OptimizationSimplification

Each service has its own network

A mix of networking technologies

All services in one network

Business application use cases

• Make sure to have a good use case inventory• Interface types

• Protocols

• Data rates

• Latency/asymmetry

• Availability

• Owners/consumers

• QoS/CoS

SDG&E use cases

• Protective relaying

• Distribution and transmission SCADA

• Synchrophasors (PMU and PDC)

• Digital fault recorders

• Seismic sensors

• Security access control

• Security camera DVR

• Condition-based maintenance

• Wi-Fi

Guiding principles

• Improve service availability

• Implement component and system redundancy (MTTR)

• Achieve operational situational awareness (MTTR)

• Eliminate aging infrastructure (MTBF)

Design topics

• Network Integration

• MPLS services (VPLS, VPRN, PW)

• QoS

• Redundancy

• Encryption

• Timing redundancy for pseudowire services• Sync-E• PTP• Distributed GPS timing• High quality clocks for holdover

• Network Management Systems

Lessons learned

• Substation power system and environmental impacts

• End-to-end device communications design

• Define cutover processes early on

• Microwave/fiber construction/refresh

• Leased service evaluation

Lessons learned

• Define internal, partner and contractor roles clearly and up front

• Document stakeholder requirements and use cases as soon as possible

• Lab testing is crucial

• Don’t underestimate organizational change impact

• Everyone will tell you it can’t be done until it can
