Description
Technical Field
Embodiments of the present invention relate to the field of wireless communications technologies, and in particular, to a method and an apparatus for adjusting network parameters, an electronic device, and a storage medium.
Background
With the development of wireless communication technology, a large amount of network data needs to be transmitted in a wireless network environment. Since the bandwidth occupation can directly affect the transmission quality of the network data, in order to improve the transmission quality of the network data, the bandwidth occupation of the network data can be adjusted through the network parameters.
Network data may be transmitted over a variety of channel types, such as fiber, coated wire, microwave, satellite, ad hoc, etc. Different channel types correspond to different bandwidth and delay conditions, and the bandwidth and delay conditions corresponding to some channel types are greatly different. At present, when network data is transmitted in different channel types, different network parameters need to be manually set to adjust the bandwidth occupation condition in order to ensure the transmission quality of the network data. Or the server adjusts the bandwidth occupation condition through the information fed back to the server by the client. For example, the audio and video display terminals can feed back the display conditions to the video server, and the video server adjusts the occupied bandwidth through a rate coding strategy, so as to improve the audio and video quality and service through bandwidth adjustment. However, the server can only reduce the occupied bandwidth of the network data according to the information fed back by the client, which results in the waste of the bandwidth. It should be noted that, when the network data is audio data or video data, if the network parameters cannot be adjusted in time according to the bandwidth occupation, the data loading pause phenomenon at the client is more serious.

The present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant elements of the present invention are shown in the drawings. Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a network parameter adjusting method according to an embodiment of the present invention, where this embodiment is applicable to a situation where transmission bandwidth data required by a server is determined by a network device, so that the server flexibly adjusts a network parameter according to the transmission bandwidth data, and the method may be executed by a network parameter adjusting apparatus, which may be implemented by software and/or hardware, and may be generally integrated in an electronic device, which may be a network device. Network structures formed by network devices are shown in fig. 2, and the network devices according to the embodiment of the present invention may also be formed into other network structures than those shown in fig. 2. Accordingly, as shown in fig. 1, the method comprises the following operations:
and S110, determining a data transmission path matched with the data request.
The data request may be a signal sent by a data requesting end, and is used to request a server to obtain network data. The network device may be a channel connection and selection gateway device. For example, a network device may include, but is not limited to, a switch or router. The network data can be data requested by a data request terminal to a server. The data request terminal may be a device for sending a data request to the server, may be a client device, and the like. For example, the network data may include audio data, video data, text data, picture data, and the like. The embodiment of the invention does not limit the specific data type of the network data. The data transmission path may be a transmission path of network data matched with the data request.
Specifically, the data request terminal may send a data request to the server. Accordingly, a network device between the data request end and the server can forward the data request to the server. After receiving the data request, the server may analyze the data request to obtain an analysis result corresponding to the data request, and send the analysis result corresponding to the data request to the network device for calculating the data transmission path. Optionally, the network device for calculating the data transmission path may be a network device directly connected to the server in communication, or may be any network device between the data request end and the server. If only one network device exists between the data request end and the server, the network device can forward the data request and send network data, and can determine a data transmission path according to an analysis result sent by the server.
In an optional embodiment of the present invention, determining a data transmission path matching the data request may include: receiving a request response IP (Internet Protocol) address determined by the server according to the data request; the request response IP address comprises a source IP address and a destination IP address, or the request response IP address comprises the destination IP address; and calculating a data transmission path according to the request response IP address.
The request response IP address can be at least one IP address matched with the data request and used for feeding back network data to the data request end. The source IP address may be an IP address of a server that the data requester requests network data. The destination IP address may be an IP address of the data requesting end.
