Embodiment Construction

[0044] In the embodiment of the present invention, different BGP community attributes are set for different departments of the user VPN on the PE, and different inner labels are allocated to different VPN departments based on the BGP community attributes. In the cross-domain VPN of Option B, the QOS policy based on the community attribute is deployed through QPPB, and the traffic VLAN QOS is implemented for the user's cross-domain traffic through the inner layer label, so as to provide the QOS guarantee for the VLAN access of different departments. In addition, different outer labels can be assigned based on service types, so that the inner labels of MPLS packets transmitted between ASBRs carry both the BGP community attribute and the value of the EXP field in the outer labels encapsulated when MPLS packets are generated. QOS guarantee for different types of business. The business department in this embodiment of the present invention may specifically be a business department ...

Abstract

The invention relates to a method for processing data, and a system and a routing device thereof. The method comprises the following steps: receiving a first multi-protocol label switching (MPLS) message including a first inner layer label, of which the value is used for identifying and sending / receiving a service agent to which the user of the first MPLS message belongs; and switching the first inner layer label in the first MPLS message to a corresponding second inner layer label; acquiring a first quality of service (QoS) strategy corresponding to the second inner layer label, switching the label to generate a second MPLS message for implementing the first QoS strategy, and sending the second MPLS message to a second autonomous system boundary router (ASBR) of a second autonomous system (AS). The embodiment of the invention can meet the requirements for different service agents in a virtual private network (VPN) on QoS.

Description

technical field [0001] The invention relates to communication technology, in particular to a data processing method and system, and a routing device. Background technique [0002] In a complex networking environment, in order to meet the requirements of services such as Quality of Service (QOS), it is usually necessary to perform a large number of complex traffic classifications, because it is impossible to cluster information according to autonomous systems (Autonomous System, AS), community attributes, etc. For packet classification, the workload of configuration modification is very heavy and even difficult to implement. However, the QOS Policy Propagation Through the Border Gateway Protocol (QPPB) technology can be used by the BGP route sender to classify the routes in advance by setting the BGP attribute, which can simplify the route receiver. To modify the policy, you only need to configure the BGP routing policy to meet the requirements. [0003] The implementation ...
