Background
In the past Ethernet technical standard, the Ethernet service rate and the rate of a PHYSICAL interface (PHYSICAL) are always matched and consistent, and the rates of the Ethernet service rate and the PHYSICAL interface (PHYSICAL) are synchronously developed. However, when the ethernet service rate is increased to over 100GE, the speed development of the physical interface encounters a bottleneck, the speed increase is gradually slowed down, the price of the physical interface is also slowly reduced, and the cost performance of the high-speed physical interface is reduced. For example, the price of the optical module with the 400GE rate exceeds the price of 4 optical modules with the 100GE rate, which causes the commercial cost performance of the optical module with the 400GE rate to be reduced.
FLEXIBLE ETHERNET (FLEXIBLE ETHERNET) technology enables the decoupling of traffic rate and physical channel rate, the rate of the physical interface may no longer be equal to the rate of the customer traffic, and the rate of the physical interface is FLEXIBLE.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
referring to fig. 1, fig. 1 is a schematic diagram of a flexible ethernet networking according to an embodiment of the present invention; wherein, the first device 11 has a physical interface 1 and a physical interface 3, and the second device 12 has a physical interface 2 and a physical interface 4; physical interface 1 is connected to physical interface 2, and physical interface 3 is connected to physical interface 4. The flexible ethernet 5 may bind a first physical channel formed by the physical interfaces 1 and 2 and a second physical channel formed by the physical interfaces 3 and 4 into a virtual logical channel for service delivery.
Referring to fig. 2, fig. 2 is a flowchart of a method for responding to a link failure in a flexible ethernet according to an embodiment of the present invention;
s201, when the first physical interface is detected to be out of order, time slot configuration information of a client port bound by the first physical interface is obtained.
It should be noted that, in the embodiment of the present application, the first physical interface does not mean a specific physical interface, and in the embodiment of the present application, any failed physical interface is referred to as a first physical interface; of course, it is not excluded that there are other failed physical interfaces in the flexible ethernet system in this embodiment. In this embodiment, the technical solution provided by the present invention is described in terms of one of the physical interfaces, and when a plurality of physical interfaces have a failure, the link failure can be responded through the steps provided by this embodiment. Regardless of the number of failing physical interfaces, the present invention is within the scope of protection without departing from the inventive concept. In the flexible ethernet system, the traffic of one client port may be transmitted through one or more physical interfaces, and one physical interface may also transmit the traffic of one or more client ports; the binding of the physical interface to the client port may be configured. It should be noted that, in the embodiment of the present application, a client port bound to a physical interface is only a client port that may have a transmission relationship with the physical interface in configuration, the bound physical interface and the client port are not necessarily performing message transmission, and in actual application, the client port may only pass through a part of the bound physical port to perform traffic.
And the time slot occupied by the client port at each physical interface can be reflected through the time slot configuration information.
S202, removing the time slot corresponding to the first physical interface from the currently used time slot of the client port bound by the first physical interface to obtain the residual time slot.
If the first physical interface fails, if the service packet is still transmitted through the time slot of the first physical interface, the data carried through the time slot corresponding to the first physical interface cannot be successfully communicated, and finally, the receiving end lacks corresponding data and cannot assemble a complete service packet.
In this implementation, the time slot of the first physical interface with the fault is removed from the time slots used by the client ports corresponding to the first physical interface, so as to obtain the remaining time slots; similarly, in other implementation processes, a plurality of physical interfaces may fail, and the time slots of the failed physical interfaces are respectively removed at the corresponding client ports, and finally, the available remaining time slots are obtained.
S203, updating the time slot configuration information according to the residual time slots, and sending and/or receiving the service message from the physical interface which is not failed according to the updated time slot configuration.
Because the time slot of the failed physical interface is removed, and the remaining time slots are the time slots of the physical interfaces which do not fail, the remaining time slots can be used for continuously transmitting the service message.
