Abstract

The invention relates to a label message control plane integration method based on MPLS L2VPN service, which comprises the following steps: (1) generating label items of a public network tunnel on a label message control plane of an MPLS L2VPN service; (2) integrating the label items of the public network tunnel via the control plane; (3) generating a label stack via the control plane; and (4) forwarding messages of the MPLS L2VPN service via a forwarding plane according to the information of the label stack. The label message control plane integration method adopting the structure has the advantages that one-time iteration integration of MPLS label message forwarding of an MPLS 2-layer virtual private network service can be fulfilled on the control plane via software, the information of the label stack used by the forwarding plane is sent directly, and iteration integration logic of the forwarding plane in forwarding label items such as FTN, VC FTN, NHLFE and ILM is not needed, so that the forwarding efficiency is greatly improved.

Description

Label packet chain of command integration method based on MPLS L2VPN business
Technical field
The present invention relates to NFV network function technical field of virtualization, the MPLS L2VPN label packet particularly relating to NFV turns Send out technical field, specifically refer to a kind of label packet chain of command integration method based on MPLS L2VPN business.
Background technology
In the legacy network devices of current main flow, such as router, switch, its MPLS (Multi-Protocol Label Switching, multiprotocol label switching) virtual private network in second layer network business, as it is shown in figure 1, i.e. MPLS L2VPN The forwarding of the MPLS label message of (Virtual Private Network, VPN) business, it forwards the letter of foundation Breath is generated by chain of command, then is issued to forwarding face, thus instructs forwarding face to carry out forwarding use, due to turning of legacy network devices Leaven dough and be limited to the requirement of such as forwarding chip etc hardware, thus commonly used successive ignition, the mode repeatedly searched, control The forwarding information that face issues can not be done directly the integration of L2VPN label packet label stack information, but issues such as FTN (FEC to NHLFE, FEC to NHLFE), VC (Virtual Ciecuit, virtual circuit) FTN, ILM (Incoming Lable Map, enters label mapping), NHLFE (Next Hop Lable Forwarding Entry, down hop label forwarding list item) turns Forwarding list item, as in figure 2 it is shown, forwarding face needs are iterated in these list items and integration completes forwarding logic.
Content of the invention
It is an object of the invention to overcome the shortcoming of above-mentioned prior art, providing one, to be capable of disposable iteration whole Merge the label packet chain of command integration side based on MPLS L2VPN business directly issuing the label stack information that forwarding face uses Method.
To achieve these goals, the present invention's has following composition：
Should comprise the steps based on the label packet chain of command integration method of MPLS L2VPN business：
(1) the label packet chain of command of MPLS L2VPN business generates the list item in public network tunnel；
(2) list item in described public network tunnel is integrated by the chain of command described in；
(3) chain of command described in generates label stack；
(4) message that forwarding face carries out MPLS L2VPN business by the information of described label stack forwards.
It is preferred that described list item includes FTN, VC FTN, NHLFE and ILM.
It it is preferred that the described list item by described public network tunnel is integrated, is specially：
By FTN, FEC (Forwarding Equivalence Class, forwarding equivalence class) is mapped to NHLFE, passes through MPLS is mapped to NHLFE by ILM.
It it is preferred that described generating forwards the label stack directly using, is specially：
By opcode (Operation Code, command code) command code, NHLFE is mapped to label, by described label It is integrated into label stack.
It is preferred that also comprise the steps between described step (3) and step (4)：
(3-1) chain of command described in issues described label stack to forwarding face.
Have employed the label packet chain of command integration method based on MPLS L2VPN business in this invention, to MPLS bis-layers The MPLS label message of virtual private networks business forwards and is i.e. completed the integration of disposable iteration by software at chain of command, directly issues The label stack information that forwarding face uses, it is not necessary to forward face at FTN, VC FTN, is iterated in the forwarding-table item such as NHLFE, ILM Integrate logic, thus significantly promote forward efficiency.
Brief description
Fig. 1 is the flow chart of the MPLS L2VPN label packet forwarding logic of prior art.
Fig. 2 is the logic diagram of the MPLS L2VPN label packet chain of command forwarding-table item of prior art.
Fig. 3 is the logic diagram of the MPLS L2VPN label packet chain of command integration process of the present invention.
Detailed description of the invention
In order to more clearly describe the technology contents of the present invention, carry out further below in conjunction with specific embodiment Describe.
In one embodiment, it is somebody's turn to do the label packet chain of command integration method based on MPLS L2VPN business, including as Lower step：
(1) the label packet chain of command of MPLS L2VPN business generates the list item in public network tunnel；
(2) list item in described public network tunnel is integrated by the chain of command described in；
(3) chain of command described in generates label stack；
(4) message that forwarding face carries out MPLS L2VPN business by the information of described label stack forwards.
In one preferably embodiment, described list item includes FTN, VC FTN, NHLFE and ILM.
In one preferably embodiment, the described list item by described public network tunnel is integrated, and is specially：
By FTN, FEC is mapped to NHLFE, by ILM, MPLS is mapped to NHLFE.
In one preferably embodiment, described generating forwards the label stack directly using, and is specially：
By opcode command code, NHLFE is mapped to label, described label is integrated into label stack.
In one preferably embodiment, also comprise the steps between described step (3) and step (4)：
(3-1) chain of command described in issues described label stack to forwarding face.
In a kind of specific embodiment, as it is shown on figure 3, comprise the following steps：
S1：Chain of command generates public network tunnel FTN, VC FTN, NHLFE and ILM list item；
S2：Chain of command completes the integration of public network tunnel FTN, VC FTN, NHLFE and ILM list item, and generating to forward directly makes Label stack；
S3：Chain of command issues the label stack of generation to forwarding face；
S4：The message that forwarding face directly uses label stack information to carry out MPLS L2VPN business forwards；
Have employed the label packet chain of command integration method based on MPLS L2VPN business in this invention, to MPLS bis-layers The MPLS label message of virtual private networks business forwards and is i.e. completed the integration of disposable iteration by software at chain of command, directly issues The label stack information that forwarding face uses, it is not necessary to forward face at FTN, VC FTN, is iterated in the forwarding-table item such as NHLFE, ILM Integrate logic, thus significantly promote forward efficiency.
