Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic flow chart of a port migration method according to an embodiment of the present invention is shown in fig. 1, where the port migration method may include the following steps:
it should be noted that, the sequence numbers of the steps in the embodiment of the present invention do not mean the execution sequence, and the execution sequence of each process should be determined by the function and the internal logic of the process, and should not constitute any limitation to the implementation process of the embodiment of the present invention.
In the embodiment of the invention, in order to realize automatic port migration, the equipment with service connection can send a port migration detection message to the opposite equipment through the port with service connection.
For example, for any service port, when the service port UP (open), the port migration detection packet may be sent to the peer device through the service port at regular time.
For example, the port migration detection packet sent through any service port may carry port identification information of the service port and device identification information of the local device.
Similarly, for any device, a port migration detection packet sent by the peer device may also be received through the local service port, where the port migration detection packet may carry device identification information (referred to as first device identification information) for identifying the peer device and port identification information (referred to as first port identification information) for identifying a service port (referred to as a first port) of the peer device that sends the port migration detection packet.
In the embodiment of the present invention, for any service port, an information table (referred to as a port migration detection information table herein) may be established for a service connection between the service port and a corresponding service port of an opposite-end device (which may be referred to as an opposite-end service port), where the port migration detection information table may be used to record port identification information of the service port (which may be referred to as a local service port), port identification information of the opposite-end service port, and device identification information of a device to which the opposite-end service port belongs.
Correspondingly, when a port migration detection message sent by an opposite-end device is received, first device identification information and first port identification information carried in the port migration detection message may be acquired, and according to the first device identification information and the first port identification information, a port migration detection information table may be queried to determine whether a port migration detection information table (referred to herein as a target port migration detection information table) matching the first device identification information and the first port identification information exists, that is, the recorded port identification information of the opposite-end service port is the first port identification information, and the device identification information of the device to which the opposite-end service port belongs is the port migration detection information table of the first device identification information.
103, when a target port migration detection information table matched with the first equipment identification information and the first port identification information is inquired, determining whether a port migration condition is met according to the second port identification information; the second port identification information is the port identification information of the local service port recorded in the target port migration detection information table.
In the embodiment of the present invention, when a target port migration detection information table matching with the first device identification information and the first port identification information is queried, whether a port migration condition is satisfied or not may be determined according to port identification information (referred to as second port identification information herein) of a local service port recorded in the target port migration detection information table, so as to determine whether port automatic migration is required or not.
In an example, if a matching port migration detection information table is not queried according to the first device identification information and the first port identification information, that is, the target port migration detection information table does not exist, a port migration detection information table corresponding to the first device identification information and the first port identification information may be created, where the port migration detection information table may include the first device identification information, the first port identification information, and port identification information of a local service port that receives the port migration detection packet.
And step 104, carrying out service configuration synchronization on the service ports before and after migration when the port migration condition is determined to be met.
In the embodiment of the invention, when the port migration condition is determined to be met, service configuration synchronization can be carried out on the service ports before and after migration, namely, the service configuration of the port before migration is synchronized to the port after migration.
For example, after completing the service configuration synchronization, the service configuration of the port before migration may be deleted.
For example, assuming that the port migration is port 1 to port 2, the traffic configuration of port 1 may be synchronized to port 2, and the traffic configuration of port 1 may be deleted.
It can be seen that, in the method flow shown in fig. 1, a port migration detection message is exchanged between devices with service connection through a service port, and a port migration detection information table is maintained, when a port migration detection message of an opposite device is received, a matching port migration detection information table is queried according to device identification information and port device identification carried in the port migration detection message, and when a port migration condition is satisfied according to port identification information of a local service port recorded in the queried matching port migration detection information table under the condition that the matching port migration detection information table is queried, service configuration synchronization is performed on service ports before and after migration, so that automatic migration of the ports is realized, and efficiency and accuracy of port migration are improved.
In some embodiments, in step 104, satisfying the port migration condition may include:
the third port identification information is inconsistent with the second port identification information; the third port identification information is used for identifying a third port, and the third port is a service port of the local terminal device which receives the port migration detection message.
In this embodiment, when the target port migration detection information table is matched according to the first device identification information and the first port identification information, the second port identification information may be compared with the port identification information (referred to as third port identification information herein) of the service port, where the local device receives the port migration detection packet.
If the third port identification information is inconsistent with the second port identification information, it can be determined that the port migration condition is satisfied, and service configuration synchronization is performed on the service ports before and after migration.
For example, if the third port identification information is consistent with the second port identification information, it may be determined that the port migration condition is not satisfied, and the port migration process may not be required.
In an example, for any local service port of the local end device, the port migration detection information table corresponding to the local service port is further used for recording service configuration check information;
The service configuration check information includes service configuration check information of the opposite service port recorded in the port migration detection information table, and in step 104, the method meets the port migration condition, and may further include:
the second service configuration checking information is consistent with the first service configuration checking information; the port migration detection message also carries first service configuration check information, and the first service configuration check information is determined by the opposite terminal device according to the service configuration information of the first port; the second service configuration check information is service configuration check information of an opposite service port recorded in a target port migration detection information table, and the service configuration check information of the opposite service port is determined by the device to which the opposite service port belongs according to the service configuration information of the opposite service port;
and/or the presence of a gas in the gas,
the service configuration check information includes the service configuration check information of the local service port recorded in the port migration detection information table, and in step 104, the method that meets the port migration condition may further include:
the fourth service configuration verification information is consistent with the fifth service configuration verification information; the fourth service configuration check information is service configuration check information of a second port recorded in the target port migration detection information table, the second port is a local service port identified by second port identification information, the service configuration check information of the second port is determined by the local terminal device according to the service configuration information of the second port, and the fifth service configuration check information is determined by the local terminal device according to the current service configuration information of the second port.
In this example, considering that when the service configuration of one of the two service ports with service connection is changed but the service configuration of the other service port is not changed in a matching manner, service interaction between the two service ports may not be performed, or even an error occurs, in order to ensure the security of service configuration synchronization during automatic port migration, when the ports are migrated automatically, the service configuration of the service ports may be checked, and whether a port migration condition is satisfied is determined according to a result of the service configuration check.
Correspondingly, the port migration detection information table may further record service configuration check information.
For any port migration detection information table, the service configuration check information recorded in the port migration detection information table may include service configuration check information of an opposite service port recorded in the port migration detection information table, and/or service configuration check information of a local service port recorded in the port migration detection information table.
Taking as an example that the service configuration check information recorded in the port migration detection information table may include service configuration check information of an opposite service port recorded in the port migration detection information table, and service configuration check information of a local service port recorded in the port migration detection information table.
The port migration detection packet may also carry service configuration check information (referred to as first service configuration check information herein) of the first port, where the first service configuration check information is determined by the peer device according to the service configuration information of the first port.
For example, the service configuration Check information may be calculated by the device according to the service configuration information of the local service port by using a specified Algorithm (e.g., a Message-Digest Algorithm (MD 5), a Cyclic Redundancy Check (CRC) Algorithm, etc.).
Wherein, the same service configuration information is calculated by the appointed algorithm to obtain the same result; different service configuration information is calculated by the specified algorithm to obtain different results.
When the matched target port migration detection information table is queried according to the first device identification information and the first port identification information, on one hand, the service configuration information (referred to as second service configuration check information herein) of the opposite-end service port recorded in the target port migration detection information table may be compared with the first service configuration check information carried in the port migration detection packet to determine whether the service configuration information of the opposite-end service port changes.
On the other hand, the present service configuration information of the local service port may be queried according to the port identification information of the local service port recorded in the target port migration detection information table, and corresponding service configuration check information (referred to as fifth service configuration check information herein) is determined according to the service configuration information, and the fifth service configuration check information is compared with the service configuration information (fourth service configuration check information herein) of the local service port (i.e., the second port) recorded in the target port migration detection information table, so as to determine whether the service configuration information of the second port changes.
When the third port identification information is inconsistent with the second port identification information, the second service configuration check information is consistent with the first service configuration check information, and the fourth service configuration check information is consistent with the fifth service configuration check information, that is, the local service port having service connection with the opposite service port is changed, but the service configuration information of the opposite service port and the service configuration information of the original local service port (the local service port corresponding to the port identification information of the local service port recorded in the port migration detection information table) are not changed, it can be determined that the port migration state is satisfied.
When any one of the third port identification information and the second port identification information is inconsistent, the second service configuration verification information and the first service configuration verification information are consistent, and the fourth service configuration verification information and the fifth service configuration verification information are consistent is not satisfied, it can be determined that the port migration condition is not satisfied, and the port migration processing is not performed.
As can be seen, when the port migration detection packet carries service configuration check information (such as the first service configuration check information), and the port migration detection information table records service configuration check information (such as service configuration check information of an opposite-end service port and/or service configuration check information of a local service port), it may be determined whether a port migration condition is satisfied according to the second port identification information and the service configuration check information carried in the port migration detection packet, so as to improve the security of automatic port migration.
In one example, when any one of the information recorded in the target port migration detection information table except for the first device identification information and the first port identification information is changed, the corresponding information recorded in the target port migration detection information table may be updated to the changed information.
In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present invention, the technical solutions provided by the embodiments of the present invention are described below with reference to specific examples.
In this embodiment, in order to implement automatic port migration, a conventional LLDP packet may be extended, and a new TLV (Type/Length/Value) for carrying service configuration check information is added to check the service configuration of the device port, so as to ensure security.
The newly added TLV (which may be referred to as Configuration MD5 TLV) may be an unused, reserved basic TLV type in the LLDP protocol, or an enterprise private newly added customization in the defined TLV type is organized.
In this embodiment, the device identification information is a Chassis ID (subrack identification), and the Port identification information is a Port ID (Port identification) as an example.
In this embodiment, for example, the Port migration detection information table (may also be referred to as a service configuration check information table) records device identification information of the peer device, Port identification information of the peer service Port, service configuration check information of the peer service Port, Port identification information of the Local service Port (may be referred to as a Local Port ID), and service configuration check information of the Local service Port.
Referring to fig. 2A, a schematic structural diagram of a specific application scenario provided in the embodiment of the present invention is shown in fig. 2A, where the specific application scenario may include a device 210 and a device 220, and the device 210 establishes a service connection with a service port 221 of the device 220 through a service port 211.
Assuming that the device identification information of the device 210 is chatiss a, and the port identification information of the service port 211 of the device 210 is port 1; the port identification information of service port 221 of device 220 is port 1.
Based on the application scenario shown in fig. 2A, taking the implementation flow at the device 220 side as an example:
when the service port 221IUP of the device 220 is used, the device 220 may calculate an MD5 value (i.e., the service configuration check information) according to the service configuration information of the service port 221.
Optionally, in order to improve controllability of the port auto-migration scheme and improve compatibility of the port auto-migration scheme with a conventional port migration scheme, the port auto-migration function (which may also be referred to as an LLDP auto-migration function) may be selectively enabled or disabled according to requirements.
When the LLDP automatic migration function is enabled, carrying out the port automatic migration flow according to the scheme provided by the embodiment of the invention; when the LLDP auto-migration function is not enabled, port migration may be implemented according to a conventional scheme, and at this time, when sending an LLDP packet, the new Configuration MD5 TLV is not carried (i.e., sending a normal LLDP packet).
The following description will be made by taking an example of enabling the LLDP auto-migration function.
In this embodiment, when the MD5 value of the service Configuration information of the port 221 is determined, the device 220 may send, to the device 210 through the port 221, an LLDP packet carrying the Configuration MD5 TLV (i.e., the port migration detection packet described above).
Alternatively, after the port 221UP, the device 220 may start a periodic transmission timer, and when the periodic transmission timer expires, transmit the LLDP packet, and reset the periodic transmission timer.
The sending flow of the LLDP packet may be as shown in fig. 3.
The implementation process of the device 210 sending the LLDP message through the port 211 is similar to the implementation process of the device 220 sending the LLDP message through the port 221.
In this embodiment, when the device 220 receives, through the Port 221, the LLDP packet sent by the device 210 through the Port 211, it may obtain the value MD5 in the sessions ID (i.e., sessions a), Port ID (i.e., Port1) and Configuration MD5 TLV in the LLDP packet.
When the device 220 does not enable the LLDP auto-migration function, or the LLDP message does not carry the Configuration MD5 TLV, the device 220 may process the LLDP message according to a normal LLDP message processing flow.
In this embodiment, the device 220 may query the local port detection information table with chatsis a and port1 to determine whether there is a matching port migration detection information table, that is, the recorded device identification information of the peer device is chatsis a, and the device identification information of the peer device is the port migration detection information table of port1 (that is, the target port migration detection information table).
Assume that device 220 queries the target port migration detection information table, the information of which is shown in table 1:
TABLE 1
Wherein, the config1_ MD5 is calculated by the device 210 according to the service configuration information of the port 211 by using an MD5 algorithm; config2_ MD5 is calculated by device 220 using the MD5 algorithm according to the traffic configuration information of port 221.
It should be noted that, when the device 220 does not query the target port migration detection information table, the port migration detection information table shown in table 1 may be created.
Similarly, the port migration detection information table in the device 210 may be shown in table 2:
TABLE 2
In this embodiment, after querying the target port migration detection information table, the device 220 may query current service Configuration information of the local service port (i.e., the port 221) according to port identification information of the local service port recorded in the target port migration detection information table, calculate service Configuration checking information by using an MD5 algorithm according to the current service Configuration information of the port 221, and determine whether a port migration condition is satisfied according to the calculated service Configuration checking information, the service Configuration checking information (MD 5 value in Configuration MD5 TLV) carried in the received LLDP message, and the target port migration detection information table.
