The AccessPlan software is a framework developed by us for automated design and evaluation of next generation access networks. It provides topology design, optimization, cost estimation and techno-economic evaluation/comparison for various fully or partly optical technologies (xPON, xDSL, Active Ethernet of Point-to-Point optical access).
The framework is also used to test and validate methodology and algorithms against real-world problems and scenarios. Our existing and new ideas appear primarily in the AccessPlan tool, for research purposes, and supports our scientific publications.
.
Development of the framework was lead by Attila Mitcsenkov, with various contributions from our students over the past years. The supporting research leading to the methodology was the main body of Attila’s PhD, and strongly supported by his supervisors, Géza Paksy and Tibor Cinkler. The software itself is developed in C++, heavily using the LEMON Graph Library, integrating ILP solvers CPLEX and/or GLPK.
.
The AccessPlan Framework provides the following functional layers:
.
Deployment cost calculations & Techno-economic evaluation:
  • Detailed cost models (incl. cable plant installation and fiber costs, network equipment)
  • Deployment cost (CAPEX) calculations & long term cost evolution considered
  • Feasibility studies
  • Comparison of various network architectures and technologies
  • Decision support for choosing the best economical/technical solution
Topology Optimization:
  • Optimization with highly specialized and effective heuristics
  • Strategic System Design (cable and fiber plant layout, network equipment locations, subscribers groups per splitter/switch)
  • Fully automated algorithmic solution, with a wide set of control features
  • Provides detailed network data as input for highly accurate deployment cost (CAPEX) estimations
Network modelling and calculations
  • Main focus on effective and fast algorithmic operation
  • Allows handling of large scale problem instances (10.000+ nodes)
  • Provides in-depth statistics of the subscribers, locations, street system, etc.
GIS (map) data processing, as input of the topology design process:
  • Various map formats, including publicly available OpenStreetMap XML
  • Existing infrastructure (cable ducts, exinsting network elements, etc.) considered
  • Subscriber/household data integration from various sources
