2 If providing innovative services and a seamless digital experience are your company s competitive edge, don t let growing operational costs or network limitations impede your ability to compete with other CSPs and OTT players. Software Defined ing (SDN) and Function Virtualization (NFV) are the latest disruptive technologies, allowing telecoms businesses to meet the challenges of the digital era and Internet of Things (IoT) head on. Lower OPEX and CAPEX can unleash service and application innovations to increase network investment monetization. The long-term vision: Transforming a network into a distributed cloud The idea behind NFV/SDN is that this new technology enables telecoms businesses to transform network nodes into micro data centers, which can host not only the software implemented network function (Virtualized Function), but also customer applications. In this way, the network can be transformed into a distributed platform that can re-shape itself dynamically to better service customer applications and allocate its resources according to customer application needs. In particular this paves the way for edge computing, which is a function for low latency networks need for Internet of Things (IoT) applications. For customers, this means a better experience and the potential to utilize a new type of services in the IoT domain, which require the applications to be placed at the edge of the network.

This intelligence requires an end to end view of the virtualized and non-virtualized networks. The Comarch approach is to employ virtualized OSS functions to implement NFV MANO and augment the functionality of the SDN controller: NFV Management and Orchestration OSS/BSS Os-Ma OSS - traditional role Service, VNF and Infrastructure Description Se-Ma Orchestrator EMS 1 EMS 2 EMS 3 Or-Vnfm Real-time OSS - part of NVFI Real-time OSS - part of NVFI VNF 1 VNF 2 VNF 3 Ve-Vnfm VNF Manager(s) Or-Vi NFV 1 Virtual Computing Virtual Storage Vn-Nf Virtualisation Layer Virtual OSS for SDN Nf-Vi Vi-Vnfm Virtualised Infrastructure Manager(s) VI-Ha Computing Hardware Storage Hardware Hardware Execution reference points Other reference points Main NFV reference points OSS role on top of ETSI reference architecture Application Layer Controller Layer OSS / BSS Product, customer 360 view Service Service Service (Customer) Service e2e view e2e view Big Data Controller framework Infrastructure layer - Controlled by Open Flow (Open flow) (Open flow) (Open flow) API (Open flow) SDN architecture the role of OSS

4 BENEFITS Implement multi-domain, virtualized and non virtualized management and orchestration n Avoid introducing a new silo : NFV/SDN Comarch OSS can play the traditional umbrella role and, at the same time, is part of the SDN controller and NFV MANO (Management and Orchestration) n Manage both the legacy network and the virtualized one to avoid the problematic transition period, and calculate customer impact for SDN, NFV and the traditional network simultaneously n Manage services based both on physical and virtualized network functions Implement a customer service driven, end to end based automation n Benefit from both a network and a customer service view for the SDN controller and MANO, and easily implement the network as customer service/application driven cloud vision n Automate unlimited SDN and NFV MANO to a virtualized domain by using the full end to end view provided by OSS and BSS n Rapidly introduce the services based on virtualized and physical network functions Shorten the time to market n Shorten the time to market for new services managing all abstraction layers: control the commercial aspects of services as well as high level and low level design, including the virtualized and non-virtualized network functions needed to implement customer services n Trigger service chaining and related Function orchestration thanks to the customer service order driven by the service catalog model n Align customer services with low level network orchestration thanks to consistency based on the TMF SID model (CFS-> RFS->R -> Virtual Functions -> Virtual Machines -> physical machines) Achieve consistency of low level management with high level network and service management n Avoid synchronizing the network view between OSS and NFV/SDN infrastructure, as Comarch OSS is part of NFV/SDN n Make network planning visible to the SDN controller and NFV the network is controlled by what has been planned and what the customer orders

5 BUILT-IN MODULES: n Inventory provides the physical topology of the network and chooses the best matches for virtual machine and network functions. Data plane topology is fed to the SDN controller, which is crucial for effective virtualized and non-virtualized network function chaining n Service Inventory provides the service chaining view of the network n Next Generation Service Fulfillment and catalog driven orchestration are both essential for implementing service chaining and service delivery to customers, based on the virtualized and non-virtualized parts of the network n Next Generation Service Assurance helps in understanding of the impact of physical hardware failures on VMs, VNFs, service chains and, ultimately, the customer, and to automate the process of resolving problems n Performance Management (PM) and Service Quality Management (SQM) monitor virtualized and non-virtualized network function performance and enable SDN controllers to redefine network connectivity automatically, thus providing the best possible customer experience at peak load times
