Building A Media Fabric That’s Ready For The Future

Modern live events, from global broadcasts like the Olympic Games to massive concerts, present significant technological challenges. Audiences now expect flawless, high-fidelity, and immersive experiences. The underlying infrastructure must support massive, uncompressed video streams with ultra-low latency and exceptionally high reliability, as any downtime is unacceptable. Addressing these requirements necessitates a transition from conventional Serial Digital Interface (SDI) based networks to a purpose-built, intelligent IP based media fabric. These fabrics are engineered for the specific demands of live production, providing scalability for current 4K and the future 8K/16K video resolution and the agility to support future technological innovations such as AI.

What Really Matters When Building a Future-Ready Media Fabric?

Constructing an infrastructure to support current and future live events requires focusing on several core technical pillars. The media fabric is an intelligent, automated, and secure foundation engineered for real-time media and emerging computational workloads.

• Capacity Planning for Bandwidth Growth 
  The adoption of higher resolutions creates exponential growth in bandwidth requirements. A single uncompressed 8K video stream (ST 2110-20) consumes approximately 48 Gbps, while a future 16K stream will require nearly 100 Gbps. A future-ready fabric must therefore have a clear path to 400G and 800G Ethernet. Additionally, the hardware needs to be capable of supporting maximum 96Gbps bandwidth rate per flow. Architectures based on high-density platforms like the Cisco Nexus 9000 Series switches are capable of providing the non-blocking capacity for thousands of simultaneous uncompressed flows.
• The Requirement for a Lossless Network
  In professional broadcasting, a single dropped packet can result in visual or audible artifacts. Achieving a lossless network is therefore critical. Non-Blocking Multicast (NBM) is a key technology for this purpose. As a bandwidth-aware intelligence mechanism, NBM verifies that sufficient bandwidth is available along the entire network path before admitting a new multicast flow. This, combined with technologies like Precision Time Protocol (PTP) for synchronization, provides the deterministic, zero-packet-loss environment required for 8K, 16K, and beyond video transport.
• Security Through Granular Policy Enforcement
  In distributed production workflows, a zero-trust security model is necessary. Cisco’s IPFM architecture enables the implementation of granular host and flow policies to secure content. Host policies control which devices can send or receive specific media streams, acting as an admission control for sources and receivers. For instance, a camera can be restricted to send its stream only to a specific production switcher. These policies apply to individual media flows, ensuring that only authorized devices can subscribe to specific multicast groups and that all network elements operate with the principle of least privilege. Flow policies provision bandwidth and apply Quality of Service (QoS) markings for individual traffic flows, ensuring network performance and preventing endpoints from exceeding configured rates.
• Automation, Orchestration, and Telemetry
  The complexity of modern media workflows is impractical to manage manually. The Cisco Nexus Dashboard provides a centralized point of automation that abstracts the IP Network. Nexus Dashboard provides flexible APIs and leverages standard protocols like NMOS IS-04/IS-05 to integrate with the broadcast controllers.

  
  Beyond orchestration, the Cisco Nexus Dashboard offers deep, real-time telemetry for operational visibility using RTP flow monitoring. Cisco's Real-time Transport Protocol (RTP) flow monitoring provides significant benefits by offering granular visibility into the quality and performance of real-time applications like voice and video. By analyzing the health of RTP streams, network administrators can proactively identify and troubleshoot issues that would otherwise degrade the user experience and impact on-air performance. Additionally, Cisco Nexus Dashboard offers comprehensive PTP (Precision Time Protocol) flow monitoring capabilities as part of its flow telemetry and traffic analytics features such as topology view for Boundary Clock implementation and Mean Path Delay statistics.

