Network Architecture

Utility Internet Technology (IT) and Operational Technology (OT) networks are often as important to utilities as the power systems. As utilities move from legacy circuit-switched OT formats to newer packet-switched formats over private and public fiber communications media, more care must be taken to ensure NERC CIP compliance and to meet internal cyber and physical security needs.

PSE can help navigate the multitude of network architecture options for legacy system upgrades and greenfield network deployments.

Our services include:

  • Strategic planning for replacing legacy serial and SONET-based OT networks and media to scalable modern optical transport networks (OTN)
  • Design of GigE, Carrier Ethernet or MPLS-IP networks using DWDM
  • Design of GPON and other consumer broadband networks
  • Leverage of DWDM for fiber strand management
  • Design of Field Area Networks for distribution automation and connecting remote devices

We help our clients to determine the best way to safely operate IT and OT data services on the same communications medium while maintaining network segregation. Our team will create a forward-thinking roadmap to manage the transition from legacy systems to new networks architectures.
