Description

Data processing method and system, route device

Technical field

The present invention relates to the communication technology, especially a kind of data processing method and system, route device.

Background technology

In complicated network environment, in order to satisfy service quality (Quality of Service, QOS) etc. professional demand, usually need to carry out a large amount of complex traffic classifications, because can't be according to autonomous system (Autonomous System, AS), clustering information such as group attribute is to message classification, the workload of configuration modification is very big even be difficult to carry out.And use by Border Gateway Protocol (Border GatewayProtocol, BGP) propagate QOS strategy (QOS Policy Propagation Through the BorderGateway Protocol, QPPB) technology can be classified to route by bgp attribute is set in advance by BGP route sender, so just can simplify route recipient's strategy modification, only need the configuration bgp routing policy just can satisfy the demands.

The realization mechanism of QPPB is specially: the BGP route can be carried routing property in announcement process, the BGP Routing Protocol is when neighbours send route, mate routing policy earlier, for the different routing iinformations that send are provided with different BGP routing properties, comprise autonomous system path (AS_PATH), group attribute, extended community attribute etc., these specific attribute are as the sign of BGP route classification.

Bgp neighbor is after receiving route, by inlet routing policy coupling BGP routing property, based on routing property information, comprise the BGP community tabulation, BGP AS path list (paths list), be applied to Access Control List (ACL) (the access control list of router interface, ACL) with prefix list (Prefix list) etc., the coupling routing policy, for the BGP route that receives is provided with the QOS parameter, comprise: IP precedence, QOS local identities (Local ID) and Flow Behavior title (Traffic behavior name) etc., and bgp routing information and the QOS parameter that is associated be issued to router forwarding information base (ForwardInformation Base, FIB) table together; To sorted data flow configuration QOS traffic policy.Like this, in data forwarding process, can use different QOS strategies according to QOS parameters such as the IP precedence that from FIB, obtains, QOS local identities and Flow Behavior titles to the packet that sends to destination network segment, thereby realize by the propagation of BGP to the QOS strategy.

From above process as can be seen, the actual QOS strategy that in bgp routing information, do not send of QPPB technology, just pass through route classification setting routing property at the route transmit leg, configuration QOS strategy on recipient's router interface is provided with the QOS strategy the recipient according to the routing property of destination network segment.Therefore, the QPPB technology can be applied to carry out based on destination address rather than source address the occasion of traffic classification.After recipient's router receives packet, from FIB, search corresponding QOS parameter, after the QOS parameter in matching FIB, carry out corresponding QOS action, thereby realize that QOS guarantees by the source address or the destination address of packet.

When a MPLS provider network can't spread all over all websites at corporate client place, then need to cooperate with other operators, (Virtual Private Network, the interconnected requirement of enterprise security is satisfied in foundation VPN) by cross-domain VPN (virtual private network) between operator's net.At present the feasible cross-domain VPN mode of main flow has two kinds of multiple domain Option A and Option B.As shown in Figure 1, be the structural representation of the cross-domain group network system of prior art, it comprises AS1 and AS2.Option A is cross-domain also to be called cross-domainly back-to-back, adopts that Option A mode is cross-domain can to provide more rich QOS.Business provides node (Service Provider, SP) 1 QOS when adopting Option A mode cross-domain with SP2, border router (Autonomous System BoundaryRouter, ASBR) 1 and ASBR2 between be "VPN routing and forwarding (VRF) instance (VPN Routing/ForwardingInstance, VRF), not that MPLS transmits between them to VRF (VRF to VRF).In order to guarantee that message enters QOS behind another AS from an AS, the value that must will be used to write down MPLS COS (EXP) territory of COS is mapped to the link layer QOS territory between ASBR1 and the ASBR2.In the cross-domain group network system of Option A, ASBR need handle the VPN routing iinformation, and need bear heavier for each VPN configuration VRF instance; In addition, need use a sub-interface at each VPN between the ASBR, increase the complexity of ASBR structure.

Option B is cross-domain also cry single-hop multi-protocols external BGP (Multi-Protocol Exterior BGP, MP-EBGP) cross-domain, be the MP-EBGP adjacent body of setting up single-hop between adjacent domains between the reciprocity ASBR, transmit the VPN-IPv4 route.That is: move MP-EBGP between the reciprocity ASBR, routing iinformations such as the VPN label of propagation VPN-IPv4 route and correspondence, RD/RT.The ASBR of opposite end receives behind the next VPN routing iinformation of MP-EBGP and preserves in this locality, continues backbone network edge (ProviderEdge, PE) router diffusion in own territory again.The advantage of this mode is to have realized the automatic discovery of cross-domain VPN and the automatic announcement of route, does not need all to dispose for each cross-domain vpn service as Option A mode, and autgmentability is better, and the corresponding strategies of cross-domain VPN is also had certain control.In the cross-domain group network system of Option B, transmit VPN information and make up lsp tunnel by normal MPLS/BGP in the AS, transmit VPN information and make up label switched path (Label Switched Path, LSP) tunnel by the MP-EBGP agreement of single-hop between the AS.Between PE1 and ASBR1, and the message between PE2 and the ASBR2, two-layer label is all arranged, the message between ASBR1 and ASBR2 has only one deck label.All implementing QOS according to the outermost layer label value during each node processing message guarantees, therefore, outer layer label sends to opposite end ASBR At time of eject, ASBR shines upon between vpn label and outer layer label, when carrying out the label exchange between the ASBR, (copy) or mapping are duplicated in the EXP territory in the MPLS label.Because the cross-domain mode of VPN Option B is limited to vpn label information is only arranged, no matter be every route or every VPN mode distributing labels, all can't provide VLAN (VirtualLocal Area Network to client's cross-domain flow rate, VLAN)+(Channel Time, QOS CT) guarantees channel time slot.

Realize in the process of the present invention that the inventor finds that there is following problem at least in the cross-domain group network system of existing Option B:

If the inner QOS demand that exists different departments such as management, IT, engineerings of client VPN, the user generally adopts VLAN to divide different business departments, and there is different QOS demands in each department to different business such as voice, video, data.At this moment, because the QOS granularity in the cross-domain group network system of Option B can only arrive the VPN level, can't realize that the QOS of the inner different business of VPN department guarantees.
