Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The service distribution method provided by the embodiment of the invention is applied to an edge cloud system, the edge cloud system comprises a cloud gateway, fig. 1 is a schematic structural diagram of the cloud gateway provided by the embodiment of the invention, and as shown in fig. 1, the cloud gateway comprises a controller and a plurality of virtual network elements. The virtual network element is installed in hardware entity equipment (not shown in fig. 1) such as a filtering server or a deep packet inspection server, and is used for implementing functions such as network traffic analysis or forwarding. In order to facilitate iteration and expansion, the controller adopts a micro-service architecture and mainly provides the following three types of network services:
1. virtual network element registration and allocation service: the method includes the steps of providing a hypertext Transfer Protocol (HTTP) interface for a virtual network element to call for registration, and allocating a network service to the virtual network element, specifically, sending a service resource of the network service to the virtual network element, where the service resource is an Internet Protocol (IP) address and a port of the network service, and the allocated network service includes a connection service and an acquisition service.
2. Connection service: the configuration is issued to the virtual network element in a Google Remote Procedure Call (GRPC) mode, and a connection request of the virtual network element is received.
3. Collecting service: and receiving a message sent by the virtual network element through a User Datagram Protocol (UDP) and forwarding the message to a card message queue.
Fig. 2 is a flowchart of a service allocation method according to an embodiment of the present invention, where the service allocation method is applied to a cloud gateway, and an execution subject of the service allocation method is a controller in the cloud gateway. As shown in fig. 2, the service allocation method includes:
Specifically, a virtual network element that needs to be accessed into the cloud gateway is called a target virtual network element, and in order to complete access, the target virtual network element needs to register with the controller, where one implementation is that the target virtual network element sends a registration request to the controller. The registration request carries a network element identifier of the target virtual network element, and the network element identifier carries a type of the target virtual network element.
The network element identifier may be generated when the virtual network element is created, and is used to uniquely represent the virtual network element, and the network element identifiers of different virtual network elements are different from each other. The network element identification comprises a first sub-identification and a second sub-identification.
Table 1 is a definition table of the first sub-identifier, and as shown in table 1, the first sub-identifier includes 8 bytes, which are sequentially called byte 1, byte 2, byte 3, byte 4, byte 5, byte 6, byte 7, and byte 8 from high to low.
Table 1 definition table of first sub-id
Wherein, byte 1 and byte 2 are used to indicate the number of the machine room in which the hardware entity device for installing the virtual network element is located, for example, a hexadecimal number FA00 is used to indicate the number of a certain machine room, and then byte 1 and byte 2 of the first sub-identifier of the virtual network element in all the hardware entity devices in the machine room are both set to be FA 00.
Byte 3, byte 4, byte 5, and byte 6 may be customized according to actual requirements, which is not specifically limited in the embodiment of the present invention.
Byte 7 is used to indicate the type of the virtual network element, and it should be noted that the type of the virtual network element may be divided according to its function, for example, the type of the virtual network element includes a virtual switch, a virtual client device, and the like, where the virtual switch also includes a virtual access switch, a virtual service switch, and the like. As a specific example, if the access virtual access switch is represented by a hexadecimal number 0x01, byte 7 of the first sub-id of all virtual network elements of the type virtual access switch is set to 0x 01; using hexadecimal number 0x02 to represent the virtual service switch, byte 7 of the first sub-identifier of all virtual network elements of which the type is the virtual service switch is set to be 0x 02; using the hexadecimal number 0x11 to represent the virtual client device, byte 7 of the first sub-identity of all virtual network elements of type virtual client device is set to 0x 11.
Byte 8 is used to represent the number of the virtual network element, and when the virtual network element in any hardware entity device is numbered, the value of byte 8 is sequentially incremented, for example, if only 16 virtual network elements exist in a certain hardware entity device and the types of the virtual network elements are all virtual client devices, 16 integers from 0x01 to 0x10 are used to represent the number of 16 virtual network elements respectively.
