Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, is not whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.

Traditional network is made up of forwarding unit, and control protocol is applied on each forwarding unit, such as Routing Protocol, multiprotocol label switching (MultiProtocol Label Switching, MPLS) agreement etc..User by order line can configure the related parameter of control protocol and control protocol on forwarding unit, configuration result can also be forwarded into each forwarding unit by webmaster.In addition, webmaster and forwarding unit also can be directly by management agreements, such as netconf, (Simple Network Management Protocol, SNMP etc. are interacted Simple Network Management Protocol.

As shown in fig.1, the main application scenarios of the embodiment of the present invention are software defined network (Software Defined Network, SDN), SDN framework includes controller and forwarding unit, and by forwarding unit composition data network.Management information or control information are issued to forwarding unit by management agreement or control protocol and go execution by controller, and the presence of controller causes the deployment of network and configures more intelligence and simplify.

In SDN, management agreement can be passed through between controller and forwarding unit, such as netconf, the interaction configuration information such as SNMP or warning information, control information can also be interacted by control protocols such as PCEP, BGP, for example, forwarding unit is handed down in the path of calculating by controller by PCEP, forwarding unit collection network topology information reports controller by BGP.

Specifically, path-calculating element (Path Computation Element, PCE) is a kind of centralized control node, unified business interface is naturally suitable as.Current path calculates communication protocol (Path Computation Element Communication Protocol, PCEP) agreement is mainly label switched path (the Label Switching Path of definition, LSP) related message, for supporting that LSP concentration calculates road and the LSP correlation function characteristics such as LSP are set up in controller triggering.

PCEP agreements are as the south orientation control protocol between controller and transponder, in expanded definition transmission topology information (PCE-LS), issue label list item information, tunnel (Tunnel) information, and the message that will support more non-LSP.

Bgp protocol can also facilitate the to be extended as the south orientation controller protocol between a kind of controller and transponder, support to carry be not only route message.Such as, BGP-LS extends bgp protocol transmission topology information.

The application is preferred embodiment described in detail below in conjunction with the accompanying drawings.

As shown in fig.2, the embodiment of the present invention provides a kind of method for setting up interface group, following steps are specifically included：

Step 200：Controller receiving interface group creates instruction, and interface group, which creates instruction, to be used to indicate that controller creates interface group using control protocol control forwarding unit:.

Step 210：Controller transmission interface group creates message to forwarding unit, and interface group, which creates message, to be used to notify forwarding unit to create the interface group for including at least one interface, and interface group creates the information that message carries each interface in interface group.

Alternatively, interface group creates the mark that message also carries interface group, or controller receives the mark for the interface group that forwarding unit is sent.

Refering to the schematic diagram for shown in Fig. 3 A and Fig. 3 B, being extension PCEP agreements in the embodiment of the present invention.

Specifically, extension IfGroup PCE Initiate message, according to the newly-built TLVs of PCEP agreements, can support to create and delete IfGroup, wherein important object is IFGROUP.

Pass through existing PCEP agreements in IfGroup Message<SRP>Flag bit in object, which is distinguished, to be created or updates (ifgroup-create-or-update) or delete (ifgroup-delete).

Specifically, refering to shown in Fig. 3 A and Fig. 3 B, interface group creates the mark IfGroup Identifier that message carries interface group, and in interface group each interface information Interface Sub TLVs, each Flag can also be carried.

Wherein, IfGroup Identifier are distributed by controller, the allocative decision can mark allocation rule of the controller based on network level be allocated or controller based on equipment mark distribution require be allocated.

Alternatively, interface group creates message and also carries the corresponding logical type of interface group, i.e. Flag1, wherein, logical type is any one in ethernet-trunk, vlanif.

Forwarding unit determines that logical type is ethernet-trunk or vlanif, then the logic interfacing for setting up interface group accordingly is ethernet-trunk or vlanif.

If the logical type without specified interface group, NULL, i.e. a group interface binding are defaulted as, or can also indicate the type of current new interface group for NULL in Flag1.

Alternatively, interface group creates the ability information that message also carries interface group, that is Flag2, ability information includes interface group, and whether holding load is shared, whether supports multicast, whether switching main interface and spare interface between is supported, if support to judge any one in the interface transmission in ethernet-trunk logic interfaces.

Alternatively, interface group creates message and also carried for indicating whether forwarding unit generates the configured information of forwarding-table item, i.e. Flag3 for interface group.

Wherein, the information of each interface includes device identification and the interface correlated identities information of forwarding unit in interface group.

Wherein, interface correlated identities information includes any one in the interface name of the interface, the adjacent body index of the interface index of the interface, the interface, the adjacent body mark of the interface.For example, the interface correlated identities information includes device identification and IfName, either the interface correlated identities information, which includes device identification and Ifindex or the interface correlated identities information, includes device identification and adjindex.

Specifically, as knowable to Fig. 3 A and Fig. 3 B, interface group creates in the IFGROUP objects in message and includes an an IFGROUP-Identifier TLV and IFGROUP-IfMember TLV.

When controller issues interface group first creates message, forwarding unit is to give tacit consent to the message for creating type, and when having the message of the IfGroup Identifier under second, forwarding unit is to be defaulted as interface group membership's new information.

The mark and control mark of interface group are carried in IFGROUP-Identifier TLV, such as Flag1, Flag2 and Flag3.

The total interface information about firms of interface group to be created is carried in IFGROUP-IfMember TLV.

