Example for Configuring Flow Recognition on a Media Network

This section provides an example for configuring flow recognition on a media network.

Networking Requirements

Figure 1 shows a typical media network. The functions of each node are described as follows:

Controller: delivers control instructions to the device to control, manage, and monitor the system.
Device: provides functions such as forwarding, replication, scheduling, clean switching, and flow recognition of media traffic.
Multimedia terminal A: functions as the transmit end of media signals and transmits traffic to the device.
Multimedia terminal B: functions as the receive end of media signals and receives traffic from the device.

On the network:

Multimedia terminal A transmits video and audio streams to the device.
The device collects the streams on the inbound interface, and reports each stream's septuple information (source and destination MAC addresses, source and destination IP addresses, source and destination port numbers, and protocol type) and other information (such as the numbers of packets and bytes) to the controller.
The controller calculates the stream rate based on the information to identify audio and video streams.

Figure 1 Typical media network

Interface 1 in this example represents GE 0/1/1.

Configuration Roadmap

The configuration roadmap is as follows:

Configure an IP address and a routing protocol for each interface so that all the nodes can communicate at the network layer.
Configure static telemetry subscription.
Configure flow recognition.

Data Preparation

To complete the configuration, you need the following data:

Interface 1's IP address: 10.1.1.1
Controller IP address: 10.1.1.2; port number: 10001
Telemetry sampling path: huawei-flow-recognition:flowrecognition/streaminfos/streaminfo
Proto file used for flow recognition: huawei-flow-recognition.proto

Procedure

Configure an IP address and a routing protocol for each interface so that all the nodes can communicate at the network layer. For configuration details about the device, see Configuration Files.
Configure static telemetry subscription. For configuration details, see Configuration Files.
