Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application and in the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the application provides a traffic processing method, which is applied to the field of communication, and can ensure that service traffic is accurately forwarded to corresponding master equipment when user equipment comprises the master equipment and slave equipment, thereby improving communication efficiency.
Referring to fig. 1, a schematic structural diagram of a communication system provided in this embodiment of the present application is provided, where the communication system includes a switching device 10 and a user device 20, the user device includes a first user device 201 and a second user device 202, one end of the switching device 10 is communicatively connected to a base station, the other end of the switching device 10 is respectively connected to the first user device 201 and the second user device 202, and the first user device 201 and the second user device are configured with the same network address and can both transmit a target packet with the switching device 10. The target message representation can interact aggregation information of the user equipment and the switching equipment so that the user equipment and the switching equipment can agree on the knowledge of communication link aggregation based on the aggregation information, namely, after the switching equipment successfully transmits the target message with the user equipment, the switching equipment can determine whether a communication link between the switching equipment and the user equipment is normal or not, and if the communication link is normal, the switching equipment can be used for subsequent transmission of target traffic, wherein the target traffic refers to traffic data needing to be transmitted between a base station and the user equipment. The target message is a message which can be generated based on a corresponding communication protocol, so that the transmitting double-side can determine whether the transmission link is normal or not based on the target message, for example, the target message is a message generated based on an LACP (Link Aggregation Control Protocol ), the LACP protocol is divided into a dynamic mode and a static mode, the dynamic mode mainly uses LACP protocol protection interaction judgment to detect the state of the link, and the static mode mainly judges the state of the link through whether a port is opened or not. Thus, the status of the communication link may be determined by the user equipment transmitting the target message with the switching device based on the knowledge of the aggregation of the communication links by the aggregation information.
The first user equipment can be a master device, the second user equipment can be a slave device of the first user equipment, and the first user equipment and the second user equipment have the same network address, so that no matter the first user equipment or the second user equipment is working, the address resolution protocol is unchanged for a base station or a switching device, and no network address drift phenomenon occurs for the switching device.
Correspondingly, referring to fig. 2, a flow chart of a flow processing method provided in an embodiment of the present application may include the following steps:
s201, if the communication link between the first user equipment and the first user equipment is determined to be normal based on the target message transmitted by the first user equipment, transmitting target flow data to the first user equipment.
S202, if the communication link between the first user equipment and the second user equipment is abnormal, transmitting the target flow data to the second user equipment.
When the switching device and the first user device transmit the target message, the first user device may be a target message receiving end or a target message transmitting end. When the first user equipment is used as a sending end of the target message, and the switching equipment is used as a receiving end of the target message, after receiving the target message sent by the first user equipment, the switching equipment analyzes the target message to obtain communication link aggregation information corresponding to the target message, and if the knowledge of the communication link aggregation based on the aggregation information agrees, the communication link between the first user equipment and the second user equipment is normal, the target flow data sent by the base station can be transmitted to the first user equipment. If the analysis result shows that the communication link between the two is abnormal, the method switches to the standby equipment of the first user equipment, namely the second user equipment, and transmits the target flow data to the second user equipment.
In order to facilitate the switching between the first user equipment and the second user equipment, in the embodiment of the present application, the state of a communication link between the first user equipment and the second user equipment is determined by the switching device, and the transmission of the target traffic data is performed based on a normal communication link. In one implementation manner in this embodiment of the present application, the switching device includes at least a first link interface and a second link interface, where the first link interface is configured to be communicatively connected to the first user equipment, and the second link port is configured to be communicatively connected to the second user equipment, and when the first link interface is in an operational state, the second link interface is in a non-operational state. This may enable the switching device to automatically forward traffic data based on the state of the link interface. Thus, the method further comprises: and if the communication link between the first user equipment and the first link interface is abnormal, switching the first link interface from the running state to the non-running state, and switching the second link interface from the non-running state to the running state.
The link interfaces corresponding to the running state representation are opened, and the link states corresponding to the non-running state representation are closed. The link state is determined through the target message transmitted between the switching equipment and the user equipment, so that the corresponding interface state is controlled, the corresponding link state can be determined after the corresponding interface state is detected later, and the transmission of the flow data is more accurately carried out. For example, the first link interface and the second link interface may be LACP ports, which are configured, and the switching device includes a plurality of ports for inputting and/or outputting traffic data to the user device. In practical application, the state of each LACP link of the current device can be determined according to the current state of the LACP port, and when the state of the LACP port is detected to be in a closed state, it is indicated that the LACP link corresponding to the port has a fault, and the transmission of traffic data cannot be performed through the link.
