Server bandwidth improving method suitable for cloud computing

The invention relates to the technical field of cloud computing, in particular to a server bandwidth improving method suitable for cloud computing. The server bandwidth improving method comprises the following steps: firstly creating a new virtual network interface in a physical server, configuring the virtual network interface to be a load balancing mode, distributing an only MAC address to the virtual network interface; then installing a plurality of network cards in the physical server, setting each of the network cards to be a slave unit, setting the virtual network interface to be a master unit; when an external user accesses the virtual machine, computing a result according to the user MAC address by the virtual network interface, returning the MAC address distributed to the physical network card to the external user, after the external user receives the response, recording the MAC address corresponding to the IP address in the virtual machine in a cache, and then using the physical network card corresponding to the MAC address when the external user accesses the virtual machine. The server bandwidth improving method disclosed by the invention can avoid the bandwidth bottleneck of the single physical network card, achieves the load balancing effect, and can be used for improving the bandwidth of the server.
