Technical Field

The embodiment of the invention relates to the technical field of networks, in particular to a parameter configuration method, device and system.

Background

The network generally includes at least two network devices, and the at least two network devices are configured to forward service data of a service corresponding to an access terminal to the access terminal. For example, the network device is a switch, and the access terminal is a set-top box, the switch is configured to forward service data provided by the application server to the set-top box.

In the network 100 shown in fig. 1, the device types of the access terminal 151 include: a Wireless Access Point (WAP) or a wired access terminal. For example, the wired access terminal is a set-top box or a computer. When the access terminal 151 belongs to different device types, the service data that needs to be forwarded to the access terminal 151 is different, and the network device in the network 100 for forwarding the service data also needs different configurations when forwarding the service data. Therefore, the network administrator needs to configure the network device in advance according to the device type of the access device 151. For example, assume that the access terminal 151 is a WAP, which is controlled or managed by the wireless access point controller. The WAP establishes a connection with the wireless access point controller and joins a Virtual Local Area Network (VLAN), thereby providing a wireless network for wireless terminals such as mobile phones, tablet computers, and portable computers. As with network 100 shown in fig. 1, radio access point controller 160 is typically coupled to network device 110. In fig. 1, the network devices that forward traffic data for access terminal 151 are network device 110, network device 120, and network device 130. The network administrator configures network device 110, network device 120, and network device 130 based on the VLAN identification of the virtual local area network that the WAP needs to join. Network device 110 sends and/or receives traffic data identified by the VLAN through port 111. Network device 120 sends and/or receives traffic data identified by the VLAN through port 121 and port 122. Network device 130 sends and/or receives traffic data identified by the VLAN through port 131 and port 132.

For each access terminal, a network administrator needs to manually configure parameters of related network equipment in advance, and the parameter configuration process is complex and inefficient.

Referring to fig. 5, a flowchart of a parameter configuration method according to an exemplary embodiment of the present application is shown. This embodiment is exemplified by that the method is used in a parameter configuration system as shown in fig. 3, where at least two network devices include a management network device, a relay network device and an access network device, and the method includes the following steps:

step 501, an access network device determines access parameters of an access terminal.

The access terminal enables LLDP while the access terminal is connected to the access network device.

The access terminal adds the device type, the device address and the port identification of the access terminal into a type-length-value (TLV) triple in an LLDP data unit (LLDPDU) of an LLDP frame.

The access terminal sends an LLDP frame to the access network device. After receiving an LLDP frame sent by an access terminal, an access network device obtains a device type, a device address, and a port identifier of the access terminal.

The format of one TLV triplet is shown in fig. 6, where a type (type) field is used to indicate the type of data included in the TLV triplet, a length (length) field is used to indicate the length of the data included in the TLV triplet, i.e., the length occupied by a value (value) field, and the value field is used to indicate the content of the data included in the TLV triplet. The byte length occupied by the type field and the length field is usually fixed, the length occupied by the value field is variable, and optionally, both the type field and the length field occupy two bytes.

For the TLV triples included in the LLDP data unit, when the values of the type fields are different, the meaning of the information in the value fields is also different. The meaning of some TLVs in LLDP data units is shown in figure 7.

Wherein, when the type field is 0, the value field is used to indicate the end of the PDU, the value field occupies 1 byte, and the length is 1. When the value field is 1, the end of the PDU is indicated. When the type field is 1, the value field is used to indicate the device address of the access terminal, typically the MAC address of the access terminal, the value field occupies 6 bytes, and the length field is 6. When the type field is 2, the value field is used to indicate the port identification of the access terminal, usually a port name in the form of a string, the value field usually occupies 16 bytes, and the length field is 16. The value field is used to indicate the device type of the access terminal when the type field is 9, the value field typically occupies 1 byte, and the length field is 1. Optionally, when the value field is 1, the device type is WAP, and when the value field is 0, the device type is a wired access terminal.

In this embodiment, at least 3 TLV triplets related to the access parameter in one LLDP data unit are included, and are respectively used to indicate the device type, the device address, and the port identifier of the access terminal. In actual implementation, the LLDP data unit generally further includes a TLV triple used for indicating the validity period of the LLDP data unit, a TLV triple used for indicating the end of the LLDP data unit, and the LLDP data unit may further include other self-defined TLV triples, which is not described in this embodiment again.

For example, assuming that the network topology of each network device in the parameter configuration system shown in fig. 3 is as shown in fig. 8, a schematic diagram of TLV triplets included in the LLDP data unit received by the access network device 330 is as shown in fig. 9, and is used to indicate that the device address of the access terminal 351 is MAC1, the port name of the port 3511 used for connecting to the access network device 330 in the access terminal 351 is GE0/0/1, and the device type of the access terminal 351 is WAP.