Wherein, satisfying the port migration condition comprises:
1. the port identification information of the service port of the LLDP packet carrying the Configuration MD5 TLV, which is received by the device 220, is inconsistent with the port identification information of the local service port recorded in the target port migration detection information table;
2. the service Configuration check information in the LLDP message carrying Configuration MD5 TLV received by the device 220 is consistent with the service Configuration check information of the opposite service port recorded in the target port migration detection information table;
3. according to the port identification information of the local service port recorded in the target port migration detection information table, inquiring the current service configuration information of the local service port, and calculating by using an MD5 algorithm to obtain an MD5 value, which is consistent with the service configuration verification information of the local service port recorded in the target port migration detection information table.
When the device 220 queries the matching target port migration detection information table according to the device identification information and the port identification information in the received LLDP message and determines that the port migration condition is satisfied, service configuration synchronization is performed on the service ports before and after migration.
For example, referring to fig. 2B, assume that at some point, port 221 of device 220 fails (Down) and the traffic connection between device 220 and port 211 of device 210 is migrated to port 222.
Assume that the port identification information of port 222 is port2, and the current service configuration information of port 222 is def _ config.
When the device 220 receives, through the port 222, the LLDP packet carrying the Configuration MD5 TLV sent by the device 210 through the port 211, it may query the local port migration detection information table according to the device identification information (i.e., sessions a) and the port identification information (i.e., port1) carried in the LLDP packet, and determine that there is matching target port migration detection information, i.e., the port migration detection information table shown in table 1.
The device 220 may compare the port identification information (port2) of the service port that receives the LLDP packet with the port identification information (i.e., port1) of the local service port recorded in the port migration detection information table shown in table 1, the MD5 value (assumed to be config1_ MD5) in the Configuration MD5 TLV carried in the LLDP packet, and the service Configuration check information (i.e., config1_ MD5) of the opposite service port recorded in the port migration detection information table shown in table 1, and the config2_ MD5 and the service Configuration check information (i.e., config2_ MD5) of the local service port recorded in the port migration detection information table shown in table 1, respectively, and find that the above-mentioned port migration condition is satisfied, at this time, the device 220 may perform automatic migration of the port, synchronize the service Configuration information of the port 221 to the port 222, and delete the service Configuration information of the port 221.
The device 220 may update the port migration detection information table recorded in table 1, where the updated port migration detection information table may be as shown in table 3:
TABLE 3
In this embodiment, when the device 210 receives, through the port 211, the LLDP packet carrying the Configuration MD5 TLV sent by the device 220 through the port 222, the device identification information (sessions B) and the port identification information (port2) carried in the LLDP packet are obtained, and the local port migration detection information table is queried according to the device identification information and the port identification.
If a matching port migration detection information table is not found, the device 210 may create a corresponding port migration detection information table and create a port migration detection information table as shown in table 4 (assuming that port migration is not completed at this time):
TABLE 4
The def _ config _ MD5 is calculated by the device 220 according to the service configuration information (i.e., def _ config) of the port 220 before the port migration is completed, using the MD5 algorithm.
When the device 220 completes the automatic port migration and the device 210 receives the LLDP packet carrying the Configuration MD5 TLV sent by the device 220 through the port 222 through the port 211 again, the matching target port migration detection information table, that is, the port migration detection information table shown in table 4, is queried according to the device identification information (sessions B) and the port identification information (port2) carried in the LLDP packet.
The device 210 may compare the port identification information (port1) of the service port that receives the LLDP packet with the port identification information (i.e., port1) of the local service port recorded in the port migration detection information table shown in table 4, the MD5 value (assumed to be config2_ MD5) in the Configuration MD5 TLV carried in the LLDP packet, and the service Configuration verification information (i.e., def _ config _ MD5) of the opposite service port recorded in the port migration detection information table shown in table 4, and the service Configuration verification information (i.e., config1_ MD5) of the local service port recorded in the port migration detection information table shown in table 4, and when it is found that the port migration detection condition is not satisfied, the device 210 may update the port migration detection information table shown in table 4.
The updated port migration detection information table may be as shown in table 5:
TABLE 5
The flow of receiving the LLDP packet may be as shown in fig. 4.
It can be seen from the above description that, in the technical solution provided in the embodiment of the present invention, a port migration detection message is exchanged between devices connected by a service port, and a port migration detection information table is maintained, when a port migration detection message of an opposite device is received, a matching port migration detection information table is queried according to device identification information and a port device identification carried in the port migration detection message, and when a matching port migration detection information table is queried, service configuration synchronization is performed on service ports before and after migration when it is determined that a port migration condition is satisfied according to port identification information of a local service port recorded in the queried matching port migration detection information table, so that automatic migration of the ports is realized, and efficiency and accuracy of port migration are improved.
