Embodiment
The embodiment of the invention is passed through configure user special line group on PE equipment, and tackles the message forwarding process mutually and improve, and has realized the user's special line technology in the VPLS territory, has expanded the access way of user side AC (Attachment Circuit, place in circuit).
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
Present embodiment has been described the execution mode of realizing user's special line communication between the AC that is linked into same PE equipment under arbitrary VSI.
In the present embodiment; At first on PE equipment, dispose local special line group, two local CEs (Custom Edge, user border networks equipment) the pairing AC of its member for needing to adopt user's private-line mode to communicate; E-Packet each other between these two AC, form user's special line.
Concrete, can in the VPLS instance of control aspect, create two AC, and the member AC (being called special line AC) that these two AC are set is same local special line group.Above-mentioned configuration can be accomplished through the static configuration mode.
For example, for the VPLS network architecture as shown in Figure 1,, PE1 need adopt user's private-line mode to communicate if going up the CE10 and the CE12 that connect; Wherein, CE10 is connected in PE1 through AC1, and CE12 is connected in PE1 through AC2, then when configuration AC inserts in VSI on the PE1; Directly specify the switch-in attribute of corresponding AC (being AC1 and AC2) to be access via telephone line and to provide the special line group number, create user's special line between corresponding CE thereby be implemented in.Concrete, can on PE1, dispose as follows:
Vsi vsi1 static//VPLS instance of establishment, instance is called vsi1
The signaling protocol of pwsignal ldp//appointment VPLS is LDP (Label Distribution Protocol, a tag distribution protocol)
The ID of vsi-id 500//appointment VPLS instance is 500
Service-instance 1//AC of establishment, the AC sequence number is 1
The packaged type of encapsulation private-line id 1 Qos 1//appointment AC is a private-line mode, and special line ID is 1, and the QOS attribute is 1
Xconnect vsi vsi1//this AC is tied to vsi1
Service-instance 2//AC of establishment, the AC sequence number is 2
The packaged type of encapsulation private-line id 1 Qos 2//appointment AC is a private-line mode, and special line ID is 1, and QoS (Quality of Service, service quality) attribute is 2
Xconnect vsi vsi1//this AC is tied to vsi1
Wherein, the QoS attribute of AC1 is set to 2, and expression is after receiving message from AC1, and the QoS priority of this message is set to 2, and in like manner, the QoS attribute of AC2 is set to 1, and expression is after receiving message from AC2, and the QoS priority of this message is set to 1.In practical application, can the QoS property value be set according to service needed, for example, it is 1 or 2 that the QoS property value is set, and wherein the QoS property value is high more, and the QoS priority of the flow that gets into from this AC is just high more.But the QoS attribute is an arrangement.
Through above-mentioned configuration, in the VPLS of control aspect instance, created two special line AC:AC1 and AC2, AC1 and AC2 belong to same local special line group, and this user's special line group identifies with special line ID, thereby between CE10 and CE12, forms user's special line.
The foundation that E-Packets between the member AC in the local special line group is the local special line group of above-mentioned configuration; And do not rely on mac address table; Therefore PE2 goes up and removes the broadcasting table that has disposed this VSI 1; The MAC table of VSI 1 has also disposed the special line group of the special line group 1 of VSI 1 and has transmitted, and this special line group is transmitted the interface of the AC1 that comprises special line group 1 and the interface of AC2.When PE2 receives the Ethernet message through AC1 or AC2; The interface of another AC during this special line group transmitted is transmitted the Ethernet message of receiving as outgoing interface, realizes transmitting in the special line group; Need not carry out source MAC study and target MAC (Media Access Control) address inquiry, also can not cause producing in the VSI 1 broadcasting.
Based on above configuration, the flow process of between the local AC on the PE equipment, carrying out the communication of user's private-line mode can be as shown in Figure 2, comprising:
With PE2 equipment among Fig. 1 is example, after PE2 equipment receives the Ethernet message, according to receiving the port of Ethernet message and the VLAN ID (VLAN ID) of Ethernet message, parses and receives that the Ethernet message is AC1 usually.PE2 parses this AC1 and is associated with VSI 1 and special line group 1 according to the above-mentioned configuration of AC1
Concrete, the PE2 among Fig. 1 can find special line group 1 with special line group 1 according to parsing VSI 1 and transmit.
Concrete; PE2 among Fig. 1 transmits the special line group of the special line group 1 of VSI 1 and comprises corresponding interface of AC1 and the corresponding interface of AC2; Therefore the interface that AC2 was corresponding during PE2 transmitted this special line group is transmitted the Ethernet message of receiving as outgoing interface (receiving the corresponding interface corresponding interface of other AC in addition of AC of Ethernet message) through this outgoing interface.
The Ethernet message that PE2 equipment receives through AC1 among Fig. 1 so can not be forwarded to other AC or the PW (Pseudo Wire, virtual link) of VSI 1.
Further, if be the identical or different QoS attribute of AC1 and AC2 configuration of the special line group 1 of VSI 1, then PE2 equipment also the QoS priority of this Ethernet message of receiving be set to the indicated priority of this QoS attribute.
In step 202; If PE2 equipment belongs to VSI 1 according to the place in circuit of resolving but does not belong to special line group 1; Then PE2 transmit this Ethernet message according to existing mode, carry out source MAC inspection and study earlier, mate the corresponding interface (AC interface or PW interface) of purpose MAC again; The interface that purpose MAC is corresponding is confirmed as outgoing interface, transmits the Ethernet message of receiving; Be the interface of purpose MAC corresponding A C, then transmit the Ethernet message,, VPLS is transmitted from outgoing interface if the corresponding PW interface of purpose MAC then according to this PW interface encapsulation corresponding outer layer label and vpn label, generates the VPLS message through the interface of this AC.If PE2 do not learn purpose MAC in VSI 1, then according to the broadcasting table of VSI 1,, then other AC interface outside the interface of the AC that receives the Ethernet message is broadcasted this message with the PW interface.PE2 writes down the interface separately of AC1 and AC2 in the special line group 1 that generates VSI 1 is transmitted, then can not receive the broadcasting in the VSI 1 again with the broadcasting table of AC1 and AC2 interface adding VSI 1 separately.
Though present embodiment is an example with the setting and the forwarding of the special line group that is made up of two AC that are linked into same PE only; But those skilled in the art are according to the present embodiment content; In VSI, create a plurality of special line groups in an identical manner; Each special line group all comprises at least two AC and on PE2 equipment, is provided with unique special line ID, can not E-Packet each other between the AC of different special line groups.Communication process between the pairing CE of member AC in the set-up mode of each local special line group and each the local special line group all can adopt aforesaid way to realize.
Further; Also can comprise three above member AC in the local special line group that disposes on the PE equipment; In such cases, PE equipment adopts the multicast mode after receiving message from local special line group membership AC incoming interface; The pairing outgoing interface of other member AC except this message incoming interface AC is transmitted this message from the special line group membership AC of this this locality respectively, thereby in this this locality special line group, realizes the private-line mode communication of point-to-multipoint.After receiving the Ethernet message that the AC of special line group transmits for ease of PE equipment; The Ethernet message that forwarding is received on other AC more than two in the special line group; Can further when configuration special line group, the pass-through mode of corresponding broadcast/multi broadcast be set for each AC of special line group.
Can find out through the embodiment of the invention; The Ethernet message of the AC reception of special line group is not done source MAC study to PE equipment and target MAC (Media Access Control) address is searched; Only be forwarded to other AC of special line group, thereby both realized local user's special line communication, saved the memory space of mac address table again.PE equipment is for the broadcasting packet of the special line group AC reception in addition of VSI or the AC that the unknown unicast message can not be broadcast to the special line group, and broadcasting packet or unknown unicast message for VSI public network side (PW) gets into can not be broadcast to special line AC side yet.So got rid of fully that the service traffics of other AC outside the special line group and public network side PW are forwarded to the AC of special line group among the VSI, thereby guaranteed between the special line group AC of VSI, to carry out the flow intercommunication.
