The service distribution method provided in the embodiment of the present application is applied to an edge cloud system, where the edge cloud system includes a cloud gateway, and fig. 1 is a schematic structural diagram of the cloud gateway provided in the embodiment of the present application, and as shown in fig. 1, the cloud gateway includes a controller 12 and a network element 11. The network element 11 is installed in a hardware entity device (not shown in fig. 1) such as a filtering server or a deep packet inspection server, and is configured to implement functions such as network traffic analysis or forwarding. It should be noted that, in this embodiment, unless otherwise specified, the Network element 11 is a Virtual Network element (VNF), specifically, the Network element 11 may be a Data center Network element, an access Network element, a service Network element, and the like, where the Data center Network element may be a Data Center Switch (DCSW), the access Network element and the service Network element may be a Virtual Switch (vSwitch, Virtual Switch), and the like, and each of the Network elements belongs to a fixed Network element cluster.
To facilitate iteration and expansion, the controller 12 employs a microservice architecture and provides mainly the following three types of network services:
Connection service: the configuration is issued to the network element 11 in a Google Remote Procedure Call (GRPC) manner, and a connection request of the network element 11 is received.
Collecting service: the receiving network element 11 receives a message sent by a User Datagram Protocol (UDP) and forwards the message to the card message queue.
It should be noted that the structural schematic diagram of the cloud gateway shown in fig. 1 is an example, the controller and the scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows, with the evolution of the system and the occurrence of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Fig. 2 is a flowchart of a service distribution method provided in an embodiment of the present application, where the service distribution method is applied to a cloud gateway, and an execution subject of the service distribution method is a controller 12 in the cloud gateway. As shown in fig. 2, the service allocation method includes:
210: receiving a registration request sent by an idle network element, wherein the registration request carries an idle network element identifier, and the idle network element identifier comprises a network element cluster identifier and a network element type identifier;
specifically, when a certain traffic channel needs to be established, the idle network element needs to register with the controller 12, where one implementation manner is that the idle network element sends a registration request to the controller 12. The registration request carries an idle network element identifier, and the idle network element identifier includes a network element cluster identifier and a network element type identifier.
The idle network element identifier may be generated as a network element identifier when creating a network element, and is used to uniquely represent the network element, and network element identifiers of different 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
In this embodiment, the number of the machine room may also be used as the network element cluster identifier, for example, a hexadecimal number FA00 is used to represent the number of a certain machine room, and then byte 1 and byte 2 of the first sub-identifier of the 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 this embodiment of the application.
Byte 7 is used to indicate the type of the network element, and it should be noted that the type of the network element may be divided according to its function, for example, the type of the 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, the access virtual access switch is represented by a hexadecimal number 0x01, and byte 7 of the first sub-identifier of all network elements of which the type is the 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 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 network elements of type virtual client device is set to 0x 11.
Byte 8 is used to represent the number of the network element, and when the network element in any hardware entity device is numbered, the value of byte 8 is sequentially incremented, for example, if only 16 network elements exist in a certain hardware entity device and the types of the network elements are all virtual client devices, 16 integers from 0x01 to 0x10 are used to represent the number of 16 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 network element, the management internet protocol addresses of all the network elements in the same hardware entity device are the same, and the management internet protocol addresses of the 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 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, in addition to carrying the idle network element identifier of the idle network element, the registration request may also carry the management internet protocol address and the port of the hardware entity device that installs the network element.
If the controller 12 receives the registration request sent by the idle network element, the registration request may be analyzed to obtain the idle network element identifier of the idle network element carried in the registration request, and further obtain the network element type identifier carried in the idle network element identifier.
220: determining candidate services in preset network services according to the network element type identifier;
specifically, several network services, such as a connection service and an acquisition service, are built into the controller 12. When the controller 12 receives a registration request sent by an idle network element, it needs to prepare to allocate network services to the network element.
The types and the number of the 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 network elements, some network services can only carry one type of network element, some network services can carry multiple network elements, and some network services can only carry one network element.
