Technical Architecture

Product Model

• Integration of user private sites, hosted networks and VPC networks in the cloud, implementing a unified underlying networking and product.

• The UGN consists of network instances, routing tables, bandwidth packages, etc.

• Whole network interconnection, easy management, automatic learning and distribution of multi-node routing.

• Based on SR-TE technology, it supports intelligent path scheduling such as general lines, low latency, and low cost.

• Based on QoS services, it realizes line products of different qualities.

Technical Realization

• Cloud-Network Integration

Each regional network element is an integrated network element structure composed of service gateways (VPC gateway, UWAN gateway, hosted gateway, dedicated line gateway) and cross-region gateways, enabling flexible networking for users’ public clouds, SD-WAN networks, hosted services, and dedicated line services.

• Traffic Engineering

The underlying network of the cloud networking simplifies the complexity of the backbone network through Segment Routing (SR for short) technology to achieve traffic engineering and supports multiple path scheduling capabilities.

• Rigid/Elastic Bandwidth

By deploying QoS services at the exit of the backbone network, bandwidth guarantee and elastic bandwidth are realized.

• Improved Forwarding Efficiency

The forwarding plane adopts MPLS technology to replace VXLAN+NVGRE technology, realizing packet header compression and improving forwarding efficiency.
