTRAN. TITAN supports the most comprehensive suite of signaling protocols in the industry. 2. Flexible signaling interworking. With the slow transition to next-generation network architectures, most telecom operators will need to provision, operate and manage their converged networks for the next 15-20 years. TITAN enables the smooth interworking
between legacy and emerging signaling management services and protocols. While many vendors are choosing to end-of-life their signaling products for legacy protocols, NetNumber is committed to supporting the transition to next-generation networks. 3. Distributed, in-memory database. NetNumber is the only vendor to integrate a scalable and distributed, in-memory database into its CSRC platform. This enables TITAN to serve as a central point of provisioning for the subscriber data with real-time distribution of the data to a constellation of geographically distributed edge servers. TITAN is highly scalable, and can support any size subscriber base to support any size network. 4. Programmable logic interface. As the network evolves with new services such as WebRTC or BSS services, telecom operators need the flexibility that comes with customizing logic interfaces. The TITAN service logic can be modified in the field to support locally defined logic requirements without waiting for a new software release. The result is a dramatic acceleration of introduction of new functionality into the network. Today, the telecom industry is in a panic around security. Operators are concerned with protecting their SS7 signaling networks, noting repeated incidents and the impact of such incidents on the operator’s brand and reputation. Concerns about the security risks of Voice over LTE (VoLTE) and IP Multimedia Subsystem (IMS) networks are also growing, as operators seek solutions to ensure quality of service, prevent network failures, and block malicious attacks. The security of the telecom operator’s signaling network is at risk today due to several factors, including new operators requiring mobile roaming interconnection and the use of femtocells with direct signaling access. With up to 20-30 billion network connected devices, applications and sensors predicted by 2020, the Internet of Things (IoT) represents a critical challenge for operators in terms of signaling and security. The very high level of authentication and registration events, signaling traffic bursts, unpredictable effects of these unmanaged devices, complex network 60 l CV Technology Innovator Awards 2016
interconnection scenarios, and possible hostile hacker attacks all pose real threats to networks supporting IoT traffic. Telecom operators need a new, highly secure signaling architecture protected by a robust multi-protocol signaling firewall. Recently, NetNumber announced the industry’s most comprehensive multi-protocol signaling firewall on its TITAN CSRC platform. Building on last year’s delivery of the NetNumber SS7 Firewall application, NetNumber is now providing the same level of firewall capabilities for all signaling protocols including the addition of Diameter, SIP, HTTP and DNS/ENUM. As these firewall applications can be combined seamlessly with other NetNumber applications such as an STP, DSC, HSS or HLR on the same TITAN platform, telecom operators have an unprecedented level of multi-protocol signaling protection, flexibility and operational uniformity in a platform that can reduce OPEX and CAPEX costs and improve efficiency. A comprehensive monitoring function completes the NetNumber Multi-Protocol Signaling Firewall to offload data to external systems for big data analytics, reporting, statistics and other auxiliary functions used by telecom operators to build a complete next-generation signaling protection capabilities in today’s complex and geo-dispersed networks. NetNumber is playing a leading role in the GSMA Fraud and Security Group (FASG) to standardize the requirements for signaling firewall solutions. The requirements in the resulting document focus on two aspects to be supported by a Signalling Firewall solution: • The specification of rules in a vendor-agnostic and human readable ‘pseudo-code’ to provide operators the same type of protection for vulnerabilities irrespective of the vendor of the firewall solution. • The generation of standardized content and formats of logging data that support the exchange of information between operators about threats and new vulnerabilities. The firm expects to announce additional innovations in signaling security in the coming months, and overall has an exciting future ahead of it.