Embodiment two
Present embodiment has been described under arbitrary VSI, is linked into the execution mode of realizing user's special line communication between the AC of different PE equipment.
In the present embodiment, dispose the special line group respectively on the PE that at first each AC inserts in the special line group.
For example; For the VPLS network architecture as shown in Figure 3, if the CE40 that is connected on the CE10 that PE1 go up to connect and the PE4 need adopt user's private-line mode to communicate, wherein; CE10 is connected in PE1 through the local AC1 of PE1; CE40 is connected in PE2 through the local AC2 of PE2, then when configuration AC inserts in VSI on the PE1, disposes as follows:
Vsi vsi1 static//VPLS instance of establishment, instance is called vsi1
The signaling protocol of pwsignal ldp//appointment VPLS is LDP
The ID of vsi-id 500//appointment VPLS instance is 500
Peer 4.4.4.4//appointment VPLS opposite end PE4
Peer 3.3.3.3//appointment VPLS opposite end PE3
Peer 6.6.6.6//appointment VPLS opposite end PE6
Service-instance 1//AC of establishment, the AC sequence number is 1
The packaged type of encapsulation private-line global-id 1 qos 1 peer 4.4.4.4//this AC of appointment is overall private-line mode, and special line group ID is 1, and the QoS attribute is 1, and this special line is that clean culture and appointment opposite end are PE4.
Xconnect vsi vsi1//this AC is tied to vsi1
Based on above-mentioned configuration, PE1 has disposed these VSI 500 broadcasting tables and special line group 1 is transmitted, the corresponding PW interface of PW that this special line group 1 is transmitted the AC interface that comprises AC1 and connected PE4.VSI 1 broadcasting table does not then write down the interface of special line group 1 in transmitting.
When configuration AC inserts in VSI on the PE4, dispose as follows:
Vsi vsi1 static//VPLS instance of establishment, instance is called vsi1
The signaling protocol of pwsignal ldp//appointment VPLS is LDP
The ID of vsi-id 500//appointment VPLS instance is 500
Peer 1.1.1.1//appointment VPLS opposite end PE1
Peer 3.3.3.3//appointment VPLS opposite end PE3
Peer 6.6.6.6//appointment VPLS opposite end PE6
Service-instance 2//AC of establishment, the AC sequence number is 2
The packaged type of encapsulation private-line global-id 1 qos 2 peer 1.1.1.1//this AC of appointment is overall private-line mode, and special line group ID is 1, and the QoS attribute is 2, and this special line is that clean culture and appointment opposite end are PE1
Xconnect vsi vsi1//this AC is tied to vsi1
The QoS attribute that PE4 inserts the AC2 of this equipment is set to 2, and expression is set to 2 from the QoS priority of the flow that this AC inserts.In practical application, can the QoS property value be set according to service needed, for example, it is 1 or 2 that the QoS property value is set, and wherein the QoS property value is high more, and the QoS priority of the flow that gets into from this AC is just high more.But the QoS attribute is an arrangement.
The last broadcasting table and the special line group 1 that have disposed this VSI 500 removed of PE4 transmitted, and this special line group 1 is transmitted the interface PW interface corresponding with the PW that is connected PE1 that comprises AC2.
