Should be clear and definite, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Embodiment one, and the embodiment of the invention provides a kind of method that limits the territory scale of ASON.In the ASON topology sketch map as shown in Figure 2, comprise territory X and the territory Y of ASON.Node A, B, C, D, E, F, G are the ASON node among the X of territory, and each node is added up according to self and known among the X of territory: the node of territory X adds up to 7, and (Traffic Engineering, TE) link adds up to 10 to traffic engineering.Node I, J, K, L, M, N, O, P are the ASON node among the Y of territory, and each node is added up according to self and known among the Y of territory: the node of territory Y adds up to 8, and TE Link adds up to 15.Node C among the X of territory links to each other through link with node J among the Y of territory, and territory Y is added territory X.This method specifically comprises the steps:
Step S201, node J sends message to node C, this message carry territory Y the node sum, TE Link is total and flag bit.
In the present embodiment, node J sends OSPF (Open Shortest Path First, ospf) hello packet of agreement or the DD of ospf protocol (Database Description, database description) message to node C.Carry node sum 8, TE Link sum 15 and the flag bit of node J place territory Y in this Hello or the Data Description (DD) packet.Wherein, flag bit is used for identifying Hello or Data Description (DD) packet to carry the node sum total with TE Link.
Step S202, node C confirms that according to flag bit message carries node sum and the TE Link sum of territory Y, extracts node sum and the TE Link sum of territory Y.
In the present embodiment; Node C receives Hello or the Data Description (DD) packet that node J sends; Confirm to carry in Hello or the Data Description (DD) packet node sum and TE Link sum, the node of the territory Y that carries in extraction Hello or the Data Description (DD) packet total 8 and the TE Link sum 15 of territory Y according to flag bit.
Step 203, node C judges that the single domain scale is out-of-limit.
In the present embodiment, the node threshold value of node C place territory X is 12, and the TE Link threshold value is 40.The node threshold value in ASON territory and TE Link threshold value can obtain through configuration.
Node C judges according to the out-of-limit strategy of ASON single domain scale whether the single domain scale is out-of-limit.
The out-of-limit strategy of ASON single domain scale comprises three kinds of modes, can selected to set by the user:
1) node confirm two territories node sum sum greater than node threshold value, judge that then the single domain scale is out-of-limit;
2) node confirm two territories TE Link sum sum greater than the TE Link threshold value, judge that then the single domain scale is out-of-limit;
3) node is confirmed node sum sum, the TE Link sum sum in two territories, as long as one of them greater than threshold value, judges that then the single domain scale is out-of-limit.That is:
Node is confirmed the node sum sum in two territories greater than node threshold value, and the TE Link sum sum of further confirming two territories judges then that also greater than the TE Link threshold value single domain scale is out-of-limit;
Node is confirmed the node sum sum in two territories less than node threshold value, and the TE Link sum sum of further confirming two territories judges then that greater than the TE Link threshold value single domain scale is out-of-limit;
Node is confirmed the TE Link sum sum in two territories less than the TE Link threshold value, and the node sum sum of further confirming two territories judges then that greater than node threshold value the single domain scale is out-of-limit.
The size of the size of node sum sum and node threshold value, TE Link sum sum and TE Link threshold value; Judgement order to the two in the present embodiment does not limit; Promptly can be first the size of decision node sum sum and node threshold value, also can judge the size of total sum of TE Link and TE Link threshold value earlier.
In the present embodiment, the out-of-limit strategy of ASON single domain scale that the user sets is: 3) node is confirmed node sum sum, TE Link sum sum, as long as one of them greater than threshold value, judges that then the single domain scale is out-of-limit.
Node C is with node sum 8 additions of node sum 7 with the territory Y of territory X, and obtaining node sum sum is 15, greater than the node threshold value 12 of territory X; With the TE Link sum 10 and total 15 additions of the TE Link of territory Y of territory X, obtaining TE Link sum sum is 25, less than the TE Link threshold value 40 of territory X.
The node sum sum of territory X and territory Y is greater than the node threshold value of territory X, and node C judges that the single domain scale is out-of-limit.
Step S204, node C abandons this message.
In the present embodiment, node C judges that the single domain scale is out-of-limit, abandons Hello or Data Description (DD) packet that node J sends.
If among the step S201 hello packet of node J through ospf protocol carry territory Y the node sum, TE Link is total and flag; Correspondingly; Node C abandons the hello packet that node J sends among the step S204, and then node C and node J can not form neighborhood, information that can't inundation adding territory; Territory Y can not add territory X, the scale of the territory X of restriction ASON;
If among the step S201 Data Description (DD) packet of node J through ospf protocol carry territory Y the node sum, TE Link is total and flag; Correspondingly; Node C abandons the Data Description (DD) packet that node J sends among the step S204, then can not form syntople between node C and the node J, information that can't inundation adding territory; Territory Y can not add territory X, the scale of the territory X of restriction ASON.
