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 first embodiment is as follows:
as shown in fig. 1, which is a flowchart illustrating a communication method according to a first embodiment of the present invention, the communication method may include the following steps:
step 101: a server receives a public port connection request sent by a client; the connection request comprises the service to be accessed.

Compared with the prior art that a single-port service is adopted, one service in the embodiment of the invention can have a plurality of ports, can select idle ports for clients to provide service, can increase the number of clients capable of being served compared with the single-port service, and can effectively avoid the conditions of service speed reduction and congestion of the clients.
To further understand the communication method provided by the embodiment of the present invention, the following further description includes the following contents:
1) wherein, in one embodiment, the embodiment of the invention is suitable for net.tcp service and http service. Here, taking a net.tcp service as an example, a configuration method of a common port and a service port in the embodiment of the present invention is described:
assuming that there are three services provided, which are a performance service, a resource service, and an alarm service, respectively, the definition of the port includes:
< | A! -defining a common port- >: < add key ═ DisClientResourceProort >
< | A! -defining service ports for resource traffic- >: < add key ═ value ═ 4503,4504,4505,4506,4507'/>, of "resourcedataport
< | A! -defining service ports for performance services- >: < add key ═ performanedataport ═ value ═ 4513,4514,4515,4516,4517'/>
< | A! -defining service ports for alarm services- - >: < add key ═ AlarmDataPort "value ═ 4523,4524,4525,4526,4527"/>, and
the public port is a fixed open port, and is used for providing service for the client to initially apply for the service channel resource and dynamically allocating the service port for the client according to the busy degree of the service port.
The service port is used for providing the accessed service data for the client after establishing connection with the client.
After each port is defined, if each port can be used to provide a corresponding function, the following three operations need to be performed on each defined port: firstly, creating a service object instance, and secondly, binding a public port service interaction interface class for the service object instance; and thirdly, opening the port to provide corresponding service. Specifically, continuing with the above example, the common port and the service port are described separately:
1. for a common port:
(1) creating a service object instance:
creating a net.tcp service system model class object instance for public port services, an example method may be as follows, assuming the object name is svrPublic:
ServiceHost svrPublic；
(2) binding a public port service interaction interface class and a net.tcp basic service address for a service object instance:
for the public port service interactive interface class appointed between the clients, the responsibility is to receive the client request and return the processing result, for example, the assumed class name is svrPublicService. If the IP of the service address is assumed to be svrp and the port of the net.tcp service address is assumed to be svrPublicPORT, the binding example method is as follows:
svrPublic＝new ServiceHost(typeof(svrPublicService),new Uri[]{“net.tcp:// svrIP:svrPublicPORT”)。
(3) opening a port:
an exemplary method is as follows:
svrPublic.Open()；
2. for service port
(1) Creating a service object instance:
creating a net.tcp service system model class object instance for public port service, assuming the object name is svrYewu, the method is as follows:
ServiceHost svrYewu；
(2) binding a public port service interaction interface class and a net.tcp basic service address for a service object instance:
for the public port service interactive interface class appointed between the clients, the role is to receive the client request and return the processing result, for example, the assumed class name is svrYewuService. If the IP of the service address is assumed to be svrjp and the port of the net.tcp service address is assumed to be svrYewuPORT, the binding example method is as follows:
svrYewu＝new ServiceHost(typeof(svrYewuService),new Uri[]{“net.tcp://svrIP:svrYewuPORT”)。
(3) opening a port:
an exemplary method is as follows:
svrYewu.Open()；
(4) in the manner of the above (1) to (3), circularly creating and opening all service ports:
an exemplary method is as follows:
foreach (int port in service port list)
{
Creating open traffic port services
}。
Of course, the method for creating and configuring the port is only an exemplary illustration, and any reasonable method may be adopted according to actual needs in specific implementation, and is applicable to the embodiment of the present invention, and the present invention is not limited to this.
