Technology and problem of the existing technology based on the above background, referring to Fig. 3, the embodiment of the present invention provides a kind of net
Network alarm method, this method specifically include:
301, physical network controller PNC obtain network failure information, network failure information include one below or
It is multinomial: node failure information and link failure information.
302, network failure information matches virtual network topology is generated virtual faults information and virtual faults information by PNC
Affiliated virtual information；Wherein, virtual information belonging to virtual faults information includes below one or more: virtual faults letter
Virtual network belonging to virtual link belonging to breath and virtual faults information.
It is detailed, 3021, PNC is when determining that network failure information is node failure information, determine the node that breaks down, and
According to virtual link belonging to the corresponding virtual faults information of network failure information matches virtual network topology generation node, node
And virtual network belonging to node.
3022, when PNC determines that network failure information is link failure information, the link to break down is determined, and according to net
Network fault message matching virtual network topology generates virtual network belonging to the corresponding virtual faults information of link and link.
After step 302 further include: PNC determines that virtual faults information belongs to the fault message of physical network topology, then
Voluntarily handle network failure information.
303, PNC determines that virtual faults information belongs to the fault message of virtual network topology, then by virtual faults information with
And virtual information belonging to virtual faults information is sent to multiple domain service interworking device MDSC.
Example one, referring to Fig. 2, it is assumed that from the node event about node A1/A4/A5/B1/B2/B5/B6/C1/C2/C4
Hinder information, then the corresponding virtual faults information of PNC matching virtual network topology generation (as shown in Figure 4) (including virtual faults section
Point A1 '/A4 '/A5 '/B1 '/B2 '/B5 '/B6 '/C1 '/C2 '/C4 '), belonging to A1/A4/A5/B1/B2/B5/B6/C1/C2/C4
Virtual link and A1/A4/A5/B1/B2/B5/B6/C1/C2/C4 belonging to virtual network, and be sent to MDSC.Assuming that coming
From the node failure information of node A2/A3/B3/B4/C3, then PNC matching virtual network topology determines node A2/A3/B3/B4/
C3 has been abstracted, then node A2/A3/B3/B4/C3 is the node in physical network topology, and PNC voluntarily handles node A2/A3/
The fault message of B3/B4/C3.It should be noted that node A1/A4/A5/B1/B2/B5/B6/C1/C2/C4 and dummy node

Two types, the first is the boundary node for abstracting single domain；Second is abstract single domain boundary node and some internal void
Quasi- node.The abstract mode of grey also there are two types of, the first is that abstract topology is automatically generated by configuration information, and second is root
According to path computing demand, supplement topology is generated on demand.
Illustratively, as shown in Fig. 2, if abstract strategy is abstract for white, whole nodes of PNC1 only abstract network A,
Such as node A1, A2, A3, A4, A5.If abstract strategy is abstract for grey, the boundary node of PNC1 only abstract network A, such as
Node A1 ', A4 ' and A5 '.If the abstract strategy that MDSC is sent to PNC1 is abstract for black, network A is abstracted as one by PNC1
Point.Similarly, whole nodes of PNC2 only abstract network B, whole nodes of PNC3 only abstract network C, abstract ways are the same as above-mentioned
PNC1 abstract network A, which is not described herein again.
Refering to what is shown in Fig. 2, assuming that network A is packet network, network B is OTN network, network C is packet network.If
PNC1, PNC2 and PNC3 progress grey are abstract and PNC1, PNC2 and PNC3 are OCH layers and LSP layers abstract, then MDSC is according to pumping
As the abstract view that topology information is got can be as shown in Figure 4.For Fig. 2, it is abstract after node include A1 '/A4 '/A5 '/
B1'/B2'/B5'/B6'/C1'/C2'.Wherein, there are LSP layers for network A and network C, but are not present OCH layers, and there are OCH for network B
Layer, but it is not present LSP layers.