In this embodiment of the application, the cloud gateway presets a corresponding relationship between a network service and a type of a network element, and if the controller 12 receives a registration request sent by an idle network element, the registration request may be analyzed to obtain a network element identifier carried in the registration request, and further obtain a network element type identifier carried in the network element identifier and used for determining a target network element type, and then determine a candidate service among a plurality of preset network services based on the corresponding relationship between the network service and the type of the network element.
In an embodiment, the step of determining a candidate service in a preset network service according to the network element type identifier includes:
calling a preset service bearing capacity table, wherein a service identifier corresponding to each network service, and a bearing type identifier and the number of network elements capable of bearing are stored in the service bearing capacity table in an associated manner;
sequentially judging whether the bearing type identification capable of being borne by each network service is consistent with the network element type identification;
and if so, determining the network service as the candidate service.
It should be noted that each network service is built in the controller 12, 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, the subsequent distribution can be performed. Specifically, a service carrying capacity table is stored in the database, and a service identifier corresponding to each network service, a carrying type identifier of a network element that can be carried, and a number are stored in the service carrying capacity table in an associated manner.
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 connection services, and a service identifier corresponding to each connection service and types and numbers of network elements that can be carried are stored in association with the connection services; the collection service bearing capacity sub-table corresponds to collection services, wherein service identification corresponding to each collection service, and types and number of network elements capable of bearing are stored in association.
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.
230: determining a target network element in the network element cluster corresponding to the network element cluster identifier according to the network element cluster identifier, the network element type identifier and the candidate service;
in an embodiment, as shown in fig. 3, the step of determining, according to the network element cluster identifier, the network element type identifier, and the candidate service, a target network element in a network element cluster corresponding to the network element cluster identifier includes:
310: calling the service bearing capacity table and a preset distributed service table, wherein the distributed service table is stored with service identification corresponding to each network service and network element identification of a loaded network element in a correlated manner;
320: judging whether the number of the network elements which can be borne by the candidate service is larger than the number of the borne network elements or not;
if the number of the network elements which can be loaded by the candidate service is equal to the number of the loaded network elements;
330: and determining a non-idle network element in the network element cluster corresponding to the network element cluster identifier as a target network element, wherein the target network element type identifier of the target network element is the same as the network element type identifier.
It should be noted that, before the step of determining whether the number of network elements that can be carried by the candidate service is greater than the number of network elements that have already been carried, the method further includes: and acquiring the number of the network elements carried by the candidate services according to the network element identifiers carried by the candidate services. Determining the network element identification carried by the candidate service by calling an allocated service table, so as to determine the number of the network elements carried by the candidate service according to the network element identification carried by the candidate service; it is convenient to determine whether the number of network elements that can be carried by the candidate service is greater than the number of network elements that have already been carried.
It can be understood that, when the number of network elements that can be carried by the candidate service is equal to the number of network elements that have already been carried, that is, the candidate service has reached the upper limit of the number of carrying network elements, at this time, the controller 12 has no resource or space to manage the idle network elements, and therefore, a non-idle network element in the network element cluster corresponding to the network element cluster identifier is determined as a target network element, where a target network element type identifier of the target network element is the same as the network element type identifier.
Specifically, if there is a step in which the number of network elements that can be carried by the candidate service is equal to the number of network elements already carried, the step of determining a non-idle network element in the network element cluster corresponding to the network element cluster identifier as a target network element includes:
determining candidate network elements in the network element cluster corresponding to the network element cluster identifier according to the network element type identifier, wherein the candidate network element type identifier of the candidate network elements is the same as the network element type identifier;
acquiring network element information reported by each candidate network element;
and determining a target network element in each candidate network element according to the network element information.
Specifically, a plurality of working network elements, that is, the non-idle network elements, exist in the network element cluster corresponding to the network element cluster identifier, and a candidate network element is determined from the non-idle network elements having the same type identifier as the network element type identifier according to the network element type identifier, obviously, the candidate network element is already loaded in the candidate service as the non-idle network element, that is, the network element identifier of the candidate network element is stored in the allocated service table, so that the number of network elements that can be loaded by the candidate service does not need to be considered.
