S102: the client transmits the self internet access attribute information to the server by using the first channel.
The network port attribute information comprises the number of network ports and network port information supporting multi-queue characteristics.
The multi-queue feature means that one portal can support multiple channels. The port information of the multi-queue characteristic includes the number of channels that the port can support.

S104: and the server determines channel establishment information according to the network port attribute information transmitted by the client, the network port attribute information of the server and the current load of the server.
The channel establishing information comprises a target network port and the number of channels corresponding to the target network port.
For convenience of description, in the embodiment of the present invention, an example of a client is used for introduction. There may be multiple network ports on one client, and in practical application, the network port for establishing the channel may be referred to as a target network port.
The load-bearing capacity of the server is limited, and overload operation can affect the performance of the server, so that when the server selects a target network port and the number of channels corresponding to the target network port, the server can comprehensively consider the current load of the server in addition to the network port attribute information transmitted by the client and the network port attribute information of the server, and determine channel establishment information.
S105: and the server binds a corresponding transceiving thread for each channel in the channel establishment information and feeds the channel establishment information back to the client.

S106: and the client establishes a channel with the server according to the target internet access and the number of the channels corresponding to the target internet access included in the channel establishment information.
The target network port refers to a network port through which a client can establish a channel with a server, the number of the target network ports can be one or more, each target network port has the corresponding channel number, and the client can establish a plurality of channels with the server according to the channel number of each target network port.
Fig. 2 is a flowchart of a method for determining channel establishment information according to portal attribute information of a client, portal attribute information of a server, and a current load of the server according to an embodiment of the present invention, where the method includes:
s201: and determining the number of channels which can be established according to the self network port attribute information and the self current load.
The network port attribute information of the server includes the number of network ports of the server and the number of channels that each network port can carry.
The maximum carrying capacity of the server is known information, and the number of channels which can be supported by the current service can be determined by combining the current carrying capacity of the server with the current carrying capacity of the server.
The server can know which network ports are available according to the network port attribute information of the server, and the number of channels supported by the available network ports can be obtained.
The server may use the minimum value of the number of channels that can be supported by the current service and the number of channels that can be supported by the available network port as the number of channels that can be established.
S202: and selecting the network port supporting the multi-queue characteristic from the network port attribute information transmitted by the client as a first target network port.
In the embodiment of the present invention, the network ports supporting the multi-queue feature are collectively referred to as a first target network port. In practical application, the network port supporting the multi-queue feature can be preferentially selected to establish the channel.
S203: and judging whether the channel number of the multi-queue characteristic of the first target network port is larger than or equal to the number of channels which can be established.
When the number of channels of the multi-queue feature of the first target portal is greater than or equal to the number of channels that can be established, it indicates that the first target portal can satisfy the number of channels that need to be established, and at this time, S204 may be performed.
When the number of channels with the multi-queue characteristic of the first target portal is smaller than the number of channels that can be established, it indicates that the number of channels established by the first target portal cannot reach the number of channels that can be established, and at this time, other portals may be further selected to establish channels, that is, S205 is performed.
S204: and taking the first target network port as a target network port of the channel establishment information, and taking the number of channels which can be established as the number of the channels of the first target network port.
For example, it is assumed that the number of channels that can be established is 5, the number of channels with the multi-queue characteristic of the first target network port is 6, and the channel establishment information includes the target network port and the number of channels corresponding to the target network port, at this time, the first target network port is used as the target network port of the channel establishment information, and the number of channels is 5 as the number of channels of the first target network port.
S205: and taking the number of the channels with the multi-queue characteristic of the first target network port as the number of the channels of the first target network port, and calculating the difference value between the number of the channels which can be established and the number of the channels with the multi-queue characteristic of the first target network port.
For example, assuming that the number of channels that can be established is 5, the number of channels with the multi-queue characteristic of the first target portal is 3, and only 3 channels can be established at most depending on the first target portal, and the number of channels that can be established cannot be reached, at this time, the difference between the number of channels that can be established and the number of channels with the multi-queue characteristic of the first target portal is 2.
