Embodiment Construction
[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0059] 1. Commonly used network layer detection technologies mainly include traditional network topology discovery methods, most of which use SNMP and ICMP protocols. These two detection methods are described in detail below.
[0060] 1. Using the SNMP protocol to build a network topology is a relatively common method at present. By operating the MIB library of the managed device, the available information is extracted to construct a topology. This method has high discovery efficiency and is easy to implement, but because this method needs to traverse the routing tables of all routers in the ...

The invention provides a node state detection method and device for a payment system. The method comprises the following steps: determining a first time length of a first node from the time of sendinga state detection request message to a second node to the time of receiving a detection response message from the second node every first preset time interval; comparing the first time length with apreset second time length, and determining the state of the first node according to a comparison result; and determining the state of the second node according to the detection response message. According to the above technical scheme, the state of each node of the payment system can be detected securely, quickly and reliably, and thus a high-availability routing channel selection can be providedfor message sending, the quick, secure and reliable message transmission of the payment system can be guaranteed, a necessary prerequisite for the stable operation of national second-generation payment systems can be provided, and the very great significance can be achieved.
Description
technical field [0001] The invention relates to the technical field of payment systems, in particular to a method and device for detecting node states of a payment system. Background technique [0002] The Payment Message Transfer System (PMTS), as the supporting system of the national second-generation payment system, is responsible for message communication between the payment system, participants, and various nodes within the payment system. Ensuring fast, safe and reliable message transmission between payment systems is a necessary prerequisite for ensuring the stable operation of the national second-generation payment system. In message transmission, the most critical thing is to determine which node in the system the message is sent to and which remote queue of the node to use. This series of selections and judgments are based on the results obtained by the detection mechanism. Through detection, it can be determined whether the status of adjacent nodes is valid, judg...
