Using GIS To Support Advanced Services Operations Systems for Broadband Networks
Defining Issue: Advanced Services Operations Systems (ASOS) is an Integrated Product Offering (IPO) from Lucent Technologies that provides advanced operations support to hybrid fiber-coax (HFC) broadband networks. Performing various high-performance onl-ine operations based on the locations of network elements, alarms, and field technicians in reference to street networks, city boundaries, wire center boundaries, and so forth, in a distributed client/server computing environment while allowing constant update to the spatial database can be a very challenging task.GIS Solution: The Lucent Technologies Work Management Product Team has developed a GIS-based application server module called Geographic Information Systems Data Manager (GISDM) that supports all GIS functionalities of ASOS.Methodology: GISDM maintains a number of geographic data layers in a GIS database (GISDB) that are updated daily through a cron-controlled ftp link to an external GIS data server that provides new or updated data to GISDM
in an agreed upon format. On top of GISDB, GISDM supports various high-performance on-line queries from other application modules and the GUI workstations. For example, it can generate an approximate street address or find a parcel number from a given coordinate pair to support physical network database update. It can also retrieve the bounding box of a polygon feature or street for the GUI workstation to zoom to the identified feature. The geocoding server can retrieve an approximate coordinate pair and/or a bounding box from a full or partial address even if the street names and/or city names are misspelled.Software: ASOS/GISDM is developed to run under HP-UX. The majority of the data of DGISDB are stored in an ArcStorm database. The reference data that support geocoding are stored in MatchWare format as UNIX files. The ASOS/GISDM application is written primarily in AML and C++. The libraries used include Esri's IAC and ArcSdl, MatchWare/CL, USL C++ Standard Components, as well as other
libraries developed within Lucent to support tracing, error logging, and intermodule communications. The purpose of this paper is to highlight the functionalities of the application and the high level architecture of the system. The technical challenges in implementing and integrating different third party software products into an ASOS component application that meets the high-performance requirements will also be reviewed.
