Event Subsystem

AdvantEDGE provides a built-in Event Subsystem that integrates with scenarios.

This feature provides the following capabilities:

• Network mobility event
  • Change the network location of a physical node in the network topology; this feature emulates mobility of connected devices.
• Network characteristics event
  • Change the configured network characteristics of a scenario node; this features emulates changing network conditions, for example if suddenly latency increases, bandwidth reduces, error rate increases
• Compute event
  • Creation/deletion of process scenario nodes; this feature emulates changing compute environment where new edge services or terminal applications can be started at scenario runtime.
• PDU connectivity event
  • When executing a scenario in PDU connectivity mode, allows creation/deletion of PDU sessions to target Data Networks; this feature allows to emulate certain behaviors of mobile networks.

Following any of the above events, network charactreristics of all affected nodes are re-calculated and re-applied.

  • Mobility events: UE connects to PoA according to PoA Selection algorithm
  • UE movement: UE follows defined path according to speed & EOP action
  • PoA in-range events: generates event listing all PoA in range
  • Network Characteristic update events: drive network characteristics based on distance from PoA (v1.6+)
  • Provides a more complete emulation for Location, RNI & WAI services

Monitoring Subsystem

AdvantEDGE provides a built-in Monitoring Subsystem that integrates with scenarios.

This feature provides the following capabilities:

• Scenario local measurements
  • Automated Network Characteristics: Latency, UL/DL throughput, UL/DL packet loss are automatically recorded
  • Automated Events: Scenario events generated towards the Events API are recorded; recorded events can originate from the frontend, from an external source, from a replay file or from one of the automation.
• Custom measurements
  • Custom metrics: InfluxDB API is available for logging your own time-series metrics; just need to include an InfluxDB client in your application and start logging.
• Dashboard visualization and management interface
  • Built-in network characteristics dashboards: visualize point-to-point (source to dest.) or aggregated (source to all) network metrics
  • Built-in wireless metrics dashboards: visualize wireless metric KPIs (RSRP, RSRQ, RSSI & PoA distance)
  • Custom dashboards: create your own dashboards; allows access to display automated measurements (net.char/events) with your own measurements.
• Metrics API
  • Expose metrics to applications: Metrics can be exposed to external applications for conducting network adaptive experiments.
• Platform metrics local monitoring
  • Automated Platform Micro-Services monitoring: Prometheus collects metrics locally about the platform micro-services; this allows AdvantEDGE platform usage metrics in your deployments.
• Metrics Long-term Storage (Optional)
  • Long-term data retention: Thanos pushes Prometheus metrics to object store every 2 hours
  • Daily backups: cronjob pushes InfluxDB data to object store

Sandbox Subsystem

AdvantEDGE provides a built-in Sandbox Subsystem that allows to share the platform with multiple friendly users.

This feature provides the following capabilities:

• Sandbox management
  • Create/Delete sandboxes
  • Manage sandbox data
• Scenario isolation
  • Execute/monitor/terminate scenarios in an isolated manner
• Collaboration
  • Allows multiple users to observe the same sandbox

External Node Support

AdvantEDGE supports experimenting with applications and services that run on nodes external to the platform.

This feature provides the following capabilities:

• External UE integration
  • Network Characteristics: network characteristics are applied to ingress/egress flows from/to the external device
  • Events: scenario events impacts network characteristics from/to the external device
• External Compute nodes integration (fog/edge/cloud)
  • Network Characteristics: network characteristics are applied to ingress/egress flows from/to the external device
  • Events: scenario events impacts network characteristics from/to the external device

Pod Placement Support

When deploying on a multi-node cluster, AdvantEDGE supports pod placement on specific nodes.

This feature provides the following capabilities:

• Override Kubernetes placement
  • This may be useful when the cluster nodes have specific hardware characteristics
  • Ex: Applications may require specific hardware (GPU, CPU, etc.) available on a single node only
  • Ex: Scenarios with several client/server applications may require specific node placement in order to minimize network traffic between k8s nodes

Process Lifecycle

AdvantEDGE supports dynamic addition and removal of terminal, edge or cloud applications at scenario runtime. This Process Lifecycle management feature enables a new set of platform experiments.

NOTE: The terms process & application are equivalent and used interchangeably in this document.

This feature provides the following capabilities:

• API to trigger active scenario updates
  • Allows to create and delete terminal, edge & cloud applications
  • Validates process fields before updating active scenario

Cellular Connectivity Control

AdvantEDGE supports a cellular connectivity control emulation mode that mimics networks that require Packet Data Unit (PDU) session establishment to data networks.

This feature provides the following capabilities:

• Connectivity emulation model
  • Scenario can emulate OPEN or PDU connectivity model
    • OPEN: (default/legacy mode) terminal can consume services from any compute node in the model
    • PDU: terminal must establish a PDU session to a Data Network Name (DNN) consuming any services from that DNN
• Data Network (DN) emulation
  • Compute nodes (edge/fog/cloud) can be assigned a Data Network Name (DNN)
    • DNN can be shared with many compute nodes
  • Terminal can reach DNN from anywhere in the network (as long a PDU session is established to that DNN)
• Local Area Data Network (LADN) emulation
  • Same as DN, but only accessible when the terminal is in the same area (e.g. zone) as the LADN
• Edge Computing Service Provider (ECSP) emulation
  • Compute nodes (edge/fog/cloud) can be assigned an ECSP name
  • Currently unused
• API to trigger PDU session management
  • Allows to create and delete PDU sessions
