Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In view of the above objects, a first aspect of the embodiments of the present invention provides an embodiment of a system for configuring a network time synchronization tool based on a switch.
As shown in fig. 1, the system includes a configuration issuing module 10, a configuration management module 20, an execution module 30, and a monitoring module 40. The execution logic of each module is as follows:
the configuration issuing module 10 creates a first information table in a database, and writes information related to a configuration network time synchronization tool into the first information table, wherein the information includes a source interface device name or a source IP address of an access switch and virtual routing forwarding information;
the configuration management module 20 monitors the first information table, and obtains a source interface device name or a source IP address in the first information table in response to a change of the first information table;
the configuration management module 20 generates a configuration file required by the network time synchronization tool according to the source interface device name or the source IP address and a preset template, and creates a second information table in the database after the configuration file is generated;
the execution module 30 is configured to monitor the second information table, and in response to a change in the second information table, obtain a source interface device name or a source IP address and virtual routing forwarding information from the first information table;
the execution module 30 determines whether the virtual routing forwarding information is empty based on the source interface device name or the source IP address, and starts a network time synchronization service based on the configuration file correspondingly based on the determination result;
the monitoring module 40 monitors the source interface or the source IP address configured by the network time synchronization tool in the database and the real-time status forwarded by the virtual router to update the database in real time.
More specifically, a configuration issuing module, a configuration management module, an execution module and a monitoring module are deployed on a switch, and the switch is a white box switch. As shown in fig. 2, an interaction flow diagram of internal modules of a system for configuring a network time synchronization tool based on a switch is provided, where the working and interaction flows of each module are specifically as follows:
the configuration issuing module writes information required by NTP configuration into a first information table of the database, assuming that the first information table is defined as NTP _ SOURCE, the information specifically includes a SOURCE interface device name or a SOURCE IP address and vrf (virtual routing forwarding) information, and the SOURCE interface device name and the SOURCE IP address are configured in an overlay manner, that is, the old configuration is newly configured to overlay.
The configuration issuing module is responsible for creating the NTP _ SOURCE table. When a user configures an interface or an IP address, an NTP _ SOURCE table is created and the active state defaults to in-active. The module checks whether the IP address of the interface is available, if the IP address can be normally used, the interface state is enable, otherwise, the interface state is disable.
After the source interface or the source IP address is configured, the subsequent ntp service can automatically query vrf where the source interface or the source IP address is located according to the source interface device name or the source IP address in the database, and bind the ntp service to the vrf for operation.
After the initialization (namely after the startup) is completed, the configuration management module monitors an NTP _ SOURCE table in the database, automatically acquires SOURCE interface information or SOURCE IP address information in the NTP _ SOURCE table when the table is found to be changed, and regenerates an NTP required configuration file ntp.conf according to the SOURCE interface information or the SOURCE IP address information in the table and a preset template. After the configuration file is generated, a second information table is created in the database, and it is assumed that the second information table is defined as NTP _ CONF _ DONE, where the NTP _ CONF _ DONE table may be empty.
After the execution module is started, monitoring an NTP _ CONF _ DONE table, reading the NTP _ SOURCE table after monitoring that the table is changed, namely the NTP _ CONF _ DONE table is deleted and/or created, acquiring SOURCE interface or SOURCE IP address information, and acquiring vrf information according to the SOURCE interface or SOURCE IP address information. If no vrf information exists, directly starting the ntp service; if vrf information exists, a corresponding cgroup device is created based on a cgroup mechanism provided by kernel, and the ntp service is bound to the device for execution.
When the system is started, the monitoring module is started in a service mode, monitors vrf table entries and three-layer interface table entries in the database after the system is started, and compares the monitored vrf information and/or three-layer interface information with the SOURCE interface information or the SOURCE IP address information in the NTP-SOURCE and completes the modification of the NTP-SOURCE table in the database and the reconfiguration of the NTP service when the monitored table entries are changed.
The interaction of the ntp message is carried out through three layers of interfaces, each three layer of interface carries out message forwarding in vrf, so that when the ntp message is monitored on one three layer of interface, vrf domain to which the interface belongs needs to be considered, and the ntp message can be normally forwarded in vrf. vrf as the master device of the interface needs to be configured according to the actual application situation, which results in that vrf where the interface is located may change with the change of the application or the network, so that it needs to monitor this situation through the monitoring module, and when the monitored interface and/or vrf changes, the ntp service is reset.
