Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of them.
Fig. 1 is a flowchart of a network address setting method provided in an embodiment of the present application, which is applicable to a case of configuring a network address of a terminal device, where the method may be executed by the terminal device provided in the embodiment of the present application, and a network address setting apparatus of the terminal device may be implemented in a software and/or hardware manner, as shown in fig. 1, a specific scheme provided in this embodiment is as follows:
and step S101, receiving the data broadcast packet sent by the configurator.
The configurator has a DHCP function, and may be a specially configured DHCP (Dynamic Host configuration Protocol) server, or may be a routing device integrated with the DHCP function.
In the prior art, a terminal device needs to have its own network address during communication with other terminal devices or servers when accessing the internet, and a configurator allocates the network address to the accessed terminal device. Specifically, the terminal device performs TCP/IP initialization, sends a DHCP Discover broadcast packet to the network through a UDP port, and a corresponding configurator having a function of providing a network address responds to the DHCP Discover broadcast packet, and sends a DHCP REQUEST message packet, and the configurator confirms the network address assigned to the terminal device and sends a DHCP ACK message packet. This existing mode is prone to cause the configurator to assign to network addresses that are not available to the terminal device, resulting in abnormal network access by the terminal device.
In this step, a data broadcast packet sent by the configurator is received, the data broadcast packet is generated by the configurator according to the dynamic host configuration protocol, and correspondingly, before the configurator sends the data broadcast packet, a Discover broadcast packet sent by the terminal device is received to respond to the data broadcast packet. The dynamic host configuration protocol is a standard protocol defined to allow dynamic assignment of IP addresses and configuration information to terminal devices.
Step S102, analyzing the data broadcast packet, and determining network address information carried in the data broadcast packet.
The data broadcast packet may be a DHCP Offer broadcast packet, and after being analyzed, the data broadcast packet determines network address information carried by the broadcast packet according to the analysis data, where the network address information includes a currently allocated network address, a gateway address, and a subnet mask, and for example, an analysis result of the network address information part is:
Your client IP address:x.x.x.x
Subnet Mask:x.x.x.x
Gateway:x.x.x.x
step S103, determining whether the currently allocated network address is available according to the network address information, if not, sending a rejection message, and re-determining the network address.
In this step, it is directly determined whether the currently allocated network address is available according to the network address information determined by parsing in step S102, in an embodiment, the determined network address information includes the currently allocated network address, a gateway address, and a subnet mask, and correspondingly, determining whether the currently allocated network address is available includes: determining a broadcast address of a local area network according to the gateway address and the subnet mask, wherein the specific determination mode is as follows: bitwise negating the subnet mask in the determined network address information, and bitwise OR operation is carried out on the obtained result and the gateway address; and judging whether the currently allocated network address is the same as the broadcast address or not, and if so, sending a rejection message. The broadcast address is an address specially used for sending data packets to all access points in the network at the same time, and the reject message may be a DHCP Decline broadcast packet. The rejection message carries the currently allocated network address which cannot be used, so that the configurator records the network address and does not distribute the unavailable network address for the second time, and after the rejection message is sent out, the network address is correspondingly and immediately determined again.
As can be seen from the above, whether the current network address is available is determined according to the analyzed network address information by analyzing the received data broadcast packet sent by the configurator, and if not, the new network address is immediately re-determined.
Fig. 2 is a flowchart of another network address setting method provided in an embodiment of the present application, where optionally, the network address information includes a currently allocated network address and a gateway address, and correspondingly, determining whether the currently allocated network address is available according to the network address information, and if not, sending a rejection message includes: and judging whether the currently allocated network address is the same as the gateway address or not, and if so, sending a rejection message. As shown in fig. 2, the technical solution is as follows:
step S201, receiving a data broadcast packet sent by the configurator.
Step S202, analyzing the data broadcast packet, and determining a currently allocated network address and a gateway address carried in the data broadcast packet.
The network address information obtained by analysis comprises the currently allocated network address and the gateway address.
Step S203, determining whether the currently allocated network address is the same as the gateway address, if so, executing step S204, and if not, executing step S205.
If the network address is the same as the gateway address, the terminal device is abnormal in surfing the internet and cannot communicate with the network.
Step S204, sending a rejection message, and re-determining the network address.
And step S205, sending a response message to receive the currently allocated network address.
The configurator may send an acknowledgement message (DHCP Ack broadcast packet) after receiving the response message, and use the network address allocated to the terminal device.
According to the method, the received data broadcast packet sent by the configurator is analyzed, whether the currently allocated network address is consistent with the gateway address is judged according to the analyzed network address information, if so, the new network address is immediately determined again, the problems that the network cannot be accessed and the network connection is abnormal due to unavailable network addresses are avoided, and the network address allocation flow is optimized.
Fig. 3 is a flowchart of another network address setting method provided in an embodiment of the present application, and optionally, the determining whether a currently allocated network address is available according to the network address information, and if not, sending a rejection message further includes: and judging whether the currently allocated network address conflicts with the network addresses of other equipment or not, and if so, sending a rejection message. As shown in fig. 3, the technical solution is as follows:
step S301, receiving the data broadcast packet sent by the configurator.
Step S302, the data broadcast packet is analyzed, and the currently allocated network address, the gateway address and the subnet mask carried in the data broadcast packet are determined.
Step S303, determining a broadcast address according to the gateway address and the subnet mask.