In the embodiment of the application, before transmitting the target traffic data, whether the communication link between the switching device and the user equipment is normal or not can be determined by transmitting the target message between the switching device and the user equipment. If the receiving duration is exceeded, it is indicated that the target message cannot be received normally, i.e. the communication link is abnormal. Correspondingly, in an embodiment, the determining that the communication link with the first user equipment is normal based on the target message transmitted with the first user equipment includes: if the first user equipment sends the target message to the switching equipment, determining whether the target message is received within a target duration; and if so, determining that the communication link with the first user equipment is normal.
Further, switching the first link interface from the operational state to the non-operational state includes: if the target message sent by the first user equipment is not received within the target time, switching the first link interface from the running state to the waiting state; switching the second link interface from the non-operation state to the operation state, and transmitting the target message to the second user equipment through the second link interface; and if the second user equipment receives the target message within the target time, switching the first link interface from a waiting state to a non-running state. When the time for transmitting the target message with the first user equipment is over, the corresponding interface state enters a waiting state, such as waiting for whether the target message can be received or not for a period of time. And transmitting a target message through the second link interface, if the target message is successfully transmitted through the second link interface in the target time length, determining the state of the second link interface as an operation state, and switching the first link interface from a waiting state to a non-operation state at the moment.
Because the network addresses of the first user equipment and the second user equipment are the same, after knowing the network addresses, the target traffic data can be transmitted to the corresponding first user equipment or second user equipment. In one embodiment, the transmitting the target traffic data to the first user equipment includes:
resolving and obtaining a network address of the first user equipment;
transmitting the network address to the base station, so that the base station transmits target traffic data to the first user equipment based on the network address.
Wherein transmitting the target traffic data to a second user equipment comprises: the base station transmits target traffic data to a second user device based on the network address.
In order to ensure the accuracy and efficiency of data transmission, the state of each link can be circularly detected, and the state of the corresponding interface is switched, so that the subsequent flow data transmission is facilitated. In one embodiment, the method further comprises:
circularly detecting a second link interface in an operation state;
and if the detection result shows that the target message sent by the first user equipment connected based on the second link interface is not received within the target time, switching the second link interface from the running state to the non-running state.
The status of the various interfaces may be checked in a round robin fashion to match the more accurate status for each interface. For example, when the second link interface is currently in an operation state, if the transmission of the target message through the second link interface is overtime in the next detection period, the operation state of the second link interface is switched to a non-operation state.
Referring to fig. 3, a schematic diagram of a communication scenario is provided in an embodiment of the present application. In the communication scenario in fig. 3 is a primary and backup UPF (user plane function) device scenario, where one UPF is a primary user equipment and the other is a backup user equipment, traffic data needs to be transmitted between the base station and the user equipment. In fig. 3, the switch device is denoted by SW, the primary user device is denoted by upf, the standby user device is denoted by upf, and the link state is determined between the switch device SW and the user device by LACP (link aggregation control protocol) transmission messages.
Specifically, the LACP aggregation interface is opened on the switch device SW, and the opposite end of the LACP is simulated on upf. Only the master upf interacts LACP protocol messages with the switching device, and only one of the 2 member interfaces of the switching device, which is the interface corresponding to the master upf, enters an operational state, and at this time, traffic is sent to the master upf. When the main upf fails, the interface that interacts with the main upf will timeout to enter a waiting state, and upf from the other interface (i.e. the standby upf interface) will start interacting with the LACP protocol, so that the switching device switches the standby upf interface from the non-operating state to the operating state, and the base station forwards the traffic to the standby upf. Wherein both upf use the same LACP system identification Information (ID) and priority and the interface uses the same network address including an IP address (InternetProtocol Address ) and a MAC address (MediaAccess ControlAddress, media access control address).
Since the interfaces of the two user devices are configured with exactly the same IP address and will use exactly the same mac address, whether the primary or backup upf is in operation, the address resolution protocol (ARP, address ResolutionProtocol) is constant for the base station or gateway and no mac address drift occurs for the switching device at both interfaces. And the accuracy of flow data transmission is improved.
