Description

Information processing method, related equipment and network system

Technical Field

The present application relates to the field of switching devices, and in particular, to a method for processing information, a related device, and a network system.

Background

In network architectures such as storage area networks (storage area network, SANs), computing nodes and storage nodes (collectively referred to as nodes) are typically connected by a switching network that includes a plurality of switching devices, thereby building a storage system. In actual use, each switching device typically needs to synchronize information about the computing node and the storage node so that one node can timely sense the state of the associated node to determine operation between the nodes, e.g., the computing node can sense whether the storage node is online or offline to establish or disconnect with the storage node.

With the increasing size of the service, the size of the nodes in the storage system is increasing, so is the information about the computing nodes and the storage nodes that needs to be stored by the switching devices in the storage system, which results in that the switching devices need to consume a large amount of resources to store the information about the computing nodes and the storage nodes, for example, a large amount of related entries need to be stored, and the storage resources of the switching devices are consumed greatly.

Disclosure of Invention

The application provides a network system to solve the problem that a great deal of storage resources are consumed by switching equipment in the current storage system to store information about computing nodes and storage nodes, so that the consumption of the storage resources is relatively large. The application also provides corresponding methods, apparatus, switching devices, computer-readable storage media, computer program products, and the like.

The first aspect of the present application provides a network system, where the network system includes a first switching device and a second switching device, where the network system corresponds to at least one partition set, each partition set includes at least one partition, each partition includes a plurality of nodes that allow mutual access, partitions included in different partition sets are different, and partitions in different partition sets are isolated from each other; the first switching equipment is used for sending a first message to the second switching equipment, the first message comprises information of a first node, and the first node is a node in a first partition set corresponding to the first switching equipment; the second switching device is configured to receive the first message, and update information of the first node in the second switching device according to the first message when the first node is related to a second partition set corresponding to the second switching device.

In a first aspect, each set of partitions includes one or more partitions. The partitions in different partition sets being isolated from each other means that the partitions in different partition sets are each independently managed. The first message may be sent as an independent data packet from the first switching device to the second switching device, or may be combined with information of other nodes except the first node into the same data packet, and then the first switching device sends the combined data packet to the second switching device. At this time, the second switching device may obtain the first message from the data packet obtained after the merging through a specific information identifier. There may be a plurality of ways of updating the information of the first node in the second switching device based on the first message. In one example, the second switching device has stored therein the historical version information of the first node, and then when the first node is related to the second partition set corresponding to the second switching device, the second switching device may replace the historical version information of the first node in the second switching device with the received information of the first node. In another example, if the information of the first node is not stored in the second switching device, when the first node is related to the second partition set corresponding to the second switching device, the second switching device stores the information of the first node for the first time, so as to update the information of the first node in the second switching device for the first time.

As can be seen from the foregoing, in the first aspect, each partition corresponding to the network system may be combined to obtain a partition set, where the partitions in different partition sets are isolated from each other, and the first switching device sends a first message including information of the first node to the second switching device, and when the first node is related to the second partition set corresponding to the second switching device, the second switching device receives the first message, and updates the information of the first node in the second switching device according to the first message. In this way, the second switching device does not need to store information of all nodes in the global, so that consumption of storage resources can be reduced.

In a possible implementation manner of the first aspect, the second switching device is further configured to: when the first node is not associated with the second set of partitions, the first message is not processed.

In this possible implementation, not processing the first message means not performing a corresponding operation based on the content of the first message, e.g. performing an update operation of the corresponding information, etc. In this way, when the first node is not related to the second partition set, the second switching device determines that the first message is not related to the second switching device, so that storage is not needed, and waste of storage resources in the second switching device can be reduced.

In a possible implementation manner of the first aspect, the second switching device stores a receiving identifier of the second partition set, and the information of the first node includes a sending identifier of a third partition set corresponding to the first node, where the third partition set belongs to the first partition set; the first node is related to the second partition set corresponding to the second switching device, and the receiving identification of the second partition set is matched with the sending identification of the third partition set.

In one example, a set of partitions may be uniquely identified using an identification parameter that serves as both a receiving identification and a transmitting identification. In another example, two identification parameters may be used by one partition set to represent the transmission identification and the reception identification respectively, where the values of the two identification parameters corresponding to one partition set are the same, and at this time, the reception identification and the transmission identification corresponding to one partition set are the same; or the two identification parameters corresponding to one partition set have different values, and at the moment, the receiving identification and the sending identification corresponding to one partition set are different, so that the transmission direction of the related message between the switching devices can be reflected through the receiving identification and the sending identification with different values.

