TeraFlow: next step in telecom operators’ quest for open, virtual, and automated networks

Legacy routers have been traditionally built with both data plane and control plane hosted in the same device, with data plane running in specialized ASICs hardware, and control plane running in an x86 architecture. This approach has historically enabled network operators to meet the capacity and feature requirements of their networks, but at a significant

Toward True Self Driving Networks

5G networks require a significant increase in the number of cell sites as compared to their predecessors to support an enormous increase in the number of connected devices, from mobile phones to multitudes of IoT sensors. In addition, routing services are required in those locations to support the heterogeneous requirements in latency and bandwidth for

Hard vs. Soft Network Slicing: What’s the Difference (Part 3)

In the previous two posts of these series, we first introduced network slicing in the context of 5G cellular networks, as a way to fulfill the heterogeneous requirements of diverse types of applications by determining how network resources are assigned to different types of application traffic. We then saw there are two mechanisms in 5G

Hard vs. Soft Network Slicing: What’s the Difference (Part 2)

In the previous blog post, we introduced network slicing in the context of 5G cellular networks as a way to fulfill the heterogeneous requirements of diverse types of applications by determining how network resources are assigned to application traffic. We saw that network slicing needs to be available across all components of the 5G cellular

Hard vs. Soft Network Slicing: What’s the Difference (Part 1)

In our recent webinar with Jennifer Clark of Heavy Reading, Leveraging the Cloud in the New 5G Edge, we discussed the importance of network slicing in 5G. And, we went into detail about the difference between hard and soft network slicing. The webinar is available on demand here. 5G supports a new generation of applications

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

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
