Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of a method for detecting a master/standby switch according to an embodiment of the present invention, where this embodiment is applicable to a situation where a plurality of network cards in a terminal are respectively connected to a plurality of switches and a master line and a standby line are determined in communication lines respectively connected to the plurality of switches, and the method may be executed by a master/standby switch detection apparatus, where the apparatus may be implemented in a software and/or hardware manner, and may generally be integrated in various terminal devices, such as a mobile phone, a tablet computer, or a notebook, as shown in fig. 1a, where the method specifically includes:
In a specific example, the terminal includes a network card a and a network card B, the network card a is physically connected to the switching port P in the switch 1, and the network card B is physically connected to the switching port Q in the switch 2.
The terminal can monitor the port flow of the switching port of each switch connected with the network card. When a network card arranged in a terminal communicates with a connected switch, flow is generated; and in a non-communication state, no traffic is generated.
In an implementation manner of the embodiment of the present invention, optionally, when determining that the local computer does not support the PING protocol, the terminal monitors port traffic of a switching port, which is physically connected to the terminal, in each switch, respectively.
The method for detecting the main and standby switches provided by the embodiment of the invention can be suitable for any terminal, can be used when the terminal supports or does not support the PING protocol, and solves the problem that the main and standby switches cannot be determined when the terminal does not support the PING protocol in the prior art.
And step 120, the terminal acquires a target switch with port flow exceeding a preset flow threshold value, determines the target switch as a main switch, and determines other switches as standby switches.
The terminal may determine the port traffic of the monitoring switch port and a preset traffic threshold, determine the corresponding switch as the primary switch if the port traffic exceeds the preset traffic threshold, and determine the corresponding switch as the standby switch if the port traffic does not exceed the preset traffic threshold. The preset flow threshold may be a very small flow threshold, such as 1 byte per second or 2 bytes per second, etc., which is not limited in this embodiment,
in a specific example, when a switching port connected to a terminal in a switch has a traffic passing through, a port traffic of the switching port may exceed a preset traffic threshold, and a traffic alarm signal corresponding to the switching port may be generated to notify the terminal, so as to instruct the terminal to determine a primary switch according to the traffic alarm signal.
In an implementation manner of the embodiment of the present invention, optionally, if the terminal detects the traffic alarm signal, the terminal identifies a target switch port that sends the traffic alarm signal; and determining the switch corresponding to the target switching port as a target switch with the port flow exceeding a preset flow threshold value.
The traffic threshold may be set in advance in the switch ports where the switches are connected to the terminal, so that the switch ports whose traffic exceeds the traffic threshold send traffic alarm signals to the terminal.
The method comprises the steps that a minimum flow threshold value is set in a switching port where each switch is connected with a terminal, when flow passes through, the flow exceeds a preset flow threshold value, and a flow alarm signal is generated. The terminal can detect the flow alarm signal, identify the switching port generating the flow alarm signal, determine the corresponding switch as a target switch with the port flow exceeding a preset flow threshold value, and determine the target switch as a main switch, and the line between the main switch and the corresponding network card in the terminal can be determined as a main line.
And step 130, setting the communication line between the terminal and the main switch as the main line and setting the communication line between the terminal and the standby switch as the standby line by the terminal.
The terminal can determine a line between the main switch and the corresponding network card as a main line, so that the terminal realizes communication through the network card connected with the main switch, the main line and the main switch. The terminal can determine the line between the standby switch and the corresponding network card as a standby line, so that the terminal starts the standby line when the main line is abnormal.
According to the technical scheme of the embodiment, the terminal monitors the port flow of the switching port which is physically connected with the terminal in each switch respectively; the terminal acquires a target switch with port flow exceeding a preset flow threshold value, determines the target switch as a main switch, and determines other switches as standby switches; the terminal sets the communication line between the terminal and the main switch as a main line and sets the communication line between the terminal and the standby switch as a standby line, and provides a new mode for the terminal to determine the main switch and the standby switch, so that the effect of determining the main line and the standby line among the terminal and a plurality of switch lines can be realized when the terminal does not support the PING protocol.
On the basis of the above embodiment, optionally, if the terminal detects that the switching port physically connected to the terminal in the active switch is closed, it determines that any standby switch is a new active switch; and the terminal switches the communication line between the terminal and the new main switch into the main line.
