Description

Technical Field

[0001] This application belongs to the field of switching equipment technology, and particularly relates to a communication method, apparatus, switching equipment and storage medium. Background Technology

[0002] With the development of network communication and big data application technologies, network virtualization technology (e.g., stacking virtualization technology between multiple box-type or chassis-type devices) is commonly used in large-scale campus networks and data center networks to improve service capacity, data throughput, and network management efficiency. Generally, to ensure high-bandwidth data transmission between devices within a stacked virtualization system, high-speed optical ports are typically selected as data forwarding ports between the stacked devices, and optical modules are installed on the optical ports of the switching equipment. The relevant rate configuration method usually involves adaptively configuring both the switching equipment and the optical module side based on the supported rates of the optical modules inserted into the optical ports of the switching equipment, so that both the switching equipment and the optical modules can operate at their highest matching rates.

[0003] However, stacked virtualization technology itself consumes some bandwidth. For example, data packet forwarding between devices in stacked virtualization technology needs to be achieved through stacking headers, which consumes some bandwidth (for example, in small packet forwarding scenarios, the forwarding rate of user data packets may be less than 80% of the total physical bandwidth of the port); and the internal protocol messages in stacked virtualization technology also consume some forwarding bandwidth, reducing the actual effective forwarding bandwidth of user data packets and affecting the transmission efficiency of user data packets.

[0004] Therefore, how to improve the forwarding bandwidth of user data packets has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, embodiments of this application provide a communication method, apparatus, switching device, and storage medium that can determine at least one effective overclocking rate and construct an overclocking rate set from at least one overclocking rate supported by the switching device and supported by the target optical module based on the channel state of the optical module, and select the target overclocking rate from it for communication. This realizes adaptive selection of effective rate based on the state of the switching device and the optical module, improves the forwarding bandwidth of user data packets, and thus improves data transmission efficiency.

[0022] With the development of network communication and big data application technologies, network virtualization technology (e.g., stacking virtualization technology between multiple box-type or chassis-type devices) is commonly used in large-scale campus networks and data center networks to improve service capacity, data throughput, and network management efficiency. Generally, to ensure high-bandwidth data transmission between devices within a stacked virtualization system, high-speed optical ports are typically selected as data forwarding ports between the stacked devices, and optical modules are installed on the optical ports of the switching equipment. The relevant rate configuration method usually involves adaptively configuring both the switching equipment and the optical module side based on the supported rates of the optical modules inserted into the optical ports of the switching equipment, so that both the switching equipment and the optical modules can operate at their highest matching rates.

[0023] However, stacked virtualization technology itself consumes some bandwidth. For example, data packet forwarding between devices in stacked virtualization technology needs to be achieved through stacking headers, which consumes some bandwidth (for example, in small packet forwarding scenarios, the forwarding rate of user data packets may be less than 80% of the total physical bandwidth of the port); and the internal protocol messages in stacked virtualization technology also consume some forwarding bandwidth, reducing the actual effective forwarding bandwidth of user data packets and affecting the transmission efficiency of user data packets.

[0024] To address the aforementioned problems, embodiments of this application provide a communication method, apparatus, switching device, and storage medium. When physical link connectivity is detected, the target frequency range of the target optical module is obtained, at least one overclocking rate within the target frequency range is acquired, and the receiving channel state and transmitting channel state of the target optical module corresponding to each overclocking rate are determined. Based on the receiving and transmitting channel states of the target optical module corresponding to each overclocking rate, an overclocking rate set including at least one effective overclocking rate is constructed. A target overclocking rate is selected from the overclocking rate set, and communication with the target terminal is performed based on the target overclocking rate. This achieves adaptive selection of effective rates based on the states of the switching device and optical modules, improving the forwarding bandwidth of user data packets and thus enhancing data transmission efficiency.

[0025] It should be noted that the communication method, apparatus, switching equipment and storage medium provided in this application can be used in the field of switching equipment, and this application does not limit the application field of the communication method, apparatus, switching equipment and storage medium.

[0026] The aforementioned switching equipment is used to indicate devices that support communication functions (including but not limited to switches (e.g., optical switches, program-controlled switches, etc.), routers, wireless controllers AC+AP, etc.). This application embodiment does not impose any special restrictions on the specific type of the switching equipment.

[0027] Figure 1 This is one of the flowcharts illustrating the communication method provided in an embodiment of this application. For example... Figure 1 As shown in the embodiments of this application, the communication method includes the following steps: S101. When physical link connectivity is detected, the target frequency range of the target optical module is obtained; wherein, the target optical module refers to the optical module mounted on the target optical port, and the target optical port is the optical port corresponding to the physical link.