The second sub-identifier is a hexadecimal number corresponding to the management internet protocol address of the hardware entity device for installing the virtual network element, the management internet protocol addresses of all the virtual network elements in the same hardware entity device are the same, and the management internet protocol addresses of the virtual network elements in different hardware entity devices are different from each other.
The network element identifier may be obtained by splicing the first sub-identifier and the second sub-identifier, for example, the first sub-identifier is spliced at the front and the second sub-identifier is spliced at the back. As a specific example, if the first sub-identifier of a certain virtual network element is 11667788FFFF6601 hexadecimal number and the second sub-identifier is C0a80114 hexadecimal number, the network element is identified as 11667788FFFF6601C0a80114 hexadecimal number.
It should be noted that, the registration request may also carry a management internet protocol address and a port of the hardware entity device that installs the target virtual network element, in addition to the network element identifier of the target virtual network element.
If the controller receives the registration request sent by the target virtual network element, the controller can analyze the registration request, obtain the network element identifier of the target virtual network element carried in the registration request, and further obtain the type of the target virtual network element carried in the network element identifier.
Specifically, a number of network services, such as a connection service and an acquisition service, are built into the controller. When the controller receives a registration request sent by a target virtual network element, network services need to be allocated to the target virtual network element.
The types and the number of the virtual network elements that can be carried by different network services may be the same or different, and in general, some network services can carry multiple types of virtual network elements, some network services can only carry one type of virtual network element, some network services can carry multiple virtual network elements, and some network services can only carry one virtual network element.
In the embodiment of the invention, the cloud gateway is preset with the corresponding relation between the network service and the type of the virtual network element, if the controller receives a registration request sent by a target virtual network element, the registration request can be analyzed to obtain the network element identifier of the target virtual network element carried in the registration request, further obtain the type of the target virtual network element carried in the network element identifier, and then determine a plurality of first candidate services corresponding to the target virtual network element in a plurality of preset network services based on the corresponding relation between the network service and the type of the virtual network element.
Specifically, because a plurality of other virtual network elements exist in the cloud gateway besides the target virtual network element, the virtual network elements may be using a plurality of network services in the controller, and in order to ensure that the network service allocated to the target virtual network element is effective, the controller needs to determine available first candidate services among a plurality of first candidate services corresponding to the target virtual network element, and call each available first candidate service as a second candidate service, thereby obtaining a plurality of second candidate services.
And step 204, determining a plurality of target services in the second candidate services according to a load balancing algorithm.
In particular, load balancing refers to the spreading of requests or data across several operating units for execution to collectively complete a work task with the goal of optimizing resource usage, maximizing throughput, and minimizing response time by scheduling clusters. Through a load balancing algorithm, a plurality of better target services can be determined from a plurality of second candidate services corresponding to the target virtual network element to be allocated to the virtual network element. The load balancing algorithm may be a polling method, a random method, a source address hashing method, a weighted polling method, a weighted random method, a minimum concatenation method, or the like.
It should be noted that the plurality of target services include at least one connection service, or at least one collection service, or at least one connection service and at least one collection service.
Specifically, the service resource of the target service refers to a management internet protocol address and a port of the target service, and the controller sends the management internet protocol address and the port of the target service to the target virtual network element, so that the allocation of the network service is completed.
According to the service allocation method provided by the embodiment of the invention, the registration request sent by the target virtual network element carries the type of the target virtual network element, so that the controller can determine a plurality of first candidate services corresponding to the target virtual network element in a plurality of preset network services according to the type of the target virtual network element, then determine a plurality of available first candidate services in the plurality of first candidate services to obtain a plurality of second candidate services, then determine a plurality of better target services in the plurality of second candidate services based on a preset load balancing algorithm, and finally send the service resource of each target service to the target virtual network element, thereby completing the allocation of the network services.
