IP Fabric for Media

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, is 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 has the capacity to carry multiple bidirectional traffic flows and can support different flow sizes without requiring changes to the physical infrastructure. The solution uses Cisco Nexus 9000 Series switches in conjunction with the Cisco non-blocking multicast (NBM) algorithm (an intelligent traffic management algorithm) and with or without the Cisco DCNM Media Controller to provide a highly reliable (zero drop multicast), highly visible, highly secure, and highly available network.

Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I7(1) supports three deployment methods:

·         A spine-leaf topology with the DCNM Media Controller—A flexible architecture for large-scale deployments typically seen in an IP studio

·         A single modular switch with the DCNM Media Controller—An architecture suitable for fixed deployments, with the controller providing features such as flow visibility, security, and monitoring

·         A single modular switch without the DCNM Media Controller—A simple deployment method for environments such as outside broadcasting (OB) vans

Supported Device Hardware

Table 2 lists the hardware that the Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I7(1) supports. For additional information about the supported hardware, see the Hardware Installation Guide for your Cisco Nexus 9000 Series device.

New Hardware Features

Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I7(1) does not include new hardware features.

New Software Features

This section lists the new software features in Cisco Nexus 9000 Series NX-OS IP Fabric for Media Release 7.0(3)I7(1).

■        Added the ability to connect devices in a redundant way to two leaf switches in an IP fabric for media network. This feature ensures traffic flows through the network if one device fails.

■        Added classification support for multicast and unicast traffic, where multicast traffic is assigned to a priority queue. This feature enables IP fabric for media to use unicast and multicast traffic.

■        Added support for Source-Specific Multicast (SSM) groups so two sources can transmit to the same multicast group.

■        Added XML support for the NBM show commands.

For more information on these features, see the Cisco Nexus 9000 Series IP Fabric for Media Solution Guide.

Upgrade and Downgrade Instructions

If you want to migrate from Cisco NX-OS Release 7.0(3)I4(2), you must upgrade your switches to Cisco NX-OS Release 7.0(3)I7(1) and completely change the configuration as the switches need to be reconfigured in NBM controller mode. You also need to modify the TCAM allocation. Because most deployments are built using redundant networks, with minimal or no disruption to production, each side of the fabric can be upgraded one after the other.

To perform a software upgrade or downgrade, follow the installation instructions in the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide and refer to the Cisco Nexus 9000 Series NX-OS Release Notes, Release 7.0(3)I7(1) for specific upgrade and downgrade information related to the release.
