Abstract

The invention relates to the technical field of computers, in particular to a virtualized network networking system and a data packet sending method. The virtualized network networking system at leastcomprises a central switch of a spine layer, a client VXLAN switch and a gateway VXLAN switch of a leaf layer, a client connected to the client VXLAN switch and a gateway cluster connected to the gateway VXLAN switch, wherein the gateway cluster at least comprises two gateway devices, the gateway VXLAN switch receives a packaging bag corresponding to the data packet, carries out de-encapsulation,determines a target gateway device from the gateway cluster, and sends the data packet to the target gateway device, so that the target gateway device carries out network address translation, and thus the data packet after network address translation is sent to a target server, the load balancing is realized through the gateway cluster, the data packet encapsulation and the forwarding logic are separated, and the gateway device implementation performance and data packet forwarding efficiency are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a virtualized network networking system and a data packet sending method. Background technique [0002] At present, in the scalable virtual local area network (Virtual Extensible Local Area Network, VXLAN) of cloud computing, different tenants have customized virtual networks, usually a virtual private cloud (Virtual Private Cloud, VPC), when accessing the transmission control protocol in the physical network (Transmission Control Protocol, TCP) or User Datagram Protocol (User Datagram Protocol, UDP) services, the data packets of the virtual network and the data packets of the physical network need to be exchanged through the VXLAN gateway, so that different tenants can use the virtual network. Internet Protocol (IP) address to access services under the physical network. [0003] In the prior art, see figure 1 As shown, it is a prior art VXLAN virtualized network networking s...