And after the residual time slot is obtained, carrying out re-planning on the configuration of the time slot according to the residual time slot, and updating the time slot configuration information, wherein the time slot configured by each client port can be used at the moment, and the transmission of the service message is realized by configuring a physical interface which never sends a fault according to the updated time slot.
Optionally, because the first physical interface has failed and the timeslot of the failed physical interface has been removed in the timeslot configuration, the resources allocated on the first physical interface are recovered before sending and/or receiving the service packet from the physical interface that has not failed according to the updated timeslot configuration.
It should be noted that, the process of sending and/or receiving the service packet from the non-failed physical interface according to the updated timeslot configuration may be: and the first equipment transmits the service message from the physical interface which is not failed according to the updated time slot configuration, at the moment, the second equipment only receives the service message from the physical interface which is not failed, extracts the transmission time slot from the overhead message after the second equipment receives the service message, and assembles the service message according to the new transmission time slot, thereby obtaining the correct service message.
Optionally, after detecting that the first physical interface fails, the state of the first physical interface is recorded and updated in the client, so that the state of the physical interface can be known uniformly in the flexible ethernet system, and thus, the state information can be unified among the layers in the system. After the state of the physical interface is updated, the time slot configuration information is checked according to the updated state information, and the time slot configuration information is adjusted, so that the time slot configuration information is ensured to be consistent with the state information of the physical interface. It should be understood that when the slot configuration information has been adjusted or does not need to be updated, it is not adjusted.
Optionally, after it is detected that the first physical interface is recovered to normal, the state information of the first physical interface is updated. Correspondingly, adding the time slot corresponding to the first physical interface into the currently used time slot of the client port bound to the first physical interface to obtain a recovery time slot. It should be understood that, although the first physical interface at this time recovers from the failure and does not perform transmission of data existing in the client port, the client port bound to the first physical interface can be obtained according to the original configuration of the system. And updating the time slot configuration information according to the recovery time slot to obtain a second time slot configuration, and transmitting the service message from the link where the recovered first physical interface is located according to the second time slot configuration. It should be understood that the second timeslot configuration is not necessarily a default timeslot configuration of the system, because in an actual process, there may be other physical interfaces that have failed and are not recovered, and the second timeslot configuration in this embodiment is only a timeslot configuration obtained after recovering a timeslot corresponding to the first physical interface based on the current timeslot configuration; however, in some implementations, if only one physical interface fails and recovers, the second timeslot configuration obtained after recovery is the initial default timeslot configuration.
Similarly, after the first physical interface is recovered, the first device sends a service message from an interface which does not have a fault and comprises the first physical interface, the second device receives the service message at a second physical interface connected with the first physical interface, extracts a multiframe from the overhead message, extracts a new sending time slot from the overhead message after the multiframe is locked, and assembles the service message according to the new sending time slot, so that a correct service message is obtained. In some implementations of this embodiment, the time slots are automatically added back to the time slot configuration after the restoration of the physical interface that detected the failure, restoring bandwidth.
It should be noted that, in this embodiment, the transmission directions of the first device and the second device are bidirectional, and the above description only describes that, when the second device sends a service packet to the first device, the steps performed are similar, and are not described herein again.
According to the method for responding to the link failure by the flexible Ethernet, provided by the embodiment of the invention, when the first physical interface is detected to have a failure, the time slot corresponding to the first physical interface is removed from the currently used time slot of the client port bound to the first physical interface, the time slot configuration information is updated according to the remaining time slots, and the updated time slot configuration is used for transmitting the service message from the physical interface which has not failed; when the link fails, the bandwidth is rapidly adjusted, the transmission of the service is ensured, and no extra time slot is required to be configured, so that the speed of responding to the link failure by the flexible Ethernet is improved, and the resource consumption is reduced.
Example two:
referring to fig. 3, fig. 3 is a specific flowchart of a method for responding to a link failure by a flexible ethernet according to a second embodiment of the present invention;
s301, detecting that the physical interface fails.