Alternatively, controller can be sent configures message to forwarding unit for the first of interface group, first configuration message includes the mark and the first rule of interface group, first configuration message is used for each interface for indicating that the first rule is configured in the corresponding interface group of mark of interface group by forwarding unit, first rule includes default application strategy, such as BGP Flow Spec, or default message forwarding discrepancy information, for example redirect and indicate.

Specifically, after controller transmission interface group establishment message to forwarding unit, may apply in following scene：

For example, by taking BGP flow spec application strategies as an example, i.e. BGP flow spec define set of rule strategy and are issued to equipment by bgp protocol, and prepare to be configured on a group interface of some forwarding unit.

Specifically, controller is first to need to set up interface group, refering to shown in step 200 to step 210, controller issues interface group and creates message, it is that 12, Flag1 is NULL to carry IfGroup Identifier, and Interface Sub TLVs include interface 1, interface 3 and interface 5.Forwarding unit receives controller transmission interface group and created after message, forwarding unit determines that the interface included in interface group is interface 1, interface 3 and interface 5 according to the information of each interface in interface group, corresponding relation between the interface included in the mark and interface group of setting up interface group, that is the corresponding interface 1 of mark 12, interface 3 and the interface 5 of interface group, the logical type of the interface group is NULL, it is not necessary to set up corresponding logic interfacing.

After the completion of interface group establishment, i.e. controller issues interface group and created after message, controller issues the mark 12 of BGP Flow Spec and interface group using bgp protocol, after forwarding unit side is received, according to the mark 12 of interface group, the corresponding interface 1 of mark 12, interface 3 and the interface 5 of mark 12 correspondence which interface, the i.e. interface group of interface group are determined, then BGP Flow Spec are configured at interface 1, interface 3 and interface 5.

In another example, interface group creates message and also carries SID, and the SID is used to identify interface group.For the application scenarios of redirect ID in BGP Flow Spec, first rule walks the interface group specified for default message forwarding discrepancy information, i.e. forced message, can now use the mark of interface group, also SID can be used, it is determined that needing the interface group being redirected to.Specifically, usual message forwarding is that the forward table generated according to Routing Protocol is forwarded, but if it is desired to specify message to walk specific road warp, it is necessary to configuration is redirected by docking port group, therefore, redirect and just refer to that forced message walks the interface specified or interface group.

Here the first rule is come in and gone out by default application strategy and the forwarding of default message exemplified by information, in addition, the first rule may also include the possible configuration that other are directed to interface group.

In addition, also proposed in the embodiment of the present invention, how docking port group membership is updated.

Specifically, after controller transmission interface group establishment message to forwarding unit, controller sends interface group membership's new information for interface group, and interface group membership updates messages to includes the mark and interface fresh information of interface group less；

Interface fresh information includes at least one in following information：

The information of at least one interface deleted is needed in the information of at least one interface increased newly in the information of each the current interface included in interface group, interface group, interface group；

Interface group membership new information is used to indicate that forwarding unit updates the interface message included in interface group.

Combined and understood by above-mentioned message, interface group membership new information can create the form of message using interface group completely, now only need forwarding unit to ignore Flag, the mark of interface group is constant, the message of original total interface member is replaced with the message of all newest interface members

For example, when issuing interface group establishment message for the second time, forwarding unit finds there is the IfGroup that 12 are identified with IfGroup Identifier, now replaces original interface member using the total interface member in the IFGROUP-IfMember TLV in second of message.

Alternatively, controller directly transmits the information of at least one newly-increased interface, or needs the information of at least one interface deleted.Now, forwarding unit directly increases or deleted the interface member in corresponding interface group according to the message.

After controller sends interface group membership's new information for interface group, controller is if it is determined that when the first rule configuration is on each interface in interface group, then need to send the configuration update message for interface group, the configuration update message is used for the interface for indicating that forwarding unit determines the interface or deletion increased newly according to interface group membership new information, and the first rule is configured to newly-increased interface, or the interface de-provision first of deletion is regular.For example, need to be directed to the renewal that interface group 1 enters line interface member, included in former interface group 1 and interface 5, interface 9 and interface 13 are included in interface 5, interface 9 and interface 12, the interface group 1 after renewal, that is, delete interface 12, interface 13 is increased newly, if interface group 1 has been configured with rule 2, now, controller needs to retransmit a configuration update message, allow forwarding unit to be the configuration rule 2 of interface 13, be the de-provision rule 2. of interface 12

Further, the embodiment of the present invention also supports the deletion of docking port group for the extension of PCEP agreements.

Specifically, after controller transmission interface group establishment message to forwarding unit, alternatively, controller receives the interface group deletion instruction that user sends, and interface group deletion instruction is used to indicate that controller controls forwarding unit to delete interface group.

Controller transmission interface group deletes message to forwarding unit, and interface group deletes the mark that message carries interface group, for indicating that forwarding unit deletes the corresponding interface group of mark of interface group.

Alternatively, controller is received after the interface group deletion instruction that user sends, and send interface group delete message to forwarding unit before, controller is if it is determined that when the first rule is configured on each interface in interface group, alarm information is sent to user, alarm information is used to point out user to deleting interface group to confirm, to alert the deletion error that user is likely to occur.

Alternatively, when controller determines that the first rule is configured on each interface in interface group, send configuration deletes message to forwarding unit, message is deleted in configuration to be used to indicate forwarding unit by the rule of interface group de-provision first, i.e. first de-provision is in the first rule of required deletion interface, then is deleted.
