Discover a new era in network simulation and optimization

R-PHY System Scaling Tools accurately simulate control plane interactions between virtual R-PHY devices, cable modems, service cores, and critical network services. 

One solution. Multiple benefits.


Avoids physical device procurement, connectivity, provisioning lab space, network wiring & configuration, power, cooling and physical security.

Accurate control
plane emulation

Virtual RPDs support real-time communication with DOCSIS service cores and comply with CableLabs standards


Validated with CCAPs, vCMTS and RPDs from leading providers


Thousands of virtual R-PHY devices and cable models can be simulated simultaneously to provide control plane insights for entire service areas and regions


Virtual RPD Simulation

Enables fast and accurate large-scale RPD simulation

Virtual Cable Modem Simulation

Enables verification of network policies and DOCSIS service core operation

Virtual RPD

Virtual R-PHY devices support real-time,
bi-directional communication simultaneously
with multiple DOCSIS service cores over the GCP and L2TPv3 protocols. They seamlessly interact with critical network services such as NAD, DHCP, Time-of-Day and PTP servers.

They adhere to CableLabs, IEEE and IETF specifications, and have been validated with physical CCAP devices and vCMTS instances from leading vendors.

Unlock cost-effective and standards-compliant simulation at scale

Virtual RPD Simulation

  • Cost-efficient control plane simulation
    Reduces the need for configuring and maintaining physical RPDs
  • High-scale simulation
    Entire service areas/regions can be simulated at once to validate network architecture
  • Secure network access
    Supports 802.11x for authenticating network access
  • Real-time telemetry export
    Metrics from all RPDs under test can be recorded and visualized in detail

Virtual Cable Modem

Simulates the control plane interaction between thousands of DOCSIS 3.1 and 4.0 cable modems and DOCSIS service cores, and network services such as DHCP, ToD, TFTP, and SNMP servers. This enables rapid and cost-effective validation of DOCSIS service core compatibility, operation and performance, and network policies such as IP address and bandwidth allocation.

Simultaneously, the need to procure, connect, power, maintain, and secure hundreds or thousands of physical cable modems can be significantly reduced.

Improve capacity planning

Simulate difficult-to-replicate network events such as modem initialization storms following a network outage
