Description

Technical Field

[0001] This application relates to the field of wireless technology, and in particular to a parameter configuration method, apparatus, device, and storage medium. Background Technology

[0002] Currently, after deploying Traffic Engineering (TE) or policies in a network, Bidirectional Forwarding Detection (BFD) or Seamless Bidirectional Forwarding Detection (SBFD) is deployed to quickly detect the status of TE tunnels or policy paths. However, currently, the deployment of tunnels or policies is independent of the deployment of BFD or SBFD. That is, after configuring tunnels or policies through protocols such as Path Computation Element Communication Protocol (PCEP) or Border Gateway Protocol (BGP), BFD or SBFD still needs to be configured manually or through methods such as netconf, making the process quite complex.

[0126] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0127] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0128] It should be noted that the terms "first, second, third" used in the embodiments of this application are used to distinguish similar or different objects and do not represent a specific order of objects. It is understood that "first, second, third" can be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0129] In related technologies, after deploying TE (Tunneling Path) or policies in a network, BFD (Block Path Deployment) or SBFD (Simplified Path Deployment) is deployed to quickly detect the status of the TE tunnel or policy path. However, currently, the deployment of tunnels or policies is independent of the deployment of BFD or SBFD. That is, after configuring tunnels or policies via protocols such as PCEP or BGP, BFD or SBFD still needs to be configured manually or through methods such as netconf, and the BFD or SBFD needs to be associated with the tunnel or policy. Policies include, but are not limited to, segment routing (SR) policies and SRv6 policies.

[0130] In summary, in the relevant technologies, the configuration of tunnels or policies is independent of the configuration of BFD or SBFD, and the configuration methods and protocols used are also different. After configuring tunnels or policies, it is necessary to further configure BFD or SBFD and associate BFD / SBFD with tunnels or policies, which is a long process with many steps.

[0131] In view of this, embodiments of this application provide a parameter configuration method, which can be applied to a first communication device or a second communication device. The function implemented by the parameter configuration method can be achieved by a processor in the communication device calling program code, which can be stored in a computer storage medium. Therefore, the communication device includes at least a processor and a storage medium.

[0132] Figure 1 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, applied to a first communication device, such as... Figure 1 As shown, the method includes the following steps 101 to 102:

[0133] Step 101: Receive a second message sent by the second communication device; the second message is used to request the configuration of a path or policy, and to configure parameters for path connectivity detection.

[0134] In some embodiments, the second communication device may request the first communication device to configure a primary path and a backup path, and request the first communication device to configure parameters for detecting the status of the primary path and the backup path, such as BFD parameters or SBFD parameters.

[0135] Step 102: Send a first message to the second communication device; the first message carries first information and a first configuration parameter or a second configuration parameter.

[0136] The first information is used for the second communication device to configure a path or policy; the first configuration parameter is used for the second communication device to configure a first parameter while configuring a path or policy; the second configuration parameter is used for the second communication device to configure a second parameter while configuring a path or policy; the first parameter or the second parameter is used for the second communication device to perform path connectivity detection.

[0137] It is understood that new content can be defined in the first message; the newly defined content can carry the first configuration parameter or the second configuration parameter.

[0138] It is understandable that when configuring paths using the PCEP protocol, the PCEP protocol is extended so that the first communication device configures path connectivity detection parameters simultaneously when issuing paths to the second communication device. Similarly, when configuring policies such as segment routing policies (SRPs) using the BGP protocol, the BGP protocol is extended so that the first communication device configures path connectivity detection parameters simultaneously when issuing policies to the second communication device.

[0139] It is understandable that the PCEP protocol can consist of request messages, response messages, initialization messages (PCInit), update messages (PCUpd), and report messages (PCRpt). Each message consists of an object, and each object consists of a TLV. Thus, for stateless PCEP, when the first message is a PCEP response message and the second message is a PCEP request message, the response message in PCEP is extended by adding objects or adding TLVs to existing objects to complete the distribution of path connectivity detection parameters.

[0140] It is understandable that the BGP protocol can be composed of messages, messages can be composed of attributes, attributes can be composed of TLVs, and TLVs can be composed of sub-TLVs. Thus, by extending the messages in BGP, the path connectivity detection parameters can be sent by adding attributes or adding TLVs or sub-TLVs to existing attributes.

