Embodiment 1

[0044] This embodiment provides an SDN cloud network implementation method based on an FPGA accelerator card, including steps:

[0045] S1, when the same access is the same as the cloud main machine of the same node server, the service network card uses SR-IO technology, virtually several virtual network cards, and binds the corresponding virtual network card to cloud main machine; network packet is bound to the cloud main machine The virtual network card is issued, after entering the service network card, forward the network packet to the first 10,000 megabyte port of the FPGA accelerator card through the fiber line.

[0046] S2, the network packet decryption function of the FPGA accelerator card parses the network packet, match the content of the network packet with the matching field of the OpenFlow flow table entries in the FPGA acceleration card.

[0047] S3, if the FPGA Acceleration Card performs the matching OpenFlow flow table rule action, return the network packet to the ...

Embodiment 2

[0054] This embodiment provides another method of implementing an SDN cloud network based on an FPGA accelerator card, which is:

[0055] Network packets enter the network device conditions, this implementation, when the cloud host accesses the external network external network, the network device is a business network card, the business network card virtual sever a virtual network card, and tied the corresponding virtual network card Set to the cloud main machine, the network packet is sent from the virtual network card bound by the cloud main machine. After entering the service network card, then forward the 10,000 megabyte port of the FPGA accelerator card.

[0056] In addition, after the FPGA accelerator card performs OpenFlow flow table rules, it is not true. In this embodiment, the FPGA Acceleration Card performs OpenFlow flow table rules, network packets are forwarded to The first 10,000 megabylet port of the FPGA accelerates the TOR switch connected to the node server.

Abstract

The invention discloses an SDN cloud network implementation method based on an FPGA accelerator card, a device thereof and equipment, the method comprises the following steps: when a network data packet enters network equipment, forwarding the network data packet to the FPGA accelerator card; after the FPGA acceleration card analyzes the network data packet, performing OpenFlow flow table rule matching on the network data packet; if yes, executing the matched OpenFlow flow table rule action by the FPGA accelerator card and forwarding the matched OpenFlow flow table rule action to the network equipment; if not, notifying the user mode from the kernel mode, and sending the data packet to the virtual machine control process; and when the control process inquires that the OpenFlow flow table rule in the user mode is matched, issuing the flow table to the FPGA accelerator card to execute the matched OpenFlow flow table rule action, and forwarding the matched OpenFlow flow table rule action to the network equipment. The FPGA acceleration card is added, the kernel data forwarding processing module of the virtual switch is unloaded to the FPGA acceleration card, Openflow rule flow table matching and data packet forwarding are achieved, and the problem that a large number of CPU and memory resources of a cloud node server are occupied by a traditional SDN cloud network method achieved through pure software is solved.

Description

Technical field [0001] The present invention belongs to the field of cloud network, and in particular, a method, apparatus and apparatus for implementing an SDN cloud network based on an FPGA accelerator card. Background technique [0002] In the prior art, the implementation of the cloud network generally adopts the SDN cloud network, and the virtual switch is controlled based on the OpenFlow control protocol, and the control and management of the cloud host network is implemented. Traditional SDN cloud network implementation figure 1 As shown, the data package enters the data forwarding process module of the virtual network of the physical network or cloud host into the kernel, which matches the OpenFlow flow table rule according to the data packet content. If the match is forwarded according to the rule action, if not Matching is notified from the kernel to the virtual switch control process through the NetLink mode. If the control process queries the user's OpenFlow flow tabl...
