How to change communication strategies and communication means in real time according to the change of the current network in a complex and changeable network environment is a key part in the network communication technology.

The following introduces a system architecture to which the embodiments of the present application are applicable:

For example, users need to perform network communication in a game, and at this time, it is required that service data that the local user needs to send to the opposite user is transmitted as fast as possible over a communication link, and it is also required to ensure a low network delay and improve user experience. Besides, similar scenes such as voice, video and the like also need to be transmitted through the link.

Wherein, a corresponding link switching device may be deployed on the first client or the second client, such as: switching components, etc.; for example: if the first client sends the service data to the second client, the switching component can be deployed on the first client; otherwise, if the second client sends the service data to the first client, the switching component may be deployed on the second client. In addition, the above-mentioned switching component may automatically establish a first link between the first client and the second client by sending the first data packet, and then implement the exchange of an internet protocol address (IP) port and an external IP port between the first client and the second client based on the first link. After that, the first client and the second client can punch holes in parallel according to the intranet IP port and the extranet IP port of the opposite terminal, so that a second link between the first client and the second client is established. It should be understood that, in the embodiment of the present application, a method for switching a link will be described in detail by taking a switching component as an example, but an apparatus for executing the method of the embodiment of the present application is not limited to the switching component, and may also be a user of the switching component, that is, a first client, a second client, a first terminal, a second terminal, or the like, which is not limited in the embodiment of the present application.

Taking the distributed system as an example of a blockchain system, referring to fig. 2, fig. 2 is an optional structural schematic diagram of the distributed system 200 applied to the blockchain system, which is formed by a plurality of nodes (computing devices in any form in an access network, such as servers and user terminals) and clients, and a peer-to-peer (P2P) network is formed between the nodes, and the P2P protocol is an application layer protocol operating on a Transmission Control Protocol (TCP) protocol. In a distributed system, any machine, such as a server or a terminal, can join to become a node, and the node comprises a hardware layer, a middle layer, an operating system layer and an application layer. And the above-mentioned switching components are included in the link layer.

