- Vodafone, Benu Networks, Casa Systems, Cisco and Nokia test paves the way for faster open broadband networks.
- Test validates Broadband Forum global standard for interoperability between different vendors
Vodafone, together with Benu Networks, Casa Systems, Cisco and Nokia, have successfully tested a system that will make it quicker and easier to deliver faster fixed broadband services to new and existing customers across Europe.
In a world first, the companies applied a new open architecture to the Broadband Network Gateway (BNG) – a critical component for connecting multiple users to the Internet – to enable it to work using separate software and hardware from multiple vendors. This is an important step in opening up the current single-supplier, monolithic broadband gateways to greater technological innovation from a more diverse supply chain.
Called Disaggregated BNG, the technology will change the way broadband networks are built. Using the global TR-459 standard devised by the Broadband Forum, the test allowed the core control functions of the gateway, such as authenticating a user and increasing bandwidth to support streaming services, to be separated and managed efficiently in the cloud whilst ensuring multi-vendor interoperability. Vodafone can then separately upgrade, scale and deploy new features and add more capacity, enabling greater agility and faster time to market when making enhancements across its pan-European broadband network.
Johan Wibergh, Chief Technology Officer for Vodafone, said: “We are already driving a more diverse and open mobile ecosystem with Open RAN, and now we are targeting fixed broadband. As an industry, and with government support, we owe it to people with no or slow internet access to quicken the rollout of new capabilities on fast, fixed broadband.”
Disaggregated BNG will also lower development costs for existing and new ecosystem partners and allow deeper integration with 5G.
