Detailed description of the invention
Because existing map bindings mode is only based on General Physics port with based on two kinds of VLAN, when uncommonHope and bind or bind based on certain vfi based on certain trunk port, may need one by oneVlan or port basis ground are bound, and more loaded down with trivial details, flexibility is poor, convenient not. When binding certainWhen the vlan of vfi or physical port binding relationship many or physical port and place vlan is inconsistent,Use the more loaded down with trivial details conflict that even occurs binding relationship that will seem of existing binding strategy. Therefore thisBright two kinds of new map bindings modes are proposed: the map bindings mode based on trunk and based on vfi'sMap bindings mode:
The mapping policy of configuration based on Trunk group; Organize when having from Trunk the report that any member port entersWhen literary composition forwards by VPLS tunnel, this message is carried out to the mapping policy of configuration in trunk group, described inMapping policy based on Trunk group includes tunnel mapping strategy and goes out tunnel mapping strategy. Should be based onThe mapping policy of Trunk group is configured on tunnel portal equipment and tunnel exit equipment, wherein enters in tunnelThe mapping policy configuring on jaws equipment is for entering tunnel mapping strategy, the mapping configuring on tunnel exit equipmentStrategy is for going out tunnel mapping strategy.
The mapping policy of configuration based on vfi; On described tunnel portal equipment, when have from following anyWhen the message that port enters forwards by VPLS tunnel, this message is carried out to the mapping plan of the upper configuration of vfiSlightly: bound vfi physical port, bound the vlan of vfi member port, bound the trunk of vfiThe member port of group; The described mapping policy based on vfi includes tunnel mapping strategy. Should be based on vfi'sMapping policy is only configured on tunnel portal equipment.
Above-mentioned two kinds of map bindings modes can exist simultaneously, also can select a use.
Entering tunnel mapping strategy comprises: at tunnel portal place, by TOS or the message of message IP headThe PRI value of VLANtag (label) head is mapped to the EXP position of MPLS label;
Going out tunnel mapping strategy comprises: at tunnel exit place, the EXP value of MPLS label is mapped to reportOn the TOS of literary composition IP head or the PRI of message VLANtag head.
For convenience of description, hereinafter the PRI of the TOS of message IP head and VLANtag head is referred to asFor COS.
Preferably, carry out above-mentioned configuration and mapping policy executable operations by switch.
As shown in Figure 1, port p1, p2 and p3 form Trunk group to map bindings based on Trunk group1, this Trunk group 1 is carried out to the configuration of mapping policy, when switch is as tunnel portal equipment, and fromWhen the common message that in p1, p2, p3, any one or several port enter is walked VPLS tunnel and forwarded, hand overWhat the execution of changing planes configured trunk group 1 in advance enters tunnel mapping strategy, by the cosX mapping in messageFor the expY in MPLS label; When switch is as tunnel exit equipment, and from p1, p2, p3When the MPLS message that any one or several port enter is walked the forwarding of VPLS tunnel, switch is carried out pre-First to 1 configuration of trunk group go out tunnel mapping strategy, by the expY mapping in MPLS message labelFor the cosX in common message after label peeling.
As shown in Figure 2, port p1 is physical port independently to map bindings based on vfi, port p2With p3 composition Trunk group 1, port p4 belongs to vlan1, port p4, Trunk group 1, vlan1 all withVfiA binding, carries out the configuration of mapping policy to this vfiA, when the message that has a VPLS tunnel from p1,When in p2, p3, p4, any one or several port enter switch, switch is carried out in advance to vfiAThe mapping policy of configuration, is mapped as the expY in MPLS label by the cosX in message.
For tunnel portal equipment, the trunk group under physical port or port or port place vlanOn bound VFI, the message entering from this port need to forward by VPLS tunnel; For tunnelOutlet device, if the affiliated vlan of message inbound port has opened MPLS function and message is MPLS message,This message need to forward by VPLS tunnel.