[0141] The following embodiments use the extension of the PCEP protocol as an example for detailed explanation. The provided technical solutions are only one feasible way to extend PCEP, and other extension methods are also within the scope of protection of this application. It is understood that the technical solutions provided in the embodiments of this application are also applicable to other protocols. Other tunnel and policy configuration protocols, such as the BGP protocol, can also adopt similar methods. By extending the protocol, the configuration of tunnels / policies and the configuration of BFD / SBFD can be completed simultaneously, thereby simplifying the entire process.

[0142] It should be noted that, in this embodiment of the application, by extending the tunnel or policy configuration protocol, BFD / SBFD can be directly configured when configuring tunnels or policies, which simplifies the process and reduces the number of configuration steps.

[0143] This application also provides a parameter configuration method. Figure 2 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, as shown below. Figure 2 As shown, the method includes the following steps 201 to 204:

[0144] Step 201: The first communication device sends a third message to the second communication device; the third message is used to indicate that the first communication device supports configuring the first parameter and the second parameter.

[0145] Understandably, by extending the third message to declare capabilities, the first communication device (such as a Path Computation Element (PCE), which in actual networking could be a router, SDN controller, or other network element or network management system) and the second communication device (such as a Path Computation Client (PCC), which in actual networking could be a router or other network element)) can inform each other whether they support configuring the first parameter (such as the BFD parameter) and the second parameter (such as the SBFD parameter) when establishing a session.

[0146] Understandably, the way to expand the third message could be:

[0147] A new field is defined in a specific part of the third message; the newly defined field carries two flag bits; the two flag bits are used to indicate that the first communication device supports the configuration of the first parameter and the second parameter.

[0148] It is understandable that when extending the PCEP protocol, new fields can be defined in specific objects of a third message; these newly defined fields will carry two flag bits. Similarly, when extending the BGP protocol, new fields can be defined in specific attributes of a third message; these newly defined fields will carry two flag bits.

[0149] As a possible extension, the third message is a PCEP open message, in which two new flag bits are defined in the STATEFUL-PCE-CAPABILITY TLV field of the open object of the PCEP open message; the two flag bits are respectively used to indicate that the first communication device supports the configuration of the first parameter and the second parameter.

[0150] like Figure 3 As shown, two new flag bits are defined in the STATEFUL-PCE-CAPABILITY TLV field of the open object in the open message, namely the B flag bit and the S flag bit. The B flag bit being set indicates that the first communication device supports the configuration of BFD parameters, and the S flag bit being set indicates that the first communication device supports the configuration of SBFD parameters.

[0151] As another feasible extension method, the third message is an open message, in which a new TLV field is defined in the open object of the open message; two new flag bits are defined in the newly defined TLV field; the two flag bits are respectively used to indicate that the first communication device supports the configuration of the first parameter and the second parameter.

[0152] like Figure 4As shown, a new TLV field is defined in the open object of the open message. The specific value of Type in the TLV field is assigned by the international standards organization, and the length is 4. Flags defines B flag bits and S flag bits, and other bits are reserved. Setting the B flag bit indicates that the first communication device supports the configuration of BFD parameters, and setting the S flag bit indicates that the first communication device supports the configuration of SBFD parameters.

[0153] Step 202: The first communication device receives a second message sent by the second communication device; the second message is used to request the configuration of a path or policy, and to configure parameters for path connectivity detection.

[0154] Understandably, by extending the third message, the second communication device and the first communication device can inform each other whether they support configuring the first and second parameters when establishing a session. If both parties support configuring the first and second parameters, a session is established between the second communication device and the first communication device, and the first communication device receives the second message sent by the second communication device.

[0155] Step 203: The first communication device sends a first message to the second communication device; the first message carries first information and a first configuration parameter or a second configuration parameter.

[0156] This application also provides a parameter configuration method. Figure 5 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application. Taking the first configuration parameter as the BFD configuration parameter as an example, as follows... Figure 5 As shown, the method includes the following steps 501 to 502:

[0157] Step 501: Define a new first field in the specific object of the first message; carry the first configuration parameter in the newly defined first field.

[0158] One feasible way to carry BFD configuration parameters is as follows: the first message is a PCEP response message (PCRep, PathComputation Reply); a new BFD TLV field is defined in the RP object of the PCEP response message; the BFD configuration parameters are carried in the newly defined BFD TLV field. For example... Figure 6 As shown, type indicates that the newly defined TLV field is a BFD TLV, and the specific value is assigned by the international standards organization; Length indicates that the length of the newly defined TLV field is 24 bytes, excluding the length of the type and length fields; the definitions and meanings of other fields are the same as in RFC5880.

