In embodiments of the present invention, access network element and non-access network element generate NE management IP address according to preset management address create-rule respectively, by described NE management IP address configuration on management loopback interface, and create the OSPF routing instances of DCN; When determining that Ethernet interface state meets pre-conditioned, create ethernet sub-interface, generate the IP address routing table of DCN, and by net element information configuration to OSPF Routing Protocol; EMS resolves each net element information that access network element sends, and creates the logical ne corresponding with non-access network element, and sets up the connection between non-access network element;
Wherein, described net element information comprises the net element information of access network element and non-access network element.
Fig. 1 is the embodiment of the present invention one DCN activating method schematic flow sheet, and as shown in Figure 1, the present embodiment DCN activating method comprises:
Step 101: access network element and non-access network element generate NE management IP address according to preset management address create-rule respectively, by described NE management IP address configuration on management loopback interface, and creates the OSPF routing instances of DCN;
Before this step, described method also comprises: access network element and non-access network element create DCN webmaster example and management loopback interface respectively;
Here, described DCN webmaster example refers to for the special DCN virtual flow-line of DCN network creation forwards (VRF, VirtualRouteForwarding) example, by the management route of PTN network and the isolation of business route, can avoid mutual interference.
Further, described management address create-rule comprises: judge whether network element supports network element identify label (NEID, NetElemetIdentification) be mapped to NE management IP address, if supported, NEID be mapped to NE management IP address; If do not supported, network element medium access control (MAC, MediaAccessControl) address maps is become NE management IP address;
Accordingly, access network element and non-access network element generate NE management IP address according to preset management address create-rule respectively and comprise: access network element and non-access network element judge self whether to support that NEID generates NE management IP address respectively, if supported, directly the NEID of self is mapped to NE management IP address; If do not supported, the MAC Address of self is mapped to NE management IP address;
Wherein, described NEID is the unique numberization mark of network element, and length is 4 bytes, and by the write when equipment generates delivery of each manufacturer, in the embodiment of the present invention, NEID definition rule is as follows:
Equipment NEID is defined as 4 bytes, 32bit sequence number, and NEID defines at present and uses 24bit, and wherein BIT [20 ~ 27] retains, and the 1st front 4 bit of byte are used for marking equipment type, and 20 bit of remaining byte are used for marking equipment hardware sequence number.NEID supports non-volatile memory, backboard is existed to the equipment of memory space, and NEID requires to be kept in backboard nonvolatile storage; Backboard be there is no to the equipment of memory space, be then kept in the non-volatile storage space of equipment master control borad;
Described NE management IP address is formulated for three sections by byte from a high position to low level:
First section: instrument factory trading company, takies the first byte of IPv4 address, is that different telecom equipment vendors specifies fixing number by operator according to network requirement;
Second section: unit type, takies the high 4bit of IPv4 address second byte, and the PTN device being respective different model by equipment vendors is distributed;
3rd section: IP address sequence number, takies low four bit of IPv4 address second byte, the 3rd byte and nybble.In theory, for same manufacturer with a PTN device, network is maximum can support 0xfffff, namely 1048575, can meet the network demand of telecom operators completely.
Further, when network element supports that NEID generates NE management IP address, when NEID being mapped to NE management IP address, described NE management IP address according to the create-rule of NEID is:
