In addition, above-mentioned configuration information, the virtual unit arranging on specifically referring on PE equipment access device, also claims virtual machine to carry out the relevant configuration information of flow control, detection etc., such as qos policy etc.And in the large double layer network based on VPLS technology, this configuration information can be called VPLS configuration, in the large double layer network based on SPB technology, this configuration information can be called SPB configuration, in the large double layer network based on EVI technology, this configuration information can be called EVI configuration, and in the large double layer network based on VXLAN technology, this configuration information can be called VXLAN configuration.
Wherein, different application scene, the specific configuration information of heterogeneous networks can be different, and concrete configuration process also can be different, being embodied in this and being not particularly limited of configuration.
For convenience of description, in the embodiment of the present invention, take the large double layer network based on VPLS technology as example, be example take access server as access device simultaneously, embodiment of the present invention technical scheme is described.As shown in Figure 1, large double layer network comprises access server 1 and access server 2, be provided with virtual unit 1, virtual unit 2 and virtual unit 3, and access server 1 is connected in this access server 1 with PE equipment 2; In access server 2, be provided with virtual unit 4, and access server 2 is connected with PE equipment 3.In addition between PE equipment 2 and PE equipment 3, be connected by tunnel.Further, between PE equipment 2 and PE equipment 1, be connected by tunnel, between PE equipment 3 and PE equipment 1, be connected by tunnel.It will be understood by those skilled in the art that in large double layer network, between PE equipment, connect by the tunnel of setting up just, realize between access device and can carry out by PE equipment the connection of double layer network, form so-called large double layer network.
In the embodiment of the present invention, for the flow on each virtual unit carries out Service control, on PE equipment, be provided with the configuration of the corresponding virtual unit virtual unit of PE equipment connection (with), referred to herein as traffic monitoring configuration, and this traffic monitoring configuration specifically includes but not limited to qos policy.In the present embodiment, not to the concrete setting up procedure configuring, the particular content of configuration is particularly limited, and its concrete configuration process and deploy content repeat no more.
As shown in Figure 2, the moving method of configuration information specifically can comprise the following steps:
In step 201 and step 202, described configuration information specifically can be included as PE equipment with the configuration issuing on virtual unit binding or corresponding interface, can be for example the configurations such as qos policy, the specifically configuration corresponding with the MAC Address of virtual unit of this configuration.Therefore, the configuration information described in the present embodiment, specifically can comprise the MAC Address of virtual unit, and relevant configuration, such as qos policy etc.Can elaborate below.
In step 201, PE equipment Inspection disconnects to connected virtual unit, particularly, when the interface Down binding with virtual unit detected, can think that this virtual unit needs migration, now can be by the configuration information corresponding with virtual unit from configuring with it, send on other PE equipment, so that while receiving the virtual unit of this migration on the access server of other PE equipment connection, can be configured based on this configuration information, reduce human configuration process, can guarantee the consistency of configuration simultaneously, avoid the problem of the rear configuration of virtual unit migration inconsequent to occur.
In the present embodiment, when other PE equipment is being received after the configuration information that virtual unit is corresponding, the PE equipment that receives this configuration information is determined when virtual unit moves to the access server being connected with himself, and this configuration information can be set on equipment of itself, guarantees the proper communication of virtual unit.Particularly, receive the PE equipment of configuration information, can determine whether virtual unit moves on the access server self connecting according to MAC Address corresponding to virtual unit, because virtual unit moves to after access server, the PE equipment that need to be connected with this access server connects, and therefore, this PE equipment can be learnt the MAC Address of virtual unit, thereby can with configuration information in MAC Address comparison, move into determining whether.
In addition, receive the PE equipment of configuration information, if in the default time, for example 5s, determine virtual unit do not move into self connect access server, can delete this configuration information.This default time can be set according to actual needs.
In sum, in the embodiment of the present invention, in the time that the virtual unit arranging in an access server moves to another access server, PE equipment sends configuration information corresponding to virtual unit by other PE equipment in network, thereby in the transition process of virtual unit, the configuration information that Autonomic Migration Framework virtual unit is corresponding, the workload of avoiding existing employing manual configuration to bring, also can guarantee that virtual unit moves the consistency of the configuration of front and back simultaneously.