In a possible implementation manner of the first aspect, the second partition set includes a plurality of partition sets, and the matching of the receiving identifier of the second partition set with the transmitting identifier of the third partition set includes: the received identification of at least one of the plurality of sets of partitions matches the transmitted identification of the third set of partitions.

In this possible implementation manner, a part of the partition sets in the second partition set may be related to the third partition set, or all of the partition sets in the second partition set may be related to the third partition set, which is not limited.

In a possible implementation manner of the first aspect, the second switching device is further configured to: receiving a configuration message sent by first switching equipment, wherein the configuration message comprises a sending identifier of a first partition set and first configuration information of the first partition set; when the sending identifier of the first partition set is matched with the receiving identifier of the second partition set, updating second configuration information of the second partition set according to the configuration information, wherein the second configuration information comprises the identifier of a partition corresponding to the second partition set and information of nodes included by the corresponding partition.

In this possible implementation manner, the second configuration information is generally larger in data size and can be dynamically adjusted by the user according to the situation, and if configuration deployment is performed for each switching device one by one, the labor cost and the time cost are higher. In one scenario, when the first switching device is a reflector, configuration information may be sent to a plurality of reflector clients connected, thereby enabling efficient updating of the respective configuration information of the plurality of reflector clients.

In a possible implementation manner of the first aspect, the second switching device is further configured to: acquiring state change information of a second node associated with second switching equipment; and sending a second message to the first switching equipment, wherein the second message comprises state change information of the second node and a sending identifier of a fourth partition set corresponding to the second node, and the fourth partition set belongs to the second partition set.

In this possible implementation manner, the first switching device may determine, through the sending identifier in the second message, whether the fourth partition set corresponding to the second node is a partition set associated with the first switching device, so as to determine whether information update in the first switching device needs to be performed based on the second message, so that the data size of irrelevant data stored in the first switching device may be reduced, and waste of storage resources is reduced.

In a possible implementation manner of the first aspect, the first switching device is further configured to: generating a third message, wherein the third message comprises state change information of the second node and a sending identifier of the fourth partition set; and sending a third message to other switching devices which are connected with the first switching device except the second switching device.

As a person of ordinary skill in the art can know, with the development of technology and the appearance of new scenes, the technical solutions provided in the embodiments of the present application are applicable to similar technical problems.

In the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of the following" or similar expressions thereof, means any combination of these items, including any combination of single or plural items. The terms first, second and the like in the description and in the claims of the present application and in the above-described figures, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the application provides a network system to solve the problem that a great deal of storage resources are consumed by switching equipment in the current storage system to store configuration information about computing nodes and storage nodes, so that the consumption of the storage resources is large. Corresponding methods, switching devices, computer-readable storage media, computer program products, and the like are also provided by embodiments of the present application.

The network system includes a plurality of switching devices, and one or more of the switching devices in the network system may be connected to a node.

The number of nodes associated with the network system is not limited herein, and the number of nodes associated with the network system may vary with time. Functionally, any node in the embodiments of the present application may be a computing node, or a storage node. The computing node can access the storage node through the network system and acquire data in the storage node. The storage node is capable of storing data, and the storage node may be one storage unit or may be a storage array including a plurality of storage units. From a morphological aspect, the node in the embodiment of the present application may be a physical device, or may be a virtual device deployed on a physical device. For example, the computing node may be a physical device such as a physical server, a workstation, a mobile station, or other type of computer device, or may be a virtual device in the form of a Virtual Machine (VM) or a container (container). When a node is a virtual device, multiple nodes may be carried on the same physical device.

The network system and nodes may belong to a storage system. The storage system may be an ethernet storage system, for example, and the switching devices in the network system of the storage system are ethernet switching devices.

The storage system may comprise one or more data centers, each capable of performing a respective data storage operation. If the number of data centers of the storage system is plural, the plural data centers may form a dual-active data center, three or more multi-active data centers, a master/slave data center, or the like. Taking a dual-active data center as an example, in the dual-active data center, both data centers are in an active (active) state, and storage nodes of the two data centers are backed up.

The topology of the network formed by the switching devices in each data center is not limited herein. In one example, switching devices in the data center may include access switching devices (which may also be referred to as edge switching devices or leaf switching devices) connected to nodes and aggregation switching devices for connecting the access switching devices. Or, in another example, the data center may include an access switch, a convergence switch, and a core switch, the convergence switch for connecting the core switch and the access switch. The switching devices in each data center may enable data transfer between the corresponding compute node and the storage node of the respective data center.

