Embodiment 1

[0060] The embodiment of the present invention provides a detection method in a virtual local area network, see figure 1 , the method includes:

[0061] 101. Obtain the target Internet Protocol IP address of the user machine;

[0062] 102. Search the target IP address in the user trust table; the virtual local area network VLAN and the IP address corresponding to the preserved VLAN are stored in the user trust table; wherein, the VLAN stored in the user trust table is specifically represented by a VLAN identification form Yes, the VLAN identifier can uniquely identify the corresponding VLAN, and a VLAN corresponds to a VLAN identifier.

[0063] 103. When the target IP address is found in the user trust table, send a detection packet to the VLAN corresponding to the target IP address. Wherein, there may be one or more VLANs corresponding to the target IP address, and when the target IP address is found in the user trust table to correspond to multiple VLAN IDs, a detection re...

Embodiment 2

[0083] The embodiment of the present invention provides a detection method in a virtual local area network, see figure 2 , the method includes:

[0084] 201. Establish a user trust table, the user trust table saves the VLAN and the IP address corresponding to the saved VLAN;

[0085] Concretely, at first need set up user's trust table, save the IP address corresponding to VLAN and described preserved VLAN in this user's trust table before obtaining, wherein, the VLAN that preserves in the user's trust table specifically expresses VLAN with VLAN identification form, The VLAN identifier can uniquely identify the corresponding VLAN, and one VLAN corresponds to one VLAN identifier.

[0086] Wherein, the manner of obtaining the VLAN and the IP address corresponding to the saved VLAN includes but not limited to the following 1-3:

[0087] 1. Obtain the IP address and the corresponding VLAN when receiving the detection message; here, receiving the detection message can be actively...

Embodiment 3

[0119] see image 3 , an embodiment of the present invention provides a detection device in a virtual local area network, see image 3 , the device consists of:

[0120] An acquisition module 301, configured to acquire the target Internet Protocol IP address of the user machine;

[0121] Finding module 302, is used for searching target IP address in user's trust table; Save virtual local area network VLAN and the IP address corresponding to the VLAN of described preservation in user's trust table;

[0122] The first detection module 303 is configured to send a detection message to the VLAN corresponding to the target IP address when the target IP address is found in the user trust table.

[0123] Optionally, see Figure 4 , the device may also include:

[0124] The second detection module 304 is used for finding the target IP address when the search module 302 does not find the target IP address in the user trust table, searching for the nearest neighbor IP address with th...

Abstract

A detection method in a virtual local area network comprises the following steps of: obtaining the target network IP (Internet Protocol) address of a user machine; looking up the target IP address in a user trust table, wherein virtual local area networks (VLANs) and IP addresses corresponding to the stored VLANs are stored in the user trust table; and when the target IP address is found in the user trust table, sending a detection message to the VLAN corresponding to the IP address. The method solves the problem of low user access speed under the conditions of batch access of lots of users, frequency access and quit of the users and jittering of network links caused by one-by-one traverse in detection on a QinQ interface or Supervlan interface by looking up the VLAN corresponding to the target IP address in the user trust table and sending out the detection message; and therefore, the equipment load is reduced and the network bandwidth is saved, and the use experience of the users is enhanced.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a detection method, device and equipment in a virtual local area network. Background technique [0002] With the wide application of VLAN (Virtual Local Area Network, virtual local area network), in order to expand the space of VLAN and save IP (Internet Protocol, Internet Protocol) address resources, currently commonly used VLAN mainly includes: QinQ (802.1Q-in- 802.1Q) and SuperVLAN. QinQ adds a layer of public network 802.1Q labels on the basis of 802.1Q packets, expands the VLAN space, increases the number of VLANs to 4094×4094, and enables VLANs to be transparently transmitted to the public network. SuperVLAN, also known as VLAN aggregation, includes Super-VLAN and Sub-VLAN; Super-VLAN only establishes a layer-3 interface for external communication without including physical ports, so that Sub-VLAN can transmit data with the outside through the layer-3 interface; Sub-VL...
