Embodiment 1

[0153] Example 1: Combining image 3 and Figure 4 The schematic diagram of the network framework is given. N virtual machines and virtual gateways corresponding to the N virtual machines are deployed in the first subnet, M gateways are deployed in the second subnet, and the switch implements DVR through logical entities. The function is implemented based on flow entries. Assume that there is a virtual machine VM1 deployed on the physical host 2 in the first subnet for the first time to initiate a business communication request to access Baidu on the external network. The IP address of Baidu is Remote. For details, see Figure 7 The flow chart of the communication is given as shown.

[0154] S200, the same as the traditional method, VM1 does not perceive the change of the external gateway and first sends an ARP request, and the normally sent ARP request will be sent to the virtual switch vSwitch1 where VM1 is located, and the ARP request is used to obtain the first subnet wh...

Embodiment 2

[0187] Embodiment two: see image 3 and Figure 4 The schematic diagram of the network framework is given. N virtual machines and virtual gateways corresponding to the N virtual machines are deployed in the first subnet, M gateways are deployed in the second subnet, and the switch implements the DVR through the container entity. The function is implemented based on routing table entries. Assume that a virtual machine VM1 deployed in the physical host 2 in the first subnet first initiates a business communication request to access Baidu on the external network, and Baidu's IP address is Remote. In the actual communication process, the SDN controller can generate a corresponding routing table according to the network topology information and routing policy of the network framework, and send / add the routing table to the relevant physical entities in the data forwarding system in advance (such as namespace , docker and other containers).

[0188] Exemplarily, it is assumed that...

Abstract

The embodiment of the invention discloses a data forwarding method and system, and a switch. The method is applied to the data forwarding system, the system comprises a first subnet and a second subnet, the first subnet comprises a virtual machine and is configured with a virtual gateway, the second subnet comprises a plurality of gateway entities, the method comprises the following steps: receiving a first data message carrying an IP address to a to-be-accessed target and an Mac address of the virtual gateway of the first subnet sent by the virtual machine by the switch; determining a target gateway entity matched with the first data message in the second subnet according to indication information of the first subnet and the first data message; and performing package according to the first data message, the Mac address of the target gateway entity and a network identifier of the second subnet to obtain a second data message, and forwarding the second data message to the target gateway entity. By adoption of the data forwarding method and system disclosed by the invention, the gateway performance and bottleneck congestion problems of North-South communication can be solved, and the waste of IP address of the service subnet in the prior art can also be avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a data forwarding method, related equipment and a system. Background technique [0002] As virtualization and cloud computing technologies become more and more mature, a large number of Internet applications begin to be cloudified. A lot of business logic is directly completed in the cloud, resulting in a sharp increase in east-west traffic in the data center. While increasing the communication load of the gateway, it also seizes the bandwidth of north-south traffic, especially when there is a lot of business traffic, it will affect the gateway. performance and reliability, and also reduces business communication efficiency. [0003] see figure 1 It is a schematic diagram of the application scenario of virtual machine (Virtual Machine, VM) communication between different subnets in the same routing domain or virtual private cloud (Virtual Private Cloud, VPC), ...