As shown in fig. 1, an exemplary architecture of a storage system includes data centers 10 and 11, each of which includes a computing node and a storage node, with the computing node and the storage node communicating via a switching device.

Wherein the storage system is built based on a storage area network (storage area network, SAN). The data center 10 and the data center 11 form a dual active data center, and at this time, the storage nodes of the data center 10 and the storage nodes of the data center 11 are backed up with each other.

At least two switching devices in the storage system may belong to the network system provided in the embodiments of the present application. The network system provided in the embodiment of the present application is specifically described below with reference to fig. 2.

An exemplary architecture diagram of a network system is shown in fig. 2.

Wherein the network system 2 may comprise a first switching device 201 and a second switching device 202.

The first switching device 201 and the second switching device 202 included in the network system in the embodiment of the present application may be located in the same data center, or may be located in different data centers. The embodiments of the present application are not limited in this regard.

In this embodiment, the network system corresponds to at least one partition set, where each partition set includes at least one partition, each partition includes a plurality of nodes that allow mutual access, the partitions included in different partition sets are different, and the partitions in different partition sets are isolated from each other.

In the embodiment of the application, the nodes may be grouped by partition technology (partition), which is called partitioning. Where each partition may include multiple nodes, typically, computing nodes and storage nodes within the same partition may communicate with each other via a network system (referred to herein as a "mutual access"). A node may belong to multiple partitions and may communicate with other nodes belonging to the same partition. The specific arrangement manner of the partitions may be various, and the embodiments of the present application are not limited.

In the embodiment of the application, each partition set comprises at least one partition, the partitions contained in different partition sets are different, and the partitions in the different partition sets are isolated from each other.

Wherein, the partitions in different partition sets are isolated from each other, which means that the partitions in different partition sets are managed independently. When the information of the related partition sets is received, the switching equipment manages the information of the partition sets, and when the information of the irrelevant partition sets is received, the switching equipment does not need to manage, so that independent management of each partition set in the switching equipment is realized.

For example, an exemplary schematic diagram of a switching device and associated nodes is shown in fig. 3 a.

Wherein the various switching devices and nodes shown in fig. 3a may form a data center 30 and a data center 31. The data center 30 and the data center 31 form a dual active data center. Any computing node in data center 30 (e.g., computing node 301, computing node 302, or computing node 303) may access a storage node in data center 30 (e.g., storage node 321 or storage node 322) and may also access a storage node in data center 31 (e.g., storage node 323 or storage node 324) across data centers.

The individual nodes shown in fig. 3a form at least the following partitions:

partition a1: compute node 301, store node 321, store node 322;

partition a2: computing node 302, storage node 321, storage node 322;

partition a3: compute node 303, store node 321, store node 322;

partition a4: compute node 301, storage node 323, storage node 324;

partition a5: compute node 302, storage node 323, storage node 324;

partition a6: compute node 303, store node 323, store node 324.

The partition a1, the partition a2 and the partition a3 are all the relationship that corresponding nodes perform mutual access in the same data center, and the partition a4, the partition a5 and the partition a6 are all the relationship that corresponding nodes perform mutual access across the data center. Based on the categories of the mutual access relationship, a partition set A1 and a partition set A2 can be obtained, wherein:

Partition set A1: partition a1, partition a2, and partition a3;

partition set A2: partition a4, partition a5, and partition a6.

It can be seen that in some embodiments, in one partition set, the corresponding nodes are all in a relationship of mutual access in the same data center, or the corresponding nodes are all in a relationship of mutual access across the data center.

In the example shown in fig. 3a, switching device 313 may store only information related to partition set A1 and not information related to partition set A2.

Other sets of partitions may also be included in FIG. 3a, and are not listed here.

Another exemplary schematic of a switching device and associated nodes is shown in fig. 3 b.

The association between the individual nodes and the switching device is shown in fig. 3 b. In fig. 3b, each switching device and associated node belong to the same data center 32.

Based on the association between each node in fig. 3b and the switching device, each node shown in fig. 3b forms at least the following partitions:

partition b1: compute node 331, store node 341, store node 342;

partition b2: a compute node 332, a storage node 341, a storage node 342;

partition b3: compute node 333, store node 341, store node 342;

Partition b4: compute node 334, store node 343, store node 344;

partition b5: compute node 335, store node 343, store node 344;

partition b6: compute node 336, store node 343, store node 344.

Combining the above-mentioned partitions B1 to B6, a partition set B1 and a partition set B2 can be obtained, wherein:

partition set B1: partition b1, partition b2, and partition b3;

partition set B2: partition b4, partition b5, and partition b6.