Readiness for AI and Machine Learning Workloads

A key area of development in media is the integration of Artificial Intelligence and Machine Learning for tasks such as real-time analytics, automated captioning, real-time content analytics, AI-driven replay and automated graphics. The emerging Media Exchange Layer (MXL) addresses the need for high-performance data exchange between media applications and AI/ML processes. The Media eXchange Layer (MXL) is an open-source framework designed to standardize how media processing functions operating within virtualized and containerized environments can efficiently share and exchange data. A media fabric built on Cisco Nexus 9000 infrastructure can support this framework, allowing AI/ML workloads as well as containerized media to coexist with traditional NBM 2110 flows within the same fabric. We can achieve this by sending AI/ML workloads or containerized media workloads across applications directly over Remote Direct Memory Access (RDMA). This architecture reduces latency by enabling direct access to media streams for immediate inference, transforming the network from a transport layer into an active component of the content creation process.

Real-World Deployments: Future-Ready in Action

The practical benefits of an IP-based media fabric are demonstrated by its performance in demanding live production environments. This infrastructure is designed to manage significant scale, complexity, and stringent quality standards in settings ranging from sports arenas to global broadcast events. Two such recent examples are Monumental Sports & Entertainment and the 2024 Paris Olympic Games.

Monumental Sports: The Arena as a Media Hub

Monumental Sports & Entertainment (MSE) upgraded its Capital One Arena by utilizing a comprehensive Cisco infrastructure. The core of its in-venue media production is Cisco’s IP Fabric for Media (IPFM), a scalable network designed for the high-volume traffic of live sports and entertainment.

The architecture is based on Cisco Nexus 9000 Series switches in a spine-leaf topology, providing a non-blocking, high-bandwidth backplane for transporting thousands of simultaneous uncompressed media streams. The network is managed via the Cisco Nexus Dashboard, which offers a centralized interface for configuration, monitoring, and automation. This control is essential for managing the dynamic environment of live production, enabling engineers to provision and route flows efficiently.

Cisco’s IPFM infrastructure ensures secure, zero-loss delivery of 4K video content to all endpoints, including scoreboards, digital signage, and broadcast outputs. The fabric is a foundational layer in a converged network that also supports Wi-Fi 7 for fan connectivity and Cisco Spaces for venue analytics, with end-to-end visibility provided by Cisco Thousand Eyes. This integrated approach converts the arena into a dynamic, AI-ready media ecosystem orchestrated from a central Cisco Command Center.

The Paris Olympics: IP Production at Global Scale

For the 2024 Paris Olympic Games, broadcasters such as France Télévisions executed a large-scale media production based entirely on a standards-based IP infrastructure. This initiative required a media fabric to support a fully remote, studio and distributed workflow for Ultra High Definition (UHD) broadcasting.

The deployment utilized a dual-plane spine-and-leaf architecture compliant with the SMPTE ST 2110 standard. Two identical, physically separate fabrics (Red and Blue) were implemented to achieve hitless redundancy as specified by SMPTE ST 2022-7, ensuring uninterrupted media flows in the event of a failure.

To manage the bandwidth from thousands of uncompressed UHD signals, the network was built with high-density 400G connectivity. For the fabric’s spine, they used the modular Cisco Nexus 9808 chassis with Cisco Silicon One ASICs, providing the non-blocking throughput required to make any source available to any destination.

The intelligence of the fabric is managed by the Nexus Dashboard (ND), which abstracts network complexity and provides a programmable interface to broadcast controllers via open APIs. This allowed engineers to orchestrate media flows without requiring deep networking expertise, demonstrating the simplicity of IPFM for complex live events.

Conclusion

The migration from SDI to IP is not just a technological upgrade, its a strategic transformation that redefines how live content is created and delivered.  As demonstrated by major sporting and entertainment events, success now depends on an intelligent, lossless, and automated media fabric that can scale effortlessly to 400G and 800G.

With innovations such as Non-Blocking Multicast (NBM), PTP synchronization, and API driven orchestration via Nexus Dashboard, Cisco continues to set a benchmark for next-generation broadcast infrastructure. Additionally, through its Cisco Validated Designs (CVDs), broadcasters gain a comprehensive, tested blueprint which they can leverage to deploy, scale and secure these environments. These architectures are designed to reduce implementation risk and accelerate their journey towards AI-enabled networks for the future.
