Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In the description of embodiments of the present invention, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.
Fig. 1 is a flowchart of an implementation method for determining an online status of a network device according to an embodiment of the present invention.
Referring to fig. 1, the method for determining the online status of the network device according to the embodiment of the present invention may be applied to detecting the online status of the internet of things device in a public cloud, private cloud, home, company or group organization local area network, and may be specifically applied to electronic devices such as a computer, a notebook computer, a personal digital assistant, a PAD, etc.; the method comprises the following steps:
step 101, under the condition that an instruction for detecting the online state of the network equipment is received, acquiring a first IP address set of the network equipment.
Specifically, in the embodiment of the present invention, the detection of the online status of the network device may be an application program in the electronic device. After the application program is started, the testers perform asset entry of the whole network IP equipment, specifically, the IP addresses of all the Internet of things equipment in the local area network are entered, so that a first IP address set corresponding to all the network equipment in the local area network is formed. Specifically, in the embodiment of the present application, under the condition that a probe instruction for starting probing is received, an application program obtains a first IP address set of all network devices in a local area network.
Step 102, calling a function library independently packaged based on ICMP protocol.
The function library comprises configurable detection parameters, and the detection parameters comprise the detection timeout time length.
Specifically, the Internet control message protocol (Internet Control Message Protocol, ICMP) is a sub-protocol of the TCP/IP protocol family 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. Specifically, the overall timeout length of the detection is a delay length for allowing the network device degree detection packets corresponding to all the current IP addresses to answer.
And step 103, according to the detection parameters and the first IP address set, sending a detection packet to the network equipment corresponding to the first IP address set by a sending thread of the function library.
Specifically, in the embodiment of the present invention, the size of the probe packet sent to the network device corresponding to each IP address may be the same, and the unit is Byte.
It should be noted that, in the embodiment of the present application, the probe packet may be sent to all network devices corresponding to the first IP address set at one time through a sending thread of the function library; in some possible examples, the probe packet may be sent with a partial IP address according to actual needs. For example, in some specific examples, the address sets of IPV4, IPV6 may be organized in advance and probe packets may be sent only to network devices corresponding to the address sets of IPV4, IPV 6. This is not particularly limited in the embodiment of the present invention.
Step 104, receiving a response packet of the network device responding to the probe packet at a receiving thread of the function library.
Specifically, in the embodiment of the present invention, the receiving thread and the sending thread of the function library are different threads and may be multiple but at least one of each thread, and after the network device receives the probe packet sent by the sending thread of the function library, the network device responds to the probe packet and returns a response packet. In particular, the reply packet may include an IP address of the corresponding network device and a response time of the network device to respond to the probe packet.
Step 105, judging whether the executed time length of the current detection is greater than or equal to the detection timeout time length.
Specifically, in the embodiment of the present invention, timing may be performed when a probe packet is sent, timing may be performed again when each response packet is received, and then all timings of the received response packets may be accumulated. The accumulated time is the executed time length of the current detection.
And step 106, if the judgment result is yes, determining the online state of the network equipment according to the received response packet.
Specifically, in the embodiment of the present invention, after the accumulated time length is greater than or equal to the probe timeout time length, no matter whether the reply packet can be further received later, the network device that does not respond or returns the reply packet after exceeding the probe timeout time length is regarded as not being online. In a specific example, a probe timeout length of 5s and 1000 network devices are taken as an example for illustration; and within the detection timeout time length of 5s, 800 network devices return response packets, and the other 200 network devices return response packets after exceeding 5s, so that the state of the 200 network devices returning the response packets after exceeding 5s is determined to be offline.
According to the method for determining the online state of the network equipment, the ICMP protocol is used for independently encapsulating the function library, when the online state of the network equipment is detected, the independent encapsulating function library is called, a sending thread in the function library sends detection packets to all network equipment needing detection at one time, and a receiving thread in the function library receives response packets of the network equipment responding to the detection packets; the detection packets are sent by adopting the independent sending threads in the independent packaging function, so that the detection packets can be sent to all network devices in batches at one time without waiting for the response of the network devices, the detection time for detecting the network devices is saved, and the detection efficiency is improved.
Fig. 2 is a flowchart of an implementation of a method for determining a presence status of a network device according to another embodiment of the present invention.
Based on the foregoing embodiments, referring to fig. 2, a method for determining an online status of a network device according to another embodiment of the present invention includes the following steps:
step 201, based on ICMP protocol, the function library is independently packaged.
