It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The method for accessing the public network by the subnet provided by the embodiment of the application can be applied to an application environment shown in figure 1. The cloud computing management platform 11 is used for acquiring subnet route information and flow data transmitted by a Virtual machine, the Virtual machine is used for managing and scheduling Virtual machine instances, distributing subnets (such as internet protocol version 6 and IPv 6) to the Virtual machine, realizing internal network communication, creating and managing a Virtual network, a Virtual Router (Virtual Router) is responsible for flow forwarding between the Virtual machine and an external network, the first routing node is used for establishing boundary gateway protocol (Border Gateway Protocol, BGP) connection with a Virtual Router in the cloud computing management platform and receiving the subnet route information from the cloud computing management platform, and the second routing node is used for establishing Open Shortest path first protocol (Open Shortest path first PATH FIRST, OSPF) connection with a physical switch and announcing IPv6 subnet route information to the physical switch. The first routing node 101 acquires the subnet route information sent by the cloud computing management platform 11, reissues the subnet route information to the second routing node based on the border gateway protocol, so that the second routing node 102 forwards the subnet route information to the physical switch 12 based on the open shortest path first protocol, and adds the subnet route information to the switch route table via the physical switch 103.
In an exemplary embodiment, as shown in fig. 2, a subnet access public network method is provided, and the method is applied to the first routing node 101 in fig. 1 for illustration, and includes the following steps 201 to 202. Wherein:
step 201, acquiring subnet route information sent by a cloud computing management platform.
The cloud computing management platform creates a subnet, distributes the subnet to virtual machine instances, ensures that each virtual machine has a unique subnet address, establishes connection with a first routing node in the intermediate forwarding platform based on a border gateway protocol, sends subnet route information to the first routing node, and obtains the subnet route information sent by the cloud computing management platform.
It should be noted that, the cloud computing management platform may introduce a dynamic routing (Neutron Dynamic Routing) component, and establish a connection with a first routing node in the intermediate forwarding platform through the border gateway protocol.
Step 202, reissuing the subnet route information to the second routing node based on the border gateway protocol, such that the second routing node forwards the subnet route information to the physical switch based on the open shortest path first protocol, and adds the subnet route information to the switch routing table via the physical switch.
The second routing node and the first routing node are deployed in the same intermediate forwarding platform. The intermediate forwarding platform reduces occupation of a neighbor table of the switch by centrally managing conversion between a border gateway protocol and an open shortest path priority protocol, and prevents network performance bottlenecks and faults caused by overlarge capacity of the neighbor table.
In one embodiment, an open shortest path first protocol is configured on a second routing node, an OSPF connection is established between the port on the second routing node and a physical switch, and the first routing node reissues sub-network routing information received by a border gateway protocol to the second routing node to realize conversion of the routing protocol, and then forwards the sub-network routing information to a public network through the physical switch to realize direct access of passive address conversion (SNAT).
