Architecture Diagrams

This page uses simple text diagrams so the architecture remains readable in Git and in the docs site without extra rendering plugins.

System overview​

Users
  |
  +--> intt-portal (Angular web)
  |
  +--> intt-mobile (Flutter app)
          |
          v
    Core and domain APIs
      - authentication-service
      - setting-service
      - data-service
      - ticket-service
      - gsb-service
      - ngoss-service
      - nocgrid-service
      - nocpro-service
      - tmf-service
      - vital-service
          |
          v
    Shared infrastructure
      - MariaDB
      - Redis
      - RabbitMQ
          |
          v
    Async workers and external systems
      - caution-report queue
      - ctt queue
      - gsb queue
      - changedp vendor queues
      - kci queue
      - tass queue
      - vital queue
      - APIM / TMFORCE / NIG / vendor endpoints

Auth and login flow​

Browser
  -> intt-portal
  -> OIDC / SSO redirect
  -> callback in intt-portal
  -> auth/login API call
  -> mvp1-authentication-service
  -> token exchange and user context lookup
  -> portal stores app tokens and user profile
  -> portal loads shell and feature modules

Web request flow​

Example: a user opens a ticket-related page in the web portal.

Browser
  -> intt-portal
  -> CoreAPIService selects backend base URL
  -> Authorization header added by interceptor
  -> mvp3-ticket-service
  -> MariaDB / Redis / supporting modules
  -> JSON response
  -> intt-portal renders list, detail, or dashboard state

Async queue flow​

Example: GSB or vendor-command flow.

Portal or mobile
  -> mvp3-gsb-service
  -> RabbitMQ publish
      - intt_gsb_queue
      - intt_alu_queue
      - intt_zte_queue
      - intt_fiberhome_queue
      - intt_huawei_queue
  -> queue worker consumes message
      - gsb-queue-service
      - changedp-queue-service
  -> external network or APIM integration
  -> result persisted or logged
  -> downstream status available to API and UI