The configuration of the switch ntp is realized through a configuration issuing module, a configuration management module, an execution module and a monitoring module which are deployed on the switch. After the configuration is completed, the exchanger sends/receives the ntp message interaction through the configured source IP address or the source interface, redundant ntp messages can be effectively filtered, ntp configuration can be automatically updated according to the change of the configured source IP address or the vrf where the source interface is located, and the validity of ntp configuration is guaranteed in real time.
In some embodiments, initiating a network time synchronization service based on the profile based on the determination result accordingly comprises:
in response to the virtual route forwarding information not being empty, creating a corresponding cgroup device based on the virtual route forwarding information, and binding a network time synchronization service to the cgroup device to start the network time synchronization service at the cgroup device based on the configuration file;
and responding to the virtual route forwarding information is empty, and starting network time synchronization service based on the configuration file.
In one embodiment, the configuration management module is responsible for generating the configuration file ntp. And the configuration management module monitors the NTP-SOURCE table, and if the table is found not to exist in the database, the management interface is used as a SOURCE interface, and ntp.conf is generated according to a preset template, wherein the template is a default template. If the table is found to exist in the database or the table is changed, the information in the table is taken out. If the acquired information is the interface name (namely the name of the SOURCE interface device written in the NTP _ SOURCE table before), the acquired interface is used as the SOURCE interface, ntp.conf is generated according to a preset template, the state of the SOURCE interface is marked as active, and after the ntp.conf is generated, the NTP _ CONF _ DONE table is created in the database. And if the acquired information is the IP address, the acquired IP address is used as a source IP address, ntp.conf is generated according to a preset template, the state of the source IP address is marked as active, and after the ntp.conf is generated, an NTP _ CONF _ DONE table is created in the database.
The execution module is responsible for starting the ntp service according to the configuration. The execution module monitors the NTP _ CONF _ DONE table created by the configuration management module. Reading the NTP _ SOURCE table after monitoring that the NTP _ CONF _ DONE table is changed, acquiring SOURCE interface or SOURCE IP address information, acquiring vrf information according to the SOURCE interface or SOURCE IP address information, and directly starting an NTP service if the acquired vrf information is null; and if the obtained vrf information is not null, creating corresponding cgroup equipment based on a cgroup mechanism provided by kernel, and binding the ntp service to the cgroup equipment for starting.
In some embodiments, obtaining the source interface device name and the virtual routing and forwarding information from the first information table, and determining whether the virtual routing and forwarding information is null based on the source interface device name includes:
in response to the first information table containing the source interface device name, searching whether a corresponding interface information table exists in the database based on the source interface device name;
in response to the existence of the corresponding interface information table, checking whether the corresponding interface information table has an IP address;
and responding to the IP address of the corresponding interface information table, acquiring corresponding virtual route forwarding information from the first information table, and judging whether the corresponding virtual route forwarding information is empty or not.
In some embodiments, obtaining the source IP address and the virtual routing forwarding information from the first information table, and determining whether the virtual routing forwarding information is null based on the source IP address comprises:
responding to the first information table containing the source IP address, acquiring the source IP address from the first information table, and searching whether a corresponding interface information table exists in the database based on the source IP address;
and responding to the existence of the corresponding interface information table, acquiring corresponding virtual route forwarding information from the first information table based on the source interface equipment name in the corresponding interface information table, and judging whether the corresponding virtual route forwarding information is empty or not.
In one embodiment, the execution module is responsible for initiating the ntp service according to the configuration. The module preconfigures NTP services and starts the services by monitoring the NTP _ CONF _ DONE table created by the configuration management module. The specific execution operation is as follows:
1) And after the initialization of the execution module is completed, monitoring the NTP _ CONF _ DONE table.
2) If the NTP _ CONF _ DONE table does not exist, the NTP service is directly started.
3) If the NTP _ CONF _ DONE table exists, data in the NTP _ SOURCE table is acquired.
