Abstract: The present invention provides a cloud service packet redirection method and system, and a cloud gateway, the method performed by the cloud gateway includes, if the cloud gateway determines that a DNS packet that is forwarded by a router in a redirection manner is a cloud service-related DNS packet, a record is maintained in a cloud IP table of the cloud gateway according to the DNS packet. Policy route configuration information is sent to the router according to the record maintained in the cloud IP table to instruct the router to maintain a policy route. The policy route instructs the router to redirect, to the cloud gateway, a cloud service packet that is indicated by the DNS packet.

Abstract: The present disclosure provides a virtual desktop infrastructure VDI file transfer method, which relates to the communications field and can improve compressibility in a VDI file transfer process. The method includes receiving VDI messages, where the VDI messages at least include a VDI file transfer message, separating the VDI file transfer message from the VDI messages, parsing the separated VDI file transfer message; obtaining a data portion of the VDI file transfer message, compressing the data portion, and sending a VDI file transfer message that includes compressed data. The present disclosure further provides a corresponding apparatus.

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.