[0028] In applications, switching equipment includes multiple optical ports, on which optical modules can be mounted / inserted. Physical links are established with peer devices via these optical modules to enable communication. When a physical link is detected, the optical port corresponding to that physical link is identified as the target optical port, and the optical module mounted / inserted on the target optical port is designated as the target optical module. The target frequency range of the target optical module is then obtained.

[0029] It is understandable that the target optical module can support multiple frequencies, and the target frequency range is determined based on all the frequencies supported by the target optical module.

[0030] In some embodiments, a polling detection mechanism can be used to poll the presence (absent) signals of each optical port in the switching equipment. When no presence (absent) signal is detected, it is determined that an optical module has been inserted into the optical port. The optical module is then identified to determine its type, thereby obtaining the target frequency range of the optical module. Based on the rate type of the optical port and the type of the currently inserted optical module, the rate of both the optical port and the optical module is set to the maximum rate supported by both parties, so as to communicate with the target terminal at the other end of the physical link at the aforementioned maximum rate.

[0031] As an example and not a limitation, when the physical link connection of the target optical port on the switching device is detected, communication is established with the microcontroller unit (MCU) of the corresponding target optical module. That is, by reading the protocol specified by the standard protocol or the content of the user-defined protocol, the frequency range supported by the transmit channel (CDR) and receive channel (CDR) of the target optical module and the frequency range supported by each range are obtained, as well as information such as the current default frequency range of the transmit channel (CDR) and receive channel (CDR) of the target optical module are obtained.

[0032] The execution entity in this application embodiment can be a switching device or a communication device installed in the switching device. The communication device can be implemented by software or by a combination of software and hardware.

[0033] S102. Obtain at least one overclocking rate within the target frequency range and determine the channel state of the target optical module corresponding to each overclocking rate; wherein, the channel state includes the receiving channel state and the transmitting channel state.

[0034] In the application, at least one overclocking rate within the target frequency range supported by the target optical module is obtained, and the channel state of the target optical module corresponding to each overclocking rate is determined. The channel state includes, but is not limited to, the receive channel state and the transmit channel state. Both the receive channel state and the transmit channel state include locked and unlocked states.

[0035] As an example, and not a limitation, a preset frequency range file for the switching device can be pre-built, which includes at least one overclocking rate supported by the switching device. In this way, based on the preset frequency range file, at least one overclocking frequency supported by the switching device and located within the target frequency range supported by the target optical module can be obtained.

[0036] For example, when the switching device is a switch, the ASIC chip of the switch can be read to obtain the overclocking rates supported by all links of the switch, a preset frequency range file of the switch can be created, and the overclocking rate information can be stored. When the switch starts up, the preset frequency range file is read and the overclocking rate information is stored to facilitate subsequent rate configuration operations.

[0037] As an example, and not a limitation, when the switch starts up, if the preset frequency range file is not detected, it will automatically read all the overclocking rates supported by the ASIC chip, create the preset frequency range file, and write the overclocking rate information.

[0038] As an example, and not a limitation, creating a preset frequency range file and writing overclocking rate information includes two methods. The automatic generation method involves the switch's built-in program automatically reading the overclocking rates supported by the ASIC chip, creating the preset frequency range file, and automatically writing the overclocking rate information. The manual generation method involves, upon receiving a user instruction, determining the different overclocking rates supported by different links on the user-specified ASIC chip, creating the preset frequency range file, and writing only the user-specified overclocking rate information. The user instruction can be a command or request sent by the user through a user terminal; or it can be an instruction or request automatically generated based on the user's actions on the current switch (such as pressing external buttons, clicking or dragging the current switch screen).

[0039] It is understandable that the target optical module's receive and transmit channels (CDRs) can only enter a locked state and normally receive or transmit data when the port rate (also known as overclocking rate or overclocking frequency) configured on the target optical port is within the frequency range supported by the target optical module's receive and transmit channels (CDRs). By selecting at least one overclocking frequency within the target frequency range supported by the target optical module from the preset frequency range file supported by the switching equipment, at least one overclocking frequency supported by both the switching equipment and the target optical module can be obtained, thereby determining the receive and transmit channel states of the target optical module corresponding to each of the aforementioned overclocking frequencies.

[0040] like Figure 2 As shown, in some embodiments, S102 includes the following steps: S1021. Determine at least one first overclocking rate within the target frequency range.

[0041] In the application, at least one overclocking rate within the target frequency range is determined and designated as the first overclocking rate.

