Description

Distributed system, network processing method and device and electronic equipment

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a distributed system, a network processing method and apparatus, and an electronic device.

Background

In a cloud computing environment, cloud computing services are typically provided by a union of multiple servers. In order to meet the service access requirement under the scenarios of server automatic scaling, machine failure or version upgrade, a distributed cooperative service unit is usually arranged between a service provider (e.g., an application server) and a service caller (e.g., an application client), and is used as a registration center of a third party to provide address registration and address resolution functions for both parties.

Fig. 1 is a schematic diagram of a single distributed collaboration service unit in the prior art. As shown in fig. 1, the application server sends an address registration request to the distributed collaborative service unit, for example, stores the correspondence between the name address and the IP address in the distributed collaborative service unit to register the IP address; and when the application client accesses the application service, an address resolution request is sent to the distributed cooperative service unit according to the public name address of the application server so as to resolve the IP address corresponding to the name address, and then the application service is accessed according to the obtained IP address.

With the rapid development of business scale, the service capacity of a single distributed cooperative service unit cannot meet the ever-increasing address registration demand, and therefore, a plurality of distributed cooperative service units need to be deployed to form a distributed cooperative service unit group to improve the total service capacity.

Fig. 2 is a schematic diagram of setting up a plurality of distributed collaborative service units in the prior art. As shown in fig. 2, different distributed collaborative service units provide address registration services for different application servers, and when an application client accesses an application service, the application client first needs to find a distributed collaborative service unit that provides an address registration service for a corresponding application server, and then accesses the distributed service unit to perform address resolution. Therefore, a global routing table needs to be introduced to record the correspondence between the unit name of each distributed collaborative service unit and the access entry thereof. When the client end which carries out address registration sends an address registration request and when the client end which carries out address analysis sends an address analysis request, the access entrance of the distributed cooperative service unit which needs to be accessed is obtained by reading the global routing table.

In the process of implementing the invention, the inventor finds that the prior art has at least the following problems: in the prior art, a global routing table is stored in each address registration client and each address resolution client, and the global routing table needs to be maintained by all the clients together, so that the maintenance cost is high; meanwhile, the global routing table is stored in all the clients, so that the global routing table can only be static and cannot be updated in real time, and online migration of services cannot be supported.

In the prior art, a global routing table for recording the correspondence between the unit names of a plurality of distributed collaborative service units and the access entries thereof is stored in all clients (including an address registration client and an address resolution client), when a client sends a request (such as an address registration request, an address resolution request, and the like) related to an address service, the client obtains the access entry of a service unit to be accessed by reading the stored global routing table, and the global routing table needs to be maintained by all the clients together, so that the maintenance cost is very high; meanwhile, the global routing table can only be static and cannot support online migration of services.

Therefore, the present application proposes a network processing scheme, whose main principle is: an intermediate node is arranged between a client and a distributed cooperative service unit for providing relevant address service for the client, and the request sent by the client is routed through the intermediate node according to a global routing table, so that the global routing table is prevented from being stored in each client, the intermediate node replaces the client to maintain the global routing table, the maintenance cost of the global routing table is reduced, the global routing table can be dynamically updated, and the online migration of the service can be supported.

The above embodiments are illustrative of technical principles and exemplary application frameworks of the embodiments of the present invention, and specific technical solutions of the embodiments of the present invention are further described in detail below through a plurality of embodiments.

Example one

Fig. 3 is a system block diagram of an embodiment of a distributed system provided by the present invention. As shown in fig. 3, the distributed system provided in the embodiment of the present invention includes: a plurality of clients 31, a plurality of distributed collaborative service units 32 and at least one intermediate node 33.

The client 31 is a client for obtaining a service related to an address, and the distributed collaboration service unit 32 is configured to provide a service, such as a service related to an address, for each client 31. The intermediate node 33 is configured to receive a service request sent by the client 31, such as an analysis request, a registration request, a session request, an address subscription request, and the like, query the global routing table according to the service request, obtain a corresponding target distributed cooperative service unit 32 from the global routing table, and route the service request to the target distributed cooperative service unit 32.

