The mark of mark and LSP layers including OCH layers.
In a kind of possible design, abstract topology, which obtains request, can also include basic primitive (message), such as substantially
Primitive can be abstract strategy, and abstract strategy is white is abstract, grey is abstract or black is abstracted.Wherein, white is abstract does not take out
As MDSC possesses all bottom-layer network information, and MDSC itself can complete path computing and establish an end-to-end path.Black
Abstract that a domain is abstracted as into a dummy node, MDSC needs to give the requirement of PNC path computations, and PNC is responsible for industry in domain
The establishment of business, MDSC are responsible for cross-domain coordination.Under black is abstract, MDSC can only obtain some boundary node information, can not be appointed

Breath.
In a kind of possible design, basic primitive can be Optimality Criteria or topology-level constraints.
It should be noted that MDSC can send different abstract topologys to multiple PNC simultaneously obtains request.With reference to figure 2
Shown, MDSC can send the first abstract topology to PNC1 and obtain request, and the first abstract topology obtains request and can serve to indicate that
PNC1 abstract networks A OCH layers.MDSC can send the second abstract topology to PNC2 and obtain request, and the second abstract topology obtains
Request can serve to indicate that PNC2 abstract networks B LSP layers.MDSC can send the 3rd abstract topology to PNC3 and obtain request,
3rd abstract topology obtains the ODU layers that request can serve to indicate that PNC3 abstract networks C.In addition, the first abstract topology is obtained and asked
The first abstract strategy can also be included by asking, and it is abstract that the first abstract strategy can serve to indicate that PNC1 carries out white.Second abstract opens up
The second abstract strategy can also be included by flutterring acquisition request, and the second abstract strategy can serve to indicate that PNC2 progress grey is abstracted.The
Three abstract topologys, which obtain request, can also include the 3rd abstract strategy, and the 3rd abstract strategy can serve to indicate that PNC3 carries out black
It is abstract.
502nd, PNC receives the abstract topology that MDSC is sent and obtains request, and obtains request to bottom according to the abstract topology
The protocol layer of physical resource is abstracted.
When the abstract topology that PNC receives MDSC transmissions obtains request, the abstract topology can be parsed and obtain request, obtained
The mark of the protocol layer of abstract bottom physical resource is treated, and the mark of the protocol layer obtained according to parsing is to bottom physical resource
Protocol layer be abstracted.
Optionally, PNC may further determine that abstract topology obtains the abstract strategy in request, and according to the abstract strategy
Bottom physical resource is abstracted.
For example, as shown in Fig. 2 if MDSC sends abstract tactful to be white abstract, PNC1 only abstract network A to PNC1
Whole nodes, such as node A1, A2, A3, A4, A5, A6 and A7.If MDSC takes out to the abstract strategy that PNC1 is sent for grey
As then PNC1 only abstract network A boundary nodes, such as node A1, A6 and A7.If MDSC is to the abstract strategy that PNC1 is sent
Black is abstracted, then network A is abstracted as a point by PNC1.
Optionally, PNC can obtain corresponding parameter according to the link parameter of protocol layer or the solicited message of node parameter.
For example, if the solicited message of node parameter includes the attribute information of LSP nodes, PNC can be each in LSP layers by inquiring about
The configuration file of LSP nodes obtains the attribute information of each LSP nodes.In addition, PNC can also be according to Optimality Criteria or topology-level
Constraints obtains corresponding topology information.
503rd, PNC sends abstract topology information to MDSC.
It should be noted that PNC is obtained according to abstract topology when asking to be abstracted the protocol layer of bottom physical resource,
Abstract topology information can be obtained, being abstracted topology information includes the abstracted information of the protocol layer indicated by the mark of protocol layer.Example
Such as, abstract topology information can include the annexation in OCH layers between the node identification of each OCH layers and each node.
Optionally, abstract topology information can include the link parameter or node parameter of protocol layer, and/or PNC is according to excellent
Change the corresponding topology information that criterion or topology-level constraints obtain.
504th, MDSC receives the abstract topology information that PNC is sent, and abstract view is obtained according to abstract topology information.
Abstract view is used to state PNC to the abstract of the protocol layer of bottom physical resource.
For example, with reference to shown in figure 2, it is assumed that network A is packet network, network B is OTN networks, network C is packet net
Network.If MDSC requires that PNC1, PNC2 and PNC3 progress grey are abstract and PNC1, PNC2 and PNC3 are abstracted OCH layers and LSP
Layer, then the abstract view that MDSC is got according to abstract topology information can be as shown in Figure 6.Wherein, network A and network C are present
LSP layers, but OCH layers are not present, there is OCH layers in network B, but LSP layers are not present.
Assuming that network A is OTN networks, network B is packet network, network C is OTN networks.On the one hand, if MDSC is required
PNC1 and PNC3 carries out white to OCH layers and is abstracted, and carrying out grey to ODU layers is abstracted；On the other hand, if MDSC requires PNC2 to thing
It is abstract to manage layer progress white, grey is carried out to LSP layers and is abstracted, then the abstract view that MDSC is got according to abstract topology information can
With as shown in Figure 7.That is the mark and annexation of whole nodes corresponding to PNC1 and PNC3 difference included by the OCH layers of network
Show, the mark of the fringe node included by the ODU layers of corresponding network and annexation have and shown respectively by PNC1 and PNC3
Go out.The mark and annexation of whole nodes included by the physical layer of network corresponding to PNC2 are shown, corresponding to PNC2
The mark and annexation of fringe node included by the LSP layers of network are shown.
Thus, the embodiment of the present application sends abstract topology to PNC by MDSC and obtains request, to indicate PNC to bottom thing
The protocol layer of reason resource is abstracted；Then, MDSC receives the abstract topology information that PNC is sent, and according to abstract topology information
Obtain the abstract view of the protocol layer of bottom physical resource.Abstract method compared to ietf specification only can be to node/link
Progress white is abstract, grey is abstract and black is abstracted, i.e., does not provide specific abstract method to specific network.The embodiment of the present application
The layer information of intra-node protocal layers can be further taken out, the abstract method of ietf specification is enriched, improves MDSC
To network and the control ability of business, the establishment and management of cross-domain end-to-end business can be better met.
