Going Fiber Deep: Don’t Ignore Your Metro Core

Hybrid Fiber Coax, known as “HFC”, is the well-established cable access network architecture.  As the name suggests, HFC consists of two separate media connecting a cable head-end to the subscriber.  While the coax portion that connects to the subscriber gets most of the attention, the ‘heavy lifting’ is actually done by the fiber portion of the network. It’s here where we get the huge capacity necessary to deliver the content from and between cable head-ends, data centers, Internet PoPs and video server farms.

Why go ‘fiber deep’? 

Today, cable MSOs are migrating to a “fiber deep” approach that pushes fiber all the way to the local access node. This approach aims to support the next-generation distributed access architecture (DAA) in which the PHY function is distributed from its traditional location in the head-end, out to the local access point: a process known as Remote PHY, or RPHY.

With RPHY comes the ability to increase the capacity in the access network and, since 2016, MSOs both large and small have been doing this using new technologies such as DOCSIS 3.1 and full duplex DOCSIS (FDX). These technologies enable higher data rates and, in the case of FDX, symmetric downstream and upstream connectivity speeds up to 10Gbps.

With these technologies, MSOs can continue to leverage the installed coax network making it more economical to compete with the high-speed services offered by fiber-based providers.  However, these kinds of connections in the access (i.e., coax) network put enormous pressure on the metro core. Operating at these higher capacities, each subscriber is capable of consuming an entire wavelength, a situation that quickly exhausts capacity…

EKINOPS helps to bring optical transport a step closer to SDN

tunel-2055970_1920

Guillaume Crenn, EKINOPS Product line & Marketing Director, recounts a recent technical breakthrough enabling legacy optical equipment to function in tomorrow’s virtualized networks.

Interoperability remains one of the biggest challenges facing operators seeking to software define their networks. Powerful new frameworks, like OpenDaylight (ODL), are needed to disaggregate and rearchitect the network and enable the level of automation and programmability that will, eventually, deliver virtualization’s ‘new age’ of flexibility.

Designed by the Open Daylight Project - a global, collaborative community of vendor and user organizations, of which EKINOPS is a part - ODL is a modular, open framework designed to enable commercial solutions to address a variety of virtualized network use cases, such as automated service delivery, Cloud and NFV, resource optimization and network visibility and control.

A critical hurdle to overcome on the road to enabling such uses cases is how to establish the level of interoperability between the network’s newly separated components and functions in such a way that they can be managed and orchestrated. This is a complex task that requires utilizing controllers for both northbound and southbound communication throughout the virtualized network.

In the world of optical transport, enabling this controller-based communication in ODL is the job of OpenDaylight TransportPCE, a collaborative project led by Orange, EKINOPS and Orange Labs whose work describes an open-source application running on top of the OpenDaylight controller. Its primary function is to control an optical transport infrastructure using a non-proprietary South Bound Interface (SBI).