In the embodiment of the present invention, the client 31 may be an address registration client (for example, a host in a cloud service product, or a server providing an application service, etc.) for obtaining an address registration service for a user, or an address resolution client (for example, a front-end machine in a cloud service product, or an application client accessing a server, etc.) for obtaining an address resolution service. When the client 31 generates a request for an address service and transmits the request to the intermediate node 33, the intermediate node 33 queries a global routing table for recording the correspondence relationship between the plurality of distributed cooperative service units 32 and the client 31 according to the request.

Specifically, after receiving the request related to the address service, the intermediate node 33 queries the global routing table according to the service unit information in the request, acquires the target distributed cooperative service unit 32 in the global routing table, and sends the request to the target distributed cooperative service unit 32, so that the target distributed cooperative service unit 32 provides the service related to the address to the client 31 that sent the request.

In the distributed system provided by the embodiment of the invention, the intermediate node is arranged between the client and the distributed cooperative service unit providing services for the client, so that the service request sent by the client is routed to the corresponding distributed cooperative service unit according to the global routing table, thereby avoiding storing the global routing table in each client and reducing the maintenance cost of the global routing table; meanwhile, the global routing table can be dynamically updated, so that online migration of services can be supported.

Example two

Fig. 4 is a system block diagram of another embodiment of a distributed system provided by the present invention. As shown in fig. 4, on the basis of the embodiment shown in fig. 3, in the distributed system provided in the embodiment of the present invention, the service request sent by the client 31 may carry user tenant information of a user tenant to which the request is directed. At this time, the global routing table also records the correspondence between the plurality of distributed collaborative service units 32 and the user tenant. As shown in table 1, which is an example of a global routing table in the embodiment of the present invention, a correspondence between tenant names of different user tenants and unit names of the distributed collaborative service units 32 is recorded, for example, tenants a and C correspond to the distributed collaborative service unit 1, tenant B corresponds to the distributed collaborative service unit 2, and tenant D corresponds to the distributed collaborative service unit 3.

TABLE 1

Tenant name	Name of unit
		A	1
B	2
		C	1
D	3

Specifically, after receiving the request related to the address service sent by the client 31, the intermediate node 33 queries the global routing table according to the user tenant information (tenant name) carried in the request, acquires the unit name of the distributed cooperative user unit 32 corresponding to the user tenant information in the global routing table, and sends the request to the distributed cooperative service unit 32, so that the corresponding distributed cooperative service unit 32 provides the address-related service to the client 31 that sends the request.

Further, the distributed system provided by the embodiment of the present invention may further include a data management center 41, where the data management center 41 is configured to store the global routing table.

In the embodiment of the present invention, a plurality of intermediate nodes 33 may be provided, and different intermediate nodes 33 may be responsible for processing requests related to address services sent by different clients 31. Therefore, the data management center 41 may be configured to store the global routing table to ensure global state consistency of the global routing table queried by all intermediate nodes 33. Each intermediate node 33 may read the global routing table from the data management center 41 during the process startup phase to perform the requested routing operation.

Further, the data management center 41 may be further configured to send the updated global routing table to the intermediate node 33 when the global routing table is updated. Specifically, each intermediate node 33 may subscribe to a change event of the global routing table at the data management center 41, and when the global routing table stored in the data management center 41 is updated, the data management center 41 sends the updated global routing table to the intermediate node 33 to support online migration of the address registered by the address registration client.

In this embodiment of the present invention, the client 31 includes: an address registration client for obtaining an address registration service and an address resolution client for obtaining an address resolution service, where the service request sent by the address registration client may include, but is not limited to: the address registration request, the address subscription request, and the lease maintenance request, and the service request sent by the address resolution client may include, but is not limited to: an address resolution request.

In the embodiment of the present invention, when performing the migration of the registration address, the global routing table stored in the intermediate node 33 or the data management center 41 may adopt a three-hop upgrade mechanism, that is, the global routing table is updated by three times of version upgrade. The embodiment shown in fig. 4 is described by taking the example where the global routing table is stored in the data management center 41. Specifically, the distributed cooperative service unit 32 recorded in the global routing table may include a registration unit for providing an address registration service and a resolution unit for providing an address resolution service. The intermediate node 33 may specifically be configured to send the address resolution request for the user tenant sent by the client terminal 31 to the resolution unit corresponding to the user tenant, and send the address registration request for the user tenant sent by the client terminal 31 to the registration unit corresponding to the user tenant. As shown in table 2a, a version one of another example of the global routing table in the embodiment of the present invention is a version one, in which user tenant information of different user tenants is recorded, for example, a tenant name, a corresponding relationship between a resolution unit name of a resolution unit and a registration unit name of a registration unit, and before performing registration address migration, in an initial version of the global routing table, the resolution unit is consistent with the registration unit, for example, tenants a and C correspond to the resolution unit 1 and the registration unit 1, and tenant B corresponds to the resolution unit 2 and the registration unit 2, and so on.

