Technical Field

Background
In existing mechanisms that implement session maintenance based on a load balancer (i.e., ensure that multiple associated requests will be handled by the same server), when a client initial request reaches the load balancer, the load balancer typically selects an appropriate server and forwards the request based on the capabilities and load of the servers in the cluster. The server can process the request message and return a response message to the client, and usually takes the identifier of the server as a Session identifier (Session ID), writes the response message and returns the response message to the client; when the client sends the request message again, the client carries the session identifier, and the load balancer sends the application request to the server which is distributed previously through inquiring the mapping relation, so that session maintenance is realized.
Because the identifier of the server is used as the session identifier, when load (i.e., session state and context content) needs to be migrated, load migration often needs to be performed in units of servers, and flexible load migration cannot be achieved to achieve load balancing, thereby affecting information processing efficiency.

It should be noted that the load balancing server 104, the identifier distribution server 106, and the information processing servers 107 and 108 may be located on the same server.
With continued reference to FIG. 2, a timing diagram for one embodiment of an information handling system according to the present application is shown.
The information processing system in the embodiment may include an identifier distribution server, a load balancing server, and an information processing server cluster; the identification distribution server is used for distributing at least one segment identification for each information processing server in the information processing server cluster, sending the distributed at least one segment identification to the information processing server, generating a relationship list based on the corresponding relationship between each information processing server in the information processing server cluster and the segment identification of each information processing server, and sending the relationship list to the load balancing server; the load balancing server is used for receiving request information sent by the client, determining whether the request information has a segment identifier, if the request information does not have the segment identifier, selecting an information processing server from the information processing server cluster as a target information processing server, and sending the request information to the target information processing server; and the target information processing server is used for processing the request information, generating response information containing the segment identifier of the target information processing server, and returning the response information to the client so that the client sends the request information containing the segment identifier of the target information processing server.
As shown in fig. 2, in step 201, the identifier assigning server is configured to assign, to each information processing server in the information processing server cluster, at least one segment identifier to the information processing server, and send the assigned at least one segment identifier to the information processing server.
In the present embodiment, an identifier assignment server (e.g., identifier assignment server 106 shown in fig. 1) may assign at least one segment identifier to each information processing server (e.g., information processing servers 107, 108 shown in fig. 1) in the information processing server cluster to which it is communicatively connected by various methods. Such as random assignment or segment identification assignment based on configuration information of the information handling server. As an example, the larger the memory space of the information processing server or the higher the main frequency value of the processor, the more segment identifiers are allocated. And transmitting the assigned at least one segment identifier to a corresponding information processing server through a wired connection or a wireless connection. The segment identifier may be used to indicate an information processing server in the information processing server cluster that processes the request information sent by the client (e.g., the user terminal 101, 102 shown in fig. 1). The segment identifier may be one of a number, a letter, a word, a symbol, or a combination of at least two of them.
In step 202, the identifier assigning server generates a relationship list based on the correspondence between each information processing server in the information processing server cluster and the segment identifier of each information processing server, and sends the relationship list to the load balancing server.
In the present embodiment, the identification assignment server may generate the relationship list based on the correspondence relationship of each information processing server and the segment identification assigned to each information processing server in step 201. And send the relationship list to a load balancing server (e.g., load balancing server 104 shown in fig. 1) communicatively coupled thereto via a wired connection or a wireless connection. The method for generating the relationship list is not limited in the present application, and for example, the relationship list is generated by storing an identifier of the information processing server (such as a name of the information processing server, an IP (Internet Protocol Address), and the like) and a corresponding segment identifier into a list.
In some optional implementation manners of this embodiment, the identifier allocation server may further be configured to modify and manage a corresponding relationship between each information processing server in the existing relationship list and the segment identifier, which may specifically refer to the embodiments shown in fig. 3, fig. 4, and fig. 5.
In step 203, the load balancing server is configured to receive request information sent by the client.
In this embodiment, the load balancing server may receive request information sent by the user using the client through a wired connection or a wireless connection. The request information may be information related to a service provided by the information processing server, for example, request information for accessing a certain website.
In step 204, the load balancing server determines whether the request message contains a segment identifier, and selects an information processing server from the information processing server cluster as a target information processing server if the segment identifier does not exist.