For the physical port that belongs to tunnel portal equipment, on it, may only dispose the mapping based on portBinding, or only dispose the map bindings based on trunk group, or the mapping of only disposing based on vlan is tied upFixed, or only dispose the map bindings based on vfi, also possible configuration has two or more mappingBinding, for example:
Comprise following arbitrary map bindings: based on the map bindings of port and trunk group; Based on port andThe map bindings of vlan; Based on the map bindings of port and vfi; Based on the mapping of trunk group and vlanBinding; Based on the map bindings of trunk group and vfi; Based on the map bindings of vlan and vfi; Based on port,The map bindings of trunk group and vlan; Based on the map bindings of port, trunk group and vfi; Based on port,The map bindings of vlan and vfi; Based on the map bindings of trunk group, vlan and vfi; Based on port, trunkThe map bindings of group, vlan and vfi.
For the physical port that belongs to tunnel exit equipment, its associated map bindings mode comprises followingOne of arbitrary: the map bindings mode based on port; Based on the map bindings mode of trunk group; Based onThe map bindings mode of vlan; Based on the map bindings mode of port and trunk group; Based on port and vlanMap bindings mode; Based on the map bindings mode of trunk group and vlan; Based on port, trunk groupMap bindings mode with vlan.
Tunnel portal equipment and tunnel exit equipment can be same equipment.
For fear of the conflict of the mapping policy that may exist, distribute one for every kind of map bindings mode in advanceIndividual priority, is respectively the map bindings mode based on port, the map bindings side based on trunk groupFormula, the map bindings mode based on vlan and the map bindings mode based on vfi are distributed priority (ratioAs represented by numeral 1,2,3,4).
The qos mapping method avoiding conflict that the present invention proposes comprises: receiving after message judgementReceive the priority of all map bindings modes associated on the physical port of message, according to pre-set patternSelect a kind of map bindings mode, using mapping policy corresponding this map bindings mode as to described reportThe mapping policy of literary composition, when described message is forwarded by VPLS tunnel, carries out this mapping to described messageStrategy.
Preferably, above-mentionedly select a kind of step of map bindings mode to comprise according to pre-defined rule: selecting shouldThe associated the highest map bindings mode of map bindings mode medium priority on physical port. When on portWhen associated map bindings mode only has one, this map bindings mode is the highest that of priority.
For example, for tunnel portal equipment, when a port belongs to a trunk group, this trunk organizes againBelong to certain vlan, and on this vlan, bound vfi, if trunk group, port under port, portOn the vfi that place vlan, vlan bind, all configure mapping policy, and each map bindings mode correspondenceMapping policy not identical, now there will be conflict. The mapping priority of supposing port (is shone upon and is tied upDetermine priority corresponding to mode) be 2, the mapping priority of trunk group is 1, the mapping priority of vlanBe 4, the mapping priority of vfi is 3, wherein, 4 priority is the highest, 1 priority is minimum. Now,Can be this port and select the highest map bindings mode of mapping priority---the corresponding mapping policy of vlanThe mapping policy going out as decision-making. Like this, when the message entering from this port passes through vpls tunnel transmission,Carry out mapping according to the mapping policy that under this port, vlan configures. Idiographic flow is referring to Fig. 3. ForTunnel exit equipment, selects the idiographic flow of map bindings mode referring to Fig. 4.
Realize the system of above-mentioned qos mapping configuration, comprise that map bindings mode confirms subsystem, mapping planSlightly determine subsystem and mapping policy executive subsystem, wherein:
Described map bindings mode is confirmed subsystem, and for receiving after message, judgement receives messagePhysical port on the priority of associated map bindings mode;
Described mapping policy is determined subsystem, for select a kind of map bindings mode according to pre-defined rule,Using mapping policy corresponding this map bindings mode as the mapping policy to described message;
Described mapping policy executive subsystem, while forwarding for described message is passed through to VPLS tunnel, rightDescribed message is carried out this mapping policy.
