Detailed Description
The embodiment of the application provides a port mode switching method and related equipment thereof, which are used for switching the port modes of equipment at two ends of a link when the equipment at two ends is ready to switch the port modes, so that the time of link failure caused by different port modes at two ends of the link during switching is reduced in the switching process.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The method and the device are mainly applied to a scene that an ETH mode and a FlexE mode of a device port are mutually switched. Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a real-time example of the present application, when ports of devices (a first device and a second device) at two ends of a link need to be switched to a state to be activated (i.e., a first port state in this embodiment, at this time, a device port does not yet really switch a mode, and the port still maintains an original mode), and when it is detected that port states of the ports at the two ends of the device are consistent and a negotiation is successful, the device ports at the two ends of the link switch a mode again, so that a link failure caused by the fact that the port modes at the two ends of the link are different in a switching process can be avoided. It should be noted that, the port mentioned in this embodiment is a port through which the first device and the second device perform communication link.
Referring to fig. 2, an embodiment of a method for switching a port mode in an embodiment of the present application includes:
201. the first device receives a handover instruction.
In this embodiment, if the current port mode of the first device is the first mode and needs to be switched to the second mode, the first device receives a switching instruction, where the switching instruction instructs the port mode of one port in the first device to be switched from the first mode to the second mode, where the switching instruction may be manually input on the first device, may also be sent to the first device by another device, may also be automatically generated by the first device at a predetermined time, and a specific sending manner is not limited here.
In the present application, the first mode is an ETH mode, the second mode is a FlexE mode, or the first mode is a FlexE mode, the second mode is an ETH mode, and specific modes of the first mode and the second mode are not limited herein.
202. The first device marks the state of the port of the first device as a first port state.
In this embodiment, after the first device receives the switching instruction, the first device may mark the state of the port corresponding to the switching instruction as a first port state, and record a state bit, where the first port state indicates that the first device is in a state in which the first mode is to be switched to the second mode.
In this embodiment, the status bit is recorded by, for example, 3 bits (bits), and in the first bit, a status bit "0" indicates a port status of the port mode to be switched from the first mode to the second mode; the status bit "1" represents a port status in which the port mode is to be switched from the second mode to the first mode; in the second and third bits, the status bit "00" represents the to-be-activated state (in this embodiment, the to-be-activated state is the first port state, and in other embodiments, the to-be-activated state may also be other port states, for example, a port state to be switched from the second mode to the first mode); the status bit "01" indicates that the second device has switched to the to-be-activated state (the first port state), but has not negotiated configuration parameters with the second device; the status bit "10" indicates that the second device has switched to the state to be activated (the first port state), but when the second device performs configuration parameter negotiation, the negotiation fails; the status bit "11" indicates that the second device has switched to the standby state and the negotiation is successful when performing the configuration parameter negotiation with the second device.
203. The first device sends a negotiation request message to the second device.
In this embodiment, after the first device marks the state of the port as the first port state, the first device sends a negotiation request message to the second device. In this embodiment, various messages used in communication between the first device and the second device are, for example, in a format of a FlexE Overhead Frame (Overhead Frame), or in an ethernet message format, and a specific format is not limited here. The status bit may be inserted into the message, for example, the status bit may be inserted into a FlexE overhead frame, the format of the overhead frame may be as shown in fig. 3, a part of bits in a Reserved (Reserved) bit segment of the overhead frame may be used as the status bit (for example, a second Reserved bit segment, which takes 3 bits), and the format of the FlexE overhead frame may refer to descriptions of an Optical Internet Forum (OIF) about a FlexE overhead frame and a multiframe (multiframe). The negotiation request message includes first status information (in this embodiment, the first status information may have a status bit of "000"), where the first status information indicates that the status of the port of the first device is the first port status, and the second device is a device in communication link with the first device.
204. The second device determines whether the first port state is consistent with the second port state, if so, step 205 is executed, and if not, the processing is stopped or a negotiation failure message is returned to the first device.
In this embodiment, after the second device receives the negotiation request message sent by the first device, the first port state information in the negotiation request message may be obtained, so as to determine whether the first port state indicated by the first state information is consistent with the state of the port of the second device marked by the second device (i.e., the second port state), which may specifically be: it is determined whether the status bit in the negotiation request is consistent with the status bit marked in the second device, both being "000".
