Embodiment 1

[0068] Embodiment 1 is that the DHCP anchor point at one end detects the state of the opposite end anchor point through a two-way message, that is, by sending a detection request message and receiving a detection response message to detect the state of the opposite end anchor point, which can be called single-ended two-way detection. Figure 4 For the specific flow chart, Figure 5 The schematic diagram of the corresponding process includes the following steps:

[0069] Step 1: The user terminal accesses the network through DHCP, and establishes a DHCP access connection session;

[0070] The user terminal obtains the right to access the network through the access authentication by using the DHCP, and / or obtains the network configuration parameters including the network address by using the DHCP.

[0071] Step 2: The DHCP anchor with the survival mechanism detects that the user terminal has completed access to the network through DHCP (after the access connection session is es...

Embodiment 2

[0084] Embodiment 2 is that the receiver’s DHCP anchor judges the status of the peer end by receiving the sender’s anchor detection message, which can be called single-ended unidirectional detection. After the detection message of the anchor point of the party, if it is judged that the detection message is valid, indicating that the state of the anchor point of the sender is online, the T3 duration indication is set, and the next round of detection is continued. Specific steps such as Figure 6 As shown, the corresponding schematic diagram of the process is shown in Figure 7 shown, including the following steps:

[0085] Step 1: The user terminal accesses the network through DHCP, and establishes an access connection session;

[0086] The user terminal obtains the right to access the network through the access authentication by using the DHCP, and / or obtains the network configuration parameters including the network address by using the DHCP.

[0087] Step 2: The first anc...

Embodiment 3

[0099] Embodiment 3 is a method for both ends to mutually confirm the state of the opposite end. By combining Embodiment 1 and Embodiment 2, after one end receives the other end detection request message, if the message is valid, it can be determined that the other end is online, then Sending a detection response message, after the other end receives the detection response message, if the message is valid, it can determine that the end that sent the response message is online, which can be called double-ended one-way detection. The specific steps are not repeated here.

Abstract

The embodiment of the invention provides a stateful inspection method of a dynamic host configuration protocol. A first anchor point of the dynamic host configuration protocol monitors stateful inspection information sent by a second anchor point within an appointed time; the first anchor point determines the state of the second anchor point according to a monitoring result. The embodiment of the invention also provides a stateful inspection device of a dynamic host configuration protocol, and a system thereof. The embodiment of the invention realizes the maintenance management of accessed and connected calls so as to ensure that the reasonable operations of accounting and management can be carried out, thereby enlarging the application context, mode and range of DHCP.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a state detection method, device and system of a dynamic host configuration protocol. Background technique [0002] Dynamic Host Configuration Protocol (DHCP) provides a mechanism for dynamically specifying IP addresses and configuration parameters, and is mainly used in large-scale network environments and places where configuration is difficult. According to this agreement, the DHCP server will automatically specify the IP address and configuration parameters for the client. The specified configuration parameters may not be related to the IP protocol, but because the configuration process of DHCP can be automatically realized, all configuration information can be provided by the DHCP server. Unified management can not only assign IP addresses, but also configure a large amount of other information. These configuration parameters make computer communication on the network...
