Competition,New technologies

“Right sizing”“Right sizing”

• Workforce cuts in the late 80s and 90s

• Results:– skilled and experienced workers no longer available

• Level of automation is still low

• Service providers unable to fulfill demand for new services– High cost in time and staff– Quality loss during service activation

CPC TransactionsCPC Transactions

• Service Requests are encapsulated into transactions

• Transactions are network wide

• Transactions are atomic– Success: changes are committed in database– Failure: changes are rolled back

ThreadingThreading

• Threaders are supplied with resource models

• Generic threading algorithms– least cost, least number of hops– load leveling of NNIs

• Specify threading policies

ThreadingThreading

• Steps:

• NNI discovery

• Enumeration of candidate paths

• Selection of acceptable paths

• Path costing

• Path prioritization

ThreadingThreading

• Inter-network connections are discovered– Both logical ports must be unlocked– Both logical ports must support the same

protocol

• Candidate paths– loopbacks are rejected

ThreadingThreading

• Select acceptable paths– ports that sufficient bandwidth, available

connections– ports must be in the same VPN

• Bandwidth calculation– based on QoS attributes– separate calculations for Frame Relay and ATM

ScalabilityScalability

• Per CPC limits: 1M objects

• Increases can be supported via distributed architecture, nested CPCs– 1M subscriber aggregation points– 1M DSL provider ports per region

• Managed nodes: 20,000

• Concurrent sessions: 5

• VPN tags or Managed Domain tags can be added to CPC objects in the database (ie: nodes, cards, ports)

• Access privileges can be assigned per operator: administrator, operator, observer

• Each operator can be assigned to a managed domain or to a VPN that consists of specific objects
