Network functions virtualization (NFV) and software-defined networking (SDN) are described as “disruptive” technologies. An important aspect is how to approach this disruption so that it translates into the ability to deliver services faster, without scattering the BSS/OSS stack. Moreover, from the perspective of customer service creation, technical disruption should be transparent – meaning that OSS can be perceived as the same “service factory” system, but with a much shorter time-to-market and an ability to “experiment” with new services in short cycles, thus enabling adoption of the “not afraid to fail” concept.
Many interpret the ETSI NFVI architecture as an introduction of a new silo, which may cause issues related to integration with the so-called “legacy” BSS and OSS stack.
Comarch’s approach is different – it assumes leveraging modern OSS capabilities to implement both service orchestration (thus enabling the creation of customer services, based on “hybrid” networks, combining virtualized and not-virtualized ones), NFV orchestration and generic VNF manager.
The key OSS capability is catalog-driven (model-driven) orchestration, which may drive decomposition of customers service orders into technical service orders, delegated to NFV- orchestration or “legacy” network. For NFV-based technical services, it enables to further decompose them to VNF “orchestration,” so in the end, it is possible to allocate the virtual machines capable to host virtual network functions (VNFs), fulfilling customers’ requirements.
During the demo, Comarch will show use cases for the customer service delivery, where customer services are designed in the Service Catalog (pre-integrated with Resource Catalog), and where both VNFs and PNFs can be used to model technical services. The key aspect lies in automation, based on model-driven fulfillment. The demo will show end-to-end scenarios, assuming that customer orders are captured by “traditional” BSS /CRM (product catalog based) and fulfilled on hybrid networks, including SDN and NFV domains. Another aspect, which will be demonstrated, is SDN vs. NFV centric implementation of services – showing how customer orders ultimately drive Open Flow Switch Flow entries centralized configuration with NFV orchestration.
