Testing and validating the virtual EPC with Solver – how to succeed with the virtual transition

Ensure your virtual EPC investments really scale and perform

The transition to the virtual EPC brings new challenges and complexities to MNOs. Can virtual infrastructure and service solutions cope with the elastic demands of scaling up and down, in real-time and depending on traffic?

Stringent performance and functional testing is required to ensure that subscribers and connected devices receive the same performance as with previous generations, and, as traffic volumes continue to grow, that the complete system can cope with the expected throughput and service demands.

Solver provides a complete solution test and validation solution for the virtual EPC, allowing MNOs ensure performance delivery and optimisation, for launch, in-service operation, and for iterative releases and updates following agile, DevOps processes.

Highlights include:

  • S1 / SGi interface connectivity
  • S1-MME interface with control plane traffic
  • S1-U interface with data plan traffic
  • eNodeB, user and UE behaviour
  • Stateless / stateful modelling, based on application
  • Streaming traffic or packets per second / size
  • Emulation with real user identities, ensuring accurate modelling
  • Bulk traffic generation and emulation
vEPC transition

Solver – supporting the vEPC transition

Solver enables testing of the vEPC from a variety of perspectives and with flexible scale to mirror elastic growth. It provides emulation of the eNodeB and external networks, such as the IMS and internet, for example. A key difference is that this enables real traffic to be generated, from real user identities and then validated against the desired target network.

Automated test and validation

Solver provides an automated test and validation solution for the virtual EPC, that mirrors and supports the release cycle in virtual environments. It emulates elastic, volatile demand due to the scaling, addition and modification of virtual infrastructure service components. It can be used to test the complete vEPC, to provide “wrap around” testing, or to selectivity test elements in isolation, providing a comprehensive and flexible solution.

Solver makes a vital contribution to the performance of your business. The flexible solution for independent test and verification of systems and networks offers high performance, scalability and the automation of complex test scenarios.
