Abstract

A method and a network device for transmitting a data stream are provided in the embodiments of the present invention. The present invention relates to the field of communications, can ensure the effective transmission of the data stream, and enhances the quality of service of the network. The method for transmitting a data stream includes: determining, according to a forwarding table, candidate forwarding ports for transmitting the data stream; determining, according to a priority level of the data stream and priority levels of the candidate forwarding ports, forwarding ports for transmitting the data stream; transmitting the data stream through a first forwarding port of the forwarding ports; when the first forwarding port is congested, transmitting the data stream through a second forwarding port of the forwarding ports. The embodiments of the present invention can be adopted to transmit the data stream.

Description

technical field [0001] The invention relates to the communication field, in particular to a data flow transmission method and network equipment. Background technique [0002] A traditional IP (Internet Protocol, Internet Protocol) network mainly bears data services, and adopts a best-effort transmission method, so the quality of service is obviously irrelevant. However, with the rapid development of the Internet with IP technology as the core and the emergence of various new services, such as VOIP (Voice over Internet Protocol, Internet telephony), VPN (Virtual Private Network, virtual private network), etc., the IP network has been formed by a simple data The network is transformed into a bearer network with commercial value, so the IP network must provide corresponding quality of service for each type of business it carries. [0003] However, in the prior art, the transmission path of the data flow is fixed. Once the current port is congested, the data flow can only be di...
