Embodiment Construction

[0056] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0057] The invention proposes a gateway-based low-cost main-standby hot switching system and method. The network layer of the main-standby hot switching 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, realize that the two sets of communication switching systems simultaneously process the same information synchronously, and generate the same output, thereby ensuring that th...

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 ...