TABLE 2a

When a register address migration instruction for changing a distributed cooperative service unit corresponding to a user tenant from a source distributed cooperative service unit to a target distributed cooperative service unit is received, resolving units corresponding to the user tenant, recorded in a global routing table, are the source distributed cooperative service unit and the target distributed cooperative service unit, the priority of a return result of the source distributed cooperative service unit is higher than that of the target distributed cooperative service unit, and a register unit corresponding to the user tenant, recorded in the global routing table, is the source distributed cooperative service unit. That is, when the data management center 41 receives the register address migration instruction, the global routing table stored therein is changed from the above-described initial version to the first intermediate version shown in table 2b below. As shown in table 2b, as a second example version of the global routing table in the embodiment of the present invention, after receiving the register address migration instruction, the global routing table is changed to a first intermediate version, in the first intermediate version, the parsing unit corresponding to the user tenant is the source distributed collaborative service unit and the target distributed collaborative service unit, for example, the parsing unit corresponding to the tenant a is changed to the source distributed collaborative service unit 1 and the target distributed collaborative service unit 3, and the priority of the returned result of the source distributed collaborative service unit 1 is higher than that of the target distributed collaborative service unit 3 (that is, the response returned by the source distributed collaborative service unit 1 is preferentially fed back to the client 31 for the response returned by the source distributed collaborative service unit 1 and the target distributed collaborative service unit 3).

TABLE 2b

			C	1	1

In addition, when performing the registered address migration, the intermediate node 33 may also send a subscription change event notification to the relevant address registration client, where the subscription change event notification is used to trigger the address registration client to perform address registration again.

When the intermediate node 33 sends a subscription change event notification to the address registration client in the user tenant, the parsing units corresponding to the user tenant recorded in the global routing table are the target distributed cooperative service unit and the source distributed cooperative service unit, the priority of the returned result of the target distributed cooperative service unit is higher than that of the source distributed cooperative service unit, and the registration unit corresponding to the user tenant recorded in the global routing table is the target distributed cooperative service unit. That is, when the intermediate node 33 sends the subscription change event notification to the address registration client in the user tenant, the global routing table is changed from the above-described first intermediate version to a second intermediate version shown in table 2c below. As shown in table 2c, as a third version of another example of the global routing table in the embodiment of the present invention, when a subscription change event notification is sent, the global routing table is changed to a second intermediate version, in the second intermediate version, the parsing units corresponding to the user tenant are the source distributed collaborative service unit and the target distributed collaborative service unit, and the registration unit corresponding to the user tenant is the target distributed collaborative service unit. For example, the parsing unit corresponding to the tenant a is still the source distributed collaborative service unit 1 and the target distributed collaborative service unit 3, but the return result of the target distributed collaborative service unit 3 has higher priority than the return result of the source distributed collaborative service unit 1 (i.e., for the response returned by the source distributed collaborative service unit 1 and the target distributed collaborative service unit 3, the response returned by the target distributed collaborative service unit 3 is preferentially fed back to the client 31). And the registration unit corresponding to the tenant a is changed to the target distributed collaborative service unit 3.

TABLE 2c

Name of renter	Parsing unit names	Name of registered unit
			A	3/1	3
B	2	2
			C	1	1

When all address registration clients in the user tenant complete address registration again, the parsing unit and the registration unit which are recorded in the global routing table and correspond to the user tenant are both target distributed cooperative service units. That is, when all the address registration clients in the user tenant complete address registration again, the global routing table is changed from the second intermediate version to the final version shown in the following table 2 d. As shown in table 2d, as a version four of another example of the global routing table in the embodiment of the present invention, when all address registration clients complete address registration again, the global routing table is changed to a final version, and in the final version, both the parsing unit and the registering unit corresponding to the user tenant are target distributed cooperative service units. For example, the resolution unit corresponding to the tenant a is changed to the target distributed collaborative service unit 3. And at this point, completing the online migration of the registered address.

