Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0023] This method is specifically the following steps:
[0024] Step 1. Establish a computer network without a central node. There are k nodes in the network, and each node is sequentially numbered, denoted as P 1 ~P k , each node stores a node state table, where the node state table records the node states of all nodes;
[0025] In practical applications, the node state table can be established in the form of a two-dimensional table, and each table item is created with the node number. The content stored in each table item includes the IP address and the power-on / off status, and the node number is the only one of the table item. Index item, that is, the node status can be searched through the node number.
[0026] According to the on / off state of the nodes recorded in the node state table, the nodes in the power-on state are marked as the power-on nod...

The invention discloses a node state rapid monitoring method for a network without a center, and belongs to the field of computer networks. The basic idea of the method comprises the steps that firstly a computer network without a center node is established, the network totally has k nodes from P1 to Pk, and a node state list is stored in each node; then in a current monitoring cycle, each starting node sends a state monitoring packet to a next starting node; if a starting node Pi does not receive a state monitoring packet for continuous m monitoring cycles, the former starting node of the Pi faults, and the Pi updates the node state list and broadcasts a state update packet; if any shut-down node Pj accesses the network when starting up occurs, the Pj sends a state monitoring packet to a next starting node; after the next starting node of the Pj receives the state monitoring packet, the node state list is updated, the state update packet is broadcast, and the starting nodes update the node state list after receiving the state update packets. The node state rapid monitoring method is suitable for the node state monitoring of the network without the center.
Description
technical field [0001] The invention relates to a fast monitoring method for a node state of a centerless network, which belongs to the field of computer networks and is suitable for a computer network without a center node, especially for a centerless network for parallel processing applications. Background technique [0002] In the existing computer network technology field, there are two main network architectures used in parallel processing applications: one is a computer cluster network, and the other is a computer network without a central node, that is, a decentralized network. [0003] The computer cluster network includes cluster management nodes and cluster computing nodes, which are network nodes with different purposes. The main function of the cluster management node is to allocate and manage the user accounts and permissions of the cluster system. In actual applications, the cluster management node usually installs cluster management software, and acts as the m...