The switching device 351 and the switching device 353 may store only the information related to the partition set B1 and not the information related to the partition set B2, and the switching device 354 and the switching device 355 may store only the information related to the partition set B2 and not the information related to the partition set B1, thereby saving storage resources in these switching devices.

Based on the network system in any of the above embodiments, an embodiment of the present application provides a method for processing information. As shown in fig. 4, the method includes steps 401-402.

Step 401, the first switching device sends a first message to the second switching device.

Illustratively, in the example shown in fig. 3a, the first switching device may be switching device 312 or switching device 315, and the second switching device may be switching device 311, switching device 313, switching device 314, or switching device 316. While in the example shown in fig. 3b the first switching device may be switching device 352 and the second switching device may be switching device 351, switching device 353, switching device 354 or switching device 355.

The first message includes information of a first node, where the first node is a node in a first partition set corresponding to the first switching device.

In the embodiment of the present application, the number of the first nodes is not limited herein. The first node may be part of or all of the nodes in the first partition set corresponding to the first switching device. The information of the first node may include information of the first node itself, and may further include association information of the corresponding node with other devices related thereto. Illustratively, the information of the first node may include at least one of the following information:

the method comprises the steps of internetworking protocol (Internet Protocol, IP) address of a first node, IP state of the first node, connection state between the first node and corresponding access switching equipment, IP address of the access switching equipment corresponding to the first node, interface information of the access switching equipment corresponding to the first node, and access state of the first node and corresponding first switching equipment.

The information of the first node may be received by the first switching device from other switching devices than the second switching device, which are connected to the first switching device, or may be information configured by the user on the first switching device, or may be received by the first switching device from other devices, such as a user terminal.

In one example, other switching devices (e.g., other access switching devices) connected to the first switching device, in addition to the second switching device, generate information of the first node and send the information to the first switching device upon detecting that the state of the first node changes (e.g., the first node newly accesses the corresponding switching device and establishes a connection or changes from a connected state to a disconnected state).

In another example, it may be information that the user configures the first node in the first switching device.

In this embodiment of the present application, the first message may be sent as an independent data packet from the first switching device to the second switching device, or may be combined with information of other nodes except the first node into the same data packet, and then the first switching device sends the combined data packet to the second switching device. At this time, the second switching device may obtain the first message from the data packet obtained after the merging through a specific information identifier.

Step 402, the second switching device receives the first message, and updates information of the first node in the second switching device according to the first message when the first node is related to the second partition set corresponding to the second switching device.

In the embodiment of the application, whether the first message is related to the second partition set corresponding to the second switching device or not may be determined based on the specified identifier in the first message (for example, the sending identifier corresponding to the first message) and the specified identifier in the second switching device (for example, the receiving identifier in the second switching device). The setting mode of the specified identifier can be various. In one example, a set of partitions may be uniquely identified using an identification parameter that serves as both a receiving identification and a transmitting identification. In another example, two identification parameters may be used by one partition set to represent the transmission identification and the reception identification respectively, and the values of the two identification parameters corresponding to one partition set may be the same, where the reception identification and the transmission identification corresponding to one partition set are the same; alternatively, the values of the two identification parameters corresponding to one partition set may be different, and at this time, the receiving identification and the transmitting identification corresponding to one partition set are different. At this time, if the transmission identifier in the first message matches the receiving identifier in the second switching device, it is determined that the first message is related to the second partition set corresponding to the second switching device.

There may be a plurality of ways of updating the information of the first node in the second switching device based on the first message.

In one example, the second switching device has stored therein the historical version information of the first node, and then when the first node is related to the second partition set corresponding to the second switching device, the second switching device may replace the historical version information of the first node in the second switching device with the received information of the first node.

In another example, if the information of the first node is not stored in the second switching device, the second switching device may store the information of the first node for the first time when the first node is related to the second partition set corresponding to the second switching device, so as to update the information of the first node in the second switching device for the first time. The information of the second switching device that does not store the first node may be information that only stores the identifier of the first node (such as the name of the first node), but does not store information of the first node, such as an IP address, a connection state with the corresponding switching device, or any information that does not store the first node.

In this embodiment, each partition corresponding to the network system may be combined to obtain a partition set, where the partitions in different partition sets are isolated from each other, and the first switching device may send a first message including information of the first node to the second switching device, where the second switching device may receive the first message, and update the information of the first node in the second switching device according to the first message when the first node is related to the second partition set corresponding to the second switching device. In this way, the second switching device does not need to store information of all nodes in the global, so that consumption of storage resources can be reduced.

