Problems solved by technology

[0004] However, the traditional DHCP zero-configuration does not consider the situation of device loops, or requires complex protocols such as STP (Spanning Tree Protocol, Spanning Tree Protocol) to solve the loop problem
The SDN access device is only responsible for packet forwarding, without complex protocols such as STP, which leads to the problem of management channel looping in the SDN network under the loop access topology.

Embodiment 1

[0094] Embodiment 1. A configuration method applied to an SDN controller, such as figure 1 shown, including:

[0095] Step 101: The SDN controller receives the DHCP request message sent by the second SDN access device sent by the first SDN access device through the first Openflow protocol message;

[0096] Step 102: When the SDN controller confirms that the DHCP request of the second SDN access device has not been processed, control the establishment of a management channel between the first SDN access device and the second SDN access device.

[0097] Wherein, the SDN controller controls the establishment of the management channel between the first SDN access device and the second SDN access device in the following manner:

[0098] Sending first configuration information to the first SDN access device, where the first configuration information is used to instruct the first SDN access device to add the port receiving the DHCP request message from the second SDN access device t...

Embodiment 2

[0171] Embodiment 2. A configuration device, applied to an SDN controller, such as Figure 7 shown, including:

[0172] The first receiving module 701 is configured to receive the DHCP request message sent by the second SDN access device sent by the first SDN access device through the first Openflow protocol message;

[0173] The first processing module 702 is configured to, after the first receiving module 701 receives the DHCP request message encapsulated by the first Openflow protocol message, and when confirming that the DHCP request of the second SDN access device has not been processed, control the establishment of the first SDN connection management channel between the ingress device and the second SDN access device.

[0174] Wherein, the first processing module 702 is further configured to not process the DHCP request message of the second SDN access device when it is confirmed that the DHCP request message of the second SDN access device has been processed.

[0175]...

Embodiment 3

[0188] Embodiment 3, a configuration method, applied to the first SDN access device, such as Figure 8 shown, including:

[0189] Step 801: After receiving the DHCP request message sent by the second SDN access device, the first SDN access device transmits the DHCP request message of the second SDN access device to the SDN controller through the first Openflow protocol message;

[0190] Step 802: According to the first configuration information delivered by the SDN controller, add the port receiving the DHCP request message from the second SDN access device to the management VLAN.

[0191] Wherein, before step 801, an Openflow connection has been established between the first SDN access device and the SDN controller.

[0192] Wherein, the first Openflow protocol message may include a Packet in message. That is, after receiving the DHCP request message sent by the second SDN access device, the first SDN access device encapsulates the DHCP request message of the second SDN acc...

Abstract

This paper discloses a configuration method, device and system; a configuration method applied to an SDN controller, comprising: the SDN controller receives the second SDN access device sent by the first SDN access device through the first Openflow protocol message When confirming that the DHCP request of the second SDN access device has not been processed, control the establishment of a management channel between the first SDN access device and the second SDN access device. The above configuration method can prevent the management channel from forming a loop.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a configuration method, device and system. Background technique [0002] As a new type of network architecture, SDN (Software Defined Network) is the core of which is the separation of forwarding and control, so as to realize centralized control and quick deployment of the network. Under the SDN architecture, the control plane is moved up to the SDN controller, and SDN devices forward packets according to the instructions of the SDN controller. [0003] The SDN network is divided into access, aggregation and core layers. Due to the large number of SDN access devices, on-site configuration is time-consuming and laborious. Generally, zero-configuration of the network management channel is adopted, and SDN devices can be managed by the SDN controller when they are connected to the SDN network. Wherein, the Dynamic Host Configuration Protocol (DHCP, Dynamic Host Configura...
