Description
Technical field
The present invention relates to the communication technology, be specifically related to a kind of method and apparatus of realizing the Differentiated Services traffic engineering.
Background technology
Along with IP (Internet Protocol, Internet Protocol) and MPLS (Multi-Protocol LabelSwitching, multiprotocol label switching) application deepens continuously and expands, adopt MPLS TE (Traffic Engineering during most of operators newly-built backbone networks, traffic engineering) and Diff-Serv (Differentiated Services) technology three net (the Internets are provided, telecommunications network, Broadcasting Cable Network) unification is professional, when providing bandwidth to guarantee, need to realize in one network the target of the business that the multiple different QoS of carrying (Quality of Service, service quality) requires.At NGN (Next Generation Network, next generation network), LDP over TE (Label Distribution Protocol over TE, traffic engineering carrying tag distribution protocol), PWE3 (Pseduo Wire Emulation Edge-to-Edge, the pseudo wire emulation of edge-to-edge) in the solution of multiple business such as, DS-TE (Diffserv-TE, Differentiated Services traffic engineering) is one of necessary characteristic.
Diff-Serv is as a kind of QoS solution, and its main realization mechanism is that flow is divided according to COS, provides different QoS to guarantee based on COS.And MPLS TE is as traffic engineering solution, and the use that is mainly used in Internet resources is optimized.MPLS TE allows to set up LSP (Label switch path, label switched path) tunnel based on the constraint route, can be on the path of appointment bandwidth resource.
DS-TE can carry out network resource optimization based on the flow of dividing by COS in conjunction with the two advantage, promptly different COS is carried out different bandwidth constraints.The unified bandwidth service of the not Differentiated Services type that provides with respect to MPLS TE, DS-TE is divided into different CT (Class Type according to the bandwidth constraint model with flow, type of service), take total bandwidth respectively according to a certain percentage, every kind of CT uses different qos policys respectively, such as transmitting service fast and guaranteeing the service of transmitting, like this, both can provide strict bandwidth to guarantee service, and also can guarantee the utilance of link bandwidth.
MPLS DS-TE is aimed at each service class in essence and carries out traffic engineering, is the traffic engineering technology on a kind of more fine granularity.MPLS DS-TE has increased the function based on class discrimination on original MPLS TE technical foundation, mainly be to use E-LSP (Exp-inferred-PSC LSP at present, derive the LSP of packet switching by EXP) realize, this mechanism is at the LSP inlet EXP position to be set suitably, determine the scheduling behavior of PHB (Per Hop Behavior, per hop behavior) by EXP.
E-LSP sets up the process complexity at present, and relevant configuration is also very complicated, needs expanded signalling and Routing Protocol; And the business of Differentiated Services is transmitted by same paths in the E-LSP technology, thereby the ability of avoiding risk is not good.
Summary of the invention

Embodiment
With reference to Fig. 1, Fig. 1 shows the flow process that the embodiment of the invention realizes the method for Differentiated Services traffic engineering, mainly may further comprise the steps:
Which kind of tunnel protocol is all by carrier, the different encapsulation format of transmission and be transmitted that packet forms.Can adopt with at present identical mode and set up described tunnel.Such as, for the MPLS tunnel, a MPLS tunnel promptly is a strip label switching path (LSP:Label Switch Path), is that the work by label distribution protocol realizes.Label distribution protocol is that mark/forwarding equivalence class (FEC:Forwording EquivalenceClass) that LSR (LSR:LabelSwitch Router) is done it is bound the protocol suite of notifying another LSR, and two LSR of usage flag distribution protocol exchange labeling/FEC binding information are called as the mark distribution peer-entities corresponding to corresponding binding information.Label distribution protocol also comprises any negotiation that mark distribution peer-entities carries out in order to know MPLS ability each other.
Can select two or more is traffic engineering tunnel group with the tunnel binding of answering the different business COS respectively, form a traffic engineering tunnel group such as selecting 8 tunnels, the COS in these 8 tunnels has nothing in common with each other, that is to say that this traffic engineering tunnel group can provide the traffic transport of 8 kinds of different service types for the user.
When the user needs professional transmission, can select to meet the traffic engineering tunnel group of business demand for this user by ingress router.During concrete the selection, multiple mode can be arranged.Such as, can select according to the traffic engineering tunnel group title of user's appointment; Can also select according to predefined tunnel group policy.
When employing is selected the mode of traffic engineering tunnel group according to the traffic engineering tunnel group title of user's appointment, can provide corresponding selection interface for the user, select the interface to obtain the traffic engineering tunnel group title of user's appointment by this, select corresponding traffic engineering tunnel group according to this title.Need to prove that described user is meant service provider, this service provider is known the attribute of each traffic engineering tunnel group and the type of service that can support thereof, thereby can select the traffic engineering tunnel group that meets business demand.
When selecting the mode of traffic engineering tunnel group according to predefined tunnel group policy, can pre-configured tunnel group policy, such as: random selection strategy, according to service attribute and tunnel attribute selection strategy, service attribute and tunnel group name claim such as setting up, the corresponding relation of each tunnel attribute in the tunnel group, and this corresponding relation is kept in the ingress router, when ingress router is received need transmit professional, obtain this professional type, mate described corresponding relation according to this type of service then, thereby select the traffic engineering tunnel group that meets business demand.These tunnel group policies may be used alone, can also be used in combination.
Each the traffic engineering tunnel group corresponding service that can set up is in advance transmitted.Owing to comprised the tunnel of a plurality of corresponding different service types in the described traffic engineering tunnel group, such as, the tunnel of corresponding speech business, the tunnel of corresponding data business, and each bar tunnel has different property parameters (such as bandwidth etc.), to satisfy the demand of different business.Therefore, described business is transmitted the forwarding-table item that has comprised all tunnels in this traffic engineering tunnel group, and this forwarding-table item comprises: COS, the information such as Tunnel Identifier corresponding with described COS.When needs transmit described business, transmit according to this business of setting up in advance and to be the described service selection described business of one or more tunnel transmission wherein, such as, for the MPLS message, can select the tunnel corresponding according to the experiment territory (Exp) in the MPLS message with this Exp; For the IP message, can select the tunnel corresponding according to the COS territory in the IP message (Cos:Class of Service), thereby realize the traffic engineering of Differentiated Services with this Cos.
