Embodiment
[0039] In the gateway cluster-based robust forwarding method for cloud computing network traffic in this embodiment, the environment is a cloud computing platform; the cloud computing platform is composed of multiple computing nodes and gateway nodes. The flow of this embodiment is as follows figure 1 As shown, the method includes the following steps:
[0040] (1) Gateway cluster initialization. First, the central controller divides the gateways into several clusters and assigns several IP addresses to each gateway; then, the central controller assigns The VPC allocates a gateway cluster; finally, the central controller installs a default routing entry pointing to the gateway cluster for each computing node where the VPC is located according to the "VPC-gateway cluster" mapping scheme;
[0041] (2) Traffic forwarding and entry distribution. When two VMs deployed on different computing nodes communicate for the first time, the computing node of the source VM will send the in...
