Configuring UCC

About UCC

Unified Communication and Collaboration (UCC) can identify packets of specific protocols and increase the priority of the packets accordingly to accelerate packet forwarding and improve user experience.

Restrictions: Hardware compatibility with UCC

Support for this feature depends on the AC model and AP model.

The following compatibility matrixes show the support of ACs for UCC:

Configuring UCC AP and AP group white lists

About this task

Perform this task to allow only APs that belong to the UCC AP or AP group white list to collect and report UCC statistics to AC, reducing AC pressure from too many AP reports. In this way, pressure is also released for APs that do not belong to the UCC AP or AP group white list, because they no longer collect or report UCC statistics to AC.

Restrictions and guidelines

Only UCC APs for audio and video traffic are restricted by the white list.

Procedures (AP white list)

1.     Enter system view.

system-view

2.     Configure the UCC AP white list.

UCC configuration examples

Example: Configuring SIP-based UCC

Network configuration

As shown in Figure 1, the SIP server installed with third-party VoIP server software acts as both the SIP agent server and SIP registration server to manage SIP user registration and respond to user calls. Client 1 and Client 2 use the AC as their gateway, and they can call each other through the client software installed on them. Centralized forwarding is configured.

Configure UCC to optimize multimedia traffic between the clients.

Figure 1 Network diagram

 

Procedure

1.     Assign IP addresses to interfaces, as shown in Figure 1. (Details not shown.)

2.     Verify that the APs can associate with the AC and the clients can obtain an IP address.

3.     Configure the SIP server:

Install third-party VoIP server software, and configure a username (telephone number) and password for the clients.

4.     Configure Client 1 and Client 2:

Install third-party VoIP client software, specify the IP address of the SIP server, username (telephone number), password, and other parameters.

5.     Configure the AC:

Example: Configuring Skype4B-based UCC

Network configuration

As shown in Figure 2, all network users use Skype4B for communication.

The Skype4B server (including front-end and back-end) manage user registration and calls, and the Dialog Listener listens for Skype dialogs on the AC. The two servers are deployed on the same physical server.

The SDN Manager obtains dialog information from the Dialog Listener and establishes an HTTP or HTTPs connection with the AC to issue dialog information.

The AC is the client traffic forwarder, and the switch is the gateway for the clients. The clients use Skype4B client software to place calls to each other.

Configure Skype4B-based UCC on the AC to optimize Skype4B traffic between the clients to provide high-quality Skype4B services.

Figure 2 Network diagram

 

Prerequisites

Assign IP addresses to interfaces, and make sure the devices can reach each other.

Make sure the APs can associate with the AC and the clients can obtain an IP address.

Deploy the Skype4B server, Skype4B client, SDN Manager, and Dialog Listener.

Procedure

# Enable the device to communicate with the Skype4B server and specify the port number as 5000. Make sure this port number is the same as the port number configured on the SDN Manager.