In the embodiment of the invention, after receiving the data request, the server can analyze the IP address of the data request end according to the data request. If the IP address of the server changes in real time, the server needs to send the real-time IP address of the server and the IP address of the data request end to the network device for calculating the data transmission path at the same time. Correspondingly, the network device for calculating the data transmission path can register the real-time IP address of the server and the IP address of the data request end, so that the network device for calculating the data transmission path calculates the data transmission path by adopting any path calculation method according to the real-time IP address of the server and the IP address of the data request end. If the number of servers is only one and the IP address is uniquely fixed, the server may register the IP address as a source IP address among the request response IP addresses in advance in the network device for calculating the data transmission path. If the network device for calculating the data transmission path has registered the IP address of the server in advance, the server only needs to send the IP address of the data request end to the network device for calculating the data transmission path, and after the network device for calculating the data transmission path completes registration of the IP address of the data request end, the data transmission path can be further calculated by adopting any path calculation method according to the IP address of the registered server and the IP address of the data request end. Alternatively, the path calculation method may include, but is not limited to, a shortest path calculation method, and the like.
In an optional embodiment of the present invention, before determining the data transmission path matching the data request, the method may include: acquiring link bandwidth related data according to an improved OSPF (Open Shortest Path First) protocol; wherein the improved OSPF protocol may include a bandwidth occupancy field and a channel type field; the link bandwidth associated data may include link bandwidth data and bandwidth usage data; and constructing and storing a link bandwidth database according to the link bandwidth related data.
Wherein the link bandwidth association data may be data associated with all communication link bandwidths in the network fabric. The bandwidth occupancy field and the channel type field may be fields added after opaque link state advertisement type, and the bandwidth occupancy field may be used to record the real-time bandwidth occupancy of the communication link; the channel type field may be used to record the channel type of the communication link. The link bandwidth data may be the bandwidth supported by each link. The bandwidth occupancy data may be used to characterize the bandwidth occupancy. For example, the bandwidth usage data may include the bandwidth occupancy and the number of different data transmission paths that use the bandwidth, and so on. The link bandwidth database may be used to store link bandwidth related data such as link bandwidth data and bandwidth occupation data.
In the embodiment of the present invention, the bandwidth occupancy rate field and the channel type field may be added to the opaque of the OSPF protocol to obtain the improved OSPF protocol. After the OSPF opaque function of each network device is turned on, each network device may obtain link bandwidth associated data according to the bandwidth occupancy field and the channel type field of the improved OSPF protocol, and analyze the link bandwidth associated data to obtain link bandwidth data and bandwidth occupancy data, so that each network device stores the obtained link bandwidth data and bandwidth occupancy data in the link bandwidth database. Alternatively, the link bandwidth database may be an opaque database.
In the embodiment of the present invention, a 4-byte bandwidth occupancy field and a 4-byte channel type field may be added to the opaque of the OSPF protocol. The format of the opaque message of the unmodified OSPF protocol is shown in fig. 3. After the OSPF opaque function is started, the switches or routers may obtain link bandwidth data and bandwidth occupation data of communication links of all switches or routers belonging to the same group, and specifically, each switch or router may send its own link bandwidth data and bandwidth occupation data to other switches or routers in a point-to-multipoint manner. The switch or the router stores the switch or the router itself and the received link bandwidth data and bandwidth occupation data in an opaque database, which may be stored in software of the switch or the router.
In an optional embodiment of the present invention, before determining the data transmission path matching the data request, the method may further include: under the condition that the link bandwidth associated data meets the data updating condition according to the improved OSPF protocol, acquiring the updated link bandwidth associated data according to the improved OSPF protocol; or, receiving updated link bandwidth related data synchronously sent by other network equipment; updating the link bandwidth database according to the updated link bandwidth associated data; wherein, the data updating condition comprises channel switching or bandwidth occupancy rate change exceeding a set threshold.
The data update condition may be a condition for determining whether the link bandwidth related data needs to be updated. The updated link bandwidth related data may be link bandwidth related data satisfying a data update condition. The set threshold may be a preset bandwidth occupancy.
