The accompanying drawing explanation
Fig. 1 is according to a kind of virtual communication link integrality method for supervising principle flow chart of the present invention.
Embodiment
Link attribute, can be known, and except basic link configuration, can also carry out the customization of link attribute, and link attribute is open, as can be carried out the customization of link attribute according to the network of oneself by the dladm order.
Link attribute comprises public attribute and special attribute, the former can be applicable to any driver of given media type, the auto negotiation of link-speeds, Ethernet for example, or can be applicable to the MTU(Maximum Transmission Unit of all drivers of link, MTU) size.For special attribute, be the NIC(Network Interface Card that only belongs to given media type, network adapter, be called for short network interface card) particular subset of driver.These attributes may be specific to this subset, because the hardware that they are associated with driver is closely related, or closely related to the details (as the adjustable parameter relevant with debugging) of driver realization itself.
Link attribute has default setting usually.But, under some network condition, may need the user to change the particular community setting of data link.These setup of attributes can be public or special attributes.For example, NIC may change planes and communicate with the old acquaintance that can not correctly carry out auto negotiation.Perhaps, a switch may be configured to support jumbo frame.Perhaps, may revise the driver particular community received for controlling data packet transmission or packet for given driver.In Oracle Solaris, now can be by single management instrument dladm all these settings of resetting.
Link attribute comprises a lot of contents, can meet the various application of current network.
With reference to Figure of description 1 virtual communication link integrality method for supervising, concrete implementation step is as follows:
At first be the configuration about the virtual link attribute, the default configuration of link attribute can meet the demands usually, but, for specific application, for the degree of opening of link attribute, can specifically arrange, under the nature default setting, in link attribute, also can comprise abnormal information.
And then configuration information collection module, by virtual link client, service end and other correlation module, collect the self attributes of virtual link, as connection status, mapping relations, response performance etc.; The scope gathered information comprises: the virtual link of having set up, each service end can be used for setting up the peripheral hardware of virtual link, registered virtual link client etc.
The concrete methods of realizing gathered information is: after virtual link is set up, service end and client regularly heartbeat detection formula method send self attributes information to the information search module, or attribute status initiatively sends self attributes information to the information search module while changing, or the method initiatively traveled through by the information search module detects registered virtual link, collect module information is stored in this locality (internal storage data structure or database).The communication means that wherein adopted is synchronous or asynchronous message transfer mechanism (as AMQ or JMS).
As heartbeat detects, based on heartbeat mechanism, the reception in network and transmission data are all to use the SOCKET in WINDOWS to be realized.But if this socket disconnects, that just necessarily has problem when sending data and receiving data.Do you how to judge that this socket can also be used? this just need to create heartbeat mechanism in system.In fact in TCP, for us, realized a mechanism that is called heartbeat.If the operator is provided with heartbeat, the heartbeat (such as 2 times) that TCP will the number of times that transmit operation person arranges within the regular hour (what arrange such as the operator was 3 seconds), and this information can not affect the agreement that operator oneself defines.So-called " heartbeat " is exactly self-defining structure of timed sending (heartbeat packet or heartbeat frame), allows the other side know oneself " online ".To guarantee the validity of link.Can obtain heartbeat packet or heartbeat frame by said method, obtain accordingly relevant link information.
By the traversal mode, although the resource consumed is many, can not produce mistakes and omissions.
And the processing method when changing as attribute status, the processing that can be correlated with targetedly, the resource taken compares less.
Further, the configuration data analysis module, to the information of the collecting analysis-by-synthesis of being classified, statistics/screening is for feeding back to the information of virtual link client and service end, and to these information classifications processing (as normal, warning, fault etc.); Also can be analyzed the assembly that does not form temporarily virtual link.
Concrete methods of realizing is: the storage medium of collecting based on the information search module (internal storage data structure or database), and the strategy arranged by user interface or configuration file, operating state or the performance class of judgement virtual link, to initiatively to other Executive Module (comprising the abnormality processing module), send judgement information and necessary virtual link attribute information by message mechanism, or directly to the abnormality processing module, send the execution instruction.Wherein strategy exists with the form of file or database table; The information and instruction wherein sent to the abnormality processing module, comprise the information and instruction that certain virtual link self is relevant, also comprises the relative and instruction of the information about other link.
And then arrangement abnormalities processing module, generally the distributed inside modules such as virtual link client, service end, control switch that are built in, do corresponding reaction in reception or after obtaining link information, as show each virtual unit connection status, fault prompting, releasing resource etc.
Concrete methods of realizing is: after receiving the link information or instruction that data analysis module sends, simulate link working state on display unit by software, or reminded by modes such as instruction lamp, sound, SMS, mails, or automatically carry out the abnormality processing passage and processed (as the active releasing resource).