In some embodiments, the second switching device does not process the first message when the first node is not associated with the second set of partitions.

Wherein not processing the first message means not performing a corresponding operation based on the content of the first message, e.g. performing an update operation of the corresponding information, etc. In this way, the second switching device does not need to store the first message when the first node is not related to the second partition set, so that the waste of storage resources in the second switching device can be reduced.

In some embodiments, the second switching device stores a receiving identifier of a second partition set, the information of the first node includes a sending identifier of a third partition set corresponding to the first node, the third partition set belongs to the first partition set, and the first node is related to the second partition set corresponding to the second switching device, where the first node includes:

the receiving identity of the second set of partitions matches the sending identity of the third set of partitions.

In the embodiment of the application, for any partition set, the partition set corresponds to a receiving identifier and a sending identifier. The sending identifier is used for marking when the switching equipment sends the information related to the partition set. The receiving identifier is used for matching the receiving identifier with the received message when the switching device receives the message, so as to determine whether the received message is related to the partition set corresponding to the switching device.

In some embodiments, the second set of partitions includes a plurality of sets of partitions, the second set of partitions having a receiving identification that matches a transmitting identification of the third set of partitions including:

the received identification of at least one of the plurality of sets of partitions matches the transmitted identification of the third set of partitions.

It may be seen that, in the embodiment of the present application, a part of the partition sets in the second partition set may be related to the third partition set, or all of the partition sets in the second partition set may be related to the third partition set, which is not limited in the embodiment of the present application.

If only the receiving identifiers of the partial partition sets in the plurality of partition sets are matched with the sending identifiers of the third partition set, updating the information of the first node in the second switching device according to the first message may include:

and updating the information of the node corresponding to the successfully matched receiving identifier in the second switching equipment according to the information corresponding to the successfully matched transmitting identifier in the first message.

In some embodiments, the first switching device and the second switching device may further perform corresponding information interaction based on the related configuration information of the partition set, so as to achieve data synchronization of the related configuration information in each switching device.

The following describes a scheme for performing corresponding information interaction between the first switching device and the second switching device based on the relevant configuration information of the partition set.

The second switching device may have second configuration information for the second set of partitions stored therein. The second configuration information may include an identification of a partition corresponding to the second partition set, and information of a node included in the corresponding partition. In this way, the second switching device may determine which partitions are associated with the second set of partitions and which nodes are associated with the second set of partitions based on the second configuration information.

The first acquisition and storage of the second configuration information by the second switching device may be regarded as a first update of the second configuration information by the second switching device. This first update is typically prior to steps 401-402 described above.

It can be seen that there is no timing limitation between the step of updating the second configuration information and the above steps 401-402.

The specific obtaining manner of the second configuration information may be various. The following are examples.

1. In one embodiment, the second configuration information may be user-configurable on the second switching device.

2. In one embodiment, the second configuration information is received by the second switching device from another device, such as a client terminal.

3. In one embodiment, the second configuration information is obtained by the second switching device from the first switching device.

The scheme of the second switching device acquiring the second configuration information from the first switching device is specifically described below.

As shown in fig. 5, a method for processing information in an embodiment of the present application is provided. The method comprises steps 501-503.

Step 501, the first switching device sends a configuration message to the second switching device.

The configuration message includes a transmission identification of the first set of partitions and first configuration information of the first set of partitions.

In this embodiment of the present application, the user may input the configuration information in the first switching device, or may also transmit the configuration information to the first switching device through other devices, such as a user terminal.

In some examples, the first switching device may be a convergence switching device or a core switching device and the second switching device may be an access switching device.

Step 502, the second switching device receives the configuration message sent by the first switching device.

Step 503, when the transmission identifier of the first partition set matches with the receiving identifier of the second partition set, the second switching device updates the second configuration information of the second partition set according to the configuration message.

The second configuration information includes an identification of a partition corresponding to the second partition set, and information of a node included in the corresponding partition.

In this embodiment of the present application, the receiving identifier of the second partition set may be stored in the second switching device in advance, so that the second switching device identifies, according to the sending identifier in the received message, whether the received message is related to the second partition set. The receiving identifier of the second partition set stored in advance in the second switching device may be manually configured on the second switching device, or may be received by the second switching device from another device such as a client terminal.

In addition, in some examples, the first switching device and the second switching device may also have respective corresponding switching device configuration information stored in advance.

The switching device configuration information may include an IP address of the switching device, a local port address of a transmission control protocol (Transmission Control Protocol, TCP), and device role information. The device role information is used to indicate that the corresponding switching device is a switching device, a reflector (reflector), or a reflector client (reflector client) in the single switching device network.

