Description
Technical Field
The present application relates to the field of computer communications technologies, and in particular, to a link state maintenance method and apparatus.
Background
An optical-electrical composite port (combo) is a communication port for being installed on electronic devices such as computers, switches, routers, etc., and generally consists of a pair of an optical port and an electrical port that share the same forwarding port. The combo port has two modes of operation: an optical port mode and an electrical port mode; when the optical port mode is set, the optical port is used for data communication; when the mobile terminal is in the electric port mode, the electric port is used for communication; and the combo port can only be in one of the optical port mode and the electrical port mode at the same time.
When the combo port is used, a user is required to manually set a specific working mode of the combo port, namely, the user manually inputs a configuration instruction to the equipment; the device is internally provided with a driver corresponding to the combo port, and the driver configures the working mode of the combo port according to the configuration instruction input by the user, so that the combo port can work in one working mode.
However, since the mode of manually inputting the configuration command is adopted in the method for setting the combo port working mode, once the working mode of the combo port needs to be changed, namely the communication link of the device needs to be changed, a manual method is also needed, and the communication link of the device is very inconvenient to maintain.

In a first aspect, a method for maintaining a link state is provided, including:

if the optical port is detected to receive an optical signal, acquiring a current corresponding link state of the photoelectric composite port;
and when the current corresponding link state of the photoelectric composite port is in a disconnection state, switching the working mode of the photoelectric composite port.

In the process, whether the photoelectric composite port is switched or not is judged according to whether the optical port receives an optical signal or not and the link state of the port currently used by the photoelectric composite port, once the link state is disconnected, the working mode of the photoelectric composite port is switched, and the other port is tried to be used for communication, so that the automatic maintenance of the communication link is realized. Moreover, due to the fact that manual port switching operation on the equipment is not needed, the equipment can be specifically installed according to actual needs, and the problem that inconvenience is caused due to manual port setting on the equipment in the later period is not needed to be considered.

Detailed Description
Referring to fig. 1, an embodiment of the present application provides a device hardware architecture of a combo port. The electrical port and the optical port are connected to a same Physical Layer (PHY) chip and connected to a same Media Access Control (MAC) chip, and the electrical port is connected to the PHY chip through a converter (transducer). Of the combo ports, only one of the electrical port and the optical port can be in use at the same time. In order to maintain the communication link state, when the combo port changes from a connected (link up) state to a disconnected (link down) state, another port needs to be enabled for communication when the other port can be used.
When the link state is maintained, whether the optical port of the photoelectric composite port receives an optical signal is detected once at preset time intervals, and if the optical port receives the optical signal, the link state corresponding to the photoelectric composite port at present is obtained; and switching the working mode of the photoelectric composite port once the current corresponding link state of the photoelectric composite port is disconnected. Therefore, when the link state of the photoelectric composite port is a connection state, the working mode of the photoelectric composite port cannot be switched no matter the current link adopts the optical port or the electric port; once the current link has a problem, the working mode of the photoelectric composite port is switched, and the smoothness of the link is automatically maintained, so that the problem that the working mode of the combo port needs to be manually changed in the prior art, and the communication link is inconvenient to maintain can be solved.
The link state maintenance according to the present application refers to a link maintenance process after receiving an optical signal, and if no optical signal is received, it means that it is not necessary to switch from the electrical port mode to the optical port mode. Because the optical signal detection is easy to realize and simple and convenient to implement, unnecessary mode switching is avoided by judging whether the optical signal is received in advance, equipment resources can be saved, and the link maintenance efficiency is improved.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The combo port related to the application has two working modes: an optical port mode of operation and an electrical port mode of operation. In the optical port working mode, the device uses the optical port to communicate; in the electrical port mode of operation, the device communicates using the electrical port.
When the device communicates by using the combo port, the optical port and the electric port are not always connected with corresponding optical fibers or cables; when the optical port is not connected with the optical fiber and the electric port is not connected with the cable, the combo port is in a linkdown state, and if the optical port is inserted into the optical fiber firstly and can communicate, the combo port communicates by using the optical port; the combo port communicates using the electrical port if the electrical port is plugged into the cable first and communication is enabled. If the combo port communicates using either of the optical port and the electrical port, it will not be used even if the other port is able to communicate. When the optical port and the electric port can normally communicate, once the combo port changes the state from the link up state to the link down state due to line disconnection and the like, the combo port is switched to the other port for communication. When the equipment is powered on, if the optical port and the electric port can normally communicate, the combo port preferentially uses the optical port to communicate.
In the embodiment of the present application, as shown in fig. 2, a flowchart of a link state maintenance method provided in an embodiment of the present application is provided, and in the embodiment of the present application, a main body responsible for executing the method may be a device that installs a combo port and communicates with the outside through the combo port. The method comprises the following steps:
s201: and detecting whether the optical port of the photoelectric composite port receives the optical signal or not according to a preset time interval.