In this embodiment, the transmission directions of the first device 11 and the second device 12 are bidirectional, the angle of the station in this embodiment when the first device 11 sends the service packet is expressed, and the steps performed when the second device 12 serves as a sending end to send the service packet are similar, which is not described herein again.
If the physical interface 1 fails, correspondingly, the link where the physical interface 1 is located fails, and the physical interface 2 cannot normally transmit the service message.
S302, inquiring time slot configuration information of a client port bound by a fault physical interface, and recording and updating the state of the physical interface.
After the fault information of the physical interface 1 is acquired, the client port information of data transmitted through the physical interface 1 is inquired, the time slot configuration information of the client port is acquired, the state information of the physical interface 1 is recorded, the state of the physical interface 1 is updated in the client, and at the moment, the physical interface 1 is in fault and the state is updated to DOWN.
When inquiring the time slot configuration information, other configuration information can be obtained to assist the response to the link failure.
S303, removing the time slot corresponding to the failed physical interface from the time slot used by the client port to obtain the residual time slot.
Acquiring time slot configuration information of a client port, and removing a time slot corresponding to the physical interface 1 from the time slot used by the client port to obtain a remaining time slot, wherein the remaining time slots are all normally available time slots, namely, the time slot corresponding to the physical interface 3, under the condition that only one link fails as in this embodiment. When a plurality of links fail, the time slots corresponding to the failed physical interfaces in the time slots used by the client terminal ports are respectively removed, and available residual time slots are obtained.

And S305, applying the adjusted time slot to the time slot configuration.
And updating the adjusted sending time slot into the time slot configuration information.
S306, the first device sends the service message according to the new time slot configuration.
The first device 11 sends the service packet according to the timeslot configuration information, and since the timeslot configuration information has been updated to send the service packet using the remaining timeslot, in this embodiment, the remaining timeslot is a timeslot corresponding to the physical interface 3, the service packet sent by the first device 11 is only sent through the physical interface 3.
S307, the second equipment obtains the correct service message.
Accordingly, the second device 12 receives the service packet only from the physical interface 4 connected to the physical interface 3. After the second device 12 receives the service packet, a new sending timeslot is extracted from the overhead packet, and the second device 12 can assemble a correct service packet according to the new sending timeslot.
Referring to fig. 4, fig. 4 is a specific flowchart of a method for responding to a link failure by a flexible ethernet according to a second embodiment of the present invention; the following describes steps of link recovery in this embodiment with reference to the flexible ethernet networking structure shown in fig. 1 and fig. 4:
s401, detecting the link recovery.
Preferably, after detecting that the link is recovered, in order to ensure that the link is more stable and does not make a quick response, the following steps are performed after the link is completely recovered to be normal.
S402, updating the state of the physical interface in the client.
In the client, the state of the physical interface 1 is updated to UP, i.e. the physical interface 1 works normally.
And S403, adding the time slot corresponding to the recovered physical interface into the time slot used by the bound client port to obtain a recovered time slot.
The time slot currently used by the client port is the time slot corresponding to the physical interface 3, at this time, the state of the physical interface 1 bound by the client port is updated to be UP, and the recovery time slot is obtained by adding the time slot corresponding to the physical interface 3 and the time slot corresponding to the physical interface 1.
And S404, adjusting the time slot.
And aiming at the client port bound by the physical interface 1, adjusting the sending time slot of the client port according to the recovery time slot.

The first device 11 sends the service packet according to the timeslot configuration information, and since the timeslot configuration information is restored to the timeslot transmission service packet using the physical interface 1 and the physical interface 3, the service packet sent by the first device 11 is sent through the physical interface 1 and the physical interface 3.
S407, the second device obtains the correct service message.
Accordingly, the second device 12 receives the service packet from the physical interface 2 and the physical interface 4. After receiving the service message, the second device 12 extracts a multiframe from the overhead message, and after locking the multiframe, extracts the latest sending time slot from the overhead message, and according to the latest sending time slot, the second device 12 assembles a correct service message.