Embodiment one has described the situation that territory Y adds territory X, wherein, and the situation that territory X and territory Y only have a pair of node to link to each other through link.Territory X has n (n＞=1) with territory Y node is linked to each other through link; For many situation that node is linked to each other through link are arranged; Node C that describes among the processing of every pair of node and the embodiment one and the processing of node J are similar; The node in the territory of every pair of node comparison is total, TE Link is total and the respective doors limit value all is identical, and therefore whether out-of-limit deterministic process and judged result is similar to every pair of node to the single domain scale.If every pair through in the continuous node of link; The node that receives Hello or Data Description (DD) packet confirms that the single domain scale is out-of-limit; Abandon Hello or Data Description (DD) packet, then can not form syntople between node, can't inundation add the information in territory; Then territory Y can not add territory X, reaches the purpose according to threshold value restriction ASON single domain scale.
Add another ASON territory for an ASON territory, a kind of special circumstances are arranged: the territory that request adds only comprises a node, and promptly individual node adds the ASON territory.In such cases; Can regard individual node as a minimum territory; The node that carries its territory, place in Hello that individual node sends or the Data Description (DD) packet adds up to 1, TE Link adds up to 1; Receive message with individual node through the node that is added in the territory that link links to each other, carry out the whether out-of-limit judgement of single domain scale, reach purpose thus according to threshold value restriction ASON single domain scale.Through embodiment two this situation is described in detail below.
Embodiment two, and the embodiment of the invention provides a kind of method that limits the territory scale of ASON.In the ASON topology sketch map as shown in Figure 3, comprise territory X and the node H of ASON.Node A, B, C, D, E, F, G are the ASON node among the X of territory, and each node is added up according to self and obtained among the X of territory: the node of territory X adds up to 7, and TE Link adds up to 10.Node B among the X of territory links to each other through link with node H, and node H is added territory X.This method specifically comprises the steps:
Step S301, node H sends message to Node B, and this message carries node sum, TE Link sum and flag bit.
In the present embodiment, node H sends the hello packet of ospf protocol or the Data Description (DD) packet of ospf protocol to Node B.Carry node sum 1, TE Link sum 1 and flag in this Hello or the Data Description (DD) packet.Wherein, flag bit is used for identifying Hello or Data Description (DD) packet to carry the node sum total with TE Link.
Step S302, Node B confirms that according to flag bit message carries node sum and TE Link sum, extracts node sum and TE Link sum.
In the present embodiment, Node B receives Hello or the Data Description (DD) packet that node H sends, and confirms to carry in Hello or the Data Description (DD) packet node sum and TE Link sum according to flag bit, extracts the node sum 1 and TE Link sum 1 that carry in Hello or the Data Description (DD) packet.
Step S303, Node B judges that the single domain scale is out-of-limit.
In the present embodiment, the node sum threshold value of Node B place territory X is 7, and the TE Link threshold value is 20.The node threshold value in ASON territory and TE Link threshold value can obtain through configuration.
Node B judges according to the out-of-limit strategy of ASON single domain scale whether the single domain scale is out-of-limit.The out-of-limit strategy of ASON single domain scale comprises three kinds of modes, with consistent among the embodiment one step S203.
In the present embodiment, the out-of-limit strategy of ASON single domain scale that the user sets is: 1) node confirm two territories node sum sum greater than node threshold value, judge that then the single domain scale is out-of-limit.
Node B is with node sum 1 addition of carrying in the node of territory X sum 7 and Hello or the Data Description (DD) packet, and obtaining node sum sum is 8, greater than the node threshold value 7 of territory X.
Node sum sum is greater than the node threshold value of territory X, and Node B judges that the single domain scale is out-of-limit.
Step S304, Node B abandons this message.
In the present embodiment, Node B judges that the single domain scale is out-of-limit, abandons Hello or Data Description (DD) packet that node H sends.
If node H carries node sum, TE Link sum and flag through the hello packet of ospf protocol among the step S301; Correspondingly; Node B abandons the hello packet that node H sends among the step S304, and then Node B and node H can not form neighborhood, information that can't inundation adding territory; Node H can not add territory X, the scale of the territory X of restriction ASON;
If node H carries node sum, TE Link sum and flag through the Data Description (DD) packet of ospf protocol among the step S301; Correspondingly; Node B abandons the Data Description (DD) packet that node H sends among the step S304, then can not form syntople between Node B and the node H, information that can't inundation adding territory; Node H can not add territory X, the scale of the territory X of restriction ASON.
In the foregoing description, judge according to different strategies whether the single domain scale is out-of-limit, node can 1) size of decision node sum sum and node threshold value only; 2) only judge the size of TE Link sum sum and TE Link threshold value; 3) size of the size of node sum sum and node threshold value, TE Link sum sum and TE Link threshold value, the two all will be judged.Correspondingly, in the message (like the Hello or the Data Description (DD) packet of ospf protocol) can: 1) only carry the node sum; 2) only carry the TE Link sum; 3) carry node sum and TE Link sum.For the situation of the sum of decision node only sum with the size of node threshold value, message also can carry the node sum and TE Link total, like embodiment two; Equally, for the situation of the size of only judging TE Link sum sum and TE Link threshold value, message also can carry node sum and TE Link sum.
