Background
ICMP (Internet Control Message Protocol) is an Internet control message protocol, a connectionless-oriented protocol, a sub-protocol of the TCP/IP protocol suite for passing control messages between IP hosts and routers. The control message refers to a message of the network itself such as a network is not connected, whether a host is reachable, whether a route is available, and the like. These control messages, although not transmitting user data, play an important role in the transfer of user data.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is a flowchart of a storage network detection method according to an embodiment of the invention. The method may include:
step 101: acquiring an IP to be detected; wherein the number of IPs to be detected is greater than or equal to 2.
The IP to be detected in this step may be an IP address where occupancy detection is currently required.
Specifically, for the specific mode of acquiring the IP to be detected by the processor in the step, the specific mode can be set by a designer according to a practical scene and user requirements, for example, the processor can directly take the IP address set by the user as the IP to be detected; the preset number of IP addresses can also be selected from the plurality of IP addresses to serve as the IP to be detected, for example, in the step, the processor can acquire an IP detection task; selecting a preset number of to-be-detected IPs from the IP detection tasks by using producer consumers and a priority queue model; wherein each IP detection task comprises a respective corresponding IP. The present embodiment does not impose any limitation on this.
Correspondingly, for the processor, a specific mode of selecting a preset number of to-be-detected IPs from the IP detection tasks by using the producer consumer and the priority queue model can be set by a designer, for example, the producer consumer and the priority queue model can insert a network detection task (i.e., an IP detection task) of a certain IP into the task queue through the producer; the task queue may contain fields such as IP, type, and priority of each network detection task; and the consumer acquires a preset number (1024) of IP (i.e. IP to be detected) in the task queue according to the custom priority rule. That is, the processor may add the IP detection task to the task queue; according to the preset priority rule, a preset number of to-be-detected IPs are selected from the task queue, for example, when the preset priority rule is for the IP priority detection of the preset network segment, the processor may preferentially select the IP of the preset network segment from the IP detection task of the task queue until the preset number of IPs are selected as the to-be-detected IPs.
Step 102: and creating ICMP messages corresponding to each IP to be detected.
The ICMP message in this step may be an ICMP protocol message, that is, a message based on the ICMP protocol for detecting whether the network is available.
Specifically, the specific manner of creating the ICMP message corresponding to each IP to be detected in this step may be set by a designer, for example, may be implemented in the same manner or in a similar manner to the message generation method of the ICMP protocol in the prior art, which is not limited in this embodiment.
Step 103: and sending ICMP messages to the target hosts corresponding to the IPs to be detected in a parallel mode, and determining the occupation condition of the IPs to be detected according to the returned messages of the ICMP messages.
It can be understood that the target host in this step may be a host corresponding to the IP to be detected. The purpose of this step may be that the processor sends ICMP messages to multiple target hosts in a parallel manner, and monitors the messages corresponding to the ICMP messages returned by the target hosts (i.e., return messages), so as to quickly and efficiently determine reachability of multiple target hosts, that is, occupation conditions of the IP to be detected are occupied when the target host corresponding to the IP to be detected is reachable; and when the target host corresponding to the IP to be detected is not reachable, the occupation condition of the IP to be detected is unoccupied.
Specifically, in this embodiment, the occupation condition of a plurality of IPs to be detected is monitored in a parallel manner, which is more efficient than a serial monitoring manner. For the processor in this step, an ICMP message is sent to the target host corresponding to each IP to be detected in a parallel manner, and a specific manner of determining the occupation situation of the IP to be detected according to the return message of the ICMP message may be set by a designer, for example, the processor may implement detection of the occupation situation of the IP to be detected based on multiple threads, for example, when the occupation situations of N IPs to be detected need to be detected in this step, as shown in fig. 2, the processor running the multi-device storage management software may create N threads; each thread is utilized to monitor the return message of the ICMP message returned by a corresponding host (namely the target host); after all threads are finished, determining the occupation condition of N to-be-detected IPs. In order to avoid the resource consumption caused by the thread opening and thread switching, in this step, the processor may adopt an asynchronous IO (input/output) manner to implement the detection of the occupation condition of the IP to be detected, for example, based on the IO multiplexing model, send ICMP messages to the target hosts corresponding to the IPs to be detected in a parallel manner, and determine the occupation condition of the IPs to be detected according to the return messages of the ICMP messages. The present embodiment is not limited in this regard.