4) And if the data acquired from the NTP-SOURCE table is the name of the SOURCE INTERFACE equipment, inquiring whether a corresponding INTERFACE table exists in a database according to the name of the SOURCE INTERFACE equipment. Taking the name of the source INTERFACE device as Loopback0 as an example, inquiring whether an INTERFACE | Loopback0 table exists or not, and if not, returning an error; if yes, checking whether the Loopback0 has an IP address, and if not, returning an error; if yes, whether vrf related configuration exists in the table is inquired, and if not, ntp service is directly started; if Vrf is configured, taking Vrf1 as an example, creating a cgroup device corresponding to Vrf1, performing initialization setting, binding the ntp service to the device after the setting is completed, and starting, at this time, the ntp service will use the first IP address of the interface as the source IP address to communicate with the ntp server.
5) And if the data acquired from the NTP-SOURCE table is an IP address (namely a SOURCE IP address), inquiring whether a corresponding INTERFACE table exists in the database according to the SOURCE IP address. Taking the source IP address as 1.1.1.1 as an example, inquiring whether an INTERFACE |1.1.1.1 table exists or not, if not, returning an error; if yes, taking INTERFACE | Loopback0|1.1.1.1 as an example, inquiring whether vrf related configuration exists in INTERFACE | Loopback0 corresponding to the table, and if not, directly starting ntp service; if Vrf is configured, taking Vrf1 as an example, creating a cgroup device corresponding to Vrf1, performing initialization setting, and binding ntp service to the device to start after the setting is completed.
In some embodiments, monitoring a real-time status of a source interface or a source IP address configured by the network time synchronization tool and virtual route forwarding in the database to update the database in real-time comprises:
monitoring a virtual route forwarding information table and a three-layer interface information table in the database;
responding to the change of the virtual routing forwarding information table and/or the three-layer interface information table, acquiring a corresponding interface device name and a corresponding operation from the three-layer interface information table, correspondingly modifying the source interface device name or the source IP address and the virtual routing forwarding information in the first information, and resetting network time synchronization service, wherein the operation comprises any one of adding the interface device into a corresponding virtual network route, removing the interface device from the corresponding virtual network route, and deleting the virtual network route.
In one embodiment, the monitor module is responsible for monitoring the ntp configured interface and the real-time status of vrf, and completing the update of the database. Take the configured source interface Loopback0, IP address 1.1.1.1 as an example. This module triggers a reset operation by listening to the VRF TABLE and INTF _ TABLE TABLEs in the database.
When the monitoring module receives a message which comprises the name of the interface device operated in the INTF _ TABLE TABLE and the corresponding operation SET when the Loopback0 is added into the Vrf1, the monitoring module modifies the Vrf information in the NTP _ SOURCR into { "Vrf _ name": vrf1"} and resets the NTP service.
When the Loopback0 is moved out of the Vrf1, the monitoring module receives a message, the message includes the interface device name operated in the INTF _ TABLE TABLE and the corresponding operation SET, modifies the Vrf information in the NTP _ SOURCR to { "Vrf _ name": global "}, and resets the NTP service.
When Vrf1 is deleted, the monitoring module receives a message of a VRF table, the message comprises the Vrf name operated in the VRF table and the corresponding operation DEL, the Vrf where the current NTP is located is checked, if the current NTP is deleted Vrf, vrf information in NTP _ SOURCR is modified into { "Vrf _ name": global "}, and NTP service is reset.
In some embodiments, writing information related to configuring a network time synchronization tool to the first information table comprises:
writing said information related to configuring the network time synchronization tool to said first information table by command.
In a specific embodiment, a configuration issuing module deployed on a switch writes a SOURCE interface name or a SOURCE IP address of an NTP to be configured and vrf into a database NTP _ SOURCE table through a command or a corresponding configuration file, where the SOURCE interface and the SOURCE IP address can only be set to one type, and the interface supports any one or more of a management interface, a service interface, a portchannel interface, a vlan interface, and a loopback interface.
In some embodiments, the configuration issuing module is further configured to save the database to an operation configuration file of a network operating system of a server, and save the operation configuration file to a start configuration file of the network operating system.
In a specific embodiment, the configuration of ntp is maintained in running-config (running configuration file) of the network operating system through the configuration issuing module, and then running-config is saved in startup-config (starting configuration file) through a related command for executing configuration saving. Therefore, the system is ensured to be reinstalled, and after the system is restarted, the subsequent modules can automatically configure the ntp service according to the ntp part in the startup-config configuration.