			C	1	1

Further, according to an embodiment of the present invention, the intermediate node 33 may manage access to the distributed collaborative service unit 32 by creating a finite state machine. For example, by creating a finite state machine for an access request from the client 31, the access requests for the same distributed collaborative service unit 32 can be aggregated by the finite state machine and then sent to the distributed collaborative service unit 32, so that the distributed collaborative service unit 32 can reduce the number of connections created for the access request from the intermediate node 33, and the access pressure of the distributed collaborative service unit 32 can be reduced.

In addition, according to the embodiment of the present invention, the correspondence between the consistent hash value of the distributed cooperative service unit 32 calculated according to the consistent hash algorithm and the plurality of distributed cooperative service units 32 may be recorded in the global routing table. For example, the intermediate node 33 may query the global routing table according to a hash value corresponding to a user tenant for which the request is intended, which is included in the request regarding the address service sent by the client 31, thereby obtaining the distributed collaborative service unit 32 corresponding to the user tenant, and send the request to the distributed collaborative service unit 32. In this case, the client 31 does not need to include user tenant information in the request on the address service, but only needs to include a hash value calculated according to a consistent hash algorithm, so that the intermediate node 33 can obtain the corresponding distributed cooperative service unit 32 from the hash value.

In the distributed system provided by the embodiment of the invention, the intermediate node is arranged between the client and the distributed cooperative service unit which provides the address-related service for the client, so that the request sent by the client is routed to the corresponding distributed cooperative service unit according to the global routing table, thereby avoiding storing the global routing table in each client and reducing the maintenance cost of the global routing table; the data management center is arranged to store the global routing table so as to further ensure the global state consistency of the global routing table and ensure that the global routing table can be dynamically updated, thereby supporting the online migration of the registered address; meanwhile, by introducing the user tenant information, the intermediate node queries the corresponding distributed cooperative service unit according to the user tenant information, so that the service is decoupled from the distributed cooperative service unit information, and the service access cost is reduced.

S604, sending the request to the distributed collaborative service unit corresponding to the user tenant, so that the distributed collaborative service unit provides the address-related service to the client.

In the embodiment of the present invention, the distributed collaborative service unit recorded in the global routing table includes a registration unit for providing an address registration service and a resolution unit for providing an address resolution service. Specifically, the intermediate node may send an address resolution request sent by the client for the user tenant to a resolution unit corresponding to the user tenant, and send an address registration request sent by the client for the user tenant to a registration unit corresponding to the user tenant.

Further, according to embodiments of the invention, the intermediate node may manage access to the distributed collaborative service unit by creating a finite state machine. For example, by creating a finite state machine for an access request from a client, the access requests for the same distributed collaborative service unit can be aggregated by the finite state machine and then sent to the distributed collaborative service unit, so that the number of connections created for the access request from the intermediate node by the distributed collaborative service unit can be reduced, and the access pressure of the distributed collaborative service unit can be reduced.

In addition, according to the embodiment of the present invention, the correspondence between the consistent hash value of the user tenant, which is calculated according to the consistent hash algorithm, and the plurality of distributed collaborative service units may be recorded in the global routing table. For example, the intermediate node may query the global routing table according to a hash value corresponding to a user tenant for which the request is directed, which is included in the request related to the address service sent by the client, so as to obtain a distributed collaborative service unit corresponding to the user tenant, and send the request to the distributed collaborative service unit. In this case, the client does not need to include the user tenant information in the request related to the address service, but only needs to include the hash value calculated according to the consistent hash algorithm, so that the intermediate node can obtain the corresponding distributed cooperative service unit according to the hash value, and forward the request to the distributed cooperative service unit.

In the network processing method provided by the embodiment of the invention, the intermediate node is arranged between the client and the distributed cooperative service unit which provides the address-related service for the client, so that the request sent by the client is routed to the corresponding distributed cooperative service unit according to the global routing table, thereby avoiding storing the global routing table in each client and reducing the maintenance cost of the global routing table; the data management center is arranged to store the global routing table so as to further ensure the global state consistency of the global routing table and ensure that the global routing table can be dynamically updated, thereby supporting the online migration of the registered address; meanwhile, by introducing the user tenant information, the intermediate node queries the corresponding distributed cooperative service unit according to the user tenant information, so that the service is decoupled from the distributed cooperative service unit information, and the service access cost is reduced.
