With the development of network technology, people can easily access to the internet through any intelligent device at any place covering network signals, and the network signal transmitting device cannot be realized only by a single network signal transmitting device, so that the signal transmitting device such as a router and a switch is greatly utilized in practice. The network constructed in a certain range, except the most basic server, is the most important one is the switch.
A switch is a network device for electrical (optical) signal forwarding that provides an exclusive electrical signal path for any two network nodes accessing the switch. The traditional switch has complete and relatively independent functions, namely the traditional switch can complete the configuration of parameters and carry out subsequent work by the traditional switch, but the efficiency is seriously reduced due to the one-to-one configuration along with the increase of the number of the switches, so that a novel thin switch appears. The thin switches do not work and configure independently, but are managed and configured uniformly by an upper network Controller (Net Access Controller, abbreviated as AC), so the thin switches must be used together with the AC.
In the prior art, when a switch is newly added, the position and configuration information of the newly added switch need to be marked on a topological graph in advance, then activation is completed on an AC at first, the newly added switch is actually accessed to a corresponding position in a network, and finally the configuration information configured at first can be obtained to complete the deployment of the newly added switch. Similar steps are needed to modify the configuration information of one switch, because all the switches at all the layers need to acquire the configuration information from the AC to complete the deployment in the network, the switches at the second layer, the third layer and even deeper layers need to be forwarded layer by layer, the steps are very complex, the consumed time is more, and the use effect in the network with more layers and complex connection relationship is not good.
Therefore, how to overcome various technical defects of the existing switch deployment scheme and provide a switch deployment method with fewer steps, more time consumption, better use effect in a network with more layers and complex connection relationship is a problem to be solved urgently by technical personnel in the field.

Detailed Description
The core of the application is to provide a method, a system, a device and a computer readable storage medium for rapidly deploying switches, wherein a whole network topological graph containing position structure information of all switches and corresponding configuration information is issued to one switch, after deployment is completed by using the information contained in the whole network topological graph, the whole network topological graph is issued to all connected other switches as a root switch, and when one other switch completes deployment, the whole network topological graph is continuously and repeatedly issued as a new root switch until all switches in a network are completely deployed. Because the topology map of the whole network carries the switch information corresponding to all layers and positions, the switch information can be obtained only from the recently connected switches, and as the number of layers increases, the number of switches which become a new root switch to execute the issuing operation increases, and the deployment of the whole network switches can be completed quickly in a virus mode.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a method for rapidly deploying a switch according to an embodiment of the present application.
The method specifically comprises the following steps:
s101: acquiring a whole network topological graph which is obtained based on the drawn and acquired technology and contains the deployment relation of all switches in the network and the configuration information required by all the switches on line, and storing the topological graph on an AC;
the method is characterized in that the whole network topological graph containing configuration information required by the online of each switch is obtained, and the method is different from the traditional mode of collecting network construction information and drawing to obtain the whole network topological graph. In brief, the switch configuration mode of the original table format is changed into an intuitive topology, and each point in the topology can be intuitively and directly changed into the configuration.
In general, before the whole network is constructed, the topology map of the whole network can be obtained according to the design requirements of customers, and only the configuration information required by the switches corresponding to the preset positions of the online line needs to be added.
S102: issuing a topology graph of the whole network to a root switch, and finishing the deployment of the root switch by using the contained configuration information; wherein, the root switch is a switch with the first switch accessing the AC;
on the basis of S101, this step is intended to issue the generated entire network topology map to the first switch accessing the AC, and since the switch is the first switch accessing the AC, and the other switches on the same layer and lower layers will also implement issuing the entire network topology map by means of the switch, the switch may be referred to as a root switch, that is, the first switch accessing the AC is referred to as a root switch.
After the topology map of the whole network is sent to the root switch, the root switch can acquire the configuration information corresponding to the position of the root switch from the topology map of the whole network, and complete the deployment of the root switch according to the configuration information.
S103: after the root switch is deployed, issuing a topology graph of the whole network to all other switches connected with the root switch so as to enable all other switches to complete deployment according to the configuration information;
the step is established on the basis that the root switch completes deployment according to the whole network topological graph issued by the AC, and aims to issue the whole network topological graph to all other switches establishing connection relations with the root switch by the root switch, so that all other switches establishing connection relations with the root switch can also realize self deployment according to the received whole network topological graph. The other switches specifically include a same-layer switch in the same layer as the root switch and a lower-layer switch located below the root switch.
