Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of collocation method, equipment and system of differential service pattern of MPLS support.
Background technology
(Differentiated Service DS) has defined a kind of architecture that can implement extendible classification of service on the internet to differential service.A kind of " service " is by in a network, and in same transmission direction, some key character during by one or several path transmits data packets is defined.For instance, these features can comprise throughput, time delay, delay variation etc., can refer to that also it obtains the relative priority of Internet resources.
(Multi-Protocol Label Switching MPLS) is a kind of system that is used for rapid data packet switch and route, and it provides abilities such as target, route, forwarding and exchange for network traffic data in multiprotocol label switching.More specifically be that it has the mechanism of the various multi-form communication stream of management.MPLS is independent of the second and the 3rd layer protocol, and it provides a kind of mode, and the IP map addresses for simply having the label of regular length, is used for different bags and transmits and packet technology.
In order to solve the mapping relations that the MPLS of differential service network boundary IP precedence and MPLS priority are provided, defined three kinds of differential service patterns, these three kinds of differential service patterns are respectively: pipe, short pipe, uniform.In actual applications, different application scenarioss is corresponding to different difference clothes patterns, therefore LER (Label Edge Router, label edge router) is faced with according to different application scenarioss, chooses the problem of the differential service pattern corresponding with this application scenarios from these three kinds of differential service moulds.
Be directed to the problems referred to above, different equipment suppliers' way difference, the equipment supplier who has has desalinated the notion of these three kinds of differential service patterns, supports different differential service patterns by the configuration of physical port mapping mode.
But the deployable of this kind differential service pattern set-up mode is relatively poor, and be difficult to the differential service pattern congruity problem at the two ends of realization mutual communication to a certain extent, because different differential service patterns all is a notion end to end, need Ingress LSR (Ingress LabelSwitching Router, LSR enters the mouth) and Egress LSR (Egress LabelSwitching Router, the outlet LSR) close fit, and being the opposite end that intercoms mutually, this method disposes the differential service pattern of self respectively, when network size is bigger, the differential service pattern congruity problem that solves the two ends of mutual communication by the configuration of physical port is the comparison difficulty, and LSP (Label Switched Path, label switched path) tunnel has the characteristics of dynamic foundation, do not have binding relationship with specific physical port, the differential service pattern congruity problem that solves the two ends of mutual communication by the configuration of physical port is a difficulty.
The equipment supplier's difference according to application scenarios in the partial logic entity that also has disposes corresponding differential service pattern, this partial logic entity such as VPN (Virtual PrivateNetwork, VPN (virtual private network)) and TE (Traffic Engineering, traffic engineering) interface; But because this logic entity is when the differential service pattern at the two ends that configuration intercoms mutually, it is the differential service pattern that disposes two ends respectively, the configuration of the differential service pattern between these two ends does not have association each other, therefore can't solve the differential service pattern congruity problem at the two ends of mutual communication.
