Embodiment 1

[0069] There is data in the incoming direction, single-layer VLAN 100, priority 1, needs to be converted to 200, priority converted to 3, priority of other data is uniformly converted to 0, VLAN ID does not change. Can be parsed into the following tuples:

[0070] Direction: IN;

[0071] Filter: SINGLE_TAG_100_PRIO_1;

[0072] Action: VLAN switch 200_priority switch 3;

[0073] Direction: IN;

[0074] Filter: SINGLE_TAG_DEFAULT;

[0075] Action: Priority transition_0.

Embodiment 2

[0077] There is a data distribution direction, the number of VLAN layers is 2, the outer VLAN is 100, the inner VLAN is 300, the inner priority is 5, the outer priority is 1, the outer VLAN needs to be deleted, and the inner VLAN needs to be converted to 500 , it is necessary to change the inner priority to 0, the other 2 VLANs only transparently transmit the outer priority 7, and the lower priority is discarded. Can be parsed into the following tuples:

[0078] Direction: OUT;

[0079] filter:;

[0080] DOUBLE_TAG_OUTER_TAG_100_PRIO_1_INNER_TAG_300_PRIO_5;

[0081] Action: DELETE_OUTER VLAN_TRANSFER_INNER VLAN_500_TRANSFER INNER PRIORITY_0;

[0082] Direction: OUT;

[0083] Filter: DOUBLE_TAG_DEFAULT_OUTER_PRIO_7;

[0084] Action: transparent transmission;

[0085] Direction: OUT;

[0086] Filter: DOUBLE_TAG_DEFAULT;

[0087] Action: Discard.

Abstract

The invention relates to a method for realizing unified analysis and processing of VLAN services, which comprises the following steps: configuring the frame of VLAN service analysis according to the device type; configuring the direction of VLAN data according to the configuration analysis; filtering the VLAN data; and performing filtering on the filtered VLAN data. Action processing; transmit the analysis results of VLAN data and perform subsequent processing. The method for realizing the unified analysis and processing of VLAN services of the present invention is adopted, so that the software can be analyzed uniformly when processing VLAN services, and saved in a unified manner to reduce development time. The software of the same manufacturer can even be developed and processed in a unified manner on different types of data devices through the invention. , which avoids the confusion of VLAN service definitions caused by multiple standards of different equipment manufacturers, and has a wide range of applications.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to the field of virtual local area network, and specifically refers to a method for realizing unified analysis and processing of VLAN services. Background technique [0002] In the field of communication technology, VLAN is an important technology. VLAN (Virtual Local Area Network) is a logical segment of network users connected to the port of the second-layer switch. Segmentation. A VLAN can be implemented on a switch or across switches. VLANs can be grouped according to the location, role, or department of network users, or according to the applications and protocols used by network users. Switch-based virtual local area network can solve conflict domain, broadcast domain and bandwidth problems for local area network. [0003] Common forms of VLAN include no VLAN tag, single-layer VLAN tag, QINQ (double-layer VLAN tag), etc. After the data stream passes through a data c...
