Example Embodiment

[0056] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0057] The present invention provides a low-cost master-backup hot switch system and method based on a gateway. The network layer of the master-backup hot switch is controlled by the VRRP protocol, and the transmission layer is controlled by the access gateway. The core of the present invention is to ensure that both the main and standby equipment have the same input, so that the two sets of communication exchange systems can simultaneously process the same information and produce the same output, t...

Abstract

The invention provides a low-cost primary/standby hot switching system and method based on gateway. The method comprises the following steps: the first switch equipment and the second switch equipmenthave the same configuration and running state, and communicate with the VRRP equipment through a virtual network interface; the VRRP equipment communicates with the external system equipment throughan external access interface; in the initialization, the roles of the first switch equipment and the second switch equipment are set as the standby equipment, when a voice signaling message from the external system equipment is received through the VRRP equipment, the switch equipment sets its own as the primary equipment; when a synchronization message from the external system equipment is received through the VRRP equipment, the switch equipment sets its own as the standby equipment; the VRRP equipment performs the primary/standby hot switching control of a network layer to realize the virtualization of the network layer, thereby enabling the primary equipment and the standby equipment to only present the virtual network interface for the external. The low-cost primary/standby hot switching system provided by the invention avoids the complex modification at the core network side, realizes the low cost of the design and the realization of the primary/standby hot switching scheme.

Description

technical field [0001] The invention relates to the technical field of communication information, in particular to a gateway-based low-cost main-standby hot switching system and method. Background technique [0002] Most of the existing communication switching systems do not have an active-standby switching design at first, and generally a single set of large-scale switches operate independently. If a sudden disaster occurs, it is very dangerous. Once the large-scale switch fails, all ongoing services will be lost. interruption. Moreover, the switch needs to process a wide variety of information and huge traffic, so redesigning the active / standby switch will involve many aspects and increase the complexity of the large-scale switching system. [0003] In the communication switching system with active / standby switching function, detection modules, synchronization modules and switching modules are added to the switching system to cyclely detect whether the current link is on ...
