NFV/SDN

If providing innovative services and a seamless digital experience give your company its competitive edge, don’t let rising operational costs or network limitations impede your ability to shine among CSPs and OTT players. Software defined networking (SDN) and network 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. With an SDN and NFV solution, operators can lower their costs, unleash service innovations and better respond to their customers’ needs.

Comarch NFV/SDN-enhanced OSS solution provides a consistent platform that can be used for the provisioning and management of services over VNFs and PNFs, legacy and SDN-enabled network cross-sections. A software-defined networking solution allows an end to end view of the network and facilitates a model-driven approach, thanks to which telecommunications service providers are able to reduce time to market and costs for customer services built on a hybrid network.

OSS for SDN NFV Orchestration - Benefits of the Comarch Solution 

True e2e service orchestration

To deliver dynamic NFV-based services to their customers, CSPs need to combine NFV orchestration with fulfilment over their existing physical networks. Comarch Next Generation Service Orchestration, not only includes NFV orchestration, but is also a level above MANO architecture and enables end to end service fulfilment over both legacy and SDN/NFV-enabled networks.

Shorten time to market

Telcos need to shorten the cycles for bringing new services to the market. SDN and NFV are the key enablers for this. But to be used effectively, SDN and NFV need to be complemented by an efficient management stack capable of dealing with all abstraction layers, from product and service, through PNFs and VIM-neutral VNFs, all the way to NFVI resources and the network infrastructure required to implement customer services.

Consistent tools for managing hybrid networks

With the introduction of MANO and SDN controllers, service providers neeed to integrate them with their existing OSS or run the risk of creating new silos. The Comarch solution addresses this issue by driving consistency throughout the solution. Comarch modules can play the traditional OSS role and, at the same time, are part of the SDN controller and NFV MANO helping telecom operators smooth the network transition.

Model-driven provisioning and automation

Operators need a scalable approach for managing expanding service and network complexity. Employing a model-driven approach permits service providers to manage that complexity and maintain control throughout service lifecycle. Comarch employs a model-based approach throughout its OSS solution, supporting catalog-driven service orchestration, vendor-agnostic configuration management and automated service assurance use cases.

SDN/NFV - Comarch Solution Features

Next Generation Service Orchestration

A catalog-driven orchestration platform that enables simplified yet powerful end to end service delivery to customers, over the virtualized and non-virtualized parts of the network.

  • Based on the TM Forum SID model (CFS-RFS-R).
  • Supports service decomposition, free-style combining and orchestration.
  • ETSI NFVO extended with support for PNFs, multi-domain orchestration and manual tasks.
  • Support for dynamic service chaining and service lifecycle management.

Integrated VNF and PNF Management

Comarch offers a model-driven resource management portfolio with integrated support for VNFs and PNFs, allowing gradual evolution towards NFV.

  • Single integrated resource catalog and inventory that can manage VNFs, PNFs and NFVI resources or delegate parts of the model to a lower level system.
  • Generic VNF manager implementation for handling VNF lifecycle, including VNF scaling and healing.
  • VNF onboarding through ETSI-compliant descriptors. VNF customization through Comarch Console GUI.
  • OpenStack integration.

SDN

Consistent SDN and legacy network management, thanks to intelligent automation algorithms and open source SDN mediation combined with the proven functionality of Comarch Configuration Management module. 

  • Deep integration of OSS components into OpenDaylight SDN controller. Support for OpenFlow and SDN in IP/MPLS networks (PCEP, BGP-LS).
  • Solution can act directly as an SDN controller for some domains, and cooperate with a third-party domain controller for others.
  • Comarch Configuration Management module for vendor-agnostic, model-driven network reconfiguration supporting a wide range of network technologies and devices.
  • Simultaneous support for VPNs and VNFs in a single system (Comarch OSS) provides the foundation for network slicing.

Fault, Performance and Service Quality Management for SDN/NFV

Next Generation Service Assurance monitors the impact of physical hardware failures on VMs, VNFs and, ultimately, the customer, and automates the process of resolving problems.

  • Fault and KPI monitoring for OpenStack and OpenDaylight. CCorrelation of VNF and NFVI resource alarms and KPIs.
  • Comarch Fault, Performance and Service Quality Management monitor virtualized and non-virtualized network functions, triggering VNF healing and scaling to provide the best possible customer experience at peak load times.