Specifically, how to implement how to issue the entire network topology map to the other switches by the root switch is various, and in general, a data transmission channel may be determined from the connection relationship and the corresponding communication port included in the topology map, so as to transmit data through the data transmission channel, and finally, the other switches complete deployment according to the received data (the entire network topology map).
Further, before the entire network topology is sent to all other switches connected to the root switch, in order to prevent the switches from storing the configuration information of the previous shutdown port to cause a subsequent error, an initialization operation may be performed on the switches to clear unnecessary configuration information.
S104: and when any other switch is deployed, the switch becomes a new root switch, and a whole network topology map is issued to all switches connected with the new root switch until all switches in the network are deployed.
The step is established on the basis that the deployment of other switches is completed according to the whole network topological graph issued by the root switch, when the other switches which are connected with the root switch complete the self deployment according to the whole network topological graph issued by the root switch, the other switches become new root switches as the root switch which is connected with the AC at the beginning, and continue to issue the whole network topological graph to all the switches which are connected with the new root switch according to the same mode until all the switches in the network complete the deployment.
Further, according to the switch deployment method provided by the application, even when a certain switch is offline on the network due to configuration abnormality (IP, routing, Vlan, etc.), forwarding of the updated configuration information can be completed by other switches of the same layer connected to the certain switch, so that the offline switch is finally brought online again according to the received updated configuration information. The reason is that each switch stores the whole network topological graph, so that the switch connected with the switch can be determined according to the whole network topological graph, and all configuration information of other switches is also included, so that the off-line switch caused by configuration abnormality can be remotely repaired in such a way, and the switch is not required to be repaired by being connected with a corresponding serial port on site.
The switch deployment mode provided by the application is similar to chain reaction and cell division in principle, and the similar point is that the switch deployment mode can be propagated and 'propagated' in a virus mode.
Based on the above technical solution, the method for rapidly deploying switches provided in the embodiments of the present application issues a whole network topology map including position structure information of all switches and corresponding configuration information to one switch, and after deployment is completed by using information included in the whole network topology map, the whole network topology map is issued to all connected other switches as a root switch, and when one other switch completes deployment, the whole network topology map is continuously issued as a new root switch repeatedly until all switches in a network are completely deployed. Because the topology map of the whole network carries the switch information corresponding to all layers and positions, the switch information can be obtained only from the recently connected switches, and as the number of layers increases, the number of switches which become a new root switch to execute the issuing operation increases, and the deployment of the whole network switches can be completed quickly in a virus mode.
With reference to fig. 2, fig. 2 is a flowchart of a method for issuing an entire network topology and deploying a root switch in a method for deploying switches quickly according to an embodiment of the present application.
The method specifically comprises the following steps:
s201: determining all other switches connected with the root switch according to the topology map of the whole network, and determining corresponding communication ports;
s202: and issuing the whole network topological graph to other corresponding switches by using the communication port so that the other switches complete the deployment according to the configuration information.
For the step S202, a more practical specific operation step is given:
step 1: broadcasting SSPDU notification messages to other corresponding switches through a communication port by utilizing an SSPDU communication protocol;
step 2: when other switches receive the SSPDU notification message, the STP is opened, and an ACK signal is returned to the root switch;
and step 3: the root switch sends the topology map of the whole network to other switches which send ACK signals through communication ports;
and 4, step 4: and other switches complete deployment according to the received configuration information contained in the topology map of the whole network.
The SSPDU communication Protocol used herein is a private two-layer communication Protocol, which is called a sun Switch Protocol Data Unit, and is used for communication between two switches, and has the characteristics of cross-Vlan propagation and capability of penetrating a blocking port, and the Switch does not forward the packet, and the Switch that needs to be used in a supporting manner can support the private communication Protocol; STP is called as Spanning Tree Protocol in Chinese, the Protocol can be applied to establishing Tree topology in network, eliminating loop in network, and realizing path redundancy by certain method, but not necessarily realizing path redundancy; the ACK signal is a reception feedback signal, and the feedback is different according to the actual situation, and the purpose used herein is to feed back a signal that the transmission information is actually received to the transmission side from the reception side.