The second switching device may match the transmission identifier of the first partition set with the reception identifier of the second partition set after receiving the configuration information sent by the first switching device. In some examples, the first set of partitions may include multiple sets of partitions, and thus, there may be multiple transmit identifications in the first set of partitions. At this time, at least one sending identifier in the first partition set is matched with the receiving identifier of the second partition set, and the second switching device may update the second configuration information of the second partition set according to the information corresponding to the sending identifier successfully matched in the configuration information.

In some examples, when the transmission identity of the first set of partitions does not match the reception identity of the second set of partitions, the second switching device does not process the configuration message, i.e., does not perform a corresponding operation according to the content of the configuration information.

The configuration information and the second configuration information of the second switching device are described below with a specific example.

In an example, the basic information of each corresponding partition set may be configured in the first switching device and the second switching device in advance, where the basic information may include a transmission identifier and a reception identifier of the corresponding partition set, and may further include at least one of a name and description information of the corresponding partition set.

In addition, the first switching device may obtain first configuration information, where the first configuration information may include an identifier of a partition corresponding to the first partition set, and information of a node included in the partition corresponding to the first partition set.

The specific form of the first configuration information may be various, and is not limited herein. The first configuration information may be stored, for example, by one or more entries.

For example, the first configuration information may include a plurality of sets of data, and each set of data stores different information through a corresponding data structure.

In one example, the first switching device may store, through the data structure 1, basic information of any partition set in the first partition set, an identifier of a partition corresponding to the partition set, and an identifier of a node included in the partition corresponding to the partition set.

One way of setting the data structure 1 is as in table 1:

table 1: one way of setting the data structure 1

/>

Furthermore, the first switching device may store the association of each partition with a node through the data structure 2. One way of setting the data structure 2 is as in table 2:

table 2: one way of setting the data structure 2

When each partition adds a node, information of the corresponding node is added in the corresponding data structure 2; when each partition deletes a node, the information of the corresponding node is deleted in the corresponding data structure 2.

In the second switching device, the storage manner of the second configuration information of the second partition set may refer to the storage manner in the foregoing tables 1-2, which is not described herein again.

In this embodiment of the present application, the second configuration information is generally larger in data size and may be dynamically adjusted by the user according to the situation, and if configuration deployment is performed for each switching device, the labor cost and the time cost are higher. In one scenario, when the first switching device is a reflector, configuration information may be sent to a plurality of reflector clients connected, thereby enabling efficient updating of the respective configuration information of the plurality of reflector clients.

In some embodiments, corresponding information interaction can be performed between the first switching device and the second switching device based on the state change information of the node, so as to realize data synchronization of the related state change information in each switching device.

The following describes a scheme for performing corresponding information interaction between the first switching device and the second switching device based on the state change information of the node.

As shown in fig. 6, in some embodiments, the method may include:

in step 601, the second switching device obtains state change information of a second node associated with the second switching device.

Step 602, the second switching device sends a second message to the first switching device.

The second message includes state change information of the second node and a transmission identifier of a fourth partition set corresponding to the second node, where the fourth partition set belongs to the second partition set.

The state change information may include change information of an association state of the second node with the second switching device, the association state may be described by a state of the second node, the state becomes active, and indicates that the second node first accesses the second switching device or changes from a disconnected state to re-access the second switching device; or, the state is changed from active to inactive, and the second node and the second switching device are instructed to change from the connected state to the disconnected state.

The second switching device may obtain the state change information of the associated second node by monitoring the change condition of the relevant interface of the second node, and may also receive the state change information sent by the second node. After the second switching device obtains the state change information of the second node associated with the second switching device, the state change information and the sending identifier of the fourth partition set corresponding to the second node may be sent to the first switching device, so that the state change information of the second node may be notified to the first switching device by the second switching device, and the sending identifier of the fourth partition set associated with the second node may be notified, where the sending identifier of the fourth partition set corresponding to the second node may enable the receiving party to identify the fourth partition set associated with the second message.

In some examples, the second switching device may further query information of a partition to which the second node belongs after acquiring the state change information of the associated second node. If, in the partition to which the second node belongs, other nodes than the second node are connected to the second switching device, the second switching device may further send status change information of the second node to the other nodes, so that the other nodes determine subsequent information interaction operations based on the received status change information.

In some embodiments, the method further comprises:

step 603, the first switching device receives the second message.