Therefore the embodiment of the invention is improved the forwarding of the message on source end and destination PE equipment handling process; The Ethernet message that promptly the AC side gets into from the special line group can be transmitted at other AC and all PW of special line group; Can transmit at all AC of special line group from the VPLS message that the PW side of special line group gets into, forbid source MAC study and target MAC (Media Access Control) address inquiry (as can be) through closing MAC address learning function and the realization of Bridge function on the special line AC interface.When wherein on PW, carrying out the forwarding of VPLS message; According to the corresponding PW interface of the PW of peer end of the connection PE for the corresponding tunnel label of Ethernet message encapsulation with beyond the VC label; Also will with under the identification information of long-range special line group be encapsulated in the VPLS message so that destination PE equipment is according to this long-range special line group id.The message that carries out in the special line group is transmitted.
Based on above configuration, the flow process of carrying out the communication of user's private-line mode at the PE equipment room can be as shown in Figure 4.This flow process mainly comprises:
Wherein, carrying the message encapsulation format of long-range special line group identity information can be as shown in Figure 5.As shown in the figure, present embodiment is expanded the control word in the VPLS message.Concrete; Use original Sequence number (sequence number) field to carry special line group id information; To its last reservation bit of Rsvd reserved field expansion; This bit is set to Z mark (representing to carry in this VPLS message long-range special line group ID), is about to original reserved field and reduces by a bit, and the Flags field is increased a bit.
Need to prove that VPLS message format shown in Figure 5 is merely a kind of example, as long as make it carry long-range special line group id through expansion VPLS message, all should be within protection scope of the present invention.
Further, if for the corresponding AC of the incoming interface of this message is provided with the QoS attribute, then PE equipment also the QoS priority of this message be set to the indicated priority of this QoS attribute.As can with the QoS best property of attribute mapping in the EXP field of message, so just can the QoS attribute of the last AC side of source PE be carried on the far-end PE.
Step 406 is resolved the special line group of VPLS message and is transmitted sign and related Virtual Switch Instance and special line group;
According to the form of VPLS message shown in Figure 5, whether this opposite end PE equipment can carry long-range special line group id according to this message of Z marker for judgment of Rsvd reserved field.
Concrete; This opposite end PE4 equipment carries long-range special line group id if judge in this message; Then not carrying out source MAC study and target MAC (Media Access Control) address searches; But according to the form of VPLS message shown in Figure 5, this opposite end PE4 device parses goes out the special line group ID that Sequence number field is carried, and confirms to belong to the local AC of this special line group ID then according to the long-range special line group that disposes on this PE equipment; Inquire about the corresponding outgoing interface of this AC, and bullet is fallen the VC label be transmitted to local CE from this outgoing interface with the message of removing long-range special line group id.If this opposite end PE4 does not find the local special line AC of this special line group, then handle, as abandon this message according to default policy.
In step 402, PE1 equipment is not transmitted sign if parse the special line group, then adopts existing mode to transmit in public network side and/or local side.
In step 405, this opposite end PE4 equipment is not transmitted sign if parse the special line group, then adopts existing mode, transmits this message in this locality.Carrying out corresponding source MAC study and target MAC (Media Access Control) address searches.After the target MAC (Media Access Control) address according to this message inquires corresponding outgoing interface, transmit this message from this outgoing interface.If do not inquire corresponding outgoing interface,, only transmit in this locality then according to horizontal partition principle.。
In the VSI instance special line group can be set; Unique special line ID is all arranged on the PE equipment in each special line group; At least comprise the AC that is linked into different PE equipment more than two in each special line group, but can not E-Packet each other between the AC of the different special line groups of identical VSI.Communication process between the pairing CE of member AC in the set-up mode of each special line group and each the special line group all can adopt aforesaid way to realize.
The broadcasting packet or the unknown unicast message that get into for other AC sides that guarantee in the VSI can not be broadcast to special line AC side; And the public network side gets in the VSI broadcasting packet or unknown unicast message can not be broadcast to special line AC side, do not comprise special line AC node in the broadcasting table of the embodiment of the invention in VSI.Concrete; In the embodiment of the invention; The VPLS key-course increases this AC node in the broadcasting table of this VSI instance when creating the common AC (being non-special line AC) of VPLS instance, and when creating the special line AC of VPLS instance; Do not revise the broadcasting table of this VSI instance, promptly can in the broadcasting table of VSI instance, not add this special line AC node.