[0159] It is understandable that the RP object in the PCEP response message can carry not only the newly defined BFD TLV field, but also the newly defined B flag. When the B flag is set, it indicates that the configuration of BFD parameters is supported.

[0160] Step 502: Send the first message to the second communication device.

[0161] Understandably, by defining a new TLV field for the RP object of the PCEP response message, the PCEP response message can be extended, thereby enabling the configuration of BFD parameters for path connectivity detection while configuring the path or policy.

[0162] It should be noted that, in this embodiment of the application, the PCEP response message is extended by carrying the defined BFDTLV into the PCEP response message, so as to instruct the second communication device (such as PCC) to configure BFD at the same time when configuring the path.

[0163] Understandably, taking a PCEP request message as the second message and a PCEP response message as the first message, when the first communication device (e.g., PCE) receives a PCEP request message from a second communication device (e.g., PCC) containing an RP object with S and / or B bits, the PCEP response message must contain BFD / SBFD configuration parameters, regardless of whether the PCEP request message contains BFD / SBFD configuration parameters. The BFD / SBFD configuration parameters in the PCEP response message can be the same as those in the PCEP request message, or they can be set by the first communication device (e.g., PCE) according to a configuration strategy and thus differ from those in the PCEP request message. After receiving the PCEP response message containing BFD / SBFD configuration parameters, the second communication device (e.g., PCC) configures a BFD / SBFD session for the corresponding path in the PCEP response message according to the BFD / SBFD configuration parameters to detect the connectivity of the path.

[0164] Understandably, the first message can also be a message in the BGP protocol, by defining a new first field in a specific attribute of the BGP message; the newly defined first field carries BFD configuration parameters.

[0165] This application also provides a parameter configuration method. Figure 7 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application. Taking the first configuration parameter as the BFD configuration parameter as an example, as follows... Figure 7 As shown, the method includes the following steps 701 to 702:

[0166] Step 701: Define a new first object in the first message; carry the first configuration parameter in the newly defined first object.

[0167] Another feasible way to carry BFD configuration parameters is as follows: the first message is a PCEP response message; a new BFD object is defined in the PCEP response message; and the BFD configuration parameters are carried in the newly defined BFD object. For example... Figure 8 As shown, the BFD object header (header, Figure 8 The definition of the first 4 bytes (of the object) follows the specifications and format of RFC5440; the specific values ​​of object-class and OT are assigned by international standards organizations, indicating that this is a BFD object; the BFD object body (body, Figure 8 The definition of the last 24 bytes in the middle is as follows: Figure 8 The definition and meaning of its fields are the same as those in RFC5880.

[0168] Understandably, in addition to carrying the newly defined BFD object, the PCEP response message can also carry an RP object containing the newly defined B flag, which is set to indicate that configuration of BFD parameters is supported.

[0169] Step 702: Send the first message to the second communication device.

[0170] Understandably, by defining a new BFD object for the PCEP response message, the PCEP response message can be extended, thereby enabling the configuration of BFD parameters for path connectivity detection while configuring the path or policy.

[0171] It should be noted that, in this embodiment of the application, the PCEP response message is extended by carrying the defined BFD object into the PCEP response message, so as to instruct the second communication device (such as PCC) to configure BFD at the same time when configuring the path.

[0172] Understandably, the first message can also be a message in the BGP protocol, by defining a new first attribute in the BGP message; and carrying BFD configuration parameters in the newly defined first attribute.

[0173] This application also provides a parameter configuration method. Figure 9 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application. Taking the second configuration parameter as the SBFD configuration parameter as an example, as follows... Figure 9 As shown, the method includes the following steps 901 to 902:

[0174] Step 901: Define a new second field in the specific object of the first message; carry the second configuration parameter in the newly defined second field.

[0175] One feasible way to carry SBFD configuration parameters is as follows: the first message is a PCEP response message; a new SBFD TLV field is defined in the RP object of the PCEP response message; the SBFD configuration parameters are carried in the newly defined SBFD TLV field. For example... Figure 10 As shown, type indicates that the newly defined TLV field is an SBFD TLV, and the specific value is assigned by the international standards organization; Length indicates that the length of the newly defined TLV field is 24 bytes, excluding the length of the type and length fields; the definitions and meanings of other fields are the same as in RFC5880.

[0176] Understandably, in addition to carrying the newly defined SBFD TLV field, the RP object in the PCEP response message can also carry the newly defined B flag. When the B flag is set, it indicates that the SBFD parameters can be configured.

[0177] Step 902: Send the first message to the second communication device.