In this embodiment, the load balancing server may first look at the content of the request information to determine if there is a segment identification therein. Wherein the segment identifier may be used to indicate an information processing server in the information processing server cluster that processes the request information. If the segment identifier does not exist, it can be said that the request information is the initial request information, that is, the information processing server has not processed the request information yet. The load balancing server may select an information processing server from the information processing server cluster as a target information processing server by various methods. For example, the load of each information processing server can be distributed evenly, so that the processing efficiency of the request information is improved.
In some optional implementation manners of this embodiment, if a segment identifier exists in the request information, the load balancing server may first select a segment identifier matching the segment identifier in the request information from the relationship list; then, taking the information processing server corresponding to the selected segment identifier as a target information processing server; and finally, sending the request information to a target information processing server.
In step 205, the load balancing server sends the request information to the target information processing server.
In this embodiment, based on the target information processing server determined in step 204, the load balancing server may forward the request information received in step 203 to the target information processing server in communication connection therewith, so that the target information processing server processes the request information.
In step 206, the target information processing server is configured to process the request information and generate response information including the segment identifier of the target information processing server.
In this embodiment, after receiving at least one segment identifier allocated to the target information processing server sent by the identifier allocation server, the target information processing server may allocate, to each segment identifier, a session identifier list containing at least one session identifier corresponding to the segment identifier. The session identifier may be a session identifier commonly used in the prior art, and is mainly used for associating the browser on the client with the related session data and information on the target information processing server. The number of session identifiers corresponding to each segment identifier may be the same or different.
In this embodiment, after receiving the request information from the client forwarded by the load balancing server, the target information processing server may allocate an unoccupied session identifier to the request information according to a current internal load condition, that is, an occupation condition of the session identifier. The request information is then processed and response information is generated that contains at least a segment identification corresponding to the session identification assigned to the request information. It is to be understood that, since the request information is the initial request information, the generated response information may be information containing only the segment identification of the target information processing server, or information further containing the session identification corresponding to the segment identification. As an example, the response information may include not only the segment identifier and the session identifier, but also information related to the request information.
In some optional implementations of this embodiment, if the segment identifier exists in the request information, it may be stated that the request information is not the initial request information. At this time, if the request information further includes a session identifier, the target information processing server may determine whether the session identifier in the request information exists locally (i.e., whether the session identifier identical to the session identifier in the request information exists in the session identifier list corresponding to the segment identifier in the request information in the target information processing server). In response to the absence of the session identifier in the request information, it can be said that the previous request information is likely to be processed by another information processing server, and then the segment identifier therein (the segment identifier in the request information) is migrated to the target information processing server. At this time, the target information processing server may select one session identifier from the session identifier list corresponding to the segment identifier in the request information, process the request information, and generate response information including the segment identifier in the request information and the session identifier corresponding to the segment identifier. In response to the session identification existing in the request information, it can be said that the previous request information was processed by the target information processing server. At this time, the target information processing server may process the request information based on the session identifier, and generate response information including the segment identifier and the session identifier in the request information, in association with the request information.
In step 207, the target information processing server returns response information to the client.
In this embodiment, the target information processing server may return the response information generated in step 206 to the client that sent the request information, so that the client subsequently sends the request information containing at least the segment identifier of the target information processing server. It is to be understood that, when the segment identifier and the session identifier corresponding to the segment identifier are included in the response information, the segment identifier and the session identifier in the response information may be included in the request information.
In the information processing system provided by the embodiment of the application, at least one segment identifier is allocated to an information processing server in an information processing server cluster through an identifier allocation server, and a relationship list generated based on the corresponding relationship between each information processing server and the segment identifier is sent to a load balancing server. And then after receiving the request information sent by the client, the load balancing server determines a target information processing server by determining whether the request information has the segment identifier, and sends the request information to the target information processing server. Finally, the target information processing server processes the request information and generates response information containing the segment identifier of the target information processing server. Since one information processing server can correspond to a plurality of segment identifiers, the load balancing server can perform load balancing distribution management on each information processing server based on the segment identifiers. The identifier distribution server may manage the correspondence between each information processing server and the segment identifier based on the segment identifier. This facilitates flexible management of each information processing server, thereby improving information processing efficiency.
With further reference to FIG. 3, a timing diagram of another embodiment of an information handling system provided herein is shown.
In step 301, the identifier assigning server detects an instruction for instructing assignment of segment identifiers, and assigns at least one segment identifier to the newly added information processing server indicated by the instruction.
