NDAPT

The NDAPT is most comprehensive, network dimensioning analysis and planning tool in the telecom market. The Core Network Dimensioning Analysis and Planning Tool (NDAPT) system, offers a complete solution for all stages of core network design and analysis.

Managing a telecommunication network is a challenge requiring careful balance. Operators must continue to maximize the network's capacity and service revenues while minimizing network investments. They must also consider the increasing economic and social forces pres­suring for an improved grade of service (GOS). The NDAPT helps you to produce the design and dimensioning of a circuit switched (CS) core network for GSM/VAS, and UMTS including SS7/SIGTRAN. Design rules like network Grade of Service (GoS) and minimizing infrastructure costs of the network are the constraints for NDAPT.
Traffic, as it is applied to telecommunications, is an in­tegral part of this balance. The network's grade of service, quantity of equipment, revenues and expenses are all dependant on traffic flow and its efficiency.

Network Modeling and Planning Tasks
Automatically generates latest network picture from network or any 3rd party PM tool as well as TTG’S NORTH-I PM tool where all PM statistic and prediction module available on the NDAPT. System also collects routing table (with MML,TL1, etc…), alternatives, load sharing, and etc…from the network daily or any given time.
Modeling of circuit switched core network topologies with all relevant nodes such as switches (MSCs, GW-MSCs), Point of Intercon­nections (POI) to PSTN and other PLMN, Application Server, SMS, Voice Mail Centre etc.

• Definition of subscriber traffic models for the different applica­tions and network areas
• Modeling of source/sink traffic relations (traffic matrix) for all individual network nodes and sup­ported applications; these traffic relations can be derived from a runningnetwork or can before­casted traffic.

Calculation of routing plans under different constraints, for example, in order to minimize connection costs for leased lines and minimizing transit costs for calls to PSTN.

Analysis of given routing plans discover routing loops and auto­matically resolve them.

Dimensioning for changed traffic conditions and changed network topology, for example, introduc­tion/retirement of switches, con­nections and links
Analysis of different network topologies, for example, com­paring meshed topologies with hierarchical network structures (determination of routing plans, costs, etc.)
Some other functions

• Determination/optimization of the Rout and Signaling Network Structure
• Determination of an optimized design of the routing data of each signaling point (Routing of Signaling Traffic)
• Dimensioning of the signaling link Set under consideration of network failures (failed route sets and Signaling points)
• Determination of Signaling Network Performance

Accurately Model PM data “As-Running” Network

NDAPT “what-if” analysis features let engineers accurately model changes on the “as running” network, using the actual routed topology at the current time or from any point in the past. Engineers can simulate a broad range of changes, such as adding or failing routers. Critical initiatives such as data center migrations/consolidations, disaster recovery planning, change validation testing, or failure impact and redundancy analysis can be easily and accurately performed.

• Different network scenarios simulations

On line and Historical data movies
NDAPT can access both current and historical network data from NORTH-I or any 3rd party PM tool. The normal use of current data is to display the operational status of your network from hour to hour and day to day. Historical data is useful for displaying trends in performance, and for examining significant past events in the network. When you request historical data from NDAPT, it interrogates NORTH-I for the relevant data and stores it. You can then view this data using NDAPT’s movie tool. This offers controls similar to a video recorder, and allows you to ‘play’ the retrieved historical data in a view in accelerated time. It has controls that allow you to play, pause, stop, and fast-forward or ‘rewind’ the historical data, play it in reverse or frame-by-frame.

NDAPT Benefits
· Update network Picture
· Comprehensive view of end-to-end traffic flows over every link enables network-wide congestion detection, capacity planning and traffic analyses
· Fast and effective new network design
· Maximizes network availability and customer satisfaction by rapidly identifying and diagnosing
· Reduces total operating cost by improving productivity of both network resources and network engineering staff.
· Validates desired network operation after maintenance activities, helping to avert router missing or wrong configurations that cause one third of all network problems.
· Reduces “finger-pointing” often associated with difficult-to-diagnose network problems, while minimizing demands on scarce engineering resources.
· Enables network engineers to predict routing problems and take action before they occur.
· Verifies and alerts on changes to routing redundancy, preventing costly service outages.
· On-line modeling using actual network topology and traffic loads helps avoid unnecessary link upgrades, maximizes asset utilization and enables accurate network planning and optimization


Predict and Plan for Network-wide Capacity Requirements

NDAPTgives network managers the information they need to accurately predict and plan for future capacity needs across their entire network. Engineers can view and analyze historical traffic trends by volume or utilization, including breakdowns by application and Class of Service on every link in the network, as well as by exit router.

Going well beyond the typical link-based traffic statistics provided by other tools, NDAPT lets engineers analyze and manipulate a network-wide traffic matrix, showing traffic volumes between every source/destination pair in the network. Detailed capacity projections can be accomplished by exporting the full traffic matrix to a spreadsheet, adjusting any source/destination traffic volume based on internal initiatives or forecasted loads, and then importing the updated matrix to see the impact on network-wide link utilizations. New application deployments can be accurately “tested” on the as-running network, before they are deployed, by adding expected traffic loads to existing traffic volumes, and viewing the resulting traffic load on every link. Engineers can quickly identify potential hot spots by application or Class of Service, and determine whether traffic can be re-routed around the congested links, saving unnecessary bandwidth upgrades, or whether additional capacity is required.