Step 604, when the transmission identifier of the fourth partition set matches with the reception identifier of the first partition set, the first switching device updates the information of the second node in the first switching device according to the state change information of the second node and the transmission identifier of the fourth partition set.

In this way, the first switching device can determine the fourth partition set associated with the second node in the second message through the sending identifier in the second message, so that it can determine whether the fourth partition set is the partition set associated with the first switching device, and further determine whether the information update in the first switching device needs to be performed based on the second message, so that the data volume of irrelevant data stored in the first switching device can be reduced, and the waste of storage resources can be reduced.

In some embodiments, the method further comprises:

step 605, the first switching device generates a third message.

The third message includes state change information of the second node and a transmission identification of the fourth partition set.

Step 606, the first switching device sends a third message to other switching devices that are connected to the first switching device, except the second switching device.

Before the first switching device sends the third message, other switching devices connected with the first switching device except the second switching device can be determined through source removal operation, so that the third message is sent to the other switching devices connected with the first switching device except the second switching device, and corresponding other switching devices can perform corresponding processing according to the third message. For example, a certain other switching device may determine whether the sending identifier carried in the third message is matched with the receiving identifier of the partition set corresponding to the other switching device, and if so, update the information of the relevant node in the other switching device according to the third message, thereby implementing data synchronization of the state change information of the relevant node between each relevant switching device in the network system through the first switching device.

The timing relationship between steps 601-606 and steps 401-402 is not limited herein.

In the above embodiment, the mechanism of message interaction for establishing a connection between the first switching device and the second switching device may be based on a conventional mechanism, or may be adjusted based on the related content of the above embodiment on the conventional mechanism. In some examples, the types of messages transmitted between the first switching device and the second switching device include: OPEN, UPDATE, NOTIFICATION, KEEPALIVE. Wherein the UPDATE message may be used to send the first message, the second message, and the third message described above.

An exemplary message format for an UPDATE message is described as shown in table 3.

Table 3: an exemplary message format for an UPDATE message

Wherein, TLV refers to a type-length-value (tag-length-value). Only a portion of an example of an UPDATE message is shown in table 3, and not all message types of the UPDATE message are included.

The switching device may generate the content of a message based on the message format shown in table 4, which may be an UPDATE message of message type 11 or message type 12 in table 3, when it notifies other switching devices that the relevant partition configuration information is newly added, modified or deleted.

Table 4: an exemplary message format for messages relating to partition configuration information

The switching device, upon advertising the state change information of the relevant node to the other switching device, may generate the content of the message based on the message format shown in table 5, which may be an UPDATE message of message type 13 or message type 14 in table 3.

Table 5: an exemplary message format for a message regarding state change information

In some embodiments, the first switching device is a first reflector, the second switching device is a reflector client, and the network system further includes a third switching device, the third switching device is a second reflector, the first reflector and the second reflector corresponding to different sets of partitions.

The reflector can be connected with one or more reflector clients and can acquire information sent by each connected reflector client, and then send the information to other reflector clients except the source side so as to realize data synchronization among the switching devices. In this way, there is no need to establish a one-to-one connection between reflector clients to communicate information. Of course, in the embodiment of the present application, the connection relationship between the reflector clients is not limited, and based on some scene needs, the connection between the reflector clients connected to the same reflector may also be established. Generally, based on the reflector function, the aggregation switching device and/or the core switching device in the network system may be used as a reflector, and the corresponding access switching device may be used as a reflector client.

In the embodiment of the application, the network system comprises a first switching device serving as a first reflector and a third switching device serving as a second reflector, and the first reflector and the second reflector correspond to different partition sets. In this way, the related node information and the related configuration information of different partition sets can be respectively stored in different reflectors, so that the problem of overlarge load caused by the fact that a single reflector in a network system needs to store and process a large amount of partition set information is avoided, and load sharing in the network system is realized.

In some embodiments, the network system is a storage area network SAN, the plurality of nodes includes a computing node and a storage node, the network system includes a first subsystem and a second subsystem, the first subsystem includes a first switching device and a second switching device, the second subsystem includes a third switching device, and the storage nodes corresponding to the first subsystem and the second subsystem are backup to each other.

In the embodiment of the application, the SAN is a special high-speed network connecting the computing node and the storage node, and the computing node and the storage node of the SAN can form a special network for data storage. In this way, a data center may be formed through the SAN, thereby providing storage, delivery, and other processing of traffic data from the nodes for the actual application scenario.

With the continuous increase of service scale, in an actual application scenario, resources of a single data center are difficult to meet the service requirement, and in addition, data disaster recovery gradually becomes a common requirement due to the consideration of data security, service reliability and the like, so that a plurality of data centers can be established to support the service, and data backup is performed to realize the data disaster recovery.

