Comarch OSS Suite
The Comarch NFV/SDN solution is based on Comarch OSS Suite, which enables CSPs to provide customer services on top of the hybrid network built from “legacy” components and distributed NFVIPoPs connected by an SDN and non-SDN network.
NFV/SDN related transformation should not lead to the introduction of yet another silo. That is way Comarch’s unique approach to NFV/SDN is based on OSS modernization, allowing hybrid network management. The ability to drastically speed up the process of new service introduction, and at the same time to reduce costs thanks to a high level of the automation, is essential for network operators planning a successful NFV/SDN transformation. That’s why Comarch’s solution employs an end to end model driven concept, where models are managed in service and resource catalog. The solution enables VNFs and Network Services to be treated as “building blocks” (which can be on-boarded), from which completely new customer services or versions of existing ones can be created quickly. Comarch NG Service Fulfillment has been modernized to be able to implement model-driven end to end orchestration comprising service orchestration (customer order decomposition to technical services), for NFV/SDN technology MANO orchestration and for virtual network functions driving the VNF instantiation process. Based on TMF SID model, this end to end process can be realized in multi-domain networks where third party orchestrators can be orchestrated by the Comarch solution.
One of the key elements of the solution is a modernized network and service inventory system, which can provide the end to end view of the multi-domain, multi-technology network. The network inventory is pre-integrated with OpenDaylight SDN Controller, enabling the development of “smart” controller applications that can take advantage of both the end to end view of the network and the customer service view. In respect of NFV technology, the inventory manages not only the network of a single data center, but provides the topology of a distributed network comprised of many NFVI PoPs. Within these, the MANO functions can distribute VNF instantiations orders delegating VIM related operations to OpenStack, with which Comarch solution is pre-integrated.
Comarch Service Assurance has been modernized to manage not only hybrid-based services, but also purely NFV-based implementation. It is essential to take advantage of Comarch Service Assurance’s ability to correlate the “black box” view of the service and network function with information from NFVIs. This is crucial, for example, in deciding whether performance degradation of VNF is due to insufficient NFVI resources, or to some specific VNF configurations. This means the system is capable of distinguishing whether VNF scaling or another NFVI related operation (such as virtual machine migration) is needed for self-healing, or whether specific VNF configuration action must be taken to ensure good quality of services and thus appropriate customer experience.
Comarch’s approach to NFV/SDN transformation via OSS modernization has the added benefit of BSS ready to use pre-integration. From the BSS perspective, whether NFV/SDN technology is used or not the network should be transparent as long as it serves customers’ needs. On the other hand, but on the other hand this transformation should bring about a significant time to market reduction in terms of introducing new customer products and services.
