Shared bandwidth implementation method and device and cloud computing platform

The invention provides a shared bandwidth implementation method and device and a cloud computing platform, and relates to the technical field of computers, and the method comprises the steps: creating a first filter corresponding to each first target floating IP at a gateway port based on target shared bandwidth information and a first root queue configured at the gateway port of a target virtual router, creating a target virtual port in the namespace of the target virtual router; and based on the first root queue and each first filter, importing the inbound traffic received by each first target floating IP into the target virtual port, so that the target virtual port limits the sum of the inbound traffic received by each first target floating IP to be less than a first speed limit value. According to the method and the device for realizing the shared bandwidth and the cloud computing platform provided by the invention, the shared bandwidth of a plurality of floating IPs can be realized based on Linux TC and