S206: and selecting a second target internet access corresponding to the difference value from the internet access attribute information of the client.
When the number of channels that can be established by the network ports supporting the multi-queue characteristic in the client cannot reach the number of channels that can be established, in order to meet the number of channels that need to be established, the network ports with the number equal to the difference value can be selected from the network ports without the multi-queue characteristic in the client to serve as second target network ports. And each second target network port corresponds to one channel.
S207: and taking the first target internet access and the second target internet access as target internet accesses of channel establishment information.
When the number of the channels with the multi-queue characteristic of the first target network port is smaller than the number of the channels which can be established, the network ports with the number equal to the difference value can be selected as second target network ports, and at the moment, the first target network ports and the second target network ports can be combined to be used as the target network ports of the channel establishment information; the number of channels of the channel establishment information is the sum of the number of channels with the multi-queue characteristic of the first target network port and the number of the second target network ports.
According to the technical scheme, the client mounts the shared directory exported by the server to the local to establish a first channel with the server; transmitting self internet access attribute information to a server by using a first channel; the network port attribute information comprises the number of network ports and network port information supporting multi-queue characteristics. In order to realize load balance of multi-client services, the server can determine channel establishment information according to the network port attribute information transmitted by the client, the network port attribute information of the server and the current load of the server; the channel establishing information includes the target network port and the number of the channels corresponding to the target network port. In order to ensure the availability of the channels, the server binds corresponding transceiving threads for each channel in the channel establishment information and feeds the channel establishment information back to the client, so that the client establishes the channel with the server according to the target internet access and the number of the channels corresponding to the target internet access included in the channel establishment information. In the technical scheme, the server determines the target network ports capable of establishing the channels and the number of the channels corresponding to the target network ports by depending on the processing capacity of the server and the network port attribute of the client, and binds one transceiving thread for each channel, so that the server can exert the service performance of the server to the maximum extent, and the performance and the competitiveness of the storage product are improved.
In the embodiment of the invention, the server side can dynamically adjust the number of the channels between the server side and the client side according to actual requirements. In practical application, the server can count the data transmission amount of each channel in a period time; and when the target channel with the data transmission quantity smaller than the preset threshold value exists, transmitting a command of canceling the target channel to the client, and canceling the target channel established with the server when the client receives the command of canceling the target channel transmitted by the server.
By canceling the channel with smaller data transmission quantity, the occupation of useless channels on the network port resources can be effectively avoided, and the utilization rate of the network port resources is improved.
In practical application, a situation that a new client needs to establish a channel with a server may exist, and when the server receives a channel establishment request transmitted by the new client, whether the establishment of the new channel is supported or not may be judged.
When the server can support the establishment of the new channel, a channel establishment instruction can be fed back to the new client;
when the server cannot support the establishment of a new channel, in order to release the internet access resources, so that the server can support the connection of a new client, at the moment, the server can select a target channel of which the data transmission quantity is smaller than a preset threshold value in a period time from the established channels, and transmit an instruction of canceling the target channel to the client so as to facilitate the client to cancel the target channel established with the server; when response information of the completion of the cancellation of the target channel transmitted by the client is received, the response information of the completion of the cancellation of the target channel is transmitted to the new client feedback channel establishment instruction client and the server, so that the server can conveniently feed back the channel establishment instruction to the new client.
The value of the cycle time and the value of the preset threshold may be set according to actual requirements, and are not limited herein.
The number of the channels between the server and the client is dynamically adjusted by depending on the data transmission quantity of each channel, so that the occupation of useless channels on the network port resources can be effectively avoided, and the utilization rate of the network port resources is improved.
In order to facilitate management of the channel information corresponding to each client, after receiving a response message of completing channel establishment fed back by the client, the server may record the client and the channel establishment information corresponding to the client to a preset storage space.
The server can quickly acquire the client currently connected with the server and the occupied internet access resources by inquiring the information recorded in the storage space.