After determining the device type of the access terminal, the access network device determines the access position of the access terminal in the access network device and the device address of the access terminal. Optionally, the access location determined by the access network device is a port identifier of a network port used for connecting to the access terminal in the access network device, and the port identifier is usually a port name in the form of a character string.

Step 502, the access network device sends access parameters to the management network device.

Optionally, the management network device may communicate with other network devices by using a CAPWAP protocol, and the access network device sends the access parameter to the management network device by using the CAPWAP protocol. The access network equipment sends a CAPWAP message to the management network equipment, and the CAPWAP message carries access parameters.

One format of a CAPWAP message sent by an access network device to a management network device is shown in fig. 10, where the CAPWAP message includes an Internet Protocol (IP) header, a User Datagram Protocol (UDP) header, a CAPWAP header, and an ethernet frame. The Ethernet frame comprises the message data in the CAPWAP message. Optionally, the ethernet frame is used to transmit message data such as version number, serial number, message type, and access parameter of the CAPWAP message.

Optionally, the access parameter includes at least one set of message type field and parameter field. Optionally, the access parameter is encapsulated in a TLV triple format, and a group of packet type field, parameter field, and packet length field is added to one TLV triple, where the type field in the TLV triple is the packet type field, the length field is the packet length field, and the value field is the parameter field.

Optionally, the ethernet frame is transmitted through the message format shown in fig. 11, and the meaning of each field is as follows:

1. a version number (version) field, which occupies a length of 1 byte, for indicating the version number used by the message, and is typically 0x 01.

2. A packet type field (packet type) occupying a length of 1 byte for indicating a packet type. The message type includes a request message and a response message, and in general, when the field is 0x01, the message type for indication is the request message, and when the field is 0x02, the message type for indication is the response message; in this embodiment, the CAPWAP message reported by the access network device to the management network device is a request message, and this field is 0x 01.

3. A sequence number (sequence) field occupying 1 byte length for indicating the sequence number of the message. The sequence number of the request message is sequentially increased by 1 from 0, and the sequence number of the response message is the same as the sequence number of the received request message; for example, the sequence number of the first request packet reported by the access network device to the management network device is 0, the sequence number of the second request packet reported is 1, the sequence number of the third request packet reported is 2, and so on.

4. The first reserved (reserved 1) field, occupies 1 byte.

5. The second reserved (reserved 2) field, takes 2 bytes.

The meaning of TLV triplets in ethernet frames is shown in fig. 12. When the message type field is the first type field, the parameter field of the same group is used for indicating the equipment address of the access network equipment. When the message type field is a second type field, the parameter field of the same group is used for indicating the device type of the access terminal and/or the access position of the access terminal in the access network device. In this embodiment, the parameters such as the device address and the port identifier of the access terminal indicated in the ethernet frame are not described in detail. In fig. 12, a type field of 1 indicates that the packet type field is a first type field, where the value field is used to indicate a device identifier of the access network device, and optionally, the device identifier is a MAC address of the access network device, the value field occupies 6 bytes, and the length field of 6. The type field 10 indicates that the packet type field is a second type field, and in this case, the value field is used to indicate neighbor information of the access network device, where the neighbor information includes an access location and/or a device type of the access terminal in this embodiment. The length of the byte occupied by the value field is variable, the value of the length field is variable, and the length of the byte actually occupied by the value field is variable. In addition, when the type field is 0, the value field is used to indicate the end of the ethernet frame.

When the type field is 10, the value field includes contents as shown in fig. 13, and the value field includes at least a neighbor number (neighbor num) field and a neighbor list (neighbor list) field. The field of the number of neighbors usually occupies a length of one byte, and in this embodiment, the field is used to indicate the number of access terminals connected to the access network device.

For example, in fig. 13, the neighbor list field includes K neighbor parameters, and K ≧ 1, the number of neighbors field is K.

The format of each neighbor parameter is shown in fig. 14, and the fields and the field meanings included in the neighbor parameters are as follows:

4. A remote port identification (remote port ID) field for indicating information of a network port connected to the network device in the neighbor network device, and in this embodiment, for indicating information of a network port used for connecting to the access network device in the access terminal. The remote port identification field includes a port identification length (port ID length) field and a port identification (port ID) field, and the meaning of the field may be combined with the local port identification field, which is not described in this embodiment again.

5. A remote link aggregation ID (remote link aggregation ID) field usually occupies 2 bytes, and is used to indicate a port identifier of a port obtained by link aggregation to which a network port connected to the local network device belongs in a neighbor network device. When the remote link aggregation identifier is 0xFFFF, it indicates that a network port used for connecting with the home network device in the neighbor network device is not added to a port obtained by link aggregation.

6. A device type (device type) field, which usually occupies one byte, is used to indicate the device type of the access terminal, and when the field is 1, the indicated device type is WAP, and when the field is 0, the indicated device type is the wired access terminal.