Wherein the independently packaged function library comprises at least one of the following configurable probing parameters: detecting a first IP address set, the number of sending threads, the number of receiving threads, the time interval for sending the detection packet, the first times for sending the detection packet aiming at the same IP address, the detection timeout time length and the detection packet size.
Step 202, under the condition that a configuration instruction for the number of sending threads is received, configuring the number of the sending threads of the probing of the independent encapsulation function library.
Specifically, in the embodiment of the present invention, before detecting the network device, the number of sending threads and the number of receiving threads of the encapsulation function library may be configured; specifically, the number of sending threads and the number of receiving threads may be determined according to the number of network devices, the resource occupancy rate of a central processing unit (central processing unit, CPU) of the probe device, and the like.
Step 203, acquiring a first IP address set of the network device when a detection instruction for detecting the online state of the network device is received.
Step 204, calling a function library independently packaged based on ICMP protocol.
Step 205, dividing the first IP address set equally according to the number of the sending threads to obtain a plurality of second IP address sets equally, and simultaneously, assigning a unique sending thread to each second IP address set.
Specifically, in the present embodiment, the number of transmission threads is p, and Sn IP addresses in the first IP address set are taken as an example, and the second IP address set sr=sn/p.
And 206, transmitting the probe packet to the network equipment corresponding to the corresponding second IP address set at the specified unique transmission thread of the function library.
In the embodiment of the application, the plurality of sending threads are established, the first IP address set is split equally through the plurality of sending threads, and the detection packet is sent to the network device corresponding to the second IP address set in an equal amount in each sending thread, so that the sending efficiency of the detection packet is further improved, and the detection requirement for detecting network devices in a larger order of magnitude, such as millions, can be met.
Step 207, receiving, at a receiving thread of the function library, a reply packet of the network device responding to the probe packet.
Specifically, when the receiving thread receives the response packet, the IP address corresponding to the response packet and the response time of the IP address are recorded.
Step 208, determining whether the executed time length of the current detection is greater than or equal to the detection timeout time length.
Step 209, if the determination result is yes, determining the online state of the network device according to the received response packet.
In some optional implementations, the method for detecting the online status of the network device provided by the embodiment of the present invention further includes:
and under the condition that a configuration instruction for transmitting the first number of the probe packets for the same IP address is received, configuring the independent encapsulation function library to transmit the first number of the probe packets for each IP address.
Specifically, the network device corresponding to the same IP address may perform one-time detection or may perform multiple-time detection. When the number of probing for the same IP address is configured, the time interval of each probing, that is, the length of time interval for transmitting the probing packet to the same IP address may be also configured. In the embodiment of the invention, the specific length of the interval time is not limited.
And judging whether the second times of sending the detection packet aiming at the network equipment corresponding to the current IP address is smaller than the first times.
And if the judgment result is yes, determining whether the network equipment corresponding to the current IP address responds to the detection packet according to the response packet received by the receiving thread.
Specifically, when the number of times of sending the probe packet to the network device corresponding to a certain IP address is smaller than the first number of times, it may be first determined whether the IP address receiving thread receives the response packet responding to the IP address, and if the IP address has responded to the probe packet, the probe packet does not need to be sent to the IP address again, thereby greatly reducing the number of IP addresses for sending the probe packet again and improving the probe efficiency.
And under the condition that the network equipment corresponding to the current IP address does not respond to the detection packet, continuing to send the detection packet to the network equipment corresponding to the current IP address by the sending thread until the second time is equal to the first time.
Specifically, after the number of times of sending the probe packet to a certain IP address is equal to the first number of times, if a response packet of the IP address to the response of the probe packet is still not received, it is confirmed that the online state of the network device corresponding to the IP address is not online.
In some alternative examples, after receiving the reply packet, presence identification information may be added to the IP address to which the reply packet corresponds, where the presence identification information may include "1", "0", etc., where "1" may indicate presence and "0" may indicate absence. In some possible examples, the presence status identifying information may also be "Y", "N", where "Y" indicates presence and "N" indicates absence of presence.
In some possible examples, the method for determining the online status of a network device according to the embodiments of the present invention may further include configuring a time interval for sending a probe packet for each IP address, where the time interval may be configured according to actual needs, for example, 1ms, 3ms, 5ms, and so on; where 0ms is denoted as continuous transmission.
