Method, system, apparatus for control transmission priority and user network edge equipment

Abstract

The invention provides a method for controlling transmission priority, a system, a device and user network edge equipment thereof, wherein, the method comprises: one or a plurality of pieces of equipment in multi-protocol label switching (MPLS) core network is collocated with the corresponding relation between routing information and quality of service (QoS) in advance; when the equipment confirms that certain routing information satisfies the condition for releasing QoS information, the QoS information of the routing information is obtained from the corresponding relation, and the routing information and the QoS information of the routing information are forwarded by hop-to-hop to the user network edge (CE equipment) in the user network; the CE equipment receives the routing information and the QoS information of the routing information, when the routing information is used for transmitting the service flow, the IP message head of the service flow carries the IP priority information which the QoS information is corresponding to. The invention leads to simpler collocation and maintenance work and lowers the cost of the collocation and maintenance work.

Description

Technical field [0001] The present invention relates to the field of network communication, and in particular to a method, system device and user network edge equipment for controlling transmission priority. Background technique [0002] Multiprotocol Label Switching (MPLS, Multiprotocol Label Switching)-based Layer 3 Virtual Private Network (VPN, Virtual Private Network) is a type of MPLS technology, which uses Border Gateway Routing Protocol (BGP) to publish in the service provider network Routing, using MPLS to control the priority used for forwarding traffic in the service provider network. [0003] figure 1 It is the network structure diagram of the third layer VPN of MPLS in the prior art, such as figure 1 As shown, the network mainly includes three types of equipment: Customer Edge (CE) equipment located in the customer network, and Provider Edge (PE) routers and backbone (P, Provider) equipment located in the service provider network. )router. Since the service provider n...

Problems solved by technology

[0005] However, the above method of controlling transmission priority needs to configure QoS policies for each user at the entrance of each CE device and the PE router directly connected to each CE device, because there may be A large number of CE devices and a large number of users, therefore, the QoS configuration work at the entrance of CE devices and PE routers is obviously very cumbersome and complicated

Moreover, the existence of a large number of users brings great maintenance pressure. For example, when the needs of users change and the priority changes, it is necessary to adjust the QoS policy at the entrance of a large number of CE devices and PE routers.

That is to say, the method for controlling transmission priority in the prior art has the defects of complex configuration and maintenance work and high configuration and maintenance costs
