Embodiment
In the present invention, comprising in the network system of first network and second network, between first network and second network, comprise primary link and standby link, primary link two ends are main 1 router and main 2 routers, standby link two ends are standby 1 router and standby 2 routers, main 1 router and standby 1 router are positioned at first network, and main 2 routers and standby 2 routers are positioned at second network.Main 1 router is issued the route entry of self by BGP message to main 2 routers.Know the variation of the link bandwidth of main 1 router in order to make winner's 2 routers, on main 1 router, apply the routing policy for main 2 routers: the value that increases the extended community attribute of appointment in all route entries of issuing to main 2 routers, main 2 routers obtain the link bandwidth of main 1 router according to this property value, and then the flow sending to main 1 router according to the variation adjustment of the link bandwidth of main 1 router.Preferably, first network and second network are respectively backbone network and access network.
As shown in Figure 1, be respectively backbone network and access network as example taking first network and second network, introduce the method that service message provided by the invention sends.Wherein, access network is connected by main/slave link with backbone network, and primary link two ends are Router A and Router C, and standby link two ends are Router B and Router D.Between access network and backbone network, notice route by EBGP message.
In the present invention, the routing policy Bandwidth Change of configuration pin to Router A on Router C, this strategy, for all route entries, is the additional extended community attribute of specifying of route entry, the property value mark link bandwidth of extended community attribute.For example, the property value of extended community attribute is med value, med value=N/ actual bandwidth (M), and N is the value of setting according to actual conditions.Suppose N=1000 (or being other values), if actual speed limit bandwidth is 4M, MED=1000/4=250; If there is no speed limit, normal bandwidth is 10M, MED=1000/10=100.Need explanation, determining of med value can also have other modes, for example, when bandwidth speed limiting is cancelled MED=0 can be set.Need explanation, med value can also arrange by other means, and the account form of above-mentioned med value is only the object lesson for illustrating that method provided by the invention provides, and other modes of setting med value can be used equally.
Corresponding with the configuration on Router C, configuration routing policy BandwidthChange on Router A, in the time receiving the route entry that carries extended community attribute, Router A obtains the med value of extended community attribute, and can further calculate link bandwidth according to account form corresponding to this routing policy.
For when the primary link bandwidth speed limiting, reduce primary link burden, Router A on, configure routing policy Path Change, in the time that primary link bandwidth speed limiting satisfies condition, Router A application routing policy PathChange, sends non-core services by standby link.For example, on Router C incoming interface, configure CAR, carry out speed limit for all flows: former bandwidth x (M), speed limit bandwidth z (M), this bandwidth speed limiting satisfies condition, and RouterA sends non-core services by standby link.
Concrete, when bandwidth speed limiting satisfies condition, Router A reduces the priority (Local Preference value) of the route entry of non-core services, makes priority that non-core services forward by primary link lower than the priority forwarding by standby link.For example, the route of two core net that arrive of storage in Router A,, a corresponding primary link,, a corresponding standby link, the route priority of initial primary link is higher than standby link, RouterA makes the priority of the route that standby link is corresponding higher by the route priority of amendment primary link, and non-core services preferentially send to backbone network by standby link.
Need explanation, for example, in the time that primary link bandwidth returns to threshold condition (primary link bandwidth returns to the more than 90% of former bandwidth), RouterA can also recover the priority of the route entry of non-core services, and when primary link bandwidth is met, non-core services preferentially send to backbone network by primary link.
It should be noted that, when primary link bandwidth speed limiting, for fear of flow congestion on Router A, can also on Router A, Congestion Managment be set, for example maximum of Router A limited flow transmission rate is the current maximum bandwidth of primary link.After primary link bandwidth speed limiting is cancelled, Router A cancels the restriction of corresponding flow transmission rate.
In addition, in said method provided by the invention, be not limited in the time of primary link bandwidth speed limiting, non-core services be sent by standby link, other core business also can send by standby link.And non-core services also can specifically be defined as a certain or several business.
Concrete, as shown in Figure 2, the method that service message provided by the invention sends comprises the following steps:
For example, RouterA obtains primary link bandwidth according to med value, and in the time judging that primary link bandwidth speed limiting satisfies condition, Router A sends non-core services according to routing policy Path Change by standby link.Router A configures Congestion Managment, controls the message amount sending to Router C by primary link.Concrete, RouterA issues QoS (the Quality ofService of routing policy Path Change to configuration, service quality) module, QoS module issues a speed limit configuration, for example LR (the total rate limit of physical interface) on specified interface (primary link outgoing interface) according to this routing policy.This specified interface respective links bandwidth of this speed limit configurable limit is the primary link bandwidth that RouterA obtains according to med value.In this way, on specified interface, enable congestion management, avoid primary link generation packet congestion.On specified interface, enable after congestion management, the preferred route of non-core services is replaced by standby link from primary link, shares the bandwidth pressure of primary link by standby link, and improves the efficiency of transmission of message between access network and backbone network.
Concrete, in method provided by the invention, comprise for the configuration of Router C:
On Router C incoming interface, configure CAR, carry out speed limit for all flows: former bandwidth x (M), speed limit bandwidth z (M).On Router C, configure a routing policy Band width Change: this strategy is for all route entries; For example, for the additional extended community attribute of specifying of route entry: 10000: 1; For the additional med value of specifying of route entry, this med value=N/ actual bandwidth (M), wherein the value of N is determined according to actual needs, for example N=1000, and actual speed limit bandwidth is 4M, MED=1000/4=250.Special, mean that bandwidth speed limiting cancels if can set MED=0, it is normal that flow recovers.On Router C, also configure peer attribute: specifying Router A is the peer-to-peer (peer) of Router C; For RouterA specifies routing policy Band width Change; The route entry that router C issues to router C by EBGP carries the routing property of appointment.
In method provided by the invention, comprise for the configuration of RouterA:
On Router A, increase a new routing policy (being actually a new apply action) Band width Change: this strategy for example, for the route entry of the group attribute of specifying: 10000: 1; For these route entries, obtain the med value in routing property according to routing policy Band width Change; According to med value, for example, by the algorithm computation bandwidth=N/MED (M) specifying, N=1000, MED=250, bandwidth=4M.Special, if MED=0 means that bandwidth speed limiting cancels, it is normal that flow recovers.Notice QoS module bandwidth apply QoS bandwidth 4000 (4M) and the interface of specifying.On Router A, configure a routing policy Path Change: this strategy is for the route entry of non-core services; For these route entries, reduce LP (Local Preference, local first level) value (the LP value than Router B is low) according to Path Change.
Through above-mentioned configuration, when Router A receives the BGP route entry that Router C issues, it is the route entry of 10000: 1 that RouterA matches group attribute by routing policy Band width Change, obtain the MED attribute of route entry, calculate primary link bandwidth according to med value, and notify the bandwidth of QoS module primary link reality to change, dynamically issue routing policy Path Change, making the preferred route of non-core services is the link of router B, thereby shares the bandwidth pressure of primary link.Special, if meaning bandwidth speed limiting, cancels MED=0, need to delete the routing policy Path Change dynamically issuing.QoS module receives that the bandwidth on the specified interface of route notice changes, on specified interface, dynamically issue a speed limit configuration LR, bandwidth range after speed limit equals the bandwidth range of route notice, and maximum bandwidth equals primary link actual bandwidth, enables congestion management on specified interface.Special, if bandwidth is 0, the speed limit configuration that QoS module issues before deleting.
