Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
The embodiment of the invention provides a message transmission method, which is applied to a switching device in wireless communication equipment, wherein the switching device is used for transmitting a message to a central processing unit in the wireless communication equipment. Fig. 2 is a first flowchart of a message transmission method according to an embodiment of the present invention. As shown in fig. 2, the method mainly comprises the following steps:
s201, receiving at least one message.
In an embodiment of the invention, the switching device may receive at least one message.
It should be noted that, in the embodiment of the present invention, the switching device in the wireless communication device is provided with at least one external network port, and the switching device may receive at least one message through the at least one external network port. The specific number of external ports is not limited in the embodiments of the present invention.
It should be noted that, in the embodiment of the present invention, at least one message received by the switching device may be received from one external network port, or may be received from different external network ports. The embodiment of the present invention is not limited to a specific network port for receiving a message and a specific message.
It should be noted that, in the embodiment of the present invention, the wireless communication device may be a wireless base station device, and the embodiment of the present invention is not limited.
It should be noted that, in the embodiment of the present invention, at least one message received by the switching device originates from an external transmission network, and the switching device may receive, through an external network port, a message transmitted by the transmission network through the ethernet network.
It should be noted that, in the embodiment of the present invention, the wireless communication device may be deployed in a remote area, and therefore, a message received by the switch device through the external network port may be a layer two-broadcast message or a layer three User Datagram Protocol (UDP) unicast message, which is not limited in the embodiment of the present invention.
S202, extracting at least one type representation information from at least one message.
In the embodiment of the present invention, after receiving at least one message through the external network port, the switching apparatus may extract at least one type characterizing information from the at least one message.
It can be understood that, in the embodiment of the present invention, each of the at least one message received by the switching apparatus includes the type characterizing information, so that the switching apparatus may directly extract the corresponding type characterizing information from each message, that is, extract at least one type characterizing information from the at least one message. The specific type characterizing information is not limited in the embodiments of the present invention.
Optionally, in this embodiment of the present invention, the type characterizing information may be a Media Access Control (MAC) address, or an ethernet protocol type and source port information.
For example, in the embodiment of the present invention, the type characterizing information is a destination physical address, and the switching device may directly extract at least one destination physical address from at least one message, that is, the switching device extracts a destination physical address corresponding to each message from each message.
For example, in the embodiment of the present invention, the type characterizing information is an ethernet protocol type and source port information, and the switching device may directly extract at least one ethernet protocol type and at least one source port information from at least one packet, that is, the switching device extracts the ethernet protocol type and the source port information corresponding to each packet from each packet.
S203, according to the at least one type representation information, determining a clock message with the message type being the clock type from the at least one message, and acquiring receiving port information corresponding to the clock message.
In the embodiment of the present invention, after extracting at least one type characterizing information from at least one message, the switching apparatus may determine, according to the at least one type characterizing information, a clock message whose message type is a clock type from the at least one message, and obtain receiving port information corresponding to the clock message.
It can be understood that, in the embodiment of the present invention, the switching apparatus may extract different type representation information, and therefore, the clock packet whose packet type is the clock type may be determined from at least one packet according to different methods.
Specifically, in the embodiment of the present invention, the type characterizing information is a destination physical address, the switching device matches at least one destination physical address corresponding to at least one packet with a preset destination physical address from at least one packet to obtain at least one matching result, and then determines, as a clock packet, a packet corresponding to a destination physical address that is successfully matched from among the at least one matching result.
Illustratively, the switching device receives two messages, namely a first message and a second message, and then extracts a destination physical address corresponding to the first message, namely a first physical address, and extracts a destination physical address corresponding to the second message, namely a second physical address, and matches the first physical address and the second physical address with a preset physical address respectively to obtain a first matching result and a second matching result. And finally, if the first matching result is that the matching is successful, the first message corresponding to the first physical address is a clock message, and if the second matching result is that the matching is successful, the second message corresponding to the second physical address is a clock message.
Specifically, in the embodiment of the present invention, the switching apparatus may further determine, from at least one type characterizing information corresponding to at least one packet, that the ethernet protocol type is a preset type, and the source port information is first type characterizing information of preset source port information, and then determine a packet corresponding to the first type characterizing information as a clock packet.
