OSS Design Patterns —A Workshop on the Design of NGOSS Interfaces
CalendarUpcoming Training Schedule



The TM Forum’s Solutions Frameworks (NGOSS) help address the challenges of managing telecommunications networks by providing a number of frameworks for the development of management applications. Complementing the Information Framework (SID), this workshop provides in-­depth study and hands‐on experience of the development of interfaces to OSS applications using a design-­pattern approach. The course is based on the authors’ book “OSS Design Patterns” published by Springer.



Instructors: Colin Ashford and Pierre Gauthier

Level  Intermediate

Who should attend? Pre-requisites
Application architects and implementers, solution architects and implementers, development managers, and network managers.
  • A general understanding of the Solution Frameworks (NGOSS)
  • Working knowledge of Java, JMS, and XML.

Technology covered:
  • The pattern content of the workshop is technology neutral, but examples will be given using Java, JMS, and Web Services.
Highlight:
  • A hands‐on introduction to OSS Design Patterns that help promote the rapid development of reliable and effective OSS solutions and substantially reduce solution costs.
Upon completion, you will be able to:
  • Understand the rationale for a pattern approach to the design of OSS interfaces
  • Understand the systems architecture development process
  • Identify non‐functional criteria for profile selection
  • Recognize situations for the appropriate use of OSS Design Patterns
  • Apply a working knowledge of OSS Design Patterns and their implementation in Java, XML, and Web Services.
Agenda (Morning Lecture):
  • Managing Telecommunications Services: the management challenge; the pattern approach; the TM Forum Business Process Framework (eTOM); the OSS Reference Model; and the OSS Systems Architecture
  • Designing Management Solutions: OSS Reference Architecture; OSS Implementation Profiles; and OSS Design Patterns
  • Key OSS Architectural Patterns: Managed-­‐entity Value Pattern; OSS Façade Pattern; OSS Event Notification Pattern; OSS Factory Pattern; OSS Discovery Pattern; examples in Java and JMS/XML; summary
  • Key OSS Programming Patterns: Managed-­entity Key Pattern; Managed-­entity Life Cycle Pattern; Managed-­entity Update Pattern; Managed-­entity Template Filter Pattern; Last Update-­Version-­Number Pattern; examples in Java and JMS/XML; summary
  • Overview of the Web Service specification
Agenda (Afternoon Lab):
  • Overview of provided code using the Net Beans Platform
  • Instructor-­led code review of OSS Design Patterns implemented using Java, XML and Web Services
  • Code review of the Simple Inventory OSS application including: entities, events, and queries expressed in Java and XML; and the implementation of the OSS Façade pattern using a session bean and a message-­driven bean
  • Instructor-­‐led development of an extension to the Simple Inventory OSS application including extending the Java interface; extending the XML schema; and implementing and testing using JEE, JAXB, and Web Services