If the first port state is judged to be inconsistent with the second port state of the second device, the second device may not return any message, keeps the original port state, and also returns a message of state negotiation failure, and after receiving the negotiation failure message, the first device may start negotiation again in a subsequent fixed period; and if the first port state is consistent with the second port state, the second equipment returns a negotiation response message to the first equipment. The negotiation response message indicates that the state of the port of the second device is the first port state, and the negotiation response message may include the same state bit as that in the negotiation request message so as to indicate that the state of the port of the second device is also the first port state. The negotiation response message may also comprise an indication field indicating that the status of the port of said second device is the same as the status of the first port, but not comprising the status bit itself.
205. The second device returns a negotiation response message to the first device.
In this embodiment, when the first port state is consistent with the second port state, a negotiation response message is returned to the first device, where the corresponding message indicates that the port state of the second device is also the first port state (that is, the second port state is consistent with the first port state), and then the second device may change the second and third bit state bits of the state bit marked on the self device from "00" to "01", and when the first device receives the negotiation response message, the second and third bit state bits of the state bit marked on the self device may also be changed from "00" to "01".
It should be noted that the case of switching from FlexE to ETH does not involve negotiation between the FlexE Group Number and the FlexE physical connection Number (PHY Number), i.e. steps 206 to 212 do not need to be executed, step 213 is directly executed, i.e. when the first port status is consistent with the second port status and the second device returns a negotiation response message to the first device, i.e. it indicates that the port switching of the first device and the second device has been successfully negotiated, at this time, the first device and the second device may directly change the status bits of the second and third bits of the marked status bits from "00" to "11", and at the same time, may switch the port mode from FlexE to ETH.
206. The first device sends the first device priority to the second device.
In this embodiment, when the first device learns that the state of the port of the first device is consistent with the state of the port of the second device, the first device sends a first device priority to the second device, where the first device priority may be a MAC address (which may be a multiplexed port MAC address) of the port of the first device or a device priority defined by a user or a device, and a specific form of the first device priority is not limited here.
The priority of the first device may be sent in a FlexE overhead frame format, or in a customized ethernet format, and the specific sending format is not limited here.
207. The second device sends the second device priority to the first device.
In this embodiment, after the second device returns the negotiation response message to the first device, the second device priority is sent to the first device, where the second device priority may be a MAC address of a port of the second device (may multiplex the port MAC address), or may be a device priority customized by a user or a device, and a specific form of the second device priority is not limited here.
The priority of the second device may be sent in a FLexE overhead frame format, or may be sent in a self-defined message conforming to an ethernet format, and the specific sending format is not limited here.
208. The first device sends the first configuration parameters to the second device.
It should be noted that, when both the first device and the second device send their own priorities to the opposite end, both ends may determine the priorities of the first device and the second device, where the one end with the higher priority is used as a sender (active end) of the configuration parameter, and the other end is a receiver (passive end) of the configuration parameter.
It should be noted that step 206 and step 207 may be omitted, that is, the first device and the second device do not perform the interaction of the priority related information, and directly perform the negotiation of the configuration parameters. For example, the first device does not determine the priority, and directly sends the configuration parameters to the second device to start negotiation, and the second device automatically completes negotiation as a passive party after receiving the configuration parameters.
It should be noted that the configuration parameters, the first configuration parameters, and the second configuration parameters mentioned in the embodiments of the present application include: FlexE Group Number and FlexE PHY Number.
209. The second device determines whether there is a configuration parameter that is consistent with the first configuration parameter and is not used in the second device, if not, step 210 is executed, and if so, step 212 is executed.
For example, the first device sends parameters with a FlexE Group Number of 3 and a FlexE PHY Number of 9, the second device determines whether the configuration parameters with the FlexE Group Number of 3 and the FlexE PHY Number of 9 on the second device have been used, that is, the second device determines whether the physical connection with the Group Number of 3 and the PHY Number of 9 on the second device has been used.
