Product Overview

Cisco Prime

™

Network Registrar DHCP for Connected Grid offers scalable, high-performance, and fault tolerant

Dynamic Host Configuration Protocol (DHCP) services. Based on industry standards, the solution provides the IP

address assignment and management required for IP network access for millions of connected grid endpoints. This

helps support the Cisco

Connected Grid vision to transform energy production, distribution, and consumption

using an end-to-

end IP platform to sustainably meet the world’s future energy needs.

Utilities are investing to add digital intelligence to their transmission and distribution networks, and digital

intelligence requires connectivity. One of the main challenges with connecting large numbers of devices is

providing a unique identifier, or address, for each device. DHCP provides the IP connectivity needed to manage

and implement distributed networks, a virtually impossible task to undertake manually.

Given the increasing number of connected homes, businesses, and connected devices (as well as the need to

support both IPv4 and IPv6 for smart meters and grid router devices), a high-capacity dual-stack DHCP server is
an imperative for today’s utility.

Migration to IPv6

The introduction of IPv6 into network environments presents significant challenges and added complexity. The

Internet Assigned Numbers Authority (IANA) address pool was exhausted on February 3, 2011, and the Regional

Internet Registry (RIR) address pools have already begun to run out of allocatable IPv4 addresses. And IPv6 offers

straightforward addressing and routing for a huge network such as the connected grid. Hence, most utilities are

focusing on IPv6 as a component of their implementation. Network operators implementing connected grid

solutions require DHCP systems that support IPv4 and IPv6.

Cisco Prime Network Registrar DHCP for Connected Grid supports the IPv4 to IPv6 transition and allows dual-

stack deployments on a single server. The solution helps utilities to develop a multiservice network v6 and

provides:

●

Support for grid security - for example, digital certificates using authentication, authorization, and accounting

(AAA)

●

New opportunities to run multiple applications over multiple physical topologies. Examples of those

applications include:

◦

Integration with and monitoring of renewable energy sources

◦

Better ability to monitor grid performance with the goal of reducing volt/VAR (voltage levels and reactive

power) optimization losses

◦

Smart metering

●

Ability to implement network quality of service (QoS)

●

Scale to millions of endpoints
