Net Insight creates world first 100GbE IP Media Trust Boundary for Red Bee

Working with Red Bee Media, Net Insight has created the world’s first 100GbE IP Media Trust Boundary, supporting both ST-2022 and ST-2110 workflows. The deployment is used in Red Bee’s new IP-based, software-only managed playout service.

“Our existing technology was based around SDI which was increasingly limiting our ability to service customers with the flexibility and cost effectiveness they were going to need going forward,” explained Robert Luggar, head of playout engineering & platform at Red Bee. “Our challenge was to refresh the technology while keeping costs down. The time was right to rethink the whole topology.”

Red Bee began to flesh out a design that would be modular, multi-tenanted, uncompressed and cost effective. Disaster recovery was a key requirement, meaning each of the company’s UK playout sites would have to operate independently of the other.

Luggar explains the core principles they embodied in the design of the managed playout platform. “One was to be software-based. We wanted to run all application functionality as software components on generic platforms for network, store and compute.

“Another core tenet was to move to IP video transport rather than SDI. Related, was the need to build future-proofed networks on open-standards-based technology. Combine those macro pieces in the right way and you have a bedrock infrastructure that would enable us as service provider and our broadcaster partners to be sure of true flexibility and access to ongoing innovation.”

“Working through interoperability issues especially around IP video was a major hurdle,” said Luggar.

Red Bee intended to adopt the NMOS standard but hit a hurdle.

“As is the case with new standards there are differences in interpretation and implementation. We were trying to connect four different networks to each site with different address spaces which we needed to integrate into the NMOS routing control at each end. But none of that functionality existed to the degree we needed at any supplier.”

Although not optimised for NMOS in the way Red Bee required it to be, the company concluded that no other vendor had a better solution and engaged Net Insight as its preferred technology partner.

“We embarked on a journey to add the functionality we required to Nimbra specifically around support for NMOS routing and address translation,” Luggar added. “This would enable us to translate multicast streams between the networks. The source stream would be translated onto the right target network. Those were the two pieces of functionality we worked with Net Insight to build and deliver.”

Development took place over six months to January 2021. Net Insight and Red Bee teams worked with AMWA testing tools to guide the NMOS integration and issues around interoperability with other suppliers’ systems in Red Bee’s network.

It included the first deployment of Net Insight’s Media Pro Application, a fully programmable, adaptable and scalable foundation for handling high data volumes of ST-2022 and ST-2110 IP video, audio and data for demanding live events and production workflows.

“It was an excellent collaboration that worked really well from day one,” Luggar said. “We had very good access to their R&D team and we were able to help them by providing real world examples of workflow and systems in our video networks for them to build and develop against.”

Nimbra’s NMOS integration was tailored to work with Grass Valley Orbit as the Dynamic System Orchestrator for Red Bee’s networks. Since the Red Bee site has to be independently resilient, there are instances of Orbit at each location.

“Orbit bridges the worlds of broadcast and IP by allowing native broadcast applications to control IP routing fabrics,” explained Luggar. “It also acts as our NMOS registry for all our devices including Nimbra. Nimbra advertise its resources to and accepts routing commands from Orbit. It’s an integral component of the workflow that has worked extremely well.”

Security is a vital component for a reliable SDI-to-IP transition. In  principal, Red Bee could have connected its networks together over fibre with switches at either end but there would be no management of the connectivity, no ability to prioritise traffic across the circuits and no ability to control network routing.

“We are custodians for our customer’s media and services so security is vital in every respect,” Luggar stressed. “Since the connectivity that sits between our sites is point to point and dedicated to us then from an interception perspective the opportunities for nefarious parties to invade are quite limited.

“In terms of QoS, however, the integrity of the media and robustness of the connection is equally as important. The reason we buy solutions like Nimbra is because Net Insight has the track record and heritage of managing circuits like this.”

The Nimbra Media Pro app ensures media service delivery points within the network remain tamper-proof. To secure restricted delivery of approved IP media between operation centres on the 100GE WAN, the application leverages the IP Media Trust Boundary feature which strictly controls which IP media traffic is allowed to pass.

By being first to launch and with several months of managing uncompressed playout live end to end for one high-profile UK customer, Red Bee’s provisioning over 100GbE IP has attained an industry leading level of maturity.

NMOS-based orchestration creates the common language among multiple best-of-breed vendors enabling Red Bee to deliver stream control and management between sites and leverage a broad range of existing and future technologies from different partners.

“We have come from a world where we built bespoke installations for every single customer to a world where equipment is much more commoditised enabling us to provision things much more quickly, easily and cheaply,” Luggar said. “Because everything is based on commodity compute, network and store we can provision and scale easily and much faster than before. A lot of work we’ve done with Net Insight was on the tooling to achieve that.

“We’ve also developed configuration models which means we are able to remove a lot of the variability we had between customer solutions and systems. We don’t have to spend months developing a bespoke configuration to meet every nuance of a customer’s service. We now have a robust configuration model that we’re able to deploy for every customer and every circumstance quickly and easily.”

Luggar concluded: “Our customers expect us to be able to provision a service quickly and cheaply and in some cases for short periods, for instance for a major sporting event. These event-based services need to be set up quickly and as smoothly as any permanent channel, and customers expect us to be able to do that.

“From my perspective it has been a great example of collaborative working with a supplier to mutual benefit. Net Insight enhanced the capability of Nimbra and we got the functionality we needed ahead of anybody else.”