[0042] For example, in the preset frequency range file supported by the switching device, at least one overclocking frequency located within the target frequency range is found and determined as the first overclocking rate.

[0043] S1022. Traverse each first overclocking rate, set the target optical port rate to the first overclocking rate in sequence, and determine the corresponding receiving channel status and transmitting channel status.

[0044] In the application, each first overclocking rate is traversed, and the rate of the target optical port is set to the corresponding first overclocking rate in turn, so as to obtain the receiving channel status and transmitting channel status of the target optical module corresponding to each first overclocking rate.

[0045] For example, in the preset frequency range file, the first overclocking rate within the target frequency range includes rate 1, rate 2, rate 3... rate n. Each of the above first overclocking rates can be iterated over, and the rate of the target optical port can be sequentially set to rate 1, rate 2, rate 3... rate n. This allows for the sequential acquisition of the receiving channel status and transmitting channel status of the target optical module corresponding to rate 1; the receiving channel status and transmitting channel status of the target optical module corresponding to rate 2; and the receiving channel status and transmitting channel status of the target optical module corresponding to rate n.

[0046] In some embodiments, the following steps are included after S1022: If at least one of the receiving channel states and the transmitting channel state is in an unlocked state, the corresponding first overclocking rate is determined to be an invalid overclocking rate.

[0047] In application, when at least one of the receiving channel states and the transmitting channel states of the target optical module is in an unlocked state (for example, the receiving channel state is unlocked, the transmitting channel state is unlocked, or both the receiving channel state and the transmitting channel state are unlocked), the corresponding first overclocking rate is determined to be an invalid overclocking rate.

[0048] Optionally, a corresponding invalid flag can be added to the invalid overclocking rate. This allows invalid overclocking rates carrying invalid flags to be identified, preventing invalid overclocking rates from being grouped together in the overclocking rate set.

[0049] For example, if the receiving channel of the target optical module corresponding to rate 1 is unlocked and the transmitting channel is locked, rate 1 is determined to be an invalid overclocking rate, and a corresponding invalid flag is added to rate 1; if the receiving channel of the target optical module corresponding to rate 2 is locked and the transmitting channel is unlocked, rate 2 is determined to be an invalid overclocking rate, and a corresponding invalid flag is added to rate 2; if both the receiving and transmitting channels of the target optical module corresponding to rate 3 are unlocked, rate 3 is determined to be an invalid overclocking rate, and a corresponding invalid flag is added to rate 3.

[0050] It is understandable that when both the receiving channel state and the transmitting channel state of the target optical module are locked, the corresponding first overclocking rate is determined as the effective overclocking rate, and an overclocking rate set is constructed based on each effective overclocking rate.

[0051] For example, if the receiving channel state and transmitting channel state of the target optical module corresponding to rate 4 are both locked, rate 4 is determined as an effective overclocking rate and added to the overclocking rate set.

[0052] like Figure 3As shown, in some embodiments, after S101, the following steps are further included: S201. When the target frequency range includes multiple frequency levels, traverse each frequency level to find the target frequency level. S202. Generate corresponding control commands based on each target frequency level; wherein, the control commands are used to control the target optical module to update the current frequency level to the corresponding target frequency level.

[0053] In application, when the target frequency range supported by the transmit and receive channels of the target optical module includes multiple frequency levels, each frequency level is traversed to obtain the target frequency level, and corresponding control commands are generated based on each target frequency level. The control commands are used to control the target optical module to update the current frequency level to the corresponding target frequency level.

[0054] For example, the target optical module's transmit and receive channels support both low-frequency and high-frequency ranges. The low-frequency and high-frequency ranges are iterated to determine the target frequency range. A first control command is generated based on the first target frequency range (e.g., a low-frequency range) to control the target optical module to update its current frequency range to the first target frequency range. A second control command is generated based on the second target frequency range (e.g., a high-frequency range) to control the target optical module to update its current frequency range to the second target frequency range.

[0055] like Figure 4 As shown, in some embodiments, S102 further includes the following step: S1023. Determine multiple second overclocking rates corresponding to each target frequency level; S1024. For each target frequency level, iterate through each second overclocking rate corresponding to the target frequency level, set the rate of the target optical port to the second overclocking rate in sequence, and determine the receiving channel state and transmitting channel state corresponding to each second overclocking rate.

[0056] In the application, multiple second overclocking rates corresponding to each target frequency range are determined. For each target frequency range, the second overclocking rates corresponding to that target frequency range are iterated through, and the rate of the target optical port is sequentially set to each second overclocking rate corresponding to that target frequency range, so as to obtain the receive channel status and transmit channel status of the target optical module corresponding to each second overclocking rate corresponding to that target frequency range.

