Abstract: The present disclosure discloses 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; then 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 of the service cluster, so that no manual intervention from a tenant is required, and tenant experience is good.

Abstract: Data forwarding method, device, and system are provided for 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, and instead related to the network topology information. 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 to a subset of 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.

Abstract: 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.
