About the IP Fabric for Media Solution
Today, the broadcast industry uses a serial digital interface (SDI) router and SDI cables to transport video and audio traffic. The SDI cables can carry only a single unidirectional signal. As a result, many cables, frequently stretched over long distances, are required, making it difficult and time-consuming to expand or change an SDI-based infrastructure.
Cisco’s IP fabric for media solution helps transition from an SDI router to an IP-based infrastructure. In an IP-based infrastructure, a single cable can carry multiple bidirectional traffic flows and can support different flow sizes without requiring changes to the physical infrastructure.
The IP fabric for media solution consists of a flexible spine and leaf architecture or a single modular switch topology. The solution uses Cisco Nexus 9000 Series switches with the Cisco non-blocking multicast (NBM) algorithm (an intelligent traffic management algorithm) and with or without the Cisco Data Center Network Manager (DCNM) Media Controller. Using open APIs, the Cisco DCNM Media Controller can integrate with various broadcast controllers. The solution provides a highly reliable (zero drop multicast), highly visible, highly secure, and highly available network.
Cisco’s IP fabric for media solution supports the following types of deployments:
Spine-leaf topology—Flexible architecture for large-scale deployments that are typically seen in an IP studio.
Single modular switch—Architecture suitable for fixed deployments, with the controller providing features such as flow visibility, security, and monitoring.
Cisco's IP fabric for media solution supports a spine-leaf topology that consists of multiple spine and leaf switches. The topology supports any combination of leaf switches, including using just one type of leaf switch.
Media sources and receivers connect to the leaf switches, and receivers initiate IGMP join requests to the leaf switches in order to receive the media traffic.
Single Modular Switch Topology
Cisco's IP fabric for media solution supports a single modular switch topology that consists of one Cisco Nexus 9500 Series switch.
