How is the bandwidth calculated in the AF and EF queues on a tunnel interface

9

The tunnel interface is a virtual interface that cannot sense the bandwidth on the physical interface. Therefore, the following requirements are specified:
-If the qos gts command is not executed on the tunnel interface, the available bandwidth is 1 Gbit/s.
-If the qos gts command has been executed on the interface, the available bandwidth is the value of cir.

In which situation do EF queues preempt the idle bandwidth
When traffic is not congested on a device interface and AF or BE queues have idle bandwidth, EF queues can preempt the idle bandwidth. When the SRU80, SRU200, SRUX5, or SRU400 is used, Ethernet interfaces and POS interfaces do not support idle bandwidth preempted by EF queues.

When a conference is initiated on the MCU, how do I calculate the network bandwidth occupied by the MCU?
When a conference is initiated on the MCU, the network bandwidth occupied by the MCU is the sum of network bandwidth occupied by all participants. For example, if 10 participants join a 2 Mbit/s conference, the network bandwidth occupied by the MCU is 20 Mbit/s (2 x 10).

Paths for downloading the bandwidth calculation document
You can obtain the bandwidth calculation document in the following ways: 1. Contact the project coordinator via WeChat, email, or phone. 2. Post your request on Huawei's cloud computing forum (http://support.huawei.com/huaweiconnect/enterprise/forum-775.html). 3. Contact Huawei technical support by dialing the 400 hotline.

How are interface priorities calculated
The priority of the VGMP group is lowered by 2 only when: -A physical interface in the VGMP group fails. -An Eth-Trunk interface in the VGMP group fails. The failure of a member interface of the Eth-Trunk does not affect the priority of the VGMP group. -A member interface of the VGMP group in a VLAN fails. -A member interface of an IP-Link fails.

How to configure Assured Forwarding (AF) for packets of a certain type on an AR
On AR routers, you can run the queue af command to configure Assured Forwarding (AF) for packets of a certain type and set the minimum bandwidth. AF ensures a low drop probability of packets when the rate of outgoing service traffic does not exceed the minimum bandwidth. It is applied to services of heavy traffic whose bandwidth need to be ensured. Configuration example: Set the minimum bandwidth for the traffic of network segment 192.168.100.0 to 3000 kbit/s. [Huawei] acl 3022 //Configure an ACL to match traffic for which traffic is to be assured. [Huawei-acl-adv-3022] rule permit ip source 192.168.100.0 0.0.0.255 [Huawei-acl-adv-3022] quit [Huawei] traffic classifier c [Huawei-classifier-c] if-match acl 3022 //Create a traffic classifier to protect the traffic matching the ACL rule. [Huawei-classifier-c] quit [Huawei] traffic behavior b [Huawei-behavior-b] queue af bandwidth 3000 //Create a traffic behavior and set the minimum bandwidth to 3000 kbit/s. [Huawei-behavior-b] quit [Huawei] traffic policy p [Huawei-trafficpolicy-p] classifier c behavior b //Create a traffic policy and bind the traffic classifier and traffic behavior to the traffic policy. [Huawei-trafficpolicy-p] quit [Huawei] interface Ethernet 0/0/0 [Huawei-Ethernet0/0/0] traffic-policy p outbound //Apply the traffic policy on the interface.
