Hello, everyone!
This post will share with you FusionCloud network architecture.
Network Architecture
The network architecture of FusionCloud adopts a flattened and two-level hierarchical design, which is divided into the aggregation layer and access layer.
Two typical deployment schemes (Region Type I and Region Type II) are recommended for the FusionCloud solution. Table1 lists the differences between Region Type I and Region Type II. Figure1 and Figure2 show more details.
Table1 Network architecture differences between the Region Type I and Region Type II scenarios | ||
Scenario | Aggregation layer | Access layer |
Region Type I | Perimeter Virtual Fire Wall (VFW). | Network nodes (provides ELB function) and VPN FW (provides VPN function for tenants) and cloud service nodes. |
Region Type II | Elastic Load Balance (ELB) and VFW. | Agile Controller. |

The two-level network deployment architecture has the following features:
Multiple DCs are connected to each other through the Internet, metropolitan area network (MAN), or multi-protocol label switching (MPLS) network.
At the aggregation layer, subrack switches (aggregation switch CE128 is recommended) are used to form a cluster, and multiple switches are logically virtualized into a switch to offer device redundancy. Only one management IP address is required to manage the devices.
At the aggregation layer, the virtual routing and forwarding (VRF) technology is used to perform Layer 3 isolation. At the access layer, the VLAN or VXLAN technology is used to perform Layer 2 isolation.
The network virtualization function can provide virtual firewalls (vFWs), virtual load balancers (vLBs), and virtual switches (vSwitches) to meet network requirements of different users.
That's all, thanks!
