Abstract
The invention provides a method for rapidly detecting connection states and making a virtual machine HA. Connection between a server and a client is rapidly detected to judge whether the connection is valid, and if the connection is invalid, the virtual machine in a physical machine at the client is restarted in In-Clouds OS. A system comprises a heartbeat detection module and an action processing module, wherein the heartbeat detection module is responsible for communicating with a client agent, and the action processing module is an ultimate objective of a scheme provided in the invention and is responsible for corresponding processing when the connection is invalid including operation of the virtual machine HA. The operation of the virtual machine comprises the steps that: server maintains connection between the client and the server itself,, and the client is requested to respond through the connection to sent a signal to the other side; if a plurality of signals are sent out with no response, the connection is judged to be interrupted, and the virtual machine in the physical machine at the client is restarted in the In-Clouds OS when the connection is interrupted.
Description
Technical field
The present invention relates to fields such as virtual, cloud computing, be specifically related to a kind of fast detecting connection status and do the method for virtual machine HA.
Background technology
Traditional server based on the TCP connected reference is used, and after the user accomplishes the operation that he carries out, bumps or the electricity went off if give netting twine because of carelessness; This TCP connects and has broken off in fact, but server and not knowing is also safeguarded this connection; Do not loose but also before will waiting for this connects certain hour, just go to inquire about this connection status, through repeatedly attempting back (yet free interval between each the trial); If still not response; Then judge to connect and interrupt, well imagine that this cycle can be very long.
And that a kind of fast detecting connection status and the method for being virtual machine HA realize that general test connects the time interval of whether interrupting adopting is all shorter, and whether decision that can be very fast connects interrupts.And, owing to be to realize in application layer, because can decide the behavior of having no progeny and take in the connection in its sole discretion when judging.So just being embedded among the sea of clouds OS easily, this method goes.
Summary of the invention
The purpose of this invention is to provide a kind of fast detecting connection status and do the method for virtual machine HA.
The objective of the invention is to realize by following mode; Through the whether also survival that is connected between fast detecting server end and client, lost efficacy if connect, then in sea of clouds OS; Restart the virtual machine on the client physical machine; System comprises: the heartbeat detection module, and the action processing module, wherein:
The heartbeat detection module: be responsible for client agent between communicate by letter;
Action processing module: be the final purpose of this scheme, be responsible for, comprise virtual machine HA operation in the handled that connected after losing efficacy;
Operating procedure is following:
Server end guardian client is connected with oneself; And respond through this connection request client; Send a signal and give the other side, all do not have response, then judge to connect and interrupt if repeatedly send signal; When connect interrupting, then in sea of clouds OS, restart the virtual machine on the client physical machine.
The invention has the beneficial effects as follows: it is all shorter to realize that general test connects the time interval of whether interrupting adopting, and whether decision that can be very fast connects interrupts.And, owing to be to realize in application layer, because can decide the behavior of having no progeny and take in the connection in its sole discretion when judging.So just being embedded among the sea of clouds OS easily, this method goes.
Description of drawings
Accompanying drawing 1 is a kind of fast detecting connection status and the sketch map of doing the method for virtual machine HA.
Embodiment
Explanation at length below with reference to Figure of description method of the present invention being done.
Through the whether also survival that is connected between fast detecting server end and client, lost efficacy if connect, then in sea of clouds OS, restart the virtual machine on the client physical machine, system comprises: the heartbeat detection module, the action processing module, wherein:
Wherein, the heartbeat detection module: be the core of whole architectural framework, be responsible for to detect with client between be connected;
The action processing module: be responsible for client and connected when losing efficacy, corresponding action is handled, and comprises the release of connection resource, the restarting etc. of virtual machine.
Fast detecting connection status of the present invention is also done the method for virtual machine HA, and implementation step is described below: in sea of clouds OS, embed the heartbeat detection module, all the other client-servers are disposed agent application proxies; The detection of response heartbeat module; Assay intervals can define voluntarily, and the data segment of transmission briefly gets final product as far as possible, sends continuously; If the detection that continues to connect does not several times meet with a response; Think then to connect and interrupt that server possibly go wrong by network, then need do corresponding processing to the virtual machine on the server.Corresponding handle the release that comprises connection resource, in sea of clouds OS, restart restarting of virtual machine virtual machine on the client physical machine etc.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. a fast detecting connection status and do the method for virtual machine HA; It is characterized in that losing efficacy if connect, then in sea of clouds OS through the whether also survival that is connected between fast detecting server end and client; Restart the virtual machine on the client physical machine; System comprises: the heartbeat detection module, and the action processing module, wherein:
The heartbeat detection module: be responsible for client agent between communicate by letter;
Action processing module: be the final purpose of this scheme, be responsible for, comprise virtual machine HA operation in the handled that connected after losing efficacy;
Operating procedure is following:
Server end guardian client is connected with oneself; And respond through this connection request client; Send a signal and give the other side, all do not have response, then judge to connect and interrupt if repeatedly send signal; When connect interrupting, then in sea of clouds OS, restart the virtual machine on the client physical machine.