It is to be understood that, in the embodiment of the present invention, the type characterizing information may include: the ethernet protocol type and the source port information, that is, the type characterizing information corresponding to a packet, may be the ethernet protocol type and the source port information corresponding to the packet, and when the ethernet protocol type is a preset type and the source port information is the preset source port information, that is, the type characterizing information corresponding to the packet is the first type characterizing information, therefore, the switching device determines that the packet is a clock packet.
For example, the switching device receives two messages, which are a first message and a second message, and then extracts an ethernet protocol type corresponding to the first message, that is, the first ethernet protocol type, and source port information corresponding to the first message, that is, first source port information, and extracts an ethernet protocol type corresponding to the second message, that is, the second ethernet protocol type, and source port information corresponding to the second message, that is, second source port information. If the first ethernet protocol type is a preset type and the first source port information is preset source port information, the switching device determines the first ethernet protocol type and the first source port information as first type characterization information, so as to determine the first message as a clock message. Similarly, if the second ethernet protocol type is the preset type and the second source port information is the preset source port information, the switching device determines the second ethernet protocol type and the second source port information as the first type characterizing information, thereby determining the second packet as the clock packet.
Illustratively, the default type is UDP and the default source port information is 319 and 320. The switching device receives the first message, and extracts an ethernet protocol type corresponding to the first message, that is, the first ethernet protocol type, and source port information corresponding to the first message, that is, the first source port information. When the first ethernet protocol type corresponding to the first packet is UDP and the first source port information corresponding to the first packet is 319 or 320, the switching apparatus determines that the packet type of the packet is a clock type and the packet is 1588.
It should be noted that, in the embodiment of the present invention, since the switching device may receive at least one packet, as long as the corresponding type characterization information can characterize that the packet type of the received packet is the clock type, it may be determined that the packet is the clock packet, that is, the number of clock packets may be multiple, as long as the type characterization information satisfies the relevant condition. The specific number of clock messages is not limited in the embodiments of the present invention.
In the embodiment of the present invention, after determining the clock packet, the switching apparatus may also directly obtain the receiving port information corresponding to the clock packet.
It is understood that, in the embodiment of the present invention, since at least one external network port is provided on the switching device, each external network port is configured with a corresponding port number. The switching device may directly obtain the port number of the external network port for receiving the clock packet, that is, the receiving port information corresponding to the clock packet. The embodiment of the present invention is not limited to a specific receiving port information corresponding to the clock packet.
Illustratively, the switching device is provided with 3 external ports, which are respectively a port 1, a port 2, and a port 3, where the port number corresponding to the port 1 is a, the port number corresponding to the port 2 is B, and the port number corresponding to the port 3 is C. The switching device receives the first message through the network port 1 and receives the second message through the network port 3. The first message is determined to be a clock message, and therefore the switching device can directly acquire that the receiving port information corresponding to the first message is a.
S204, sending the clock message and the receiving port information to a central processing unit through a first interface; the first interface is an interface configured to transmit a clock type message in the switching apparatus.
In the embodiment of the present invention, after determining the clock packet and acquiring the receiving port information corresponding to the clock packet, the switching apparatus may send the clock packet and the receiving port information corresponding to the clock packet to the CPU through the first interface.
It can be understood that, in the embodiment of the present invention, for the clock packet, attention needs to be paid to port information of the first port of the switching apparatus, which receives the clock packet. Therefore, after acquiring the receiving port information corresponding to the clock message, the switching device sends the clock message to the CPU and sends the receiving port information corresponding to the clock message to the CPU.
It should be noted that, in the embodiment of the present invention, the switching device is provided with a first interface, and the first interface is an interface configured to transmit the clock type packet in the switching device.
It should be noted that, in the embodiment of the present invention, since an extended Peripheral Component Interconnect (PCIE) interface can simultaneously transmit a message and related information, the first interface may be a (PCIE) interface. The switching device can send the clock message and the receiving port information corresponding to the clock message to the CPU through the PCIE interface.
Specifically, in the embodiment of the present invention, the switching device may generate additional information corresponding to the clock packet according to the clock packet, then write the receiving port information corresponding to the clock packet into the additional information corresponding to the clock packet, and finally send the clock packet and the additional information corresponding to the clock packet to the CPU through the first interface.
It should be noted that, in the embodiment of the present invention, the additional information corresponding to the clock message may be basic information of the clock message, that is, summary information of the clock message. The embodiment of the present invention is not limited to specific additional information of the clock packet.