Further, the detailed description of the step 202 in the embodiment of the present invention is that, determining, according to the type, a plurality of first candidate services corresponding to the target virtual network element in a plurality of preset network services, which includes:
step 2021, a preset service carrying capability table is called, wherein a service identifier corresponding to each network service, and a type and a number of virtual network elements that can be carried are stored in the service carrying capability table in an associated manner.
Specifically, each network service is built in the controller, and after the network service is built, the network service needs to be registered, for example, the carrying capacity of the network service is stored in the service carrying capacity table, and after the network service is registered, subsequent distribution can be performed. It should be noted that the service bearer capability table is stored in the database, in which the service identifier corresponding to each network service, the type and number of the virtual network elements that can be borne are stored in association.
It should be noted that the service carrying capacity table specifically includes a connection service carrying capacity sub-table and a collection service carrying capacity sub-table, where the connection service carrying capacity sub-table corresponds to the connection service, and a service identifier corresponding to each connection service, and a type and a number of virtual network elements that can be carried are stored in association with the connection service; the collection service bearing capacity sub-table corresponds to collection services, wherein service identification corresponding to each collection service, and types and number of virtual network elements capable of bearing are stored in an associated manner.
If a certain network service is a connection service, after the network service is registered, the bearing capacity of the network service is stored in a connection service bearing capacity sub-table, and if a certain network service is an acquisition service, after the network service is registered, the bearing capacity of the network service is stored in an acquisition service bearing capacity sub-table.
Step 2022, sequentially using each of the network services as a first service to be analyzed, and determining whether the type of the virtual network element that can be carried by the first service to be analyzed is consistent with the type of the target virtual network element.
Specifically, each network service is sequentially used as a first service to be analyzed, the type of the virtual network element that can be carried by the first service to be analyzed is obtained by querying the service carrying capacity table, the type is compared with the type of the target virtual network element, and whether the two types are consistent or not is judged.
Step 2023, if the service to be analyzed is consistent with the target virtual network element, determining the first service to be analyzed as the first candidate service corresponding to the target virtual network element.
Specifically, if the type of the virtual network element that can be carried by the first service to be analyzed is consistent with the type of the target virtual network element, it is indicated that the first service to be analyzed can carry the target virtual network element, and the first service to be analyzed is referred to as a first candidate service corresponding to the target virtual network element, so that a plurality of first candidate services corresponding to the target virtual network element can be determined.
Further, the above step 203 is described in detail in the embodiment of the present invention, that is, in a plurality of first candidate services, taking each available first candidate service as a second candidate service to obtain a plurality of second candidate services, where the method includes:
step 2031, invoking the service bearing capacity table and a preset allocated service table, wherein the allocated service table stores service identifiers corresponding to each network service and network element identifiers of the loaded virtual network elements in association.
Specifically, the service carrying capability table has been described in detail in the foregoing embodiments, and is not described herein again. The allocated service table is stored in a database, wherein service identifiers corresponding to each network service and network element identifiers of the loaded virtual network elements are stored in an associated manner.
Step 2032, sequentially using each of the first candidate services as a second service to be analyzed, and comparing the number of virtual network elements that can be borne by the second service to be analyzed with the number of virtual network elements that have been borne.
It should be noted that the number of the virtual network elements that can be carried by the second service to be analyzed is obtained by querying the service carrying capability table, and the number of the virtual network elements that are carried by the second service to be analyzed is obtained by querying the allocated service table, where the number of the virtual network elements that are carried by the second service to be analyzed is specifically obtained by counting the number of the network element identifiers of the virtual network elements that are carried by the second service to be analyzed in the allocated service table.
Step 2033, if the number of the virtual network elements that can be carried by the second service to be analyzed is greater than the number of the carried virtual network elements, determining the second service to be analyzed as the second candidate service.
Specifically, if the number of the virtual network elements that can be carried by the second service to be analyzed is greater than the number of the carried virtual network elements, it is indicated that the second service to be analyzed is available and can be used by the target virtual network element, and the second service to be analyzed is referred to as a second candidate service, so that a plurality of second candidate services can be determined.