In the embodiment of the present invention, before determining the data transmission path matching the data request, the network device may first obtain link bandwidth associated data according to the improved OSPF protocol, and determine whether the link bandwidth associated data satisfies a data update condition, and if the link bandwidth associated data satisfies the data update condition, take the link bandwidth associated data satisfying the data update condition as updated link bandwidth associated data; and if the link bandwidth associated data does not meet the data updating condition, the link bandwidth associated data is not updated. Or, when the link bandwidth related data of the network device does not satisfy the data updating condition, the network device may receive the updated link bandwidth related data synchronously transmitted by other network devices. Thus, the network device can update the link bandwidth database according to the updated link bandwidth related data or the received updated link bandwidth related data.
In the embodiment of the present invention, the specific process of determining whether the link bandwidth associated data meets the data update condition according to the improved OSPF protocol includes: the network device can analyze the link bandwidth associated data acquired in real time according to the improved OSPF protocol to obtain real-time link bandwidth data and real-time bandwidth occupation data, further compare the real-time link bandwidth data with the link bandwidth data in the link bandwidth database, and indicate channel switching, that is, that the link associated bandwidth data satisfies the data updating condition if the real-time link bandwidth data is different from the link bandwidth data in the link bandwidth database. If the real-time bandwidth occupation data exceeds a set threshold value, such as 30%, it indicates that the link-related bandwidth data meets the data updating condition. The embodiment of the invention does not limit the specific value of the set threshold.
And S120, calculating transmission bandwidth data corresponding to the data transmission path.
Wherein the transmission bandwidth data may be bandwidth-associated data of the data transmission path. For example, the transmission bandwidth data may include real-time bandwidth data, bandwidth occupation data, minimum bandwidth data, and channel type data corresponding to the data transmission path. The embodiment of the present invention does not limit the specific data content included in the transmission bandwidth data.
In the embodiment of the present invention, after determining the data transmission path, the network device for calculating the data transmission path may obtain the relevant data of the data transmission path, and perform data processing on the relevant data of the data transmission path to obtain the transmission bandwidth data corresponding to the data transmission path.
In an optional embodiment of the present invention, calculating transmission bandwidth data corresponding to the data transmission path may include: acquiring path associated data corresponding to a segment data transmission path in the data transmission path; the path associated data comprises channel type, channel bandwidth and bandwidth occupancy; calculating transmission bandwidth data according to the path associated data; wherein the transmission bandwidth data includes a target channel type, a target channel bandwidth, and a target bandwidth occupancy.
Wherein the segmented data transmission path may be at least one path unit constituting the data transmission path. The path association data may be data characterizing communication capabilities associated with the segmented data transmission path. The channel type may be a channel class in which network data is transmitted. The channel bandwidth may be the maximum data rate that the channel can achieve. The target channel type may be the channel type having the smallest bandwidth in all of the segmented data transmission paths. The target channel bandwidth may be a minimum value of channel bandwidths in all of the segmented data transmission paths. The target bandwidth occupancy may be a maximum of the bandwidth occupancies in all of the segmented data transmission paths.
In the embodiment of the present invention, after determining the data transmission path, the network device for calculating the data transmission path may analyze the data transmission path to obtain a segmented data transmission path, and may obtain path-related data corresponding to the segmented data transmission path according to a communication protocol. The network device for calculating the data transmission path can obtain the channel type, the channel bandwidth and the bandwidth occupancy rate by analyzing the path associated data, so as to further perform data processing on the channel type, the channel bandwidth and the bandwidth occupancy rate to obtain the target channel type, the target channel bandwidth and the target bandwidth occupancy rate.
And S130, transmitting the transmission bandwidth data to a server so that the server determines data feedback network parameters matched with the data request according to the transmission bandwidth data.
The data feedback network parameters may be used to increase or decrease the amount of data that can be transmitted by the network device per unit time, and may include, but are not limited to, parameters such as bit rate that are affected by transmission bandwidth. For example, the data feedback network parameter may be a bit rate or a code rate, and the specific parameter type of the data feedback network parameter is not limited in the embodiments of the present invention.
In the embodiment of the present invention, the network device may send transmission bandwidth data matched with the data request to the server, and after receiving the transmission bandwidth data, the server may obtain bandwidth data and bandwidth occupation data according to the transmission bandwidth data, and determine a data feedback network parameter matched with the data request according to the bandwidth data and the bandwidth occupation data.