Further, also can comprise local member AC more than two in the special line group that disposes on PE equipment.In such cases:
After PE equipment receives message from the incoming interface AC of special line group; Comprise local AC more than two if inquire in the special line group under this incoming interface AC, then also other local member AC except that the incoming interface AC of this message the corresponding outgoing interface of message from this special line group transmitted;
When PE equipment when the PW side joint is received the message that carries the special line group id; If inquire in the corresponding special line group and comprise local member AC more than two; Then adopt the multicast mode; With the message behind removal VC label and the special line group id, the outgoing interface that the local member AC from this special line group is corresponding is respectively transmitted.
Through above flow process, realized between the member AC that belongs to same special line group on two PE equipment, carrying out user's private-line mode communication of point-to-multipoint.
With the VPLS network architecture shown in Figure 3 is example, is configured to the special line AC of same special line group such as the AC2 on AC1 on the PE1 equipment and the PE2 equipment.User's message from the AC1 entering; PE1 obtains incoming interface attribute (being the aforementioned configuration time institute's information configured of on PE1, carrying out inserting in the VSI) according to the incoming interface of this message; Because it is message (like encapsulation private-line global-id 1 qos 1peer 4.4.4.4) in the special line group that this incoming interface attribute-bit goes out this message; Then PE1 obtains special line group ID (global-id 1), VC label and public network outgoing interface information; Packaging V C label, special line group id and public network tunnel header information in message; Then this message is forwarded to public network side PW, carries out the label exchange according to the tunnel label of public network head when message is transmitted on public network, arrive opposite end PE equipment PE2 at last.What PE2 received is the VPLS message that carries VC label and special line group ID; PE2 sends the PE end according to VPLS instance under this message of VC tag recognition and message source; According to the special line group under the internal layer special line group ID identification message; The source MAC of forbidding carrying out after message belongs to the special line group in the VSI is learnt and target MAC (Media Access Control) address is searched identifying; But the special line group of directly safeguarding according to this PE2 finds the special line AC in the group, and the message that will peel public network head, VC label and special line group ID off is forwarded to the corresponding outgoing interface of this special line AC.
In the above-mentioned flow process, the heading information when message is transmitted on each equipment can be as shown in Figure 6.Wherein, What PE1 received from user side is two layers of Ethernet message of user; Packed VC label and the Tunnel label (the public network tunnel label is like the Tunnel among the figure) gone up of message when transmitting back entering public network through VPLS is if user side is the special line AC of special line group; Then behind the VC label, also can carry control word (CtrlWord), the Sequence Number of this control word is used to identify special line group ID.After PE4 receives this message, remove VC label and Tunnel label, also be packaged with at this message under the situation of the control word of carrying special line group ID, also will remove this control word, then this message is forwarded to local AC side.
In like manner, after PE4 receives the message that CE40 sends, with leased-line communication method this message is forwarded to PE1 CE10 process similarly, repeat no more at this.
Can find out through the embodiment of the invention; Message getting into from an access via telephone line AC side on the PE equipment of source can be forwarded to the opposite end special line AC on the purpose PE equipment with private-line mode; And source messages is not done source MAC study and target MAC (Media Access Control) address is searched; Thereby both realized user's special line communication, saved the memory space of mac address table again.The broadcasting packet or the unknown unicast message that get into for other AC sides in the VSI can not be broadcast to special line AC side, and broadcasting packet or unknown unicast message for public network side in the VSI gets into can not be broadcast to special line AC side yet.Other AC that has so got rid of fully outside the special line AC is forwarded to special line AC with the service traffics of public network side PW, thereby carries out the flow intercommunication between the assurance special line AC.
