Implement community entry management utilizing Cisco Trustsec and IEEE 802.1x. Acquire visibility of substation belongings, their communication actions and your safety posture with Cisco Cyber Imaginative and prescient. Management distant entry into belongings with Cisco Safe Tools Entry. All constructed into Cisco networking tools which have safe boot, signed firmware, and SUDI.
- Flexibility: Extremely modular platforms to assist switching, routing, synchronization, and edge compute wants
- Availability: Help for IEC62439-3 lossless community topologies and protocols (reminiscent of Excessive-Availability Seamless Redundancy [HSR] and Parallel Redundancy Protocol [PRP])
- Precision: Help for substation-wide time synchronization (for instance, the 2017 IEEE Precision Time Protocol – Energy Profile or IEC61850-9-3 PUP)
- Crucial features: Help for substation communications reminiscent of IEC 61850, Modbus, IEC 60870-5-104 (IEC 104) and Distributed Community Protocol 3 (DNP3)
- Simplicity: Vary of administration choices, together with Cisco Catalyst Heart for substation switching and Cisco SD-WAN Supervisor for SD-WAN routing capabilities
Evolution to phase routing and Ethernet VPN (EVPN) for substation WAN connectivity
Previous to phase routing, multi-protocol label switching (MPLS) packets had been forwarded utilizing label switching as an alternative of IP-based routing, which implies the routers forwarded site visitors primarily based on the label and never the vacation spot deal with. This required solely the “edge” routers to carry out an IP lookup, whereas intermediate “core” routers carried out solely a label lookup.
Sadly, MPLS didn’t take away complexity from an present community. The truth is, it added extra complexity by extra protocols and every MPLS node requiring the state to be synchronized throughout the complete community. As the dimensions of networks grew, so did the state and complexity, making it tougher to function and handle.
Section routing depends on a small variety of extensions to Cisco Intermediate System-to-Intermediate System (IS-IS) and Open Shortest Path First (OSPF) protocols. It may well function with an MPLS or an IPv6 information aircraft, and it integrates with the wealthy multi service capabilities of MPLS, together with Layer 3 VPN (L3VPN), Digital Non-public Wire Service (VPWS), Digital Non-public LAN Service (VPLS), and EVPN.
Section routing might be immediately utilized to the MPLS architectures with no change within the forwarding aircraft. Section routing makes use of the community bandwidth extra successfully than conventional MPLS networks and affords decrease latency.
EVPN
EVPN is the subsequent era L2VPN expertise, it supplies layer-2 in addition to layer-3 VPN providers in a scalable and simplified method. The evolution of EVPN began because of the want of a scalable answer to bridge numerous layer-2 domains and overcome the restrictions confronted by VPLS reminiscent of scalability, multi-homing, and per-flow load balancing.
Use instances thought-about within the new Cisco Validated Designs
Now we have 3 classes of providers to think about for the transport community:
- Layer 3 IP primarily based Substation to Datacenter: IP primarily based Scada information, IP primarily based CCTV, enterprise information and IP telephony.
- Layer 2 Non routable Substation to Substation: Layer 2 ethernet primarily based multicast protocols (reminiscent of IEC61850 GOOSE & SV), Digital machine migrations (for virtualised functions) and third occasion Scada site visitors.
- Layer 2 Substation to Substation for Conventional Teleprotection: Energy Safety providers, that are low latency level to level utilizing particular utility protocols and strict engineered paths throughout the community.
SEL Partnership
Cisco companions with Schweitzer Engineering Laboratories to offer the Teleprotection providers and interfaces inside the substation, that are through the SEL ICON platform. This platform supplies the interfaces required for substation safety gadgets whereas offering an Ethernet primarily based uplink to the Cisco Converged Transport community (NCS). SEL experience in grid automation is coupled with Cisco’s Industrial substation and converged transport community merchandise supplies a better of breed finish to finish answer.