210. The second device sends a negotiation failure message to the first device.
In this embodiment, when the configuration parameter that is consistent with the first configuration parameter and is not used does not exist in the second device, the second device may feed back a negotiation failure message to the first device. The second and third bit status bits in the negotiation failure message may be "10" to indicate that the FlexE Group Number and PHY Number negotiation failed. The second device may change the second and third bit status bits of the self-flagged status bit from "01" to "10".
211. And the first equipment sends the second configuration parameters to the second equipment.
In this embodiment, after the first device receives the negotiation failure message sent by the second device, the second and third bit status bits of the status bit marked by the first device may also be changed from "01" to "10", and a second configuration parameter is sent to the second device, where the second configuration parameter is an unused configuration parameter in the first device except for a configuration parameter (first configuration parameter) already sent.
It should be noted that, after the second device receives the second configuration parameter, it is determined whether a configuration parameter that is consistent with the second configuration parameter and is not used exists in the second device, and if the configuration parameter does not exist, a negotiation failure message is sent to the first device. After the first device receives the negotiation failure message, it reselects the unused configuration parameters that have not been sent to the second device until the second device finds the configuration parameters that are consistent with the configuration parameters of the first device, and then performs step 212. If the second device does not find the configuration parameters consistent with the configuration parameters of the first device after the first device polls all the unused configuration parameters, the negotiation may be stopped at this time.
212. The second device sends a negotiation success message to the first device.
In this embodiment, when the second device has the configuration parameter that is consistent with the first configuration parameter or the second configuration parameter and is not used, a negotiation success message may be sent to the first device, and the status bits of the second and third bits in the negotiation success message may be "11" to indicate that the FlexE Group Number and the PHY Number negotiate successfully. The second device may change the state bits of the second and third bits of the state bit from "01" to "11", and after receiving the negotiation success message, the first device may also change the state bits of the second and third bits of the self-marked state bit from "01" to "11".
It should be noted that, when the configuration parameters are not successfully negotiated in the first round, the status bits of the second and third bits of the status bits marked by the first device and the second device themselves are changed from "10" to "11".
213. The first device and the second device switch from the first mode to the second mode.
In this embodiment, when the first device and the second device are both in the first port state and the negotiation of the configuration parameters of the first device and the second device is successful, the first device and the second device are switched from the first mode to the second mode.
It should be noted that, in this embodiment, after the first device and the second device are switched to the second mode, the first device and the second device set the configuration parameters negotiated according to steps 206 to 212 as the configuration parameters of the ports of the first device and the second device. For example, when the port of the first device and the port of the second device are switched from the ETH mode to the FlexE mode, the negotiated FlexE Group Number and PHY Number may be used to perform FlexE communication, which solves the problem that the FlexE Group numbers and PHY numbers of the devices at both ends need to be manually set when the port mode is switched from the ETH mode to the FlexE mode, simplifies the deployment process, improves the processing efficiency, and helps to avoid link failure caused by manual configuration omission or manual configuration inconsistency.
It should be noted that steps 206 to 212 may be omitted, that is, when the first port status and the second port status are consistent, the first device and the second device communicate with each other using the pre-agreed configuration parameters, and when the second mode is the FlexE mode, the configuration parameters, such as the FlexE Group Number and the PHY Number to be used, need to be set in advance on the first device and the second device, respectively, so that the communication in the FlexE mode can be started quickly without performing priority determination and configuration parameter negotiation.
In the embodiment of the application, the first device marks the state of the port of the first device as a first port state, wherein the first port state is a state in which a first mode is to be switched to a second mode; then the first device sends a negotiation request message to the second device, wherein the negotiation request message contains first state information, and the first state information indicates that the state of the port of the first device is a first port state; then the first device receives a negotiation response message sent by the second device, wherein the negotiation response message indicates that the state of the port of the second device is the first port state; and finally, the first equipment switches the mode of the port into a second mode according to the negotiation response message. Due to the fact that the to-be-switched state is set, the port modes of the devices at the two ends of the link can be switched simultaneously when the devices at the two ends are ready to switch the port modes, and therefore the time of link failure caused by the fact that the port modes at the two ends of the link are different in the switching process is shortened.
