This module explores the technology stack t hat underpins a modern software-defined media facility. Rather than focusi ng on dedicated broadcast appliances\, participants will gain an understan ding of the IT infrastructure that enables scalable\, high-performance med ia processing. The session covers the networking technologies\, including Ethernet\, RDMA\, RoCEv2\, and emerging developments such as Ultra Etherne t. It also introduces key server architecture concepts\, including NUMA to pology\, CPU affinity (core pinning)\, and GPU pass-through\, and explains why they matter for predictable application performance.
\n\nBuildi ng on this foundation\, the module examines virtualisation\, including hyp ervisors\, as well as Linux and lightweight Kubernetes platforms such as k 3s.
\n\nA key focus is the Media eXchange Layer (MXL)\, which abstra cts media handling away from underlying transport and compute. MXL enables media flows to be exchanged between applications in a consistent\, softwa re-defined manner\, regardless of physical location. It operates in two co mplementary modes: intra-node\, where media is exchanged efficiently withi n a single server across processes\, GPUs\, or containers\; and inter-node \, where media is transported across the network between distributed nodes using high-performance transport mechanisms such as RDMA or RoCEv2. This abstraction decouples applications from the complexity of the underlying i nfrastructure while maintaining real-time performance.
\n\nFinally\, the module highlights the architectural shift towards fully asynchronous systems. The emphasis moves from transport efficiency alone to overall com pute efficiency\, enabling scalable and flexible media facility design.

Rather than focusing on dedicated broa dcast appliances\, participants will gain an understanding of the IT infra structure that enables scalable\, high-performance media processing. The s ession covers the networking technologies\, including Ethernet\, RDMA\, Ro CEv2\, and emerging developments such as Ultra Ethernet. It also introduce s key server architecture concepts\, including NUMA topology\, CPU affinit y (core pinning)\, and GPU pass-through\, and explains why they matter for predictable application performance.\n\nBuilding on this foundation\, the module examines virtualisation\, including hypervisors\, as well as Linux and lightweight Kubernetes platforms such as k3s.\n\nA key focus is the M edia eXchange Layer (MXL)\, which abstracts media handling away from under lying transport and compute. MXL enables media flows to be exchanged betwe en applications in a consistent\, software-defined manner\, regardless of physical location. It operates in two complementary modes: intra-node\, wh ere media is exchanged efficiently within a single server across processes \, GPUs\, or containers\; and inter-node\, where media is transported acro ss the network between distributed nodes using high-performance transport mechanisms such as RDMA or RoCEv2. This abstraction decouples applications from the complexity of the underlying infrastructure while maintaining re al-time performance.\n\nFinally\, the module highlights the architectural shift towards fully asynchronous systems. The emphasis moves from transpor t efficiency alone to overall compute efficiency\, enabling scalable and f lexible media facility design. TRIGGER:-PT15M END:VALARM END:VEVENT END:VCALENDAR
