BISDN joins TIP vBNG

Berlin, 28.01.2021

BISDN is contributing its longstanding expertise in disaggregating broadband network gateways (BNG) to the Telecom Infra Project’s (TIP) OpenBNG initiative. This initiative is run by TIP’s Disaggregated Open Routers (DOR) sub-group within the Open Optical and Packed Transport (OOPT) Project Group. The technical requirements recently published by the group are very much in line with BISDN’s technical approach.  

BISDN’s BNG uses an open source software stack that can be deployed in commercial-off-the-shelf equipment. Internally, BISDN’s BNG has its control plane decoupled from the data plane, allowing a flexible placement and offloading of its network functions. The data plane uses a Data Plane Development Kit (DPDK)-based solution that benefits from high-performance hardware-acceleration, which has previously shown to comfortably handle huge volumes of subscriber traffic while maintaining a low packet processing overhead. BISDN’s BNG can operate on any whitebox switching fabric that is able to fulfill the aggregated bandwidth requirements.

Within TIP, the Tier 1 carriers Telefónica, Deutsche Telekom, BT and Vodafone have joined forces to define their requirements for truly open and disaggregated BNG devices, that meet the needs of current and future networks. Their goal is to overcome some of the issues that operators face when providing fixed access to a diverse range of customers. Challenges such as continuous traffic growth affect both the required performance and the decision as to where to locate the BNG best (more centralized or more distributed). 

TIP operators will soon initiate a joint RFI for OpenBNG, which will be issued based on their collective requirements. Supplier products will then be tested and validated in labs and in the field during the upcoming months, and TIP Exchange badges awarded according to the results.

About BISDN: BISDN GmbH is a team of international network automation experts based in Berlin. The company has been self-funded and profitable since the year of its institution, 2012. With a track record in NFV-based telco applications, we are set to whitebox the entire network for the benefit of our customers and the industry.  

About the Telecom Infra Project: The Telecom Infra Project (TIP) is a global community of companies and organizations that are driving infrastructure solutions to advance global connectivity to transform global connectivity. Half of the world’s population is still not connected to the internet, and for those who are, connectivity is often insufficient. This limits access to the multitude of consumer and commercial benefits provided by the internet, thereby impacting GDP growth globally. However, a lack of flexibility in the current solutions – exacerbated by a limited choice in technology providers – makes it challenging for operators to efficiently build and upgrade networks. Founded in 2016, TIP is a community of diverse participants that includes hundreds of companies – from service providers and technology partners, to systems integrators and other connectivity stakeholders. We are working together to develop, test and deploy open, disaggregated, and standards-based solutions that deliver the high-quality connectivity that the world needs – now and in the decades to come.