It can be understood that, in the embodiment of the present invention, the switching device sends the additional information corresponding to the clock packet and the clock packet to the CPU through the first interface, and the CPU can know which external network port receives the clock packet in the switching device is specifically the external network port according to the additional information corresponding to the clock packet, so as to perform subsequent clock protocol processing, for example, select an optimal clock source.
It should be noted that, in the embodiment of the present invention, before the switching device sends the receiving port information and the clock packet corresponding to the clock packet to the CPU through the first interface, since the clock packet is determined to be the clock packet, a clock counter inside the switching device may also be read to obtain the residence time of the clock packet, and then, the residence time of the clock packet is written into a Configuration Field (CF) Field of the clock packet.
It should be noted that, in the embodiment of the present invention, the residence time of the clock packet is actually the time length from when the switching device receives the clock packet to when the switching device sends the clock packet, and the specific residence time of the clock packet is not limited in the embodiment of the present invention.
It can be understood that, in the embodiment of the present invention, the switching device writes the residence time of the clock packet into the configuration field of the clock packet, and when the CPU receives the first packet, the CPU can obtain the residence time of the clock packet by reading the configuration field of the clock packet, so as to perform subsequent clock protocol processing.
It should be noted that, in the embodiment of the present invention, after determining the clock message from at least one message, the switching device also needs to send the message of the non-clock message to the CPU in other manners to perform transmission, and the CPU may perform data transmission without setting a large number of network cards, thereby improving the flexibility of message transmission.
Fig. 3 is a second flowchart of a message transmission method according to an embodiment of the present invention. As shown in fig. 3, after step S203, steps S301 to S302 may be further included, and the specific steps are as follows:
s301, determining a message of a non-clock message in at least one message as a data message with a message type of a data type.
In the embodiment of the present invention, after determining a clock packet from at least one packet, the switching device determines a packet that is not a clock packet in the at least one packet as a data packet whose packet type is a data type.
Illustratively, the switching device receives two messages, which are a first message and a second message, respectively, wherein the first message is determined to be a clock message from the two messages, and therefore, the second message can be directly determined to be a data message.
It should be noted that, in the embodiment of the present invention, since the switching device may receive at least one packet, there may be a plurality of data packets. The specific number of data messages is not limited in the embodiments of the present invention.
S302, sending the data message to a central processing unit through a second interface; the second interface is an interface configured to transmit the data type packet in the switching apparatus.
In an embodiment of the invention, the switching device sends the data packet to the CPU via the second interface after determining the data packet.
It should be noted that, in the embodiment of the present invention, the switching device is provided with a second interface, and the second interface is an interface configured to transmit the data type packet in the switching device. Specific second interface embodiments of the present invention are not limited.
It can be understood that, in the embodiment of the present invention, for the data packet, there is no need to pay attention to the receiving port information corresponding to the receiving data packet in the switching device. The switching device can therefore send data messages to the CPU via the ethernet directly via the second interface. After receiving the data message, the CPU can process the subsequent data message according to the data message.
It should be noted that, in the embodiment of the present invention, the wireless communication device may include a plurality of CPUs. The number of CPUs is not limited in the embodiments of the present invention.
Fig. 4 is a first schematic diagram of exemplary message transmission according to an embodiment of the present invention. As shown in fig. 4, if the wireless communication device only includes one CPU, when a message received by the switch device through the external network interface is a clock message, the switch device may send, to the CPU, receiving port information and the clock message corresponding to the clock message through the first interface, and specifically send the receiving port information and the clock message to a module in the CPU for processing the clock message, where the first interface is a PCIE interface and the channel is a PCIE channel. When the switching device receives the data packet through the external network port, the switching device may send the data packet to the CPU through the second interface, and specifically to a module in the CPU for processing the data packet.
Fig. 5 is a second schematic diagram of exemplary message transmission according to an embodiment of the present invention. As shown in fig. 5, if the CPU includes two CPUs, the two CPUs are a first CPU and a second CPU, respectively, where the first CPU includes a module for processing a clock packet, and the second CPU includes a module for processing a data packet. When the packet received by the switch device through the external network interface is a clock packet, the switch device may specifically send the receiving port information and the clock packet corresponding to the clock packet to the module for processing the clock packet in the first CPU through the first interface, where the first interface is a PCIE interface and the channel is a PCIE channel. When the switching device receives the data packet through the external network port, the switching device may send the data packet to the second CPU through the second interface, and specifically to a module in the second CPU for processing the data packet.