In a specific implementation, the optical port generally uses a Small Form Pluggable (SFP) optical module and an optical fiber for communication. The optical module is used for realizing conversion between optical signals and electric signals and conforms to a common Multi-Source Agreement (MSA). After the optical port is inserted into the optical module, the equipment can set the speed and the duplex of the optical port according to MSA protocol information; and after the optical fiber is accessed to the optical port, the optical port performs negotiation communication with the opposite-end optical port through the optical fiber based on the set speed and duplex, and if the negotiation is passed, the optical port links up. In this process, to enable the optical port to link up, it is necessary that the optical port is inserted into the optical module and an optical signal is received at the optical port.
Specifically, when optical port communication is performed, two General Purpose Input/Output (GPIO) are generally used, that is, GPIO _ PIN _ SFPX _ MD and GPIO _ PIN _ SFPX _ LOS. The GPIO _ PIN _ SFPX _ MD is an in-place GPIO of the optical module and is used for identifying whether the optical module is inserted into the optical port or not; GPIO _ PIN _ SFPX _ LOS is an optical signal GPIO used to identify whether an optical signal is received by an optical port. By reading GPIO _ PIN _ SFPX _ MD and GPIO _ PIN _ SFPX _ LOS, it can be specifically known whether the optical port receives the optical signal, as specifically shown in fig. 5.
S202: and if the optical port is detected to receive the optical signal, acquiring the current corresponding link state of the photoelectric composite port.
In a specific implementation, when the current corresponding link state of the combo port is connected, the working mode of the current combo port is not switched, and only when the current corresponding link state is disconnected, the working mode of the combo port is switched from the current state to another working mode. Therefore, the link state currently corresponding to the combo port is to be acquired, and whether the link state currently corresponding to the optical combo port is connected or not is checked.
Specifically, when a combo port communicates using an optical port and an electrical port, a parameter for identifying whether the link state of the port is normal can be obtained from the specific port: PortLinkStatus. The PortLinkStatus is transmitted to the MAC chip; by reading the PortLinkStatus parameter in the MCA chip, the current corresponding link state of the combo port can be obtained. When PortLinkStatus is linkup, the current corresponding link state of the combo port is a connection state; and when the PortLinkStatus is linkDown, the current corresponding link state of the combo port is in a disconnection state.
The device can read the PortLinkStatus parameter of the combo port, and judge the current corresponding link state of the combo port according to the specific content of the PortLinkStatus, as shown in fig. 5.
S203: and when the current corresponding link state of the photoelectric composite port is disconnected, switching the working mode of the photoelectric composite port.
In a specific implementation, if the current link state corresponding to the combo port is disconnected, there may be the following two cases:
i: the current working mode of the port is an electric port mode, but the link of the electric port has problems. Since it has been detected that the optical port receives the optical signal, the optical fiber is connected to the default optical port, and therefore, the operation mode of the combo port is switched from the electrical port mode to the optical port mode, and communication using the optical port is attempted.
II: the working mode of the current port is an optical port mode, but the link of the optical port has problems. At this time, even if it is detected that the optical port receives the optical signal, whether the communication link of the optical port is capable of performing normal communication depends not only on whether the optical fiber is inserted into the optical port, but also on other factors (which are described above and are not described here again), so that the operation mode of the combo port is switched from the optical port mode to the electrical port mode, and communication using the electrical port is attempted.
In the link state maintenance method provided in the embodiment of the present application, whether an optical port in the optical electrical composite port receives an optical signal is detected according to a preset time interval, and if it is detected that the optical port receives the optical signal and it is detected that a link state currently corresponding to the optical electrical composite port is disconnected, a working mode of the optical electrical composite port is automatically switched, that is, switching is performed between an optical port mode and an electrical port mode. In the process, whether the photoelectric composite port is switched or not is judged according to whether the optical port receives an optical signal or not and the link state of the port currently used by the photoelectric composite port, once the link state is disconnected, the working mode of the photoelectric composite port is switched, and the other port is tried to be used for communication, so that the automatic maintenance of the communication link is realized. Moreover, due to the fact that manual port switching operation on the equipment is not needed, the equipment can be specifically installed according to actual needs, and the problem that inconvenience is caused due to manual port setting on the equipment in the later period is not needed to be considered. On the other hand, in the application, since whether the optical signal is received or not is detected at preset time intervals, the problem of the equipment communication link can be timely found, and the hysteresis of manual operation is avoided.
It should be noted that, in the link state maintenance method provided in this embodiment of the application, if the optical port can receive the optical signal all the time and the link state corresponding to the optical-electrical composite port is disconnected all the time, the working mode of the optical-electrical composite port is continuously switched between the optical port mode and the electrical port mode until the link state of the optical-electrical composite port in a certain working mode is connected.