[0178] Understandably, by defining a new TLV field in the RP object of the PCEP response message, the PCEP response message can be extended, thereby enabling the configuration of SBFD parameters for path connectivity detection while configuring the path or policy.

[0179] It should be noted that, in this embodiment of the application, the PCEP response message is extended by carrying the defined SBFD TLV into the PCEP response message, so as to instruct the second communication device (such as PCC) to configure SBFD at the same time when configuring the path.

[0180] Understandably, the first message can also be a message in the BGP protocol, by defining a new second field in a specific attribute of the BGP message; the newly defined second field carries SBFD configuration parameters.

[0181] This application also provides a parameter configuration method. Figure 11 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application. Taking the second configuration parameter as the SBFD configuration parameter as an example, as follows... Figure 11 As shown, the method includes the following steps 1101 to 1102:

[0182] Step 1101: Define a new second object in the first message; carry the second configuration parameter in the newly defined second object.

[0183] Another feasible way to carry SBFD configuration parameters is as follows: the first message is a PCEP response message; a new SBFD object is defined in the PCEP response message; the SBFD configuration parameters are carried in the newly defined SBFD object. For example... Figure 12 As shown, the SBFD object header (header, Figure 12 The definition of the first 4 bytes (in the code) follows the specifications and format of RFC5440; the specific values ​​of object-class and OT are assigned by international standards organizations, indicating that this is an SBFD object; the SBFD object body (body, Figure 12 The definition of the last 24 bytes in the middle is as follows: Figure 12 The definition and meaning of its fields are the same as those in RFC5880.

[0184] Understandably, in addition to carrying the newly defined SBFD object, the PCEP response message can also carry the newly defined B flag, which is set to indicate that SBFD parameters can be configured.

[0185] Step 1102: Send the first message to the second communication device.

[0186] Understandably, by defining a new SBFD object for the PCEP response message, the PCEP response message can be extended, thereby enabling the configuration of SBFD parameters for path connectivity detection while configuring the path or policy.

[0187] It should be noted that, in this embodiment of the application, the PCEP response message is extended by carrying the defined SBFD object into the PCEP response message, so as to instruct the second communication device (such as PCC) to configure SBFD at the same time when configuring the path.

[0188] Understandably, the first message can also be a message in the BGP protocol, by defining a new second attribute in the BGP message; the newly defined second attribute carries SBFD configuration parameters.

[0189] Figure 13 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, applied to a second communication device, such as... Figure 13 As shown, the method includes the following steps 1301 to 1302:

[0190] Step 1301: Send a second message to the first communication device; the second message is used to request the configuration of a path or policy, and the parameters for configuring path connectivity detection.

[0191] In some embodiments, the second communication device may request the first communication device to configure a primary path and a backup path, and request the first communication device to configure parameters for detecting the status of the primary path and the backup path, such as BFD parameters or SBFD parameters.

[0192] Step 1302: Receive a first message sent by the first communication device; the first message carries first information and a first configuration parameter or a second configuration parameter.

[0193] The first information is used for the second communication device to configure a path or policy; the first configuration parameter is used for the second communication device to configure a first parameter while configuring a path or policy; the second configuration parameter is used for the second communication device to configure a second parameter while configuring a path or policy; the first parameter or the second parameter is used for the second communication device to perform path connectivity detection.

[0194] It is understandable that new content can be defined in the second message; the newly defined content can be used to request the configuration path or strategy, as well as the parameters for configuring path connectivity detection.

[0195] It is understandable that when using the PCEP protocol, the second message in PCEP is extended by adding new flags to existing objects to request the configuration of paths or policies, as well as the parameters for configuring path connectivity detection.

[0196] Understandably, when using the BGP protocol, the second message in BGP is extended by adding new flags to existing attributes to request the configuration of paths or policies, as well as parameters for configuring path connectivity detection.

[0197] As described above, by extending the third message, the first communication device and the second communication device can inform each other whether they support configuring the first parameter and the second parameter when establishing a session. If both parties support configuring the first parameter and the second parameter, a session is established between the second communication device and the first communication device, and the second communication device then sends a second message to the first communication device.

[0198] This application also provides a parameter configuration method. Figure 14 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, as shown below. Figure 14 As shown, the method includes the following steps 1401 to 1402:

[0199] Step 1401: Define two new flag bits in the specific object of the second message; the two flag bits are used to request the configuration of the first parameter and the second parameter, respectively.