Embodiment three
Present embodiment has been described under arbitrary VSI, is linked into the execution mode of realizing user's special line communication between the AC of different PE equipment, and wherein more than two the special line AC of special line group insert.
The scene that this embodiment is suitable for is; In the VPLS instance, need in specific group, carry out unconditional broadcasting sometimes to reach the purpose of data backup; And the access AC in these groups is not the common AC of instance, possibly be the special AC access device that articulates server.
In order to realize the utilization of this scene, present embodiment can be special line group customization broadcast service, and promptly the message in the special line group can be broadcast to all members in the group.
With the VPLS network architecture shown in Figure 7 is example; If among the CE60 and CE61 of the last connection of CE40, PE6 of the last connection of CE30, PE4 of the last connection of CE10, PE3 of the last connection of PE1; If the message that has a CE to send need be received by other CE; Then on these PE equipment, carry out in the VSI creating when configuration AC inserts the special line group, the AC member of this special line group is more than 2, but comprises the pairing AC of above-mentioned each CE.In order to differentiate with previous embodiment; Special line group with broadcast type in the present embodiment is called broadcasting special line group, and the special line group of broadcast type is distinguished with the special line group of unicast type in configuration to some extent, and is concrete; With PE6 is example; CE60 inserts PE6 through AC1, and CE61 inserts PE6 through AC2, can on PE6, dispose as follows:
Vsi vsi1 static//VPLS instance of establishment, instance is called vsi1
The signaling protocol of pwsignal ldp//appointment VPLS is LDP
The ID of vsi-id 500//appointment VPLS instance is 500
Peer 4.4.4.4//appointment VPLS opposite end PE4
Peer 3.3.3.3//appointment VPLS opposite end PE3
Peer 1.1.1.1//appointment VPLS opposite end PE1
Service-instance 1//AC of establishment, the AC sequence number is 1
The packaged type of encapsulation private-line global-id 1 qos 1 broadcast//appointment AC is overall private-line mode, and special line group ID is 1, and the QoS attribute is 1, and this special line is a broadcast type, and acquiescence will be in all opposite end broadcasting of VPLS
Xconnect vsi vsi1//this AC is tied to vsi1
Service-instance 2//AC of establishment, the AC sequence number is 2
The packaged type of encapsulation private-line global-id 1qos 1 broadcast//appointment AC is overall private-line mode, and special line group ID is 1, and the QoS attribute is 1, and this special line is a broadcast type, and acquiescence will be in all opposite end broadcasting of VPLS
Xconnect vsi vsi1//this AC is tied to vsi1
Wherein, but the QoS attribute is an arrangement, and expression is set to the indicated priority of this QoS attribute from the QoS priority of the flow that corresponding AC inserts.
Through AC1 and AC2 are broadcasted in VSI, then can all opposite equip.s in AC1 and AC and the VSI be arranged to a special line group, can also respectively all opposite equip.s of AC1 and AC and embodiment be arranged to a special line group according to the mode of embodiment two.
In like manner, on other PE equipment, carry out similar configuration, the special line ID of the broadcasting special line group that is disposed on each PE equipment is identical, but the opposite equip. that each PE goes up in the special line group that disposes can comprise all opposite equip.s, can also only comprise the part opposite equip..Through above-mentioned configuration, in the VPLS of control aspect instance, created several special lines AC, respectively on different PE equipment, but the VSI broadcasting table that belongs to same these PE equipment disposition of special line group is transmitted similar with embodiment two with embodiment one with the VSI special line.
For example, for the configuration requirement of group-network construction shown in Figure 7 and special line group, be 1 broadcasting special line group corresponding to special line group ID, the special line group broadcasting table that disposes on each PE equipment thes contents are as follows:
PE1: comprise the AC that connects local EC10, connect the PW of PE2, connect the PW of PE6;
PE3: comprise the AC that connects local EC30, connect the PW of PE1, connect the PW of PE4;