Specifically, the IO multiplexing model can be established on the basis of a multiplexing function selection provided by the kernel, and the problem of polling waiting in the synchronous non-blocking IO model can be avoided by using the selection function; the principle can be as follows: firstly, adding a socket needing IO operation into a select by a user, and then blocking to wait for return of the select system call; when the data arrives, the socket is activated and the select function returns; the user thread formally initiates a read request, reads the data and continues execution. A user can register a plurality of sockets and then continuously call the select to read the activated sockets, so that the aim of simultaneously processing a plurality of IO requests in the same thread can be fulfilled.
Correspondingly, the embodiment does not limit the specific manner that the processor sends ICMP messages to the target hosts corresponding to the IPs to be detected in a parallel manner based on the IO multiplexing model, and determines the occupation condition of the IPs to be detected according to the return messages of the ICMP messages, as shown in fig. 3, and may include:
step 201: and creating a pipeline corresponding to each IP to be detected and acquiring a file descriptor corresponding to each IP to be detected.
In this step, the pipe may be used to send a channel (socket) of an ICMP packet corresponding to the IP to be detected; in the step, the file descriptors corresponding to each pipeline can be acquired, so that the read operation of the file descriptors is monitored, and the return condition of the return message of the ICMP message is determined; as shown in fig. 4, when the number of IPs to be detected is N, N pipes may be created, N file descriptors corresponding to the N pipes respectively are acquired, and the read operations of the file descriptors are specified to be monitored.
Step 202: and sending the ICMP message to the target host through the pipeline.
Specifically, the purpose of this step may be that the processor sends, through the created pipe (socket) corresponding to each IP to be detected, a corresponding ICMP packet to the target host corresponding to each IP to be detected.
Step 203: polling to detect a target file descriptor in the file descriptors; wherein the target file descriptor is a readable file descriptor.
It will be appreciated that the purpose of this step may be for the processor to determine the target host of the return message that returned the ICMP message by polling for a file descriptor readable in the file descriptor (i.e., the target file descriptor). That is, if the target host corresponding to the IP to be detected returns a return message of the ICMP message, a read operation will occur on the file descriptor corresponding to the IP to be detected, that is, the file descriptor is readable.
Specifically, for the specific mode of polling and detecting the target file descriptor in the file descriptor by the processor in the step, the method can be set by a designer, for example, the poll function can be utilized to poll and detect the target file descriptor in the file descriptor; as shown in fig. 4, the poll function can be used to monitor whether the file descriptor set is readable; and determining the target file descriptor according to the return value of the poll function so as to judge the occurrence of the readable event of the pipeline.
It should be noted that, in this embodiment, the training time of the file descriptor may be set, that is, the timing may be performed when the polling detection of the target file descriptor in the file descriptor is started, and whether the timing time reaches the training time may be determined; if the training time is reached, determining that the occupation condition of the IP to be detected corresponding to the non-target file descriptor in the file descriptors is unoccupied.
Step 204: and determining the occupation condition of the IP to be detected corresponding to the target file descriptor according to the returned message of the ICMP message corresponding to the target file descriptor.
It can be understood that the purpose of this step may be to determine, according to a return message of an ICMP message on a pipeline corresponding to a readable file descriptor (i.e., a target file descriptor), an occupancy condition of an IP to be detected corresponding to the file descriptor, where, if the return message of the ICMP message corresponding to the target file descriptor is a normal message returned by a target host, it may be determined that the target host is reachable, that is, the occupancy condition of the IP to be detected corresponding to the file descriptor is occupied.
Specifically, the processor in this step may determine whether the return message of the ICMP message corresponding to the target file descriptor is a normal message returned by the target host; if yes, determining that the occupied condition of the IP to be detected corresponding to the target file descriptor is occupied; if not, determining that the occupation condition of the IP to be detected corresponding to the target file descriptor is unoccupied.
In this embodiment, in the embodiment of the present invention, by sending an ICMP packet to a target host corresponding to each IP to be detected in a parallel manner, and determining an occupation condition of the IP to be detected according to a return packet of the ICMP packet, the ICMP packet can be sent to multiple target hosts in a parallel manner based on the ICMP protocol, so as to quickly and efficiently determine reachability of multiple target hosts, that is, determine occupation conditions of multiple IP to be detected, so that multiple device storage management software can quickly and conveniently detect unoccupied IP addresses in a management network, and improve availability and usability of the multiple device storage management software.
