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 Cloud Connect Network 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, support for general lines, low latency, and low-cost smart path scheduling;

  • Based on QoS services, different qualities of line products are implemented.

Technical Implementation

  • Cloud Network Fusion

Each regional network element is made up of a business gateway (VPC gateway, POPGW, hosted gateway, dedicated line gateway) and cross-domain gateway (RPG) to form an integrated network element structure, implementing flexible networking for users’ public cloud, and SD-WAN networks.

  • Traffic Engineering

The underlying network of the Cloud Connect Network uses Segment Routing (abbreviated as SR) technology to simplify the complexity of the backbone network and realize traffic engineering, supporting multiple path scheduling capabilities.

  • Rigid / Elastic Bandwidth

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

  • Improved Forwarding Efficiency

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