Particularly, map bindings mode selection scheme when conflict appears in the mapping policy of tunnel portal equipmentAs shown in Figure 3, comprise the following steps:
Step 301, current port receives common message, reads the mapping priority conduct of current portCurrent priority;
Step 302, judges whether current port binds vfi, if so, and execution step 314, otherwise holdRow step 303;
Step 303, judges whether current port belongs to trunk group, if so, execution step 304, noPerform step 310;
Step 304, judges whether trunk group has bound vfi, if so, and execution step 308, otherwise holdRow step 305;
Step 305, judges that whether port or the affiliated vlan of trunk group have bound vfi, if so, carry outStep 306, otherwise, execution step 311;
Under port and trunk group, vlan must be same vlan.
Step 306, judges that whether the priority of vlan is higher than current priority, if so, and execution step307, otherwise execution step 308;
Step 307, using the mapping priority of this vlan as current priority, execution step 308;
Step 308, judges that whether the priority of trunk group is higher than current priority, if so, and execution stepRapid 309, otherwise, execution step 314;
Step 309, using the mapping priority of this trunk group as current priority, execution step 314;
Step 310, judges whether the affiliated vlan of current port has bound vfi, if so, and execution step312, otherwise, execution step 311;
Step 311, forwards according to prior art this message by non-VPLS tunnel, finish;
Step 312, judges that whether the priority of vlan is higher than current priority, if so, and execution step313, otherwise, execution step 314;
Step 313, using the mapping priority of this vlan as current priority, execution step 314;
Step 314, judges that whether the priority of vfi is higher than current priority, if so, and execution step315, otherwise, finish;
Step 315, using the mapping priority of this vfi as current priority, finishes.
The map bindings mode that current priority is corresponding is selected map bindings mode, with this mappingBinding mode enter tunnel mapping strategy, the message receiving is carried out into tunnel mapping.
Above flow process is only example, in actual application, can have multiple variation, for example, can not establish and work asFront priority. Or first determine all map bindings modes when front port shangguan connection, therefrom select preferentialThe highest map bindings mode of level, then using mapping policy corresponding this map bindings mode as to messageMapping policy.
The setting of the priority of different mappings binding mode can be more flexible, and recommended priority is port <Trunk group < vlan < vfi.
Map bindings mode selection scheme when conflict appears in the mapping policy of tunnel exit equipment is as Fig. 4 instituteShow, comprise the following steps:
Step 401, tunnel exit equipment is received MPLS message, reads the mapping priority of current portAs current priority;
Step 402, judges whether current port belongs to trunk group, if so, execution step 403, no, execution step 405;
Step 403, judges whether the priority of trunk group is greater than current priority, if so, carries out stepRapid 404, otherwise, execution step 405;
Step 404, using the mapping priority of this trunk group as current priority, execution step 405;
Step 405, judges whether the priority of port or the affiliated vlan of trunk group is greater than current priority,If so, execution step 406, otherwise, finish;
All port or trunk group all must belong to certain vlan, even if switch without any configuration,Port or trunk group also have an acquiescence vlan (being generally vlan1).
Step 406, using the mapping priority of this vlan as current priority, finishes.
The map bindings mode that current priority is corresponding is selected map bindings mode, with this mappingBinding mode go out tunnel mapping strategy, the message receiving is carried out out to tunnel mapping.
Such scheme is the processing scheme that when conflict appears in the mapping policy of different mappings binding mode, and phaseThere will not be conflict with the mapping policy between map bindings mode, be analyzed as follows:
Because a port can not belong to multiple trunk groups, therefore configure different reflecting between different trunk groupPenetrate strategy and can not cause conflict;
Belong to the situation of multiple vlan for same port or same trunk group, due to the vlan that enters of messageOnly there is one, also can not cause conflict therefore configure different mapping policys under different vlan in this case;
Because same port or same trunk group or same vlan can not bind multiple vfi, therefore differentBetween vfi, configure different mapping policys and also can not cause conflict.
