VECTOR TECHNOLOGIES has been playing an active role in the Remote-PHY technology development from the very beginning of the standardization work. To get the most from the laboratory environment, VECTOR TECHNOLOGIES developed the CCAP Core Simulator (CCS), which has been demonstrated at the US and Europe-based interops and the Remote PHY interoperability events in Europe. The CCS allows Multiple System Operators (MSOs) for testing Remote-PHY Device (RPD) from different vendors to achieve full interoperability in compliance with the MHAv2 set of the specification. Thanks to the CCAP Core Simulator, MSOs can successfully secure Remote PHY deployment in their network. What’s more, the CCS will in the future enable fast adaptation to the Full Duplex DOCSIS 3.1® technology and any changes implemented in the MHAv2 set of specifications.
The CCAP Core Simulator (CCS) is a pure software validation platform that emulates the CCAP core with all logical layers/functions that are required for RPD proper operation – GCP, DEPI, UEPI, L2TPv.3 network services. Based on the custom build Linux operating system with various services and daemons to emulate CCAP Core in the Remote PHY architecture.
It is certain that the deployment of Remote PHY will change the way traditional HFC networks are installed, tested and serviced, especially as far as an optical layer is concerned. Remote PHY technology provides several major benefits to the HFC networks that bring cable TV and broadband internet services to subscribers and enterprises. Not surprisingly, MSOs are turning their attention towards Fiber Deep and Distributed Access Architecture (DAA) for their infrastructure.
The CCAP Core Simulator (CCS) is a network platform for validation, debugging, and prototyping for Remote PHY platforms. The solution is a pure software validation platform with various services and daemons to emulate CCAP Core in Remote PHY architecture. The CCS is a complete platform that allows MSOs for testing RPD from multi-vendors to achieve full interoperability in compliance with the MHAv2 set of the specification.
The CCS has been developed on the basis of COTS hardware and C++/Python languages which results in the easiness of the further development in accordance with the R-PHY specification, in the area of services and network functions. Any new features, adjustments, or necessary extensions may be efficiently and promptly introduced at the further stage of the product life.
The role of the CCAP Core Simulator in the market is essential. The purpose of our solution is simple: help the cable MSOs to achieve an interoperable and reliable solution as quickly as possible. Thanks to the CCAP Core Simulator, MSO can successfully secure DAA deployments in its HFC plant and reduce the operational cost. All the network bottlenecks caused by moving into Distributed Access Architecture can be easily identified before they will limit deployments.
Principal CORE – that controls all configuration and management of RPD
DOCSIS CORE – that corresponds to the DOCSIS function and cable modem communication
VIDEO CORE – that corresponds to the VIDEO function, like VIDEO encapsulation (static video stream)
OOB Core – that corresponds to the control RPD in signal processing, that is used in the HFC network like a sweep, HMS, FM (no data processing, only control function)