[0200] One feasible way to extend the PECP request message is as follows: the second message is a PCEP request message; a first flag and a second flag are newly defined in the RP object of the PCEP request message; the first flag is used to request the configuration of the first parameter; the second flag is used to request the configuration of the second parameter. For example... Figure 15 As shown, two new flags are defined to represent requests for configuring BFD and SBFD, respectively. The B flag indicates a request to configure BFD parameters, and the S flag indicates a request to configure SBFD parameters.

[0201] Optionally, when requesting BFD / SBFD configuration, relevant parameters can also be carried. The methods for carrying BFD or SBFD parameters have been described above and will not be repeated here.

[0202] Step 1402: Send the second message to the first communication device; the second message is used to request the configuration of a path or policy, and to configure the parameters for path connectivity detection.

[0203] Figure 16 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, applied to a first communication device, such as... Figure 16 As shown, the method includes the following steps 1601 to 1602:

[0204] Step 1601: Send a fourth message to the second communication device; the fourth message carries first information and first configuration parameters or second configuration parameters.

[0205] The first information is used for the second communication device to configure a path or policy; the first configuration parameter is used for the second communication device to configure a first parameter while configuring a path or policy; the second configuration parameter is used for the second communication device to configure a second parameter while configuring a path or policy; the first parameter or the second parameter is used for the second communication device to perform path connectivity detection.

[0206] It is understood that new content can be defined in the fourth message; the newly defined content carries the first configuration parameter or the second configuration parameter.

[0207] It is understandable that, for stateful PCE, when the fourth message is a PCEP initialization message, the initialization message in the PCEP is extended, and the path connectivity detection parameters are sent by adding objects or adding TLVs to existing objects.

[0208] It is understandable that, for the BGP protocol, when the fourth message is a message in BGP, the message in BGP is extended by adding attributes or adding TLVs or sub-TLVs to existing attributes to complete the distribution of path connectivity detection parameters.

[0209] As described above, by extending the third message, the first communication device and the second communication device can inform each other whether they support configuring the first and second parameters when establishing a session. If both parties support configuring the first and second parameters, a session is established between the second communication device and the first communication device, and then the first communication device sends a fourth message to the second communication device.

[0210] The following section explains how to expand the fourth message in different cases.

[0211] In the first scenario, a third field is defined in a specific object of the fourth message; the first configuration parameter is carried in the newly defined third field.

[0212] The fourth message is the PCEP initialization message; a new BFD TLV field is defined in the SRP object of the PCEP initialization message; the newly defined BFD TLV field carries BFD configuration parameters. The definition of BFD TLV in the SRP object is the same as the definition of BFD TLV in the RP object described above. The value of type can be the same as the BFD TLV in the RP, or a new type value can be assigned to the BFD TLV in the SRP by the international standards organization.

[0213] In the second scenario, a third object is defined in the fourth message; the first configuration parameters are carried in the newly defined third object.

[0214] The fourth message is the PCEP initialization message; a new BFD object is defined in the PCEP initialization message; the newly defined BFD object carries BFD configuration parameters. The BFD object has been described above. Optionally, the international standards organization can assign a new type value (determined by the object-class and OT fields) to the BFD object in the PCEP initialization message, or the type value of the BFD object in the PCEP request message can be used.

[0215] In the third scenario, a new fourth field is defined in a specific object of the fourth message; the second configuration parameter is carried in the newly defined fourth field.

[0216] The fourth message is the PCEP initialization message; a new SBFDTLV field is defined in the SRP object of the PCEP initialization message; the newly defined SBFD TLV field carries SBFD configuration parameters. The definition of SBFD TLV in SRP is the same as that in RP. The value of type can be the same as that of SBFD TLV in RP, or a new type value can be assigned to the SBFD TLV in SRP by the international standards organization.

[0217] In the fourth scenario, a new fourth object is defined in the fourth message; the second configuration parameter is carried in the newly defined fourth object.

[0218] The fourth message is a PCEP initialization message; a new SBFD object is defined in the PCEP initialization message; the newly defined SBFD object carries SBFD configuration parameters. The SBFD object has been described above. Optionally, the international standards organization can assign a new type value (determined by the object-class and OT fields) to the SBFD object in the PCEP initialization message, or the type value of the SBFD object in the PCEP request message can be used.

[0219] It is understandable that, in addition to carrying the newly defined BFD TLV, BFD object, SBFDTLV, and SBFD object, the PCEP initialization message can also carry a B flag requesting BFD configuration, indicating a request to configure BFD parameters; or, it can also carry an S flag requesting SBFD configuration, indicating a request to configure SBFD parameters, such as... Figure 17 As shown.