Further, before comparing the number of virtual network elements that can be carried by the second service to be analyzed with the number of virtual network elements that have already been carried in step 2032, the method for allocating a service further includes: and acquiring the number of the virtual network elements loaded by the second service to be analyzed according to the network element identification of the virtual network element loaded by the second service to be analyzed.
Specifically, the number of the virtual network elements that have been carried by the second service to be analyzed is obtained by counting the number of the network element identifiers of the virtual network elements that have been carried by the second service to be analyzed in the allocated service table.
Further, after determining a plurality of target services among a plurality of second candidate services in step 204, that is, according to a preset load balancing algorithm, the service allocation method further includes: and storing the network element identification of the target virtual network element in the allocated service table, and associating the network element identification with the service identification of each target service.
Specifically, after determining a plurality of target services allocated to the target virtual network element, the controller stores the network element identifier of the target virtual network element in the allocated service table, and associates the network element identifier of the target virtual network element with the service identifier of each target service in the allocated service table, so as to update the allocated service table and ensure the accuracy of subsequent service allocation.
As a preferred embodiment, the embodiment of the present invention describes a complete flow of a service allocation method:
first, the following data tables are defined in the database, and it should be noted that all services described in the following data tables are web services.

It should be noted that the service includes a connection service and/or an acquisition service, and correspondingly, the service carrying capacity table includes a connection service carrying capacity sub-table and/or an acquisition service carrying capacity sub-table, where the connection service carrying capacity sub-table is used to store carrying capacity information of the connection service, such as a service identifier of the connection service, a type of a virtual network element that can be carried by the connection service, and a number and description information of the virtual network elements that can be carried by the connection service; the collection service bearing capacity sub-table is used for storing bearing capacity information of the collection service, such as a service identifier of the collection service, a type of a virtual network element that can be borne by the collection service, and a number and description information of the virtual network element that can be borne by the collection service.
Allocated services table: for storing allocated service information, such as a service identification of the service and a network element identification of a virtual network element that the service has carried. It should be noted that, since the service includes a connection service and/or an acquisition service, the service identifier in the allocated service table specifically includes a service identifier of the connection service and/or a service identifier of the acquisition service.
When a new connection service or an acquisition service is added to the controller, the newly added service needs to be registered, that is, the load capacity information of the service is stored in the service load capacity table, specifically, if the newly added service is a connection service, the load capacity information of the connection service is stored in the connection service load capacity sub-table, and if the newly added service is an acquisition service, the load capacity information of the acquisition service is stored in the acquisition service load capacity sub-table. Optionally, the service information may also be stored in a service table.
If the target virtual network element needs to be accessed into the cloud gateway, the target virtual network element sends a registration request to the controller in order to complete the access, wherein the registration request carries a network element identifier of the target virtual network element, a management internet protocol address and a port.
The controller receives a registration request sent by a target virtual network element, analyzes the registration request, obtains a network element identifier of the target virtual network element carried in the registration request, and further obtains the type of the target virtual network element carried in the network element identifier. It should be noted that the controller may further store the parsing result in the virtual network element table and the virtual network element type table.
The controller calls the service bearing capacity table, namely the connection service bearing capacity sub-table and/or the collection service bearing capacity sub-table, and inquires, so that a plurality of first candidate connection services corresponding to the target virtual network element are determined from a plurality of connection services according to the type of the target virtual network element, and/or a plurality of first candidate collection services corresponding to the target virtual network element are determined from a plurality of collection services.

As shown in fig. 3, the service allocation method includes:
Specifically, the target virtual network element needs to register with the controller in order to complete access, and one implementation manner is that the target virtual network element sends a registration request to the controller. The registration request carries a network element identifier of the target virtual network element, and the network element identifier carries a type of the target virtual network element.