In this embodiment, the instruction for instructing to allocate the segment identifier may be triggered by the newly added information processing server actively sending information to the identifier allocation server after joining the information processing server cluster. Or may be triggered by the identification of the allocation server upon detection of a new information processing server in the information processing server cluster. The instruction may include an identifier of an information processing server newly added to the information processing server cluster. The identifier assignment server may assign at least one segment identifier to the newly added information processing server indicated by the identifier in the instruction after detecting the instruction. The allocation method can refer to the related description in the embodiment of fig. 2, and is not described herein again. It should be noted that the segment identifier allocated to the newly added information processing server may be a segment identifier to be allocated stored in the identifier allocation server, or may be transferred from the segment identifiers of other information processing servers in the information processing server cluster (see the relevant description in fig. 5 for a specific process).
In step 302, the identifier assignment server sends the assigned at least one segment identifier to the newly added information processing server.
In this embodiment, the identification assignment server may transmit the segment identification assigned to the newly added information processing server communicatively connected thereto. When processing the request information, the newly added information processing server can generate response information containing the segment identifier or containing the segment identifier and the session identifier corresponding to the segment identifier.
In step 303, the identifier assignment server sends the correspondence between the newly added information processing server and the segment identifier of the newly added information processing server to the load balancing server.
In this embodiment, the identifier assignment server may send the correspondence between the newly added information processing server and the segment identifier of the newly added information processing server to the load balancing server, so that the load balancing server updates the relationship list.
The information processing system provided in this embodiment may allocate segment identifiers to newly added information processing servers in the information processing server cluster. Therefore, when the load balancing server receives the initial request information sent by the client, the newly added information processing server can be used as a new resource, and the balanced distribution of the load is realized. Meanwhile, when the load balancing server receives the request information containing the segment identifier of the newly added information processing server, the request information can be forwarded to the newly added information processing server.
With continued reference to FIG. 4, a timing diagram of yet another embodiment of an information handling system provided herein is shown.
In step 401, the identifier assigning server detects an instruction for instructing deletion of the segment identifier, determines whether the information processing server to be deleted indicated by the instruction currently has the request information to be processed, and if not, takes the segment identifier of the information processing server to be deleted as the segment identifier to be assigned.
In this embodiment, the instruction for instructing to delete the segment identifier may also be triggered by the information processing server to be deleted in the information processing server cluster actively sending information to the identifier assigning server. Or may be manually triggered. The instruction may include an identifier of an information processing server to be deleted in the information processing server cluster. After detecting the instruction, the identifier allocation server may obtain the operating state of the information processing server to be deleted, which is indicated by the identifier in the instruction, so as to determine whether there is currently pending or pending request information therein. For example, each session identifier list in the information processing server to be deleted has no session identifier in an occupied state, which indicates that no request information processing is currently performed.
In this embodiment, if there is no request information to be processed or being processed in the information processing server to be deleted, the identification assignment server may assign the segment identification of the information processing server to be deleted to another information processing server as the segment identification to be assigned.
Alternatively, if there is request information to be processed or being processed in the information processing server to be deleted, information related to the request information (segment identifier, session identifier, context content, and the like) needs to be migrated at this time (for a specific process, see the related description in the embodiment of fig. 5).
In step 402, the identity assignment server sends feedback information to the information processing server to be deleted.
In this embodiment, the identifier allocation server may further send feedback information to the information processing server or the client to be deleted, which triggers the instruction, so that it is determined that the deletion task of the information processing server to be deleted can be performed. The feedback information may include, but is not limited to, "the segment identification of the information processing server has been deleted".
In step 403, the identity distribution server sends deletion information to the load balancing server.
In this embodiment, the identifier allocating server may send deletion information to the load balancing server, so that the load balancing server deletes the correspondence between the information processing server to be deleted and the segment identifier to be allocated in the relationship list. The deletion information may include (but is not limited to) an identification of the information processing server to be deleted or an identification of the segment to be assigned.
The information processing system provided in this embodiment may redistribute the segment identifier of the information processing server to be deleted in the information processing server cluster. In this way, when the load balancing server receives the initial request information sent by the client, the information processing server to be deleted can be removed from the available resources.
With continued reference to FIG. 5, a timing diagram of yet another embodiment of an information handling system provided herein is shown.