When the switching port of the main switch physically connected with the terminal is closed, the main line is disconnected, the terminal needs to find a new communication line for communication, the terminal can determine other standby switches as a new main switch, and determine the communication line between the new main switch and the corresponding network card on the terminal as the main line, so that the terminal continues to communicate through the network card connected with the new main switch, the new main line and the new main switch.
If two switches are connected with the terminal, the terminal can directly determine the standby switch as a new main switch; if the number of switches connected to the terminal is more than two, the terminal may determine any one of the at least two standby switches as the new active switch.
Fig. 1b is a schematic diagram of an interaction process of a primary/secondary switch detection method according to an embodiment of the present invention. For example, the switch port of switch a and the switch port of switch B are both connected to terminal C, the switch port of switch a and the switch port of switch B set a traffic threshold to 1, when the switch port in switch a physically connected to the terminal generates a traffic threshold exceeding alarm, the terminal sets the communication line with switch a as a main line, the switch port in switch B physically connected to the terminal does not generate a traffic threshold exceeding alarm, and the terminal sets the communication line with switch B as a spare line. When the switching port physically connected with the terminal in the switch A is closed, the communication line between the switch A and the terminal is switched to a disconnected state, and then the terminal sets the communication line between the switch A and the terminal B as an information main line so as to enable the terminal to keep communication.
Example two
Fig. 2a is a flowchart of a method for detecting a master/standby switch according to a second embodiment of the present invention, which is a further refinement of the foregoing technical solution, and the technical solution in this embodiment may be combined with each optional solution in one or more embodiments.
As shown in fig. 2a, the method specifically includes:
When the terminal supports the PING protocol, the primary and secondary switches may be determined by port flow detection, or may be determined by the method in the second embodiment of the present invention. That is, when the terminal supports the PING protocol, the probe packet of the PING protocol may be sent to each switch.
In an embodiment of the present invention, optionally, the terminal receives an SNMP (Simple Network Management Protocol) message, which is fed back by each switch port for the detection message, where the SNMP message includes a Media Access Control Address (MAC) Address in the terminal learned by the switch; the terminal extracts the MAC address included in the SNMP message from each received SNMP message; the terminal acquires a target switch for sending the effective MAC address, determines the target switch as a main switch, and determines the standby switches by other switches; the terminal sets the communication line between the terminal and the main switch as a main line and sets the communication line between the terminal and the standby switch as a standby line.
The terminal can determine the active switch and the standby switch according to the response of each switch to the detection message of the PING protocol. The switch can learn the MAC address of the network card physically connected in the terminal according to the detection message of the PING protocol, and feed back the MAC address to the terminal in the SNMP message according to the learned MAC address, and correspondingly, the SNMP message comprises the MAC address of the network card physically connected with the switch, which is learned by the switch through the SNMP protocol; the terminal can extract the MAC address of the network card in the SNMP message according to the SNMP message fed back by each switch. Furthermore, the terminal may determine that the MAC address is an effective address when determining that the MAC address is the actual MAC address of the network card.
Optionally, if the identified MAC address does not conform to the structural form of the actual network card address, the MAC address is determined to be an invalid address, for example, when the MAC address is 00-00-00-00-00-00, the MAC address is considered to be an invalid MAC address.
Correspondingly, the switch that sends the SNMP message corresponding to the valid MAC address may be determined as a target switch, the target switch may be determined as a master switch, a communication line between the master switch and the corresponding network card in the terminal may be determined as a master line, and communication lines between other switches and the corresponding network cards in the terminal may be determined as backup lines.
In an implementation manner of the embodiment of the present invention, optionally, the terminal sends a detection message of the PING protocol to a switching port, which is physically connected to the terminal, in each switch at preset time intervals; wherein the time interval is greater than or equal to an empirical value of the network congestion duration.
The terminal can send the detection message of the PING protocol to each switch at a certain time interval, so that the situation that the detection message of the PING protocol is frequently sent to a main switch when a network card is paused and the main switch cannot feed back the actual MAC address of the network card can be avoided; the terminal will re-determine the new main switch and send the detection message of the PING protocol, and still cannot acquire the actual MAC address, causing frequent changes of the main line between the terminal and each switch.