[0220] It is understood that the fourth message can also be a message in the BGP protocol, by defining a new third field in a specific attribute of the BGP message and carrying BFD configuration parameters in the newly defined third field; or by defining a new third attribute in the BGP message and carrying BFD configuration parameters in the newly defined third attribute; or by defining a new fourth field in a specific attribute of the BGP message and carrying SBFD configuration parameters in the newly defined fourth field; or by defining a new fourth attribute in the BGP message and carrying SBFD configuration parameters in the newly defined fourth attribute.

[0221] Figure 18 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, applied to a first communication device, such as... Figure 18 As shown, the method includes the following steps 1801:

[0222] Step 1801: Send a fifth message to the second communication device; the fifth message instructs the second communication device to perform path or policy configuration updates, as well as configuration updates of the first parameter and the second parameter.

[0223] Understandably, after the first communication device (e.g., PCE) sends a fourth message (e.g., a PCEP initialization message) to the second communication device (e.g., PCC), the PCC, upon receiving the PCEP initialization message carrying BFD / SBFD configuration parameters, configures a BFD / SBFD session for the corresponding path in the PCEP initialization message according to the BFD / SBFD configuration parameters, for detecting the connectivity of the path. Then, if the PCC detects a path failure, the PCC can request the PCE to update the path or policy configuration, as well as the configuration of the path connectivity detection parameters.

[0224] It is understood that new content can be defined in the fifth message; the newly defined content carries the updated first configuration parameter or second configuration parameter.

[0225] It is understandable that, for stateful PCE, when the fifth message is a PCEP update message, the update message in PCEP is extended, and the updated path connectivity detection parameters are sent out by adding objects or adding TLVs to existing objects.

[0226] It is understandable that, for the BGP protocol, when the fifth message is a message in BGP, the message in BGP is extended by adding attributes or adding TLVs or sub-TLVs to existing attributes to complete the distribution of updated path connectivity detection parameters.

[0227] The following section explains how to expand the fifth message in different cases.

[0228] In the first scenario, a new fifth field is defined in a specific object of the fifth message; the updated first configuration parameter is carried in the newly defined fifth field.

[0229] The fifth message is a PCEP update message (PCUpd, Path Computation LSP Update Request message); a new BFD TLV field is defined in the SRP object of the PCEP update message; the updated BFD configuration parameters are carried in the newly defined BFD TLV field.

[0230] It is understandable that the SRP object in the PCEP update message can carry not only the newly defined BFD TLV field, but also the newly defined B flag. When the B flag is set, it indicates that the configuration of BFD parameters is supported.

[0231] In the second scenario, a new fifth object is defined in the fifth message; the newly defined fifth object carries the updated first configuration parameters.

[0232] The fifth message is a PCEP update message; a new BFD object is defined in the PCEP update message; the updated BFD configuration parameters are carried in the newly defined BFD object.

[0233] Understandably, in addition to carrying the newly defined BFD object, the PCEP update message can also carry the newly defined B flag, which is set to indicate that the BFD parameters can be configured.

[0234] In the third scenario, a sixth field is defined in a specific object of the fifth message; the second configuration parameter is carried in the newly defined sixth field.

[0235] The fifth message is a PCEP update message; a new SBFD TLV field is defined in the SRP object of the PCEP update message; the updated SBFD configuration parameters are carried in the newly defined SBFD TLV field.

[0236] Understandably, in addition to carrying the newly defined SBFD TLV field, the SRP object in the PCEP update message can also carry the newly defined S flag bit. When the S flag bit is set, it indicates that the SBFD parameters can be configured.

[0237] In the fourth scenario, a new sixth object is defined in the fifth message; the newly defined sixth object carries the updated second configuration parameters.

[0238] The fifth message is a PCEP update message; a new SBFD object is defined in the PCEP update message; the updated SBFD configuration parameters are carried in the newly defined SBFD object.

[0239] Understandably, in addition to carrying the newly defined SBFD object, the PCEP update message can also carry the newly defined S flag, which is set to indicate that the SBFD parameters can be configured.

[0240] Understandably, the way to extend the PCEP update message is to include the aforementioned extended SRP object, BFDTLV, SBFD TLV, BFD object, and SBFD object into the PCEP update message, so as to instruct the second communication device (such as PCC) to perform BFD / SBFD update configuration at the same time when performing path update configuration.