The handover method in this embodiment may be applied to the system architectures shown in fig. 1 and fig. 2, and may also be applied to other system architectures, which are not limited herein.
To better understand the proposed solution in the embodiment of the present application, a detailed flow in the embodiment is described below, please refer to fig. 4, which is a schematic diagram of an embodiment of a method for link handover provided in the embodiment of the present application, where the method includes:
401. a first link currently used for communication between a first client and a second client is determined.
In this embodiment, the switching component is actually a device for performing seamless switching on the first link and the second link on a link layer in combination with end-to-end connection between the first link and the second link, and the first client or the second client only needs to call a packet receiving and sending interface corresponding to the switching component, and the switching component can perform free switching on the communication link on the link layer in the process of communication between the first client and the second client.
The first link mentioned above may be the P2S link established by the switching component first sending the first packet.
402. Monitoring a first quality of a first link and a second quality of a second link within a preset time, wherein the first link and the second link are deployed in a link layer.
In this embodiment, if the communication link between the first client and the second client is to be directly and freely switched in the link layer through the switching component, starting from the aspect of determining the quality of the communication link, a link with a better current quality may be selected as the link in the current communication process. If the switching component determines that the first link is the current communication link between the first client and the second client when the communication process starts, after a period of time elapses, a phenomenon that the transmission effect is poor due to link jitter caused by changes in network environment and the like may occur, and the switching component may monitor the first quality of the first link and the second quality of the second link simultaneously within a preset time period. For example: the first link is always used for communication within 0-5s during communication, and if the link jitter occurs at 6s, the switching component may select to monitor the first quality of the first link and the second quality of the second link simultaneously within a preset time period, for example, within a time period of 6s-10s, so as to select a communication link with a better quality as the current communication process. Of course, the switching component is in a state of monitoring the quality of the first link and the second link in real time during the whole communication process, for example, the switching component is also required to monitor the quality of the two links within the time period of 10s to 15 s.
It should be noted that the preset time period described above can be set by a user according to actual application requirements, and 0-5s,6s-10s, and the like in this embodiment are examples for illustrating the embodiment of the present application in detail, and should not be limited thereto.
Optionally, in other embodiments, for the handover component to monitor the quality of the first link and the second link, the following may be performed: acquiring a service data packet from the first link and acquiring a first detection packet from the second link, wherein a packet header of the service data packet carries first detection information, and a packet header of the first detection packet carries second detection information; analyzing the service data packet and the first detection packet to obtain the first detection information and the second detection information; detecting a first quality condition of the service data packet in the first link according to the first detection information within the preset time length, and detecting a second quality condition of the second detection packet in the second link according to the second detection information; determining a first quality of the first link based on the first quality condition and determining a second quality of the second link based on the second quality condition.
In this embodiment, in order not to excessively increase the burden in the network communication process, the first detection information may be added in the packet header of the service data packet, so that the switching component may acquire the service data packet from the first link in the communication process, and then analyze the first detection information carried by the packet header in the service data packet, so as to detect the first quality condition of the first link by using the first detection information, and determine the first quality of the first link according to the first quality condition. In addition, since the second link is an alternative link that can be selected when the first link is in poor quality, for the second quality of the second link, second detection information may also be added to the packet header of the first probe packet, so that the switching component may acquire the first probe packet from the second link in the communication process, and analyze second detection information carried by the packet header in the first probe packet from the first probe packet, so as to detect the second quality condition of the second link according to the second detection information, thereby determining the second quality of the second link according to the second quality condition.
Optionally, in other embodiments, the above-mentioned first quality condition may include, but is not limited to, link delay information, fluctuation information or packet loss rate during transmission of the service data packet in the first link; of course, the above-mentioned second quality condition may include, but is not limited to, link delay information, fluctuation information or packet loss rate during transmission of the service data packet in the second link. Accordingly, the first quality of the first link or the second quality of the second link may be determined from aspects including, but not limited to, link delay information, fluctuation information, or packet loss rate. For example: assuming that the quality is 100 points, taking the packet loss rate as an example, the handover component detects that the packet loss rate of the first link is 35% and the packet loss rate of the second link is 28%, it is obvious that the quality of the first link is (1-35%). 100 ═ 65 points, and the quality of the second link is (1-28%). 100 ═ 72 points.
403. A mass difference between the first mass and the second mass is determined.
In this embodiment, the quality difference between the first quality and the second quality is determined, mainly because when the first link is assumed to have a negligible quality degradation, the link does not need to be switched, and communication can still be performed through the first link. Therefore, whether the link is switched or not is determined according to the quality difference between the two links, network jitter caused by switching in the communication process can be reduced, and the user experience is maximized.
It should be understood that the above-mentioned quality differences can be expressed in absolute value. For example: based on the example described in step 402, it is determined that the first quality of the first link is 65 points and the second quality of the second link is 72 points from the point of the packet loss rate, and then the quality difference is |65-72| -7 points.
404. And determining a switching result according to the quality difference, wherein the switching result is used for indicating whether to switch a first link currently used for communication between the first client and the second client to a second link.
In this embodiment, the quality difference is used to determine whether to switch the first link to the second link, i.e. to determine the switching result. The above mentioned handover result comprises two branches, first: the switching result is that the first link is switched to the second link; secondly, the method comprises the following steps: the switching results in the first link not being switched to the second link, mainly because the first link has a negligible quality degradation, and communication can still continue through the first link.
Optionally, in other embodiments, whether to switch the first link is determined by setting a certain preset threshold, which is as follows: when the quality difference is smaller than a preset threshold value, determining a first switching result, wherein the first switching result is used for indicating that the first link is not switched to the second link; and when the quality difference is greater than or equal to the preset threshold, determining a second switching result, wherein the second switching result is used for indicating that the first link is switched to the second link.
In this embodiment, the preset threshold mentioned above may be set by a user according to an actual application situation, and is not specifically limited in this embodiment. For example: assuming that the preset threshold is 10, the difference between the quality of the first link and the quality of the second link is 7 points based on the example described in step 403. Obviously, the quality difference is smaller than the preset threshold, and the switching component determines that the first switching result for switching the first link to the second link is not needed. For another example: assuming that the preset threshold is 5, based on the example described in step 403, the quality difference between the first link and the second link is 7 minutes, and obviously the quality difference is greater than the preset threshold, then the switching component needs to switch the first link to the second link, so that the first client and the second client seamlessly switch from the first link to the second link in the link layer, thereby realizing communication between the two ends through the second link.
Optionally, in other embodiments, to ensure the reasonability of the handover and avoid blind handover, before determining the second handover result, a second probe packet of the first link may be further obtained within the preset time duration, where the second probe packet carries third detection information; detecting the speed and the frequency of the second probe packet in the first link according to the third detection information; and if the speed and the frequency do not meet preset conditions, determining that the quality difference is greater than or equal to the preset threshold.
In this embodiment, a second probe packet of a first link is obtained, and third detection information carried in the second probe packet is analyzed from the second probe packet, so as to detect a transmission speed and a frequency of the second probe packet in the first link, and if the transmission speed and the frequency do not satisfy a preset condition, that is, are lower than a threshold set by a user, it is largely indicated that the first quality of the first link is poor, at this time, a switching component may determine that a quality difference between the first quality of the first link and the second quality of the second link is greater than or equal to the preset threshold, at this time, the switching component needs to switch the first link to the second link, so that a seamless transition from the first link to the second link is performed between a first client and a second client in a link layer, and communication between the two ends is achieved through the second link.
In the embodiment of the application, the first link and the second link are deployed in a link layer, so that after monitoring the first quality of the first link and the second quality of the second link within a preset time, the switching component determines a quality difference between the first quality and the second quality, and determines a switching result for indicating whether to switch the first link currently used for communication between the first client and the second client to the second link according to the quality difference. Therefore, in the communication process after the network environment changes, the communication link is seamlessly switched on the link layer through the switching component, so that the communication can be continued without reestablishing the communication link as in the application layer, the bandwidth cost in the communication process is reduced, and the user experience is improved.
