EXFO Releases Integrated IMS-HSS Emulator

EXFO Electro-Optical Engineering released an integrated Home Subscriber Servers (HSS) emulator for Internet Protocol Multimedia Subsystem (IMS) networks. The HSS, the master database in IMS architectures, plays a critical role in the authentication and authorization of subscribers. Without proper access to the HSS, subscribers cannot access network services, resulting in significant network downtime, customer churn and loss of revenue.

EXFO's said its new hssFlex can wrap around an IMS network to provide end-to-end testing, or simply characterize single network elements such as application servers or call session controllers. Key test features include the ability to simulate real-world interactions like subscribers updating their services, subscriber services being terminated due to non-payment of bills, and characterization of the impact of denial of service (DOS) attacks on the IMS network. Like EXFO's other IMS test suites, the hssFlex complies with industry standards, but also provides the flexibility to simulate proprietary and non-complaint IMS traffic.