In a specific application scenario, after a switch or router for forwarding a data request receives the data request sent by a client, the switch or router for forwarding the data request forwards the data request to a video server, the video server parses the data request to obtain a client IP address, and registers the client IP address and the video server's own IP address in a switch or router for calculating a data transmission path, and the switch or router for calculating the data transmission path can calculate the lowest channel type, channel bandwidth and bandwidth occupancy from the server IP address to the client IP address according to an opaque database and feed back the lowest channel type, channel bandwidth and bandwidth occupancy to the video server. The video server determines a coding strategy according to the lowest channel type, channel bandwidth and bandwidth occupancy rate, and adjusts the code rate (which can be increased, reduced or not) according to the coding strategy, so as to provide the most suitable and optimal service. When the channel type of the data transmission path changes or the bandwidth occupancy rate change amplitude exceeds a set threshold, the switch or the router updates the link bandwidth data and the bandwidth occupancy data in the opaque database of the switch or the router, and sends the current link bandwidth data and the bandwidth occupancy data to other switches or routers used for calculating the data transmission path, so that the link bandwidth data and the bandwidth occupancy data in the opaque database of all switches or routers used for calculating the data transmission path are updated. And the switch or the router used for calculating the data transmission path further sends the updated self link bandwidth data and bandwidth occupation data to the video server according to the IP address of the video server. At this time, the video server may determine a coding strategy according to the updated link bandwidth data and bandwidth occupation data, and adjust the code rate (which may be increased, decreased or not) according to the coding strategy as needed. That is, the switch or router for calculating the data transmission path can calculate the lowest channel type, channel bandwidth and bandwidth occupancy rate from the server IP address to the client IP address according to the updated opaque database, and feed the lowest channel type, channel bandwidth and bandwidth occupancy rate back to the video server, and the video server can complete the timely sensing of channel switching and bandwidth change according to the feedback data, thereby achieving the effect of timely and dynamically adjusting the coding strategy and code rate as required by the video server.
In the technical solution of this embodiment, the network device may determine a data transmission path matching the data request, and calculate transmission bandwidth data according to the determined data transmission path, so that the transmission bandwidth data may be further sent to the server. The server may determine data feedback network parameters matching the data request based on the received transmission bandwidth data. The server can analyze the transmission bandwidth data sent by the network equipment and determine the bandwidth and the bandwidth occupation condition of the data transmission path according to the analysis result, so that the server can dynamically adjust the data feedback network parameters according to the bandwidth and the bandwidth occupation condition, and the server can feed back the network data according to the adjusted data feedback network parameters. That is, the technical scheme of the embodiment of the invention can realize the automatic adjustment of the bandwidth occupation condition as required without human intervention, solves the problems of low efficiency and poor flexibility of the existing network parameter adjustment, realizes the automatic adjustment of the network parameters as required, improves the adjustment efficiency of the network parameters and improves the flexibility of the network parameter adjustment.

If the IP address of the server changes in real time, the server needs to send the real-time IP address of the server and the IP address of the data request end to the network device for calculating the data transmission path at the same time, that is, the real-time IP address of the server is used as the source IP address, and the IP address of the data request end is used as the destination IP address. If the number of the servers is only one and the IP address is unique and fixed, the servers may register the IP address in the network device for calculating the data transmission path in advance, use the server IP address as the source IP address in the request response IP address, and use the data request end IP address obtained by parsing as the destination address, and at this time, the servers only need to send the data request end IP address to the network device for calculating the data transmission path.

In a specific example, the codec function may be configured in one video server at the same time, or may be configured in different video servers respectively. For example, the encoding function may be configured in an encoding video server and the decoding function may be configured in a decoding video server. The encoding video server can encode the network data and send the encoded data to a switch or a router on the encoding video server side, the switch or the router on the encoding video server side can send the encoded data to a switch or a router on the opposite end, the switch or the router on the opposite end can send the encoded data to the decoding video server, and the decoding video server performs decoding operation on the encoded data and sends the decoded data to the data request end.