[0241] It is understood that the fifth message can also be a message in the BGP protocol, by defining a new fifth field in a specific attribute of the BGP message and carrying the updated BFD configuration parameters in the newly defined fifth field; or by defining a new fifth attribute in the BGP message and carrying the updated BFD configuration parameters in the newly defined fifth attribute; or by defining a new sixth field in a specific attribute of the BGP message and carrying the updated SBFD configuration parameters in the newly defined sixth field; or by defining a new sixth attribute in the BGP message and carrying the updated SBFD configuration parameters in the newly defined sixth attribute.

[0242] Figure 19 This is a schematic diagram illustrating the implementation flow of the parameter configuration method in an embodiment of this application, applied to a second communication device, such as... Figure 19 As shown, the method includes the following steps 1901:

[0243] Step 1901: Send a sixth message to the first communication device; the sixth message is used to notify the first communication device of the current path or policy configuration, its status, the current first configuration parameters and second configuration parameters, and the path connectivity status.

[0244] Understandably, if the second communication device detects a path failure, it can send a sixth message to the first communication device; after receiving the sixth message, the first communication device can send a fifth message to the second communication device to instruct the second communication device to update the path or policy configuration and the configuration of the path connectivity detection parameters.

[0245] It is understandable that new content is defined in the sixth message; the newly defined content carries the current first configuration parameter and path connectivity status, or the second configuration parameter and path connectivity status.

[0246] It is understandable that, for stateful PCE, when the sixth message is a PCEP report message, the report message in PCEP is extended by adding objects or adding TLVs to existing objects to notify the first communication device of the current path or policy configuration, its status, the current first configuration parameters and second configuration parameters, and the path connectivity status.

[0247] It is understandable that, for the BGP protocol, when the sixth message is a message in BGP, the message in BGP is extended by adding attributes or adding TLVs or sub-TLVs to existing attributes to notify the first communication device of the current path or policy configuration, its status, the current first configuration parameters and second configuration parameters, and the path connectivity status.

[0248] The following section explains how to expand the sixth message in different cases.

[0249] In the first case, a new seventh field is defined in a specific object of the sixth message; the newly defined seventh field carries the current first configuration parameter and the path connectivity status.

[0250] The sixth message is the PCEP report message (PCRpt, Path Computation LSP State Report message); a new BFD TLV field is defined in the SRP object of the PCEP report message; the newly defined BFD TLV field carries the current BFD configuration parameters and path connectivity status.

[0251] It is understandable that the SRP object in the PCEP report message can carry not only the newly defined BFD TLV field, but also the newly defined B flag. When the B flag is set, it indicates that the configuration of BFD parameters is supported.

[0252] In the second scenario, a new seventh object is defined in the sixth message; the newly defined seventh object carries the current first configuration parameters and the path connectivity status.

[0253] The sixth message is a PCEP report message; a new BFD object is defined in the PCEP report message; the newly defined BFD object carries the current BFD configuration parameters and path connectivity status.

[0254] Understandably, in addition to carrying the newly defined BFD object, the PCEP report message can also carry the newly defined B flag, which is set to indicate that the BFD parameters can be configured.

[0255] In the third scenario, a new eighth field is defined in a specific object of the sixth message; the newly defined eighth field carries the current second configuration parameter and the path connectivity status.

[0256] In some embodiments, the sixth message is a PCEP report message; a new SBFD TLV field is defined in the SRP object of the PCEP report message; the newly defined SBFD TLV field carries the current SBFD configuration parameters and path connectivity status.

[0257] It is understandable that the SRP object in the PCEP report message can carry not only the newly defined SBFD TLV field, but also the newly defined S flag. When the S flag is set, it indicates that the SBFD parameters can be configured.

[0258] In the fourth scenario, a new eighth object is defined in the sixth message; the newly defined eighth object carries the current second configuration parameters and the path connectivity status.

[0259] The sixth message is a PCEP report message; a new SBFD object is defined in the PCEP report message; the newly defined SBFD object carries the current SBFD configuration parameters and path connectivity status.

[0260] Understandably, in addition to carrying the newly defined SBFD object, the PCEP report message can also carry the newly defined S flag, which is set to indicate that SBFD parameters can be configured.

[0261] Understandably, the way to extend the PCEP report message is to include the aforementioned extended SRP object, BFDTLV, SBFD TLV, BFD object, and SBFD object into the PCEP report message to inform the first communication device (such as the PCE) of the BFD / SBFD parameters and status configured for the corresponding path. After receiving the PCEP report message carrying the BFD / SBFD configuration parameters and status, the PCE can modify the BFD / SBFD configuration parameters, or adjust or optimize the corresponding path, and then send the updated path and BFD / SBFD configuration information to the PCC through the aforementioned PCEP update message.

