Embodiment 2
The embodiment of the invention provides the creation method in a kind of Ethernet path, and is as shown in Figure 3, and this method comprises:
At first, the user opens the interface of creating the Ethernet LAN path, selects N professional MAC port then, wherein, and N＞1.
MAC (Medium/MediaAccess Control, medium access control) is also referred to as hardware address.
VB (Virtual Bridge; Virtual bridge); Be for the division of convenient management to management domain, the veneer at least one said professional MAC port place can also can be created the VB plate of VB for support for not supporting to create the transparent transmission plate of VB; The veneer that has only said professional MAC port place just can be created VB for can support to create the VB plate of VB the time.
The automatic veneer that calculates said professional MAC port place of webmaster does not support to create the transparent transmission plate of VB; Then VB information links to being provided with automatically; At this moment, need judge whether the veneer at other professional MAC port place supports to create VB, promptly forward step 301 to and continue to carry out judgement;
Particularly, when VB is created in the veneer support at said professional MAC port place, give tacit consent to this veneer and need create VB, at this moment, at first judge and whether support to create VB in the node on the said veneer; The strategy whether node supports to create VB is by the service creation demand of user according to oneself, and VB is created in the node support that can be provided with on the veneer, and certainly, the user also can adopt the setting of acquiescence, and the node that promptly is provided with on the veneer is not created VB; Then, when having a node to support to create VB on the said veneer, for example VB is created in the first node support, confirms the VB node on the said veneer, and creates the Ethernet path according to said VB node; In the scheme that the embodiment of the invention provides; Node on the veneer is divided into two kinds: non-VB node (not supporting to create the VB node) and VB node (supporting to create the VB node); But do not support all right and wrong VB of all nodes in all nodes on the veneer; At least need a VB node in all nodes, set up to the connection of multiple spot to realize multiple spot.
Here, between non-VB node, can only set up path between points, and the VB node is can set up multiple spot to the path between the multiple spot.
Need to prove; When the some nodes on the said veneer that the user is provided with are created VB for support, can create the Ethernet path according to the trunk link routing policy, said trunk link routing policy is provided with for the user; Particularly; Can also manual creation trunk link path can be carried out for using existing trunk link path, following dual mode can be adopted when creating the Ethernet path:
Mode one: use existing trunk link path;
At least one professional MAC port according to user's selection; And calculate available Trunk Link (trunk link) path automatically according to the node in the veneer at said professional MAC port place; Particularly; Confirm starting point and terminal point in the node in the veneer at said professional MAC port place, calculate all Trunk Link paths of connection source and terminal point then, as the service layer path of Ethernet LAN business.
Mode two: manual creation trunk link path;
Trunk link routing policy according to said user's setting; And the trunk link path trunk port on the said veneer of confirming according to said VB node and said user; Calculate the Ethernet path, all said trunk ports are connected in said Ethernet path and the quantity in said Ethernet path lacks 1 than the quantity of said trunk port.
Particularly, it is manual creation that the user selects Trunk Link routing policy, and webmaster jumps to Trunk Link automatically and creates the interface then; The user is according to the service creation demand of oneself; Select the trunk link path trunk port on the said veneer; The trunk port that webmaster is selected according to said user calculates available SDH path or wave division path automatically as the service layer path, accomplishes the establishment in Ethernet path, and all said trunk ports are connected in said Ethernet path and the quantity in said Ethernet path lacks 1 than the quantity of said trunk port; For example; When the trunk port of user's selection is 3, need set up two Ethernet paths this moment, can 3 trunk ports be coupled together.Accomplish after the establishment in Ethernet path, the establishment interface in Ethernet LAN path is gone back in the automatic redirect of webmaster.
According to the MAC port that the user selects, confirm all the available Ethernet paths in the said professional MAC port scope, comprise the Ethernet path of creating, the Ethernet path that webmaster calculates according to professional MAC port automatically according to the user.
Step 305 according to all said Ethernet paths, is preserved port attribute, port-mark, the path attribute information in every said Ethernet path, accomplishes the establishment of Ethernet LAN.
Alternatively, according to all Ethernet paths between the node of confirming, the attribute of the port in all Ethernet paths that user's configured port attribute, VLAN filter table and path self-defined information, port attribute are promptly confirmed; The VLAN filter table is the ports tab in Ethernet path, also can be called address tag; The path self-defined information is the title in path, defines the client's in this path information such as title.
After the user disposed the above-mentioned attribute of completion, webmaster was preserved, and the user issues the path of creating Ethernet LAN through webmaster, accomplished the establishment of Ethernet LAN.
The creation method in a kind of Ethernet path that the embodiment of the invention provides; Through at least one professional MAC port of selecting according to the user; Judge whether the veneer at said professional MAC port place supports to create VB; When VB is created in the veneer support at said professional MAC port place,, create internodal Ethernet path according to the trunk link routing policy that said user is provided with.With Ethernet service in the prior art to open efficient low; Ethernet service path management complicacy and fault location difficulty are compared; The scheme that the embodiment of the invention provides can only need to create once through webmaster, can activate the service, and improves the efficient of opening of Ethernet service; Realize the unified management in Ethernet service path, reduced management complexity; And the Ethernet path of creating what port report and alarm of taking up an official post can both directly have influence on this path, thereby can carry out fault location fast.
Need to prove in addition; The plus-minus VB node of the scheme supporting business that the embodiment of the invention provides; Be convenient to professional the seamlessly transitting and dilatation of existing network: on the basis of Ethernet LAN through adding some points; Include the service node of Access Layer in the Ethernet LAN management, form a new asymmetric Ethernet LAN path.
