  1. Sprint’sEarly Interest inTINA-C

  2. Introduction • Sprint had a number of projects during the 1991 through 1994 time-period aimed at unifying the architecture used to build computer systems. • Drivers • Cost of duplication of data and functions in computer systems • Development for each product or service • Multiple order entry systems - voice and each data product (X-25, FR, IP, ATM) • Cost of maintaining interfaces between systems • As services become more complex, interface maintenance is significant drain on resources • Ability to manage multiple services over ATM • Frame Relay over ATM, IP over ATM, Voice over ATM, Voice using ATM • Fault Management needs to be able to correlate alarms from all network elements • Separate systems for each element type require manual interpretation of alarms • Need for very fast service (product) development • First to market gets a disproportionately large share of sales • Focus - 2 main categories • Technical architecture - how systems are built • Functional architecture - grouping like functions - build each process once • Data architecture depends on these being defined first

  3. Functional Architecture • My involvement has been with the functional architecture for which there are a number of names: • Enterprise Total Computing - ETC • My preference - its scope is all functions except Human Resources and Stockholder Services • Integrated Service Management - ISM • Used by Sprint associates since 1993 - we were unaware of the GE-Bull product, ISM. • Misleading as many think it only includes network and element management. • Communications Business Model - CBM • Used by those Sprint developers responsible for including new developments from both TINA and Telemanagement Forum. • 2 Primary Approaches • Top down - business developers saw many functions that used a single network • Bottom up - the traditional TMN pyramid, heavy at element level and ignoring business complexity • Merged Functional Architecture - ISM - December 1994

  4. Components • Standards based whenever possible • Industry standards for common objects • Open systems interfaces • Electronic bonding for network management interfaces • Functional Architecture • Grouping of processes by function to simplify reuse of common procedures • Will be replaced by an Object Architecture when analysis and design are sufficient • Data Architecture • Enterprise Object Model developed and being tested and improved • Program View - grouping of functions for re-engineering by: • Service Creation • Service Delivery • Service Assurance • Billing • Asset Management • Planning

  6. The TINA Discovery • A Sprint colleague met Hendrik Berndt in 1994 or 1995 • Have you looked at TINA? • We looked at TINA • Many man years of expert work was available for us to improve ETC • The documentation included the reasons for decisions: • Why items were in or out • What was need to complete them (e.g. IDL --> ODL) • Many of our conclusions were reinforced • Most of it made sense • We discussed a few problems with Hendrik who was often in KC • Many carriers with whom we interface were TINA-C members • Using TINA would help when developing future interfaces • Our enterprise object model incorporated TINA concepts • We made some changes to our functional architecture
