Abstract: An address resolution method uniformly processing ARP broadcast packets by an address server to avoid broadcasting in the network, so that the occupied bandwidth is reduced. The method also includes storing by a network device and terminal address correspondence information of local and remote terminals in communication with one another, which reduces the size of the MAC table in the data center network, reduces the load of the network device, and improves the processing capabilities of the network device, so that it is possible to deploy a large layer-2 network to thereby solve real-time relocation problems of a virtual machine.

Abstract: A network management method. The method includes: obtaining a network type of a target network; obtaining a logical network model of the target network based on the network type and a logical network recommendation model; determining a physical network model of the target network based on the logical network model and a physical network recommendation model; and performing network configuration based on the physical network model of the target network. An advantage of the embodiments lies in that, when a user inputs the network type of the target network instead of a large quantity of detailed network configurations, a network management system can automatically establish the required target network for the user, thereby greatly improving efficiency of establishing the target network.

Abstract: The application discloses a method and a system for information synchronization between cloud storage gateways and a cloud storage gateway, to resolve a problem that an address obtained by a cloud storage gateway is usually a dynamic address or even a private address, and it is difficult to perform direct communication and impossible to perform directory synchronization. A cloud storage gateway obtains, from a cloud message queue of a cloud service provider, a directory distributed by another cloud storage gateway; and therefore, as long as the cloud storage gateway can communicate with the cloud service provider, directory synchronization can be implemented without a need of direct communication between the cloud storage gateways. Therefore, even through an address obtained by the cloud storage gateway is a dynamic address or a private address, directory synchronization is not affected.

Abstract: A traffic switching method, a device, and a system where, a software-defined networking (SDN) controller acquires a first state of a target gateway, where the target gateway belongs to an SDN gateway group, the SDN gateway group is used to forward traffic that is transmitted between a first network node and a second network node, and multiple forwarding paths on which multiple gateways in the SDN gateway group are located form multiple equal-cost paths between the first network node and the second network node. The SDN controller sends an Address Resolution Protocol (ARP) entry to the target gateway according to the first state, and changes, of the multiple equal-cost paths, a metric value of a forwarding path on which the target gateway is located from an original value to a first value, where the first value is greater than the original value.
