1 Lifecycle Service Manager NetACE White Paper

2 SDN Migration and Deployment Challenges SDN holds great promise in terms of simplifying network deployment and operation along with lowering the total cost of managing enterprise and carrier networks by providing programmable network services. However, a number of challenges remain to be addressed: Preserving the effectiveness of network operations during the transition state It would be straightforward to deploy a completely new infrastructure based on SDN technology. For this, all elements and devices in the network would be SDNenabled. However, there exists an installed-base of networks today that cannot be replaced in one day or in the near future. The transition to SDN requires simultaneous support of SDN and traditional equipment. Further development and complicated integration is required to achieve a hybrid SDN infrastructure in which traditional, SDN-enabled and hybrid network nodes can operate in harmony and being managed and automated at the same time. Such approach would reduce the cost, risk and disruption for enterprise and carrier networks transitioning to SDN as well as enable new revenue generation and SDN-like programmability during the transition state, which is an extremely painful process for the operator in terms of operational efficiency and expenses. Applications compatibility issues An SDN Controller communicates with SDN Applications, these applications are written to a set of APIs that are provided by the SDN controller. Generally, APIs are not standardized, so an SDN Application that runs on a given SDN controller may have to be modified to run on another SDN controller. A Mediation Layer for connecting network Applications to re-configurable Network Nodes / SDN controllers is required. Missing Skills SDN requires bringing together advanced networking and programming skills, which is not a common thing among IT professionals, especially in an environment where the staff is constantly replaced by new ones. Conclusion SDN offers many advantages to network design including programmability, agility and NFV. However, in most cases SDN is not being deployed in greenfield networks. To ensure the smooth and cost-effective transition to SDN (and afterwards) without disrupting daily network operations and revenue streams, an operator requires a set of SW tools like those described in this paper to streamline the management of a complex multi-vendor network built of different generations of telecommunication equipment and to deliver open and unified programmable interfaces to allow the orchestration of applications and automation of network functions. NetACE SDN Lifecycle Service Manager 2

3 NetACE Value NetACE is designed to transform enterprise and carrier networks by unifying traditional network management and open, SDN-style network orchestration and programmability to enable Lifecycle Service automation and flexibility, being a missing link in the transformation from Legacy to Next Generation networks. NetACE shortens service delivery times and reduces operational expenses by simplifying and automating service design, service activation, network-aware resource allocation and routine network maintenance tasks across multi-vendor, multi-service networks of different generations. NetACE provides control, e2e visibility and real-time assurance over the customer s network and services through a single pane-of-glass management.

Atrinet has developed a simple and intuitive process of designing new services in NetACE using the web-based Service Modeling Tool without the necessity for any programming skills and system upgrades. Programmable Networks that allow business customers and/or their applications to order, add, change and flex connectivity services on demand are variously called "programmable networks," "user-defined networks" or "network as a service" (NaaS), but the principle is the same. They allow customers, through a portal, to logically define where they want connectivity services, their type and bandwidth. NetACE receives the service creation request and user parameters through its programmatic interfaces and automatically provisions the service, taking minutes to deploy what would once have taken a team of network engineers perhaps weeks to roll out..

9 NetACE Applications NetACE Web-based ing Tool and Service Catalog Manager NetACE's Open Model-driven Service Design Architecture enables the design of the most complex service types and run-time introduction of these completely new services to the Service Catalog in a matter of hours. Atrinet has developed a simple and intuitive process of designing a new service in NetACE using the webbased ing Tool and Service Catalog Manager that operates in a "drag-&-drop" manner. This web-based tool facilitates the addition of new service models that are automatically saved to the Service Catalog as well as modification of existing ones. Users model a service based on their knowledge of the network and the service type they wish to implement, sometimes even relying on pre-existing Network Entities that contain the set of CLI commands currently used to deploy a service. A service model can be defined using either the rapid point-and-click Service Creation GUI or a scripting language or a mixture of both. This flexibility allows the design of a variety of models ranging from the simple service model containing a set of commands and parameters to the complicated ones which can include command conditionals, sophisticated network logic and parameters requiring validation by built-in, user-defined Resource Managers.

10 NetACE Multi-vendor Topology Discovery Engine (and GUI) Provides an accurate view of your network by automatically discovering and tracking changes to your network s equipment. NetACE s automated discovery process completely eliminates preparatory manual data entry. Adding a new Vendor in 15 minutes (via GUI) Adding a new and previously unknown device vendor to an NMS is usually a very expensive and time-consuming process which requires vendor intervention and extensive development effort. The device may have non-standard MIBs that need to be mapped to the device properties, and therefore the relevant changes must be inserted in several places in the source code (e.g. OIDs must be hardcoded to show module information). These code changes inevitably mean the release of a new software version. With NetACE's new Custom Device feature, adding a new device type is speedily done within 15 minutes and never requires code modification. As part of the process, every new device type configuration is automatically stored into NetACE's database including all its OIDs as configured by the operator. Modification of the mapping between the device's MIBs and of the full set of properties controlled by NetACE is simply achieved via GUI-based Device Type Manager and in effect allows any device vendor to be automatically discovered, have a full set of managed properties, FCAPS and automated Service Lifecycle capabilities.

Rapidly design, configure, activate, plan and allocate resources, discover, assure, control all types of customdesigned services over a complex multi-vendor network. 15 minutes To model a new device type Control Design Configure 2 hours To model a new service Assure NetACE Service Lifecycle Activate 1 minute To activate a new service Discover Allocate resources NetACE SDN Lifecycle Service Manager 11

12 NetACE Real-Time Service Discovery Engine Discovery and reconciliation of services and network resources are key components of Lifecycle Service Management, efficient network utilization and stability. NetACE enables operators to discover and manage not only all cross-silo services created via NetACE but also has a unique technique to discover externally created brownfield services. NetACE Zero-touch Service Provisioning and Planning NetACE eliminates the complexity of circuit provisioning though zero-touch automated service activation for L2-L4 services. It enables pre-provisioning of services prior to deployment of physical network elements, automatic resource allocation and ensures that the configuration parameters necessary for service delivery are correctly applied. NetACE RESTful APIs NetACE provides robust northbound RESTful APIs for automated network provisioning, customer management, billing, payment and ordering functionality, and integrates with the latest web technologies and OSS/BSS systems. NetACE User-defined Resource Management and Automated Resource Allocation NetACE, with its user-defined, network-aware Resource Management and Automated Resource Allocation system, reduces the need for administrators to be constantly engaged in endlessly repetitive routine work, allowing them to focus on the broader, higher-level tasks of managing their infrastructure. Sophisticated and custom-defined resource management and automated resource allocation system helps to avoid human errors while maintaining multiple customer datasheets outside the system and attempting to set the correct parameter during provisioning. It replaces the manual, error-prone and timeconsuming resource lookup procedures with a smart and fully automated resource allocation process which is custom-defined and managed inside the NetACE s database.