Step S304, judging whether the broadcast address is the same as the currently allocated network address, if so, executing step S306, and if not, executing step S305.
Step S305, judging whether the currently allocated network address conflicts with the network addresses of other devices, if so, executing step S306, and if not, executing step S307.
Optionally, when performing network address conflict detection, the terminal device may send an ARP packet to the currently allocated network address, and determine whether the currently allocated network address conflicts with network addresses of other devices according to the feedback result, for example, if the feedback result is detected, it is proved that other hosts use the currently classified network address, and the network address conflicts are determined, otherwise, it is determined that the network address does not conflict with other devices.
Step S306, sending a rejection message, and re-determining the network address.
Step S307, sending a response message to receive the currently allocated network address.
Therefore, under the condition that the broadcast address is determined to be inconsistent with the currently allocated network address according to the received network address information, whether the currently allocated network address is occupied by other equipment is further detected, and if the currently allocated network address is occupied, a rejection message is sent to re-determine the network address, so that the terminal equipment can avoid the problem of network address conflict.
Fig. 4 is a flowchart of another network address setting method provided in an embodiment of the present application, where optionally, the re-determining a network address includes: generating a network correction address according to the currently allocated network address and a preset rule; and sending the network correction address to the configurator for configuration. As shown in fig. 4, the technical solution is as follows:
step S401, receiving the data broadcast packet sent by the configurator.
Step S402, analyzing the data broadcast packet, and determining a currently allocated network address, a gateway address and a subnet mask carried in the data broadcast packet.
Step S403, determining a broadcast address according to the gateway address and the subnet mask.
Step S404, judging whether the broadcast address is the same as the currently allocated network address, if so, executing step S406, and if not, executing step S405.
Step S405, judging whether the currently allocated network address conflicts with the network addresses of other devices, if so, executing step S406, and if not, executing step S407.
Step S406, sending a rejection message, generating a network correction address according to the currently allocated network address and a preset rule, and sending the network correction address to the configurator for configuration.
The preset rule may be that 1 is added or 1 is subtracted at the end of the determined currently allocated unavailable network address to serve as a network correction address, and after the network correction address is sent to the configurator, the configurator determines the network correction address correspondingly.
In one embodiment, after determining the network correction address, the terminal device performs conflict detection on the network correction address, sends the network correction address to the configurator if no address conflict is detected, and continues to perform correction until no conflict exists if an address conflict is detected.
Step S407, sending a response message to receive the currently allocated network address.
Therefore, when the currently allocated network address is unavailable, the terminal device can correct and update the network address by itself and send the corrected network address to the configurator for confirmation, and if the corrected network address is available, the terminal device determines the corrected network address as the final network address, so that the problem of low efficiency caused by repeated application is solved.
Fig. 5 is a block diagram of a network address setting device according to an embodiment of the present application, where the device is configured to execute the network address setting method according to the foregoing embodiment, and has functional modules and beneficial effects corresponding to the execution method. As shown in fig. 5, the apparatus specifically includes: a receiving module 101, a parsing module 102 and a configuration module 103, wherein,
the receiving module 101 is configured to receive a data broadcast packet sent by a configurator, where the data broadcast packet is generated by the configurator according to a dynamic host configuration protocol.
The configurator has a DHCP function, and may be a specially configured DHCP (Dynamic Host configuration Protocol) server, or may be a routing device integrated with the DHCP function.
In this step, a data broadcast packet sent by the configurator is received, the data broadcast packet is generated by the configurator according to the dynamic host configuration protocol, and correspondingly, before the configurator sends the data broadcast packet, a Discover broadcast packet sent by the terminal device is received to respond to the data broadcast packet. The dynamic host configuration protocol is a standard protocol defined to allow dynamic assignment of IP addresses and configuration information to terminal devices.
And the analysis module 102 is configured to analyze the data broadcast packet and determine network address information carried in the data broadcast packet.
The data broadcast packet may be a DHCP Offer broadcast packet, and after being analyzed, the data broadcast packet determines network address information carried by the broadcast packet according to the analysis data, where the network address information includes a currently allocated network address, a gateway address, and a subnet mask, and for example, an analysis result of the network address information part is:
Your client IP address:x.x.x.x
Subnet Mask:x.x.x.x
Gateway:x.x.x.x
a configuration module 103, configured to determine whether the currently allocated network address is available according to the network address information, and if not, send a rejection message and re-determine the network address.
Determining whether the currently allocated network address is available directly according to the determined network address information analyzed by the analyzing module 102, in an embodiment, the determined network address information includes the currently allocated network address, a gateway address, and a subnet mask, and accordingly, determining whether the currently allocated network address is available includes: determining a broadcast address of a local area network according to the gateway address and the subnet mask, wherein the specific determination mode is as follows: bitwise negating the subnet mask in the determined network address information, and bitwise OR operation is carried out on the obtained result and the gateway address; and judging whether the currently allocated network address is the same as the broadcast address or not, and if so, sending a rejection message. The broadcast address refers to an address specially used for sending data packets to all access points in the network at the same time, and the reject message may be a DHCP Decline broadcast packet. The reject message carries the currently allocated unusable network address, so that the configurator records the unusable network address and does not distribute the unusable network address for the second time, and the network address is re-determined immediately after the reject message is sent out.
As can be seen from the above, whether the current network address is available is determined according to the analyzed network address information by analyzing the received data broadcast packet sent by the configurator, and if not, the new network address is immediately re-determined.
