Maintain the principle of uniformity in the scheduling strategy of the whole network, and use templated deployment as much as possible to facilitate network management

LPQ/WFQ scheduling strategies can be used to avoid low-priority services not being able to obtain bandwidth resources

The current QoS policy needs to take into account the subsequent expansion of the network

Core services and video-voice services should ensure the absolute priority of forwarding and use PQ scheduling

Unless the business has special requirements, some parameters of the scheduling policy should be defaulted as much as possible

For TCP-based services, the queue must be configured with WRED dropping to avoid TCP global synchronization

Deploy a VRF instance for each slice

Each VRF instance is configured with a routing policy to color a specific color

After the SRv6Policy tunnel in the slice matches the color, the VRF instance is iterated to the SRv6Policy tunnel in the corresponding slice after the head node matches the color.

FLEX-E technology is recommended for interfaces below 50GE and channelized interface technology for interfaces of 50GE and above.

Synchronize information between dual-gateway devices through the interlink control sub-interface, such as the synchronization and backup of application recognition results, overlay connection information, and connection quality information. Interlink serves as a dual-gateway device interconnection interface that forwards inter-device (VPN) traffic through sub-interfaces.

Interlink serves as a dual-gateway device interconnection interface, providing forwarding of inter-device service (VPN) traffic through sub-interfaces.

Interlink can be interconnected with a direct link, and when the site service traffic is large and the CPE port resources are sufficient, it is recommended that Interlink use an Eth-trunk link. Interlink cannot borrow Layer 2 service interfaces on the CPELAN side.

Interlink cannot borrow the Layer 2 service interface on the CPE LAN side