2) In an embodiment of the present invention, to implement that the selected service port is relatively reasonable, and a relatively idle port can be selected to provide services, in step 102, a service port whose connection number does not reach the upper limit of the connection number is selected from at least one service port of the service to be accessed, which can be implemented in one of the following two manners:
the first method is as follows: and selecting the service port with the minimum connection number from the at least one service port of the service to be accessed. Therefore, the selected service port with the minimum number of the summary connections enables the loads of all the service ports to be balanced, and service for accessing services can be effectively provided for the client.
In specific implementation, a polling method may be used to determine which service port has the smallest number of connections, or a number comparison method in the prior art may be used to determine which service port has the smallest number of connections, which is not limited in the present invention.
The second method comprises the following steps: and selecting service ports with the connection number smaller than the preset number from at least one service port of the service to be accessed, wherein the preset number is smaller than the upper limit of the connection number. Therefore, a better port is selected, so that the selected port can be ensured to be idle, and the service can be provided for the client well.
It should be noted that any method capable of selecting a relatively idle port from at least one service port is applicable to the embodiment of the present invention, and the present invention is not limited to this.
3) Wherein, in one embodiment, some services are actually associated, such as the performance service and the alarm service, which generally provide services for the client at the same time. Therefore, in the embodiment of the present invention, in order to facilitate the user to access the associated service, the method may further include the following steps:
step A1: determining whether the associated service of the service to be accessed exists or not according to a pre-stored service association relation;
step A2: if the connection number of the service ports does not reach the upper limit of the connection number, the service ports with the connection number not reaching the upper limit of the connection number are selected from at least one service port of each associated service, and the port identification of the selected service port is sent to the client through the public port, so that the client establishes connection with the selected service port of the associated service.
For example, when the client requests to access the performance service, the port identifier of the service port of the alarm service associated with the performance service is also sent to the client, so that the client can access the alarm service without requesting the service port of the alarm service again while accessing the performance service. Therefore, the client does not need to send a public port connection request for requesting to access the alarm service, and the server does not need to process the connection request, so that the processing resources of the server can be saved, and the bandwidth can be saved.
It should be noted that the port identifier of the service port associated with the service may be sent to the client together with the port identifier of the service port of the service to be accessed, or may be sent separately.
Example two
Based on the same inventive concept, an embodiment of the present invention further provides a communication method, as shown in fig. 2, which is an exemplary flowchart of the method, and may include the following steps:
step 201: the client sends a public port connection request to the server; the connection request comprises the service to be accessed.
Step 202: after the connection is established between the public port and the server, the port identification of the service port of the service to be accessed, which is sent by the server through the public port, is received, and the service port is the service port of which the connection number selected from at least one service port of the service to be accessed does not reach the upper limit of the connection number after the connection is established between the server and the client through the public port.
Step 203: and after establishing connection with the service port corresponding to the service port identifier sent by the server, accessing the service to be accessed.
Therefore, after the client establishes connection with the server through the public port, the idle service port allocated by the server is obtained, and then the service to be accessed is accessed through the allocated service port. The method and the system can improve the speed of the client accessing the service to be accessed and avoid the client being squeezed.
In one embodiment, some services are actually associated, and if a service is not accessed, a public port connection request is sent to a server, and if the server is requested to allocate a service port, it obviously occupies more bandwidth and wastes processing resources of the server, so that, in order to avoid wasting bandwidth and saving processing resources of the server, in this embodiment of the present invention, it may further be:
step B1: and receiving the port identification of the service port of the associated service of the service to be accessed, which is sent by the server through the public port.
Step B2: and establishing connection with the service port corresponding to the port identification of the service port of the associated service. Therefore, the service port of the service to be accessed and the service port of the associated service can be obtained only by sending the public port connection request once, so that the access to the service to be accessed and the associated service is realized.
In summary, in the embodiment of the present invention, the client can obtain a relatively idle service port of the service to be accessed through the public port. The situations of service speed reduction and extrusion caused by single-port service in the prior art can be effectively avoided.
