Part 3: The Evolution to Virtual Routing

In the previous two parts of this three-post series, we have provided a taxonomy for routers based on how their data plane and control plane components are implemented. We have put emphasis on disaggregated routers in the context of telecom operators, where the data plane is usually implemented in hardware, and the control plane implemented

Part 2: The Evolution to Virtual Routing

In the prior post on virtual routing, we introduced the concept of a disaggregated router. Disaggregated routers are routers where control plane and data plane are provided by different vendors. The control plane is usually implemented in software. The data plane could be implemented in either hardware or software. For example, the use of a

Questions from How to Futureproof your 5G Transport Network

This month, we are focused on virtual routing especially as it related to the new 5G service edge. We recently spoke on an Omdia webinar How to Futureproof your 5G Transport Network. We answered several questions that relate to virtual routing that we thought would be of broad interest. Question: Today, the 4G RUs and

Why Virtualization is Critical to 5G

5G opens up a new world to operators. According to the Ericsson Mobility Report, 5G subscriptions are forecast to reach 2.8 billion globally by the end of 2025  while GSMA Intelligence forecasts that total IoT connections will double between 2019 and 2025, reaching 24 billion. But what do MNOs need to get ready for the

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

Looking Back and Forward

As 2019 winds down, Volta has been asked several times about our thoughts on what was significant in 2019 and our predictions for 2020. In 2019, we saw the tipping point in service providers moving to open networking from legacy infrastructure. The key was the availability of carrier-grade switching ASICs from vendors like Broadcom. A
