Embodiment Construction

[0034] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] In this embodiment, a controller replacement method is provided, figure 1 is the flow of the controller replacement method according to the embodiment of the present invention Figure 1 ,Such as figure 1 As shown, the process includes the following steps:

[0036] Step S102, sending a first message to the first single-domain controller;

[0037] Step S104, judging whether a response message returned by the first single-domain controller according to the first message is received within the first predetermined time;

[0038] Step S106, if the judgment result is negative, perform replacement processing of replacing the first single-domain controller with the second single-domain controller i...

Abstract

The invention provides a controller replacement method and a controller replacement device, wherein the controller replacement method comprises the steps of transmitting a first message to a first single domain controller; determining a response message which is returned from the first single domain controller according to the first message in a first preset time period; and on condition that the determining result is no, performing replacement processing of replacing the first single domain controller by a second single domain controller in a main multi-domain controller. The controller replacement method and the controller replacement device settle a problem of low resource utilization rate caused by standby controller replacement in the same level in settling controller faults in related technology, and furthermore realize effects of improving resource utilization rate and improving system stability.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for replacing a controller. Background technique [0002] With the rapid development of network technology, software-defined network (Software Defined Network, referred to as SDN) has become a hot spot and focus of research in the industry in recent years. Through the separation of control and forwarding in SDN, the control function is centralized on the controller (Controllor). A centralized and unified controller manages the network within this range, which solves the problem of scattered and independent operation and management of a large number of forwarding devices in the network, and eliminates the differences in the underlying network. There are multiple controllers in a large-scale network. Using a main controller to centrally control many controllers can make the system more stable. The interaction between controllers is completely managed by the co...
