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.