[0057] For example, multiple second overclocking rates corresponding to each target frequency level can be determined in a preset frequency range file, thereby obtaining multiple second overclocking rates supported by the switching device and corresponding to each target frequency level of the target optical module.

[0058] For example, when generating a first control command based on a first target frequency range (e.g., a low frequency range) to control the target optical module to update its current frequency range to the first target frequency range, multiple second overclocking rates corresponding to the first target frequency range are determined in a preset frequency range file (e.g., the low frequency range includes rate x, rate y, and rate z). For the first target frequency range, each second overclocking rate corresponding to that range is traversed, and the rate of the target optical port is sequentially set to each second overclocking rate corresponding to the first target frequency range. The receiving channel state and transmitting channel state of the target optical module corresponding to each of the above-mentioned second overclocking rates (including rate x, rate y, and rate z) are obtained, thereby obtaining the channel state of the target optical module corresponding to rate x, rate y, and rate z in the low frequency range. Furthermore, when generating a second control command based on a second target frequency level (e.g., a high frequency level) to control the target optical module to update its current frequency level to the second target frequency level, multiple second overclocking rates (e.g., the high frequency level includes rate a, rate b, and rate c) corresponding to the second target frequency level (e.g., a high frequency level) are determined in a preset frequency range file. For each second target frequency level, the second overclocking rate corresponding to that high frequency level is traversed, and the rate of the target optical port is sequentially set to each second overclocking rate corresponding to the second target frequency level. The receiving channel state and transmitting channel state of the target optical module corresponding to each of the above-mentioned second overclocking rates (including rate a, rate b, and rate c) are obtained, thereby obtaining the channel state of the target optical module corresponding to rate a, rate b, and rate c in the high frequency level.

[0059] By adjusting the target optical module to the target frequency range and determining the receive channel status and transmit channel status of the target optical module when the target optical port is configured with the overclocking rate corresponding to the target frequency range, the effective overclocking rate can be identified, which can improve the compatibility between the effective overclocking rates in the overclocking rate set and the switching equipment and the target optical module.

[0060] S103. Based on the channel state of the target optical module corresponding to each overclocking rate, an overclocking rate set is constructed; wherein, the overclocking rate set includes at least one effective overclocking rate.

[0061] In application, based on the channel state of the target optical module corresponding to each overclocking rate, at least one effective overclocking rate is determined, and an overclocking rate set is constructed based on the above at least one effective overclocking rate.

[0062] like Figure 5 As shown, in some embodiments, S103 includes the following steps: S1031. When both the receiving channel state and the transmitting channel state of the target optical module are locked, determine the corresponding second overclocking rate as the effective overclocking rate. S1032. Determine the effective overclocking rates corresponding to each target frequency level and construct an overclocking rate set.

[0063] In the application, when both the receiving channel state and the transmitting channel state of the target optical module are locked, the corresponding second overclocking rate is determined as the effective overclocking rate, thereby obtaining at least one effective overclocking rate corresponding to each target frequency level, and constructing the corresponding overclocking rate set.

[0064] For example, in the low-frequency range, the channel states of the target optical module corresponding to rate x include: both the receive and transmit channels are locked; the channel states of the target optical module corresponding to rate y include: the receive channel is unlocked and the transmit channel is locked; the channel states of the target optical module corresponding to rate z include: both the receive and transmit channels are locked. The effective overclocking rates for the low-frequency range are determined to be rates x and z. In the high-frequency range, the channel states of the target optical module corresponding to rate a include: both the receive and transmit channels are locked; the channel states of the target optical module corresponding to rate b include: both the receive and transmit channels are locked; the channel states of the target optical module corresponding to rate c include: both the receive and transmit channels are locked. The effective overclocking rates for the high-frequency range are determined to be rates a, b, and c. The resulting overclocking rate set includes rates a, b, c, x, and z.

[0065] In some embodiments, prior to S101, the following steps are included: Obtain at least one overclocking rate that the switching device can support, and construct a preset frequency range file; wherein, the overclocking rate includes a first overclocking rate and a second overclocking rate.

[0066] In the application, at least one overclocking rate that the current switching device can support is obtained, and the corresponding preset frequency range file is constructed.

[0067] The overclocking rate includes a first overclocking rate and a second overclocking rate. The first overclocking rate and the second overclocking rate may be the same or different.

[0068] S104. Select a target overclocking rate from the overclocking rate set, and communicate with the target terminal based on the target overclocking rate; wherein, the target terminal is the terminal device corresponding to the target optical module.

