Example: Configuring QoS for the branch and sub-branches in the financial industry

Applicable hardware and software versions

This configuration example is applicable to B75D071SP and B75 trunk of the H3C SR series high-end router.

Network configuration

As shown in Figure 1, the network of a bank branch typically includes two data center networks, one business network, one external network, one office network, one sub-branch access network. The edge devices of different networks are connected to the core switches of the branch center for interconnection. Access routers in the branch center (routers indicated by the blue box in the diagram), connect to sub-branches through leased network services provided by the operator. QoS policies are configured on interface XGE3/1/2 and XGE3/1/3 of this router to mark the local precedence of different business packets. This enables different business traffic heading towards sub-branches to enter separate queues for scheduling. Configure a QoS policy on interface XGE3/1/1 of the router to schedule traffic in different queues, ensuring preferential handling for critical business such as voice and video by using strict priority scheduling, reducing latency. Allocate reasonable scheduling weights using the WRR scheduling method for other business as needed.

‌

Table 1 The network service types and QoS requirements for the branch center

Service Type	Business description	Priority queue	Queue scheduling method
Key businesses (Key)	Host-to-host services and protocol packets require prioritized processing.	CS6	Use SP to ensure highest scheduling priority and appropriately rate limit the traffic based on the actual bandwidth.
Video and voice services (Voice_Video)	Video conferencing, voice, and other highly real-time services	EF	Use SP to ensure second-highest scheduling priority and appropriately rate limit the traffic based on the actual bandwidth.
Interactive services (Interactive)	Interactive operation services	AF3	Use the Weighted Round Robin (WRR) scheduling method, and assign higher scheduling weights.
Batch services (Batch)	Batch operations with a large amount of data	AF2	Use the Weighted Round Robin (WRR) scheduling method, and assign moderate scheduling weights.
Office (Office automation)	Office services and real-time monitoring of sub-branches	AF1	Use the Weighted Round Robin (WRR) schedule, and assign the lowest scheduling weight value.

Restrictions and guidelines

Due to the limited bandwidth of leased operator network lines, it is necessary to connect a router at the sub-branch to uniformly limit all traffic from the branch center to the sub-branch, in order to avoid congestion and packet loss.

Prerequisites

On the access router at the network node, it is necessary to preconfigure ACL rules based on different business traffic characteristics, such as traffic packet source and destination addresses, source and destination port numbers, protocol numbers, and other information, in order to differentiate different business traffic.

Example: Configuring QoS for an overseas bank branch to connect to the headquarters

Applicable hardware and software versions

This configuration example is applicable to B75D071SP and B75 trunk of the H3C SR series high-end router.

Network configuration

As shown in Figure 2, the two egress routers of a bank's overseas branch, AR 1 and AR 2, are connected to the aggregation routers AGG 1 and AGG 3 at the domestic headquarters through an international dedicated line and an Internet VPN dedicated line, respectively, enabling the overseas branch to access the data center at the domestic headquarters. The international dedicated line is the active link for forwarding traffic. When it fails, the traffic can fail over to the Internet VPN line. There are various types of businesses between overseas branches and the headquarters of the bank, such as mainframe business, voice business, video business, interactive business, batch business, office business. Bandwidth competition might occur between various businesses. In order to ensure priority service for critical businesses under any link conditions, a unified QoS queue scheduling mechanism is adopted across the entire network.

· For the downstream traffic from the headquarters to the overseas branch:

¡ On AGG 1 and AGG 3, QoS policies are deployed on interface XGE3/1/2 and XGE3/1/3, respectively, to identify the types of services, and map different types of services to different queues for scheduling.

¡ Deploy a user profile on interface XGE3/1/1 of AGG 1 and AGG 3 to connect with the overseas branch, uniformly rate limit all business traffic, and apply a queue scheduling profile to set scheduling mechanisms for different queues.

· For the upstream traffic from the overseas branch to the headquarters:

¡ Apply CBQ queue scheduling directly on interfaces XGE3/1/1 of AR 1 and AR 2, distinguish services of different applications, and configure different queue scheduling mechanisms for different service traffic.

Figure 2 Network topology for connecting the overseas branch to the headquarters

Table 2 Services and corresponding QoS requirements

Service Type	Business description	Priority queue	Queue scheduling method
Key businesses (Key)	Host-to-host services and protocol packets require prioritized processing.	CS6	Use SP to ensure highest scheduling priority and appropriately rate limit the traffic based on the actual bandwidth.
Voice services (Voice)	Video office	EF	Use SP to ensure highest scheduling priority and appropriately rate limit the traffic based on the actual bandwidth.
Video services (Video)	Voice communication	AF4	Use SP to ensure second-highest scheduling priority and appropriately rate limit the traffic based on the actual bandwidth.
Interactive services (Interactive)	Interactive operation services	AF3	Use the Weighted Round Robin (WRR) scheduling method, and assign higher scheduling weights.
Batch services (Batch)	Batch operations with a large amount of data	AF2	Use the Weighted Round Robin (WRR) scheduling method, and assign moderate scheduling weights.
Office (Office automation)	Office services and real-time monitoring of sub-branches	AF1	Use the Weighted Round Robin (WRR) schedule, and assign the lowest scheduling weight value.

Restrictions and guidelines

Due to limited dedicated line bandwidth, it is necessary to uniformly limit the traffic of all flows to avoid congestion and packet loss.

Prerequisites

On AGG 1, AGG 3, AR 1, and AR 2, ACL rules need to be preconfigured based on different traffic characteristics, such as source and destination addresses, source and destination port numbers, protocol numbers, to differentiate different types of traffic.
