This specification provides a method and an apparatus for controlling a flow entry. The method includes: receiving a data message sent by a user, and determining a target flow entry matched with the data message, where the target flow entry is one of at least one flow entry corresponding to a target virtual machine in a local position; in a case that a first version number of the target virtual machine included in the target flow entry is inconsistent with a second version number of the target virtual machine recorded in the local position, deleting a flow entry including the first version number in the local position; and sending the data message to a centrex, so that the centrex forwards the data message to a target host machine, where the second version number is generated in a case that the target virtual machine is migrated to the target host machine.

Method and apparatus for controlling flow entry

A message forwarding method and apparatus based on Remote Direct Memory Access, and a network card and a device. The method includes: acquiring payload data corresponding to an RDMA message to be forwarded; encapsulating a message header of the payload data by using a hardware module in a network card node to obtain a processed message; and forwarding the processed message by using the hardware module or a software module in the network card node.

Message forwarding method and apparatus based on remote direct data storage, and network card and device

A system including a transmission terminal, used for transmitting a target data packet obtained by encrypting and encapsulating a data flow; a network controller, deployed in a first Internet network and storing routing information from the transmission terminal to a receiving terminal; and a backbone transmission network device, deployed in a backbone transmission network and used for obtaining the routing information and the target data packet forwarded by the first Internet network and forwarding the target data packet to the receiving terminal based on the routing information. The present disclosure solves the technical problem of low efficiency and high cost of data transmission in the conventional techniques.

Data transmission method and system

A networking method including receiving, at an edge router of a cloud data center, a virtual private cloud ('VPC') network communication from a private network via a dedicated physical connection line to the edge router. The VPC network communication is forwarded to a gateway hardware group via a first connection using Virtual Extensible Local Area Network ('VXLAN') technology. The VPC network communication is then forwarded from the gateway hardware group to VPC of a user of the private network via a second connection using VXLAN technology to access a virtual machine ('VM').

Network system and method for connecting a private network with a virtual private network

Embodiments of the present invention provide a method for changing configurations at a client device is presented. The configuration changing method comprises: a) sending a heartbeat request message to a network device over a network, wherein the heartbeat request message carries a current first configuration change code of a client device; b) receiving from the network device a heartbeat response message in accordance with the first configuration change code, wherein the heartbeat response message carries a current second configuration change code of the network device; c) sending, in accordance with the first configuration change code and the second configuration change code, a request message to the network device for synchronizing configurations; d) obtaining configuration synchronization information sent from the network, synchronizing configurations of associated services according to the configuration synchronization information, and updating the first configuration change code in accordance with the results of the configuration synchronization.