For example, taking the network topology shown in fig. 8 as an example, assuming that the access network device 330 receives an LLDP frame sent by the access terminal 351, and TLV triplets included in the received LLDP frame are shown in fig. 9, the content included in an ethernet frame in a CAPWAP message sent by the access network device 330 to the management network device 310 is shown in fig. 15. Where MAC 2 is the device identification of the access network device 330 and GE0/0/2 is the port identification of the port 332 in the access network device 330 for connection to the access terminal 351.

Step 503, the management network device receives the access parameter of the access terminal sent by the access network device.

Correspondingly, the management network equipment receives the access parameters sent by the access network equipment by using the CAPWAP protocol.

Step 504, the management network device determines configuration parameters corresponding to the device type according to the preset corresponding relationship.

Step 505, the management network device determines a service path with an access position included in the access parameter as an endpoint according to the network topology and the parameter type.

Assuming that the network topology is as described above in fig. 8, and the configuration parameter corresponding to the access terminal 351 determined by the management network device 310 is VLAN 100, the traffic path determined by the management network device 310 is the network path between the management network device 310 and the access terminal 351. That is, the traffic path is, port 311 of the management network device 310 → port 321 of the relay network device 320 → port 322 of the relay network device 320 → port 331 of the access network device 330 → port 332 of the access network device 330 → port 3511 of the access terminal 351.

In step 506, the managing network device determines the network ports of the network devices in the traffic path.

Step 507, the management network device generates a configuration instruction corresponding to the network device according to the network port and the configuration parameters of each network device.

The configuration instruction is used for instructing at least one network device to perform configuration according to the configuration parameters and the port identifier, wherein the port identifier is an identifier of a network port located in a service path in the network device.

Optionally, the management network device sends a configuration instruction to each network device in the service path using a CAPWAP protocol, and the management network device sends a CAPWAP packet to each network device, where the CAPWAP packet carries the configuration instruction, and the configuration instruction is encapsulated in a format of a TLV triple, where the format of the CAPWAP packet is as shown in fig. 10. The configuration instructions are carried in ethernet frames, the format of which is shown in figure 11 above.

Optionally, the configuration instruction includes at least one group of packet type field and parameter field, and optionally, the group of packet type field, parameter field, and packet length field are added into one TLV triplet. The type field in the TLV triple is a message type field, the length field is a message length field, and the value field is a parameter field. When the message type field is a first type field, the parameter fields in the same group are used for indicating configuration parameters; when the message type field is the second type field, the parameter field of the same group is used for indicating the port identification of the network port.

And when the parameter types corresponding to the configuration parameters are different, the values of the first type fields are different. When the format of the TLV in the ethernet frame is as shown in fig. 12, the message type fields indicated by type field 11, type field 13, and type field 14 are all the first type fields. When the type field is 11, the configuration parameter indicated by the value field is VLAN id. When the type field is 13, the configuration parameter indicated by the value field is IGMP snooping, when the value field is 1, IGMP snooping is enabled, and when the value field is 0, IGMP snooping is disabled. When the type field is 14, the configuration parameter indicated by the value field is DHCP snoop, the value field 1 indicates DHCP snoop is enabled, and the value field 0 indicates DHCP snoop is disabled. The type field of the packet indicated by 2 is a second type field, and in this case, the value field is used to indicate the port identifier of the network port. In addition, when the type field is 0, the value field is used to indicate the end of the ethernet frame. When the configuration parameter is the VLAN identifier, the ethernet frame further includes a TLV for indicating a parameter configuration mode, where the parameter configuration mode includes an add-allowed mode or a default mode, the add-allowed mode is used for indicating that the network device allows the service data added with the VLAN identifier to pass through, and the default mode is used for indicating that the network device configures a default VLAN to be a VLAN corresponding to the VLAN identifier. For example, in fig. 12, when the type field is 12, the value field is used to indicate the parameter configuration mode, when the value field is 1, the value field is used to indicate that the parameter configuration mode is the default mode, and when the value field is 0, the value field is used to indicate that the parameter configuration mode is allowed to join.

Step 508, the managing network device sends a configuration instruction to at least one network device in the traffic path.

In step 509, the access network device receives the configuration command sent by the management network device.

Optionally, the access network device receives the configuration instruction sent by the management network device by using the CAPWAP protocol.

Step 510, the access network device configures with the configuration parameters indicated by the configuration instruction.

Optionally, after the access network device is configured according to the configuration parameter and the network port, the access network device processes the service data received and/or sent from the network port.

Optionally, when the configuration parameter indicated by the configuration instruction includes a VLAN identifier and indicates an access location, the parameter configuration mode indicated by the configuration instruction is usually a default mode. When the configuration parameter indicated by the configuration instruction includes a VLAN id and indicates a network port for connecting to another network device, the configuration mode of the parameter indicated by the configuration instruction is usually to allow joining. The access network device receives and/or transmits the service data added with the VLAN identification through the network port after the configuration is carried out according to the configuration instruction, and adds the VLAN identification to the service data received through the access position.

