Description
Technical field
The present invention relates to the communications field, in particular to a kind of method for building up of service path, apparatus and system.
Background technology
Base station passed-back traffic is in addition to base station to the north-south flow between core net, in addition between base station and base station
East and West direction flow.Typical south is S1 business to flow in wireless network in correlation technique, and East and West direction flow is X2
Business.
Wireless backhaul based Carrying Scheme in correlation technique have two layers sending virtual private network (Virtual Private Network,
Referred to as VPN) tri- layers of sending virtual private network L3VPN of L2VPN+ and stratification L3VPN two schemes.For
L2VPN+L3VPN schemes, Fig. 1 is according to L2VPN+L3VPN service bearers scheme in correlation technique of the present invention
Schematic diagram, is shown in Fig. 1, wherein, eNodeB is that the X2 business between base station network element, base station needs to be turned by bridge contact
Hair, the purpose for the arrangement is that in order to avoid setting up the full connection L2VPN tunnels between base station, simplifying network.But have the disadvantage
The forwarding nearby of base station East and West direction flow can not be realized.For stratification L3VPN schemes, Fig. 2 is according to phase of the present invention
Pass technology middle-levelization L3VPN service bearer schemes, are shown in Fig. 2, the problem of existing is similar with L2VPN+L3VPN,
East and West direction flow between base station is required for being forwarded by default gateway, and reason is that generally access PE only has and arrived
The route of full IP packet-based core networks (Evolved Packet Core, referred to as EPC), without other accesses PE
Route, this way can reduce the requirement to access device routing table ability, reduce networking cost.

With reference to the present invention is described in detail according to an alternative embodiment of the invention：
This alternative embodiment is related to the forwarding unit (PE equipment) for having run MPLS/MPLS-TP L3VPN and control
Device processed, realizes that service path on demand is set up by interacting for forwarding unit and controller.
As shown in figure 4, relative to legacy network, this embodiment introduces controller, passing through concentration of the controller to network
Management and forwarding unit realize present disclosure with interacting for controller.The centralized management of controller includes：Route pipe
The functions such as reason, route issue, path computing.
Fig. 9 is the network architecture figure according to alternative embodiment of the present invention, as shown in figure 9, introducing connection in PE equipment
The reporting module 90 (reporting module corresponded in Fig. 8) of request is set up, including：
S21, CE1 equipment are using the IP address of itself as source IP, using the IP address of CE2 equipment as purpose IP, send report
Text gives PE equipment, because PE equipment original state does not have CE2 routing iinformation in the prior art, therefore on road
The outlet of this business is can not find out in table and then forwarding can not be realized；
Business transmission request is sent to connection and sets up request reporting module by S22, PE1, and thus module reports controller,
Connection is set up in request；
Controller receives connection and set up after request, performs following steps：
The routing table of each PE equipment in S31, management network, including VPN route and PE between CE and PE
Public network route between PE；
S32, receives the connection foundation request that PE equipment is reported, and connection sets up request and contains source node, source IP, mesh
The information such as IP；
S33, controller retrieves routing table according to purpose IP, finds corresponding purpose network element, and in source node and purpose
Path is set up between node, path can be MPLS tunnels or MPLS-TP tunnels.
S34, carries out route issue, by the VPN route learnt between PE and CE between the PE for having path to connect
Other far-end PEs are published to, the function of similar distributed routing protocol is realized.As the PE1 routes for learning to arrive CE1 (can
To be learnt by dynamic routing protocol or be configured by static routing), PE1 route can be distributed to other by controller
Required PE equipment.If the tunnel connection set up between PE2 and PE1, it is possible to think between PE1 and PE2
Issue route mutually is needed, the CE1 acquired on PE1 route will be distributed to PE2 by controller.
S35, passage path is set up and route issue, and the connection between PE1 and PE2, which is set up, to be completed.
Foregoing invention is described below LTE base station business is carried in packet network, X2 service paths between base station are set up on demand
Specific embodiment, Figure 10 is that X2 service paths set up schematic diagram between the base station according to alternative embodiment of the present invention, is such as schemed
Shown in 10.
There is the demand of East and West direction flow between base station 1 and base station 2, but bearer network does not have in advance for the foundation of the two base stations
Connection is, it is necessary to the path connection set up by business-driven or service request between access PE1 and access PE2.
The process of setting up of service path includes：
S41, configuration access PE1 interface IP and the IP of base station 1 are in the same network segment, PE2 interface IP and base station 2
IP in the same network segment.
S42, configuration access PE1 to base station 1 static routing, configuration access PE2 to base station 2 static routing.
S43, controller obtains all PE of the whole network routing iinformation, forms global routing table.
S44, base station 1 is issued to the IP messages of base station 2, and the source IP that message is carried is the IP address of base station 1, purpose
IP is the IP address of base station 2.
S45, access PE1 receives the service message that base station 1 is sent, because PE1 only has the route to base station 1, not
There is the route to base station 2, therefore can not find out routing table, this business feeding service path is set up into request reporting module.
S46, reporting module will be sent to controller in request.
S47, controller receives the business foundation request that access PE1 is reported, and request content contains source IP and purpose IP
Information, it is access PE2 that controller finds target network element by purpose IP.
S48, controller sets up a tunnel from PE1 to PE2, and tunnel uses shortest path, without being saved by other
Point detours.
S49, issue is route controller mutually between PE1 and PE2, and such PE1 just obtains the route of base station 2,
Same PE2 also obtain the route of base station 1.
Connection between base station 1 and base station 2 is set up, and the service message of subsequent base stations 1 to base station 2 directly can pass through this
Path is forwarded, without sending controller on again.
It is workable from embodiment as can be seen that handling process of the present invention is succinct, have in packet network stronger
Practical value.
Created a mechanism by the service path of the present embodiment, can be real in MPLS/MPLS-TP L3VPN networks
Now set up by the path on demand of business-driven.Existing service bearer mechanism is changed, i.e., only pre-establishes path ability
Service bearer is realized, realizes by business-driven to set up connection.Reach that business, with carrying the effect separated, makes simultaneously
The connection number for obtaining bearer network is substantially reduced, and improves network efficiency.So that operator can be with more flexible, more accurate, more just
Prompt realizes service fulfillment operation.
It should be noted that above-mentioned modules can be by software or hardware to realize, for the latter, Ke Yitong
Cross in the following manner realization, but not limited to this：Above-mentioned module is respectively positioned in same processor；Or, above-mentioned module distinguishes position