Specifically, the empirical value of the network congestion duration may be obtained by measuring the network congestion duration for multiple times, and averaging or processing the time values obtained multiple times by taking the maximum value.
The terminal can determine a line between the main switch and the corresponding network card as a main line, so that the terminal realizes communication through the network card connected with the main switch, the main line and the main switch. The terminal can determine the line between the standby switch and the corresponding network card as a standby line, so that the terminal starts the standby line when the main line is abnormal. If the switching port physically connected with the terminal in the main switch is closed, the communication line between the terminal and the main switch is switched to a disconnected state, and further the terminal needs to find a new line for communication again, other standby switches may be determined as new main switches, and the line communication line between the new main switch and the terminal is determined as an information main line, so that the terminal maintains communication through the network card connected with the new main switch, the main line and the new main switch.
According to the technical scheme of the embodiment, when the terminal determines that the local machine supports the PING protocol, the terminal sends a detection message of the PING protocol to a switching port which is physically connected with the terminal in each switch; the terminal determines a main switch and a standby switch in each switch according to the response of each switch port to the detection message; the terminal sets the communication line between the terminal and the main switch as the main line and sets the communication line between the terminal and the standby switch as the standby line, and provides a new mode for the terminal to determine the main switch and the standby switch, so that the main line and the standby line in the terminal and a plurality of switch lines can be determined in other modes when the terminal supports the PING protocol, and meanwhile, the effect that the terminal frequently switches the communication lines during the pause of a communication network card cannot be caused.
Fig. 2b is a schematic diagram of an interaction process of a primary/secondary switch detection method according to a second embodiment of the present invention. Illustratively, the switch port of the switch a and the switch port of the switch B are both connected to the terminal C, the switch a feeds back an SNMP message through a detection message for the PING protocol, the SNMP message includes an MAC address of a network card physically connected to the switch port of the switch a in the terminal C learned by the switch, and the terminal C receives the SNMP message and extracts the MAC address in the SNMP message.
And when the MAC address acquired by the terminal C is the actual MAC address of the network card in the terminal C, judging that the line of the switch A and the line of the terminal C are the main line, feeding back an SNMP message by the switch B aiming at a detection message of a PING protocol, wherein the SNMP message comprises the MAC address of the network card which is learned by the switch and is physically connected with the switching port of the switch B in the terminal C, and receiving the SNMP message by the terminal C to extract the MAC address in the SNMP message. And if the MAC address acquired by the terminal C is 00-00-00-00-00-00, judging that the line of the switch B and the terminal C is a standby line. When the terminal C detects that the switching port of the switch a physically connected with the terminal C is closed, the terminal C switches the communication line with the switch a to a line disconnection state, and further, the terminal C sets the communication line with the switch B as an information main line, so that the terminal C keeps communication.
Fig. 3 is a flowchart of a method for detecting a primary/standby switch according to an embodiment of the present invention, and as shown in fig. 3, a use process according to an embodiment of the present invention may be: judging whether the terminal supports a PING protocol or not; if the terminal does not support the PING protocol, monitoring the port flow through each switch, and judging whether the port flow exceeds a preset flow threshold value; if the flow rate exceeds the preset flow rate threshold value, the switch sends a flow rate alarm signal to the terminal, the terminal identifies the switch which sends the flow rate alarm signal and determines the switch as a main switch, and a line between the main switch and the terminal is a main line; if the flow rate does not exceed the preset flow rate threshold value, the switch does not send a flow rate alarm signal to the terminal, the terminal determines the switch which does not send the flow rate alarm signal as a standby switch, and a line between the standby switch and the terminal is a standby line.
If the terminal supports the PING protocol, the terminal can send a detection message of the PING protocol to each switch, and the switches learn the MAC address of the terminal based on the detection message and feed back the learned MAC address to the terminal through the SNMP message; the terminal judges whether the obtained MAC address is zero or not; if the obtained MAC address is zero, determining that the exchanger which learns that the MAC address of the terminal is zero is a standby exchanger, and setting a communication line between the standby exchanger and the terminal as a standby line; and if the obtained MAC address is the actual MAC address, determining that the switch which learns that the MAC address of the terminal is the actual MAC address is the main switch, and setting a communication line between the main switch and the terminal as a main line.
