Detailed Description
The technical contents of the invention are described in detail below with reference to the accompanying drawings and specific embodiments.
The invention provides a device deployment method, which is suitable for a switch and a deployment node which support iNof specification, wherein the deployment node comprises a first node and a second node, and the first node and the second node communicate through the switch, and the method comprises the following steps:
the switch receives LLDP advertisements of the first node and the second node;
pushing node information to the first node and the second node;
pushing the updated network node information on line to the first node;
receiving an LLDP advertisement set by the second node on the new network;
and pushing the updated information of the first node to the second node.
The deployment node supporting the iNof-ODCC specification registers the node information to a switch supporting the iNof specification in an LLDP (link layer discovery protocol) notification mode, wherein the node information comprises but is not limited to a node IP (Internet protocol) address and an identifier of a node; while the deployment node may obtain the full amount of registration information from the switch. The deployment node subscribes to state notification to the switch, and the switch notifies the deployment node when subsequent network topology changes (access and exit of the network node).
Based on the fast awareness function of the network topology provided by the infrastructure of the iNof-ODCC specification, multiple nodes participating in deployment are discovered. After the node discovery phase is completed, further node configuration may be implemented, thereby completing deployment of the entire system.
In a preferred embodiment of the present invention, the device deployment method may be divided into four stages:
a preparation stage: connecting a network and setting a DHCP server;
a node discovery phase: discovering the nodes participating in deployment through a switch supporting iNof-ODCC specifications;
a network configuration stage: setting a network participating in deployment of nodes;
a software configuration stage: installing and configuring software on the deployment node;
wherein, the detailed operation steps of each stage are as follows:
1. preparation phase
A DHCP server exists on the network;
all the participating deployment nodes are accessed to a switch network supporting the iNof-ODCC specification (the switching network can be composed of one or more interconnected switches supporting the specification);
the network port of the deployment node is set to obtain an IP address through DHCP;
2. node discovery phase
The deployment node comprises a first node and a second node, and the first node is a control node and the second node is an execution node from function classification. The control node is responsible for deployment flow control; the executing node is responsible for executing the deployment action. The processing procedure is shown in figure 1:
and after acquiring the IP address from the DHCP server, the deployment node sends an LLDP (link layer discovery protocol) notice to the switch for registration.
a) The LLDP advertisement sent by the control node comprises a node IP address, a node identifier and a subscription network information change message.
b) The LLDP advertisement sent by the execution node comprises the IP address of the node and the identifier of the node.
The identifier of the node has a specific rule, and in a preferred embodiment of the invention, the node ID is encoded by using vendor information, product information and a node ID, and the node ID has global uniqueness.
And after receiving the LLDP announcement of the deployment node, the switch pushes the full-amount node information of the full network to the deployment node through a state notification message.
The control node receives a state notification message of the deployment node sent by the switch for the first time, traverses and analyzes the registration information of all the deployment nodes, tries to analyze the information including but not limited to manufacturer information, product information and node ID according to a specific composition rule by using identifiers of the deployment nodes, and utilizes the analyzed key information of the deployment nodes, including but not limited to manufacturer information and product information. Through the key information, the control node can screen out the nodes needing to participate in deployment to form a deployment node list.
The aging time of the switch LLDP is defined as 120 seconds, and the period for the deployment node to send the LLDP advertisement is 30 seconds. If the switch does not receive the LLDP advertisement of the deployment node for more than 120 seconds, the switch considers the deployment node to be offline. The switch sends an offline status notification message to the control node.
After the control node is started, the control node receives a deployment node state notification message sent by the switch, and three situations exist. The control node analyzes the second node information carried in the notification message, and performs the following processing:
a) If the second node information content is a node offline type and the second node is in a deployment node list, removing the node from the deployment node list;
b) If the second node information content is of a node offline type and the second node is not in the deployment node list, ignoring the node;
c) And if the second node information content is the node online type, extracting an identifier from the second node information content, and trying to analyze the manufacturer information and the product information. Adding the second node to the deployment node list if the vendor information and the product information match.
The control node can quickly refresh the deployment list by utilizing a mechanism of quickly discovering the node state by the switch, so that the availability of the nodes participating in the deployment before the next stage is ensured as much as possible, and the problem of failure in deployment caused by offline of the nodes in the subsequent deployment process is avoided.
3. Network configuration phase
The deployment operator can query all nodes found to be eligible from the control node. When the nodes needing to participate in the deployment are discovered, the deployment operator implements the network configuration. The processing procedure refers to fig. 2:
and the deployment operator acquires a deployable node list from the control node, configures a network of the deployment node and sends the configuration to the control node, and the control node establishes connection with a deployment agent program of the execution node according to the IP address information recorded in the deployment node list.
The control node configures a new IP address to the executing node. And the deployment agent program on the execution node reconfigures the IP address, and sends a new LLDP notice to the switch after the configuration is successful, so as to update the IP address information registered in the switch.
The switch pushes the registration information after updating the execution node to the control node, the control node receives the network node information sent by the switch, firstly obtains the network identifier, then compares the network identifier with the deployment node in the cache, and if the network identifier is the deployment node, the deployment node information is updated, such as a new IP and the like. And after the deployment nodes of the control node cache are updated, the network configuration stage is completed.
4. Software configuration phase
When the network configuration of all nodes is completed, the software configuration phase can be entered. The processing procedure is as shown in FIG. 3:
and the control node uses the IP address updated by the execution node to reestablish connection with the deployment agent program on the execution node, the control node performs software installation configuration on the execution node and checks the software installation state of the execution node, and after the configuration of all the execution nodes is completed, all the deployment nodes (including the execution node and the control node) stop sending LLDP (link layer discovery protocol) notifications to the switch, and the deployment process is finished.
The present invention has been described in detail. It will be apparent to those skilled in the art that any obvious modifications thereof can be made without departing from the spirit of the invention, which infringes the patent right of the invention and bears the corresponding legal responsibility.
