However, if user A keeps sending packets with high priority in the virtual network volume, the network switch will instead prioritize the packets sent by user A, and doing so will violate the interests of the network service provider

Embodiment Construction

[0019] FIG. 1 shows an example of a network system 100 including a network switch 106 . The computer hosts 102 and 104 are connected to a network 108 via a network switch 106 . Server 110 is also connected to network 108 . Network switch 106 processes packets from host computers 102 and 104 or packets sent to host computers 102 and 104 from elsewhere. However, due to the limited bandwidth of the network switch 106, if the network switch 106 receives a large number of packets at the same time, it cannot process so many packets at the same time, so the processing order of the packets must be determined first. Because the packet conforming to the IEEE 802.1q protocol will be added with a virtual local area network tag (VLAN tag), which includes a 3-bit packet priority field to indicate the priority of the packet, the network switch 106 can be based on the VLAN tag The priority field is used to determine the processing order of the packet. Of course, the network switch 106 can ...

Abstract

A method for implementing varying service quality grades in a network switch is provided, comprises the steps of: classifying a plurality of users of the network switch into a plurality of service quality grades according to a contributing factor of the plurality of the users; connecting each of the plurality of users to the network switch via one of a plurality of ports of the network switch according to its service quality grade; determining an original priority of a packet in the network switch; and determining an adjusted priority of the packet according to both the original priority of the packet and a priority adjustment table of an ingress port of the packet. Each of the plurality of ports has a corresponding priority adjustment table, and each of the priority adjustment tables includes a mapping relationship between the original priority and the adjusted priority.

Description

technical field [0001] The present invention relates to network communications, and more particularly to network switches. Background technique [0002] Quality of service (QoS) is a specific level of processing performance in a data communication system. When data is divided into multiple packets and transmitted through a network switch (network switch) or router (router) in a local area network (LAN) or wide area network (WAN), often by specifying a specific Priority (priority) method to meet the requirements of a specific quality of service level. These network switches and routers can rely on quality of service mechanisms built into their software to determine which packets can be prioritized for processing. The quality of service mechanism may determine the priority of packets based on attributes of a packet, or on the level of service granted to the sender of the packet based on corporate policy. For example, packets used for VoIP use require high processing speed t...