Of course, other disclosed two-layer communication protocols may be used, and implementing communication between two switches by the disclosed two-layer communication protocols requires that the two switches be under the same Vlan and that the communication port cannot be in a blocking state. Therefore, an appropriate manner can be flexibly selected according to actual conditions, and is not particularly limited herein.
With reference to fig. 3, fig. 3 is a flowchart of a method for processing an offline switch due to a configuration exception in a method for rapidly deploying a switch according to an embodiment of the present application.
S301: when the first switch is off-line in the network due to configuration abnormity and the second switch is on-line, modifying the configuration information of the first switch in the whole network topological graph stored on the AC to obtain modified configuration information;
it should be noted that the first switch and the second switch are two switches in the same layer, which are both connected to the same root switch, and the second switch remains connected to the first switch.
S302: and sending the modified configuration information to the root switch, sending the modified configuration information to the second switch by the root switch, and finally forwarding the modified configuration information to the first switch in the off-line state by the second switch so that the first switch is on-line again after the modified configuration information is configured.
Referring to fig. 4, fig. 4 is a schematic diagram of a switch connection manner provided in the embodiment of the present application, where the first switch and the second switch are both connected to a root switch, that is, the first switch and the second switch are both used as lower layers of the root switch and exist in the same layer, and meanwhile, a connection relationship exists between the second switch and the first switch.
Based on the above technical solution, the method for rapidly deploying switches provided in the embodiments of the present application issues a whole network topology map including position structure information of all switches and corresponding configuration information to one switch, and after deployment is completed by using information included in the whole network topology map, the whole network topology map is issued to all connected other switches as a root switch, and when one other switch completes deployment, the whole network topology map is continuously issued as a new root switch repeatedly until all switches in a network are completely deployed. Because the topology map of the whole network carries the switch information corresponding to all layers and positions, the switch information can be obtained only from the recently connected switches, and as the number of layers increases, the number of switches which become a new root switch to execute the issuing operation increases, and the deployment of the whole network switches can be completed quickly in a virus mode.
Because the situation is complicated and cannot be illustrated by a list, a person skilled in the art can realize that many examples exist according to the basic method principle provided by the application and the practical situation, and the protection scope of the application should be protected without enough inventive work.

and the configuration information initialization unit is used for initializing the configuration information of all the same-layer switches and lower-layer switches which are connected with the root switch.
With reference to fig. 6, with reference to the foregoing embodiment, fig. 6 is a timing diagram of an actual operation step of the system for rapidly deploying a switch provided in the embodiment of the present application, and fig. 6 shows an operation step of specifically implementing the rapid deployment switch described in the present application, where the private communication protocol of SSPDU is used:
1. the first root switch is activated and deployed in the AC, and then an SSPDU notification message is broadcasted to the connected sub-switch A at regular time;
2. when the sub-switch A receives the SSPDU notification message, opening the STP of the sub-switch A;
3. after the STP of the sub-switch A is opened, an ACK signal is returned to the root switch to inform the root switch that the sub-switch A can receive the data and send the data;
4. after receiving the ACK signal sent by the sub-switch A, the root switch unicasts an SSPDU configuration message to the sub-switch A;
5. the sub-switch A configures the received configuration information on the sub-switch A to complete the deployment of the sub-switch A;

Furthermore, on the principle of only sending necessary information, when the whole network topological graph is issued to other exchangers, only the target exchanger and the same-layer exchanger and the lower-layer exchanger which have connection relation with the target exchanger are selected, and the upper-layer exchanger part accessed by the target exchanger is removed, because the information is issued only by the same-layer transmission and the upper layer to the lower layer, the clock is not required to contain all the whole network topological graphs; however, in consideration of other principles, such as a unified principle and a redundancy principle, the entire network topology may also be issued all the time, which is not specifically limited herein, and may be implemented by selecting a suitable manner according to different actual situations.
Based on the above content, the method and the system realize virus-type configuration diffusion to the connected and adjacent switches by means of a mode of storing the whole network topological graph and the whole network switch key configuration in the switch and by means of the appointed root switch after completing online according to the whole network topological graph and the whole network switch key configuration, so as to realize rapid deployment of the whole network switch, and the switch is free of activation and manual configuration after replacement, so that plug and play are realized, and when a certain switch is offline due to configuration abnormality, the diffusion of configuration information can be realized by means of the switch as long as one switch connected with the switch is online, so that the offline switch is online again.
