Automated End-to-End SLA Management of multi-vendor, multi-domain, secure , VoLTE Network Service

The Story

• Congestion caused by DDoS results decreased voice quality in Network Service as per specified KPIs - fault is detected by Service Monitoring, which raises alarm

• Faults reported from one or more Domains via E2E Integration Fabric, shared with E2E Service Orchestrator , which correlates alarms to interpret events based on metadata and metrics to classify SLA violations (may involve multiple queries for additional KPIs)

• E2E Service Orchestrator makes policy-based decisions , which trigger commands (ETSI NFV standard LCM operations) issued back to Domain(s) for remediation via E2E Integration Fabric

• End-to-End Service Orchestrator queries Domain(s) via E2E Integration Fabric for Post-action application state and network telemetry for automated closed-loop control o Re-configured and assured Network Service may result in a Billing event, based on policies , which would be reported by

End-to-End Service Orchestrator to Administrative Domain via E2E Integration Fabric



Functional Domains:

• EPC (Radisys/AWS Zone)• IMS (Metaswitch/AWS Zone)• Secure Traffic (Fortinet/AWS Zone)

Administrative Domain:

• Billing (Amdocs/On Premise) [Future Iteration]

E2E ZSM Framework-based Solution

• End-to-End Service Orchestrator (EnterpriseWeb) • E2E Integration Fabric (EnterpriseWeb)• E2E Network Service Modeling Environment (EnterpriseWeb)

o Compose Network Serviceso Define SLAs using proposed FCAPS metadata and metrics to model conditions for events and then specify

related actions (state machines) o Declare Service and Resource Monitoring Requirements as part of Service Topology



End-to-End Automation of Network and Service Management requires clear definition of Domain NBI to enable higher-level programmability

• Domain NBI exposes controls to E2E ZSM Framework-based Solution

o Network Service Ordering and Configuration

▪ End-to-End Service Orchestrator queries Domain(s) via E2E Integration Fabric and orders and configures existing Domain Network Services via exposed interface (Radisys EPC, Metaswitch IMS, Fortinet Firewall)

o Service and Resource Monitoring Ordering and Configuration

▪ End-to-End Service Orchestrator queries Domain(s) via E2E Integration Fabric and requests and configures existing Domain Monitoring Services via exposed interface (EXFO Service Monitoring probes / Infosim Resource Monitoring agents)

• Domain NBI exposes data stream to E2E ZSM Framework-based Solution

o Return state/telemetry alarms as per configuration of Monitoring Services


4.2 The Principles

Principle 01: Modularity

Principle 02: Extensibility

Principle 03: Scalability

Principle 04: Model-driven, open interfaces

Principle 05: Closed loop management automation

Principle 06: Support for stateless components

Principle 07: Design for failure

Principle 06: Separation of concerns in management

Alignment: DRAFT ETSI GS ZSM 002 V0.3.0 (2018-06)


ZSM Requirements based on documented scenarios

PoC Scenario and Use-Cases cover 50% of requirements

Future iterations of PoC will cover additional Scenarios and Use-Cases to demonstrate broader coverage

Assumptions

Day 2 demo running multi-vendor, multi-domain Network Service

Day 0-1 onboarding & deployment out-of-scope of this iteration of PoC

Design Time

Compose End-to-End Network Service: NSD with a) Packages plus b) reference to an SLA, exposed by API to c) ZSM Framework-based Solution

a. VNF Packages: where Package is described as VNFD plus metric, plus relationships to VNFM/LCM, and standards-based interfaces exposed by an API

b. SLA: – model FCAPS events using metadata/metrics to configure policies, trigger actions

c. ZSM Framework-based Solution: implementation-independent, minimum viable XML data models of event, policies, actions

Run-Time

Demonstrate ZSM Framework-based Solution: As per PoC Use-Case / Story