[0262] It should be noted that, in the various embodiments of this application, firstly, BFD / SBFD can be configured simultaneously for path connectivity detection when configuring TE or SR policy paths. Secondly, detailed extensions to the PCEP path configuration protocol are provided, including extensions to capability declarations, methods for carrying BFD parameters, and methods for carrying SBFD parameters. Other protocols such as BGP can also be extended using the same methods. Thirdly, for bidirectional tunnels and policies, by using the parameter configuration method proposed in this application to configure the path and BFD / SBFD parameters in one direction at the head and tail nodes of the tunnel and policy paths respectively, automatic configuration of BFD / SBFD for bidirectional tunnels and policy paths can be achieved, and the incoming and outgoing paths of BFD / SBFD can be made consistent with the incoming and outgoing paths of bidirectional tunnels / policies.

[0263] To implement the parameter configuration method of this application embodiment, this application embodiment also provides a parameter configuration device, which is disposed on a first communication device. Figure 20 This is a schematic diagram of the composition structure of the parameter configuration device in an embodiment of this application; as shown Figure 20 As shown, the device includes:

[0264] The first receiving unit 201 is used to receive a second message sent by the second communication device; the second message is used to request the configuration of a path or policy, and to configure parameters for path connectivity detection.

[0265] The first sending unit 202 is used to send a first message to the second communication device; the first message carries first information and a first configuration parameter or a second configuration parameter;

[0266] Wherein, the first information is used for the second communication device to configure a path or policy; the first configuration parameter is used for the second communication device to configure a first parameter while configuring a path or policy; the second configuration parameter is used for the second communication device to configure a second parameter while configuring a path or policy; the first parameter or the second parameter is used for the second communication device to perform path connectivity detection.

[0267] In one embodiment, the first transmitting unit 202 is specifically used for:

[0268] Define new content in the first message; carry the first configuration parameter or the second configuration parameter in the newly defined content; send the first message to the second communication device.

[0269] The step of defining new content in the first message, and carrying the first configuration parameter or the second configuration parameter in the newly defined content, includes:

[0270] Define a new first field in a specific attribute of the first message; carry the first configuration parameter in the newly defined first field;

[0271] or,

[0272] Define a second field in a specific attribute of the first message; carry the second configuration parameter in the newly defined second field;

[0273] or,

[0274] Define a new first attribute in the first message; carry the first configuration parameter in the newly defined first attribute;

[0275] or,

[0276] Define a new second attribute in the first message; carry the second configuration parameter in the newly defined second attribute.

[0277] The step of defining new content in the first message, and carrying the first configuration parameter or the second configuration parameter in the newly defined content, includes:

[0278] Define a new first field in a specific object of the first message; carry the first configuration parameter in the newly defined first field; send the first message to the second communication device;

[0279] or,

[0280] Define a new first object in the first message; carry the first configuration parameters in the newly defined first object; send the first message to the second communication device;

[0281] or,

[0282] Define a second field in a specific object of the first message; carry the second configuration parameter in the newly defined second field; send the first message to the second communication device;

[0283] or,

[0284] In the first message, a second object is defined; the second configuration parameter is carried in the newly defined second object; and the first message is sent to the second communication device.

[0285] In one embodiment, the first sending unit 202 is further configured to: send a third message to the second communication device before receiving the second message sent by the second communication device through the first receiving unit 201; the third message is used to indicate that the first communication device supports configuring the first parameter and the second parameter.

[0286] Specifically, a new field is defined in a specific object of the third message; the newly defined field carries two flag bits; the two flag bits are used to indicate that the first communication device supports the configuration of the first parameter and the second parameter.

[0287] In practical applications, the first receiving unit 201 and the first sending unit 202 can be implemented by the communication interface in the parameter configuration device.

[0288] It should be noted that the parameter configuration device provided in the above embodiments is only illustrated by the division of the above program modules. In actual applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program modules to complete all or part of the processing described above. In addition, the parameter configuration device and parameter configuration method embodiments provided in the above embodiments belong to the same concept, and their specific implementation process can be found in the method embodiments, which will not be repeated here.

[0289] To implement the parameter configuration method of this application embodiment, this application embodiment also provides a parameter configuration device, which is disposed on a second communication device. Figure 21This is a schematic diagram of the composition structure of the parameter configuration device in an embodiment of this application; as shown Figure 21 As shown, the device includes:
