Architectural Principles for IT Systems 12/03/2020 15:10 Layering Ops response Improvement Service Fulfilment Service view vs network view with relationships between service & network resources Provide an enriched and correlated alarm to operations and not bombard them with hundreds of isolated, unrelated events. Service fulfilment needs a real time, e2e path computation service. This path computation service needs to take BT and customer constraints into account Development Capability & Flexibility Architecture Complexity System Resilience & Availability Minimize System Integration costs 5 9’s availability Short lead time to support new services creation Top Functional Requirements Top Non-Functional Requirements These Functional Non functional requirements drove us towards using Neo4J Graph Database
- 8. The Requirement • Ingest a snapshot of the topology of the current network • Set up a path computation service to calculate a path from a source to multiple destinations considering the following constraints – • Node and Link Diversity - The primary and protected paths cannot use the same links and nodes • Cost of the Link – which is function of latency and bandwidth • Bandwidth Optimization - for a tree, we split as late as possible so as to optimize node and link bandwidth usage • MPLS constraint – we don’t loop back to a node we visited when calculating a path • The time between call and response needs to be in milliseconds 8 Security classification.

- 10. The Requirement • Create an SIA service on top of Neo4j • We call this API using the identifier of the node/link that failed • This internally queries the database and calculates 1. Services impacted 2. The type of impact – e.g. is this a loss of resilience/loss of service 3. Customers impacted • We can consolidate this information and instead of flooding ops with hundreds of alarms, only send enriched and correlated alarms • The time between call and response needs to be in milliseconds 10 Security classification.