Further, network element information reported by each candidate network element is obtained, where the network element information may include candidate network element identifiers, operation state information, and the like of the candidate network elements, and specifically, the operation state information may include data traffic information, resource occupation information, and the like of the candidate network elements, and a target network element is determined in each candidate network element according to the network element information, that is, a candidate network element with smaller processing data traffic or less resource occupation may be determined as the target network element according to the data traffic information and the resource occupation information in the operation state information; so that the target network element has enough space to carry new traffic.
As shown in fig. 3, the step of determining a target network element in the network element cluster corresponding to the network element cluster identifier according to the network element cluster identifier, the network element type identifier, and the candidate service further includes:
340: if the number of the network elements which can be borne by the candidate service is larger than the number of the borne network elements, acquiring the number of idle network elements in the network element cluster corresponding to the network element cluster identifier;
350: judging whether the number of the idle network elements is larger than a preset idle network element threshold value or not;
if the number of the idle network elements is larger than the threshold value of the idle network elements;
360: and determining the idle network element as a target network element.
If the number of idle network elements is less than or equal to the idle network element threshold, referring to step 330:
and determining a non-idle network element in the network element cluster corresponding to the network element cluster identifier as a target network element, wherein the target network element type identifier of the target network element is the same as the network element type identifier.
It is understood that a standby network element, which may be the idle network element, is preset during the initial configuration of the network by the controller 12, and is used for the function expansion. The new traffic needs to be accessed or a part of the network elements need to be replaced when a fault occurs, and the like, so that idle network elements need to be reserved in each network element cluster, wherein the number of the reserved idle network elements is also a preset idle network element threshold, and the specific idle network element threshold can be set according to actual needs, which is not limited herein.
Specifically, if the number of network elements that can be carried by the candidate service is greater than the number of network elements already carried, that is, the controller 12 has a carrying capability for the network element type corresponding to the network element type identifier, at this time, the number of idle network elements in the network element cluster corresponding to the network element cluster identifier is obtained, so as to determine whether the number of idle network elements is greater than a preset idle network element threshold value; when the number of the idle network elements is greater than the idle network element threshold value, that is, enough idle network elements are available, determining the idle network elements as target network elements; when the number of the idle network elements is less than or equal to the idle network element threshold, that is, the number of the idle network elements is less, determining a non-idle network element in the network element cluster corresponding to the network element cluster identifier as a target network element, and specifically, determining a non-idle network element in the network element cluster corresponding to the network element cluster identifier as a target network element is described in the embodiment related to step 330, which is not described herein again, where a target network element type identifier of the target network element is the same as the network element type identifier.
240: determining a target service in the candidate services according to the target network element and a preset 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 the candidate services corresponding to the target network element to be allocated to the target 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 target service at least includes a connection service, or at least one collection service, or at least one connection service and at least one collection service.
250: and sending the service resource of the target service to the target network element.
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 12 sends the management internet protocol address and the port of the target service to the target virtual network element, thereby completing the allocation of the network service.
In an embodiment, after the step of determining a target service among the candidate services according to the target network element and a preset load balancing algorithm, the method further includes storing a target network element identifier of the target network element in the allocated service table, and associating the target network element identifier with a service identifier of each target service.
Specifically, after determining the target service allocated to the target network element, the controller 12 stores the target network element identifier of the target network element in the allocated service table, and associates the target network element identifier 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.
In an embodiment, before the step of receiving the registration request sent by the idle network element, different network services need to be set up in the controller 12, and the following data table is defined in the database, it should be noted that the services described in the following data table are all network services.
Service table: for storing service information such as service identification of the service, type of service, management internet protocol address of the service, port of the service and description information.
Virtual network element table: for storing virtual network element information, such as network element identification of the virtual network element, management internet protocol address of the virtual network element, port of the virtual network element, type and description information of the virtual network element.
