Embodiment Construction

[0020] The first embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Such as figure 2 As shown, the QoS control device based on VLAN ID according to the first embodiment of the present invention includes: an ingress unit 21 for inputting packet data and transmitting it to a classification unit; a classification unit 22 for checking packets transmitted from the ingress unit Whether to have mark, if not, then add default mark to it, if have mark, then use the VLAN ID of mark to confirm the broadcast scope of grouping; Be used for the address table storage unit 23 of storing address table; Processing unit 24, use Based on address learning, the virtual network identifier is extracted from the packet, the control entry is read from the control table storage unit 25 according to the virtual network identifier, and the corresponding quality of service control is applied to the packet, and then the packet is forwarded to ...

Abstract

The method includes following steps: packet with tag arrives to exchanger; device checks whether the source address of the packet is learned or not; if not, step of learning address is carried out, a address item is formed in the address list; otherwise, matching destination address of the packet is carried out; determining whether a address item is found or not; if yes, based on VLAN ID corresponding control item of service quality is searched; control of service quality is implemented for the packet, which is transmitted from the corresponding port; if no address item is found, based on VLAN ID, corresponding port set is found, then the packet is flooded. The invention can apply service quality control for specific user group, as well as control service quality for multiple groups of possessing the same need by a service-controlling rule.

Description

technical field [0001] The present invention relates to the Ethernet switching control process based on IEEE802.3, in particular, the present invention relates to a device and method for controlling quality of service through the VLAN ID (virtual network identification) carried in the IEEE802.1q tag during the switching process . Background technique [0002] At present, virtual local area network (Virtual Local Area Networks-VLAN) technology develops very rapidly. VLAN is a local area network that is logically divided on the physical network according to purpose, working group and application, and is a broadcast network. In 1999, IEEE promulgated the 802.1Q protocol standard draft to standardize VLAN implementation. This makes the intercommunication of VLANs between different vendors possible. A new Ethernet field is specified in the protocol, that is, a 4-byte 802.1Q tag is added after the source address in the VLAN message format. In the four-byte 802.1Q tag, it inclu...
