Fixed Line Planning - Click to Enlarge

Today service providers are faced with the task of managing a mix of technologies while executing a strategy of migrating services to new network infrastructure.

Planning and optimizing SDH/SONET networks has become an exercise in reducing capital expenditure while still supporting high-value services in a hybrid, multi-technology network.

IP, MPLS and Ethernet network planning benefits from the inherent flexibility of these technologies, but must concern itself with the complexities of delivering reliable classes of service to customers.

Optical rollout continues to expand the capacity of core network connections, and is increasingly being used in the transport and access domain. Planning of data and SDH/SONET services has a direct impact on optimisation of the optical layer, and good design of the optical layer is necessary to ensure quality of service in the data and TDM layers.

Aria Networks provides the solution to communication service providers needs for planning multi-technology core and transport networks. Aria ensures return on investment in assets is maximized while offering predictability for service evolution on next generation networks. Aria’s unique multi-layer planning is able to optimise connections and services while considering the impact on all the service provider’s networks.

Service providers’ networks comprise a number of different traffic technologies. These have a variety of dependencies on each other. Optical networks carry SDH/SONET and packet data payloads. SDH/SONET may carry packet data, or label switched paths may carry SDH/SONET payloads. This flexibility, while beneficial, requires more planning to efficiently use resources and ensure quality of service.

Aria is able to plan across all layers, considering service requirements and cost. This accelerates planning cycles traditionally split between several teams, and allows the operator to balance services demands across underlying transport resources.

Capacity Planning

Telecommunication networks grow and evolve. Whether the industry is going through a feast or famine of capital expenditure there is a need to understand where investment in assets is required and where upgrades will generate a return.

Aria offers comprehensive insight in to the impact of growth on existing resources and identifies where new assets must be deployed in the network. Communication service providers are able to see how planned services consume resources such as VLANs, devices, cards, and ports, and generate optimal bill-of-materials for just-in-time network upgrades or long-term architectural changes.

Maximising Asset Utilisation with Worst Case Failure Analysis

Maintaining reliable, resilient network architectures is critical for ensuring continuity of service and avoiding SLA breeches. Without detailed analysis service providers may simply rely on rules-of-thumb to avoid overbooking paths across the network or to build out redundant equipment and paths. The result is unnecessary, costly contingency built in to network plans and the subsequent CAPEX.

Aria Networks analyses networks using worst case failure analysis to determine just how resilient networks are to one or more points of failure. By systematically analysing failure states and service re-routing Aria can determine how assets should be used to minimise cost while maintaining your required levels of resiliency.