In order to avoid that the system resources are always occupied due to the above possible situations, in the link state maintenance method provided in the embodiment of the present application, a counter may be set, where the counter is configured to count the number of times of switching the working mode of the optical electrical composite port, and the count of the counter is incremented by 1 every time the working mode of the optical electrical composite port is switched; once the link state linkup of the photoelectric composite port is detected, resetting the counter to zero; after the counter counts to the preset times, no matter which working mode the photoelectric composite port is in at the moment, the working mode of the photoelectric composite port can be temporarily stopped to be switched, the current working mode is kept, and the link state maintenance method provided by the application is restarted until the preset time.
Referring to fig. 3, in the link state maintenance method provided in the embodiment of the present application, on the basis of the above embodiment, the method further includes:
s301: and if the optical port is detected not to receive the optical signal, acquiring the current working mode of the photoelectric composite port.
S302: and if the obtained working mode of the photoelectric composite port is an optical port mode, switching the working mode of the photoelectric composite port into an electric port mode.
S303: and if the obtained working mode of the photoelectric composite port is an electric port mode, keeping the current working mode of the photoelectric composite port.
In a specific implementation, when it is detected that the optical port does not receive the optical signal, it is considered that the optical fiber on the optical port is unplugged, or the optical module is not plugged into the optical port all the time. Therefore, if the working mode of the current optical-electrical composite port is the optical port mode, since the optical port cannot communicate any more, the working mode of the optical-electrical composite port is switched to the electrical port mode, and an attempt is made to establish a communication link in the electrical port mode. If the current working mode of the optical-electrical composite port is the electrical port mode, and the optical port is not inserted with the optical fiber, even if the working mode of the optical-electrical composite port is switched to the optical port mode, the optical port cannot be used for communication, so that in order to avoid resource waste, the optical-electrical composite port is kept in the current working mode, namely, the electrical port mode.
The embodiment of the present application further provides another link state maintenance method, and on the basis of the several embodiments, after obtaining the current corresponding link state of the optical electrical composite port, the method further includes:
and when the current corresponding link state of the photoelectric composite port is a connection state, maintaining the current working mode of the photoelectric composite port.
In a specific implementation, because at the same time, the optical-electrical composite port can only be in one working mode, and in this working mode, only the corresponding port can be used for communication, when the current corresponding link state of the optical-electrical composite port is a connection state, there may be two cases:
i: the photoelectric composite port is in an optical port mode, and the photoelectric composite port communicates by using an optical link corresponding to the optical port; II: the electro-optical-electro-composite port is in an electrical port mode, and the electro-optical-electro-composite port communicates using an electrical link corresponding to the electrical port. At this time, whether the optical port receives the optical signal or not, the optical-electrical composite port maintains the current working mode until the corresponding link state of the optical-electrical composite port in the current working mode is disconnected and the optical port is detected to receive the optical signal, so that the working mode of the optical-electrical composite port is switched.
In addition, in order to ensure that the optical port is preferentially used for communication when both the optical port and the electrical port can communicate, when the device is powered on and started, the working mode of the optical-electrical composite port is set to be the optical port mode.
In this mode, the optoelectrical composite port will first attempt to communicate using the optical port; if the opto-electronic composite port fails to link up in the optical port mode, the opto-electronic composite port is switched from the optical port mode to the electrical port mode.
Referring to fig. 4, in order to ensure that the device can quickly establish a communication link when being powered on, after the working mode of the optical electrical composite port is set to the optical port mode, before detecting whether the optical port of the optical electrical composite port receives an optical signal according to a preset time interval, the method further includes:
s401: and acquiring the link state of the photoelectric composite port in the optical port mode.
S402: and if the link state of the photoelectric composite port in the optical port mode is a disconnection state, switching the working mode of the photoelectric composite port into an electric port mode.
In specific implementation, when the device is powered on and started, after the working mode of the optical-electrical composite port is set to the optical port mode, the link state of the optical-electrical composite port in the optical port mode is obtained. If the link state of the photoelectric composite port is in a disconnection state, the working mode of the photoelectric composite port is switched to an electric port mode instead of passively waiting for a preset time interval, so that the starting speed of the photoelectric composite port is increased when the device is powered on and started.
It should be noted that the preset time interval is greater than the time of the corresponding port linking up after the photoelectric composite port is set to the operating mode.
Referring to fig. 6, an embodiment of the present application further provides a specific example of a link state maintenance method, including:
s601: when the equipment is powered on and started, the working mode of the combo port is initialized and set to be the optical port mode.
The following link maintenance steps are executed at preset time intervals:
s602: detecting whether the optical port receives an optical signal, if not, skipping to S603; if so, then jump to S606.
S603: detecting whether the working mode of the combo port is an optical port mode, and if so, jumping to S604; if not, then jump to S605.