[0069] In application, an overclocking rate is selected from the overclocking rate set and determined as the target overclocking rate. The current rate of the target optical port is then updated to this target overclocking rate to enable communication with the target terminal. Here, the target terminal refers to the terminal device corresponding to the target optical module connected as described above.

[0070] As an example and not a limitation, the methods for selecting a target overclocking rate from the set of overclocking rates include, but are not limited to, random selection and maximum value selection. Random selection means randomly selecting an effective overclocking rate from the set of overclocking rates and determining it as the target overclocking rate. Maximum value selection means selecting the effective overclocking rate with the largest value from the set of overclocking rates and determining it as the target overclocking rate.

[0071] In practical applications, the same type of optical module can be physically linked using fiber optic cables of different lengths in different business scenarios. The same type of optical module or fiber optic cable may exhibit different bit error rates at the same overclocking rate. That is, at the same overclocking rate, the transmit and receive channel states of the optical module may be inconsistent, and the overclocking rate matched to the switching equipment on the optical module will also differ at different temperatures. By selecting the transmission rate with the highest forwarding efficiency from a set of multiple effective overclocking rates supported by the switching equipment within the target frequency range of the target optical module, which simultaneously adapts to both the current switching equipment and the target terminal, the bandwidth consumed during data transmission (e.g., the additional bandwidth consumed by internal communication protocols and management protocols) can be reduced, and the effective forwarding bandwidth of data transmission can be increased, thereby improving data transmission efficiency. This method is applicable to optical modules supporting standard protocols (e.g., optical modules supporting the 8636 protocol); or to user-designed or customized optical modules.

[0072] Understandably, the target overclocking rate selected using the above method can break through the original physical speed limit (generally, the physical speed limit is affected by factors such as temperature, fiber length, and signal quality), compensating to some extent for the bandwidth consumed by data packet forwarding, thereby increasing the actual effective forwarding bandwidth of user data packets. For example, the standard baud rate of a 25G optical port is 25.781250G, and the target overclocking rate selected using the above method can configure the optical port speed to any of 27.34375G, 27.78125G, or 28.125000G.

[0073] For example, when the optical module inserted into the 10G optical port is 10G, the target overclocking rate selected by the above method can reach 11G or 12G.

[0074] In some embodiments, S104 includes the following steps: Select the overclocking rate with the largest value from the set of overclocking rates and determine it as the target overclocking rate, and then communicate with the target terminal based on the target overclocking rate.

[0075] In the application, the effective overclocking rate with the largest value is selected from the set of overclocking rates and determined as the target overclocking rate. Then, based on the maximum effective overclocking rate (i.e. the target overclocking rate) supported by the current switching equipment and located within the target frequency range supported by the target optical module, communication is carried out with the target terminal.

[0076] In some embodiments, after S104, the following steps are further included: Start the timer to obtain the timer duration; When the timing duration reaches the preset threshold, return to execute the steps to obtain the target frequency range of the target optical module and subsequent steps.

[0077] In applications, the frequency range supported by the optical module can change due to external environmental factors (e.g., ambient temperature, fiber length, signal quality, etc.) (e.g., supporting a higher frequency range or a lower frequency range). Based on this, a preset threshold is set. When a target overclocking rate is selected and communication with the target terminal is initiated based on the target overclocking rate, a timer is started to obtain the corresponding timing duration. When the timing duration reaches the preset threshold, the process returns to obtain the target frequency range of the optical module and subsequent steps, so as to dynamically update the target overclocking rate based on the updated target frequency range, improve the forwarding bandwidth of user data packets, and thus improve data transmission efficiency.

[0078] The preset threshold can be set according to actual needs. For example, the preset threshold can be set to 10s, 30s, or 2h.

[0079] As an example and not a limitation, when the aforementioned physical link interruption is detected, the steps of obtaining the target frequency range of the target optical module and subsequent steps may be stopped.

[0080] The communication method provided in this application, upon detecting physical link connectivity, obtains the target frequency range of the target optical module, acquires at least one overclocking rate within the target frequency range, and determines the receiving channel state and transmitting channel state of the target optical module corresponding to each overclocking rate. Based on the receiving channel state and transmitting channel state of the target optical module corresponding to each overclocking rate, an overclocking rate set including at least one effective overclocking rate is constructed. A target overclocking rate is selected from the overclocking rate set, and communication with the target terminal is performed based on the target overclocking rate. This achieves adaptive selection of effective rates based on the states of the switching equipment and optical modules, improving the forwarding bandwidth of user data packets and thus enhancing data transmission efficiency.
