Abstract: This application provides a packet transmission method, an apparatus, and a system in an overlay network. Network address translation and reverse network address translation are implemented at a demarcation point: an IP tunnel end point, between the logical network and the physical network, an IP option is expanded to carry a source-end network element identifier and a destination-end network element identifier, and a virtual machine in an upper-layer logical network is interconnected with a peer-end virtual machine through a lower-layer physical network by using an IP tunnel.

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.

Abstract: A software-defined data center, and a deployment method for a service cluster are described 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: This application discloses a network, including a first switch, a second switch, and a controller. A management port of the first switch is connected to a first forwarding port of the first switch, and a third forwarding port of the first switch is connected to a fourth forwarding port of the second switch. In a boot phase of the network, the first switch communicates with a DHCP server by using a preset flow table, and obtains an IP address of the first switch. Then, the controller learns a connection relationship between forwarding ports of the first switch and the second switch by using a probe packet and a probe flow table, so as to control the first switch and the second switch.

Abstract: A software-defined data center (SDDC) and a service cluster scheduling and traffic monitoring method therefor. A software defined networking (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. 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.

Abstract: A network, including a first switch, a second switch, and a controller, where a management port of the first switch is coupled to a first forwarding port of the first switch, and a third forwarding port of the first switch is coupled to a fourth forwarding port of the second switch. In a boot phase of the network, the first switch communicates with a Dynamic Host Configuration Protocol (DHCP) server using a preset flow table, and obtains an Internet Protocol (IP) address of the first switch. The controller learns a connection relationship between forwarding ports of the first switch and the second switch using a probe packet and a probe flow table in order to control the first switch and the second switch.
