New networking technology has always alluded to the positive outcomes it will bring to the table, a route to increase the good things with the network, where it goes even faster, bigger and more software- programmable. While there is a hidden balance at play here for the network operator, were they have to ensure that bad things don’t happen,
There are many challenges to achieve next generation networks. Many of the “marketed” benefits of 5G cannot be achieved unless the network allows new approaches to Security, End to End (E2E) Service Layers that are independent of lower layer resource allocation and guarantee Quality of Service (QoS). In fact ARCFIRE advisory board member Sue Rudd has gone one
What should be the main goal of any 5G architecture considering the network, service, and business, as well as operation, control and management. Is it to realise a largely self-governed network that adjusts its behaviour according to service requirements, business requirements, and instantaneous demand? I think those goals provide the frame for how the network
Up until now the common wisdom has been to support mobility by using tunnelling protocols to create bearer flows, but with the drive towards network virtualisation this same common wisdom will lead to tunnels, within tunnels, within tunnels. Seems madly inefficient and likely not to work. However, what if mobility is looked at as nothing more than
In a recent discussions with our ARCFIRE EAB member Sue Rudd, the topic of complexity in 5G comes up time and again, and it’s becoming a common theme in the chatter about 5G. As Sue points out, “Many Mobile Network Operators (MNOs) and their vendors view 5G as becoming increasingly complex since 5G focuses both on a
View on 5G Architecture and RINA, a US perspective
In a previous post, we discussed a view on 5G Architecture from the European 5G PPP Architecture Working Group, and now its worth considering recommendations for End-to-end 5G systems from the US perspective. The 5G Americas (formerly known as 4G Americas) whitepaper “5G Technology Evolution Recommendations” discusses a selected set of scenarios and technologies for 5G.
