Mobile backhaul and aggregation


5G architectures are set to dramatically expand both the number of sites and the volume of IP traffic that needs to be carried across mobile networks. These new network architectures need a new approach to IP routing.

RtBrick's carrier routing software is a highly scalable and economical way of deploying and operating IP networks to provide backhaul connectivity and aggregation in 4G and 5G mobile networks. It can be deployed on general purpose x86-based hardware at small sites or on bare-metal switches deeper into the network to provide highly scalable IP aggregation at a fraction of the cost of conventional router networks.

Mobile and multi-service edge

RtBrick’s software provides separation of the Control and User Planes, with the control layer distributed across the physical bare-metal switches for higher performance and resilience. Network segmentation can be implemented using MPLS, L2 or L3 VPN technologies.

The same platform can also supply full BNG (Border Network Gateway) functionality, so you can also use it to terminate residential subscribers on a converged multiservice edge.

Operating a disaggregated mobile network

You can manage your whole network from a single browser window, using the RtBrick Management Suite. And you get automation straight out-of-the-box. Simply power-on your bare metal switches and they will self-register, download the correct software image, discover their topology and all microservices self-start. Automated software version management reduces risk of human error, and new microservices can be updated and tested independently of other operating software. The system also includes tools to simplify repair, such as ‘clone a switch’ for zero-touch replacement of broken hardware. And there’s in-depth alarm and status management, with thresholds and abnormalities automatically flagged: from data rates to fan speeds. You can glue this into your existing OSS using REST and RPC APIs, such as gNMI (Google Network Management Interface). The cost will be significantly lower than traditional systems.
