Technical Field

The invention relates to a device and a method for dispatching traffic among working groups based on MAC partition VLAN, belonging to the technical field of computer networks.

Background

The great advantage of dividing VLANs based on MAC addresses is that VLANs do not need to be reconfigured when the physical location of a user moves, i.e. from one switch to another. Vxlan (virtual Extensible lan) is a network virtualization technology, which is based on IP network and adopts a two-layer VPN technology in the form of "MAC in UDP" encapsulation. The VXLAN technology creates a large number of virtual extensible local area networks on the existing Network architecture by establishing VXLAN tunnels, and different virtual extensible local area networks are identified by using VNI (virtual extensible local area Network Identifier). VXLAN provides the same layer 2 network services as VLAN, but with greater scalability and flexibility than VLAN. SDN (Software defined network) is an implementation manner of network virtualization, and a control plane and a data plane of a network device are separated, so that flexible scheduling of data traffic is realized, and a network becomes more intelligent as a transmission pipeline.

The invention mainly solves the problem that the flow scheduling can not be carried out after the PC connected with a HUB moves the position. The specific application examples are: the user of one internet cafe can call the resources of other internet cafes to surf the internet and play games. Based on the condition that the user calls resources in the internet bar, the internet flow accesses the internet from the called nodes of the resources of the internet bar, and if the PC of the internet bar moves, other internet bar flows can still be appointed to be called as long as the MAC address of the PC is unchanged.

The method comprises the steps of firstly discovering a full network topology by utilizing an SDN controller, and then configuring VLAN division based on MAC according to needs. The PC of an internet cafe is connected to the Leaf switch via the HUB. As shown in fig. 3.

Some internet cafes have more people and less people, the flow may need to be borrowed among the internet cafes, and the internet cafes with more people schedule the flow resources of the internet cafes with less people.

1. If the A internet bar needs to schedule the resources of the B internet bar, and the A and B internet bars are under the same Leaf node, that is, in the same operator node machine room as shown in FIG. 1. The configuration process is as follows (illustrated by the switch shown in fig. 4):

1.1 Leaf node switch ports 0-1 and 0-25 with IP 172.20.234.103 each add VLAN 100.

1.2, configuring VLAN 100 at port 0-1 of the switch with IP 172.20.234.102(SW-A), configuring VLAN based on MAC at port 0-5, wherein the MAC address is the MAC address of the PC to be dispatched, and the VLAN is consistent with the VLAN at the uplink port.

1.3, the switch configuration with 172.20.234.104(SW-B) IP is similar to 172.20.234.102, VLAN 100 is configured on ports 0-28, VLAN based on MAC is configured on ports 0-11, the MAC address is the MAC address of the scheduled PC, and the VLAN is consistent with the VLAN on the uplink port.

2. if the A internet bar needs to schedule the resources of the B internet bar, and the A and B internet bars are under different Leaf nodes, the configuration is as follows

2.1, SW-A and SW-B and Leaf are the same basic configuration as above.

And 2.2, deploying VXLAN on the Leaf node, and configuring and completing the mapping of the VLAN ID to the VXLAN.

And 2.3, accessing the same subnet across Leaf, taking the Leaf node as a VTEP of the VXLAN network, and building a VXLAN tunnel between the two leaves, so that the mutual communication between the PCs in the same network segment can be realized. As shown in fig. 5.
