About the Blog

Welcome to the official blog of RAD, a global telecom access solutions and products vendor. We’ll be blogging on a wide range of hot topics affecting service providers and critical infrastructure network operators. Our resident experts will be discussing vCPE, Cyber Security, 5G, Industrial IoT and much, much more.

We’re happy you’re here and we thank you for reading!

    Service Assured vCPE

    It is widely known that vCPE has the potential to deliver the NFV benefits that service providers desperately need. This however, comes with its challenges as we’ve already discussed in our analyst corner.

    Timing for 5G

    In this part, we would like to focus on the means to achieve the required timing accuracy goals. In particular, we would like to discuss the distributed PTP Grandmaster (GM) concept that is usually also associated with PTP-GM miniaturization.

    Timing for 5G

    Delivering sub-microsecond time accuracy to cellular base stations was one of the major challenges that cellular providers faced as they started to deploy their new LTE networks. This was further exacerbated by LTE-A’s stringent synchronization requirements and, now when 5G is at our doorstep, time accuracy requirements are being “stretched” again, challenging the boundaries of what physics can deliver.

    vCPE is More Challenging than It Seems – Here’s How Vendors Can Add Value

    A lot of telcos expected to achieve “open networking nirvana” with vCPE, by stitching their solutions from software elements that run on off-the-shelf white boxes. But practicalities of deploying in live networks favor a more sophisticated approach, and vendors should combine strengths of open networking with telco-grade capabilities.

    How to Tackle Industrial IoT’s Top 3 Challenges

    The industrial internet of things (IIoT) revolution goes hand-in-hand with digital transformation and we’re about to see their impact everywhere, most importantly in the industrial and critical infrastructure sectors.

    In the previous installment we discussed how SDN replaced distributed routing by centralized path computation. But SDN introduced an additional novel abstraction – the whitebox switch.

  • Aug 27, 2018

    As mentioned last time, SDN theorists declare that SDN is the networking technology that separates the forwarding plane from the control plane. Of course the logical separation of networking into planes has been conventional for three decades, and time-honored tradition distinguishes three planes – those of forwarding, control, and management.

    The concept of logical separation of a network’s operation into planes first surfaced during discussions in the ITU on ISDN in the 1980s. After initial proposals favored two planes, it was concluded that three planes were necessary, namely the forwarding plane, the control plane, and the management plane.

    In the last year or so, SD-WAN has caught the attention of service providers, with some of them going as far as investing in related startups. At the same time, service providers began to realize that while the technology provides easy-to-deploy solutions that include VNFs, white boxes and a management suite, these solutions are in effect walled gardens.

    The Truth about 5G

    5G is coming fast, promising to change – yet again – the way we connect to the world and consume data. It will enable ubiquitous wireless broadband, also known as enhanced mobile broadband (eMBB), (e.g., wireless-to-the-premises and broadband on high-speed trains, at events and in crowds) and other, entirely new market segments.
