摘要： The present invention provides a data forwarding method, device, and system in software-defined networking. An SDN control device delivers a proactive flow entry according to network topology information, where the proactive flow entry is unrelated to a service, but only related to the network topology information. After being delivered, the proactive flow entry may be reused during data forwarding. After data is received, the SDN control device delivers reactive flow entries to some switching devices, where the reactive flow entries are related to the service, but are delivered only to some switching devices. This reduces flow entries delivered by the SDN control device to some switching devices, so that occupation of resources of the SDN control device and a switching device by flow entries is reduced.

摘要： Embodiments of the present invention disclose a software-defined data center, and a deployment method for a service cluster therein. An SDN controller manages a cluster by using a shared IP address. The SDN controller obtains an online virtual machine event that is sent by an edge switch accessed by a new online virtual machine; obtains a MAC address of the new online virtual machine, and identifies the new online virtual machine; after identifying the new online virtual machine, identifies whether an IP address of the new online virtual machine is a shared IP address; and if the IP address of the new online virtual machine is the shared IP address, deploys the new online virtual machine to a service cluster corresponding to the shared IP address. The SDN controller automatically completes creation, capacity expansion, capacity reduction, and deletion of the service cluster by using the method in the present invention, so that no manual intervention from a tenant is required, and tenant experience is good.

摘要： Embodiments of the present invention disclose a software-defined data center and a service cluster scheduling and traffic monitoring method therefor. The SDN controller implements a scheduling and decision function of load balancing. As a load balancer, the SDN controller follows a serving node load balancing principle, and customizes a packet forwarding flow table to instruct an edge switch to direct user traffic to a specified serving node. The SDN controller may monitor load of a serving node in a service cluster, execute a load balancing function of the load balancer according to a load monitoring result, and select a target virtual machine. By using the SDN controller as a load balancer, a dynamic expansion capability of the SDN may be multiplexed at a control layer, and a network resource of the SDN network may be multiplexed at a network forwarding layer. Implementation complexity is low, and investment costs are low.

摘要： Embodiments of the present invention disclose a networking method for a data center network and a data center network, where the data center network includes multiple deployment units; each deployment unit includes at least two Spine switches and at least one Leaf Switch; each Leaf switch inside each deployment unit is connected to at least two Spine switches of all Spine switches inside the deployment unit; and between at least two deployment units, at least one Spine switch inside each deployment unit is connected to at least one Spine switch inside each of other deployment units. A connection relationship between Spine switches in deployment units is set up, so that in a condition of adding no network device, communication between different deployment units can be implemented, which decreases network complexity, and increases the network management and maintenance efficiency.
