Virtualization, Software Defined Networking (SDN) and Network Function Virtualization (NFV) are allowing Service Providers to improve their network programmability and agility when rolling out new services and creating opportunities for revenue generation at a reduced capex/opex.

In a Hybrid or pure Virtual Network, problems with components such as applications, network interfaces, control and data plane traffic, orchestration etc. have a deep impact in the overall customer experience. While migrating from a physical to a hybrid or pure virtualized network, Service Providers and Devops teams struggle to manage the different aspects of the overall customer experience. Test Automation and Orchestration play a key role in alleviating the pain.

Rebaca’s Test Orchestration solution – ABot helps Communication Service Providers, OEMs and Platform Vendors address these pain points by combining the best practices of Test Automation, CI-CD and virtualized deployment.

ABot uses the concept of BDD (Behavior-driven development) to define test scenarios in high-level language for spec-driven acceptance criteria.  You can schedule to execute these test scenarios through a CI engine and prepare for deployment based on the results.

The VoLTE use case is the traditional system integrator’s nightmare. In order to accurately measure the KPIs, ABot provides the capability of simulation of key nodes, Data collection and analysis of results. Test cases can be augmented and modified from existing library. Test cases range from Signaling Validation, Multiple Codec Characteristics, Voice QoS and QoE(MOS) – under different reference conditions as well as the capability of doing comparative studies under these conditions. The reference conditions refer to the variations in mobility, network congestion, multi-vendor characteristics. Benchmark testing and comparison with OTT VOIP services are also covered for the ability to make business decisions.

The LTE Access network is the single biggest advancement toward high speed data mobility. The use case ranges from the traditional voice, video, text but with data and variable QoS, with greater mobility and higher quality. ABot contributes to these advancements by providing a means to test the LTE access network in the following areas for performance benchmarking and functionality: UE Attach/Detach, Idle Mode, Authentication, Security Mode, EMM and ESM Procedures, Handover and Tracking Area Procedures. The focus of the test cases are in being able to measure the capability of the network in terms of services and the resilience of network when challenged by load and mobility requirements.

The IMS network allows for the convergence of different kinds of networks. The ABot Test cases allow for the testing of various aspects of the IMS networks – Registration, Authentication, Call Control, Service Discovery and Triggers, Messaging, Application Servers, Third Party Call Control and Conferencing. The focus of the test cases lies in testing of the network from the point of view of convergence and resilience of the same network, when challenged by load.