Based on the above requirements, in some examples, multiple data centers may be established to afford related business processes, improve the processing capacity of the business data, and perform disaster recovery backup of the data.

For example, two data centers may form a dual active data center, i.e., both data centers are active, are peer-to-peer, are not master-slave, and may be simultaneously deploying traffic. The two data centers can be synchronized with each other according to a specified rule based on a service scene. Of course, in other examples, one data center, three data centers, or other numbers of data centers may be included in the storage system. The embodiments of the present application are not limited herein.

In this embodiment of the present application, the network system may include a first subsystem and a second subsystem, where storage nodes corresponding to the first subsystem and the second subsystem are backup to each other, and the reflector in the first subsystem includes a first switching device, and the reflector in the second subsystem includes a third switching device, so that the first subsystem and the second subsystem are respectively located in different data centers. And reflectors among different subsystems are different, so that the different subsystems bear the collection and transmission work of relevant configuration information and relevant node information among the switching equipment through the different reflectors respectively, equipment resources are reasonably distributed, and load sharing of the switching equipment among a plurality of data centers is realized.

An exemplary architecture diagram of a switching device and associated nodes is shown in fig. 7. The association between each switching device and a node is shown in fig. 7.

Based on the association relationship between each switching device and the node in fig. 7, each node shown in fig. 7 forms at least the following partitions:

partition c1: computing node 701, storage node 721, storage node 722;

partition c2: computing node 702, storage node 721, storage node 722;

partition c3: compute node 703, storage node 721, storage node 722;

partition c4: computing node 701, storage node 723, storage node 724;

partition c5: computing node 702, storage node 723, storage node 724;

partition c6: computing node 703, storage node 723, storage node 724;

partition c7: computing node 704, storage node 721, storage node 722;

partition c8: computing node 705, storage node 721, storage node 722;

partition c9: computing node 706, storage node 721, storage node 722;

partition c10: computing node 704, storage node 723, storage node 724;

partition c11: computing node 705, storage node 723, storage node 724;

partition c12: computing node 706, storage node 723, storage node 724.

From partitions C1-C12, a set of partitions C1-C4 can be obtained, wherein:

partition set C1: partition c1, partition c2, and partition c3;

partition set C2: partition c4, partition c5, and partition c6;

partition set C3: partition c7, partition c8, and partition c9;

partition set C4: partition c10, partition c11, and partition c12.

In the example shown in fig. 7, information interaction is achieved between the data center 70 and the data center 71 through a dual active network to achieve information synchronization between the first subsystem and the second subsystem. Specifically, the aggregation switch 712, the first switch 713 of the first subsystem, and the third switch 716, and the aggregation switch 717 of the second subsystem are all connected to a dual active network to realize data transmission across the data center. One or more switching devices may be included in the dual active network.

In fig. 7, the switching devices associated with the respective sets of partitions are identified. In the example shown in fig. 7, two reflectors may be associated with each partition set, specifically, the reflector associated with the partition set C1 is the aggregation switch 712 and the first switch 713, the reflector associated with the partition set C2 is the first switch 713 and the third switch 716, the reflector associated with the partition set C3 is the aggregation switch 712 and the aggregation switch 717, and the reflector associated with the partition set C4 is the third switch 716 and the aggregation switch 717. In this way, the disaster recovery of data can be realized for each partition set, disaster recovery backup between the data center 70 and the data center 71 is realized, and the problem that related node mutual access data of the corresponding partition set cannot be transmitted due to single reflector faults is avoided, so that the reliability of the system is improved.

However, as the number of reflectors increases, in the conventional scheme, information of related nodes and related configurations stored in each switching device increases multiple times, thereby requiring a lot of storage resources.

In this example, each switching device only needs to store the information of the relevant nodes and the relevant configuration of the relevant partition set, so that the corresponding operation needs can be met, the storage of a large amount of irrelevant data is reduced, and the waste of storage resources is reduced.

In the example shown in fig. 7, the number of individual reflectors and the set of reflector client-related partitions are equal, and thus load sharing between individual switching devices can be achieved.

Furthermore, in this example, the first switching device only needs to store the relevant node information and the relevant configuration information of the partition set C1 and the partition set C2, and does not need to store all the global partitions, that is, all the node information and the configuration information of the partitions C1 to C12, so that the consumption of storage resources is greatly reduced compared with the conventional scheme.

Having described the method of processing information in various aspects, embodiments of the present application will now be described with reference to the accompanying drawings.
