Questions from the Webinar: Leveraging the Cloud in the New 5G Edge

Is it possible that one Radio Unit (RU) is shared by multiple operators and then their respective traffic goes to their respective DUs, CUs, and MC? RAN sharing allows operators to reduce their capital expenses by providing a way for operators to share the same base stations instead of building them out separately.  It is

The Forecast is for Increasing Clouds

The cloud is getting its due in recent 5G news.  In our most recent post, we talked about the announcements of partnerships between the Big 3 in cloud and their spate of partnerships with mobile network operators (MNOs).  This brings the cloud platforms right into the mix for edge computing which is a major enabler

The Evolution to Virtual Routing – Part 1

There is tremendous interest in network virtualization and the benefits it can bring to service provider network deployments, especially for 5G. However, terms like legacy router, virtualized router, disaggregated router, virtual router, and network slicing may mean different things for different people. That sometimes gets in the way understanding the benefits of virtualization. The goal

The Impact of 5G on Peering

A great deal of attention is being paid to 5G RAN and transport. This makes sense because the greenfield buildout of small cell sites is will be significant.  The shorter range of 5G will drive the “densification” of small cell sites.  The Small Cell Forum estimates that the number of cell sites will grow from

Virtual Routing and 5G Transport: Your Questions from the Webinar

On December 10, Volta and Fujitsu co-sponsored a webinar hosted by IHS Markit featuring Heidi Adams, Executive Director, Network Infrastructure Research.  Our topic was Virtual Routing in 5G Transport.  Attendees received a special report authored by Heidi. If you missed it, you watch it on-demand here and download the report, the slides and several other

Virtual Routing at the TIP Summit

Volta is gearing up for the TIP Summit next week in Amsterdam on November 13 and 14.  This will a great opportunity to engage with members of a thriving collaborative community. The Telecom Infra Project (TIP) has over “500 Member organizations, including operators, technology providers, developers, integrators, startups, and a range of other entities inside

Lesson 5: Cost, Agility and Velocity

Server virtualization gained interest as a way to optimize costs. The processing capacity of servers had grown to a point where it was common to see very low utilization levels. Thus, there was enough processing available to add a hypervisor and run multiple workloads on a single server. IT departments could point to better server

Lesson 4: Multiple Workloads

In server virtualization, the key is thinking of an application as a workload.  A server with a hypervisor can run multiple, independent workloads.  This allows for better utilization of the server and much greater flexibility, agility, and responsiveness in managing workloads. In routing, we have seen many attempts to run multiple control plane workloads trying

Lesson 3: Compartmentalize change

The hypervisor was a technology that could be added to the existing mix that made everything work better.  The applications, the OS and hardware were all the same after the hypervisor was introduced into the mix. As a result, the focus could be on prioritizing what workloads to virtualize enabling a gradual introduction of the

Lesson 2 of 5: Embrace commodity hardware

x86 processors from Intel and AMD were used by a range of server ODMs. Moore’s Law held and these chips grew in raw processing power. It meant that the need for custom silicon greatly diminished. Custom silicon was common – think of Sun servers running Sun’s own SPARC processors. Commodity should not be viewed as