Optionally, the configuration parameter indicated by the configuration instruction includes a VLAN identifier and an IGMP snooping enable message, the management network device sends the configuration instruction for indicating the VLAN identifier to each network device, and the management network device also sends the configuration instruction for indicating the IGMP snooping enable message to the access network device, and the access network device enables the IGMP snooping according to the configuration instruction.

In step 511, the relay network device receives the configuration command sent by the management network device.

Step 512, the relay network device configures with the configuration parameters indicated by the configuration instruction.

When the service path includes multiple relay network devices, each relay network device receives the configuration instruction and performs configuration through the methods shown in steps 511 and 512, and the method for the relay network device to perform configuration according to the configuration parameters indicated by the configuration instruction may be combined with the method for performing configuration by the access network device shown in step 510, which is not described again in this embodiment. In addition, the above steps 511 and 512 are optional, and when the relay network device is not included in the service path, the step 511 and the step 512 are not included in the parameter configuration method.

After each network device in the service path is configured according to the configuration parameters indicated by the configuration instruction, at least one network device in the service path may forward the service to the access terminal.

In the parameter configuration method provided by the embodiment of the application, after an access terminal is connected with an access network device, the access network device determines and sends an access position of the access terminal to a management network device, and the management network device determines a service path according to the access position; the problem that when a network administrator conducts parameter configuration on network equipment related to the access terminal in advance, if the access terminal is actually connected to other access positions in the access network equipment, the parameter configuration needs to be conducted on the network equipment again, and therefore the parameter configuration is not flexible enough is solved, and the flexibility of the parameter configuration is improved.

In the parameter configuration method provided by the embodiment of the application, after an access terminal is connected with an access network device, the access network device receives a device type sent by the access terminal through an LLDP, a management network device determines a configuration parameter according to the device type, and then sends a configuration instruction indicating the configuration parameter to each network device; when the device type of the access terminal connected with the access network device changes, the management network device can determine new configuration parameters and re-instruct each network device to configure according to the new configuration parameters, so that the problem that the network device cannot forward the service data to the new access terminal according to the pre-configuration of the network administrator when the device type of the actually accessed access terminal changes after the network administrator performs parameter configuration on the network device in advance is solved.

For example, the access terminal 351 is a WAP, taking as an example that the access terminal is the access terminal 351 in the network topology shown in fig. 8. The access parameters carried in the CAPWAP message sent by the access network device 330 to the management network device 310 are as described above in fig. 15. The configuration parameter corresponding to the device type determined by the managing network device 310 is VLAN 100. The traffic path determined by the managing network device 310 is as shown in step 505 above. The managing network device sends configuration instructions to the relay network device 320 and the access network device 330 included in the traffic path. After the relay network device 320 is configured according to the configuration instruction, it allows the traffic data added with the VLAN 100 to be received and/or transmitted from the port 321, and allows the traffic data added with the VLAN 100 to be received and/or transmitted from the port 322. After the access network device 330 is configured according to the configuration instruction, it allows the traffic data added with the VLAN 100 to be received and/or transmitted from the port 331, and adds the VLAN 100 to the traffic data received from the port 332, and allows the traffic data added with the VLAN 100 to be transmitted from the port 332.

In another illustrative example, where the access terminal is an access terminal 354 in the network topology shown in fig. 8, the access terminal 354 is a set-top box. The format of the access parameter carried in the CAPWAP message sent by the access network device 340 to the management network device 310 is similar to that in fig. 15, and is not described again in this embodiment. The configuration parameters corresponding to the device type determined by management network device 310 include VLAN10 and IGMP snooping enabled. The traffic path determined by the managing network device 310 includes a network path of the managing network device's port 311 → the relaying network device 320's port 321 → the relaying network device 320's port 323 → the access network device 340's port 341 → the access network device 340's port 343 → the access terminal 354's port 3541, and a network path of the access network device 340's port 343 → the access terminal 354's port 3541. The management network device 310 sends a configuration instruction for indicating the VLAN10 to the relay network device 320 and the access network device 340 included in the traffic path, and then the relay network device 320 and the access network device 340 are configured according to the VLAN10, as shown in the foregoing exemplary embodiment, which is not described again in this embodiment. In addition, the management network device 310 further sends a configuration instruction indicating IGMP snooping is enabled to the access network device 340, and the access network device 340 further sends the received traffic data to the access terminal 354 through the port 343 according to the configuration instruction enabling IGMP snooping.

Optionally, the neighbor network device enables LLDP, and the neighbor network device adds its own device address and port identifier to a TLV triplet in the LLDP data unit, and sends the TLV triplet to the network device.
