Description

Interface configuration method and device

Technical Field

The present application relates to the field of communications, and in particular, to an interface configuration method and apparatus.

Background

The communication device may include a physical interface, and the physical interface on the communication device may be configured in an Ethernet (Eth) mode or a Flexible Ethernet (FlexE) mode. When two physical interfaces in a neighboring relationship with each other communicate, the two physical interfaces may both be configured in an Eth mode or a FlexE mode. However, if one of the physical interfaces is configured in the FlexE mode and the other physical interface is configured in the Eth mode, the two physical interfaces cannot normally communicate.

Currently, when two physical interfaces in a neighboring relationship with each other are configured in a FlexE mode and the other physical interface is configured in an Eth mode, a user, such as an operation and maintenance person, is required to manually configure one of the two physical interfaces so that the two physical interfaces can normally communicate, but this approach is inefficient.

Disclosure of Invention

The embodiment of the application provides an interface configuration method, which can improve the configuration efficiency of a physical interface.

In a first aspect, an embodiment of the present application provides an interface configuration method, which may be performed by a first communication device. The first communication device includes a first port that may be used to communicate with a second port of a second communication device. In one example, the first communication device may determine a chip operating mode of the second port, and when the chip operating mode of the second port is determined to be an Eth mode, the first communication device may switch the chip operating mode of the first port from a FlexE mode to the Eth mode. In this way, the chip operating mode of the first port and the chip operating mode of the second port are both Eth modes, and therefore the first port and the second port can communicate normally. Therefore, by the aid of the scheme, a user does not need to manually configure the chip working mode of the first port, the first communication device can switch the chip working mode of the first port according to the chip working mode of the second port, and efficiency of configuring the first port is improved.

In one implementation, it is contemplated that the first communication device may receive a FlexE overhead frame of the second communication device if a FlexE communication is established between the first communication device and the second communication device. Therefore, in an implementation manner, if the first communication apparatus does not receive the FlexE overhead frame sent by the second communication apparatus within a preset time, it is indicated that FlexE communication is not established between the first communication apparatus and the second communication apparatus, and at this time, the first communication apparatus may determine that the chip operating mode of the second port is an Eth mode.

In one implementation manner, after the first communication device configures the chip operating mode of the first port to the Eth mode, the first communication device may further receive first indication information sent by the second communication device, where the first indication information is used to indicate that the first communication device configures the chip operating mode of the first port to the FlexE mode. As such, in one example, the first communication device may configure the chip operating mode of the first port to the FlexE mode, thereby causing the first port to operate in the FlexE mode. In this case, if the second port is also operating in the FlexE mode, FlexE communication can be established between the first communication device and the second communication device.

In one implementation, the first indication information is a remote failure RF indication information. In one example, when the first communication device receives the RF indication from the second communication device, the first communication device may configure the chip operation mode of the first port to the FlexE mode.

In one implementation manner, the first indication information includes O of a first ethernet frame sent by the second communication device₀Code blocks. In one example, when a first communication device receives a first ethernet frame from a second communication device, O of the first ethernet frame may be extracted₀Value of code block and O of first Ethernet frame₀When the value of the code block is a preset value, for example, 0X05, the chip operation mode of the first port is configured to be a FlexE mode.

In one implementation, the first indication information may be carried in an extended TLV field of the first ethernet frame sent by the second communication device. In one example, when the first communication device receives the first ethernet frame from the second communication device, the chip operation mode of the first port may be configured to be the FlexE mode according to the extended TLV field in the first ethernet frame.

In one implementation, the first communication device may further instruct the second communication device to configure the chip operation mode of the second port to a FlexE mode. For example, in one example, the first communication device may instruct the second communication device to configure the chip operating mode of the second port to the FlexE mode before configuring the chip operating mode of the first port to the FlexE mode. Then, the first communication device configures the chip operation mode of the first port to a FlexE mode. The second communication device may configure the chip operation mode of the second port to the FlexE mode based on the instruction of the first communication device. In this way, FlexE communication is established between the first port and the second port.

In one implementation, the first communication device may instruct the second communication device to configure the chip operation mode of the second port to the FlexE mode by periodically sending second indication information to the second communication device within a predetermined time. Wherein the second indication information is used for indicating the second communication device to configure the chip operating mode of the second port to a FlexE mode. And periodically sending second indication information to the second communication device within a preset time, wherein the second indication information is used for ensuring that the second communication device can receive the second indication information, so that the second communication device is ensured to configure the chip working mode of the second port into a Flexe mode, and further, Flexe communication can be established between the first port and the second port.

In one implementation, the second indication information is a remote failure RF indication information. In an example, when the second communication device receives the RF indication information from the first communication device, if the port configuration mode of the second port is the FlexE mode and the chip operation mode of the second port is the Eth mode, the second communication device may configure the chip operation mode of the second port as the FlexE mode.

In one implementation, the second indication information is a station numberO of fourth Ethernet frame transmitted by the first communication device₀Code blocks. In one example, O of a fourth ethernet frame transmitted by the first communication device to the second communication device₀The code block may have a value of 0X 05.

In one implementation, the second indication information may be carried in an extended TLV field of a fourth ethernet frame sent by the first communication device. In one example, when the second communication device receives the fourth ethernet frame from the first communication device, the chip operation mode of the second port may be configured to be the FlexE mode according to the extended TLV field in the first ethernet frame.

In an implementation manner, after the first communication device switches the chip operating mode of the first port from the Eth mode to the FlexE mode, the chip operating mode of the second port may be periodically detected, and when the chip operating mode of the second port is different from the chip operating mode of the first port, the chip operating mode of the first port is reconfigured, so that the chip operating mode of the first port and the chip operating mode of the second port are consistent. For example, in one example, when the first communication device determines that the chip operating mode of the second port is an Eth mode, the first communication device may switch the chip operating mode of the first port from a FlexE mode to the Eth mode.

In one implementation, after the first communication device switches the chip operating mode of the first port from the FlexE mode to the Eth mode, if the first communication device determines that the chip operating mode of the second port is the FlexE mode, the first communication device may switch the chip operating mode of the first port from the Eth mode to the FlexE mode.

In one implementation, when the chip operating mode of the first port is an Eth mode, if the chip operating mode of the second port is also an Eth mode, the first port may receive a block lock (block lock) signal from the second port. Therefore, if the first communication device does not receive the block lock signal sent by the second communication device within the preset time period, the first communication device may determine that the chip operating mode of the second port is the FlexE mode.

In one implementation, when the chip operation mode of the first port is an Eth mode, if the chip operation mode of the second port is also an Eth mode, the first port may receive an alignment marker lock (alignment marker lock) signal from the second port. Therefore, if the first communication device does not receive the alignment marker lock signal sent by the second communication device within the preset time period, the first communication device may determine that the chip operating mode of the second port is the FlexE mode.

In one implementation, the first communication device may be based on O transmitted by the second communication device₀The value of the code block to determine the chip mode of operation of the second port. Wherein: when the second communication device transmits O₀When the code block has a value of 0X05, the first communication device may determine that the chip operation mode of the second port is the FlexE mode.

In an implementation manner, when the chip operating mode of the first port is an Eth mode, the first communication device may determine the chip operating mode of the second port by sending a second ethernet frame to the second communication device, where the second ethernet frame is used to determine the chip operating mode of the second port. If the first communication device does not receive the response of the second communication device to the second ethernet frame, the first communication device may determine that the chip operation mode of the second port is the FlexE mode.

In one implementation, the second ethernet frame includes an extended type length value, TLV, field, and the extended TVL field includes third indication information, and the third indication information is used to determine a chip operation mode of the second port.

In one implementation, the port configuration mode of the first port is a FlexE mode. When the port configuration mode of the first port is the FlexE mode, it is described that the first port may be used as an Eth interface or a FlexE interface. In other words, the chip operation mode of the first port may be configured as either the FlexE mode or the Eth mode. If the port configuration mode of the first port is the Eth mode, the first port may only be able to serve as an Eth interface, and at this time, the chip operation mode of the first port may not be configured to be the FlexE mode.

In a second aspect, embodiments of the present application provide an interface configuration method, which may be performed by a first communication device. The first communication device includes a first port that may be used to communicate with a second port of a second communication device. In one example, the first communication device may receive first indication information sent by the second communication device, where the first indication information is used to instruct the first communication device to configure the chip operating mode of the first port to the FlexE mode. After receiving the first indication information, the first communication device may switch the chip operating mode of the first port from the Eth mode to the FlexE mode. Therefore, by the aid of the scheme, a user does not need to manually configure the chip working mode of the first port, the first communication device can configure the chip working mode of the first port according to the first indication information sent by the second communication device, and efficiency of configuring the first port is improved.

In other words, when the chip operating mode of the second port is different from the chip operating mode of the first port, the first communication device may adjust the chip operating mode of the first port, so that the adjusted chip operating mode of the first port is the same as the chip operating mode of the second port, thereby enabling the first port and the second port to communicate normally. Therefore, by the aid of the scheme, a user does not need to manually configure the chip working mode of the first port, the first communication device can switch the chip working mode of the first port according to the chip working mode of the second port, and efficiency of configuring the first port is improved.

Therefore, in an implementation manner, when the chip operating mode of the first port is the FlexE mode, if the first communication device does not receive the FlexE overhead frame sent by the second communication device within the preset time, it is indicated that FlexE communication is not established between the first communication device and the second communication device, and at this time, the first communication device may determine that the chip operating mode of the second port is the Eth mode.

In one implementation manner, after the first communication device configures the chip operating mode of the first port to the Eth mode, the first communication device may further receive first indication information sent by the second communication device, where the first indication information is used to indicate that the first communication device configures the chip operating mode of the first port to the FlexE mode. As such, in one example, the first communication device may configure the chip operating mode of the first port to the FlexE mode according to the first indication information, thereby causing the first port to operate in the FlexE mode.

Detailed Description

The embodiment of the application provides an interface configuration method, which is used for improving the configuration efficiency of a physical interface.

For ease of understanding, the relevant contents of Eth and FlexE will be described first.

For a physical interface, the physical interface may be configured as an Eth mode, and may also be configured as a FlexE mode. For convenience of description, in the following description of the present application, a physical interface operating in the FlexE mode is referred to as a "FlexE interface", and a physical interface operating in the Eth mode is referred to as an "Eth interface". Referring to fig. 1a and fig. 1b, fig. 1a is a schematic structural diagram of an Eth interface provided in an embodiment of the present application, and fig. 1b is a schematic structural diagram of a FlexE interface provided in the embodiment of the present application.

As shown in fig. 1a, the Eth interface includes a Media Access Control (MAC) layer, a coordination sublayer (RS), a Physical Coding Sublayer (PCS), a Physical Medium Attachment (PMA) sublayer, and a Physical Medium Dependent (PMD) sublayer. As shown in fig. 1b, the FlexE interface includes one more FlexE shim (shim) between the MAC layer and the PCS, in addition to the MAC layer, the RS, the PCS, the PMA sublayer and the PMD sublayer.

It should be noted that fig. 1a and 1b are only illustrated for convenience of understanding the structural difference between the Eth interface and the FlexE interface, and do not limit the embodiments of the present application. In some embodiments, the structure of the Eth interface and the FlexE interface is not limited to that shown in fig. 1a and 1 b.

Illustratively, the processing mode of the Eth interface to the packet is as follows: the PCS receives the data and directly transmits the data to the MAC layer, and the MAC layer assembles the data into an Eth message.

Illustratively, the FlexE interface has two message processing modes. The first processing mode is as follows: and the PCS receives the data and transmits the data to Flexe shim, the Flexe shim is transmitted to the MAC, and the MAC assembles the data into an Eth message. The second processing mode is as follows: the PCS of the Flexe interface 1 receives data and sends the data to the Flexe shim of the Flexe interface 1, the Flexe shim of the Flexe interface 1 sends the data to the Flexe shim of the Flexe interface 2, and the Flexe shim of the Flexe interface 2 sends the data from the PCS of the Flexe interface 2 to a link. The Flexe interface 1 and the Flexe interface 2 are in a neighbor relation with each other, and communication can be carried out between the two interfaces. The FlexE interface may determine, according to the configuration, to process the packet in one of the above two manners.

When two physical interfaces which are in a neighbor relation with each other communicate, if one of the two physical interfaces is configured in a FlexE mode and the other physical interface is configured in an Eth mode, the two physical interfaces cannot communicate normally. This is because, for a packet from some other device, for example, a user device, the Eth interface processes the packet in a different manner from the FlexE interface. In one example:

when the Eth interface sends a message, for a message from a certain user equipment, the Eth interface cuts the message into 64-bit data, adds 2 bit synchronization heads in front of the data to form a 66-bit information block (block), and then sends the 66-bit block to a link in sequence. For example, after the Eth interface processes the packet, 4 blocks are obtained, and then the Eth interface first sends block1 to the link, then sends block2 to the link, and then sends block3 and block4 to the link in sequence. For this case, the data sent by the Eth interface to the link is: block1| block2| block3| block 4. Where "a | B" indicates that two bit streams a and B are concatenated in sequence.

When a Flexe interface sends a message, the Flexe shim of the Flexe interface cuts the message into 64-bit data, 2 bit synchronization heads are added in front of the data to form 66-bit blocks, and the blocks are inserted into specific slots. For example, the FlexE interface comprises 4 slots, where slot 1 and slot 3 are used to forward messages from the user equipment 1, and slot 2 and slot 3 are not yet allocated. Then the FlexE interface processes the packet from the user equipment 1 to obtain 2 blocks, which are respectively block5 and block6, and then the FlexE interface schedules block5 to slot 1 for forwarding, schedules an empty block to slot 2 for forwarding, schedules block6 to slot 3 for forwarding, and schedules an empty block to slot 4 for forwarding. Wherein, an empty block means that the 66bit data of the block are all 0. For this case, the data sent by the FlexE interface to the link is: block5| empty block | block6| empty block.

Therefore, if the Eth interface and the FlexE interface interact, the Eth interface sends a message to the FlexE interface, and since the Eth interface sends data bit by bit and the FlexE receives data according to a specific number of slots (according to user configuration), the FlexE shim cannot resolve correct data. Correspondingly, the FlexE interface sends the message to the Eth interface, and the Eth interface cannot analyze correct data.

As can be seen from the above description of fig. 1a and 1b, if the physical interface supports being configured in the FlexE mode, the physical interface may be configured in both the Eth mode and the FlexE mode. When the physical interface is configured in Eth mode, FlexE shim of the physical interface does not do any processing on data. Whether the Flexe shim of the physical interface processes the data can be determined by the chip working mode of the physical interface. In one example, when the chip operating mode of the physical interface is configured as the Eth mode, the FlexE shim of the physical interface does not perform any processing on data, and at this time, the physical interface is an Eth interface; when the chip operating mode of the physical interface is configured to the FlexE mode, the FlexE shim of the physical interface is used to process data, for which case the physical interface actually operates in the FlexE mode, i.e. the physical interface is a FlexE interface.

It should be noted that, the aforementioned "physical interface support is configured in the FlexE mode", which means that the port configuration mode of the physical port can be configured in the FlexE mode. In other words, when configuring a physical port, in addition to configuring the chip operation mode of the physical interface, it is also necessary to configure the port configuration mode of the physical interface. Generally, the port configuration mode and the chip operation mode are consistent for one physical interface. For example, if the port configuration mode is the FlexE mode, the chip operating mode is also the FlexE mode; in another example, if the port configuration mode is an Eth mode, the chip operating mode is also the Eth mode. In one example, if the control management entity sends a configuration instruction 1 to the communication device, instructing the communication device to configure the physical port 1 in the FlexE mode, the communication device may configure both the port configuration mode and the chip operation mode of the physical port 1 in the FlexE mode based on the configuration instruction 1. In another example, if the control management entity issues a configuration instruction 2 to the communication apparatus, which instructs the communication apparatus to configure the physical port 1 as the Eth mode, the communication apparatus may configure both the port configuration mode and the chip operating mode of the physical port 1 as the Eth mode based on the configuration instruction 2.

The control management entity mentioned in the embodiment of the present application may be, for example, a device running a Network Management System (NMS), or may be a controller. The control management entity may be a functional module for implementing a control and/or management function, or may be a physical entity running a related functional module, for example, a server installed with related software for implementing the function of the control management entity. The embodiments of the present application are not particularly limited.

Unless otherwise specified, the port mentioned in the embodiments of the present application refers to a physical port of a communication device.

Next, possible application scenarios of the present application are introduced.

Referring to fig. 2a, the figure is a schematic diagram of an exemplary application scenario provided in the embodiment of the present application.

As shown in fig. 2a, the control management entity is connected to a communication device a, the communication device a is connected to a communication device B, and the communication device a communicates with a port B of the communication device 2 through a port a. Both port a and port b operate in Eth mode. Namely: the port configuration mode and the chip working mode of the port a are both Eth modes; the port configuration mode and the chip working mode of the port b are both Eth modes. At this time, the control management entity may manage the communication apparatus a and manage the communication apparatus B through the communication apparatus a (the instruction issued by the control management entity to the communication apparatus B is forwarded by the communication apparatus a).

If it is necessary to switch both the port a and the port B from the Eth mode to the FlexE mode, the switching times of the port a and the port B may not be strictly consistent, so that a phenomenon that normal communication cannot be performed between the communication apparatus a and the communication apparatus B may occur. In one example: when the port a is first switched to the FlexE mode, both the port a configuration mode and the chip operation mode are changed to the FlexE mode, and at this time, the port B still operates in the Eth mode, so that communication between the communication device a and the communication device B cannot be performed normally. Further, the control management entity cannot manage the communication device B any more (referred to as communication device B offline), because the command issued by the control management entity to the communication device B cannot be forwarded to the communication device B through the communication device a.

Referring to fig. 2b, the figure is a schematic diagram of an exemplary application scenario provided in the embodiment of the present application.

As shown in fig. 2B, the control management entity is connected to a communication device a, the communication device a is connected to a communication device B, and the communication device a communicates with a port B of the communication device 2 through a port a. Both port a and port b operate in Eth mode. Namely: the port configuration mode and the chip working mode of the port a are both Eth modes; the port configuration mode and the chip working mode of the port b are both Eth modes. At this time, the control management entity may manage the communication device a, and manage the communication device B through the communication device a.

If a communication device C is inserted between the communication device a and the communication device B, wherein the port C of the communication device C is used for communicating with the port a, the port d of the communication device C is used for communicating with the port B, and the port C and the port d both work in the FlexE mode. Namely: the port configuration mode and the chip working mode of the port c are both Flexe modes, and the port configuration mode and the chip working mode of the port d are both Flexe modes. At this time, since the port a operates in Eth mode and the port C operates in FlexE mode, normal communication between the communication device a and the communication device C is not possible, so that the communication device C and the communication device B are out of control. Further, since the port B operates in Eth mode and the port d operates in FlexE mode, normal communication between the communication device B and the communication device C is not possible.

Referring to fig. 2c, the figure is a schematic diagram of an exemplary application scenario provided in the embodiment of the present application.

As shown in fig. 2c, the control management entity is connected to the communication device a, the communication device a is connected to the communication device B, and the communication device a communicates with the port B of the communication device 2 through the port a. Both port a and port b operate in FlexE mode. Namely: the port configuration mode and the chip working mode of the port a are both Flexe modes; the port configuration mode and the chip working mode of the port b are both Flexe modes. At this time, the control management entity may manage the communication apparatus a, and manage the communication apparatus B through the communication apparatus a.

If a communication device C is inserted between the communication device a and the communication device B, wherein the port C of the communication device C is used for communicating with the port a, the port d of the communication device C is used for communicating with the port B, and both the port C and the port d work in the Eth mode. Namely: the port configuration mode and the chip working mode of the port c are both Eth modes, and the port configuration mode and the chip working mode of the port d are both Eth modes. At this time, since the port a operates in the FlexE mode and the port C operates in the Eth mode, normal communication between the communication device a and the communication device C is not possible, so that the communication device C and the communication device B are out of control. Further, since the port d operates in Eth mode and the port B operates in FlexE mode, normal communication between the communication device B and the communication device C is not possible.

As can be seen from the above description of fig. 2a, 2b and 2c, in the above scenario, two communication devices cannot normally communicate, and further, some communication devices may be out of control.

In view of this, the embodiments of the present application provide an interface configuration method, which can efficiently configure ports, so that normal communication between communication devices can be performed.

Next, a brief description is given of an interface configuration method provided in an embodiment of the present application with reference to the drawings.

Referring to fig. 3, this figure is a signaling interaction diagram of an interface configuration method provided in the embodiment of the present application. Fig. 3 shows an interface configuration method 100, wherein the communication device 1 in the method 100 includes a port 1, the communication device 2 in the method 100 includes a port 2, and the port 1 is used for communicating with the port 2. The method 100 may include, for example, S101-S106 as follows.

S101: the communication apparatus 1 determines that the chip operation mode of the port 2 is Eth mode.

In one example, before executing S101, both the port configuration mode and the chip operation mode of port 1 are FlexE modes.

In some embodiments, if FlexE communication is established between the communication apparatus 1 and the communication apparatus 2, the communication apparatus 1 may receive a FlexE overhead frame from the communication apparatus 2. Therefore, in one implementation, if the communication apparatus 1 does not receive the FlexE overhead frame sent by the communication apparatus 2 within the preset time, the communication apparatus 1 may determine that the chip operation mode of the port 2 is the Eth mode. Regarding the FlexE overhead frame, reference may be made to section 7.3.1 of the Optical Interconnection Forum (OIF) Flex ethernet2.0 standard, which is not described in detail herein.

S102: the communication apparatus 1 switches the chip operation mode of the port 1 to the Eth mode.

Since the chip operation mode of the port 1 is the FlexE mode, and the chip operation mode of the port 2 is the Eth mode, the port 1 and the port 2 cannot normally communicate, that is, the communication apparatus 1 and the communication apparatus 2 cannot normally communicate with each other. In order to enable normal communication between the communication device 1 and the communication device 2, in the embodiment of the present application, the communication device 1 may switch the chip operation mode of the port 1 to the Eth mode. In this way, the chip operation mode of the port 1 and the chip operation mode of the port 2 are both Eth modes, and thus normal communication between the communication device 1 and the communication device 2 is possible.

S103: the communication device 2 receives a configuration instruction 1 sent by the control management entity, and the configuration instruction 1 is used for instructing the communication device 2 to configure the port 2 into the FlexE mode.

In one example, both the port configuration mode and the chip configuration mode of port 2 are Eth mode before executing S103.

In this embodiment, if the communication device 2 is directly connected to the control management entity, the control management entity may directly issue the configuration instruction 1 to the communication device 2. If the communication device 1 is further included between the communication device 2 and the control management entity, the communication device 1 and the communication device 2 can communicate after S102 is executed, and therefore, the control management entity can issue the configuration instruction 1 to the communication device 2 through the communication device 1.

S104: the communication device 2 transmits instruction information 1 to the communication device 1, and the instruction information 1 instructs the communication device 1 to configure the chip operation mode of the port 1 to the FlexE mode.

S105: the communication device 2 configures both the port configuration mode and the chip operation mode of the port 2 to the FlexE mode.

After the communication device 2 receives the configuration instruction 1, in order to enable normal communication between the communication device 1 and the communication device 2 after the port 2 is configured based on the configuration instruction 1, the communication device 2 may send instruction information 1 to the communication device 1 before the port 2 is configured based on the configuration instruction 1, where the instruction information 1 is used for instructing the communication device 1 to configure the chip operation mode of the port 1 to the FlexE mode.

With respect to S105, it should be noted that, in one implementation, the communication apparatus 2 may configure the port configuration mode of the port 2 to the FlexE mode immediately after receiving the configuration instruction 1, then send the instruction information 1 to the communication apparatus 1, and configure the chip operation mode of the port 2 to the FlexE mode after sending the instruction information 1 to the communication apparatus 1. In still another implementation, after the communication apparatus 2 transmits the indication information 1 to the communication apparatus 1, the port configuration mode and the chip operation mode of the port 2 may be configured to be the FlexE mode.

The indication information 1 is not specifically limited in the embodiments of the present application, and in an example, the indication information 1 may be a Remote Fault (RF) indication. The RF indication is a PCS layer RF interrupt signal in the IEEE802.3 Eth standard, and reference may be made to the relevant description of the IEEE802.3 Eth standard for the RF indication, which is not described in detail herein.

In yet another example, the indication information 1 may be O in the ethernet frame 1₀Code blocks. When received O₀When the code block value is 0X00, the chip working mode of the sending port is Eth mode, and when the received O is in the Eth mode₀When the code block value is 0X05, the chip operation mode of the transmission port is the FlexE mode. With respect to O₀For the description of the code block, reference may be made to the description part of IEEE802.3-2015, section 82.2.3.3, which is not described in detail here. In the embodiment of the present application, if the indication information 1 is O in the ethernet frame 1₀Code block of O₀The code block may have a value of 0X 05.

In yet another example, the aforementioned indication information 1 may be carried in an ethernet frame 1 that the communication apparatus 2 transmits to the communication apparatus 1. The ethernet frame 1 may include an extended Type Length Value (TLV) field, and the extended TLV field is used to carry the indication information 1. In one implementation, a new type of ethernet frame may be defined, which is used to carry indication information 1. Referring to fig. 4, fig. 4 is a schematic structural diagram of an ethernet frame 1 according to an embodiment of the present disclosure.

As shown in fig. 4, the ethernet frame 1 includes a destination address field, a source address field, a type field, a chip mode switch notification field, and a Frame Check Sequence (FCS) field. Regarding the destination address field, the source address field, and the type field, reference may be made to the definition of the Eth frame in section 3.1.1 of IEEE802.3-2015, which is not described in detail herein. In this embodiment of the present application, the chip working mode switching notification field may be an extended TLV field, where the extended TLV field is used to carry the indication information 1. In one example, as shown in fig. 4, the chip operation mode switching notification field may include a message version (message version) field, a message type (message type) field, a message length (message length) field, and a message tlv (message tlv) field. The message TLV field may include a TLV type (type) field, a TLV length (length) field, and a TLV value (value) field.

For the ethernet frame 1 shown in fig. 4, the indication information 1 may be carried by the message type field, or may be carried by both the message type field and the message TLV field, which is not specifically limited in this embodiment of the application.

Regarding the ethernet frame 1 shown in fig. 1, in an example, the value of the type field may be 0x9100, the value of the message version field may be 0, the value of the message type may be 1, the value of the message length may be the length of the ethernet frame 1, the value of the TLV type field may be 1, and the content of the TLV length field is the length of the character string "HUAWEI ETH SWITCH FLEXE" carried by the character string "HUAWEI ETH SWITCH FLEXE".

In one implementation of the embodiment of the present application, in order to ensure that the communication apparatus 1 can receive the indication information 1, the communication apparatus 2 may periodically transmit the indication information 1 to the communication apparatus 1 within a predetermined time period. Taking the indication information 1 as an RF indication as an example, in the embodiment of the present application, the communication device 2 may periodically transmit the RF indication to the communication device 1 within 20 milliseconds, for example. The present embodiment does not specifically limit the predetermined time period, which may be continued for less than 1 second, for example, because the communication apparatus 1 may trigger an alarm if the communication apparatus 1 receives the RF indication for more than 1 second.

S106: the communication device 1 configures the chip operation mode of the port 1 to the FlexE mode based on the instruction information 1.

In one example, after the communication apparatus 1 receives the indication information 1, the chip operation mode of the port 1 may be configured to the FlexE mode based on the indication information 1. In this way, the port configuration mode and the chip operation mode of the port 1 are both FlexE modes, and the port configuration mode and the chip operation mode of the port 2 are both FlexE modes, so that FlexE communication can be normally performed between the port 1 and the port 2.

In an implementation manner of the embodiment of the present application, after executing S106, the communication device 1 may further periodically detect a chip operating mode of the port 2, and configure the chip operating mode of the port 1 when the chip operating mode of the port 2 is different from the chip operating mode of the port 1, so that the chip operating mode of the port 1 is consistent with the chip operating mode of the port 2.

As an example: after S106 is executed, the chip operating mode of the port 1 is the FlexE mode, and if the communication apparatus 1 determines that the chip operating mode of the port 2 is the Eth mode, the communication apparatus 1 may configure the chip operating mode of the port 1 as the Eth mode, so that the chip operating mode of the port 1 is the same as the chip operating mode of the port 2, and communication between the port 1 and the port 2 is possible. For a specific implementation that the communication apparatus 1 determines that the chip operating mode of the port 2 is the Eth mode, reference may be made to the above related description part of S101, which is not described in detail here.

As yet another example: after the communication device 1 may configure the chip operating mode of the port 1 to the Eth mode, if the communication device 1 determines that the chip operating mode of the port 2 is the FlexE mode, the communication device 1 may configure the chip operating mode of the port 1 to the FlexE mode, so that the chip operating mode of the port 1 is the same as the chip operating mode of the port 2, and thus, communication may be performed between the port 1 and the port 2.

In the embodiment of the present application, when the communication device 1 determines that the chip operating mode of the port 2 is the FlexE mode, there may be a plurality of implementation manners, and several possible implementation manners are described below.

In one implementation: considering that the port 1 may receive a block lock (lock lock) signal from the port 2 if the chip operation mode of the port 2 is Eth mode, if the communication apparatus 1 does not receive the block lock signal transmitted by the communication apparatus 2 within a preset time period, it may be determined that the chip operation mode of the port 2 is FlexE mode. Regarding the block lock signal, reference may be made to the relevant description part of section 82.2.19.3 of IEEE802.3-2015, which is not described in detail herein.

In one implementation: considering that if the chip operation mode of the port 2 is the Eth mode, the port 1 may receive an alignment mark lock (alignment mark lock) signal from the port 2, and therefore, if the communication apparatus 1 does not receive the alignment mark lock signal transmitted by the communication apparatus 2 within a preset time period, the chip operation mode of the port 2 may be determined to be the FlexE mode. For the alignment marker lock signal, reference may be made to the relevant description of section 82.2.19.3 of IEEE802.3-2015, which is not described in detail herein.

In one implementation: the communication device 1 can be based on O transmitted by the communication device 2₀The value of the code block to determine the chip mode of operation of port 2. Wherein: when communication device 2 transmits₀When the code block has a value of 0X05, the communication apparatus 1 may determine that the chip operation mode of the port 2 is the FlexE mode; when communication device 2 transmits₀When the code block has a value of 0X00, the communication apparatus 1 can determine that the chip operation mode of the port 2 is Eth mode.

In one implementation: the communication device 1 may send an ethernet frame 2 to the communication device 2, where the ethernet frame 2 may include indication information 2, and the indication information 2 is used to determine whether the chip operating mode of the port 2 is the Eth mode. If the chip operation mode of the port 2 is Eth mode, the communication device 2 may send a response to the ethernet frame 2 to the communication device 1. If the chip operation mode of the port 2 is the FlexE mode, the communication device 2 cannot correctly analyze the ethernet frame 2, and therefore the communication device 2 does not transmit a response to the ethernet frame 2 to the communication device 1. Therefore, for this case, if the communication apparatus 1 does not receive the response to the ethernet frame 2 transmitted by the communication apparatus 2 after transmitting the ethernet frame 2 to the communication apparatus 2, the communication apparatus 1 may determine that the chip operation mode of the port 2 is the Eth mode.

Regarding the ethernet frame 2, it should be noted that, referring to fig. 4, a structure of the ethernet frame 2 may refer to fig. 4, and in an example, the indication information 2 may be carried by a message type field of the ethernet frame 2, or may be carried by both the message type field of the ethernet frame 2 and the message TLV field, which is not specifically limited in the embodiment of the present application.

For example, the indication information 2 may be carried by a message type field of the ethernet frame 2, and the value of the message type field of the ethernet frame 2 may be 2. For another example, the indication information 2 is carried by the message type field and the message TLV field of the ethernet frame 2, and in this case, the value of the message type field of the ethernet frame 2 may be 1, and the value of the TLV type field of the ethernet frame 2 may be 2. In addition, the TLV value field of the ethernet frame 2 may be further used to indicate that the chip operating mode of the port 1 is an Eth mode, for example, which is not specifically limited in the embodiment of the present application.

In the embodiment of the present application, the response to the ethernet frame 2 sent by the communication apparatus 2 to the communication apparatus 1 may be, for example, an ethernet frame 3, where the ethernet frame 3 includes indication information 3, and the indication information 3 is used to indicate the response.

Regarding the ethernet frame 3, it should be noted that, with reference to fig. 4, the structure of the ethernet frame 3 may refer to fig. 4, and in an example, the indication information 3 may be carried by a message type field of the ethernet frame 3, or may be carried by both the message type field of the ethernet frame 3 and the message TLV field, which is not specifically limited in the embodiment of the present application.

For example, the indication information 3 may be carried by a message type field of the ethernet frame 3, and the value of the message type field of the ethernet frame 3 may be 3. For another example, the indication information 3 is carried by the message type field of the ethernet frame 3 and the message TLV field, and in this case, the value of the message type field of the ethernet frame 3 may be 1, and the value of the TLV type field of the ethernet frame 3 may be 3. In addition, the TLV value field of the ethernet frame 3 may also be used to indicate that the chip operating mode of the port 2 is an Eth mode, for example, which is not specifically limited in the embodiment of the present application.

In one implementation manner of the embodiment of the present application, when the port configuration mode of the port 1 is the FlexE mode and the chip operation mode is the Eth mode, the communication apparatus 1 may send the instruction information 4 to the communication apparatus 2, where the instruction information 4 is used to instruct the communication apparatus 2 to configure the chip operation mode of the port 2 as the FlexE mode. After the communication device 2 receives the instruction information 4, if the chip operation mode of the port 2 is the FlexE mode, the communication device 2 may ignore the instruction information 4. If the chip operation mode of the port 2 is the FlexE mode, the communication device 2 may configure the chip operation mode of the port 2 to the FlexE mode based on the instruction information 4.

Accordingly, if the port configuration mode of the port 2 is the FlexE mode and the chip operation mode is the Eth mode, the communication apparatus 2 may transmit the instruction information 5 to the communication apparatus 1, where the instruction information 5 instructs the communication apparatus 1 to configure the chip operation mode of the port 1 to the FlexE mode. For this case, the communication apparatus 1 may configure the chip operation mode of the port 1 to the FlexE mode after receiving the instruction information 5. And the communication device 2 may configure the chip operation mode of the port 2 to the FlexE mode after receiving the indication information 4. In this way, FlexE communication can be performed between the communication device 1 and the communication device 2.

The method 100 is described above, and a specific implementation manner of applying some or all of the steps of the method 100 to the scenarios shown in fig. 2a, fig. 2b and fig. 2c is described next.

For the application scenario shown in FIG. 2 a:

first, the control management entity issues a configuration instruction a to the communication device a, the configuration instruction a being used to instruct the communication device a to configure the port a in the FlexE mode. And the communication device A configures the port configuration mode and the chip working mode of the port a into a Flexe mode based on the configuration instruction a. Then, the communication device a determines that the chip operating mode of the port b is the Eth mode, so that the communication device a configures the chip operating mode of the port a to the Eth mode. The control management entity issues a configuration instruction B to the communication device B through the communication device A, wherein the configuration instruction B is used for instructing the communication device B to configure the port B into a Flexe mode. After receiving the configuration instruction B, the communication device B transmits instruction information 1 to the communication device a, wherein the instruction information 1 is used for instructing the communication device a to configure the chip operation mode of the port a into the FlexE mode. After receiving the instruction information 1, the communication device a switches the chip operation mode of the port a to the FlexE mode. The communication device B configures the port configuration mode of the port B to the FlexE mode after receiving the configuration instruction B, and configures the chip operation mode of the port B to the FlexE mode after transmitting the instruction information 1 to the communication device a. Thus, the port a and the port B realize switching from the Eth mode to the FlexE mode, and FlexE communication is possible between the communication device a and the communication device B, and the communication device B is not disconnected.

For the application scenario shown in FIG. 2 b:

first, the communication device C determines that the chip operation mode of the port a is the Eth mode, and thus the communication device C configures the chip operation mode of the port C to the Eth mode. The communication device C determines that the chip operation mode of the port b is the Eth mode, and thus the communication device C configures the chip operation mode of the port d to the Eth mode. Then, the control management entity issues a configuration instruction C to the communication device C through the communication device a, where the configuration instruction C is used to instruct the communication device C to configure the port C and the port d as an Eth mode. After receiving the configuration instruction C, the communication device C configures the port configuration modes of the port C and the port d into the Eth mode. Thus, the port C and the port d realize switching from the FlexE mode to the Eth mode, and the communication apparatus a and the communication apparatus C can perform Eth communication, the communication apparatus B and the communication apparatus C can perform Eth communication, and the communication apparatus B and the communication apparatus C do not become disconnected.

For the application scenario shown in fig. 2 c:

the communication device a determines that the chip operating mode of the port c is the Eth mode, so the communication device a configures the chip operating mode of the port a to the Eth mode. And the control management entity issues a configuration instruction d to the communication device C through the communication device A, wherein the configuration instruction d is used for instructing the communication device C to configure the port C and the port d into a Flexe mode. After receiving the configuration instruction d, the communication device C transmits instruction information 1 to the communication device a, where the instruction information 1 instructs the communication device a to configure the chip operation mode of the port a to the FlexE mode. After receiving the instruction information 1, the communication device a switches the chip operation mode of the port a to the FlexE mode. The communication device C configures the port configuration mode of the port C to the FlexE mode after receiving the configuration instruction d, and configures the chip operation mode of the port C to the FlexE mode after transmitting the instruction information 1 to the communication device a. After receiving the configuration instruction d, the communication device C may further configure both the port configuration mode and the chip operation mode of the port d to be a FlexE mode. Thus, the port C and the port d realize switching from the Eth mode to the FlexE mode, and FlexE communication is possible between the communication device a and the communication device C, FlexE communication is also possible between the communication device B and the communication device C, and the communication device B and the communication device C are not disconnected.