Below in conjunction with the application scenarios shown in Fig. 1, the embodiment of the present invention is further elaborated, as shown in Figure 3, the moving method of the configuration information that the embodiment of the present invention proposes comprises the following steps:
Wherein, in the time of the port DOWN being connected with virtual unit on PE equipment, the disconnection that is connected between virtual unit and this PE equipment is described, now virtual unit may move to another access server.
In this step, being connected while disconnection between virtual unit and PE equipment, actual conditions might not be that this virtual unit moves to another access server, also be likely the disconnection that is connected between the virtual unit that causes due to other reason and PE equipment, the disconnection that is connected of breaking down between the virtual unit that caused and PE equipment as virtual unit.But, no matter be that what reason causes the disconnection that is connected between virtual unit and PE equipment, in the embodiment of the present invention, PE equipment all can think that virtual unit may need to move to another access server, and the technical scheme providing in the embodiment of the present invention is provided, adopt subsequent step to carry out relevant treatment.
The process that moves to access server 2 take virtual unit 3 from access server 1 describes as example, when virtual unit 3 moves to access server 2 from access server 1, being connected between virtual unit 3 and PE equipment 2 will disconnect, and PE equipment 2 can detect the disconnection that is connected between virtual unit 3 and this PE equipment 2, and knows that this virtual unit 3 may move to another access server.
Wherein, PE equipment need to send to configuration information corresponding virtual unit other all PE equipment in network.For example, under the application scenarios shown in Fig. 1, PE equipment 2 need to send to PE equipment 1 by the configuration information of virtual unit 3 correspondences by tunnel, and PE equipment 2 need to send to PE equipment 3 by the configuration information of virtual unit 3 correspondences by tunnel.
In the correlated process of VPLS technology, on PE equipment, also need to configure VSI(Virtual Switch Instance, virtual switch instance), and by corresponding MAC Address and the port of this VSI binding virtual unit.On this basis, in the embodiment of the present invention, PE equipment can also enable configuration information from shift function in advance under VSI corresponding to virtual unit.In actual applications, PE equipment can all enable traffic monitoring configuration information from shift function in advance under VSI corresponding to all virtual units, as PE equipment 2 enables respectively configuration information from shift function under the VSI of the VSI of the VSI of virtual unit 1 correspondence, virtual unit 2 correspondences, virtual unit 3 correspondences; Or PE equipment also can enable configuration information from shift function in advance based on strategy under VSI corresponding to the virtual unit of specifying, as 2 of PE equipment enable configuration information from shift function under the VSI of virtual unit 3 correspondences.
Based on this configuration information from shift function, PE equipment sends in the process of the configuration information that virtual unit is corresponding to other PE equipment in network, PE equipment, in the time knowing that virtual unit need to move to another access server, need to judge under the VSI that this virtual unit is corresponding whether enabled configuration information from shift function; If do not enable configuration information from shift function, need to process according to existing execution mode, this processing procedure does not repeat them here; If enabled configuration information from shift function, PE equipment is carried out above-mentioned steps 302, and PE equipment sends configuration information corresponding to virtual unit to other all PE equipment.
It will be appreciated by those skilled in the art that, in practical application, in the time that virtual unit moves, the PE equipment distribution configuration command that also can connect to virtual unit, to enable this configuration information from migration, like this, the virtual unit that can avoid causing because of fault is connected with PE to disconnect and causes PE equipment to send configuration information to other PE equipment.
In the correlated process of VPLS technology, PE equipment need to, by tunnel by sending to other all PE equipment in network with the MAC Address of the virtual unit of this PE equipment connection, with the MAC Address at other this virtual unit of PE equipment learning, be safeguarded MAC address entries; In the time that being connected between virtual unit and this PE equipment disconnects, PE equipment need to send address to other all PE equipment in network by tunnel and reclaim message, so that other PE equipment is deleted the MAC Address of this virtual unit from the MAC address entries of self maintained.Based on said process, in the embodiment of the present invention, can reclaim message to address expands, in the time that PE equipment need to send configuration information corresponding to virtual unit to other PE equipment in network by tunnel, configuration information corresponding virtual unit can be carried on to address reclaims in message, be that reclaim in message the address that PE equipment sends to other PE equipment in network, carry the configuration information that virtual unit is corresponding.Wherein, relevant configuration specifically includes but not limited to qos policy, in subsequent process, describes as an example of qos policy example.
In the embodiment of the present invention, by reclaiming in message and expand qos policy TLV(Type Length Value, type lengths values in address) field, to carry by this qos policy TLV field the qos policy that virtual unit is corresponding.As shown in Figure 4, for the schematic diagram of the qos policy TLV that expands in the embodiment of the present invention, this qos policy TLV comprises traffic classification field (traffic classifier List TLV), traffic behavior field (traffic behavior List TLV) and spreading parameter field (Optional Parameters); Wherein, the traffic classification information of this traffic classification field for carrying the qos policy that virtual unit is corresponding, this traffic behavior field is for carrying the traffic behavior information of stating qos policy that virtual unit is corresponding, this traffic classification information and traffic behavior information form qos policy jointly, the content of traffic classification information and traffic behavior information is same as the prior art, repeats in this step.
In specific implementation process, if include the MAC Address that virtual unit is corresponding in configuration information, address is reclaimed in message and can not carried address field (Address List TLV), and this address field is for carrying the MAC Address that virtual unit is corresponding; But, if do not comprise the MAC Address that virtual unit is corresponding in configuration information, reclaim in message address also needs to carry address field (Address List TLV), this address field is for carrying the MAC Address that virtual unit is corresponding, as shown in Figure 4, reclaim the schematic diagram of message for carrying the address of address field (Address List TLV).
In the embodiment of the present invention, other PE equipment is being received after the configuration information that virtual unit is corresponding, determine that this virtual unit moves to the access server that equipment of itself connects, and arranges the configuration information that this virtual unit is corresponding on equipment of itself if utilize the MAC Address that this virtual unit is corresponding.
In addition, other PE equipment is being received after the configuration information that virtual unit is corresponding, if determine that within the default time virtual unit does not move to the access server that equipment of itself connects, delete this configuration information, the configuration information that this virtual unit is corresponding need to be set on equipment of itself.
It should be noted that, in above-mentioned processing procedure, in the time that virtual unit moves to the access server of other PE equipment connection, the PE equipment that this virtual unit will be connected with the access server moving to connects, and now this PE equipment can be known the MAC Address of the virtual unit being connected with self.Based on this, PE equipment is being received after the configuration information that virtual unit is corresponding, if the MAC Address in this configuration information is with identical with the MAC Address of the virtual unit of PE equipment connection, PE equipment can determine that virtual unit moves to the access server that equipment of itself connects, otherwise this PE equipment can determine that virtual unit does not move to the access server that equipment of itself connects.
Under the application scenarios shown in Fig. 1, PE equipment 2 sends to PE equipment 1 by tunnel by the configuration information of virtual unit 3 correspondences, and by tunnel, the configuration information of virtual unit 3 correspondences is sent to PE equipment 3.PE equipment 1 is being received after the configuration information of virtual unit 3 correspondences, in Preset Time, utilize the MAC Address of virtual unit 3 correspondences to determine that virtual unit 3 does not move to the access server that PE equipment 1 connects, directly abandon the configuration information of receiving, the configuration information of these virtual unit 3 correspondences is not set.PE equipment 3 is being received after the configuration information of virtual unit 3 correspondences, in Preset Time, utilize the MAC Address of virtual unit 3 correspondences to determine that virtual unit 3 moves to the access server 2 that PE equipment 3 connects, and now arranges the configuration information of these virtual unit 3 correspondences on PE equipment 3.
In the embodiment of the present invention, other PE equipment receives the process of the configuration information that virtual unit is corresponding, specifically comprises: other PE equipment receiver address reclaims message, reclaims message obtain the virtual unit configuration information wherein carrying by parse addresses.
Particularly, other PE equipment reclaims message and parses qos policy TLV field from address, from the traffic classification field of qos policy TLV field, obtain the traffic classification information of qos policy, from the traffic behavior field of qos policy TLV field, obtain the traffic behavior information of qos policy.Afterwards, other PE equipment is based on traffic classification information and traffic behavior information structure qos policy.
