Message sorting mechanism under host overlay

Abstract

The invention provides a message sorting mechanism under a host overlay, which comprises the following steps of: 1, receiving a message under the overlay by a host, analyzing message data, identifying message content, generating a message header and a message body, and generating a session identifier through the message header; step 2, the controller accumulates the session identifier values generated by the message, and the net-agent service records the session identifiers after receiving the message; 3, further identifying and judging the session identifier; and 4, recording an index of the issued data, and executing a corresponding command on the processed configuration message. According to the method, verification is carried out at the sending end and the receiving end by using an algorithm, the transmitted message is further determined, accurate transmission of the message is better ensured, the message is issued through two paths, sequential execution of the message is ensured, and the efficiency is improved. According to the invention, even in a scene of large-scale deployment of virtual machine physical servers, the sequence of messages can still be ensured under the condition of passing through different data sources.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a message sorting mechanism under a host overlay. Background technique [0002] In the current host overlay product, each virtual machine physical server runs the net-agent service, and when a virtual machine goes online or offline, all net-agent services must be notified, and the controller will report to the net agent through two mechanisms. -Agent sends messages. At this time, messages that guarantee logic dependencies must be queued for execution. Out-of-order cannot occur. Once out of order, message execution will fail. Due to the interaction between the controller and net-agent, it may be through the Redis broadcast mechanism , it is also possible to send request data through http. For net-agent, there will be asynchronous messages. In terms of timing, there is a probability that the http request arrives first and the Redis message arrives later, resulting in a pr...

[0002] In the current host overlay product, each virtual machine physical server runs the net-agent service, and when a virtual machine goes online or offline, all net-agent services must be notified, and the controller will use two mechanisms to report to the net-agent service respectively. -Agent sends messages. At this time, messages that guarantee logic dependencies must be queued for execution. Out-of-order cannot occur. Once out of order, message execution will fail. Due to the interaction between the controller and net-agent, it may be through the Redis broadcast mechanism , it is also possible to send request data through http. For net-agent, there will be asynchronous messages. In terms of timing, there is a probability that the http request will arrive first and the Redis message will arrive later, resulting in a processing flow that depends on the context. problem, causing the program flow to go wrong
