Overview
Overview Heterogeneous

  • ADL-based architectural modeling – C2SADEL

    • explicit components and connectors

    • stylistic constraints

    • message-based interaction

  • Tool-supported architectural analysis – SAAGE, UML/Analyzer,and AAA

    • topological constraints

    • component interfaces and behaviors

    • non-functional properties

    • refinement into design

    • implementation generation

  • Infrastructure for architectural prototyping, implementation, execution, and runtime manipulation


Flexible gauge placement and visualization

Allow dynamic, automated or Heterogeneoususer-initiated gauge placementand architecture visualization.

Goal

Treat gauges as first-classarchitectural entities that can beinserted at arbitrary locationsand times in an architecture.

Method

Light-weight, flexible, extensiblearchitecture prototyping and/or implementation infrastructure.

Explicit treatment of components,connectors, ports, events...

Hierarchical application ofarchitectural concepts on complexcomponents and connectors.

Gauges in action integrating ots components
Gauges in Action: HeterogeneousIntegrating OTS Components

  • Gauges to measure functional suitability of a partially modeled component to an architecture

  • interface match

  • behavior match

  • interaction match

Partial Architecture

OTS Component Library


Gauges in Action: HeterogeneousReliable Upgrade of Components

  • Gauges to measure different aspects of new component versions:

    • correctness

    • performance

    • robustness

    • reliability

  • of the new version w.r.t. the old version


Gauges in action ensuring consistency among heterogeneous semantic models
Gauges in Action: HeterogeneousEnsuring Consistency among Heterogeneous Semantic Models

  • Component

    • Static modeling (e.g., invariants and pre-/post-conditions)

    • Dynamic modeling(e.g., statecharts or CSP)


Gauges in action measuring shared properties of heterogeneous connectors
Gauges in Action: HeterogeneousMeasuring Shared Properties of Heterogeneous Connectors

  • Properties of connectors influence the properties of large, distributed systems

    • Throughput

    • Load

    • Security

    • Reliability

    • Performance


Technologies implementation infrastructure
Technologies: HeterogeneousImplementation Infrastructure

Lightweight and extensible

  • Supports explicit components and connectors

  • Aids transition between architecture and its implementation

  • Allows arbitrary insertion of gauges to monitor different aspects of an application at runtime

  • Version for embedded devices – extremely lightweight, supports distributed applications, multiple address spaces


Mapping from c2sadel to uml
Mapping Heterogeneousfrom C2SADEL to UML

Goal:Couple UML with ADLs to EnableRound-Trip Architecture-Based Software Engineering


Technologies saage

Schedule

Impact

  • Reliable upgrading of software components (without losing the functionality of the old version)

  • Assessing suitability of COTS components to the given system

  • Identifying mismatches before the system is built and deployed will save both time and effort in the long run

  • Properties of connectors influence the properties of large, distributed systems

  • (1,2,3) Gauges to measure the functional suitability of a partially modeled component to an architecture

  • (4) Gauges for determining design- and integration-time development risks based on the non-functional properties of interacting components

  • (5) Gauges to measure the consistency between heterogeneous semantic models of a component

  • (6,7,8) Gauges to measure different aspects of new component versions

  • (9,10,11,12) Gauges for measuring shared properties of heterogeneous connectors