In step 501, the identifier allocating server detects an instruction for indicating a migration segment identifier, selects at least one identifier from identifiers indicating information processing servers in the information processing server cluster except for the information processing server to be migrated, and uses the information processing server indicated by the selected at least one identifier as the information processing server to be migrated.
In this embodiment, the trigger condition of the instruction for indicating the migration segment identifier may include: the load of each information processing server is seriously unbalanced, there is an information processing server newly added or withdrawn or a failure occurs, and the like. The instruction may include a segment identifier to be migrated.
In this embodiment, after detecting the instruction, the identifier allocating server may select at least one identifier from identifiers indicating information processing servers in the information processing server cluster, except for the information processing server to be migrated, and use the information processing server indicated by the selected at least one identifier as the information processing server to be migrated. As an example, the identifier allocation server may be selected randomly, or may be selected according to the load condition of each current information processing server. The information processing server to be migrated identifies the corresponding information processing server before migration for the segment to be migrated. It can be understood that, when there are multiple segment identifiers to be migrated, the identifier allocation server may select multiple information processing servers to be migrated, and allocate the segment identifiers to be migrated to the information processing servers to be migrated uniformly or according to the load condition.
In step 502, the identifier assignment server sends the segment identifier to be migrated in the instruction to the information processing server to be migrated.
In this embodiment, the identifier allocation server may send the segment identifiers to be migrated in the instruction allocated to each information processing server to be migrated to the corresponding information processing servers to be migrated.
In step 503, the identifier allocating server sends the correspondence between the information processing server to be migrated and the segment identifier to be migrated to the information processing server to be migrated.
In this embodiment, the identifier allocation server may further send the correspondence between the information processing server to be migrated and the segment identifier to be migrated to the information processing server to be migrated, so that the information processing server to be migrated sends the session identifier list corresponding to the segment identifier to be migrated to the information processing server to be migrated. It should be noted that, in the case that the information processing server to be migrated stores the context content of the session alone, the information processing server to be migrated needs to send the context content related to each session identifier in the session identifier list to be migrated to the information processing server to be migrated. Therefore, when the information processing server to be migrated receives the request information containing the segment identifier to be migrated and the session identifier corresponding to the segment identifier, the request information is conveniently processed.
It is understood that load migration cannot be performed when the information processing server to be migrated fails, so the identification allocation server may not perform step 503. At this time, when receiving the request information, the information processing server to be migrated may re-allocate the session identifier corresponding to the segment identifier to be migrated to the information processing server to be migrated.
In step 504, the identifier distribution server sends the correspondence between the information processing server to be migrated and the segment identifier to be migrated to the load balancing server.
In this embodiment, the identifier allocating server may send the correspondence between each information processing server to be migrated and the segment identifier to be migrated allocated to each information processing server to be migrated to the load balancing server, so that the load balancing server updates the relationship list.
The information processing system provided by the embodiment can migrate the segment identifier. And when load migration is carried out, the segment identification can be used as a unit, so that the flexibility of load migration is improved. This is favorable to the balanced distribution of the load, thus has raised the information processing efficiency.

As an example, the method may further include: detecting an instruction for indicating a migration segmentation identifier, selecting at least one identifier from identifiers of information processing servers except an information processing server to be migrated in an information processing server cluster, taking the information processing server indicated by the selected at least one identifier as the information processing server to be migrated, and sending the segmentation identifier to be migrated in the instruction to the information processing server to be migrated, wherein the instruction comprises the segmentation identifier to be migrated, and the information processing server to be migrated is the corresponding information processing server before the migration of the segmentation identifier to be migrated; and sending the corresponding relation between the information processing server to be migrated and the segment identifier to be migrated to the load balancing server so that the load balancing server updates the relation list.
Optionally, before sending the correspondence between the information processing server to be migrated and the segment identifier to be migrated to the load balancing server, the method may further include: and sending the corresponding relation between the information processing server to be migrated and the segment identifier to be migrated to the information processing server to be migrated so that the information processing server to be migrated sends the session identifier list corresponding to the segment identifier to be migrated to the information processing server to be migrated.

And the load balancing server can carry out load balancing management on the information processing server according to the segment identification. Therefore, the flexibility of load migration is improved, the load is balanced and distributed, and the information processing efficiency is improved.
